Mental illnesses are associated with a significantly increased risk of subsequent physical diseases, new research shows.

An international team of researchers has created an “atlas” that maps the relationship between specific mental disorders and the risk of subsequent physical illnesses.

The researchers found that, following the diagnosis of a mental disorder, psychiatric patients are significantly more likely than the general population to develop potentially life-threatening conditions, including heart disease and stroke.

These findings, the investigators noted, highlight the need for better medical care in this vulnerable population. They have created a website with detailed information about the risks of specific physical ailments and the link to particular mental disorders.

“We found that women with anxiety disorders have a 50% increased risk of developing a heart condition or stroke – over 15 years, one in three women with anxiety disorders will develop these medical disorders,” lead investigator John McGrath, MD, PhD, University of Queensland’s Brain Institute, Brisbane, Australia, and Aarhus (Denmark) University, said in a statement.

“We also looked at men with substance use disorders such as alcohol-related disorders and found they have a 400% increased risk of gut or liver disorders, while over 15 years, one in five of them will develop gut or liver conditions,” he added.

The study was published in the New England Journal of Medicine.
 

New ‘atlas’

It’s well known that patients with mental disorders have decreased quality of life, increased health care utilization, and a shorter life expectancy than individuals in the general population – about 10 years for men and 7 years for women.

However, the investigators noted, previous research examining the relationship between mental disorders and medical conditions only focused on “particular pairs or a small set of mental disorders and medical conditions.”

“We needed a comprehensive study to map the links between different types of mental disorders versus different types of general medical conditions. Our study has provided this atlas,” Dr. McGrath said in an interview.

The clinical utility of such a map could provide comprehensive data on relative and absolute risks of various medical conditions after a diagnosis of a mental disorder. This information, the researchers noted, would “help clinicians and health care planners identify the primary prevention needs of their patients.”

The study included 5.9 million people born in Denmark between 1900 and 2015 and followed them from 2000 to 2016, a total of 83.9 million person-years. The researchers followed patients for up to 17 years (2000-2016) for medical diagnoses and up to 48 years (1969-2016) for diagnoses of mental disorders.

The study’s large sample size allowed investigators to assess 10 broad types of mental disorders and 9 broad categories of medical conditions that encompassed 31 specific conditions.

Categories of medical conditions included circulatory, endocrine, pulmonary, gastrointestinal, urogenital, musculoskeletal, hematologic, neurologic, and cancer. Mental disorder categories included organic disorders such as Alzheimer’s, substance abuse disorders, schizophrenia, mood disorders, neurotic disorders, eating disorders, personality disorders, developmental disorders, behavioral/emotional disorders, and intellectual disabilities.

The researchers estimated associations between 90 pairs of mental disorders and broad-category medical conditions, as well as 310 pairs of mental disorders and specific medical conditions.
 

‘Curious’ finding

Individuals with mental disorders showed a higher risk of medical conditions in 76 out of 90 specific mental disorder–medical condition pairs.

After adjusting for sex, age, calendar time, and previous coexisting mental disorders, the median hazard ratio for a subsequent medical condition was 1.37 in patients with a mental disorder.

The lowest HR was 0.82 for organic mental disorders and the broad category of cancer (95% confidence interval, 0.80-0.84), and the highest was 3.62 for eating disorders and urogenital conditions (95% CI, 3.11-4.22). On the other hand, schizophrenia was associated with a reduced risk of developing musculoskeletal conditions (HR, 0.87; 95% CI, 0.84-0.91).

Dr. McGrath described this finding as “curious” and speculated it “may be related to underlying genetic risk factors.”

One of the highest cumulative associations was for mood disorders and circulatory conditions during the first 15 years following a mood disorder diagnosis, compared with the matched reference group without a mood disorder (40.9% vs. 32.6%, respectively).

The risk of developing subsequent medical conditions after a mental disorder diagnosis did not remain steady over time. For instance, although mood disorders were associated with an increased risk of developing circulatory problems (HR, 1.32; 95% CI, 1.31-1.34), the highest risk occurred during the first 6 months following diagnosis and gradually decreased over the next 15 years (HR, 2.39; 95% CI, 2.29-2.48 and HR, 1.18; 95% CI, 1.17-1.20, respectively).

“Many people with mental disorders have unhealthy lifestyle, including low exercise, poor diet, smoking, and alcohol, which may account for the increased risk of physical illness, and also they may not seek and/or may not get quick treatment for their health conditions,” said Dr. McGrath.

Additionally, “perhaps some genetic and early life exposures, such as trauma, may increase the risk of both medical conditions and mental disorders,” he added. “We need better treatments for mental disorders, so that they do not slip into unemployment or poverty.”
 

A strong case

In a comment, Roger McIntyre, MD, professor of psychiatry and pharmacology at the University of Toronto and head of the mood disorders psychopharmacology unit, University Health Network, said that the research “really makes a strong case for the fact that persons who have mental disorders are at higher risk of chronic diseases, and it’s the chronic diseases that decrease their lifespan.”

Dr. McIntyre, who is also director of the Depression and Bipolar Support Alliance, said that the “takeaway message is that mental disorders are not just brain disorders but are multisystem disorders.”

For this reason, “the most appropriate way to provide care would be to provide a holistic approach to treat and prevent the chronic diseases that lead to increase in mortality,” recommended Dr. McIntyre, who was not involved with the current study.

The study was supported by grants from the Danish National Research Foundation, the National Health and Medical Research Council, the Novo Nordisk Foundation , the European Union’s Horizon 2020 Research and Innovation Program, the Aarhus University Research Foundation, the Lundbeck Foundation, the National Institutes of Health, the European Commission, Helsefonden, the Danish Council for Independent Research, the Independent Research Fund Denmark, the National Health and Medical Research Council of Australia, and the National Institute on Drug Abuse.

Depression is associated with decreased neurologic function and new brain lesions in patients with multiple sclerosis (MS), new research suggests.

In an observational study of more than 2500 patients with relapsing-remitting MS (RRMS), participants with self-reported depression were more likely to have worse scores on neuroperformance measures, such as processing speed tests, than their peers without depression.

At baseline, the group with depression also had greater odds of having at least one new contrast-enhancing lesion on MRI.

“Our results suggest that depression is not merely a reactive symptom but indicates increased risk of future MS disease activity,” the investigators note.

Lead author Jenny Feng, MD, clinical associate at the Mellen Center for MS Treatment and Research at Cleveland Clinic, added that depression should be routinely screened for in all patients with MS, something done routinely at her center.

“Every single patient that comes through the door with newly diagnosed MS, we refer to neuropsychology to screen for depression; and if there is depression, then we actively manage it because it does have an effect” on patients, she told Medscape Medical News.

“Depression isn’t just a neuropsychiatric disease,” Feng added. As shown in their study, “it may have effects on MS, especially with regards to performance in neurological function testing.”

The research is presented on AAN.com as part of the American Academy of Neurology 2020 Science Highlights. Because of the COVID-19 pandemic, the AAN had to cancel its 2020 annual meeting.

Associations Have Been “Unclear”

Although inflammatory, psychosocial, and neurodegenerative factors “have been hypothesized as etiologies” for why depression is commonly found in patients with MS, the full association between depression and MS disease activity “is not clear,” the investigators note.

For the current study, they assessed data from the Partners Advancing Technology and Health Solutions (MS-PATHS) database, an ongoing collaborative network of seven MS centers in the United States and three in Europe.

MS disease history and MRI data were examined, as well as 12-month scores on neuroperformance tests measuring processing speed (Symbol Digit Modalities Test), walking speed (Timed 25-Foot Walk), and manual dexterity (Nine-Hole Peg Test).

Patient-reported outcomes (PROs), as measured with the Quality of Life in Neurological Disorders (Neuro-QoL) and patient-determined disease steps, were also assessed. Depression was defined as a depression T score at baseline greater than “the 50th percentile” on the Neuro-QoL.

