Experts Challenge New Diagnostic Criteria for Alzheimer’s disease
In a paper published online in JAMA Neurology, the International Working Group (IWG), which includes 46 experts from 17 countries, is recommending that the diagnosis of Alzheimer’s disease be limited to individuals with mild cognitive impairment or dementia and not be applied to cognitively normal individuals with Alzheimer’s disease biomarkers such as amyloid-beta 42/40 or p-tau.
Clinicians should be “very careful” about using the “A” word (Alzheimer’s) for cognitively unimpaired people with Alzheimer’s disease biomarkers, said the paper’s first author Bruno Dubois, MD, professor of neurology, Sorbonne University and Department of Neurology, Pitié-Salpêtrière Hospital, Paris, France.
Providing an Alzheimer’s disease diagnosis to those who have a high chance of never developing cognitive impairment can be psychologically harmful, said Dubois.
“It’s not something small like telling someone they have a fever. Just imagine you’re 65 years old and are amyloid positive, and you’re told you have Alzheimer’s disease. It affects the decisions you make for the rest of your life and changes your vision of your future, even though you may never develop the disease,” he added.
Divergent View
The IWG’s perspective on Alzheimer’s disease contrasts with a recent proposal from the Alzheimer’s Association. The Alzheimer’s Association criteria suggest that Alzheimer’s disease should be regarded solely as a biological entity, which could include cognitively normal individuals with one core Alzheimer’s disease biomarker.
The IWG noted that its concerns regarding the application of a purely biological definition of Alzheimer’s disease in clinical practice prompted the group to consider updating its guidelines, potentially offering “an alternative definitional view of Alzheimer’s disease as a clinical-biological construct for clinical use.”
The group conducted a PubMed search for relevant Alzheimer’s disease articles, and included references, published between July 2020 and March 2024. The research showed the majority of biomarker-positive, cognitively normal individuals will not become symptomatic during their lifetime.
The risk of a 55-year-old who is amyloid positive developing Alzheimer’s disease is not that much higher than that for an individual of a similar age who is amyloid negative, Dubois noted. “There’s an 83% chance that person will never develop Alzheimer’s disease.”
Disclosing a diagnosis of Alzheimer’s disease to cognitively normal people with only one core Alzheimer’s disease biomarker represents “the most problematic implication of a purely biological definition of the disease,” the authors noted.
“A biomarker is a marker of pathology, not a biomarker of disease,” said Dubois, adding that a person may have markers for several different brain diseases.
The IWG recommends the following nomenclature: At risk for Alzheimer’s disease for those with Alzheimer’s disease biomarkers but low lifetime risk and presymptomatic Alzheimer’s disease for those with Alzheimer’s disease biomarkers with a very high lifetime risk for progression such as individuals with autosomal dominant genetic mutations and other distinct biomarker profiles that put them at extremely high lifetime risk of developing the disease.
Dubois emphasized the difference between those showing typical Alzheimer’s disease symptoms with positive biomarkers who should be considered to have the disease and those with positive biomarkers but no typical Alzheimer’s disease symptoms who should be considered at risk.
This is an important distinction as it affects research approaches and assessment of risks, he said.
For low-risk asymptomatic individuals, the IWG does not recommend routine diagnostic testing outside of the research setting. “There’s no reason to send a 65-year-old cognitively normal subject off to collect biomarker information,” said Dubois.
He reiterated the importance of clinicians using appropriate and sensitive language surrounding Alzheimer’s disease when face to face with patients. This issue “is not purely semantic; this is real life.”
For these patients in the clinical setting, “we have to be very careful about proposing treatments that may have side effects,” he said.
However, this does not mean asymptomatic at-risk people should not be studied to determine what pharmacological interventions might prevent or delay the onset of clinical disease, he noted.
Presymptomatic individuals who are at a high risk of developing Alzheimer’s disease “should be the target for clinical trials in the future” to determine best ways to delay the conversion to Alzheimer’s disease, he said.
The main focus of such research should be to better understand the “biomarker pattern profile” that is associated with a high risk of developing Alzheimer’s disease, said Dubois.
Plea for Unity
In an accompanying editorial, Ronald C. Petersen, PhD, MD, director, Mayo Clinic Alzheimer’s Disease Research Center and Mayo Clinic Study of Aging, Rochester, Minnesota, and colleagues outline the difference between the IWG and Alzheimer’s Association positions.
As the IWG uses Alzheimer’s disease to define those with cognitive impairment and the Alzheimer’s Association group uses Alzheimer’s disease to define those with the pathology of the disease, the field is now at a crossroads. “Do we name the disease before clinical symptoms?” they asked.
They note that Alzheimer’s Association criteria distinguish between a disease and an illness, whereas the IWG does not. “As such, although the primary disagreement between the groups is semantic, the ramifications of the labeling can be significant.”
It is “incumbent” that the field “come together” on an Alzheimer’s disease definition, the editorial concluded. “Neither the Alzheimer’s Association or IWG documents are appropriate to serve as a guide for how to apply biomarkers in a clinical setting. Appropriate-use criteria are needed to form a bridge between biological frameworks and real-world clinical practice so we can all maximally help all of our patients with this disorder.”
