Corticosteroid injections may worsen knee OA progression
Injecting hyaluronic acid (HA) instead, or managing the condition without injections, may better preserve knee structure and cartilage, according to results of two related studies presented at the annual meeting of the Radiological Society of North America.
The findings come nonrandomized, observational cohort studies, leading knee OA experts to call for further study in randomized trial settings. In the meantime, shared decision-making between patients and clinicians is advised on the use of these injections.
For knee OA, most patients seek a noninvasive treatment for symptomatic relief. “At least 10% of these patients undergo local treatment with injectable corticosteroids or hyaluronic acid,” the lead author of one of the studies, Upasana Upadhyay Bharadwaj, MD, research fellow in musculoskeletal radiology at the University of California, San Francisco, said in a video press release.
Researchers in both studies used data and images from the Osteoarthritis Initiative (OAI), a multicenter, longitudinal, observational study of 4,796 U.S. patients aged 45-79 years with knee OA. Participants were enrolled from February 2004 to May 2006.
The OAI maintains a natural history database of information regarding participants’ clinical evaluation data, x-rays, MRI scans, and a biospecimen repository. Data are available to researchers worldwide.
Two studies draw similar conclusions
In one study, Dr. Bharadwaj and colleagues found that HA injections appeared to show decreased knee OA progression in bone marrow lesions.
They investigated 8 patients who received one CS injection, 12 who received one HA injection, and 40 control persons who received neither treatment. Participants were propensity-score matched by age, sex, body mass index (BMI), Kellgren-Lawrence (KL) grade, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and Physical Activity Scale for the Elderly (PASE).
The researchers semiquantitatively graded three Tesla MRI scans that had been obtained at baseline, 2 years before the injection, and 2 years after the injection, using whole-organ MRI score (WORMS) for the meniscus, bone marrow lesions, cartilage, joint effusion, and ligaments.
They quantified OA progression using the difference in WORMS between baseline and 2-year follow-up, and they used linear regression models, adjusted for age, sex, BMI, KL grade, WOMAC, and PASE, to identify the link between type of injection and progression of WORMS.
At 2 years, the authors found a significant association between CS injection and postinjection progression of WORMS over 2 years for the knee overall, the lateral meniscus, lateral cartilage, and medial cartilage. There was no significant link between HA injection and postinjection progression of WORMS or between either injection type and progression of pain, as quantified by WOMAC. There was also no significant difference in progression of WORMS over the 2 years prior to injection for CS and HA injections.
“Corticosteroid injections must be administered with caution with respect to long-term effects on osteoarthritis,” Dr. Bharadwaj advised. “Hyaluronic acid injections, on the other hand, may slow down progression of knee osteoarthritis and alleviate long-term effects while offering similar symptomatic relief to corticosteroid injections. Overall, they are perhaps a safer alternative when looking at medium- and long-term disease course of knee osteoarthritis.”
In the second study, lead author Azad Darbandi, MS, a fourth-year medical student at Chicago Medical School, North Chicago, and colleagues found that patients who received CS injections experienced significantly more medial joint space narrowing.
They identified 210 knees with imaging at baseline and at 48 months that received CS injections, and 59 that received HA injections; 6,827 knees served as controls. The investigators matched 50 patients per group on the basis of confounding factors, which included age, sex, BMI, comorbidities, surgery, and semiquantitative imaging outcomes at baseline. They performed ANCOVA testing using 48-month semiquantitative imaging outcomes as dependent variables and confounding variables as covariates.
The researchers analyzed joint space narrowing, KL grade, and tibia/femur medial/lateral compartment osteophyte formation and sclerosis.
At 4 years, the average KL grade in the CS group was 2.79, it was 2.11 in the HA group,;and it was 2.37 in the control group. Intergroup comparisons showed significant differences in KL grade between CS and HA groups and between CS and control groups. Medial compartment joint space narrowing was 1.56 in the CS group, 1.11 in the HA group, and 1.18 in controls. There was a significant difference between the CS and control groups. Other dependent variables were not significant.
“These preliminary results suggest that corticosteroid injections accelerated the radiographic progression of osteoarthritis, specifically medial joint space narrowing and Kellgren-Lawrence grading, whereas hyaluronic acid injections did not,” Mr. Darbandi said in an interview.
“OA radiographic progression does not always correlate with clinical progression, and further research is needed,” he added.
Proper matching of patients at baseline for confounding factors is a strength of the study, Mr. Darbandi said, while the retrospective study design is a weakness.
Experts share their perspectives on the preliminary results
Michael M. Kheir, MD, assistant professor of orthopedic surgery at the University of Michigan Health System, who was not involved in the studies, said he would like to see further related research.
“Perhaps steroid injections are not as benign as they once seemed,” he added. “They should be reserved for patients who already have significant arthritis and are seeking temporary relief prior to surgical reconstruction with a joint replacement, or for patients with recalcitrant pain after having already tried HA injections.”
William A. Jiranek, MD, professor and orthopedic surgeon at Duke Health in Morrisville, N.C., who also was not involved in the studies, was not surprised by the findings.
“It is important to do these studies to learn that steroid injections do not come with zero cost,” he said.
“I am pretty sure that a percentage of these patients had no cartilage loss at all,” he added. “We need to understand which OA phenotypes are not at risk of progressive cartilage loss from steroid injections.”
Annunziato (Ned) Amendola, MD, professor and sports medicine orthopedic surgeon at Duke Health in Durham, N.C., who was also not involved in the studies, said he would like to know how injection effectiveness and activity level are related.
“If the injections were effective at relieving pain, and the patients were more active, that may have predisposed to more joint wear,” he said. “It’s like tires that last longer if you don’t abuse them.”
Shared decision-making and further research recommended
Amanda E. Nelson, MD, associate professor of medicine in the division of rheumatology, allergy, and immunology at the University of North Carolina at Chapel Hill, said: “The lack of randomization introduces potential biases around why certain therapies (CS injection, HA injection, or neither) were selected over others (such as disease severity, preference, comorbid conditions, other contraindications, etc), thus making interpretation of the findings challenging.
“The causal relationship remains in question, and questions around the efficacy of intra-articular HA in particular, and the ideal settings for intra-articular therapy in general, persist,” noted Dr. Nelson, who was also not involved in the studies. “Thus, shared decision-making between patients and their providers is essential when considering these options.”
C. Kent Kwoh, MD, professor of medicine and medical imaging at the University of Arizona and director of the University of Arizona Arthritis Center, both in Tucson, said in an interview that these types of studies are important because CS injections are common treatments for knee OA, they are recommended in treatment guidelines, and other good options are lacking.
But he pointed out that the results of these two studies need to be interpreted with caution and should not be used to decide the course of treatment.
“These data are hypothesis generating. They suggest association, but they do not show causation,” said Dr. Kwoh, who was also not involved in the studies. “Both studies are secondary analyses of data collected from the OAI, which was not specifically designed to answer the questions these studies are posing.
“The OAI was not a treatment study, and participants were seen only once a year or so. They may have had joint injections anytime from only days to around 1 year before their visit, and their levels of activity or pain just prior to or just after their joint injections were not reported,” Dr. Kwoh explained.
The reasons why patients did or did not receive a specific joint injection – including their socioeconomic status, race, access to insurance, and other confounding factors – were not assessed and may have affected the results, he added.
The fact that both studies used the same data and came to the same conclusions gives the conclusions some strength, he said, but “the gold standard to understanding causation would be a randomized, controlled trial.”
Mr. Darbandi’s research received grant support from Boeing, His c-authors, as well as all experts not involved in the studies, reported no relevant financial relationshiips. Dr. Bharadwaj did not provide conflict-of-interest and funding details. Dr. Kwoh reported membership on panels that have developed guidelines for the management of knee OA.

FROM RSNA 2022
Is there hope in the fight against aging?
For many years, it has been believed that the aging process is inevitable and that age-related diseases cannot be prevented or reversed. For example, the U.S. Food and Drug Administration does not recognize aging as an indication for drug approval because there are no markers to determine whether possible treatments have a significant impact on the hallmarks of aging.
The field of geroscience aims to find ways to change this by delaying the onset of age-related diseases or by extending the life span.
Perspectives from this meeting were published in a report.
An abridged glossary
- Senescent cells: These are old cells with irreversibly damaged DNA; they strongly resist apoptosis. Thus, they are not eliminated and continue to secrete pathogenic proinflammatory molecules.
- Senolytics: This is a class of compounds that promote the removal of senescent cells from the body.
- Autophagy: This is a process that promotes protein degradation, which is attenuated with aging and that impedes the aggregation of proteins harmful to cell function, particularly those of the central nervous system.
- Proteostasis: This is the dynamic regulation of protein homeostasis.
- Epigenetics: This is the field of biology that studies phenotype changes that are not caused by changes in DNA sequencing and that continue to affect cellular division.
- Metabolome: This refers to small molecules that make up the building blocks of all organismal features, from cell membranes to metabolic cycles to genes and proteins.
- Translational research: This involves applying primary research results to clinical research and vice versa.
Possible research topics
Senescence not only occurs with age but also drives aging. At the meeting, evidence was provided that senescent cells may exacerbate the clinical course of older adults in cases of infections (for example, COVID-19) as they lead to cytokine storms.
Experiments on old mice that have undergone genetic modification of senescent cells or the administration of “senolytic cocktails” composed of dasatinib plus quercetin protected the animals from the effects of viral infections. This finding corroborates the idea that factors involved in biological aging increase vulnerability and could be modified through treatment.
Alzheimer’s disease is an example of the effects of cellular senescence. Senescent cells develop a senescence-associated secretory phenotype that can be toxic to neighboring healthy cells and can allow senescence to propagate within tissues. This effect makes Alzheimer’s disease an essential focal point when studying the use of senolytics. In addition, agents that stimulate autophagy may be of interest for treating degenerative diseases.
Assessing therapeutic effects
It may be possible to assess the therapeutic effects of drug candidates using the following biomarkers.
- Growth hormone and type 1 insulin-like growth factor (IGF-1): Older adults are often prescribed growth hormone. However, recent data suggest that doing so is not advantageous to this patient population, because it antagonizes proteostasis and other cell maintenance mechanisms in older age. Experimental studies and studies conducted on centenarians suggest that low growth hormone and IGF-1 levels contribute to longevity and may be therapeutic biomarkers.
- Epigenetics: DNA methylation is a method that offers an “epigenetic clock” to compare biological age with chronologic age. Higher epigenetic age was associated with increased mortality risk, breast cancer, and nonalcoholic fatty liver disease. Therefore, it could also be a therapeutic biomarker.
- Metabolomics: Studying metabolomes facilitates the identification of the link between genetic polymorphisms and longevity, as most polymorphisms explain less than 0.5% of longevity variations.
- New translational strategy: It is common practice to treat each age-related disease individually. An alternative strategy would be to target the hallmarks of biological aging to prevent these diseases from developing. The rate of biological aging correlates with the speed of damage accumulation at the macromolecular, organelle, and cellular levels. It also affects the capacity of the body to repair this damage. The assessment of biomarkers would make possibile research into the effects of short- and long-term treatments that minimize damage and enhance resilience related to diseases common with aging.
New translational research
The report highlights two translational research models: the in-depth study of centenarians and the analysis of how immune aging makes older adults vulnerable to COVID-19. The impact of impaired immunity on aging became particularly evident during the pandemic. However, to home in on immunity as a therapeutic target and to better understand immune resilience, the specific nature of immune and biological deficits still need to be defined.
Metformin is among the therapeutic agents under investigation in cutting-edge clinical research. Its effect on aging will be studied in the Targeting Aging with Metformin (TAME) clinical trial. This trial is the first to study aging outcomes. The goal is to create a regulatory framework that future therapies can follow to achieve FDA approval.
There are three promising therapeutic platforms among the cutting-edge research studies. The first aims to produce adenosine triphosphate, levels of which decline dramatically with aging. The second aims to promote autophagy to remove cellular waste to treat neurodegenerative diseases. The third reprograms the epigenome to a younger state.
Research on mitochondrial dysfunction is relevant because it is highly involved in age-related diseases. Mitochondrial-derived peptides could potentially serve as biomarkers of mitochondrial function in aging studies and become promising therapeutic targets in age-related diseases. One of these peptides, humanin, has been demonstrated to exert protective effects on the heart, brain, and liver. Researchers observed that mitochondrial proteins are age-dependent and are suppressed by growth hormone and IGF-1. They also found that humanin levels are correlated with endothelial function. Data from animal studies have shown that sustained humanin levels are positively linked to longevity; these findings are mirrored in data from centenarians and their offspring, who have higher levels of humanin.
The formation of a Translational Geroscience Network composed of several scientists from various institutions should accelerate the application of this understanding. Despite the ongoing investigational and clinical studies, senolytics should not be regarded as extending life span or treating certain conditions, because their full safety profiles have not yet been elucidated.
Conclusion
Geroscience faces challenges in dealing with age-related problems. It is hoped that these challenges will be overcome through investigational and clinical studies on the mechanisms involved in aging. In-depth study of the interactions of underlying mechanisms of aging are needed to answer the following questions:
- Is there a hierarchical relationship among these mechanisms?
- Are there organ or cell-type differences in the interactions among these mechanisms?
- Is it possible to achieve a synergistic effect through combined interventions targeting several of the processes that drive aging?
It is complicated, but researchers are starting to see the light at the end of the tunnel.

