In a bid to stop abuse and diversion of the anticonvulsant gabapentin, a watchdog group is petitioning federal regulators to make the drug a controlled substance.

The nonprofit group Public Citizen has filed a petition with the U.S. Food and Drug Administration and the Drug Enforcement Administration (DEA), arguing that the medication’s risks warrant additional safeguards.

Gabapentin is a generic drug, best known under the brand name Neurontin. The petition also covers the related drug gabapentin enacarbil (Horizant).

Public Citizen requested that gabapentin come under the DEA’s Schedule V category, which already includes the similar drug pregabalin (Lyrica). Schedule V is the lowest rung on the DEA’s drug schedule, meaning it has lower potential for abuse then Schedule I through IV drugs. This tier also includes cough preparations with less than 200 milligrams of codeine.

Classifying gabapentin as a Schedule V drug would facilitate better tracking of the drug’s use and misuse and put in place educational and limitation requirements to mitigate the risk of addiction, overdose, and death, Michael Abrams, MPH, PhD, senior health researcher with Public Citizen’s Health Research Group, and colleagues write in the petition.
 

‘Widespread misuse’

There is “substantial evidence of widespread misuse” of gabapentin, plausibly helped by “extraordinary levels of off-label prescribing,” Public Citizen said in the petition.

Some estimates have pegged off-label use at more than 90%, with gabapentin prescribed for indications such as chronic cough, hiccups, postoperative pain, and postmenopausal hot flashes, the group said.

“Moreover, there are numerous reports indicating that gabapentin is widely used and diverted on the street to induce ‘highs’ or otherwise self-medicate,” Public Citizen said. “Both gabapentin and pregabalin have been empirically linked to the opioid overdose epidemic as drugs that potentiate the activity of these oftentimes deadly analgesics.”

This news organization tried several times to reach Azurity for comment but did not receive a response. Pfizer included gabapentin in the portfolio of drugs used to create the Viatris spin-off, which took place in 2020. Pfizer referred this news organization to Viatris for comment, but it also did not respond.

It is unclear how the FDA and DEA will respond to the petition. Public Citizen has received a reply from the FDA, in which the agency acknowledged receipt of the petition. However, the “acceptance of the petition for filing is a procedural matter and in no way reflects the agency’s decision on the substantive merits of the petition,” the FDA said in a letter.

As is common practice, the agency assigned a docket number for the petition, FDA-2022-P-0149. The docket’s website allows interested parties to track the issue.
 

‘Unnoticed’ abuse

There have been rising concerns about risks and abuse of gabapentin in recent years. In its petition, Public Citizen noted that the United Kingdom and several U.S. states have already sought tighter control of gabapentin prescriptions.

In 2019, the United Kingdom announced it would reclassify both pregabalin and gabapentin as class C controlled substances because of the rising numbers of deaths linked to the drugs.

As of November 2020, seven states – Alabama, Kentucky, Michigan, North Dakota, Tennessee, Virginia, and West Virginia – had classified gabapentin as a schedule V drug, while another 12 states required prescription monitoring of the drug, Public Citizen noted.

In 2018, researchers at the University of Louisville, Kentucky, a state that has been hit particularly hard by the opioid crisis, tried to draw more attention to the risks of gabapentin.

“Amid the opioid epidemic, abuse of a different prescription painkiller has widely gone unnoticed,” the University said in a press release at the time.

The release highlighted a study led by Rachel Vickers Smith, PhD, assistant professor in the University of Louisville School of Nursing that was published in Psychology of Addictive Behaviors.

It included 33 individuals who reported recent recreational use of gabapentin. Use of the drug was combined with buprenorphine, other opioids, cocaine, and caffeine to produce effects such as muscle relaxation, pain reduction, sleep induction, feeling drunk, and feeling “high.”

In the press release, Dr. Vickers Smith said individuals who abuse gabapentin often mix it with opioids, marijuana, cocaine, and opioid treatment medication, compounding side effects to the central nervous system that include euphoria and sedation.

In addition, some individuals who primarily abused opioid pain medication have turned to gabapentin after law-enforcement actions made it more difficult to obtain prescription opioids, she noted.

“People are looking for other drugs to substitute for opioids, and gabapentin has filled that place for some,” Dr. Vickers Smith said. “Some have said it gives them a high similar to opioids.”
 

FDA 2019 warning

In 2019, the FDA issued a warning about serious breathing difficulties associated with gabapentin and pregabalin in patients with respiratory risk factors.

These factors include opioid use and other drugs that depress the central nervous system, as well as conditions such as chronic obstructive pulmonary disease that reduce lung function. Older patients are also at higher risk, the FDA said.

The agency noted that gabapentinoids are often co-prescribed with opioids for for medical conditions and abused in combination with opioids. Data collected in 2016 from an office-based physician survey showed 14% of patient encounters involving gabapentin also involved opioids, the FDA said.

“Our evaluation shows that the use of these medicines, often referred to as gabapentinoids, has been growing for prescribed medical use, as well as misuse and abuse,” the agency said in its 2019 alert.

A high-fiber diet, especially one rich in soluble fiber, is linked to a lower risk of incident disabling dementia, new research shows.

Investigators administered a dietary survey to 3,700 healthy adults at midlife and then followed them for up to 20 years. They found that participants who consumed the most fiber had approximately a 25% lower risk of developing dementia in later life.

“This study showed that people with a high intake of dietary fiber, especially soluble fiber, have a lower risk of dementia,” study investigator Kazumasa Yamagishi, MD, PhD, professor, department of public health medicine, faculty of medicine and health, Services Research and Development Center, University of Tsukuba, Japan, said in an interview.

“There are still many unknowns about the causes of dementia, and it is not appropriate to determine causality based on the results of a single cohort study. However, the results of this study can be said to be one of the findings that will lead to the prevention of dementia,” Dr. Yamagishi said.

The study was published online Feb. 6 in Nutritional Neuroscience.
 

Brain-gut interaction

Brain-gut interaction has recently received attention for its potential involvement in the development of dementia. “The concept of brain-gut interaction emerged from the idea that the central nervous system communicates bidirectionally with the gastrointestinal tract, suggesting that the gut microbiome may influence brain plasticity and cognitive function,” the authors wrote.

A diet high in soluble fiber attenuates neuroinflammation in mouse models. Other animal studies have suggested that insoluble fiber might also have a beneficial effect on the microbiome.

The researchers wanted to see whether dietary fiber intake – especially soluble fiber – is associated with a reduced risk of dementia. They also investigated whether there was any difference between dementia in patients with vs. without a history of stroke.

In a previous study, these same researchers reported an inverse association between eating beans, which are high in fiber, and risk of disabling dementia. In the current study, the researchers extended the analyses to dietary fiber intake of total, soluble, and insoluble fibers, as well as other fiber-containing foods, such potatoes, vegetables, and fruits. However, they distinguished potatoes from other vegetables because the composition of starch in potatoes differs.

“Dietary fiber is a nutrient found in grains, potatoes, vegetables, and fruits and is known to affect intestinal bacteria,” Dr. Yamagishi said. “Recently, some experimental studies have shown that intestinal bacteria may be involved in cognitive functions as well as diseases of the digestive tract. However, there have been no studies that have actually examined the relationship between dietary fiber intake and the subsequent risk of dementia in large numbers of general people.”

The researchers turned to participants in the Circulatory Risk in Communities Study (CIRCS), an ongoing dynamic community cohort study involving five communities in Japan. The current study focused on communities where disabling dementia surveillance is conducted.

Participants (n = 3,739) ranged in age from 40 to 64 years (mean age, 51 years) at the time they completed the 24-hour dietary recall survey, and they participated in annual health checkups from 1985 to 1999. Potential risk factors for disabling dementia were measured at the time the dietary surveys were conducted. Participants were then followed for a median of 19.7 years (1999-2020) to confirm incident, disabling dementia.