In a comment, Reisa Sperling, MD, professor of neurology, Harvard Medical School, and director, Center for Alzheimer Research and Treatment, Brigham and Women’s Hospital and Massachusetts General Hospital, all in Boston, who is part of the Alzheimer’s Association work group that published the revised criteria for diagnosis and staging of Alzheimer’s disease, likened Alzheimer’s disease, which begins in the brain many years before dementia onset, to cardiovascular disease in that it involves multiple processes. She noted the World Health Organization classifies cardiovascular disease as a “disease” prior to clinical manifestations such as stroke and myocardial infarction.
“If someone has Alzheimer’s disease pathology in their brain, they are at risk for dementia or clinical manifestations of the disease — just like vascular disease quantifies the risk of stroke or heart attack, not risk of developing ‘vascular disease’ if the underlying vascular disease is already present,” said Sperling.
A large part of the controversy is related to terminology and the “stigma” of the “A” word in the same way there used to be fear around using the “C” word — cancer, said Sperling.
“Once people began talking about cancer publicly as a potentially treatable disease and began getting screened and diagnosed before symptoms of cancer were manifest, this has had a tremendous impact on public health.”
She clarified that her work group does not recommend screening asymptomatic people with Alzheimer’s disease biomarkers. “We actually need to prove that treating at the preclinical stage of the disease is able to prevent clinical impairment and dementia,” she said, adding “hopefully, we are getting closer to this.”
Dubois reported no relevant disclosures. Petersen reported receiving personal fees from Roche, Genentech, Eli Lilly and Company, Eisai, and Novo Nordisk outside the submitted work and royalties from Oxford University Press, UpToDate, and Medscape educational activities.

Novel Intervention Slows Cognitive Decline in At-Risk Adults
new research suggests.
The cognitive remediation intervention included a series of progressively difficult computer-based and facilitator-monitored mental exercises designed to sharpen cognitive function.
Researchers found that using cognitive remediation with tDCS slowed decline in executive function and verbal memory more than other cognitive functions. The effect was stronger among people with rMDD versus those with MCI and in those at low genetic risk for Alzheimer’s disease.
“We have developed a novel intervention, combining two interventions that if used separately have a weak effect but together have substantial and clinically meaningful effect of slowing the progression of cognitive decline,” said study author Benoit H. Mulsant, MD, chair of the Department of Psychiatry, University of Toronto, Ontario, Canada, and senior scientist at the Center for Addiction and Mental Health, also in Toronto.
The findings were published online in JAMA Psychiatry.
High-Risk Group
Research shows that older adults with MDD or MCI are at high risk for cognitive decline and dementia. Evidence also suggests that depression in early or mid-life significantly increases the risk for dementia in late life, even if the depression has been in remission for decades.
A potential mechanism underlying this increased risk for dementia could be impaired cortical plasticity, or the ability of the brain to compensate for damage.
The PACt-MD trial included 375 older adults with rMDD, MCI, or both (mean age, 72 years; 62% women) at five academic hospitals in Toronto.
Participants received either cognitive remediation plus tDCS or sham intervention 5 days per week for 8 weeks (acute phase), followed by 5-day “boosters” every 6 months.
tDCS was administered by trained personnel and involved active stimulation for 30 minutes at the beginning of each cognitive remediation group session. The intervention targets the prefrontal cortex, a critical region for cognitive compensation in normal cognitive aging.
The sham group received a weakened version of cognitive remediation, with exercises that did not get progressively more difficult. For the sham stimulation, the current flowed at full intensity for only 54 seconds before and after 30-second ramp-up and ramp-down phases, to create a blinding effect, the authors noted.
A geriatric psychiatrist followed all participants throughout the study, conducting assessments at baseline, month 2, and yearly for 3-7 years (mean follow-up, 48.3 months).
Participants’ depressive symptoms were evaluated at baseline and at all follow-ups and underwent neuropsychological testing to assess six cognitive domains: processing speed, working memory, executive functioning, verbal memory, visual memory, and language.
To get a norm for the cognitive tests, researchers recruited a comparator group of 75 subjects similar in age, gender, and years of education, with no neuropsychiatric disorder or cognitive impairment. They completed the same assessments but not the intervention.
Study participants and assessors were blinded to treatment assignment.
Slower Cognitive Decline
Participants in the intervention group had a significantly slower decline in cognitive function, compared with those in the sham group (adjusted z score difference [active – sham] at month 60, 0.21; P = .006). This is equivalent to slowing cognitive decline by about 4 years, researchers reported. The intervention also showed a positive effect on executive function and verbal memory.
“If I can push dementia from 85 to 89 years and you die at 86, in practice, I have prevented you from ever developing dementia,” Mulsant said.
The efficacy of cognitive remediation plus tDCS in rMDD could be tied to enhanced neuroplasticity, said Mulsant.
The treatment worked well in people with a history of depression, regardless of MCI status, but was not as effective for people with just MCI, researchers noted. The intervention also did not work as well among people at genetic risk for Alzheimer’s disease.
“We don’t believe we have discovered an intervention to prevent dementia in people who are at high risk for Alzheimer disease, but we have discovered an intervention that could prevent dementia in people who have an history of depression,” said Mulsant.
These results suggest the pathways to dementia among people with MCI and rMDD are different, he added.
Because previous research showed either treatment alone demonstrated little efficacy, researchers said the new results indicate that there may be a synergistic effect of combining the two.