Assessing therapeutic effects
It may be possible to assess the therapeutic effects of drug candidates using the following biomarkers.
- Growth hormone and type 1 insulin-like growth factor (IGF-1): Older adults are often prescribed growth hormone. However, recent data suggest that doing so is not advantageous to this patient population, because it antagonizes proteostasis and other cell maintenance mechanisms in older age. Experimental studies and studies conducted on centenarians suggest that low growth hormone and IGF-1 levels contribute to longevity and may be therapeutic biomarkers.
- Epigenetics: DNA methylation is a method that offers an “epigenetic clock” to compare biological age with chronologic age. Higher epigenetic age was associated with increased mortality risk, breast cancer, and nonalcoholic fatty liver disease. Therefore, it could also be a therapeutic biomarker.
- Metabolomics: Studying metabolomes facilitates the identification of the link between genetic polymorphisms and longevity, as most polymorphisms explain less than 0.5% of longevity variations.
- New translational strategy: It is common practice to treat each age-related disease individually. An alternative strategy would be to target the hallmarks of biological aging to prevent these diseases from developing. The rate of biological aging correlates with the speed of damage accumulation at the macromolecular, organelle, and cellular levels. It also affects the capacity of the body to repair this damage. The assessment of biomarkers would make possibile research into the effects of short- and long-term treatments that minimize damage and enhance resilience related to diseases common with aging.
New translational research
The report highlights two translational research models: the in-depth study of centenarians and the analysis of how immune aging makes older adults vulnerable to COVID-19. The impact of impaired immunity on aging became particularly evident during the pandemic. However, to home in on immunity as a therapeutic target and to better understand immune resilience, the specific nature of immune and biological deficits still need to be defined.
Metformin is among the therapeutic agents under investigation in cutting-edge clinical research. Its effect on aging will be studied in the Targeting Aging with Metformin (TAME) clinical trial. This trial is the first to study aging outcomes. The goal is to create a regulatory framework that future therapies can follow to achieve FDA approval.
There are three promising therapeutic platforms among the cutting-edge research studies. The first aims to produce adenosine triphosphate, levels of which decline dramatically with aging. The second aims to promote autophagy to remove cellular waste to treat neurodegenerative diseases. The third reprograms the epigenome to a younger state.
Research on mitochondrial dysfunction is relevant because it is highly involved in age-related diseases. Mitochondrial-derived peptides could potentially serve as biomarkers of mitochondrial function in aging studies and become promising therapeutic targets in age-related diseases. One of these peptides, humanin, has been demonstrated to exert protective effects on the heart, brain, and liver. Researchers observed that mitochondrial proteins are age-dependent and are suppressed by growth hormone and IGF-1. They also found that humanin levels are correlated with endothelial function. Data from animal studies have shown that sustained humanin levels are positively linked to longevity; these findings are mirrored in data from centenarians and their offspring, who have higher levels of humanin.
The formation of a Translational Geroscience Network composed of several scientists from various institutions should accelerate the application of this understanding. Despite the ongoing investigational and clinical studies, senolytics should not be regarded as extending life span or treating certain conditions, because their full safety profiles have not yet been elucidated.
Conclusion
Geroscience faces challenges in dealing with age-related problems. It is hoped that these challenges will be overcome through investigational and clinical studies on the mechanisms involved in aging. In-depth study of the interactions of underlying mechanisms of aging are needed to answer the following questions:
- Is there a hierarchical relationship among these mechanisms?
- Are there organ or cell-type differences in the interactions among these mechanisms?
- Is it possible to achieve a synergistic effect through combined interventions targeting several of the processes that drive aging?
It is complicated, but researchers are starting to see the light at the end of the tunnel.

For many years, it has been believed that the aging process is inevitable and that age-related diseases cannot be prevented or reversed. For example, the U.S. Food and Drug Administration does not recognize aging as an indication for drug approval because there are no markers to determine whether possible treatments have a significant impact on the hallmarks of aging.
The field of geroscience aims to find ways to change this by delaying the onset of age-related diseases or by extending the life span.
Perspectives from this meeting were published in a report.
An abridged glossary
- Senescent cells: These are old cells with irreversibly damaged DNA; they strongly resist apoptosis. Thus, they are not eliminated and continue to secrete pathogenic proinflammatory molecules.
- Senolytics: This is a class of compounds that promote the removal of senescent cells from the body.
- Autophagy: This is a process that promotes protein degradation, which is attenuated with aging and that impedes the aggregation of proteins harmful to cell function, particularly those of the central nervous system.
- Proteostasis: This is the dynamic regulation of protein homeostasis.
- Epigenetics: This is the field of biology that studies phenotype changes that are not caused by changes in DNA sequencing and that continue to affect cellular division.
- Metabolome: This refers to small molecules that make up the building blocks of all organismal features, from cell membranes to metabolic cycles to genes and proteins.
- Translational research: This involves applying primary research results to clinical research and vice versa.
Possible research topics
Senescence not only occurs with age but also drives aging. At the meeting, evidence was provided that senescent cells may exacerbate the clinical course of older adults in cases of infections (for example, COVID-19) as they lead to cytokine storms.
Experiments on old mice that have undergone genetic modification of senescent cells or the administration of “senolytic cocktails” composed of dasatinib plus quercetin protected the animals from the effects of viral infections. This finding corroborates the idea that factors involved in biological aging increase vulnerability and could be modified through treatment.
Alzheimer’s disease is an example of the effects of cellular senescence. Senescent cells develop a senescence-associated secretory phenotype that can be toxic to neighboring healthy cells and can allow senescence to propagate within tissues. This effect makes Alzheimer’s disease an essential focal point when studying the use of senolytics. In addition, agents that stimulate autophagy may be of interest for treating degenerative diseases.

Antipsychotic shows benefit for Alzheimer’s agitation
SAN FRANCISCO – In a widely anticipated report,
Members of a panel of dementia specialists here at the 15th Clinical Trials on Alzheimer’s Disease (CTAD) conference said that the results were encouraging. But they also noted that the available data make it difficult to understand the impact of the drug on the day-to-day life on patients.
“I’d like to be able to translate that into something else to understand the risk benefit calculus,” said neurologist and neuroscientist Alireza Atri, MD, PhD, of Banner Sun Health Research Institute in Phoenix. “How does it affect the patients themselves, their quality of life, and the family members and their burden?”
Currently, there’s no Food and Drug Administration–approved treatment for agitation in AD.
In 2015, the FDA approved brexpiprazole, an oral medication, as a treatment for schizophrenia and an adjunctive treatment for major depressive disorder (MDD). It is an expensive drug with an average retail price per GoodRx of $1,582 per month, and no generic is available.
Researchers released the results of a trio of phase 3 clinical trials at CTAD that examined various doses of brexpiprazole. The results of the first two trials had been released earlier in 2018.
Three trials
All trials were multicenter, 12-week, randomized, double-blind and placebo-controlled.
Study participants were aged 55-90 years, had probable AD diagnoses, and had agitation per various scales. The average age in the groups was 74 years, 56.0%-61.7% were women, and 94.3%-98.1% were White.
The first trial examined two fixed doses (1 mg/d, n = 137; and 2 mg/d, n = 140) or placebo (n = 136). “The study initially included a 0.5 mg/day arm,” the researchers reported, “which was removed in a protocol amendment, and patients randomized to that arm were not included in efficacy analyses.”
The second trial looked at a flexible dose (0.5-2 mg/d, n = 133) or placebo (n = 137).
In a CTAD presentation, Nanco Hefting of Lundbeck, a codeveloper of the drug, said that the researchers learned from the first two trials that 2 mg/d might be an appropriate dose, and the FDA recommended they also examine 3 mg/day. As a result, the third trial examined two fixed doses (2 mg/d, n = 75; 3 mg/d, n = 153; or placebo, n = 117).
In the third trial, both the placebo and drug groups improved per a measurement of agitation; those in the drug group improved somewhat more.
The mean change in baseline on the Cohen-Mansfield Agitation Inventory scale – the primary endpoint – was –5.32 for the 2-mg/d and 3-mg/d groups vs. placebo (P = .0026); the score in the placebo group fell by about 18 and by about 22 in the drug group.
The key secondary endpoint was an improvement from baseline to week 12 in the Clinical Global Impression–Severity (CGI-S) score related to agitation. Compared with the placebo group, this score was –0.27 in the drug group (P = .0078). Both scores hovered around –1.0.
Safety data show the percentage of treatment-emergent events ranged from 45.9% in the placebo group to 49.0%-56.8% for brexpiprazole in the three trials. The percentage of these events leading to discontinuation was 6.3% among those receiving the drug and 3.4% in the placebo group.
University of Exeter dementia researcher Clive Ballard, MD, MB ChB, one of the panelists who discussed the research after the CTAD presentation, praised the trials as “well-conducted” and said that he was pleased that subjects in institutions were included. “It’s not an easy environment to do trials in. They should be really commended for doing for doing that.”
But he echoed fellow panelist Dr. Atri by noting that more data are needed to understand how well the drug works. “I would like to see the effect sizes and a little bit more detail to understand the clinical meaningfulness of that level of benefit.”
What’s next? A spokeswoman for Otsuka, a codeveloper of brexpiprazole, said that it hopes to hear in 2023 about a supplemental new drug application that was filed in November 2022.
Otsuka and Lundbeck funded the research. Mr. Hefting is an employee of Lundbeck, and several other authors work for Lundbeck or Otsuka. The single non-employee author reports various disclosures. Disclosures for Dr. Atri and Dr. Ballard were not provided.