“Disabling dementia” was defined as dementia that required care under the National Long-Term Care Insurance System and was further categorized on the basis of having a history or not having a history of stroke.

The researchers divided participants into quartiles, based on the amount of total, soluble, and insoluble intake reported in their surveys. They found that men tended to consume less total fiber compared to women.
 

Unclear mechanism

During follow-up, 670 participants developed disabling dementia.

Total fiber intake was “inversely and linearly” associated with risk of incident dementia, the authors reported, with each successive quartile associated with a lower risk compared to the lowest quartile (P for trend = .03).

The association remained after adjustment for potential factors that might affect dementia onset, such as body mass index, systolic blood pressure, antihypertensive medication use, serum total cholesterol, cholesterol-lowering medication, and diabetes (P for trend = .05).

“The inverse association was more evident for soluble fiber intake and was confined to dementia without a history of stroke,” the authors reported. Moreover, potatoes, not vegetables or fruits, showed a similar association.

“The mechanisms are currently unknown but might involve the interactions that take place between the gut and the brain,” Dr. Yamagishi said in a release.

“One possibility is that soluble fiber regulates the composition of gut bacteria. This composition may affect neuroinflammation, which plays a role in the onset of dementia,” he suggested. “It’s also possible that dietary fiber may reduce other risk factors for dementia, such as body weight, blood pressure, lipids, and glucose levels.”

The authors noted several limitations. For example, they did not distinguish between Alzheimer’s and non-Alzheimer’s dementia. Moreover, they classified dietary habits on the basis of a single survey, and participants’ dietary patterns might have changed over the study period.

In addition, Dr. Yamagishi noted, it is “important to confirm the association in other populations.”
 

Balance is key

In an interview, Uma Naidoo, MD, director of nutritional and lifestyle psychiatry, Massachusetts General Hospital, and nutrition educator at Harvard Medical School, both in Boston, said the study “adds to the growing pool of evidence suggesting that a diet rich in colorful, plant-based foods can benefit our neurological and psychiatric health, especially as we age.”

Dr. Naidoo, a chef and the author of “This Is Your Brain on Food,” who was not involved in the study, continued, “In nutritional psychiatry, balance is key and therefore consuming a well-rounded diet including ample amounts of fiber – particularly from sources like steel-cut oats, beans, lentils, and numerous other fruits and vegetables – can be part of a healthy lifestyle and prevention against cognitive decline in later years.

“While the study authors admit to limitations within the study, in my opinion, eating healthier has so many mental and physical health benefits that it’s a nutritional psychiatry no-brainer,” she added.

The study was partly supported by Health and Labour Science Research Grants for Dementia from the Ministry of Health, Labour and Welfare of Japan; JSPS Kakenhi; FULLHAP; and the Osaka University International Joint Research Promotion Programme with University College London. The authors and Dr. Naidoo report no relevant financial relationships.

“While the study authors admit to limitations within the study, in my opinion, eating healthier has so many mental and physical health benefits that it’s a nutritional psychiatry no-brainer,” she added.

The study was partly supported by Health and Labour Science Research Grants for Dementia from the Ministry of Health, Labour and Welfare of Japan; JSPS Kakenhi; FULLHAP; and the Osaka University International Joint Research Promotion Programme with University College London. The authors and Dr. Naidoo report no relevant financial relationships.

Researchers have identified markers in saliva that are differentially expressed in children with autism spectrum disorder (ASD) who have gastrointestinal (GI) disturbances.

These findings mark the beginning of an understanding of the biological differences separating kids with ASD with and without GI disturbances, study investigator David Q. Beversdorf, MD, professor of radiology, neurology and psychology, department of psychological sciences, University of Missouri, Columbia, told this news organization.

“The hope is this will lead us in future to markers that help guide targeted precision treatments of gastrointestinal disorders” in children with autism, with the ultimate goal of improving their quality of life, said Dr. Beversdorf.

The study was published online Jan. 20 in Frontiers in Psychiatry.
 

Anxiety a key driver?

GI disorders, particularly constipation, are common in children with ASD. Previous research by Dr. Beversdorf and colleagues suggests that anxiety may be driving the relationship between gut disturbances and autism.

Research shows some children with ASD respond well to traditional treatments such as laxatives, while others do not. However, the reasons for this are unclear.

“It would be great to know who those great responders are,” said Dr. Beversdorf. “Subtyping and using biomarkers might be biologically meaningful” because this could identify distinct groups.

The case-control study included 898 children aged 18-73 months recruited from outpatient pediatric clinics affiliated with seven academic medical centers across the United States. The average age of the sample was 44 months and participants were mainly White (76%), non-Hispanic (89%), and male (73%).

The children fell into three neurodevelopmental categories: ASD (n = 503), non-ASD developmental delay (DD, n = 205), and typical development (TD, n = 190).

ASD was diagnosed using standardized assessment tools including the Autism Diagnostic Observation Scale, second edition (ADOS-2). DD participants had delays in gross motor skills, fine motor skills, language, or cognitive development but did not meet criteria for ASD.

Including children with DD could address whether biological markers are specific to autism or to developmental disorders in general, noted Dr. Beversdorf.

TD participants, recruited at the time of their annual well-child visit, did not exhibit developmental delays.
 

Links to GI disturbance, behavior

Researchers subdivided participants into those with GI disturbances (n = 184) and those without these disturbances (n = 714). This was based on medical record review and parental report of disorders such as constipation, reflux, chronic diarrhea or abdominal pain, and food intolerance.

As expected, investigators found more children with ASD reported GI disturbance (22%) than with TD (10%). In children with ASD, rates of constipation (11%) and reflux (6%) were higher than rates among those with TD (3% and 0.5%, respectively).

However, rates of GI disturbances in children with ASD were similar to those with DD.

Investigators used a swab to obtain a saliva sample from participants in a nonfasting state. Saliva is a feasible and often favored source for sampling GI-related biology. Unlike stool microbiome, the saliva microbiome can be repeatedly sampled on demand and has shown resilience to antibiotics.

Researchers examined numerous RNAs, which are “incredibly biologically relevant,” said Dr. Beversdorf.

Investigators compared levels of 1,821 micro-transcriptome features across neurodevelopmental status and the presence or absence of GI disorders.

They also examined micro-transcriptome levels among GI subgroups (constipation, reflux, food intolerance, other GI condition, no GI condition). In addition, they identified RNAs that differed among children taking three common GI medications. These included probiotics, reflux medication, or laxatives.

The investigators found five piwi-interacting RNAs, which are small noncoding RNA molecules and three microbial RNAs in saliva that displayed an interaction between developmental status and GI disturbance. Fifty-seven salivary RNAs differed between GI subgroups, with microRNA differences found between food intolerance and reflux groups being the most common.

The analysis identified 12 microRNAs that displayed relationships with GI disturbance, behavior, and GI medication use.
 

First exploration

However, Dr. Beversdorf cautioned about the medication finding. “I can’t speak confidently about what we see there because with each group you get much, much smaller sample sizes with each individual treatment approach.”

The researchers looked at downstream targets of the 12 microRNAs and found involvement with 13 physiologic pathways. These included long-term depression, metabolism, and digestion pathways.

The metabolism and digestion pathways make sense, but it’s unclear why an addiction-related pathway would be involved, said Dr. Beversdorf. However, he noted children with autism do display obsessive features.

Experts don’t know if RNA changes are a cause of, or a response to, GI problems. “It could be the pain of constipation is triggering, say, these addiction pathway changes,” said Dr. Beversdorf.

The study is the “first exploration” into possible specific targets for treating GI disturbances in autism, said Dr. Beversdorf. “We hope these biomarkers will eventually give us an indication of which patients are going to respond to the individual approach to treating their constipation, their diarrhea, or whatever it is.”