The ideal amount of treatment and optimal age for initiation still need to be determined, said Mulsant. The study did not include a comparator group without rMDD or MCI, so the observed cognitive benefits might be specific to people with these high-risk conditions. Another study limitation is lack of diversity in terms of ethnicity, race, and education.
Promising, Important Findings
Commenting on the research, Badr Ratnakaran, MD, assistant professor and division director of geriatric psychiatry at Carilion Clinic–Virginia Tech Carilion School of Medicine, Roanoke, said the results are promising and important because there are so few treatment options for the increasing number of older patients with depression and dementia.
The side-effect profile of the combined treatment is better than that of many pharmacologic treatments, Ratnakaran noted. As more research like this comes out, Ratnakaran predicts that cognitive remediation and tCDS will become more readily available.
“This is telling us that the field of psychiatry, and also dementia, is progressing beyond your usual pharmacotherapy treatments,” said Ratnakaran, who also is chair of the American Psychiatric Association’s Council on Geriatric Psychiatry.
The study received support from the Canada Brain Research Fund of Brain Canada, Health Canada, the Chagnon Family, and the Centre for Addiction and Mental Health Discovery Fund. Mulsant reported holding and receiving support from the Labatt Family Chair in Biology of Depression in Late-Life Adults at the University of Toronto; being a member of the Center for Addiction and Mental Health Board of Trustees; research support from Brain Canada, Canadian Institutes of Health Research, Center for Addiction and Mental Health Foundation, Patient-Centered Outcomes Research Institute, and National Institutes of Health; and nonfinancial support from Capital Solution Design and HappyNeuron. Ratnakaran reported no relevant conflicts.

To get a norm for the cognitive tests, researchers recruited a comparator group of 75 subjects similar in age, gender, and years of education, with no neuropsychiatric disorder or cognitive impairment. They completed the same assessments but not the intervention.
Study participants and assessors were blinded to treatment assignment.
Slower Cognitive Decline
Participants in the intervention group had a significantly slower decline in cognitive function, compared with those in the sham group (adjusted z score difference [active – sham] at month 60, 0.21; P = .006). This is equivalent to slowing cognitive decline by about 4 years, researchers reported. The intervention also showed a positive effect on executive function and verbal memory.
“If I can push dementia from 85 to 89 years and you die at 86, in practice, I have prevented you from ever developing dementia,” Mulsant said.
The efficacy of cognitive remediation plus tDCS in rMDD could be tied to enhanced neuroplasticity, said Mulsant.
The treatment worked well in people with a history of depression, regardless of MCI status, but was not as effective for people with just MCI, researchers noted. The intervention also did not work as well among people at genetic risk for Alzheimer’s disease.
“We don’t believe we have discovered an intervention to prevent dementia in people who are at high risk for Alzheimer disease, but we have discovered an intervention that could prevent dementia in people who have an history of depression,” said Mulsant.
These results suggest the pathways to dementia among people with MCI and rMDD are different, he added.
Because previous research showed either treatment alone demonstrated little efficacy, researchers said the new results indicate that there may be a synergistic effect of combining the two.
The ideal amount of treatment and optimal age for initiation still need to be determined, said Mulsant. The study did not include a comparator group without rMDD or MCI, so the observed cognitive benefits might be specific to people with these high-risk conditions. Another study limitation is lack of diversity in terms of ethnicity, race, and education.
Promising, Important Findings
Commenting on the research, Badr Ratnakaran, MD, assistant professor and division director of geriatric psychiatry at Carilion Clinic–Virginia Tech Carilion School of Medicine, Roanoke, said the results are promising and important because there are so few treatment options for the increasing number of older patients with depression and dementia.
The side-effect profile of the combined treatment is better than that of many pharmacologic treatments, Ratnakaran noted. As more research like this comes out, Ratnakaran predicts that cognitive remediation and tCDS will become more readily available.
“This is telling us that the field of psychiatry, and also dementia, is progressing beyond your usual pharmacotherapy treatments,” said Ratnakaran, who also is chair of the American Psychiatric Association’s Council on Geriatric Psychiatry.
The study received support from the Canada Brain Research Fund of Brain Canada, Health Canada, the Chagnon Family, and the Centre for Addiction and Mental Health Discovery Fund. Mulsant reported holding and receiving support from the Labatt Family Chair in Biology of Depression in Late-Life Adults at the University of Toronto; being a member of the Center for Addiction and Mental Health Board of Trustees; research support from Brain Canada, Canadian Institutes of Health Research, Center for Addiction and Mental Health Foundation, Patient-Centered Outcomes Research Institute, and National Institutes of Health; and nonfinancial support from Capital Solution Design and HappyNeuron. Ratnakaran reported no relevant conflicts.

AHA Scientific Statement Links Three Common Cardiovascular Diseases to Cognitive Decline, Dementia
The statement includes an extensive research review and offers compelling evidence of the inextricable link between heart health and brain health, which investigators said underscores the benefit of early intervention.
The cumulative evidence “confirms that the trajectories of cardiac health and brain health are inextricably intertwined through modifiable and nonmodifiable factors,” the authors wrote.
Investigators say the findings reinforce the message that addressing cardiovascular health early in life may deter the onset or progression of cognitive impairment later on.
And the earlier this is done, the better, said lead author Fernando D. Testai, MD, PhD, a professor of neurology and the vascular neurology section head, Department of Neurology and Rehabilitation, University of Illinois, Chicago.