AT CTAD 2022
SSRI tied to improved cognition in comorbid depression, dementia
The results of the 12-week open-label, single-group study are positive, study investigator Michael Cronquist Christensen, MPA, DrPH, a director with the Lundbeck pharmaceutical company, told this news organization before presenting the results in a poster at the 15th Clinical Trials on Alzheimer’s Disease conference.
“The study confirms earlier findings of improvement in both depressive symptoms and cognitive performance with vortioxetine in patients with depression and dementia and adds to this research that these clinical effects also extend to improvement in health-related quality of life and patients’ daily functioning,” Dr. Christensen said.
“It also demonstrates that patients with depression and comorbid dementia can be safely treated with 20 mg vortioxetine – starting dose of 5 mg for the first week and up-titration to 10 mg at day 8,” he added.
However, he reported that Lundbeck doesn’t plan to seek approval from the U.S. Food and Drug Administration for a new indication. Vortioxetine received FDA approval in 2013 to treat MDD, but 3 years later the agency rejected an expansion of its indication to include cognitive dysfunction.
“Vortioxetine is approved for MDD, but the product can be used in patients with MDD who have other diseases, including other mental illnesses,” Dr. Christensen said.
Potential neurotransmission modulator
Vortioxetine is a selective serotonin reuptake inhibitor and serotonin receptor modulator. According to Dr. Christensen, evidence suggests the drug’s receptor targets “have the potential to modulate neurotransmitter systems that are essential for regulation of cognitive function.”
The researchers recruited 83 individuals aged 55-85 with recurrent MDD that had started before the age of 55. All had MDD episodes within the previous 6 months and comorbid dementia for at least 6 months.
Of the participants, 65.9% were female. In addition, 42.7% had Alzheimer’s disease, 26.8% had mixed-type dementia, and the rest had other types of dementia.
The daily oral dose of vortioxetine started at 5 mg for up to week 1 and then was increased to 10 mg. It was then increased to 20 mg or decreased to 5 mg “based on investigator judgment and patient response.” The average daily dose was 12.3 mg.
In regard to the primary outcome, at week 12 (n = 70), scores on the Montgomery-Åsberg Depression Rating Scale (MADRS) fell by a mean of –12.4 (.78, P < .0001), which researchers deemed to be a significant reduction in severe symptoms.
“A significant and clinically meaningful effect was observed from week 1,” the researchers reported.
“As a basis for comparison, we typically see an improvement around 13-14 points during 8 weeks of antidepressant treatment in adults with MDD who do not have dementia,” Dr. Christensen added.
More than a third of patients (35.7%) saw a reduction in MADRS score by more than 50% at week 12, and 17.2% were considered to have reached MDD depression remission, defined as a MADRS score at or under 10.
For secondary outcomes, the total Digit Symbol Substitution test score grew by 0.65 (standardized effect size) by week 12, showing significant improvement (P < .0001). In addition, participants improved on some other cognitive measures, and Dr. Christensen noted that “significant improvement was also observed in the patients’ health-related quality of life and daily functioning.”
A third of patients had drug-related treatment-emergent adverse events.
Vortioxetine is one of the most expensive antidepressants: It has a list price of $444 a month, and no generic version is currently available.
Small trial, open-label design
In a comment, Claire Sexton, DPhil, senior director of scientific programs and outreach at the Alzheimer’s Association, said the study “reflects a valuable aspect of treatment research because of the close connection between depression and dementia. Depression is a known risk factor for dementia, including Alzheimer’s disease, and those who have dementia may experience depression.”
She cautioned, however, that the trial was small and had an open-label design instead of the “gold standard” of a double-blinded trial with a control group.
The study was funded by Lundbeck, where Dr. Christensen is an employee. Another author is a Lundbeck employee, and a third author reported various disclosures. Dr. Sexton reported no disclosures.

“Vortioxetine is approved for MDD, but the product can be used in patients with MDD who have other diseases, including other mental illnesses,” Dr. Christensen said.
Potential neurotransmission modulator
Vortioxetine is a selective serotonin reuptake inhibitor and serotonin receptor modulator. According to Dr. Christensen, evidence suggests the drug’s receptor targets “have the potential to modulate neurotransmitter systems that are essential for regulation of cognitive function.”
The researchers recruited 83 individuals aged 55-85 with recurrent MDD that had started before the age of 55. All had MDD episodes within the previous 6 months and comorbid dementia for at least 6 months.
Of the participants, 65.9% were female. In addition, 42.7% had Alzheimer’s disease, 26.8% had mixed-type dementia, and the rest had other types of dementia.
The daily oral dose of vortioxetine started at 5 mg for up to week 1 and then was increased to 10 mg. It was then increased to 20 mg or decreased to 5 mg “based on investigator judgment and patient response.” The average daily dose was 12.3 mg.
In regard to the primary outcome, at week 12 (n = 70), scores on the Montgomery-Åsberg Depression Rating Scale (MADRS) fell by a mean of –12.4 (.78, P < .0001), which researchers deemed to be a significant reduction in severe symptoms.
“A significant and clinically meaningful effect was observed from week 1,” the researchers reported.
“As a basis for comparison, we typically see an improvement around 13-14 points during 8 weeks of antidepressant treatment in adults with MDD who do not have dementia,” Dr. Christensen added.
More than a third of patients (35.7%) saw a reduction in MADRS score by more than 50% at week 12, and 17.2% were considered to have reached MDD depression remission, defined as a MADRS score at or under 10.
For secondary outcomes, the total Digit Symbol Substitution test score grew by 0.65 (standardized effect size) by week 12, showing significant improvement (P < .0001). In addition, participants improved on some other cognitive measures, and Dr. Christensen noted that “significant improvement was also observed in the patients’ health-related quality of life and daily functioning.”
A third of patients had drug-related treatment-emergent adverse events.
Vortioxetine is one of the most expensive antidepressants: It has a list price of $444 a month, and no generic version is currently available.
Small trial, open-label design
In a comment, Claire Sexton, DPhil, senior director of scientific programs and outreach at the Alzheimer’s Association, said the study “reflects a valuable aspect of treatment research because of the close connection between depression and dementia. Depression is a known risk factor for dementia, including Alzheimer’s disease, and those who have dementia may experience depression.”
She cautioned, however, that the trial was small and had an open-label design instead of the “gold standard” of a double-blinded trial with a control group.
The study was funded by Lundbeck, where Dr. Christensen is an employee. Another author is a Lundbeck employee, and a third author reported various disclosures. Dr. Sexton reported no disclosures.

Mind the geriatrician gap
These should be the best of times for geriatric medicine.
The baby boom has become a senior surge, bringing in a rapidly growing pool of aging patients for geriatricians to treat. According to the U.S. Census Bureau, more than 56 million adults aged 65 and older live in the United States. They account for about 17% of the nation’s population. That number is expected to hit 73 million by 2030 and 86 million by 2050.
The American Geriatrics Society estimates that 30% of older people require the attention of geriatricians. These clinicians excel in managing complex cases – patients with multiple comorbidities, such as coronary artery disease, dementia, and osteoporosis, who are taking a half dozen, and often more, medications.
. In the 2010s, geriatricians called for “25,000 [such specialists] by 2025.” As of 2021, 7123 certified geriatricians were practicing in the United States, according to the American Board of Medical Specialties.
The Health Resources and Services Administration, a federal agency that addresses medical workforce shortages, estimates that there will be 6,230 geriatricians by 2025, or approximately 1 for every 3,000 older adults requiring geriatric care. HRSA projects a shortage of 27,000 geriatricians by 2025.
The specialty has faced an uphill battle to attract fellows. This year, only 43% of the nation’s 177 geriatrics fellowship slots were filled, according to November’s National Resident Match Program report. Family medicine–based geriatrics achieved only a 32% fill rate, while internal medicine–based programs saw a rate of 45%.
“Our numbers are shrinking so we need another approach to make sure older adults get the care they need and deserve,” said G. Michael Harper, MD, president of the 6,000-member AGS.
But Dr. Harper, who practices at the University of California, San Francisco, and the San Francisco VA Medical Center, added a positive note: “We may be struggling to increase the number of board-certified geriatricians, but the field itself has made a lot of progress in terms of improving clinical care through advancements in science and in the ways we deliver care.”
Dr. Harper cited the Hospital Elder Life Program, a hospital model developed at the Harvard-affiliated Marcus Institute for Aging Research, which uses an interprofessional team and trained volunteers to prevent delirium and functional decline. HELP has been adopted by more than 200 hospitals worldwide and has been successful at returning older adults to their homes or previous living situations with maintained or improved ability to function, he said.
Mark Supiano, MD, professor and chief of geriatrics at the University of Utah, Salt Lake City, said the specialty has been in shortage mode since ABMS recognized it in 1988. He was in the initial cohort of fellowship-trained geriatricians, sitting for the first certifying exam in geriatrics offered that year.
“Back then, the demographic imperative of the aging of our society was on the horizon. We’re living it now. I knew enough to recognize it was coming and saw an opportunity,” Dr. Supiano said in an interview. “There was so much then that we didn’t know about how to understand aging or how to care for older adults that there really was such a knowledge gap.”
Dr. Supiano is an associate editor of Hazzard’s Geriatric Medicine and Gerontology (McGraw-Hill Education), which has more than doubled in pages and word count during his career.
Unfavorable finances
Katherine Thompson, MD, director of the geriatrics fellowship program at the University of Chicago and codirector of UChicago’s Successful Aging and Frailty Evaluation Clinic, said money is a major reason for the struggle. “I think probably the biggest driver is financial,” she said. “A lot of people are graduating medical school with really astronomical amounts of medical school loans.”
Geriatricians, like other doctors, carry a large debt – $200,000, on average, not counting undergraduate debt, according to the Association of American Medical Colleges.
But the typical geriatrician earns less than an internist or family medicine doctor who doesn’t undergo the additional year of training, Dr. Thompson said. “There’s not a lot of financial motivation to do this fellowship,” she said.
The jobs website Zippia reports that geriatricians earned roughly $165,000 per year on average in 2022. The average annual incomes in 2022 were $191,000 for pediatricians, $215,000 for family physicians, and $223,000 for internists, according to the site.
In other words, Dr. Harper said, “geriatrics is one of the few professions where you can actually do additional training and make less money.”
The reason for the pay issue is simple: Geriatricians treat patients covered by Medicare, whose reimbursement schedules lag behind those of commercial insurers. The Kaiser Family Foundation reported in 2020 that private insurance paid 143% of Medicare rates on average for physician services.
Dr. Harper said overall compensation for geriatricians has “not gained a lot of traction,” but they can earn comfortable livings.
Still, representation of the specialty on the American Medical Association’s Relative Value Scale Update Committee has led to approval by the Centers for Medicare & Medicaid Services of billing codes that pay geriatricians “for what they do. Examples include chronic care management, advance care planning, and dementia evaluation,” he said.
But the geriatrician gap goes beyond money.
Ageism, too, may play a role in residents not choosing geriatrics.
“Our culture is ageist. It definitely focuses on youth and looks at aging as being loss rather than just a change in what works well and what doesn’t work well,” said Mary Tinetti, MD, a geriatrician and researcher at Yale University, New Haven, Conn. “Ageism happens among physicians, just because they’re part of the broader society.”
Time for a new goal?
Dr. Tinetti said she’s optimistic that new ideas about geriatricians teaching other primary care clinicians about the tenets of geriatric medicine, which offer a wholistic approach to comorbidities, such as diabetes, atrial fibrillation, dementia, hypertension, hyperlipidemia, and polypharmacy problems faced by this population, especially those 85 and older.
She has called on her profession to abandon the goal of increasing the numbers of board-certified geriatricians – whom she refers to as big “G” geriatricians. She instead wants to develop a “small, elite workforce” that discovers and tests geriatrics principles through research, teaches these principles to all healthcare professions and to the public, and disseminates and implements the policies.
“We need a cadre of geriatricians who train all other clinicians in the care of older adults,” Dr. Tinetti said. “The goal is not more geriatricians but rather the preparation of all clinicians in the care of older adults.”
Dr. Thompson said geriatricians are teaching primary care specialists, nurses, social workers, and other health care providers the principles of age-friendly care. AGS has for the past 20 years led a program called the Geriatrics for Specialists Initiative to increase geriatrics knowledge and expertise of surgical and medical specialists.
Some specialties have taken the cue and have added geriatrics-related hyphens through additional training: geriatric-emergency, geriatric-general surgery, geriatric-hospitalists, and more.
HRSA runs programs to encourage physicians to train as geriatricians and geriatrics faculty, and it encourages the geriatrics interdisciplinary team approach.
Richard Olague, director of public affairs for HRSA, said his agency has invested over $160 million over the past 4 years in the education and training of geriatricians and other health care professionals who care for the elderly through its Geriatrics Workforce Enhancement Program and Geriatrics Academic Career Awards Program. In the academic year 2020-2021, the two programs trained 109 geriatricians; 456 other geriatric/gerontology providers and students; 44,450 other healthcare workforce professionals and students; and served 17,666 patients and 5,409 caregivers.
Dr. Harper, like his fellow geriatricians, tells young doctors that geriatrics is a fulfilling specialty.
“I get to care for the whole person and sometimes their families, too, and in the process form rich and meaningful relationships. And while I’m rarely in the position to cure, I always have the ability to care,” he said. “Sometimes that can mean being an advocate trying to make sure my patients receive the care they need, and other times it might mean protecting them from burdensome care that is unlikely to lead to any meaningful benefit. There is great reward in all of that.”
Dr. Supiano said geriatric patients are being helped by the Age-Friendly Health System initiative of the John A. Hartford Foundation and the Institute for Healthcare Improvement in partnership with the American Hospital Association and the Catholic Health Association of the United States. This is sort of a seal of approval for facilities committed to age-friendly care.
“When you go to your hospital, if they don’t have this age-friendly health system banner on the front door ... you either ask why that is not there, or you vote with your feet and go to another health system that is age friendly,” he said. “Geriatricians are eternal optimists.”