In the patient sample, 1333 of the participants with RRMS were classified as “not depressed” (73.7% women; mean age, 45.6 years; disease duration, 13.7 years) while 1172 were “depressed” (78.4% women; mean age, 45.9 years; disease duration, 14.3 years).

“To balance for baseline variances in the observational cohort between group with depression and group without depression, propensity score analysis was used to adjust for potential confounding factors,” the investigators report.

Worse Performance

After adjustment for baseline covariates, results showed that the depressed patients performed worse on the walking speed test (0.48; 95% confidence interval, 0.038-0.918) and processing speed test (–1.899; 95% CI, –3.548 to –0.250).

The depressed group also had increased odds at baseline of having new contrast-enhancing lesions (odds ratio, 5.89; 95% CI, 2.236-15.517). This demonstrated an “association of depression and neuroinflammatory activity” in the central nervous system, the investigators note.

At 12 months, processing speed continued to be worse in the depressed group (–1.68; 95% CI, –3.254 to –0.105).

There were trends, albeit insignificant, for decreased walking speed scores at 12 months and for decreased manual dexterity scores at both baseline and at 12 months for the participants who were depressed.

Interestingly, there were “no significant differences in PROs at month 12, despite worsening neuroperformance,” the investigators report.

“This means that patients themselves may not even realize that they were getting worse,” Feng said.

Underpowered Study?

Further results showed nonsignificant trends for increased T2 lesion volume and white matter fraction and decreased brain volume, gray matter fraction, and cortical gray matter volume at baseline and at 12 months in the depressed group.

The researchers note that study limitations include the unavailability of information on treatment compliance for depression or date of depression onset.

Feng added that because this was an observational study, other missing data included depression status for some patients at year 1 and some MRI metrics.

“So this may have been underpowered to detect some of the results. The power may have been inadequate to detect all changes,” she said.

The investigators write that future research should assess larger sample sizes with longer follow-ups and should use more advanced MRI measures, such as diffusion tensor imaging or functional MRI.

In addition, they will continue examining data from MS-PATHS. “With the newest data cut, we have new patients that we can analyze. So perhaps that can provide sufficient power to detect [more MRI] changes,” Feng said.

Unusual, Intriguing Findings

Commenting on the study for Medscape Medical News, Mark Freedman, MD, professor of neurology at the University of Ottawa and director of the Multiple Sclerosis Research Clinic at the Ottawa Hospital Research Institute, noted that he wasn’t terribly surprised” by the overall findings.

“We’ve known for years that patients who are depressed don’t do as well on our performance methods,” said Freedman, who was not involved with the research.

However, the current investigators “took a huge number of patients in this multicenter study and started using some of the statistical methods we’ve seen in the use of real-world evidence,” he noted.

“So you’re looking at some outcome measures and you have to ask yourself, ‘Why would it influence that?’ and ‘Did it happen by chance or not?’ And you ask why it is that depressed people might actually have more lesions on their MRI, which is something that is unusual,” Freedman said.

“When you start to look at this, even when you’re trying to standardize things for the differences that we know of, there are some stuff that comes out as intriguing. In general, I think those depressed patients did worse on several outcome measures that one would say, ‘That’s somewhat surprising.’ That’s why this group was very careful to not conclude absolutely that depression drives this disease. But it was consistently trending in the direction that it looks like there was more inflammatory activity in these people,” he said.

He echoed the investigators’ note that drug adherence and which depression treatment was used wasn’t controlled for; and he added that depression in the study was not based on receiving a diagnosis of clinical depression but on self-report.

Still, the patients classified as depressed “did worse. They didn’t walk as fast, which was interesting; and we know that cognitive performance is often damped because of poor concentration. But how do you get worse MRIs? This study is raising a question and [the researchers] conclude that it may be that depression might be an independent factor” for that outcome, Freedman said.

“It might be that you could get more out of a particular [MS] medicine if you pay attention to depression; and if that’s the investigators’ conclusion, and I think it is, then I certainly agree with it.”

Freedman noted that, instead of a blanket recommendation that all patients with MS should be screened for depression, he thinks clinicians, especially those at smaller centers, should focus on what’s best for treating all aspects of an individual patient.

“Don’t try to manage them if you’re not going to manage the entire picture. Looking at depression and mood and other things is very important. And if you have the capacity for an official screening, I think it’s wonderful; but not everybody does,” he said.

Feng and Freedman have disclosed no relevant financial relationships. Freedman is currently a member of the Medscape Neurology Advisory Board.

In general, I think those depressed patients did worse on several outcome measures that one would say, ‘That’s somewhat surprising.’ That’s why this group was very careful to not conclude absolutely that depression drives this disease. But it was consistently trending in the direction that it looks like there was more inflammatory activity in these people,” he said.

He echoed the investigators’ note that drug adherence and which depression treatment was used wasn’t controlled for; and he added that depression in the study was not based on receiving a diagnosis of clinical depression but on self-report.

Still, the patients classified as depressed “did worse. They didn’t walk as fast, which was interesting; and we know that cognitive performance is often damped because of poor concentration. But how do you get worse MRIs? This study is raising a question and [the researchers] conclude that it may be that depression might be an independent factor” for that outcome, Freedman said.

“It might be that you could get more out of a particular [MS] medicine if you pay attention to depression; and if that’s the investigators’ conclusion, and I think it is, then I certainly agree with it.”

Freedman noted that, instead of a blanket recommendation that all patients with MS should be screened for depression, he thinks clinicians, especially those at smaller centers, should focus on what’s best for treating all aspects of an individual patient.

“Don’t try to manage them if you’re not going to manage the entire picture. Looking at depression and mood and other things is very important. And if you have the capacity for an official screening, I think it’s wonderful; but not everybody does,” he said.

Depression is associated with decreased neurologic function and new brain lesions in patients with multiple sclerosis (MS), new research suggests.

In an observational study of more than 2500 patients with relapsing-remitting MS (RRMS), participants with self-reported depression were more likely to have worse scores on neuroperformance measures, such as processing speed tests, than their peers without depression.

At baseline, the group with depression also had greater odds of having at least one new contrast-enhancing lesion on MRI.

“Our results suggest that depression is not merely a reactive symptom but indicates increased risk of future MS disease activity,” the investigators note.

Lead author Jenny Feng, MD, clinical associate at the Mellen Center for MS Treatment and Research at Cleveland Clinic, added that depression should be routinely screened for in all patients with MS, something done routinely at her center.

“Every single patient that comes through the door with newly diagnosed MS, we refer to neuropsychology to screen for depression; and if there is depression, then we actively manage it because it does have an effect” on patients, she told Medscape Medical News.

“Depression isn’t just a neuropsychiatric disease,” Feng added. As shown in their study, “it may have effects on MS, especially with regards to performance in neurological function testing.”

The research is presented on AAN.com as part of the American Academy of Neurology 2020 Science Highlights. Because of the COVID-19 pandemic, the AAN had to cancel its 2020 annual meeting.

Associations Have Been “Unclear”

Although inflammatory, psychosocial, and neurodegenerative factors “have been hypothesized as etiologies” for why depression is commonly found in patients with MS, the full association between depression and MS disease activity “is not clear,” the investigators note.

For the current study, they assessed data from the Partners Advancing Technology and Health Solutions (MS-PATHS) database, an ongoing collaborative network of seven MS centers in the United States and three in Europe.

MS disease history and MRI data were examined, as well as 12-month scores on neuroperformance tests measuring processing speed (Symbol Digit Modalities Test), walking speed (Timed 25-Foot Walk), and manual dexterity (Nine-Hole Peg Test).

Patient-reported outcomes (PROs), as measured with the Quality of Life in Neurological Disorders (Neuro-QoL) and patient-determined disease steps, were also assessed. Depression was defined as a depression T score at baseline greater than “the 50th percentile” on the Neuro-QoL.

In the patient sample, 1333 of the participants with RRMS were classified as “not depressed” (73.7% women; mean age, 45.6 years; disease duration, 13.7 years) while 1172 were “depressed” (78.4% women; mean age, 45.9 years; disease duration, 14.3 years).