The statement was published online in Stroke.
Bridging the Research Gap
It’s well known that there’s a bidirectional relationship between heart and brain function. For example, heart failure can lead to decreased blood flow that can damage the brain, and stroke in some areas of the brain can affect the heart.
However, that’s only part of the puzzle and doesn’t address all the gaps in the understanding of how cardiovascular disease contributes to cognition, said Testai.
“What we’re trying to do here is to go one step further and describe other connections between the heart and the brain,” he said.
Investigators carried out an extensive PubMed search for heart failure, atrial fibrillation, and coronary heart disease. Researchers detailed the frequency of each condition, mechanisms by which they might cause cognitive impairment, and prospects for prevention and treatment to maintain brain health.
A recurring theme in the paper is the role of inflammation. Evidence shows there are “remarkable similarities in the inflammatory response that takes place,” with both cardiac disease and cognitive decline, said Testai.
Another potential shared mechanism relates to biomarkers, particularly amyloid, which is strongly linked to Alzheimer’s disease.
“But some studies show amyloid can also be present in the heart, especially in patients who have decreased ejection fraction,” said Testai.
Robust Heart-Brain Connection
The statement’s authors collected a substantial amount of evidence showing vascular risk factors such as hypertension and diabetes “can change how the brain processes and clears up amyloid,” Testai added.
The paper also provides a compilation of evidence of shared genetic predispositions when it comes to heart and brain disorders.
“We noticed that some genetic signatures that have historically been associated with heart disease seem to also correlate with structural changes in the brain. That means that at the end of the day, some patients may be born with a genetic predisposition to developing both conditions,” said Testai.
This indicates that the link between the two organs “begins as early as conception” and underscores the importance of adopting healthy lifestyle habits as early as possible, he added.
“That means you can avoid bad habits that eventually lead to hypertension, diabetes, and cholesterol, that eventually will lead to cardiac disease, which eventually will lead to stroke, which eventually will lead to cognitive decline,” Testai noted.
However, cardiovascular health is more complicated than having good genes and adhering to a healthy lifestyle. It’s not clear, for example, why some people who should be predisposed to developing heart disease do not develop it, something Testai refers to as enhanced “resilience.”
For example, Hispanic or Latino patients, who have relatively poor cardiovascular risk factor profiles, seem to be less susceptible to developing cardiac disease.
More Research Needed
While genetics may partly explain the paradox, Testai believes other protective factors are at play, including strong social support networks.
Testai referred to the AHA’s “Life’s Essential 8” — the eight components of cardiovascular health. These include a healthy diet, participation in physical activity, nicotine avoidance, healthy sleep, healthy weight, and healthy levels of blood lipids, blood glucose, and blood pressure.
More evidence is needed to show that effective management of cardiac disease positively affects cognition. Currently, cognitive measures are rarely included in studies examining various heart disease treatments, said Testai.
“There should probably be an effort to include brain health outcomes in some of the cardiac literature to make sure we can also measure whether the intervention in the heart leads to an advantage for the brain,” he said.
More research is also needed to determine whether immunomodulation has a beneficial effect on the cognitive trajectory, the statement’s authors noted.
They point out that the interpretation and generalizability of the studies described in the statement are confounded by disparate methodologies, including small sample sizes, cross-sectional designs, and underrepresentation of Black and Hispanic individuals.
‘An Important Step’
Reached for a comment, Natalia S. Rost, MD, Chief of the Stroke Division at Massachusetts General Hospital and professor of neurology at Harvard Medical School, both in Boston, said this paper “is an important step” in terms of pulling together pertinent information on the topic of heart-brain health.
She praised the authors for gathering evidence on risk factors related to atrial fibrillation, heart failure, and coronary heart disease, which is “the part of the puzzle that is controllable.”
This helps reinforce the message that controlling vascular risk factors helps with brain health, said Rost.
But brain health is “much more complex than just vascular health,” she said. It includes other elements such as freedom from epilepsy, migraine, traumatic brain injury, and adult learning disabilities.
No relevant conflicts of interest were disclosed.

McDonald Criteria Update Aims to Simplify, Speed MS Diagnosis
COPENHAGEN —
Among its recommendations, the expert panel advises incorporating optic nerve imaging for diagnosis and applying stricter criteria for older patients. In addition, it proposes that radiologically isolated syndrome (RIS) may be diagnosed as MS in certain cases and that disease dissemination in time (DIT) should no longer be required.
The proposed criteria changes were presented at the 2024 ECTRIMS annual meeting.
Committee member Xavier Montalban, MD, PhD, from the Department of Neurology and the MS Centre of Catalonia at Vall d’Hebron University Hospital in Barcelona, Spain, told conference attendees that MS is a diagnosis of exclusion.
Brain and spinal cord MRI remains the most useful paraclinical test to diagnose the disease, he said, and an abnormal MRI showing typical lesions is required.
Dr. Montalban noted that optic neuritis is the first manifestation of MS in 25%-35% of cases with clinically isolated syndrome (CIS) — one of the four MS disease courses.
Therefore, he said, the panel is recommending that the optic nerve serve as the “fifth topography” or a fifth anatomical location to demonstrate dissemination in space (DIS) if there’s no better explanation for optic nerve pathology, he said.