Ultraprocessed foods tied to faster rate of cognitive decline
Results from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil), which included more than 10,000 people aged 35 and older, showed that higher intake of UPF was significantly associated with a faster rate of decline in executive and global cognitive function.
“These findings show that lifestyle choices, particularly high intake of ultraprocessed foods, can influence our cognitive health many years later,” coinvestigator Natalia Goncalves, PhD, University of São Paulo, Brazil, said in an interview.
The study was published online in JAMA Neurology.
The study’s findings were presented in August at the Alzheimer’s Association International Conference (AAIC) 2022 and were reported by this news organization at that time.
High sugar, salt, fat
The new results align with another recent study linking a diet high in UPFs to an increased risk for dementia.
UPFs are highly manipulated, are packed with added ingredients, including sugar, fat, and salt, and are low in protein and fiber. Examples of UPFs are soft drinks, chips, chocolate, candy, ice cream, sweetened breakfast cereals, packaged soups, chicken nuggets, hot dogs, and fries.
The ELSA-Brasil study comprised 10,775 adults (mean age, 50.6 years at baseline; 55% women; 53% White) who were evaluated in three waves approximately 4 years apart from 2008 to 2017.
Information on diet was obtained via food frequency questionnaires and included details regarding consumption of unprocessed foods, minimally processed foods, and UPFs.
Participants were grouped according to UPF consumption quartiles (lowest to highest). Cognitive performance was evaluated by use of a standardized battery of tests.
During median follow-up of 8 years, people who consumed more than 20% of daily calories from UPFs (quartiles 2-4) experienced a 28% faster rate of decline in global cognition (beta = –0.004; 95% confidence interval [CI], –0.006 to –0.001; P = .003) and a 25% faster rate of decline in executive function (beta = –0.003, 95% CI, –0.005 to 0.000; P = .01) compared to peers in quartile 1 who consumed less than 20% of daily calories from UPFs.
The researchers did not investigate individual groups of UPFs.
However, Dr. Goncalves noted that some studies have linked the consumption of sugar-sweetened beverages with lower cognitive performance, lower brain volume, and poorer memory performance. Another group of ultraprocessed foods, processed meats, has been associated with increased all-cause dementia and Alzheimer’s disease.
Other limitations include the fact that self-reported diet habits were assessed only at baseline using a food frequency questionnaire that was not designed to assess the degree of processing.
While analyses were adjusted for several sociodemographic and clinical confounders, the researchers said they could not exclude the possibility of residual confounding.
Also, since neuroimaging is not available in the ELSA-Brasil study, they were not able to investigate potential mechanisms that could explain the association between higher UPF consumption and cognitive decline.
Despite these limitations, the researchers said their findings suggest that “limiting UPF consumption, particularly in middle-aged adults, may be an efficient form to prevent cognitive decline.”
Weighing the evidence
Several experts weighed in on the results in a statement from the UK nonprofit organization, Science Media Centre.
Kevin McConway, PhD, with Open University, Milton Keynes, England, said it’s important to note that the study suggests “an association, a correlation, and that doesn’t necessarily mean that the cognitive decline was caused by eating more ultra-processed foods.”
He also noted that some types of cognitive decline that are associated with aging occurred in participants in all four quartiles, which were defined by the percentage of their daily energy that came from consuming UPFs.
“That’s hardly surprising – it’s a sad fact of life that pretty well all of us gradually lose some of our cognitive functions as we go through middle and older age,” Dr. McConway said.
“The study doesn’t establish that differences in speed of cognitive decline are caused by ultra-processed food consumption anyway. That’s because it’s an observational study. If the consumption of ultra-processed food causes the differences in rate of cognitive decline, then eating less of it might slow cognitive decline, but if the cause is something else, then that won’t happen,” Dr. McConway added.
Gunter Kuhnle, PhD, professor of nutrition and food science, University of Reading, England, noted that UPFs have become a “fashionable term to explain associations between diet and ill health, and many studies have attempted to show associations.
“Most studies have been observational and had a key limitation: It is very difficult to determine ultra-processed food intake using methods that are not designed to do so, and so authors need to make a lot of assumptions. Bread and meat products are often classed as ‘ultra-processed,’ even though this is often wrong,” Dr. Kuhnle noted.
“The same applies to this study – the method used to measure ultra-processed food intake was not designed for that task and relied on assumptions. This makes it virtually impossible to draw any conclusions,” Dr. Kuhnle said.
Duane Mellor, PhD, RD, RNutr, registered dietitian and senior teaching fellow, Aston University, Birmingham, England, said the study does not change how we should try to eat to maintain good brain function and cognition.
“We should try to eat less foods which are high in added sugar, salt, and fat, which would include many of the foods classified as being ultra-processed, while eating more in terms of both quantity and variety of vegetables, fruit, nuts, seeds, and pulses, which are known to be beneficial for both our cognitive and overall health,” Dr. Mellor said.
The ELSA-Brasil study was supported by the Brazilian Ministry of Health, the Ministry of Science, Technology and Innovation, and the National Council for Scientific and Technological Development. The authors as well as Dr. McConway, Dr. Mellor, and Dr. Kuhnle have disclosed no relevant financial relationships.

Results from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil), which included more than 10,000 people aged 35 and older, showed that higher intake of UPF was significantly associated with a faster rate of decline in executive and global cognitive function.
“These findings show that lifestyle choices, particularly high intake of ultraprocessed foods, can influence our cognitive health many years later,” coinvestigator Natalia Goncalves, PhD, University of São Paulo, Brazil, said in an interview.
The study was published online in JAMA Neurology.
The study’s findings were presented in August at the Alzheimer’s Association International Conference (AAIC) 2022 and were reported by this news organization at that time.
High sugar, salt, fat
The new results align with another recent study linking a diet high in UPFs to an increased risk for dementia.
UPFs are highly manipulated, are packed with added ingredients, including sugar, fat, and salt, and are low in protein and fiber. Examples of UPFs are soft drinks, chips, chocolate, candy, ice cream, sweetened breakfast cereals, packaged soups, chicken nuggets, hot dogs, and fries.
The ELSA-Brasil study comprised 10,775 adults (mean age, 50.6 years at baseline; 55% women; 53% White) who were evaluated in three waves approximately 4 years apart from 2008 to 2017.
Information on diet was obtained via food frequency questionnaires and included details regarding consumption of unprocessed foods, minimally processed foods, and UPFs.
Participants were grouped according to UPF consumption quartiles (lowest to highest). Cognitive performance was evaluated by use of a standardized battery of tests.
During median follow-up of 8 years, people who consumed more than 20% of daily calories from UPFs (quartiles 2-4) experienced a 28% faster rate of decline in global cognition (beta = –0.004; 95% confidence interval [CI], –0.006 to –0.001; P = .003) and a 25% faster rate of decline in executive function (beta = –0.003, 95% CI, –0.005 to 0.000; P = .01) compared to peers in quartile 1 who consumed less than 20% of daily calories from UPFs.
The researchers did not investigate individual groups of UPFs.
However, Dr. Goncalves noted that some studies have linked the consumption of sugar-sweetened beverages with lower cognitive performance, lower brain volume, and poorer memory performance. Another group of ultraprocessed foods, processed meats, has been associated with increased all-cause dementia and Alzheimer’s disease.
Other limitations include the fact that self-reported diet habits were assessed only at baseline using a food frequency questionnaire that was not designed to assess the degree of processing.
While analyses were adjusted for several sociodemographic and clinical confounders, the researchers said they could not exclude the possibility of residual confounding.
Also, since neuroimaging is not available in the ELSA-Brasil study, they were not able to investigate potential mechanisms that could explain the association between higher UPF consumption and cognitive decline.