“To balance for baseline variances in the observational cohort between group with depression and group without depression, propensity score analysis was used to adjust for potential confounding factors,” the investigators report.

Worse Performance

After adjustment for baseline covariates, results showed that the depressed patients performed worse on the walking speed test (0.48; 95% confidence interval, 0.038-0.918) and processing speed test (–1.899; 95% CI, –3.548 to –0.250).

The depressed group also had increased odds at baseline of having new contrast-enhancing lesions (odds ratio, 5.89; 95% CI, 2.236-15.517). This demonstrated an “association of depression and neuroinflammatory activity” in the central nervous system, the investigators note.

At 12 months, processing speed continued to be worse in the depressed group (–1.68; 95% CI, –3.254 to –0.105).

There were trends, albeit insignificant, for decreased walking speed scores at 12 months and for decreased manual dexterity scores at both baseline and at 12 months for the participants who were depressed.

Interestingly, there were “no significant differences in PROs at month 12, despite worsening neuroperformance,” the investigators report.

“This means that patients themselves may not even realize that they were getting worse,” Feng said.

Underpowered Study?

Further results showed nonsignificant trends for increased T2 lesion volume and white matter fraction and decreased brain volume, gray matter fraction, and cortical gray matter volume at baseline and at 12 months in the depressed group.

The researchers note that study limitations include the unavailability of information on treatment compliance for depression or date of depression onset.

Feng added that because this was an observational study, other missing data included depression status for some patients at year 1 and some MRI metrics.

“So this may have been underpowered to detect some of the results. The power may have been inadequate to detect all changes,” she said.

The investigators write that future research should assess larger sample sizes with longer follow-ups and should use more advanced MRI measures, such as diffusion tensor imaging or functional MRI.

In addition, they will continue examining data from MS-PATHS. “With the newest data cut, we have new patients that we can analyze. So perhaps that can provide sufficient power to detect [more MRI] changes,” Feng said.

Unusual, Intriguing Findings

Commenting on the study for Medscape Medical News, Mark Freedman, MD, professor of neurology at the University of Ottawa and director of the Multiple Sclerosis Research Clinic at the Ottawa Hospital Research Institute, noted that he wasn’t terribly surprised” by the overall findings.

“We’ve known for years that patients who are depressed don’t do as well on our performance methods,” said Freedman, who was not involved with the research.

However, the current investigators “took a huge number of patients in this multicenter study and started using some of the statistical methods we’ve seen in the use of real-world evidence,” he noted.

“So you’re looking at some outcome measures and you have to ask yourself, ‘Why would it influence that?’ and ‘Did it happen by chance or not?’ And you ask why it is that depressed people might actually have more lesions on their MRI, which is something that is unusual,” Freedman said.

“When you start to look at this, even when you’re trying to standardize things for the differences that we know of, there are some stuff that comes out as intriguing. In general, I think those depressed patients did worse on several outcome measures that one would say, ‘That’s somewhat surprising.’ That’s why this group was very careful to not conclude absolutely that depression drives this disease.

In 2019, the US Preventive Services Task Force published 19 recommendation statements on 11 topics. Two of the topics are new; 9 are topics the Task Force had previously reviewed and has updated (TABLE 1). Three of these topics have been covered in Practice Alert podcasts (mdedge.com/familymedicine) and will not be discussed here: risk assessment, genetic counseling, and genetic testing for breast cancer susceptibility gene mutations (October 2019); medications to reduce the risk of breast cancer (December 2019); and preexposure prophylaxis to prevent HIV infections (January 2020).

Of the 19 recommendation statements made in 2019 (TABLE 2), 5 were rated “A” and 5 were “B,” meaning the evidence shows that benefits outweigh harms and these interventions should be offered in primary care practice. There were 5 “D” recommendations for interventions that should not be offered because they are either ineffective or harms exceed benefits. There were 3 “I” statements on interventions having insufficient evidence on benefits or harms to warrant a recommendation. Only 1 recommendation was rated “C” (selectively offer based on individual factors); this assessment is the hardest one to interpret and implement. Keep in mind that all “A” and “B” recommendations must be covered by commercial health plans with no out-of-pocket cost to the patient (ie, no co-pay or deductible).

New recommendation on preventing perinatal depression

One of 2 new topics reviewed in 2019 was the prevention of perinatal depression. (As noted, the other on preexposure prophylaxis to prevent HIV infection has already been covered in a Practice Alert podcast.) The Task Force found that the prevalence of depression is estimated at 8.9% among pregnant women and 37% at any point in the first year postpartum.¹

Depression during pregnancy and the postpartum period is associated with adverse effects on the mother and infant, including higher rates of suicide and suicidal ideation and thoughts of harming the infant.¹ Women with perinatal depression are also more likely to exhibit significantly lower levels of positive maternal behaviors, such as praising and playing with their child,² and higher rates of negative maternal behaviors.² Perinatal depression is also associated with increased rates of preterm birth and low birth weight.³

Mothers with postpartum depression have higher rates of early termination of breast feeding and lower adherence for recommended child preventive services including vaccination.¹ Children of mothers with perinatal depression develop more behavior problems, have lower cognitive functioning, and have an increased risk of psychiatric disorders than do children of mothers without this condition.^4,5

A number of risk factors are associated with perinatal depression, but no screening tool was found to have enough predictive value to be recommended. In deciding who should receive an offer or referral for counseling, the Task Force recommends as a practical approach providing “counseling interventions to women with 1 or more of the following: a history of depression, current depressive symptoms (that do not reach a diagnostic threshold), certain socioeconomic risk factors such as low income or adolescent or single parenthood, recent intimate partner violence, or mental health-related factors such as elevated anxiety symptoms or a history of significant negative life events.”¹

There is no conclusive evidence to guide timing of counseling interventions, but most studies reviewed started them in the second trimester. These studies included cognitive behavioral therapy and interpersonal therapy and involved counseling sessions that ranged from 4 to 20 sessions and lasted for 4 to 70 weeks. They involved group and individual sessions, mostly in-person visits, and were provided by a variety of health professionals.⁶

Continue to: The studies reviewed showed...

The studies reviewed showed that counseling interventions reduced the likelihood of developing depression symptoms by 39%, with a number needed to treat of 13.5.⁶ Studies that looked at pregnancy and maternal and infant clinical outcomes were mixed but usually found little to no difference with counseling.⁶ Even so, the Task Force felt that a reduction in depression itself was enough to warrant a “B” recommendation.

Screening for abdominal aortic aneurisms

Ultrasound is underused in screening for abdominal aortic aneurisms (AAA) and preventing death from their rupture. (See “Whom should you screen for abdominal aortic aneurysm?”) The prevalence of AAA is the United States is unknown; in other western countries it varies from 1.2% to 3.3% in men and is declining due to decreased rates of smoking, the primary risk factor.

The risk of AAA rupture is related to the size of the aneurism, and surgical repair (either endovascular or open repair) is usually reserved for lesions > 5.5 cm in diameter or for smaller ones that are rapidly increasing in size. The standard of care for most aneurysms < 5.5 cm is to periodically monitor growth ­using ultrasound.

The 2019 recommendations on AAA screening are essentially the same as those made in 2004; evaluation of new evidence supported the previous recommendations. The Task Force recommends one-time screening for men ages 65 to 75 years who have ever smoked (B recommendation). Selective screening is recommended for men in this age group who have never smoked, based mainly on personal factors such as a family history of AAA, the presence of other arterial aneurisms, and the number of risk factors for cardiovascular disease (C recommendation).

The Task Force recommends against screening women ages 65 to 75 years with no history of smoking or family history of AAA, while the evidence was felt to be insufficient to make a recommendation for women in this age range who have either risk factor. This is problematic for family physicians since women with these risk factors are at increased risk of AAA compared with women without risk factors.⁸ And aneurisms in women appear to rupture more frequently at smaller sizes, although at a later age than in men.⁸ Operative mortality is also higher in women than in men⁸ and there is no direct evidence that screening improves outcomes for women.