Considerable evidence supports the minimal threshold of at least one lesion in at least two of the five topographies after including the optic nerve, he added.
DIS Alone Sufficient?
The panel also concluded that demonstrating DIS alone, without the need for DIT or positive cerebrospinal fluid (CSF), may be sufficient for an MS diagnosis. Currently, both DIS and DIT are required.
The committee broached the topic of RIS, which is identified by the incidental discovery of central nervous system (CNS) white matter T2-weighted hyperintense foci on MRI. These hyperintense foci demonstrate morphological and spatial characteristics highly typical of MS but without clinical symptomatology related to inflammatory demyelination.
Dr. Montalban noted that most patients with RIS will develop MS within 10 years. For these individuals, the panel concluded that the following criteria are sufficient for an MS diagnosis: fulfilling both DIS and DIT; fulfilling DIS and the presence of oligoclonal bands (OCBs) in the cerebrospinal fluid; or fulfilling DIS along with six or more central vein signs (CVS).
The panel proposes the addition of CVS and paramagnetic rim lesions, which are MRI markers of chronic active lesions, as optional tools for MS diagnosis in certain situations. Demonstration of CVS by MRI can increase specificity, said Dr. Montalban.
Evidence also suggests that kappa free light chains (KFLCs) could serve as a valid, simpler, and rater-independent alternative to detecting OCBs, he added. Because KFLCs are interchangeable with OCBs, they can be used in place of OCBs for diagnosing MS through CSF analysis.
Stricter Criteria
The panel is also calling for stricter criteria for confirming an MS diagnosis in those over age 50 or individuals with headache or vascular disorders. In such patients, they strongly recommend additional features such as a spinal cord lesion, positive CSF, and CVS select 6 (six positive lesions).
The panel is also recommending laboratory tests (MOG-IgG Ab) to confirm a diagnosis in children and adolescents. Dr. Montalban noted the presence of CVS in about 50% of T2 lesions strongly suggests MS in this population.
Primary progressive MS (PPMS) requires evidence of clinical progression over at least 12 months. The committee determined that the same criteria for relapsing-remitting MS could be used for PPMS.
Having a single, unified framework of diagnostic criteria will be “very useful,” said Dr. Montalban.
During the same meeting session, Marcello Moccia, MD, PhD, University College London (UCL) Queen Square Institute of Neurology, Faculty of Brain Sciences, London, England, presented examples of patients for whom the revised criteria could be beneficial.
These examples help illustrate how using the new criteria, for example optic nerve imaging, could lead to earlier diagnoses, and, in some cases, easier diagnoses, possibly with less CSF, he said. It could also lead to fewer misdiagnoses, he added, thanks to high-specificity tools.
Implementing the new criteria could offer greater flexibility and reduce complexity, Dr. Moccia concluded, adding that not every patient with suspected MS requires exhaustive testing.
The committee’s next steps will include consulting with the wider MS community and preparing the information for publication, said Dr. Montalban.
Commenting on the proposals, Bruce Bebo, executive vice president of research, National MS Society, agreed the proposed changes to the McDonald Criteria will make diagnosing MS “faster and easier.”
“Importantly, we are providing guidance that is inclusive — how to confirm diagnoses in children, or in people over the age of 50,” said Dr. Bebo. “We’re bringing the latest research and imaging technology to the forefront, to help people with MS get treatment faster, so they can live their best lives.”

Genetically Driven Depression Tied to Increased MS Disease Activity
COPENHAGEN — , early results of a new study showed.
Unlike the previous research, the current analysis used polygenic risk scores for depression, which summarize the estimated effect of genetic variants to determine the potential association with MS disease activity, so results are less likely to be explained by reverse causality.
This study increases awareness of the link between depression and MS, said study investigator Kaarina Kowalec, PhD, assistant professor, College of Pharmacy, Rady Faculty of Health Sciences, University of Manitoba, Winnipeg, Manitoba, Canada. “We’re starting to understand how depression affects relapses and disability progression in MS,” she said.
The findings were presented at the 2024 ECTRIMS annual meeting.
Common Comorbidity
Depression is a common comorbidity in patients with MS and is associated with increased relapse and disability progression. Depression risk is partly polygenic in nature, involving numerous common genetic variants, said Dr. Kowalec.
The case-control study included 3420 relapsing-onset MS cases of European ancestry from four existing cohorts in three countries.
The Canadian cohort included those enrolled in a prospective longitudinal study of psychiatric comorbidity in chronic immune-mediated inflammatory disease (IMID), including MS; the Swedish cohort was an MS registry (SSReg) that encompasses 64 MS clinics (the cohort was split into two groups); and the US cohort was enrolled in a clinical trial of combined therapy with interferon and glatiramer acetate (CombiRx) in patients with MS.
The median follow-up in these cohorts ranged from 3 to 5 years.
Not surprisingly, most participants were women (from 71% in one of the Swedish cohorts to 83% in the Canadian cohort), and the age at MS onset ranged from 29 years in the Canadian cohort to 35 years in one of the Swedish cohorts.
The median baseline Expanded Disability Status Scale (EDSS) score was higher in the Canadian cohort (3.5) than in the Swedish (1.5) and US (2.0) cohorts, “reflective of the Canadian cohort being slightly more progressed,” said Dr. Kowalec.