FROM JAMA NEUROLOGY
Confirmed: Amyloid, tau levels rise years before Alzheimer’s onset
“Our results confirm accelerated biomarker changes during preclinical AD and highlight the important role of amyloid levels in tau accelerations,” the investigators note.
“These data may suggest that there is a short therapeutic window for slowing AD pathogenesis prior to the emergence of clinical symptoms – and that this window may occur after amyloid accumulation begins but before amyloid has substantial impacts on tau accumulation,” study investigator Corinne Pettigrew, PhD, department of neurology, Johns Hopkins University School of Medicine, Baltimore, told this news organization.
The study was published online in Alzheimer’s and Dementia.
Novel long-term CSF data
The study builds on previous research by examining changes in cerebrospinal fluid (CSF) biomarkers over longer periods than had been done previously, particularly among largely middle-aged and cognitively normal at baseline individuals.
The researchers examined changes in amyloid beta (Aβ) 42/Aβ40, phosphorylated tau181 (p-tau181), and total tau (t-tau) in CSF over an average of 10.7 years (and up to 23 years) among 278 individuals who were largely middle-aged persons who were cognitively normal at baseline.
“To our knowledge, no prior study among initially cognitively normal, primarily middle-aged individuals has described CSF AD biomarker changes over this duration of follow-up,” the researchers write.
During follow-up, 94 individuals who initially had normal cognition developed mild cognitive impairment (MCI).
Lower baseline levels of amyloid were associated with greater increases in tau (more strongly in men than women), while accelerations in tau were more closely linked to onset of MCI, the researchers report.
Among individuals who developed MCI, biomarker levels were more abnormal and tau increased to a greater extent prior to the onset of MCI symptoms, they found.
Clear impact of APOE4
The findings also suggest that among APOE4 carriers, amyloid onset occurs at an earlier age and rates of amyloid positivity are higher, but there are no differences in rates of change in amyloid over time.
“APOE4 genetic status was not related to changes in CSF beta-amyloid after accounting for the fact that APOE4 carriers have higher rates of amyloid positivity,” said Dr. Pettigrew.
“These findings suggest that APOE4 genetic status shifts the age of onset of amyloid accumulation (with APOE4 carriers having an earlier age of onset compared to non-carriers), but that APOE4 is not related to rates of change in CSF beta-amyloid over time,” she added.
“Thus, cognitively normal APOE4 carriers may be in more advanced preclinical AD stages at younger ages than individuals who are not APOE4 carriers, which is likely relevant for optimizing clinical trial recruitment strategies,” she said.
Funding for the study was provided by the National Institutes of Health. Dr. Pettigrew has disclosed no relevant financial relationships. The original article contains a complete list of author disclosures.

FROM ALZHEIMER’S AND DEMENTIA
Resilience and mind-body interventions in late-life depression
Resilience has been defined as the ability to adapt and thrive in the face of adversity, acute stress, or trauma.1 Originally conceived as an inborn trait characteristic, resilience is now conceptualized as a dynamic, multidimensional capacity influenced by the interactions between internal factors (eg, personality, cognitive capacity, physical health) and environmental resources (eg, social status, financial stability).2,3 Resilience in older adults (typically defined as age ≥65) can improve the prognosis and outcomes for physical and mental conditions.4 The construct is closely aligned with “successful aging” and can be fostered in older adults, leading to improved physical and mental health and well-being.5
While initially resilience was conceptualized as the opposite of depressive states, recent research has identified resilience in the context of major depressive disorder (MDD) as the net effects of various psychosocial and biological variables that decrease the risk of onset, relapse, or depressive illness severity and increase the probability or speed of recovery.6 Late-life depression (LLD) in adults age >65 is a common and debilitating disease, often leading to decreased psychological well-being, increased cognitive decline, and excess mortality.7,8 LLD is associated with several factors, such as cerebrovascular disease, neurodegenerative disease, and inflammation, all of which could contribute to brain vulnerability and an increased risk of depression.9 Physical and cognitive engagement, physical activity, and high brain reserve have been shown to confer resilience to affective and cognitive changes in older adults, despite brain vulnerability.9
The greatest levels of resilience have been observed in individuals in their fifth decade of life and later,4,10 with high levels of resilience significantly contributing to longevity5; however, little is known about which factors contribute to heterogeneity in resilience characteristics and outcomes.4 Furthermore, the concept of resilience continues to raise numerous questions, including:
- how resilience should be measured or defined
- what factors promote or deter the development of resilience
- the effects of resilience on various health and psychological outcomes
- which interventions are effective in enhancing resilience in older adults.4
In this article, we describe resilience in older adults with LLD, its clinical and neurocognitive correlates, and underlying neurobiological and immunological biomarkers. We also examine resilience-building interventions, such as mind-body therapies (MBTs), that have been shown to enhance resilience by promoting positive perceptions of difficult experiences and challenges.
Clinical and neurocognitive correlates of resilience
Resilience varies substantially among older adults with LLD as well as across the lifespan of an individual.11 Identifying clinical components and predictors of resilience may usefully inform the development and testing of interventions to prevent and treat LLD.11 One tool widely used to measure resilience—the self-report Connor-Davidson Resilience Scale (CD-RISC)12— has been found to have clinically relevant characteristics.1,11 Using data from 337 older adults with LLD, Laird et al11 performed an exploratory factor analysis of the CD-RISC and found a 4-factor model:
- grit
- adaptive coping self-efficacy
- accommodative coping self-efficacy
- spirituality.1,11
Having a strong sense of purpose and not being easily discouraged by failure were items characteristic of grit.1,11 The preference to take the lead in problem-solving was typical of items loading on adaptive coping self-efficacy, while accommodative coping self-efficacy measured flexibility, cognitive reframing, a sense of humor, and acceptance in the face of uncontrollable stress.1,11 Finally, the belief that “things happen for a reason” and that “sometimes fate or God can help me” are characteristics of spirituality. 1,11 Using a multivariate model, the greatest variance in total resilience scores was explained by less depression, less apathy, higher quality of life, non-White race, and, somewhat counterintuitively, greater medical comorbidity.1,11 Thus, interventions designed to help older adults cultivate grit, active coping, accommodative coping, and spirituality may enhance resilience in LLD.
Resilience may also be positively associated with cognitive functioning and could be neuroprotective in LLD.13 Laird et al13 investigated associations between baseline resilience and several domains of neurocognitive functioning in 288 older adults with LLD. Several positive associations were found between measured language performance and total resilience, active coping, and accommodative coping.13 Additionally, total resilience and accommodative coping were significantly associated with a lower self-reported frequency of forgetfulness, a subjective measure of memory used in this study.13 Together, these results suggest that interventions targeting language might be useful to improve coping in LLD.13 Another interesting finding was that the resilience subdomain of spirituality was negatively associated with memory, language, and executive functioning performance.13 A distinction must be made between religious attendance (eg, regular attendance at religious institutions) vs religious beliefs, which may account for the previously reported associations between spirituality and improved cognition.13
Continue to: Self-reported resilience...
Self-reported resilience may also predict greater responsivity to antidepressant medication in patients with LLD.14 Older adults with LLD and greater self-reported baseline resilience were more likely to experience improvement or remission from depression with antidepressant treatment.14 This is congruent with conceptualizations of resilience as “the ability to adapt to and recover from stress.”14,15 Of the 4 identified resilience factors (grit, adaptive coping, accommodative coping, and spirituality), it appears that accommodative coping predicts LLD treatment response and remission.14 The unique ability to accommodate is associated with better mental health outcomes in the face of uncontrollable stress.14,16-18 Older adults appear to engage in more accommodative coping due to frequent uncontrollable stress and aging-related physiological changes (eg, sleep changes, chronic pain, declining cognition). This could make accommodative coping especially important in this population.14,19
The Figure, adapted from Weisenbach et al,9 exhibits factors that contribute to LLD, including cerebrovascular disease, neurodegeneration, and chronic inflammation, all of which can lead to a vulnerable aging brain that is at higher risk for depression, particularly within the context of stress. Clinical and neurocognitive factors associated with resilience can help buffer vulnerable brains from developing depression.
Neurobiological biomarkers of resilience in LLD
Gross anatomical indicators: Findings from neuroimaging
The neurobiology underlying psychological resilience involves brain networks associated with stress response, negative affect, and emotional control.19 Increased amygdala reactivity and amygdala frontal connectivity are often implicated in neurobiological models of resilience.20 Leaver et al20 correlated psychological resilience measures with amygdala function in 48 depressed vs nondepressed individuals using functional magnetic resonance imaging. Specifically, they targeted the basolateral, centromedial, and superficial nuclei groups of the amygdala while comparing the 2 groups based on resilience scores (CD-RISC), depressive symptom severity, and depression status.20 A significant correlation was identified between resilience and connectivity between the superficial group of amygdala nuclei and the ventral default mode network (VDMN).20 High levels of psychological resilience were associated with lower basal amygdala activity and decreased connectivity between amygdala nuclei and the VDMN.20 Additionally, lower depressive symptoms were associated with higher connectivity between the amygdalae and the dorsal frontal networks.20 These results suggest a complex relationship between amygdala activity, dorsal frontal regions, resilience, and LLD.20
Vlasova et al21 further addressed the multifactorial character of psychological resilience. The associations between the 4 factors of resilience and the regional integrity of white matter in older adults with LLD were examined using diffusion-weighted MRI.21 Grit was found to be associated with greater white matter integrity in the genu of the corpus callosum and cingulum bundle in LLD.21 There was also a positive association between grit and fractional anisotropy (FA) in the callosal region connecting the prefrontal cortex and FA in the cingulum fibers.21 However, results regarding the FA in the cingulum fibers did not survive correction for multiple comparisons and should be considered with caution, pending further research.21
Continue to: Stress response biomarkers of resilience
Stress response biomarkers of resilience
Stress response biomarkers include endocrine, immune, and inflammatory indices. Stress has been identified as a factor in inflammatory responses. Stress-related overstimulation of the HPA axis may increase the risk of LLD.22 Numerous studies have demonstrated an association between increased levels of peripheral proinflammatory cytokines and depressive symptoms in older adults.23 Interleukin-6 (IL-6) has been increasingly linked with depressive symptoms and poor memory performance in older adults.9 There also appears to be an interaction of inflammatory and vascular processes predisposing to LLD, as increased levels of IL-6 and C-reactive protein have been associated with higher white matter pathology.9 Additionally, proinflammatory cytokines impact monoamine neurotransmitter pathways, leading to a reduction in tryptophan and serotonin synthesis, disruption of glucocorticoid receptors, and a decrease in hippocampal neurotrophic support.9 Alexopoulos et al24 further explain that a prolonged CNS immune response can affect emotional and cognitive network functions related to LLD and has a role in the etiology of depressive symptoms in older adults.
Cardiovascular comorbidity and autonomic nervous system dysfunction
Many studies have revealed evidence of a bidirectional association between cardiovascular disease and depression.25 Dysregulation of the autonomic nervous system (ANS) is an underlying mechanism that could explain the link between cardiovascular risk and MDD via heart rate variability (HRV), though research examining age-related capacities provide conflicting data.25,26 HRV is a surrogate index of resting cardiac vagal outflow that represents the ability of the ANS to adapt to psychological, social, and physical environmental changes.27 Higher overall HRV is associated with greater self-regulating capacity, including behavioral, cognitive, and emotional control.28 Additionally, higher HRV may serve as a biomarker of resilience to the development of stress-related disorders such as MDD. Recent studies have shown an overall reduction in HRV in older adults with LLD.29 When high- and low-frequency HRV were investigated separately, only low-frequency HRV was significantly reduced in patients with depression.29 One explanation is that older adults with depression have impaired or reduced baroreflex sensitivity and gain, which is often associated with an increased risk of mortality following cardiac events.30 More research is needed to examine the complex processes required to better characterize the correlation between resilience in cardiovascular disease and autonomic dysfunction.
The Box6,31,32 describes the relationship between markers of cellular health and resilience.
Box
Among the biomarkers of resilience, telomere length and telomerase activity serve as biomarkers of biological aging that can differ from the chronological age and mark successful anti-aging, stress-reducing strategies.31 Telomerase, the cellular enzyme that regulates the health of cells when they reproduce (preserving the telomeres, repetitive DNA strands at the ends of chromosomes), is associated with overall cell health and cellular biological age.31 When telomerase is reduced, the telomeres in a cell are clipped, causing the cells to age more rapidly as the telomeres get shorter through the process of cellular reproduction.31 Psychological stress may play a significant role in telomerase production and subsequent telomere length.32 Lavretsky et al32 evaluated the effect of brief daily yogic meditation on depressive symptoms and immune cell telomerase activity in a family of dementia caregivers with mild depressive symptoms. Brief daily meditation practice led to significant lower levels of depressive symptoms that was accompanied by an increase in telomerase activity, suggesting improvement in stress-induced cellular aging.6,32
Mind-body therapies
There is increasing interest in improving older adults’ physical and emotional well-being while promoting resilience through stress-reducing lifestyle interventions such as MBTs.33 Because MBTs are often considered a natural and safer option compared to conventional medicine, these interventions are rapidly gaining popularity in the United States.33,34 According to a 2017 National Health Survey, there were 5% to 10% increases in the use of yoga, meditation, and chiropractic care from 2012 to 2017, with growing evidence supporting MBTs as minimally invasive, cost-effective approaches for managing stress and neurocognitive disorders.35 In contrast to pharmacologic approaches, MBTs can be used to train individuals to self-regulate in the face of adversity and stress, thus increasing their resilience.
MBTs can be divided into mindful movement exercises and meditative practices. Mindful movement exercises include yoga, tai chi, and qigong. Meditative practices that do not include movement include progressive relaxation, mindfulness, meditation, and acceptance therapies. On average, both mindful movement exercise (eg, yoga) and multicomponent mindfulness-based interventions (eg, mindfulness-based cognitive therapy, mindfulness-based stress reduction [MBSR], and mindfulness-based relapse prevention) can be as effective as other active treatments for psychiatric disorders such as MDD, anxiety, and substance use disorders.36,37 MBSR specifically has been shown to increase empathy, self-control, self-compassion, relationship quality, mindfulness, and spirituality as well as decrease rumination in healthy older adults.38 This suggests that MBSR can help strengthen the 4 factors of resilience.