The investigators plan to study whether RNA biomarkers determine which patients respond to different treatments targeting constipation, said Dr. Beversdorf.

A study limitation was that GI disturbances were not assessed by physicians. In addition, the term “GI disturbance” groups together loosely related pathology occurring in the GI tract, although there are important physiologic differences between conditions such as constipation and reflux.

The study received funding from the National Institutes of Health.

A prescription, digital therapeutic shows measurable brain changes that correlate with improved attention control in children with attention-deficit/hyperactivity disorder (ADHD).

Investigators found children who used the video game-based therapy (EndeavorRx) experienced increased brain activity related to attention function, as measured by EEG, which correlated with improvements in objective behavioral measures of attention.

“While the previous multicenter trials show attention improvement for children using EndeavorRx, this is the first study to look at the brain activity in children with a primary concern of ADHD,” principal investigator Elysa Marco, MD, clinical executive for neurodevelopmental medicine at Cortica Healthcare, San Rafael, Calif., said in news release.

“It is exciting to see measurable improvement on the EEGs that correlates with the behavioral benefits,” said Dr. Marco.

The study was recently published online in PLOS ONE. 
 

Measurable changes

As previously reported by this news organization, the Food and Drug Administration approved EndeavorRx in June 2020 as a prescription video game–based therapeutic device for children aged 8-12 years with primarily inattentive or combined-type ADHD, who have a demonstrated attention issue.

“The device is intended for use as part of a therapeutic program that may include clinician-directed therapy, medication, and/or educational programs, which further address symptoms of the disorder,” the FDA said upon approval.

In the current unblinded, single-arm study, the researchers assessed 25 children (aged 8-12 years) with a confirmed diagnosis of ADHD on neural, behavioral, and clinical metrics of attention before and after a 4-week at-home intervention.

Participants were instructed to use EndeavorRx for about 25 minutes a day at least 5 days a week for 4 weeks, as recommended by the FDA.

“EndeavorRx enhanced midline frontal theta (MFT) activity, suggesting that patients who used EndeavorRx for 4 weeks showed changes in measurable brain function,” Anil S. Jina, MD, chief medical officer of Akili Interactive, told this news organization. Dr. Jina was not involved with the study.

There was also a correlation between MFT activity and attention functioning, “suggesting that children who experienced the largest gains in MFT activity as measured by EEG also showed the greatest improvements in computerized performance tests designed to measure attention,” Dr. Jina said.

In addition, parents reported significantly fewer inattention symptoms in children after EndeavorRx treatment, as measured by the Vanderbilt ADHD Diagnostic Rating Scale.
 

‘Not just another video game’

EndeavorRx has been evaluated in five clinical studies involving more than 600 children with ADHD, including the STARS-ADHD trial, a prospective, randomized, controlled study published in The Lancet Digital Health.

The STARS-ADHD trial randomly allocated 348 children to either EndeavorRx treatment or a controlled intervention, which was a word game.

The researchers reported statistically significant improvements in attentional functioning in the EndeavorRx group as rated by test of variables of attention.

“This is not just another video game,” STARS-ADHD trialist Scott H. Kollins, PhD, MS, a clinical psychologist at Duke Health’s ADHD Clinic in Durham, N.C., who helped developed it, previously told this news organization.   

The tool’s adaptive algorithms adjust and monitor task difficulty based on performance, using a video game format and rewards to engage users, he explained. EndeavorRx is a challenge to play by design.

“The treatment was programmed into the gameplay experience and designed to challenge a child’s attentional control during gameplay, requiring focus and flexibility to manage tasks at the same time,” Dr. Jina said in an interview.

“Unlike a video game that is designed only for entertainment purposes, to drive efficacy, EndeavorRx is designed to be challenging and can therefore sometimes feel repetitive, and frustrating to some children,” Dr. Jina said.

Commenting on the study, Stephen Faraone, PhD, distinguished professor of psychiatry and vice chair of research, department of psychiatry, State University of New York, Syracuse, said this study “supports the idea that EndeavorRx improves a neural measure of attention.

“The limitation is that we don’t know if this translates into clinically relevant outcomes,” cautioned Dr. Faraone, who was not associated with the current study.

“The main caveat about EndeavorRx is that it was cleared by the FDA for improving a computer-based measure of inattention, not inattentive symptoms as reported by the parents of children with ADHD,” he noted.

Several authors have disclosed financial relationships with Akili Interactive Labs, which funded the study. Dr. Faraone was an investigator on the STARS-ADHD trial.

Tremors and memory symptoms were identified among individuals in a primary care setting as early as 10 years before a Parkinson’s disease diagnosis in a new study.

Most research on the causes and early signs of Parkinson’s disease (PD) have involved patients of Northern European ancestry, Cristina Simonet, MD, of Queen Mary University of London, and colleagues wrote in their paper, published in JAMA Neurology.

Additionally, data on how PD might manifest in different ethnic groups are limited, they said.

In their nested case-control, the researchers examined data from electronic health records of an ethnically diverse population of 1,016,277 adults seen in primary care practices between 1990 and Feb. 6, 2018. They compared individuals with PD with those without PD or other neurologic conditions.

The researchers identified 10 age and sex-matched controls for each PD case, and also conducted an unmatched analysis after adjusting for age and sex. The final study population included 1,055 patients with PD and 1,009,523 controls. The population of PD cases was 15.7% Black, 19.7% South Asian, 50.9% White, and 8.3% other; the population of controls was 13.3% Black, 21.5% South Asian, 43.7% White, and 11.3% other.

“We observed a constellation of symptoms noted by general practitioners up to a decade before diagnosis of PD,” the researchers said. Symptoms were identified across three time intervals (less than 2 years, 2-5 years, and 5-10 years before diagnosis) to better evaluate exposure outcome associations.

In the matched analysis of midlife risk factors, epilepsy showed the strongest association with PD diagnosis across all time periods, and type 2 diabetes or hypertension 5-10 years before diagnosis was associated with later PD.

Prediagnostic signs of PD included both motor and nonmotor manifestations.

The matched analysis revealed a significant increased association between tremor and memory symptoms less than 2 years before diagnosis (adjusted odds ratios of 151.24 and 8.73, respectively) as well as up to 10 years before diagnosis for tremors and up to 5 years for memory symptoms (aOR, 11.4 and 3.09, respectively) in PD patients, compared with controls.

Other strong associations between PD and early nonmotor features in cases, compared with controls, included hypotension (aOR, 6.81), constipation (aOR, 3.29), and depression (aOR, 4.61).

In addition, the researchers found associations for epilepsy that had not been identified in previous studies, and these associations persisted in a replication analysis.

The study findings were limited by several factors, mainly the use of routine primary care data with underascertained factors of interest, and potential mislabeling of PD, the researchers noted. Other limitations included the lack of data on prescription medication for PD, and the recording of memory problems in primary care without supportive testing to confirm cognitive impairment.

The results support a range of comorbidities and symptoms that may present in primary care, and clinicians should consider PD as a possible cause, the researchers wrote.
 

Make early referral a priority

The study is important because of the lack of diversity in Parkinson’s disease research, lead author Dr. Simonet said in an interview.

“Over the last decade, the global population suffering from Parkinson’s disease has more than doubled,” she said. Causes may include the increasing numbers of older people with longer life expectancy. “However, it seems there are other factors, including environmental, genetic, and lifestyle, that might play a role in increasing the prevalence of Parkinson’s disease.”

“More representative studies, including minority ethnic groups and those living in areas of high social and economic deprivation, are needed,” Dr. Simonet emphasized.

She said that there is little research on the association with epilepsy and hearing loss in early PD, and “for that reason, our results should encourage further studies to confirm a possible link between these manifestations and Parkinson’s disease.”
 