Inherited Variants
To measure depression heritability, researchers generated a polygenic risk score in whole-genome imputed genotypes. The score reflects the number of inherited common genetic variants, weighted by effect sizes.
Researchers investigated the association between depression polygenic risk scores (top 20% vs. bottom 80%) with annualized relapse rate and worsening disability in MS measured by the rate of change in EDSS score. In the US cohort, they also explored the association between depression polygenic risk scores and time to relapse and confirmed EDSS worsening.
Covariates included use of disease-modifying therapy, age, sex, and the first five genetic ancestry principal components. The latter was done to capture residual stratification by genetic ancestry, although Dr. Kowalec stressed analyses were done only in those of European ancestry.
Investigators found a higher depression polygenic risk score was associated with relapse risk (incident rate ratio, 1.23; 95% CI, 1.01-1.49).
“Essentially, for every one standard deviation increase in the depression polygenic score, we found a significant increased hazard of 23% for experiencing a relapse over the follow-up period,” said Dr. Kowalec, who is also affiliated with the Department of Medical Epidemiology and Biostatistics, Karolinska Institutet, Stockholm, Sweden.
She noted the Canadian cohort did not have many relapses, while the US and Swedish cohorts “had an increased rate.”
Other analyses examined the risk of having a relapse or worsening disability. Every one SD increase in the depression polygenic risk score was significantly associated with a 2.2 greater risk of experiencing relapse (hazard ratio [HR], 2.20; 95% CI, 1.35-3.60) and a 51% increased risk for confirmed EDSS progression (HR, 1.51; 95% CI, 1.03-2.22).
‘An Ideal Marker’
Use of polygenetic risk scores reduces the possibility of reverse causation, noted Dr. Kowalec. “These markers are fixed at birth and don’t change over your lifespan, so they’re really an ideal marker.”
The results suggest polygenetic risk scores represent a potential biomarker for risk stratification in people with MS, said Dr. Kowalec. Although depression polygenic risk scores are not currently available in clinical practice, “I would hope this would change in the next 3-4 years,” she said.
Asked by a delegate if confounding by a third variable is possible, Dr. Kowalec said because genetic markers don’t change over time, there is a hint that the direction is causal and that depression is driving the outcome. However, she added, further confirmation is needed.
Dr. Kowalec noted that there were no data on antidepressant use but noted that about half of the Canadian and US cohorts — and likely the same number in the Swedish cohorts — self-reported depression.
A limitation of the study was that it included only participants of European ancestry.
Clinical Implications Unclear
Commenting on the research, Lauren Gluck, MD, program director, Montefiore Multiple Sclerosis Center, Bronx, New York, described the study as “fascinating” but noted that it’s unclear how to use this new information in clinical practice.
“Clinicians frequently ask people with MS about mood symptoms and offer interventions like antidepressants and referrals to therapists. However, genetic testing is not routine, so we don’t yet know who to target based on these data.”
Preexisting depression or more severe depression could be viewed as a “red flag” for risk for more disease activity in the future, she said.
“This could encourage clinicians to use more highly effective therapy in these patients, similar to our strategies for people with MS with frequent attacks and more disease burden on MRIs.”
The study received support from the Consortium of Multiple Sclerosis Centers and the Congressionally Directed Medical Research Programs, Department of Defense.
Dr. Kowalec reported no relevant conflicts of interest.

High-Dose Vitamin D Linked to Lower Disease Activity in CIS
COPENHAGEN — , results of a randomized, controlled trial suggest. In addition, cholecalciferol had a favorable safety profile and was well tolerated.
“These data support high-dose vitamin D supplementation in early MS and make vitamin D the best candidate for add-on therapy evaluation in the therapeutic strategy for multiple sclerosis [MS],” said study author Eric Thouvenot, MD, PhD, University Hospital of Nimes, Neurology Department, Nimes, France.
The study was presented at the 2024 ECTRIMS annual meeting.
Vitamin D Supplementation Versus Placebo
Research shows vitamin D deficiency is a risk factor for MS. However, results of previous research investigating vitamin D supplementation in MS, with different regimens and durations, have been contradictory.
The current double-blind study included 303 adults newly diagnosed with CIS (within 90 days) and a serum 25-hydroxy vitamin D concentration of less than 100 nmol/L at baseline. Participants had a median age of 34 years, and 70% were women.
About one third of participants had optic neuritis, two thirds had oligoclonal bands from cerebrospinal fluid analysis, and the median Expanded Disability Status Scale (EDSS) score was 1.0. Of the total, 89% fulfilled 2017 McDonald criteria for the diagnosis of relapsing-remitting MS (RRMS).
Participants were randomly assigned to receive high-dose (100,000 international units) oral cholecalciferol or placebo every 2 weeks for 24 months. Participants had a clinical visit at 3, 6, 12, 18, and 24 months, and brain and spinal cord MRI with and without gadolinium at 3, 12, and 24 months.
The primary outcome was occurrence of disease activity — relapse, new or enlarging T2 lesions, and presence of contrast-enhancing lesions.
Significant Difference
During follow-up, 60.3% in the vitamin group showed evidence of disease activity versus 74.1% in the placebo group (hazard ratio [HR], 0.66; 95% CI, 0.50-0.87; P = .004). In addition, the median time to evidence of disease activity was 432 days in the vitamin D group versus 224 days in the placebo group (P = .003).