Research has also begun to evaluate the neurobiological mechanisms by which meditative therapies enhance resilience in mental health disorders, and several promising mechanistic domains (neural, hormonal, immune, cellular, and cardiovascular) have been identified.39 The physical yoga discipline includes asanas (postures), pranayama (breathing techniques), and dhyana (meditation). With the inclusion of mindfulness training, yoga involves the practice of meditation as well as the dynamic combination of proprioceptive and interoceptive awareness, resulting in both attention and profound focus.40 Dedicated yoga practice allows an individual to develop skills to withdraw the senses (pratyahara), concentrate the mind (dharana), and establish unwavering awareness (dhyana).41 The physical and cognitive benefits associated with yoga and mindfulness may be due to mechanisms including pranayama and activation of the parasympathetic nervous system; meditative or contemplative practices; increased body perception; stronger functional connectivity within the basal ganglia; or neuroplastic effects of increased grey matter volume and amygdala with regional enlargement.41 The new learning aspect of yoga practice may contribute to enhancing or improving various aspects of cognition, although the mechanisms are yet to be clarified.
Continued research in this area will promote the integration of MBTs into mainstream clinical practice and help alleviate the increased chronic health burden of an aging population. In the face of the COVID-19 pandemic, public interest in improving resilience and mental health42 can be supported by MBTs that can improve coping with the stress of the pandemic and enhance critical organ function (eg, lungs, heart, brain).43,44 As a result of these limitations, many resources and health care services have used telehealth and virtual platforms to adapt to these challenges and continue offering MBTs.45
Enhancing resilience to improve clinical outcomes
Increasing our understanding of clinical, neurocognitive, and neurobiological markers of resilience in older adults with and without depression could inform the development of interventions that treat and prevent mood and cognitive disorders of aging. Furthermore, stress reduction, decreased inflammation, and improved emotional regulation may have direct neuroplastic effects on the brain, leading to greater resilience. Complementary use of MBTs combined with standard antidepressant treatment may allow for additional improvement in clinical outcomes of LLD, including resilience, quality of life, general health, and cognitive function. Additional research testing the efficacy of those interventions designed to improve resilience in older adults with mood and mental disorders is needed.
Bottom Line
Identifying the clinical, neurocognitive, and neurobiological biomarkers of resilience in late-life depression could aid in the development of targeted interventions that treat and prevent mood and cognitive disorders of aging. Mind-body interventions can help boost resilience and improve outcomes in geriatric patients with mood and cognitive disorders.

Resilience has been defined as the ability to adapt and thrive in the face of adversity, acute stress, or trauma.1 Originally conceived as an inborn trait characteristic, resilience is now conceptualized as a dynamic, multidimensional capacity influenced by the interactions between internal factors (eg, personality, cognitive capacity, physical health) and environmental resources (eg, social status, financial stability).2,3 Resilience in older adults (typically defined as age ≥65) can improve the prognosis and outcomes for physical and mental conditions.4 The construct is closely aligned with “successful aging” and can be fostered in older adults, leading to improved physical and mental health and well-being.5
While initially resilience was conceptualized as the opposite of depressive states, recent research has identified resilience in the context of major depressive disorder (MDD) as the net effects of various psychosocial and biological variables that decrease the risk of onset, relapse, or depressive illness severity and increase the probability or speed of recovery.6 Late-life depression (LLD) in adults age >65 is a common and debilitating disease, often leading to decreased psychological well-being, increased cognitive decline, and excess mortality.7,8 LLD is associated with several factors, such as cerebrovascular disease, neurodegenerative disease, and inflammation, all of which could contribute to brain vulnerability and an increased risk of depression.9 Physical and cognitive engagement, physical activity, and high brain reserve have been shown to confer resilience to affective and cognitive changes in older adults, despite brain vulnerability.9
The greatest levels of resilience have been observed in individuals in their fifth decade of life and later,4,10 with high levels of resilience significantly contributing to longevity5; however, little is known about which factors contribute to heterogeneity in resilience characteristics and outcomes.4 Furthermore, the concept of resilience continues to raise numerous questions, including:
- how resilience should be measured or defined
- what factors promote or deter the development of resilience
- the effects of resilience on various health and psychological outcomes
- which interventions are effective in enhancing resilience in older adults.4
In this article, we describe resilience in older adults with LLD, its clinical and neurocognitive correlates, and underlying neurobiological and immunological biomarkers. We also examine resilience-building interventions, such as mind-body therapies (MBTs), that have been shown to enhance resilience by promoting positive perceptions of difficult experiences and challenges.
Clinical and neurocognitive correlates of resilience
Resilience varies substantially among older adults with LLD as well as across the lifespan of an individual.11 Identifying clinical components and predictors of resilience may usefully inform the development and testing of interventions to prevent and treat LLD.11 One tool widely used to measure resilience—the self-report Connor-Davidson Resilience Scale (CD-RISC)12— has been found to have clinically relevant characteristics.1,11 Using data from 337 older adults with LLD, Laird et al11 performed an exploratory factor analysis of the CD-RISC and found a 4-factor model:
- grit
- adaptive coping self-efficacy
- accommodative coping self-efficacy
- spirituality.1,11
Having a strong sense of purpose and not being easily discouraged by failure were items characteristic of grit.1,11 The preference to take the lead in problem-solving was typical of items loading on adaptive coping self-efficacy, while accommodative coping self-efficacy measured flexibility, cognitive reframing, a sense of humor, and acceptance in the face of uncontrollable stress.1,11 Finally, the belief that “things happen for a reason” and that “sometimes fate or God can help me” are characteristics of spirituality. 1,11 Using a multivariate model, the greatest variance in total resilience scores was explained by less depression, less apathy, higher quality of life, non-White race, and, somewhat counterintuitively, greater medical comorbidity.1,11 Thus, interventions designed to help older adults cultivate grit, active coping, accommodative coping, and spirituality may enhance resilience in LLD.
Resilience may also be positively associated with cognitive functioning and could be neuroprotective in LLD.13 Laird et al13 investigated associations between baseline resilience and several domains of neurocognitive functioning in 288 older adults with LLD. Several positive associations were found between measured language performance and total resilience, active coping, and accommodative coping.13 Additionally, total resilience and accommodative coping were significantly associated with a lower self-reported frequency of forgetfulness, a subjective measure of memory used in this study.13 Together, these results suggest that interventions targeting language might be useful to improve coping in LLD.13 Another interesting finding was that the resilience subdomain of spirituality was negatively associated with memory, language, and executive functioning performance.13 A distinction must be made between religious attendance (eg, regular attendance at religious institutions) vs religious beliefs, which may account for the previously reported associations between spirituality and improved cognition.13
Continue to: Self-reported resilience...
Self-reported resilience may also predict greater responsivity to antidepressant medication in patients with LLD.14 Older adults with LLD and greater self-reported baseline resilience were more likely to experience improvement or remission from depression with antidepressant treatment.14 This is congruent with conceptualizations of resilience as “the ability to adapt to and recover from stress.”14,15 Of the 4 identified resilience factors (grit, adaptive coping, accommodative coping, and spirituality), it appears that accommodative coping predicts LLD treatment response and remission.14 The unique ability to accommodate is associated with better mental health outcomes in the face of uncontrollable stress.14,16-18 Older adults appear to engage in more accommodative coping due to frequent uncontrollable stress and aging-related physiological changes (eg, sleep changes, chronic pain, declining cognition). This could make accommodative coping especially important in this population.14,19
The Figure, adapted from Weisenbach et al,9 exhibits factors that contribute to LLD, including cerebrovascular disease, neurodegeneration, and chronic inflammation, all of which can lead to a vulnerable aging brain that is at higher risk for depression, particularly within the context of stress. Clinical and neurocognitive factors associated with resilience can help buffer vulnerable brains from developing depression.
Neurobiological biomarkers of resilience in LLD
Gross anatomical indicators: Findings from neuroimaging
The neurobiology underlying psychological resilience involves brain networks associated with stress response, negative affect, and emotional control.19 Increased amygdala reactivity and amygdala frontal connectivity are often implicated in neurobiological models of resilience.20 Leaver et al20 correlated psychological resilience measures with amygdala function in 48 depressed vs nondepressed individuals using functional magnetic resonance imaging. Specifically, they targeted the basolateral, centromedial, and superficial nuclei groups of the amygdala while comparing the 2 groups based on resilience scores (CD-RISC), depressive symptom severity, and depression status.20 A significant correlation was identified between resilience and connectivity between the superficial group of amygdala nuclei and the ventral default mode network (VDMN).20 High levels of psychological resilience were associated with lower basal amygdala activity and decreased connectivity between amygdala nuclei and the VDMN.20 Additionally, lower depressive symptoms were associated with higher connectivity between the amygdalae and the dorsal frontal networks.20 These results suggest a complex relationship between amygdala activity, dorsal frontal regions, resilience, and LLD.20
Vlasova et al21 further addressed the multifactorial character of psychological resilience. The associations between the 4 factors of resilience and the regional integrity of white matter in older adults with LLD were examined using diffusion-weighted MRI.21 Grit was found to be associated with greater white matter integrity in the genu of the corpus callosum and cingulum bundle in LLD.21 There was also a positive association between grit and fractional anisotropy (FA) in the callosal region connecting the prefrontal cortex and FA in the cingulum fibers.21 However, results regarding the FA in the cingulum fibers did not survive correction for multiple comparisons and should be considered with caution, pending further research.21
Continue to: Stress response biomarkers of resilience
Stress response biomarkers of resilience
Stress response biomarkers include endocrine, immune, and inflammatory indices. Stress has been identified as a factor in inflammatory responses. Stress-related overstimulation of the HPA axis may increase the risk of LLD.22 Numerous studies have demonstrated an association between increased levels of peripheral proinflammatory cytokines and depressive symptoms in older adults.23 Interleukin-6 (IL-6) has been increasingly linked with depressive symptoms and poor memory performance in older adults.9 There also appears to be an interaction of inflammatory and vascular processes predisposing to LLD, as increased levels of IL-6 and C-reactive protein have been associated with higher white matter pathology.9 Additionally, proinflammatory cytokines impact monoamine neurotransmitter pathways, leading to a reduction in tryptophan and serotonin synthesis, disruption of glucocorticoid receptors, and a decrease in hippocampal neurotrophic support.9 Alexopoulos et al24 further explain that a prolonged CNS immune response can affect emotional and cognitive network functions related to LLD and has a role in the etiology of depressive symptoms in older adults.
Cardiovascular comorbidity and autonomic nervous system dysfunction
Many studies have revealed evidence of a bidirectional association between cardiovascular disease and depression.25 Dysregulation of the autonomic nervous system (ANS) is an underlying mechanism that could explain the link between cardiovascular risk and MDD via heart rate variability (HRV), though research examining age-related capacities provide conflicting data.25,26 HRV is a surrogate index of resting cardiac vagal outflow that represents the ability of the ANS to adapt to psychological, social, and physical environmental changes.27 Higher overall HRV is associated with greater self-regulating capacity, including behavioral, cognitive, and emotional control.28 Additionally, higher HRV may serve as a biomarker of resilience to the development of stress-related disorders such as MDD. Recent studies have shown an overall reduction in HRV in older adults with LLD.29 When high- and low-frequency HRV were investigated separately, only low-frequency HRV was significantly reduced in patients with depression.29 One explanation is that older adults with depression have impaired or reduced baroreflex sensitivity and gain, which is often associated with an increased risk of mortality following cardiac events.30 More research is needed to examine the complex processes required to better characterize the correlation between resilience in cardiovascular disease and autonomic dysfunction.
The Box6,31,32 describes the relationship between markers of cellular health and resilience.
Box
Among the biomarkers of resilience, telomere length and telomerase activity serve as biomarkers of biological aging that can differ from the chronological age and mark successful anti-aging, stress-reducing strategies.31 Telomerase, the cellular enzyme that regulates the health of cells when they reproduce (preserving the telomeres, repetitive DNA strands at the ends of chromosomes), is associated with overall cell health and cellular biological age.31 When telomerase is reduced, the telomeres in a cell are clipped, causing the cells to age more rapidly as the telomeres get shorter through the process of cellular reproduction.31 Psychological stress may play a significant role in telomerase production and subsequent telomere length.32 Lavretsky et al32 evaluated the effect of brief daily yogic meditation on depressive symptoms and immune cell telomerase activity in a family of dementia caregivers with mild depressive symptoms. Brief daily meditation practice led to significant lower levels of depressive symptoms that was accompanied by an increase in telomerase activity, suggesting improvement in stress-induced cellular aging.6,32
Mind-body therapies
There is increasing interest in improving older adults’ physical and emotional well-being while promoting resilience through stress-reducing lifestyle interventions such as MBTs.33 Because MBTs are often considered a natural and safer option compared to conventional medicine, these interventions are rapidly gaining popularity in the United States.33,34 According to a 2017 National Health Survey, there were 5% to 10% increases in the use of yoga, meditation, and chiropractic care from 2012 to 2017, with growing evidence supporting MBTs as minimally invasive, cost-effective approaches for managing stress and neurocognitive disorders.35 In contrast to pharmacologic approaches, MBTs can be used to train individuals to self-regulate in the face of adversity and stress, thus increasing their resilience.
MBTs can be divided into mindful movement exercises and meditative practices. Mindful movement exercises include yoga, tai chi, and qigong. Meditative practices that do not include movement include progressive relaxation, mindfulness, meditation, and acceptance therapies. On average, both mindful movement exercise (eg, yoga) and multicomponent mindfulness-based interventions (eg, mindfulness-based cognitive therapy, mindfulness-based stress reduction [MBSR], and mindfulness-based relapse prevention) can be as effective as other active treatments for psychiatric disorders such as MDD, anxiety, and substance use disorders.36,37 MBSR specifically has been shown to increase empathy, self-control, self-compassion, relationship quality, mindfulness, and spirituality as well as decrease rumination in healthy older adults.38 This suggests that MBSR can help strengthen the 4 factors of resilience.