Early detection may drive better diagnoses

The current study is important for understanding the prediagnostic features and risk factors that may allow for earlier detection of Parkinson’s disease, William Hung, MD, a geriatrics and palliative care specialist of the Icahn School of Medicine at Mount Sinai, New York, said in an interview. “Prior to this study, there was limited understanding of these features.

“One surprise [in the findings] was that ethnicity and socioeconomic deprivation do not appear to be associated with the risk of PD, in contrast to other illnesses such as dementia,” said Dr. Hung. “The array of prediagnostic features associated with PD is not surprising, but nonetheless important for clinicians to know to consider whether PD could be the underlying cause.”

The take-home message for primary care is that “there are features, such as hearing loss, history of epilepsy, autonomic symptoms, motor symptoms, among others, for which clinicians should consider PD as part of the differential diagnosis as underlying cause and consider referral to specialists for diagnostic clarification,” said Dr. Hung.

“Additional research is needed to translate these findings to care, perhaps developing decision aids, interventions that may help with diagnosis and evaluation,” as is work on understanding the link between PD and symptoms such as hearing loss and epilepsy, he said.
 

Primary care offers opportunity to identify risk factors

The current study represents an important step in early recognition of PD, with implications for helping patients access treatments promptly and improve their quality of life, Bhavana Patel, DO, Shannon Chiu, MD, and Melissa J. Armstrong, MD, of the University of Florida, Gainesville, wrote in an accompanying editorial.

“The primary care setting is commonly where symptoms heralding the onset of PD are first discussed. However, little is known regarding the prediagnostic manifestations of PD that are seen in primary care clinics, particularly in underserved populations,” they wrote.

The study included many risk factors and prodromal markers associated with research criteria for prodromal PD, but did not include several risk and prodromal markers in the Movement Disorders Society research criteria, “such as symptoms suggestive of REM sleep behavior disorder, excessive daytime sleepiness (which overlaps with, but is distinct from, fatigue), urinary dysfunction, pesticide and solvent exposure, caffeine use, level of physical activity, and family history,” they said.

Even in individuals with diagnosed PD, certain symptoms, particularly nonmotor symptoms, are commonly underreported,” and primary care clinicians may not recognize these symptoms as PD risk factors, the authors noted.

However, “in addition to contributing to possible models of modifiable risk factors for PD, study results may also further inform algorithms designed to predict PD diagnoses in primary care,” they said. The study also highlights the need for more multivariable models to better identify PD risk factors and strategies for early identification of PD in primary care.

Several study coauthors received funding related to the study from Barts Charity, Health Data Research UK, the Department of Health and Social Care (England) and the devolved administrations, and leading medical research charities, as well as the National Institute for Health Research UCLH Biomedical Research Centre. Lead author Dr. Simonet and Dr. Hung had no financial conflicts to disclose. Dr. Patel disclosed support from the National Institute on Aging, the Mangurian-Fixel-McKnight Collaboration for Pilot Studies in Lewy Body Dementia, and the American Brain Foundation and the Mary E. Groff Charitable Trust. Dr. Chiu reported receiving grants from Mangurian-Fixel-McKnight Collaboration for Pilot Studies in Lewy Body Dementia and the Smallwood Foundation. Dr. Armstrong disclosed funding from the National Institute on Aging, the Florida Department of Health, the Lewy Body Dementia Association, the Alzheimer’s Therapeutic Research Institute/Alzheimer’s Clinical Trial Consortium, the Alzheimer’s Disease Cooperative Study as Data Safety Monitoring Board the Parkinson’s Foundation, and the American Academy of Neurology.

Tremors and memory symptoms were identified among individuals in a primary care setting as early as 10 years before a Parkinson’s disease diagnosis in a new study.

Most research on the causes and early signs of Parkinson’s disease (PD) have involved patients of Northern European ancestry, Cristina Simonet, MD, of Queen Mary University of London, and colleagues wrote in their paper, published in JAMA Neurology.

Additionally, data on how PD might manifest in different ethnic groups are limited, they said.

In their nested case-control, the researchers examined data from electronic health records of an ethnically diverse population of 1,016,277 adults seen in primary care practices between 1990 and Feb. 6, 2018. They compared individuals with PD with those without PD or other neurologic conditions.

The researchers identified 10 age and sex-matched controls for each PD case, and also conducted an unmatched analysis after adjusting for age and sex. The final study population included 1,055 patients with PD and 1,009,523 controls. The population of PD cases was 15.7% Black, 19.7% South Asian, 50.9% White, and 8.3% other; the population of controls was 13.3% Black, 21.5% South Asian, 43.7% White, and 11.3% other.

“We observed a constellation of symptoms noted by general practitioners up to a decade before diagnosis of PD,” the researchers said. Symptoms were identified across three time intervals (less than 2 years, 2-5 years, and 5-10 years before diagnosis) to better evaluate exposure outcome associations.

In the matched analysis of midlife risk factors, epilepsy showed the strongest association with PD diagnosis across all time periods, and type 2 diabetes or hypertension 5-10 years before diagnosis was associated with later PD.

Prediagnostic signs of PD included both motor and nonmotor manifestations.

The matched analysis revealed a significant increased association between tremor and memory symptoms less than 2 years before diagnosis (adjusted odds ratios of 151.24 and 8.73, respectively) as well as up to 10 years before diagnosis for tremors and up to 5 years for memory symptoms (aOR, 11.4 and 3.09, respectively) in PD patients, compared with controls.

Other strong associations between PD and early nonmotor features in cases, compared with controls, included hypotension (aOR, 6.81), constipation (aOR, 3.29), and depression (aOR, 4.61).

In addition, the researchers found associations for epilepsy that had not been identified in previous studies, and these associations persisted in a replication analysis.

The study findings were limited by several factors, mainly the use of routine primary care data with underascertained factors of interest, and potential mislabeling of PD, the researchers noted. Other limitations included the lack of data on prescription medication for PD, and the recording of memory problems in primary care without supportive testing to confirm cognitive impairment.

The results support a range of comorbidities and symptoms that may present in primary care, and clinicians should consider PD as a possible cause, the researchers wrote.
 

Make early referral a priority

The study is important because of the lack of diversity in Parkinson’s disease research, lead author Dr. Simonet said in an interview.

“Over the last decade, the global population suffering from Parkinson’s disease has more than doubled,” she said. Causes may include the increasing numbers of older people with longer life expectancy. “However, it seems there are other factors, including environmental, genetic, and lifestyle, that might play a role in increasing the prevalence of Parkinson’s disease.”

“More representative studies, including minority ethnic groups and those living in areas of high social and economic deprivation, are needed,” Dr. Simonet emphasized.

She said that there is little research on the association with epilepsy and hearing loss in early PD, and “for that reason, our results should encourage further studies to confirm a possible link between these manifestations and Parkinson’s disease.”

Among children and adolescents aged 5-18 years, concussion was associated with a higher risk of mental health problems, compared with age- and sex-matched children and adolescents with an orthopedic injury, according to a cohort study published in JAMA Network Open.

While concussions are one of the most common head injuries in the pediatric population, the extent to which they increase the risk of new onset psychiatric disorders or subsequent psychopathology is unclear, lead author Andrée-Anne Ledoux, PhD, of the Children’s Hospital of Eastern Ontario Research Institute, Ottawa, and colleagues explained.

The researchers conducted a population-based retrospective cohort study to evaluate associations between concussion and risk of subsequent mental health issues, psychiatric hospitalizations, self-harm, or suicides in children and adolescents, with follow-up ranging from 1 month to 10 years.

The data were obtained from province-wide health administrative databases. Participants with concussion were included in an exposed group, while those with an orthopedic injury were included in a 1:2 age- and sex-matched comparison group.
 

Results

The study cohort comprised 448,803 participants, including 152,321 and 296,482 children and adolescents with concussion and orthopedic injury, respectively.