Continue to: Screening for asymptomatic bacteriuria

The Task Force re-examined and reconfirmed its previous recommendations on screening for asymptomatic bacteriuria in adults. It recommends in favor of it for pregnant women, using a urine culture to screen, and against it for all other adults. There is good evidence that treating screen-detected asymptomatic bacteriuria in pregnant women reduces the incidence of pyelonephritis in pregnancy.

The Task Force made this a “B” recommendation based on a lower prevalence of pyelonephritis found in more recent studies, making the overall magnitude of benefits moderate. There is also good evidence that treating asymptomatic bacteriuria in nonpregnant adults offers no benefits.⁹ The Task Force has re-examined this topic 5 times since 1996 with essentially the same results.

Screening for elevated lead levels in children and pregnant women

In 2019 the Task Force changed its 2006 recommendation on screening for elevated lead levels. The earlier recommendation advised against screening both children ages 1 to 5 years and pregnant women at average risk for elevated blood lead levels. In 2006 the Task Force also felt that evidence was insufficient to make a recommendation regarding children ages 1 to 5 years at elevated risk.

The Task Force now believes the evidence is insufficient to make a recommendation for all children ages 1 to 5 years and for pregnant women, thus moving from a “D” to an “I” recommendation for children and pregnant women with average risk. Even though there is little evidence to support screening for elevated lead levels in children ages 1 to 5 years and in pregnant women, the Task Force apparently did not feel comfortable recommending against testing, given that the cutoff for elevated blood lead levels has been lowered from 10 to 5 mcg/dL and that other sources of lead may now be more prevalent than in 2006.¹⁰

Perinatal counseling of women with known risks of depression reduces the likelihood of depressive symptoms by 39%.

Remember that the Medicaid Early and Periodic Screening, Diagnostic, and Treatment program requires that all children receive a blood lead test twice, at ages 12 and 24 months, and that previously unscreened children ages 36 to 72 months must be tested once.

Continue to: Additional updates with no recommendation changes

Four other topics were re-examined by the Task Force in 2019, resulting in no significant changes to recommendations (TABLE 2):

• Screen for hepatitis B infection in pregnant women at the first prenatal visit (A recommendation; updated from 2009).
• Screen for HIV infection in adolescents and adults ages 15 to 65 years, and in those younger and older who are at high risk, and during pregnancy (A recommendation; updated from 2013).
• Provide topical medication for all newborns to prevent gonococcal ophthalmia neonatorum (A recommendation; first recommendation in 1996, updated in 2005 and 2011).
• Avoid screening for pancreatic cancer in asymptomatic adults (D recommendation; updated from 2004).

Affirmation of USPSTF’s value

In only 1 out of 9 reassessments of past topics did the Task Force modify its previous recommendations in any significant way. This demonstrates that recommendations will usually stand the test of time if they are made using robust, evidence-based methods (that consider both benefits and harms) and they are not made when evidence is insufficient. That only 2 new topics could be addressed in 2019 may reflect a need for more resources for the Task Force.

In 2019, the US Preventive Services Task Force published 19 recommendation statements on 11 topics. Two of the topics are new; 9 are topics the Task Force had previously reviewed and has updated (TABLE 1).

Perinatal counseling of women with known risks of depression reduces the likelihood of depressive symptoms by 39%.

Remember that the Medicaid Early and Periodic Screening, Diagnostic, and Treatment program requires that all children receive a blood lead test twice, at ages 12 and 24 months, and that previously unscreened children ages 36 to 72 months must be tested once.

Continue to: Additional updates with no recommendation changes

Four other topics were re-examined by the Task Force in 2019, resulting in no significant changes to recommendations (TABLE 2):

• Screen for hepatitis B infection in pregnant women at the first prenatal visit (A recommendation; updated from 2009).
• Screen for HIV infection in adolescents and adults ages 15 to 65 years, and in those younger and older who are at high risk, and during pregnancy (A recommendation; updated from 2013).
• Provide topical medication for all newborns to prevent gonococcal ophthalmia neonatorum (A recommendation; first recommendation in 1996, updated in 2005 and 2011).
• Avoid screening for pancreatic cancer in asymptomatic adults (D recommendation; updated from 2004).

Affirmation of USPSTF’s value

In only 1 out of 9 reassessments of past topics did the Task Force modify its previous recommendations in any significant way. This demonstrates that recommendations will usually stand the test of time if they are made using robust, evidence-based methods (that consider both benefits and harms) and they are not made when evidence is insufficient. That only 2 new topics could be addressed in 2019 may reflect a need for more resources for the Task Force.

Patients with atrial fibrillation, even those on oral anticoagulant therapy, developed clinically silent brain infarctions at a striking rate of close to 3% per year, according to results from SWISS-AF, a prospective of study of 1,227 Swiss patients followed with serial MR brain scans over a 2 year period.

The results also showed that these brain infarctions – which occurred in 68 (5.5%) of the atrial fibrillation (AFib) patients, including 58 (85%) who did not have any strokes or transient ischemic attacks during follow-up – appeared to represent enough pathology to link with a small but statistically significant decline in three separate cognitive measures, compared with patients who did not develop brain infarctions during follow-up.

“Cognitive decline may go unrecognized for a long time in clinical practice because usually no one tests for it,” plus “the absolute declines were small and probably not appreciable” in the everyday behavior of affected patients, David Conen, MD, said at the annual scientific sessions of the Heart Rhythm Society, held online because of COVID-19. But “we were surprised to see a significant change after just 2 years. We expect much larger effects to develop over time,” he said during a press briefing.

Another key finding was that roughly half the patients had large cortical or noncortical infarcts, which usually have a thromboembolic cause, but the other half had small noncortical infarcts that likely have a different etiology involving the microvasculature. Causes for those small infarcts might include localized atherosclerotic disease or amyloidosis, proposed Dr. Conen, a cardiologist at McMaster University, Hamilton, Ont.

This finding also suggests that, as a consequence, anticoagulation alone may not be enough to prevent this brain damage in Afib patients. “It calls for a more comprehensive approach to prevention,” with attention to atherosclerotic cardiovascular disease risk factors in AFib patients, including interventions that address hypertension, diabetes, hyperlipidemia, and smoking cessation. “Anticoagulation in AFib patients is critical, but it also is not enough,” Dr. Conen said.

These data “are very important. The two pillars for taking care of AFib patients have traditionally been to manage the patient’s stroke risk and to treat symptoms. Dr. Conen’s data suggest that simply starting anticoagulation is not sufficient, and it stresses the importance of continued management of hypertension, diabetes, and other medical and social issues,” commented Fred Kusumoto, MD, director of heart rhythm services at the Mayo Clinic in Jacksonville, Fla.

“The risk factors associated with the development of cardiovascular disease are similar to those associated with the development of AFib and heart failure. It is important to understand the importance of managing hypertension, diabetes, and obesity; encouraging exercise and a healthy diet; and stopping smoking in all AFib patients as well as in the general population. Many clinicians have not emphasized the importance of continually addressing these behaviors,” Dr. Kusumoto said in an interview.

The SWISS-AF (Swiss Atrial Fibrillation Cohort) study enrolled 2,415 AFib patients at 14 Swiss centers during 2014-2017, and obtained both a baseline brain MR scan and baseline cognitive-test results for 1,737 patients (J Am Coll Cardiol. 2019 Mar;73[9]:989-99). Patients retook the cognitive tests annually, and 1,227 had a second MR brain scan after 2 years in the study, the cohort that supplied the data Dr. Conen presented. At baseline, these patients averaged 71 years of age, just over a quarter were women, and 90% were on an oral anticoagulant, with 84% on an oral anticoagulant at 2-year follow-up. Treatment split roughly equally between direct-acting oral anticoagulants and vitamin K antagonists like warfarin.