Enhancing resilience to improve clinical outcomes
Increasing our understanding of clinical, neurocognitive, and neurobiological markers of resilience in older adults with and without depression could inform the development of interventions that treat and prevent mood and cognitive disorders of aging. Furthermore, stress reduction, decreased inflammation, and improved emotional regulation may have direct neuroplastic effects on the brain, leading to greater resilience. Complementary use of MBTs combined with standard antidepressant treatment may allow for additional improvement in clinical outcomes of LLD, including resilience, quality of life, general health, and cognitive function. Additional research testing the efficacy of those interventions designed to improve resilience in older adults with mood and mental disorders is needed.

Mind-body interventions can help boost resilience and improve outcomes in geriatric patients with mood and cognitive disorders.

Several positive associations were found between measured language performance and total resilience, active coping, and accommodative coping.13 Additionally, total resilience and accommodative coping were significantly associated with a lower self-reported frequency of forgetfulness, a subjective measure of memory used in this study.13 Together, these results suggest that interventions targeting language might be useful to improve coping in LLD.13 Another interesting finding was that the resilience subdomain of spirituality was negatively associated with memory, language, and executive functioning performance.13 A distinction must be made between religious attendance (eg, regular attendance at religious institutions) vs religious beliefs, which may account for the previously reported associations between spirituality and improved cognition.13

Self-reported resilience may also predict greater responsivity to antidepressant medication in patients with LLD.14 Older adults with LLD and greater self-reported baseline resilience were more likely to experience improvement or remission from depression with antidepressant treatment.14 This is congruent with conceptualizations of resilience as “the ability to adapt to and recover from stress.”14,15 Of the 4 identified resilience factors (grit, adaptive coping, accommodative coping, and spirituality), it appears that accommodative coping predicts LLD treatment response and remission.14 The unique ability to accommodate is associated with better mental health outcomes in the face of uncontrollable stress.14,16-18 Older adults appear to engage in more accommodative coping due to frequent uncontrollable stress and aging-related physiological changes (eg, sleep changes, chronic pain, declining cognition). This could make accommodative coping especially important in this population.14,19
The Figure, adapted from Weisenbach et al,9 exhibits factors that contribute to LLD, including cerebrovascular disease, neurodegeneration, and chronic inflammation, all of which can lead to a vulnerable aging brain that is at higher risk for depression, particularly within the context of stress. Clinical and neurocognitive factors associated with resilience can help buffer vulnerable brains from developing depression.
Neurobiological biomarkers of resilience in LLD
Gross anatomical indicators: Findings from neuroimaging
The neurobiology underlying psychological resilience involves brain networks associated with stress response, negative affect, and emotional control.19 Increased amygdala reactivity and amygdala frontal connectivity are often implicated in neurobiological models of resilience.20 Leaver et al20 correlated psychological resilience measures with amygdala function in 48 depressed vs nondepressed individuals using functional magnetic resonance imaging. Specifically, they targeted the basolateral, centromedial, and superficial nuclei groups of the amygdala while comparing the 2 groups based on resilience scores (CD-RISC), depressive symptom severity, and depression status.20 A significant correlation was identified between resilience and connectivity between the superficial group of amygdala nuclei and the ventral default mode network (VDMN).20 High levels of psychological resilience were associated with lower basal amygdala activity and decreased connectivity between amygdala nuclei and the VDMN.20 Additionally, lower depressive symptoms were associated with higher connectivity between the amygdalae and the dorsal frontal networks.20 These results suggest a complex relationship between amygdala activity, dorsal frontal regions, resilience, and LLD.20
Vlasova et al21 further addressed the multifactorial character of psychological resilience. The associations between the 4 factors of resilience and the regional integrity of white matter in older adults with LLD were examined using diffusion-weighted MRI.21 Grit was found to be associated with greater white matter integrity in the genu of the corpus callosum and cingulum bundle in LLD.21 There was also a positive association between grit and fractional anisotropy (FA) in the callosal region connecting the prefrontal cortex and FA in the cingulum fibers.21 However, results regarding the FA in the cingulum fibers did not survive correction for multiple comparisons and should be considered with caution, pending further research.21

Stress response biomarkers of resilience
Stress response biomarkers include endocrine, immune, and inflammatory indices. Stress has been identified as a factor in inflammatory responses. Stress-related overstimulation of the HPA axis may increase the risk of LLD.22 Numerous studies have demonstrated an association between increased levels of peripheral proinflammatory cytokines and depressive symptoms in older adults.23 Interleukin-6 (IL-6) has been increasingly linked with depressive symptoms and poor memory performance in older adults.9 There also appears to be an interaction of inflammatory and vascular processes predisposing to LLD, as increased levels of IL-6 and C-reactive protein have been associated with higher white matter pathology.9 Additionally, proinflammatory cytokines impact monoamine neurotransmitter pathways, leading to a reduction in tryptophan and serotonin synthesis, disruption of glucocorticoid receptors, and a decrease in hippocampal neurotrophic support.9 Alexopoulos et al24 further explain that a prolonged CNS immune response can affect emotional and cognitive network functions related to LLD and has a role in the etiology of depressive symptoms in older adults.
Cardiovascular comorbidity and autonomic nervous system dysfunction
Many studies have revealed evidence of a bidirectional association between cardiovascular disease and depression.25 Dysregulation of the autonomic nervous system (ANS) is an underlying mechanism that could explain the link between cardiovascular risk and MDD via heart rate variability (HRV), though research examining age-related capacities provide conflicting data.25,26 HRV is a surrogate index of resting cardiac vagal outflow that represents the ability of the ANS to adapt to psychological, social, and physical environmental changes.27 Higher overall HRV is associated with greater self-regulating capacity, including behavioral, cognitive, and emotional control.28 Additionally, higher HRV may serve as a biomarker of resilience to the development of stress-related disorders such as MDD. Recent studies have shown an overall reduction in HRV in older adults with LLD.29 When high- and low-frequency HRV were investigated separately, only low-frequency HRV was significantly reduced in patients with depression.29 One explanation is that older adults with depression have impaired or reduced baroreflex sensitivity and gain, which is often associated with an increased risk of mortality following cardiac events.30 More research is needed to examine the complex processes required to better characterize the correlation between resilience in cardiovascular disease and autonomic dysfunction.
The Box6,31,32 describes the relationship between markers of cellular health and resilience.