The incidence rates of any mental health problem were 11,141 per 100,000 person-years in the exposed group and 7,960 per 100,000 person-years in the unexposed group (difference, 3,181; 95% confidence interval, 3,073-3,291 per 100,000 person-years).

After concussion, the exposed group had a greater risk of developing a mental health issue (adjusted hazard ratio, 1.39; 95% CI, 1.37-1.40), psychiatric hospitalization (aHR, 1.47; 95% CI, 1.41-1.53), and self-harm (aHR, 1.49; 95% CI, 1.42-1.56). In addition, there was no significant difference in death by suicide between the exposed and unexposed groups (HR, 1.54; 95% CI, 0.90-2.61).

“Our results suggest that clinicians should assess for preexisting and new mental health symptoms throughout concussion recovery and treat mental health conditions or symptoms or refer the patient to a specialist in pediatric mental health,” wrote Dr. Ledoux and colleagues. “[Clinicians should also] assess suicidal ideation and self-harm behaviors during evaluation and follow-up visits for concussion.”

The researchers acknowledged that a key limitation of the study was the retrospective observational design. In addition, the identification of exposures using diagnostic billing codes could have introduced exposure or outcome misclassification.
 

Expert-recommended resources

“For more information, I’d recommend ‘Pedsconcussion,’ which are evidence-based living guidelines for pediatric concussion care,” Dr. Ledoux said in an interview. “Within domain 8, there are specific guidelines related to the management of mental health issues post concussion.”

Neuropsychology expert Talin Babikian, PhD, of the University of California, Los Angeles, commented: “Studies have shown that even a single psychoeducational session early after a concussion can minimize prolonged recoveries. Ensuring all stakeholders (family, clinicians, school, coach, peers) are on the same page and providing the same information is important to build trust and a sense of safety and agency.

“We want to provide psychoeducation early in the process to avoid unnecessary fear and avoidance. We also want to curtail misattribution of everyday symptoms or symptoms related to an unrelated condition to a brain injury, which are easier to do when caught early,” Dr. Babikian added.

This study was supported by the Institute for Clinical Evaluative Sciences, which is funded by an annual grant from the Ontario Ministry of Health and the Ministry of Long-term Care. One author reported financial relationships with the University of Ottawa, the National Football League, Parachute Canada, and 360 Concussion Care, an interdisciplinary concussion clinic; no other conflicts of interest were reported.

Many emergency departments are currently unable to provide care for geriatric patients that meets best practices and guidelines recommended by several major medical organizations, but a panel discussion in 2021 at the American Academy of Emergency Medicine’s Scientific Assembly identified three areas in which realistic improvements might be achieved.

In an article published online in the Journal of Emergency Medicine, Richard D. Shih, MD, of Florida Atlantic University, Boca Raton, and colleagues synthesized the presentation and discussion of an expert panel on the topic of the GED guidelines and the current realities of patient care.

The Geriatric Emergency Department (GED) Guidelines, published in 2014 in Annals of Emergency Medicine, were endorsed by the American College of Emergency Physicians, American Geriatrics Society, Emergency Nurses Association, and Society for Academic Emergency Medicine.

“With the substantial challenges in providing guideline-recommended care in EDs, this article will explore three high-impact GED clinical conditions to highlight guideline recommendations, challenges, and opportunities, and discuss realistically achievable expectations for non–GED-accredited institutions,” the authors wrote. The article addressed the ED patient with delirium, the ED fall patient, and the ED patient with polypharmacy.
 

Geriatric patients and delirium

When delirium in older adults is not identified in the ED, the patient’s 6-month mortality rate significantly increases, but few EDs have delirium screening protocols, the authors said. Challenges included the time and money needed to educate staff, on top of multiple mandatory training requirements on other topics. Delirium screening in the clinical setting also requires personnel to conduct assessments, and time to document symptoms and screening results in medical records.

“Perhaps the highest priority challenge for delirium experts is to evaluate and publish effective delirium intervention strategies because current evidence is completely lacking for ED-based delirium prevention or treatment,” they said. In the meantime, developing outcome measures for quality improvement of delirium care will require institutional support as well as education.
 

Geriatric patients and falls

Approximately one third of community-dwelling adults older than 65 years suffer falls, but data suggest that fewer than half of these individuals report falls to their doctors. “Older adults who present to an ED after a fall have an approximately 30% greater risk of functional decline and depression at 6 months after the event,” the authors noted.

The GED guidelines call for a comprehensive approach to evaluating and managing falls in older adults, but many of these “are untested in the ED,” the authors said. The recommended protocol includes an initial assessment of fall risk, followed by, for those at low risk, tailored recommendations for education and the use of community resources. Additional recommendations for those at high risk of falls include multifactorial assessment of modifiable risk factors, including peripheral neuropathy, balance/gait assessment, and medication review.

However, this best practice workflow is beyond the resource capacity of most EDs, the authors noted. “When ED resources are insufficient to support best practices, the care should focus on educating patients and caregivers about the significance of a fall event, providing educational materials (e.g., [the Centers for Disease Control and Prevention’s] STEADI materials), and assessing safety with respect to mobility for immediate return to the home environment and follow-up with a PCP.”
 

Geriatric patients and polypharmacy

Polypharmacy is common among older adults by virtue of their greater number of illnesses and comorbid conditions, and polypharmacy also has been associated with more adverse drug reactions, the authors said. The AGS Beers Criteria identifies medications associated with adverse drug reactions, but it is not practical for use in a busy ED setting. Instead, the authors suggested a more practical approach of focusing on a smaller list of common medications that tend to cause the adverse events that may result in ED visits.

“Perhaps targeting patients on multiple (three or more) psychoactive medications, drugs that can cause hypotension, or hypoglycemics could not only be done quickly, but identify patients in whom deprescribing should be considered in the ED,” the authors wrote. Deprescribing is a complicated process, however, and may be more effective when done via the patient’s primary care provider or in a geriatric consultation.

The GED Guidelines highlighted the specific needs of the geriatric population in the ED, the authors said. Widespread implementation remains a challenge, but many organizations provide resources to help improve care of geriatric patients in the ED and beyond.

In particular, the Geriatric Emergency Care Applied Research Network and Geriatric Emergency Department Collaborative provide funding opportunities, updated and focused published reviews, and webinars (some including free continuing medical education) for the entire health care team, including hospital administrators, the authors said.
 

Article brings attention to clinical realities

“The reality is that the overwhelming majority of emergency departments in the United States, if not globally, are simply not equipped – operationally or financially – to meet the rigorous standards that are required to fulfill the goals of operating an accredited geriatric ED,” Robert D. Glatter, MD, an emergency medicine physician at Lenox Hill Hospital, New York, said in an interview.

“Drawing attention to this important gap in accreditation is critical to not only inform hospitals, health care providers and stakeholders, but the public, patients, and their families about the important work that needs to be done to better equip all EDs with the proper tools and educational approaches to more effectively care for the geriatric community,” Dr. Glatter emphasized.

“There are currently three tiers of accreditation, with level 1 being the highest,” he explained, but there are only 100 geriatric ED accreditation-certified hospitals across the United States.

“I am not surprised at all by the challenges of implementing current GED guidelines,” said Dr. Glatter. “It comes down to operational and budget considerations, which ultimately compete with many other departments and regulatory constraints in any given hospital.”

However, “the bottom line is that such guidelines are designed with patient safety in mind, making them important issues in the eyes of any hospital administrator looking to improve outcomes and reduce medicolegal risk or exposure impacting geriatric patients in the emergency department,” he noted. 

Ultimately, guideline adherence “comes down to budget decisions, and where hospitals must invest their money to meet the bottom line,” said Dr. Glatter. “Making modifications to hospital infrastructure and architecture to accommodate geriatric patients may not be the top priority of hospital administrators when confronted with multiple competing interests. But, if it impacts patient safety, the decision to invest in structural and operational improvements may certainly have additional and important considerations.