“As you can see, the difference is really, really significant,” said Dr. Thouvenot, referring to a Kaplan-Meier curve. He said he was somewhat surprised by the “very rapid” effect of vitamin D.
He noted that the 34% reduction in relative risk for disease activity is “similar to that of some published platform therapies for CIS patients.”
An analysis of the 247 patients who met 2017 McDonald criteria for RRMS at baseline showed the same results.
Secondary analyses showed no significant reduction in relapses and no significant differences for annual change in EDSS, quality of life, fatigue, anxiety, or depression.
Additional analyses showed the HR was unchanged after adjusting for known prognostic factors including age, sex, number of lesions (< 9 vs ≥ 9), EDSS score at baseline, and delay between CIS and treatment onset.
Results showed vitamin D3 supplementation was safe and well tolerated. Dr. Thouvenot noted that 95% of participants completed the trial, and none of the 33 severe adverse events in 30 patients suggested hypercalcemia or were related to the study drug.
These encouraging new data support further studies of high-dose vitamin D supplementation as an add-on therapy in early MS, said Dr. Thouvenot. He noted that animal models suggest vitamin D added to interferon beta has a synergistic effect on the immune system.
‘Fabulous’ Research
During a question-and-answer session, delegates praised the study, with some describing it as “fantastic” or “fabulous.”
Addressing a query about why this study succeeded in showing the benefits of vitamin D while numerous previous studies did not, Dr. Thouvenot said it may be due to the longer duration or a design that was better powered to show differences.
Asked if researchers examined vitamin D blood levels during the study, Dr. Thouvenot said these measures are “ongoing.”
Responding to a question of whether high-dose vitamin D could be a lifelong treatment, he referred again to the “excellent” safety of the intervention. Not only is it well tolerated, but vitamin D benefits bones and the risk for hypercalcemia is low except perhaps for patients with tuberculosis or sarcoidosis, he said.
“When you exclude those patients, the safety is huge, so I don’t know why we should stop it once it’s started.”
This study was funded in part by the French Ministry of Health. Dr. Thouvenot reported no relevant disclosures.

Triptans Trump Newer, More Expensive Meds for Acute Migraine
new research suggested.
Results of a large systematic review and meta-analysis showed that eletriptan, rizatriptan, sumatriptan, and zolmitriptan were more effective than lasmiditan, rimegepant, and ubrogepant, which investigators found were as effective as nonsteroidal anti-inflammatory drugs (NSAIDs).
International guidelines generally endorse NSAIDs as the first-line treatment for migraine and recommend triptans for moderate to severe episodes or when the response to NSAIDs is insufficient.
However, based on the study’s findings, these four triptans should be considered the treatment of choice for migraine, study investigator Andrea Cipriani, MD, PhD, professor of psychiatry at the University of Oxford in England and director of the Oxford Health Clinical Research Facility, told a press briefing.
The investigators added that these particular triptans should be “included in the WHO [World Health Organization] List of Essential Medicines to promote global accessibility and uniform standards of care.”
The study was published online in The BMJ.
Filling the Knowledge Gap
To date, almost all migraine studies have compared migraine drugs with placebo, so there’s a knowledge gap, said Dr. Cipriani. As a result, “there’s no clear consensus among experts and guidelines about which specific drug classes should be prescribed initially, and this is a clinical problem.”
The researchers pointed out that, in recent years, lasmiditan and gepants have been introduced as further treatment options, especially for patients in whom triptans are contraindicated because of their potential vasoconstrictive effects and higher risk for ischemic events.
The analysis included 137 double-blind, randomized, controlled trials that were primarily sponsored by the pharmaceutical industry. It included 89,445 adult outpatients with migraine (mean age, 40.3 years; 85.6% women).
Only drugs licensed for migraine or headache that are recommended in at least one country were included. Researchers divided these 17 drugs into five categories: Antipyretics (paracetamol), ditans (lasmiditan), gepants (rimegepant and ubrogepant), NSAIDs (acetylsalicylic acid, celecoxib, diclofenac potassium, ibuprofen, naproxen sodium, and phenazone), and triptans (almotriptan, eletriptan, frovatriptan, naratriptan, rizatriptan, sumatriptan, and zolmitriptan).
The study’s primary outcomes were freedom from pain at 2 hours and at 2-24 hours, without the use of rescue drugs.
Investigators used sumatriptan as the reference intervention because it is the most commonly prescribed migraine drug and is included in the WHO Model Lists of Essential Medicines.
The study showed all active interventions were better than placebo for pain freedom at 2 hours; with the exception of paracetamol and naratriptan, all were better for sustained pain freedom from 2 to 24 hours.
When the active interventions were compared with each other, eletriptan outperformed other drugs for achieving pain freedom at 2 hours. It was followed by rizatriptan, sumatriptan, and zolmitriptan (odds ratio [OR], 1.35-3.01). For sustained pain freedom up to 24 hours, the most efficacious interventions were eletriptan (OR, 1.41-2.73) and ibuprofen (OR, 3.16-4.82).
As for secondary efficacy outcomes, in head-to-head comparisons, eletriptan was superior to nearly all other active interventions for pain relief at 2 hours and for the use of rescue drugs.