Among the biomarkers of resilience, telomere length and telomerase activity serve as biomarkers of biological aging that can differ from the chronological age and mark successful anti-aging, stress-reducing strategies.31 Telomerase, the cellular enzyme that regulates the health of cells when they reproduce (preserving the telomeres, repetitive DNA strands at the ends of chromosomes), is associated with overall cell health and cellular biological age.31 When telomerase is reduced, the telomeres in a cell are clipped, causing the cells to age more rapidly as the telomeres get shorter through the process of cellular reproduction.31 Psychological stress may play a significant role in telomerase production and subsequent telomere length.32 Lavretsky et al32 evaluated the effect of brief daily yogic meditation on depressive symptoms and immune cell telomerase activity in a family of dementia caregivers with mild depressive symptoms. Brief daily meditation practice led to significant lower levels of depressive symptoms that was accompanied by an increase in telomerase activity, suggesting improvement in stress-induced cellular aging.6,32
Mind-body therapies
There is increasing interest in improving older adults’ physical and emotional well-being while promoting resilience through stress-reducing lifestyle interventions such as MBTs.33 Because MBTs are often considered a natural and safer option compared to conventional medicine, these interventions are rapidly gaining popularity in the United States.33,34 According to a 2017 National Health Survey, there were 5% to 10% increases in the use of yoga, meditation, and chiropractic care from 2012 to 2017, with growing evidence supporting MBTs as minimally invasive, cost-effective approaches for managing stress and neurocognitive disorders.35 In contrast to pharmacologic approaches, MBTs can be used to train individuals to self-regulate in the face of adversity and stress, thus increasing their resilience.
MBTs can be divided into mindful movement exercises and meditative practices. Mindful movement exercises include yoga, tai chi, and qigong. Meditative practices that do not include movement include progressive relaxation, mindfulness, meditation, and acceptance therapies. On average, both mindful movement exercise (eg, yoga) and multicomponent mindfulness-based interventions (eg, mindfulness-based cognitive therapy, mindfulness-based stress reduction [MBSR], and mindfulness-based relapse prevention) can be as effective as other active treatments for psychiatric disorders such as MDD, anxiety, and substance use disorders.36,37 MBSR specifically has been shown to increase empathy, self-control, self-compassion, relationship quality, mindfulness, and spirituality as well as decrease rumination in healthy older adults.38 This suggests that MBSR can help strengthen the 4 factors of resilience.
Continue to: Research has also begun...
Research has also begun to evaluate the neurobiological mechanisms by which meditative therapies enhance resilience in mental health disorders, and several promising mechanistic domains (neural, hormonal, immune, cellular, and cardiovascular) have been identified.39 The physical yoga discipline includes asanas (postures), pranayama (breathing techniques), and dhyana (meditation). With the inclusion of mindfulness training, yoga involves the practice of meditation as well as the dynamic combination of proprioceptive and interoceptive awareness, resulting in both attention and profound focus.40 Dedicated yoga practice allows an individual to develop skills to withdraw the senses (pratyahara), concentrate the mind (dharana), and establish unwavering awareness (dhyana).41 The physical and cognitive benefits associated with yoga and mindfulness may be due to mechanisms including pranayama and activation of the parasympathetic nervous system; meditative or contemplative practices; increased body perception; stronger functional connectivity within the basal ganglia; or neuroplastic effects of increased grey matter volume and amygdala with regional enlargement.41 The new learning aspect of yoga practice may contribute to enhancing or improving various aspects of cognition, although the mechanisms are yet to be clarified.
Continued research in this area will promote the integration of MBTs into mainstream clinical practice and help alleviate the increased chronic health burden of an aging population. In the face of the COVID-19 pandemic, public interest in improving resilience and mental health42 can be supported by MBTs that can improve coping with the stress of the pandemic and enhance critical organ function (eg, lungs, heart, brain).43,44 As a result of these limitations, many resources and health care services have used telehealth and virtual platforms to adapt to these challenges and continue offering MBTs.45
Enhancing resilience to improve clinical outcomes
Increasing our understanding of clinical, neurocognitive, and neurobiological markers of resilience in older adults with and without depression could inform the development of interventions that treat and prevent mood and cognitive disorders of aging. Furthermore, stress reduction, decreased inflammation, and improved emotional regulation may have direct neuroplastic effects on the brain, leading to greater resilience. Complementary use of MBTs combined with standard antidepressant treatment may allow for additional improvement in clinical outcomes of LLD, including resilience, quality of life, general health, and cognitive function. Additional research testing the efficacy of those interventions designed to improve resilience in older adults with mood and mental disorders is needed.
Bottom Line
Identifying the clinical, neurocognitive, and neurobiological biomarkers of resilience in late-life depression could aid in the development of targeted interventions that treat and prevent mood and cognitive disorders of aging. Mind-body interventions can help boost resilience and improve outcomes in geriatric patients with mood and cognitive disorders.

U.S. flu activity already at mid-season levels
according to the Centers of Disease Control and Prevention.
Nationally, 6% of all outpatient visits were because of flu or flu-like illness for the week of Nov. 13-19, up from 5.8% the previous week, the CDC’s Influenza Division said in its weekly FluView report.
Those figures are the highest recorded in November since 2009, but the peak of the 2009-10 flu season occurred even earlier – the week of Oct. 18-24 – and the rate of flu-like illness had already dropped to just over 4.0% by Nov. 15-21 that year and continued to drop thereafter.
Although COVID-19 and respiratory syncytial virus (RSV) are included in the data from the CDC’s Outpatient Influenza-like Illness Surveillance Network, the agency did note that “seasonal influenza activity is elevated across the country” and estimated that “there have been at least 6.2 million illnesses, 53,000 hospitalizations, and 2,900 deaths from flu” during the 2022-23 season.
Total flu deaths include 11 reported in children as of Nov. 19, and children ages 0-4 had a higher proportion of visits for flu like-illness than other age groups.
The agency also said the cumulative hospitalization rate of 11.3 per 100,000 population “is higher than the rate observed in [the corresponding week of] every previous season since 2010-2011.” Adults 65 years and older have the highest cumulative rate, 25.9 per 100,000, for this year, compared with 20.7 for children 0-4; 11.1 for adults 50-64; 10.3 for children 5-17; and 5.6 for adults 18-49 years old, the CDC said.

Nationally, 6% of all outpatient visits were because of flu or flu-like illness for the week of Nov. 13-19, up from 5.8% the previous week, the CDC’s Influenza Division said in its weekly FluView report.

Sarilumab effective for polymyalgia rheumatica in phase 3 trial
PHILADELPHIA – Treatment with the interleukin-6 receptor antagonist sarilumab (Kevzara), along with a 14-week taper of glucocorticoids, proved to have significant efficacy in patients with relapsing polymyalgia rheumatica (PMR) who were resistant to glucocorticoids in a phase 3 trial.
No new safety concerns were found with sarilumab in the multicenter, randomized, double-blind, placebo-controlled SAPHYR trial. Sarilumab is approved in the United States for the treatment of moderate to severe active rheumatoid arthritis in adults who have had an inadequate response or intolerance to one or more disease-modifying antirheumatic drugs.
The results, presented at the annual meeting of the American College of Rheumatology by Robert Spiera, MD, director of the Scleroderma, Vasculitis, and Myositis Center at the Hospital for Special Surgery in New York, included clinically meaningful improvement in quality-of-life scores.
The disease, which primarily affects people over age 65, can cause widespread aching and stiffness. It’s one of the most common inflammatory diseases among older adults.
PMR is relatively easy to treat with glucocorticoids, but relapses are common, which means long courses of glucocorticoid therapy and the side effects that come with them.
Need for a steroid-sparing therapy
“We recognize that a steroid-sparing drug in polymyalgia rheumatica seems to be an unmet need,” Dr. Spiera said at the meeting.
The trial, sponsored by Sanofi, included active, refractory PMR patients who flared within 3 months of study entry while on at least 7.5 mg/day of prednisone or the equivalent. They were randomly assigned (1:1) to 52 weeks of treatment with subcutaneous sarilumab 200 mg every 2 weeks plus the rapid 14-week glucocorticoid tapering regimen or were given placebo every 2 weeks plus a more traditional 52-week tapering of glucocorticoids.
COVID hampered recruitment
Recruitment was stopped early because of complications during the COVID-19 pandemic, so between October 2018 and July 2020, 118 of the intended 280 patients were recruited, and 117 were treated (sarilumab = 59, placebo = 58). Median age was 69 years in the treatment group and 70 among those taking placebo.
Of the 117 treated, only 78 patients (67%) completed treatment (sarilumab = 42, placebo = 36). The main reasons for stopping treatment were adverse events – including seven with sarilumab and four with placebo – and lack of efficacy (sarilumab = four, placebo = nine).
The primary outcome was the proportion of patients who reached sustained remission at 52 weeks, defined as disease remission by week 12 and no disease flare, normal C-reactive protein (CRP), and adherence to the glucocorticoid taper during weeks 12-52.
The researchers found that sustained remission was significantly higher in the sarilumab arm versus the control group (28.3% versus 10.3%; P = .0193).
IL-6 inhibitors lower CRP, but if you take CRP out of the definition, Dr. Spiera said, “we still saw this difference: 31.7% of patients treated with sarilumab and 13.8% treated with placebo and a longer taper achieved that endpoint.”
Forty-four percent lower risk of flare with sarilumab
Patients in the sarilumab group also had 44% lower risk of having a flare after achieving clinical remission versus the comparator group (16.7% versus 29.3%; hazard ratio, 0.56; 95% confidence interval, 0.35-0.90; P = .0153).
Patient-reported outcomes, which included physical and mental health scores and disability index results, favored sarilumab.
The incidence of treatment-emergent adverse events (TEAEs) was numerically higher in the sarilumab group, compared with the control group (94.9% versus 84.5%). TEAEs included neutropenia (15.3%) and arthralgia (15.3%) in the sarilumab group and insomnia (15.5%) in the comparator arm.
However, the frequency of serious AEs was higher in the control group, compared with the sarilumab arm (20.7% versus 13.6%). No deaths were reported, and, importantly in this age group treated with concurrent glucocorticoids and an IL-6 inhibitor, Dr. Spiera said, “there were no cases of diverticulitis requiring intervention.”
Dr. Spiera was asked about a seemingly low remission rate. He answered that the bar was very high for remission in this study.
Patients had to achieve remission by week 12 and with the rapid 14-week taper. “That means by week 12 the sarilumab arm patients were only on 2 mg of daily prednisone or its equivalent,” he said.
Patients had to maintain that for another 40 weeks, he noted, adding, “I think especially in the context of quality of life and function indices, these were important results.”
Sebastian E. Sattui, MD, director of the University of Pittsburgh Medical Center vasculitis clinic, told this news organization that prolonged use of glucocorticoids in patients with PMR remains an important concern and the need for other options is critical.
“Around 30% of patients with PMR remain on prednisone 5 years after diagnosis,” he said. “Low-dose glucocorticoids are still associated with significant morbidity. Until recently, there has been a paucity of high-quality data regarding the use of steroid-sparing agents in PMR. “
He noted that the SAPHYR trial data are promising “with sarilumab being successful in achieving remission while minimizing glucocorticoids in patients with relapsing PMR.” The clinically meaningful improvement in patient-reported outcomes was just as important, he added.
The main unanswered question is whether the disease-modifying ability of sarilumab will continue after it is stopped, Dr. Sattui said.
Dr. Spiera is a consultant for Sanofi, which funded the trial. He also disclosed financial relationships with GlaxoSmithKline, Boehringer Ingelheim, Corbus, InflaRx, AbbVie/Abbott, Novartis, Chemocentryx, Roche, and Vera. Dr. Sattui has received research support from AstraZeneca and has done unpaid consulting work for Sanofi.