Among the 68 patients with evidence for an incident brain infarct after 2 years, 59 (87%) were on treatment with an OAC, and 51 (75%) who were both on treatment with a direct-acting oral anticoagulant and developed their brain infarct without also having a stroke or transient ischemic attack, which Dr. Conen called a “silent event.” The cognitive tests that showed statistically significant declines after 2 years in the patients with silent brain infarcts compared with those without a new infarct were the Trail Making Test parts A and B, and the animal-naming verbal fluency test. The two other tests applied were the Montreal Cognitive Assessment and the Digital Symbol Substitution Test.

Results from several prior studies also indicated a relationship between AFib and cognitive decline, but SWISS-AF is “the largest study to rigorously examine the incidence of silent brain infarcts in AFib patients,” commented Christine M. Albert, MD, chair of cardiology at the Smidt Heart Institute of Cedars-Sinai Medical Center in Los Angeles. “Silent infarcts could be the cause, at least in part, for the cognitive decline and dementia associated with AFib,” she noted. But divining the therapeutic implications of the finding will require further investigation that looks at factors such as the impact of anticoagulant type, other treatment that addresses AFib such as ablation and rate control, the duration and type of AFib, and the prevalence of hypertension and other stroke risk factors, she said as a designated discussant for Dr. Conen’s report.

SWISS-AF received no commercial funding. Dr. Conen has been a speaker on behalf of Servier. Dr. Kusumoto had no disclosures. Dr. Albert has been a consultant to Roche Diagnostics and has received research funding from Abbott, Roche Diagnostics, and St. Jude Medical.

The serum level of neurofilament light chain (sNfL) around the time of multiple sclerosis (MS) diagnosis is associated with long-term clinical disease progression, with higher baseline levels a sensitive marker of subsequent poor clinical outcomes, research suggests. The study showed that patients with higher sNfL within 5 years of MS diagnosis had a higher risk of long term-clinical disability and higher risk of developing progressive MS. The level of sNfL also predicted the rate of increase over time in the Expanded Disability Status Scale (EDSS).

Serum NfL levels can provide “useful information in both directions, adding to both an overall reassuring picture or worrying picture both at first presentation and then on subsequent visits,” said Simon Thebault, MBBCh, a neurology resident at the University of Ottawa and the Ottawa Hospital Research Institute, Canada.

This research was presented online as part of the 2020 American Academy of Neurology Science Highlights.
 

Prognostication from day one

Many studies have shown a correlation between MS disease activity (clinical relapses, EDSS progression, MRI lesions) and elevated sNfL. Other studies have also looked at the prognostic value of NfL in serum and cerebrospinal fluid (CSF), but the data are limited by the lack of long-term biobanked samples and subsequent follow-up, Dr. Thebault explained.

The new study took advantage of the Ottawa MS biobank, which contains carefully frozen and stored samples from more than 3,000 patients with MS going back up to 25 years.

The team identified patients with serum collected within 5 years of first MS symptom onset (baseline) who were followed for a median of 18.9 years (range 15.0 to 27.0 years). They quantified levels of sNfL in 67 patients and 37 matched controls.

In patients with MS, the median baseline sNfL level was 10.1 pg/mL – 38.5% higher than the median level in controls (7.26 pg/mL, P = 0.004).

The baseline sNfL level was “most helpful as a sensitive predictive marker to rule out disease progression,” the researchers reported in their meeting abstract.

Patients with baseline sNfL levels less than 7.62 pg/mL were 4.3 times less likely to develop significant disability (EDSS score ≥ 4; P = 0.001) and 7.1 times less likely to develop progressive MS by end of follow-up (P = 0.054).

The most rapid disease progression was seen in patients with the highest baseline NfL levels (3rd-tertile, > 13.2 pg/mL). Higher baseline sNfL level was associated with faster rate of EDSS progression even after adjusting for confounders of age, sex, and disease-modifying treatment.

“We were able to show that serum neurofilament levels collected very early in the disease, usually at the time of first diagnosis, were predictive of the clinical progression [by EDSS score] and the risk of evolving to secondary progressive MS on average 19 years later,” Dr. Thebault said. A baseline level less than 7.6 pg/mL was “reassuring.”

“Prognostication in MS from day one is important,” he emphasized.

“If we know someone is on a bad trajectory, neurologists might recommend more aggressive therapies up front. Equally, if a patient has a very reassuring picture, then maybe it is more appropriate to start with safer treatments [the so called ‘platform therapies’] that may serve a patient well for many years, as they did for many in the years before higher-efficacy therapies were available,” Dr. Thebault said.

“In the hands of an expert MS neurologist who understands both the pearls and pitfalls of this test ... serum neurofilament is already a useful clinical tool, and we have implemented it in our daily practice in Ottawa,” he concluded.
 

Noteworthy study

Commenting on the study, Asaff Harel, MD, neurologist at Lenox Hill Hospital in New York City, said the findings in this study are “noteworthy, as there is a relative lack of effective prognostic biomarkers in the field of MS.”

“It remains to be seen whether this improves risk stratification of patients above what can be achieved by looking at other prognostic factors, such as age, gender, baseline EDSS, and severity and frequency of relapses during early disease course,” Dr. Harel cautioned.

“This was a relatively small study and further research is necessary,” Dr. Harel added. It’s also worth noting, he said, that out of the 67 patients who met criteria to be included in the study (i.e., those with blood samples taken during “early MS,” more than 15 years ago), almost half were lost to follow-up, which could potentially open the study to error.

It is also “unclear whether early NfL level is a better prognostic marker than severity of early disease course and baseline EDSS, both of which were not addressed in the study, and this will be interesting to determine in the future,” Dr. Harel commented.

Funding for the study was provided by The Ottawa Hospital Pilot Project Grant. Thebault and Harel have disclosed no relevant financial relationships.

Patients with epilepsy may report less than half of their seizures to clinicians, according to survey results presented online as part of the 2020 American Academy of Neurology Science Highlights.

Clinicians, for their part, may underestimate the number of seizures that go unreported. This disconnect may contribute to complacency about epilepsy treatment regimens among patients, caregivers, and health care professionals (HCPs), despite continuations in seizures. “Improved reporting of all seizure occurrences and more frequent discussion of potential treatment changes, initiated by all groups, may be needed to optimize treatment outcomes,” said Patricia E. Penovich, MD, a neurologist at Minnesota Epilepsy Group in St. Paul, and colleagues.

This disconnect may contribute to complacency about epilepsy treatment regimens among patients, caregivers, and health care professionals (HCPs), despite continuations in seizures. “Improved reporting of all seizure occurrences and more frequent discussion of potential treatment changes, initiated by all groups, may be needed to optimize treatment outcomes,” said Patricia E. Penovich, MD, a neurologist at Minnesota Epilepsy Group in St. Paul, and colleagues.

A new meta-analysis has concluded that the benefit of statin therapy in the prevention of ischemic stroke “greatly exceeds” the risk for intracerebral hemorrhage (ICH). The meta-analysis was presented online as part of the 2020 American Academy of Neurology Science Highlights.

Coauthor Abhi Pandhi, MD, the University of Tennessee Health Science Center, Memphis, explained that some previous studies have suggested that statin therapy may be associated with an increased risk for ICH, especially at higher doses. Other studies, however, have failed to confirm this and have shown an increase in cardiovascular events if statins are stopped.

To look further into this issue, Dr. Pandhi and colleagues conducted a meta-analysis of 19 clinical studies involving patients who had a history of cardiovascular or cerebrovascular events and who had been treated with statins. A total of 35,842 patients were included.

Results showed that statin use was not significantly associated with the risk for combined primary and secondary ICH (relative risk, 1.03; 95% confidence interval, 0.85–1.08). But the risk for cerebral ischemia (stroke and transient ischemic attack) was significantly lower in those who received statins (RR, 0.79; 95% CI, 0.61–0.87).

“Overall, we found no effect of statins on the risk of ICH, and benefits on reducing ischemic events are clear,” Dr. Pandhi said.
 