“Until Medicare, or even the Joint Commission on Accreditation of Hospitals, adopts geriatric guidelines in emergency departments as a requirement for accreditation, there may not be adequate incentives in place currently to satisfy the intent of having a rigorous set of guidelines in the first place,” Dr. Glatter added. 

Despite the limitations of applying the current guidelines, there are some steps hospitals can take, said Dr. Glatter. “They can institute new measures in a graded fashion, with the goal of taking the important steps to satisfy at least some components of the guidelines. Attention to details can go a long way, such as rails in bathrooms, better lighting, and treads on floors that may reduce the risk of falls in the ED itself.

“Attention to fall prevention by assessing contributors including polypharmacy, gait instability, and quality of footwear can impact risk of future ED visits. Having incentives in place by Medicare or JACO may force the hand of hospital administrators to comply with geriatric guidelines and place emphasis on compliance,” noted Dr. Glatter.

More research is needed that “looks at costs of implementing geriatric guidelines in typical community and academic EDs and how this impacts key metrics such as length of stay, effect on reimbursement per ICD-10 code, and savings, if any, realized in reduced malpractice claims related to missed diagnoses (such as delirium), injuries, (patient falls), or medical misadventures due to polypharmacy,” he said.

Many emergency departments are currently unable to provide care for geriatric patients that meets best practices and guidelines recommended by several major medical organizations, but a panel discussion in 2021 at the American Academy of Emergency Medicine’s Scientific Assembly identified three areas in which realistic improvements might be achieved.

In an article published online in the Journal of Emergency Medicine, Richard D. Shih, MD, of Florida Atlantic University, Boca Raton, and colleagues synthesized the presentation and discussion of an expert panel on the topic of the GED guidelines and the current realities of patient care.

The Geriatric Emergency Department (GED) Guidelines, published in 2014 in Annals of Emergency Medicine, were endorsed by the American College of Emergency Physicians, American Geriatrics Society, Emergency Nurses Association, and Society for Academic Emergency Medicine.

“With the substantial challenges in providing guideline-recommended care in EDs, this article will explore three high-impact GED clinical conditions to highlight guideline recommendations, challenges, and opportunities, and discuss realistically achievable expectations for non–GED-accredited institutions,” the authors wrote. The article addressed the ED patient with delirium, the ED fall patient, and the ED patient with polypharmacy.
 

Geriatric patients and delirium

When delirium in older adults is not identified in the ED, the patient’s 6-month mortality rate significantly increases, but few EDs have delirium screening protocols, the authors said. Challenges included the time and money needed to educate staff, on top of multiple mandatory training requirements on other topics. Delirium screening in the clinical setting also requires personnel to conduct assessments, and time to document symptoms and screening results in medical records.

“Perhaps the highest priority challenge for delirium experts is to evaluate and publish effective delirium intervention strategies because current evidence is completely lacking for ED-based delirium prevention or treatment,” they said. In the meantime, developing outcome measures for quality improvement of delirium care will require institutional support as well as education.
 

Geriatric patients and falls

Approximately one third of community-dwelling adults older than 65 years suffer falls, but data suggest that fewer than half of these individuals report falls to their doctors. “Older adults who present to an ED after a fall have an approximately 30% greater risk of functional decline and depression at 6 months after the event,” the authors noted.

The GED guidelines call for a comprehensive approach to evaluating and managing falls in older adults, but many of these “are untested in the ED,” the authors said. The recommended protocol includes an initial assessment of fall risk, followed by, for those at low risk, tailored recommendations for education and the use of community resources. Additional recommendations for those at high risk of falls include multifactorial assessment of modifiable risk factors, including peripheral neuropathy, balance/gait assessment, and medication review.

However, this best practice workflow is beyond the resource capacity of most EDs, the authors noted. “When ED resources are insufficient to support best practices, the care should focus on educating patients and caregivers about the significance of a fall event, providing educational materials (e.g., [the Centers for Disease Control and Prevention’s] STEADI materials), and assessing safety with respect to mobility for immediate return to the home environment and follow-up with a PCP.”
 

Geriatric patients and polypharmacy

Polypharmacy is common among older adults by virtue of their greater number of illnesses and comorbid conditions, and polypharmacy also has been associated with more adverse drug reactions, the authors said. The AGS Beers Criteria identifies medications associated with adverse drug reactions, but it is not practical for use in a busy ED setting. Instead, the authors suggested a more practical approach of focusing on a smaller list of common medications that tend to cause the adverse events that may result in ED visits.

“Perhaps targeting patients on multiple (three or more) psychoactive medications, drugs that can cause hypotension, or hypoglycemics could not only be done quickly, but identify patients in whom deprescribing should be considered in the ED,” the authors wrote. Deprescribing is a complicated process, however, and may be more effective when done via the patient’s primary care provider or in a geriatric consultation.

The GED Guidelines highlighted the specific needs of the geriatric population in the ED, the authors said. Widespread implementation remains a challenge, but many organizations provide resources to help improve care of geriatric patients in the ED and beyond.

In particular, the Geriatric Emergency Care Applied Research Network and Geriatric Emergency Department Collaborative provide funding opportunities, updated and focused published reviews, and webinars (some including free continuing medical education) for the entire health care team, including hospital administrators, the authors said.

Early results from a new study show a significant correlation between tic severity and social media use during the COVID pandemic in adolescents with a preexisting tic disorder.

The findings should help answer questions surrounding a recent increase in tic disorders, lead author Jessica Frey, MD, a movement disorders fellow at the University of Florida, Gainesville, told this news organization.

University of Florida

“We’re trying to learn why there are new-onset explosive tic disorders [or] functional tic disorders, and to find ways to educate patients, parents, and the general public about what Tourette syndrome looks like – and how we can help patients have a better quality of life,” Dr. Frey said.

The findings will be presented at the American Academy of Neurology 2022 annual meeting in April.
 

‘Robust’ increase

A neurologic disorder that causes sudden repetitive involuntary muscle movements and sounds, Tourette syndrome typically develops in childhood, worsens in adolescence, and improves or completely disappears in adulthood, Dr. Frey noted.

The condition is often negatively portrayed in films, showing people using obscene gestures or vulgar language, she said. Although social media can be an “empowering tool” for tic sufferers, it is unregulated and can be a vehicle for “false information,” she added.

Dr. Frey noted that during the pandemic there has been a “robust” increase in use by teens of social media, particularly TikTok. At the same time, there have been reports of teen girls experiencing “explosive tic onset” that mimics videos from TikTok influencers.

The new analysis included 20 teens with a tic disorder, ranging in age from 11 to 21 years (average age, 16 years). About 45% of participants identified as male, 45% as female, and 10% as nonbinary.

The nature of the tic disorder varied widely among participants. Some had experienced tics for many years, while others only developed tics during the pandemic.

Participants completed a detailed survey, part of which inquired about where they received information about tics, such as from a doctor, media, parents, or teachers.

They were also asked to rank various social media platforms, including Tik Tok, Facebook, and YouTube on a five-point Likert scale as an information source about tics.

In addition, the survey inquired about tic severity and frequency, quality of life, and whether the pandemic or social media affected respondents’ tics.
 

Worsens quality of life

Results showed 65% of respondents used social media at least four to five times per day for an average of 5.6 hours per day. Approximately 90% reported increased use of social media during COVID.

Only 5% of participants reported using social media to provide information about tics.

About half of respondents indicated social media adversely affected their tics, and 85% said their tic frequency worsened during COVID.

Dr. Frey noted that because teens had to attend school virtually, that may have led to increased hours spent online.

There was no significant correlation between social media use and self-reported frequency of tics since the onset of COVID (Pearson correlation coefficient [R], –0.0055, P = .982).

However, there was a statistically significant correlation between social media use and tic severity (R, –0.496, P = .026) and quality of life (R, –0.447, P = .048).

These results suggest teenagers did not develop more tics, but rather the tics they already had worsened and affected their quality of life, Dr. Frey noted. She added that teens sometimes injure themselves while experiencing tics.

The full study has now enrolled 50 participants, and investigators anticipate that number to go up to 80. “We’re hoping to see more patterns emerge when we have a larger cohort of data available,” said Dr. Frey.

Asking parents to weigh in on the impact of social media on their child’s tic condition would be “a great idea for a follow-up study,” she added.
 

Symptoms exacerbated

Commenting on the findings, Tamara Pringsheim, MD, professor in the department of clinical neurosciences, psychiatry, pediatrics, and community health sciences at the University of Calgary (Alta.), said she also has noticed the impact of increased social media use on young patients with tics during the pandemic.

“Many young people report that seeing other people with tics, or ticlike behaviors, can exacerbate their own symptoms,” said Dr. Pringsheim, who is the university’s program lead on Tourette and pediatric movement disorders.

She noted a principle of the Comprehensive Behavioral Intervention for Tics, which is a nonpharmacologic technique demonstrated to reduce tic severity, is to identify antecedents or triggers for tics, and to learn to manage them. It might be a good idea to remind young patients of this principle, said Dr. Pringsheim, who was not associated with the current research.

“I suggest to young people who report specific social media content as a trigger for symptoms to recognize the effect of the exposure on their symptoms and make an informed choice about what they view and how much time they spend on social media,” she added.

The study did not receive any outside funding support. Dr. Frey has disclosed no relevant financial relationships.

Among individuals with multiple sclerosis (MS), disease modifying therapies (DMTs) are associated with a reduced humoral response to SARS-CoV-2 vaccines, according to a new retrospective analysis. The link is particularly strong among B-cell depleting drugs.

“A lot of patients ask us if having MS by itself affects the vaccine response. We did not find that, but it’s about the disease-modifying therapy that a patient is being treated with,” Tirisham Gyang, MD, said in an interview. Dr. Gyang presented the study at a poster session during the annual meeting held by the Americas Committee for Treatment and Research in Multiple Sclerosis (ACTRIMS).

“These patients (on DMTs) had decreased neutralizing antibody levels to the vaccine after they received it. We also saw a similar marker in drugs that modulate the sphingosine S-1 receptor. These patients also had a lower titer. It wasn’t statistically significant, but we think it’s positive. It was underpowered because there was a small number of patients in that subgroup,” said Dr. Gyang, assistant professor of neurology at The Ohio State University.

The results can inform vaccine strategies among people with MS, but the issue remains complex. “I don’t know that we could do a blanket statement and say, if you wait this amount of time, everybody will be okay. It’s a very individualized approach, and patients need to discuss timing of vaccines with their providers, because we know that waiting is better. It’s preferable to wait until towards the end of the dosing cycle. The other factor is making sure that the MS is well treated,” said Dr. Gyang.

The researchers prospectively followed 83 MS patients at the The Ohio State University Wexner Medical Center. Among the cohort, 71% were female. Fifty-one subjects had serum samples analyzed following mRNA COVID-19 vaccination, and they were compared with 38 health care worker controls.

After vaccination, people with MS had about 2.4-fold lower levels of half-maximal neutralization titer (NT50) values compared with health care worker controls. This appeared to be driven primarily by DMTs. There was a more than ninefold reduction in the neutralizing antibody (nAb) response among 13 patients on B-cell depleting agents, compared with no therapy or other therapies (P < .001). Among of individuals on these agents, 61.5% had no detectable nAb.

The researchers also found an association between postvaccine NT50 values and when the vaccine was received compared with the last infusion of B-cell depleting agents. Every additional day since the previous infusion was associated with a 3.7% increase in NT50 value (P = .0032).

The average length of exposure to B-cell depleting agents was 24 months and the median was 25 months. There was no association between length of time on a B-cell depleting agent and NT50 values after vaccination (Spearman correlation 0.35, P = .24).

Subanalyses by sex and vaccine type revealed no differences in nAb levels.

The study did not look at T-cell responses after vaccination or the effect of T-cell depleting agents, and T cells likely still provide some protection, according to Dr. Gyang. “Even though the vaccine response may not be as robust as it would have been if they were not on the drug, there is still some degree of protection,” she said.
 

Some answers, more questions

The study is important, even though it was presented at the time that the COVID-19 Omicron variant surge was waning. “COVID still remains a major concern. Even though it seems to be on the wane at the moment, that doesn’t mean it will be on the wane next week,” said Mark Gudesblatt, MD, medical director at South Shore Neurologic Associates (Patchogue, N.Y.), who was asked to comment on the study.

He noted that about 21% of patients in the study who received a vaccination had no detectable antibodies. “That’s a problem. You need to pick a medication that works, but not if the medication puts you at risk for other problems, especially in the world of now, where we know there are viral pandemics that occur. And that calls into question: What if you’re immunocompromised and you get a flu vaccine or a tetanus vaccine? How much do we know about the vaccination response to most of these? No one really considers [vaccine response] when choosing a medication,” said Dr. Gudesblatt.

The results broadly confirm what has been seen in other studies, though its focus on the humoral response is a limitation, according to Patricia Coyle, MD, professor of neurology and director of Stony Brook (N.Y.) MS Comprehensive Care Center. “For example, there have been independent studies with the (anti-CD-20 therapies) that indicate that they have a normal cell-mediated vaccine response to the COVID vaccine, even though the antibody response may be impaired in a significant number of individuals, though as you continue to vaccinate the antibody response seems to get better,” Dr. Coyle said in an interview.

Dr. Coyle has consulted or received speaker fees from Accordant, Alexion, Biogen, Bristol Myers Squibb, Celgene, GlaxoSmithKline, Horizon Therapeutics, Janssen, Mylan, Novartis, Sanofi Genzyme, TG Therapeutics, and Viela Bio.

Among individuals with multiple sclerosis (MS), disease modifying therapies (DMTs) are associated with a reduced humoral response to SARS-CoV-2 vaccines, according to a new retrospective analysis. The link is particularly strong among B-cell depleting drugs.

“A lot of patients ask us if having MS by itself affects the vaccine response. We did not find that, but it’s about the disease-modifying therapy that a patient is being treated with,” Tirisham Gyang, MD, said in an interview. Dr. Gyang presented the study at a poster session during the annual meeting held by the Americas Committee for Treatment and Research in Multiple Sclerosis (ACTRIMS).

“These patients (on DMTs) had decreased neutralizing antibody levels to the vaccine after they received it. We also saw a similar marker in drugs that modulate the sphingosine S-1 receptor. These patients also had a lower titer. It wasn’t statistically significant, but we think it’s positive. It was underpowered because there was a small number of patients in that subgroup,” said Dr. Gyang, assistant professor of neurology at The Ohio State University.

The results can inform vaccine strategies among people with MS, but the issue remains complex. “I don’t know that we could do a blanket statement and say, if you wait this amount of time, everybody will be okay. It’s a very individualized approach, and patients need to discuss timing of vaccines with their providers, because we know that waiting is better. It’s preferable to wait until towards the end of the dosing cycle. The other factor is making sure that the MS is well treated,” said Dr. Gyang.

Mental disorders in early life are associated with a significantly increased risk of dementia in later years.

Results of a large, longitudinal, population-based study show that individuals hospitalized for a mental health disorder had a fourfold increased relative risk (RR) for developing dementia, compared with those who were not hospitalized with a mental illness.

In addition, those with dementia plus a mental disorder developed dementia almost 6 years earlier than those without a mental illness.