Increased secondary ICH?

However, a sensitivity analysis showed a trend toward a higher risk for secondary ICH among those who were assigned to statin treatment (odds ratio, 1.87; 95% CI, 0.91–3.86).

“While this may suggest an increased risk of secondary ICH, when we look at the big picture, putting all the data together, and given that ischemic events are far more common than ICH, the risk of stopping statins and losing the protection against ischemic events is probably greater than any harm even in patients with underlying risk factors for ICH,” Dr. Pandhi concluded.

Commenting on the study, Michael Szarek, PhD, who has also conducted research in this field, said: “The results of this meta-analysis appear to be consistent with individual randomized trials of statins in patients with cerebrovascular disease that have shown clear benefit in terms of ischemic stroke or TIA and potential harm in terms of hemorrhagic stroke.”

Dr. Szarek is chair and professor in the Department of Epidemiology and Biostatistics at the SUNY Downstate Health Sciences University, New York City.

“However, the much greater frequency of ischemic events, coupled with benefits in coronary and peripheral vascular territories, suggest the risk/benefit of statin treatment remains favorable in this patient population, with the possible exception of patients with a history of hemorrhagic stroke,” he added.

Also commenting on this latest meta-analysis, Pamela Rist, ScD, associate epidemiologist at Brigham and Women’s Hospital and assistant professor of medicine at Harvard Medical School, Boston, who has also authored studies in this area, said the results of this study seem similar to prior results from meta-analyses of clinical trials.

“It will be interesting to see the full manuscript to learn more about the sensitivity analyses they conducted and why they may have observed a nonsignificant increased risk of secondary ICH among some individuals using statins,” Dr. Rist added.

“Based on prior published meta-analyses of statin use and ICH, any potential increase in risk of hemorrhagic stroke is probably outweighed by the reduction in ischemic stroke and other cardiovascular events,” she concluded.

Dr. Pandhi has disclosed no relevant financial relationships.

Starting treatment for relapsing-remitting multiple sclerosis (MS) with high-efficacy therapy (HET) is associated with lower long-term disability compared with a step-wise increase to reach more aggressive treatment later, new research suggests. However, there is a trade-off: In this study of nearly 300 patients, those treated with initial HET experienced more disease activity in the first 2 years than other participants.

The HET benefit emerged between 2 and 10 years into the study. For example, the mean Expanded Disability Status Scale (EDSS) scores were significantly lower at 6 years in the early, aggressive treatment group than in the later HET group (2.4 vs 3.3, respectively).

“Treatment decisions made around the time of diagnosis will affect long-term outcomes,” said lead author Anna He, MBBS, currently with the Department of Clinical Neuroscience, Karolinska Institute, Stockholm, and the UCL Queen Square Institute of Neurology in London.

Using the most efficacious disease-modifying therapies from the start minimizes disability, “whereas those patients escalating to high-efficacy disease-modifying therapies later do not seem to catch up to those who commenced earlier,” Dr. He said.

“Patients and clinicians should be aware of this when choosing treatment in early MS,” she added.

This research was presented online as part of the 2020 American Academy of Neurology Science Highlights.
 

Patient-centered outcome

Instead of measures of brain volume, lesion count, serum neurofilament, or other biomarkers that are mainly of interest to clinicians and scientists, “the main outcome of interest to our patients is their disability,” Dr. He said. “The first question they ask at diagnosis is usually along the lines of: ‘What will my disability be in 10 years?’ ”

“This is what matters to patients and is fundamentally what motivated this study,” Dr. He added.

The investigators searched international MS registries for patients with relapsing-remitting MS starting HET, which included rituximab, ocrelizumab, mitoxantrone, alemtuzumab, or natalizumab.

They compared 117 participants who started HET within the first 2 years of clinical disease onset (the early group) with 181 participants who started HET after more than 4 years (the late group). All were followed for a median of 7.4 years (range, 6.4 to 8.6 years).

Difference in EDSS scores from baseline was the primary outcome. Both cohorts began the study with a mean EDSS score of 2.4, but between-group differences were significant at 10 years.

The secondary outcome of cumulative hazard of disability progression was higher in the early-treatment group from baseline to 2 years. Between the period of 2 and 10 years, the inverse was true.

In patients with highly active MS, “early exposure to high efficacy therapies is recommended,” Dr. He noted.

“We can already affect our patients’ lives enormously by utilizing our current toolbox in the most optimal way. It is our task to optimize this in a data-driven manner.”

Going forward, Dr. He plans to look at other outcomes, including patient-reported quality of life and health economic measures, and to take a different approach to future research.

Rather than assess MS outcomes from a disease-biology perspective, “I will be looking at MS outcomes from the perspective of its key stakeholders—the individual and society,” and the factors that influence them, Dr. He said.
 

Confirmatory evidence?

Commenting on the findings, Robert Gross, MD, a neurologist at the Rocky Mountain MS Center at the University of Colorado Denver in Aurora, said it is “hard to believe we are still having this debate” about earlier versus later HET.

There are now “numerous studies, including head-to-head trials and large cohort studies, showing superiority of highly efficacious agents to older disease-modifying therapies of more limited efficacy, as well as better outcomes with early versus delayed use of high-efficacy therapy,” said Dr. Gross, who was not involved with the current research.

“This study further adds to the evidence that we should be preferentially starting folks with relapsing-remitting MS right away on high-efficacy therapy, rather than waiting for relapses and disease progression to occur,” he added.

Drs. He and Gross have disclosed no relevant financial relationships.

Diastolic dysfunction, a common and often undiagnosed condition in older individuals, could be contributing to the increasing burden of cognitive decline, a new study suggests. “We found people with worsening diastolic dysfunction have more white matter hyperintensities on brain imaging and greater difficulty with executive functioning, suggesting that diastolic dysfunction is a common modifiable risk factor for cognitive impairment,” said lead author Alicia S. Parker, MD. Dr. Parker is assistant professor of cognitive and behavioral neurology at the Glenn Biggs Institute for Alzheimer’s and Neurodegenerative Diseases, University of Texas Health, San Antonio.

“This is an entirely new finding. While there have been some small studies suggesting a link between diastolic dysfunction and a reduction in working memory, this is by far the largest dataset on this topic and the first study that has included brain imaging and neuropsychological measures,” she said.

“Diastolic dysfunction is very common in the older population, and we need to do more to find it and treat it to help prevent or reduce cognitive decline,” Dr. Parker added.

This research is being presented online as part of the 2020 American Academy of Neurology Science Highlights.

Dr. Parker explained that systolic dysfunction is known to have a major effect on cardiovascular outcomes and has been found to be associated with cognitive decline. Proposed mechanisms for cognitive decline in patients with systolic dysfunction include low cardiac output, embolic infarctions, and hypoxic changes, among others.

“There is increasing interest in analyzing the influence of diastolic dysfunction on cardiovascular outcomes, and the effects of diastolic dysfunction on cognition are not currently well delineated, which this study seeks to address,” she added.

“While these results are new, they are not surprising. In general, we are finding more and more that heart health is connected to brain health,” she commented.

Dr. Parker and her colleagues started the current research after noticing in clinic that among patients with significant diastolic dysfunction, there were often changes on brain MRI imaging, and the patients often had trouble with executive function. “The effect of diastolic dysfunction on cognition has not been well characterized, so we wanted to look at this,” she said.

The investigators analyzed data from the Framingham Heart Study Offspring Cohort at examination 8, collected between 2005 and 2008. The study sample included 1,438 individuals older than 55 years who had undergone neuropsychological assessment and echocardiographic diastolic measurement. Systolic measurements were normal for the participants, and they did not currently have dementia, stroke, or other neurologic illness.

Results showed that increasing E/E’ ratio (the ratio of mitral peak velocity of early filling to early diastolic mitral annular velocity) indicated increasing diastolic dysfunction and was associated with an increase in the incidence of mild cognitive impairment (hazard ratio, 1.29; 95% confidence interval, 1.01-1.66; P < .043).

An increased E/E’ ratio was associated with increased executive function impairment in the “similarities” (beta, –0.29; P < .002) and “phonemic fluency” (–1.28; P < .001) tasks.

Participants with moderate to severe diastolic dysfunction were more impaired with respect to both similarities (–0.62; P < .046) and phonemic fluency (–2.60; P < .023).

Data from 1,217 participants showed that among those with mild diastolic dysfunction, there was a trend toward an increase in white matter hyperintensities (0.11; P < .105). For participants with moderate to severe diastolic dysfunction, white matter hyperintensities were increased (0.30; P < 0.001).

The results were unchanged after the researchers adjusted for many other predictors of cognitive decline affecting diastolic function.

The researchers conclude: “As cerebral small vessel disease clinically presents with executive dysfunction, these results align well.” They add that replication in additional cohorts and analyses of cognition in treatment trials of diastolic dysfunction are warranted.

Earlier interventions

Commenting on the study, Marco R. Di Tullio, MD, professor of medicine and Columbia University Medical Center, New York City, who is also studying the relationship between subclinical cardiac abnormalities and cognition, said: “This is a promising area of research, as it might allow us to uncover novel risk factors for cognitive decline at an early stage, before the development of clinically manifest cardiac disease, which might allow earlier interventions to decrease or delay the onset of cognitive decline.”

Dr. Di Tullio added that he would like to know more about the interaction between diastolic dysfunction, MRI abnormalities, and cognitive impairment risk. “In this study, MRI abnormalities and cognitive impairment are treated as separate outcomes, with diastolic dysfunction being the exposure for each of them. An additional analysis of the association between diastolic dysfunction and cognitive impairment stratified by presence or absence of brain MRI findings would have been interesting.”

Dr. Parker responded that this is an area of investigation. “We suspect that our cognitive findings would not be explained by any one MRI measure, though a comprehensive examination of MRI findings would be of benefit. The thought that there may be a reversible cardiac abnormality that does not have a structural brain imaging correlate on MRI is an interesting possibility,” she said.

Dr. Di Tullio also pointed out that at present, there is no specific treatment for diastolic dysfunction other than to address some the conditions that predispose to it, such as hypertension and atrial fibrillation.

“We completely agree that specific treatments are an area of investigation and that treatment is therefore targeted at associated modifiable conditions,” Dr. Parker replied.

With regard to more specific estimates of the prevalence of diastolic dysfunction, Dr. Parker cites another Framingham analysis that involved 2,355 persons without any prevalent cardiovascular conditions. That study found that diastolic dysfunction was rare until 50 years of age and then gradually increased with age.

About 5% of people in their 50s had mild diastolic dysfunction, and about 3% had moderate to severe diastolic dysfunction. Among persons in their 60s, about 18% had mild and 5% had severe diastolic dysfunction. Among persons in their 70s, mild diastolic dysfunction occurred in 35%, and moderate to severe disease was present in 18%; and in persons older than 80 years, nearly half had mild and about 20% had moderate to severe diastolic dysfunction.

With regard to more specific estimates of the prevalence of diastolic dysfunction, Dr. Parker cites another Framingham analysis that involved 2,355 persons without any prevalent cardiovascular conditions. That study found that diastolic dysfunction was rare until 50 years of age and then gradually increased with age.

About 5% of people in their 50s had mild diastolic dysfunction, and about 3% had moderate to severe diastolic dysfunction. Among persons in their 60s, about 18% had mild and 5% had severe diastolic dysfunction. Among persons in their 70s, mild diastolic dysfunction occurred in 35%, and moderate to severe disease was present in 18%; and in persons older than 80 years, nearly half had mild and about 20% had moderate to severe diastolic dysfunction.

Diastolic dysfunction, a common and often undiagnosed condition in older individuals, could be contributing to the increasing burden of cognitive decline, a new study suggests. “We found people with worsening diastolic dysfunction have more white matter hyperintensities on brain imaging and greater difficulty with executive functioning, suggesting that diastolic dysfunction is a common modifiable risk factor for cognitive impairment,” said lead author Alicia S. Parker, MD. Dr. Parker is assistant professor of cognitive and behavioral neurology at the Glenn Biggs Institute for Alzheimer’s and Neurodegenerative Diseases, University of Texas Health, San Antonio.

“This is an entirely new finding. While there have been some small studies suggesting a link between diastolic dysfunction and a reduction in working memory, this is by far the largest dataset on this topic and the first study that has included brain imaging and neuropsychological measures,” she said.

“Diastolic dysfunction is very common in the older population, and we need to do more to find it and treat it to help prevent or reduce cognitive decline,” Dr. Parker added.

This research is being presented online as part of the 2020 American Academy of Neurology Science Highlights.

Dr. Parker explained that systolic dysfunction is known to have a major effect on cardiovascular outcomes and has been found to be associated with cognitive decline. Proposed mechanisms for cognitive decline in patients with systolic dysfunction include low cardiac output, embolic infarctions, and hypoxic changes, among others.

“There is increasing interest in analyzing the influence of diastolic dysfunction on cardiovascular outcomes, and the effects of diastolic dysfunction on cognition are not currently well delineated, which this study seeks to address,” she added.

“While these results are new, they are not surprising. In general, we are finding more and more that heart health is connected to brain health,” she commented.

Dr. Parker and her colleagues started the current research after noticing in clinic that among patients with significant diastolic dysfunction, there were often changes on brain MRI imaging, and the patients often had trouble with executive function. “The effect of diastolic dysfunction on cognition has not been well characterized, so we wanted to look at this,” she said.

The investigators analyzed data from the Framingham Heart Study Offspring Cohort at examination 8, collected between 2005 and 2008. The study sample included 1,438 individuals older than 55 years who had undergone neuropsychological assessment and echocardiographic diastolic measurement. Systolic measurements were normal for the participants, and they did not currently have dementia, stroke, or other neurologic illness.

Results showed that increasing E/E’ ratio (the ratio of mitral peak velocity of early filling to early diastolic mitral annular velocity) indicated increasing diastolic dysfunction and was associated with an increase in the incidence of mild cognitive impairment (hazard ratio, 1.29; 95% confidence interval, 1.01-1.66; P < .043).

An increased E/E’ ratio was associated with increased executive function impairment in the “similarities” (beta, –0.29; P < .002) and “phonemic fluency” (–1.28; P < .001) tasks.

Participants with moderate to severe diastolic dysfunction were more impaired with respect to both similarities (–0.62; P < .046) and phonemic fluency (–2.60; P < .023).

Data from 1,217 participants showed that among those with mild diastolic dysfunction, there was a trend toward an increase in white matter hyperintensities (0.11; P < .105). For participants with moderate to severe diastolic dysfunction, white matter hyperintensities were increased (0.30; P < 0.001).

The results were unchanged after the researchers adjusted for many other predictors of cognitive decline affecting diastolic function.

The researchers conclude: “As cerebral small vessel disease clinically presents with executive dysfunction, these results align well.” They add that replication in additional cohorts and analyses of cognition in treatment trials of diastolic dysfunction are warranted.

Earlier interventions

Commenting on the study, Marco R. Di Tullio, MD, professor of medicine and Columbia University Medical Center, New York City, who is also studying the relationship between subclinical cardiac abnormalities and cognition, said: “This is a promising area of research, as it might allow us to uncover novel risk factors for cognitive decline at an early stage, before the development of clinically manifest cardiac disease, which might allow earlier interventions to decrease or delay the onset of cognitive decline.”

Dr. Di Tullio added that he would like to know more about the interaction between diastolic dysfunction, MRI abnormalities, and cognitive impairment risk. “In this study, MRI abnormalities and cognitive impairment are treated as separate outcomes, with diastolic dysfunction being the exposure for each of them. An additional analysis of the association between diastolic dysfunction and cognitive impairment stratified by presence or absence of brain MRI findings would have been interesting.”