The findings were consistent among men and women, in patients with early- and late-onset dementia, in those with Alzheimer’s and non-Alzheimer’s dementia, and across all mental health disorders – and remained so after accounting for pre-existing physical illness and socioeconomic factors.

“Dementia is not typically treated until later in life, but our study suggests that we need to be thinking about dementia prevention much earlier in the life course,” study investigator Leah Richmond-Rakerd, PhD, assistant professor, department of psychology, University of Michigan, said in an interview.

“Supporting young people’s mental health could be a window of opportunity to help reduce the burden of dementia in older adults,” she said.

The findings were published online Feb. 16.
 

Underappreciated risk factor

“Recognition of the outsized influence of dementia on later-life functioning has fueled research into modifiable risk factors and prevention targets,” the investigators write.

Previous research suggests mental disorders may “comprise an underappreciated category of modifiable risk factors.” However, those studies focused primarily on midlife and older individuals, not on capturing mental disorders during young adulthood, which is the time of “peak prevalence,” they add. In addition, most studies have not explored the full range of mental disorders.

Dr. Richmond-Rakerd noted that it is well known that mental health disorders peak in adolescence and young adulthood – and are treatable.

“If the same people who have mental disorders when they are young tend to develop dementia when they are older, that would mean that preventing mental health problems in younger people might reduce or delay the burden of dementia in older people,” she said.

The investigators assessed records from the New Zealand Integrated Data Infrastructure, which is a de-identified register that includes the entire New Zealand population. They also examined information about hospitalizations and diagnoses from records kept by the New Zealand Ministry of Health.

The researchers followed 1,711,386 individuals born between 1928 and 1967 (50.6% men, aged 21 to 60 years at baseline) for 30 years. The population was subdivided into age groups based on birth years: 1928-1937 (14.8%), 1938-1947 (20.85%), 1948-1957 (29.35%), and 1958-1967 (35.1%).
 

Earlier onset

During the study period, 3.8% of individuals were identified as having a mental disorder, and 2% were identified as having dementia. Similar percentages of men and women had a mental disorder, and similar percentages had dementia.

Dementia was “over-represented” among participants with versus without a mental disorder (6.1% vs. 1.8%). This finding held across all age groups.

Those diagnosed with a mental disorder were also more likely to develop dementia, compared with their peers without a mental disorder (RR, 3.51; 95% confidence interval, 3.39-3.64), which is a larger association than that between physical diseases and dementia (RR, 1.19; 95% CI, 1.16-1.21).

These associations were present in both sexes and in all age groups, although the associations were stronger in more recently born cohorts.

A sixfold higher risk for dementia remained even after adjusting for pre-existing physical illnesses (HR, 6.49; 95% CI, 6.25-6.73); and the elevated risk was evident across different lengths of follow-up from the index mental disorder.

When the researchers focused specifically on individuals diagnosed with dementia, they found that those diagnosed with a mental disorder developed dementia a mean of 5.60 years earlier than those without a mental disorder diagnosis – an association observed across both sexes and all age groups.

“Individuals diagnosed with psychotic, substance use, mood, neurotic, and all other mental disorders and who engaged in self-harm were all more likely than those without a mental disorder to be diagnosed with subsequent dementia, even after accounting for their physical disease histories,” the investigators write.

Although there was a link between mental disorders in both Alzheimer’s and non-Alzheimer’s dementias, the association was larger in non-Alzheimer’s.

The researchers note that the study has several limitations, including the fact that it was conducted in New Zealand and therefore the results may not be generalizable to other regions. In addition, inpatient hospital records do not capture less severe mental disorder cases treated in the outpatient setting.

Dr. Richmond-Rakerd suggested several potential mechanisms that could account for the link between mental illness and dementia, including poor lifestyle choices and metabolic side effects associated with some psychiatric medications.

“There could also be shared risk factors for both mental disorders and dementia, such as shared genetics, or individuals may experience a lifelong brain vulnerability that shows up as mental health problems earlier in life and shows up as dementia later in life,” she said.
 

An important risk factor

Commenting for this article, Ken Duckworth, MD, chief medical officer of the National Alliance on Mental Illness, said a major strength of the study was its longitudinal scope and large population size.

He described the study as allowing clinicians to “watch the movie,” as opposed to looking at a “snapshot” of data.

“Although you can learn things from snapshots, a large, comprehensive public health system looking at 30 years of claims – something not possible in the U.S. because of our more fragmented health care system – offers more insight,” said Dr. Duckworth, who was not involved with the research.

The investigators are “painting a picture of a correlation of risk, and to me, that’s the beginning of further inquiry,” he added. “Would preventive efforts targeting dementia, such as exercise and socialization, be helpful? It’s a great study that raises these interesting questions.”

Also commenting in an interview, Claire Sexton, DPhil, director of scientific programs and outreach at the Alzheimer’s Association, said the study “adds a wealth of data to our understanding” of mental disorders as a dementia risk factor.

However, the study was observational, so “the findings cannot imply causation, [and just] because someone has depression, that does not mean they will go on to develop Alzheimer’s,” said Dr. Sexton, who also was not involved with the research.

Still, “these data support the idea that taking care of one’s mental health is incredibly important for overall wellbeing. For providers, it’s important to have mental health evaluation be a part of your patient’s regular checkups,” she added.

Dr. Richmond-Rakerd noted that even if mental health conditions are not a causal risk factor for dementia, “the presence of a mental health problem is still an important indicator of risk. Mental health providers may wish to target other risk factors for dementia that are more common in individuals with mental health conditions, such as social disconnection.”

The study was funded by grants from the National Institute on Aging, the U.K. Medical Research Council, the National Institute of Child Health and Development through the Duke Population Research Center, and the National Institute on Aging through the Center for Advancing Sociodemographic and Economic Study of Alzheimer’s Disease and Related Dementias.

“There could also be shared risk factors for both mental disorders and dementia, such as shared genetics, or individuals may experience a lifelong brain vulnerability that shows up as mental health problems earlier in life and shows up as dementia later in life,” she said.
 

An important risk factor

Commenting for this article, Ken Duckworth, MD, chief medical officer of the National Alliance on Mental Illness, said a major strength of the study was its longitudinal scope and large population size.

He described the study as allowing clinicians to “watch the movie,” as opposed to looking at a “snapshot” of data.

“Although you can learn things from snapshots, a large, comprehensive public health system looking at 30 years of claims – something not possible in the U.S. because of our more fragmented health care system – offers more insight,” said Dr. Duckworth, who was not involved with the research.

The investigators are “painting a picture of a correlation of risk, and to me, that’s the beginning of further inquiry,” he added. “Would preventive efforts targeting dementia, such as exercise and socialization, be helpful? It’s a great study that raises these interesting questions.”

Also commenting in an interview, Claire Sexton, DPhil, director of scientific programs and outreach at the Alzheimer’s Association, said the study “adds a wealth of data to our understanding” of mental disorders as a dementia risk factor.

However, the study was observational, so “the findings cannot imply causation, [and just] because someone has depression, that does not mean they will go on to develop Alzheimer’s,” said Dr. Sexton, who also was not involved with the research.

Still, “these data support the idea that taking care of one’s mental health is incredibly important for overall wellbeing. For providers, it’s important to have mental health evaluation be a part of your patient’s regular checkups,” she added.

Dr. Richmond-Rakerd noted that even if mental health conditions are not a causal risk factor for dementia, “the presence of a mental health problem is still an important indicator of risk. Mental health providers may wish to target other risk factors for dementia that are more common in individuals with mental health conditions, such as social disconnection.”

The study was funded by grants from the National Institute on Aging, the U.K. Medical Research Council, the National Institute of Child Health and Development through the Duke Population Research Center, and the National Institute on Aging through the Center for Advancing Sociodemographic and Economic Study of Alzheimer’s Disease and Related Dementias.