Dr. Parker responded that this is an area of investigation. “We suspect that our cognitive findings would not be explained by any one MRI measure, though a comprehensive examination of MRI findings would be of benefit. The thought that there may be a reversible cardiac abnormality that does not have a structural brain imaging correlate on MRI is an interesting possibility,” she said.

Dr. Di Tullio also pointed out that at present, there is no specific treatment for diastolic dysfunction other than to address some the conditions that predispose to it, such as hypertension and atrial fibrillation.

“We completely agree that specific treatments are an area of investigation and that treatment is therefore targeted at associated modifiable conditions,” Dr. Parker replied.

Treatment with a PCSK9 inhibitor, as well as achieving dramatically lowered cholesterol levels, did not mess with patients’ minds. Results from a cognition self-assessment completed by more than 22,000 patients when they finished participation in the FOURIER pivotal outcomes trial for evolocumab showed no signal of mental harm from either treatment with this PCSK9 inhibitor or from reaching a serum level of low-density lipoprotein cholesterol (LDL-C) of less than 20 mg/dL.

“We observed that patients treated with evolocumab, as well as those who achieved progressively very low LDL-C at 4 weeks in the FOURIER trial, had similar self-reported cognition in comparison with those receiving placebo and those with higher achieved LDL-C levels,” wrote a team of researchers from the trial in an article published online on May 4 (J Am Coll Cardiol. 2020 May 12;75[18]: 2283-93). “These data confirm the neurocognitive safety of intensive LDL-C reduction with evolocumab while reducing recurrent CV [cardiovascular] events in high-risk patients, and suggest that very low achieved LDL-C levels may be safely targeted for high-risk patients.”

The findings added to prior results documenting the cognitive safety of evolocumab (Repatha) from a much smaller FOURIER substudy that involved more intensive testing, the EBBINGHAUS (Evaluating PCSK9 Binding Antibody Influence on Cognitive Health in High Cardiovascular Risk Subjects) study with 1,204 patients drawn from the broader study and tested after a median 19 months on treatment (N Engl J Med. 2017 Aug 17;377[17]: 633-43), as well as reports of neurocognitive safety for the other U.S. approved PCSK9 (proprotein convertase subtilisin kexin 9) inhibitor, alirocumab (Praluent) (N Engl J Med. 2015 Apr 16;372[16]:1489-99), various statins (J Gen Intern Med. 2015 Mar;30[3]: 348-58), and a third type of LDL-C–lowering agent, ezetimibe (JAMA Cardiol. 2017 May;2[5]:547-55).

Despite this evidence from across several drug classes that all cut LDL-C a long-standing but unsubstantiated belief persists among some that lipid lowering, especially by statins, blunts mental function, misinformation that’s easy to find on the Internet. “I estimate that about 20% of patients prescribed a statin won’t take it because of something they’ve heard” including that statins make you stupid. “It’s hard to undo that,” said Robert P. Giugliano, MD, a cardiologist at Brigham and Women’s Hospital in Boston and senior author for the new FOURIER study as well as for EBBINGHAUS. The same stigma has not gained nearly as much traction for PCSK9 inhibitors, however, and Dr. Giugliano said he has also recently sensed what may be a downtrend in statin apprehension.

“The information added by this study is very important,” commented Massimo R. Mannarino, MD, an atherosclerotic disease researcher at the University of Perugia (Italy). “The prejudice and misinformation regarding possible side effects of statins among patients and also some physicians unfortunately remains very strong today,” he said in an interview. “My impression is that PCSK9 inhibitors are less affected by this negative bias and are seen as a safer alternative to statins.” Concerns about PCSK9 inhibitors have especially focused on “the possible risks from very low cholesterol levels on the brain.” The evidence from both studies and clinical experience “allows for a very positive opinion about the efficacy and safety of PCSK9 inhibitors, although the long-term effects still require a few more years of observation,” said Dr. Mannarino, who led a review of the evidence that clears this class from links to neurocognitive loss (J Clin Lipid. 2018 Sep 1;12[5]:1123-32).

FOURIER (Further Cardiovascular Outcomes Research With PCSK9 Inhibition in Subjects With Elevated Risk) randomized 27,564 patients with atherosclerotic cardiovascular disease and elevated LDL cholesterol despite maximally tolerated standard treatment. Treatment with evolocumab for a median of 2.2 years resulted in a statistically significant 15% reduction in the study’s primary efficacy endpoint, compared with placebo (N Engl J Med. 2017 May 4;376[18]:1713-22), and led to the drug receiving an indication for lowering rates of MI, stroke, and symptom-driven coronary revascularization.

The prespecified substudy reported by Dr. Giugliano and his associates focused on a 23-question, validated, self-assessment survey of cognitive function completed by 22,655 of the FOURIER patients (82%). The more than 4,900 other patients in the study who did not complete the survey had modestly higher prevalence rates of various comorbidities at baseline, and also higher rates of adverse outcomes during follow-up, and in many cases these adverse outcome may have contributed to these patients not being able to complete their end-of-study cognitive assessment. For example, almost a quarter of the patients who did not complete their end-of-study cognitive assessment failed to do so because they had already died.

Overall, the prevalence of patients indicating a cognitive decline was virtually identical among 11,363 patients who had been maintained on evolocumab, with a 3.7% rate, and the 11,292 patients in the placebo group, with a 3.6% rate. When analyzed by achieved level of LDL-C after 4 weeks on treatment, the 2,338 patients with a level below 20 mg/dL had a 3.8% rate of self-reported cognitive loss, compared with a 4.5% rate among 3,613 patients who had an LDL-C level of at least 100 mg/dL when measured 4 weeks into the study.

One of the strengths of the new cognitive analysis is that, although it did not use the more sophisticated assessment tests employed on fewer patients in the EBBINGHAUS substudy, it used the Everyday Cognition scale (Neuropsychiatry. 2008 Jul;22[4]: 531-44). “We asked patients what they have experienced, and in the end that is what’s important, so this adds to the neurocognitive testing,” run in EBBINGHAUS, Dr. Giugliano said in an interview.

“The neurocognitive results in the present study were self-reported, and that might be a limitation, as it is less specific and objective, but it is also a strength, as it could be more sensitive” especially for a “nocebo effect common to all lipid-lowering drugs linked to the bad reputation historically attributed to statins,” Dr. Mannarino said.

Should the new FOURIER data “be interpreted as definitive evidence that intensive LDL-C lowering with PCSK9 monoclonal antibodies has no major harmful cognitive effects, at least over a period of 3 years? The answer appears to be a qualified yes, but with three important caveats,” Jennifer G. Robinson, MD, a professor of epidemiology at the University of Iowa College of Public Health in Iowa City, said in an editorial that accompanied the new report (J Am Coll Cardiol. 2020 May 12;75[18]:2294-6). Her three caveats are the missing 18% of patients who never took the end-of-study assessment, the relative paucity of patients at very advanced age in FOURIER, in which patients averaged 62.5 years old, and the exclusion from FOURIER of patients with a history of hemorrhagic stroke. Dr. Robinson also cited the 2.2 year median follow-up as leaving unsettled the potential cognitive impact of longer treatment.

In response, Dr. Giugliano noted that the very large size of FOURIER and the 22,655 patients who completed their survey provided substantial numbers of patients to address some of these concerns in robust subgroup analyses. For example, the new report showed no signal of excess cognitive complaints with evolocumab treatment among 1,999 patients who were at least 75 years old when entering the study, or in more than 5,000 patients with a history of cerebrovascular disease at baseline, or in 1,990 patients with a history of a nonstroke neurologic disease. In addition, while he conceded that the 18% of patients not accounted for in the new study placed some limits on generalizability of the findings, he also maintained that this unavoidable failure to collect data from a modest percentage of patients doesn’t scuttle the overarching signal of cognitive safety for most patients. And regarding the duration of treatment monitored, he noted that 5-year follow-up cognitive assessments are planned.