As for adverse events, dizziness was more commonly associated with lasmiditan, eletriptan, sumatriptan, and zolmitriptan, while fatigue and sedation occurred more frequently with eletriptan and lasmiditan. Nausea was more often associated with lasmiditan, sumatriptan, zolmitriptan, and ubrogepant. Eletriptan was the only intervention most frequently associated with chest pain or discomfort.
Need to Update Guidelines?
Considering the new results, Dr. Cipriani and study coauthor Messoud Ashina, MD, PhD, professor of neurology, University of Copenhagen in Denmark, said clinical guidelines for acute migraine management should be updated.
While triptans are contraindicated in patients with vascular disease, the researchers noted that “cerebrovascular events may present primarily as migraine-like headaches, and misdiagnosis of transient ischemic attack and minor stroke as migraine is not rare.”
Recently, lasmiditan, rimegepant, and ubrogepant — which are not associated with vasoconstrictive effects — have been promoted as alternatives in patients for whom triptans are contraindicated or not tolerated. But the high costs of these drugs put them out of reach for some patients, the investigators noted.
Triptans are widely underutilized, Dr. Ashina noted during the press briefing. Current use ranges from 17% to 22% in the United States and from 3% to 22.5% in Europe.
The investigators said that triptans have been shown to be superior and should be promoted globally, adding that the limited access and substantial underutilization of these medications are “missed opportunities to offer more effective treatments.”
The new results underscore the importance of head-to-head trials, which is the gold standard, said Dr. Cipriani.
The investigators noted that the study’s main limitation was the quality of the data, which was deemed to be low, or very low, for most comparisons. Other potential limitations included lack of individual patient data; exclusion of combination drugs; inclusion of only oral treatments; and not considering type of oral formulation, consistency in response across migraine episodes, or cost-effectiveness.
The study also did not cover important clinical issues that might inform treatment decision-making, including drug overuse headache or potential withdrawal symptoms. And the authors were unable to quantify some outcomes, such as global functioning.
‘Best Profile’?
Reached for comment, Neurologist Nina Riggins, MD, PhD, Headache Center of Excellence, Palo Alto VA Medical Center in California, praised the authors for a “great job” of bringing attention to the topic.
However, she noted that the investigators’ characterization of the four triptans as having the “best profile” for acute migraine gave her pause.
“Calling triptans the medication with the ‘best profile’ might be not applicable in many cases,” she said. For example, those who need acute medication more than two to three times a week in addition to those with cardiovascular contraindications to triptans may fall outside of that category.
Dr. Riggins said that “it makes sense” that longer-acting triptans like frovatriptan and naratriptan may not rank highly for efficacy within the first 2 hours. However, these agents likely offer a superior therapeutic profile in specific contexts, such as menstrual-related migraine.
In addition, while triptans are known to cause medication overuse headache, this may not be the case with gepants, she noted.
In a release from the Science Media Center, a nonprofit organization promoting voices and views of the scientific community, Eloísa Rubio-Beltrán, PhD, research associate with The Migraine Trust at the Wolfson Sensory, Pain and Regeneration Centre, King’s College London in England, said the findings should affect migraine treatment guidelines.
“As the study highlights, due to their high efficacy and low cost, triptans should be the first-line treatment option for the acute treatment of migraine. These results should inform treatment guidelines and support the inclusion of the best performing triptans into the List of Essential Medicines, to optimize treatment, allowing patients to access more efficacious options,” said Dr. Rubio-Beltrán.
It is also important to note that gepants and ditans were developed to offer alternatives for patients who show no improvement from triptans, she added.
She pointed out that these medications were not developed as a substitute for triptans, but rather to expand the number of treatment options for migraine.
“Nonetheless,” she added, “this study highlights the need for further research on the pathophysiology of migraine, which will allow the discovery of novel targets, and thus, novel treatments options that will benefit all patient populations.”
The study was funded by the NIHR Oxford Health Biomedical Research Centre and the Lundbeck Foundation. Dr. Cipriani reported receiving research, educational, and consultancy fees from Italian Network for Pediatric Clinical Trials, Fondazione Cariplo, Lundbeck, and Angelini Pharma.

new research suggested.
Results of a large systematic review and meta-analysis showed that eletriptan, rizatriptan, sumatriptan, and zolmitriptan were more effective than lasmiditan, rimegepant, and ubrogepant, which investigators found were as effective as nonsteroidal anti-inflammatory drugs (NSAIDs).
International guidelines generally endorse NSAIDs as the first-line treatment for migraine and recommend triptans for moderate to severe episodes or when the response to NSAIDs is insufficient.
However, based on the study’s findings, these four triptans should be considered the treatment of choice for migraine, study investigator Andrea Cipriani, MD, PhD, professor of psychiatry at the University of Oxford in England and director of the Oxford Health Clinical Research Facility, told a press briefing.
The investigators added that these particular triptans should be “included in the WHO [World Health Organization] List of Essential Medicines to promote global accessibility and uniform standards of care.”
The study was published online in The BMJ.
Filling the Knowledge Gap
To date, almost all migraine studies have compared migraine drugs with placebo, so there’s a knowledge gap, said Dr. Cipriani. As a result, “there’s no clear consensus among experts and guidelines about which specific drug classes should be prescribed initially, and this is a clinical problem.”
The researchers pointed out that, in recent years, lasmiditan and gepants have been introduced as further treatment options, especially for patients in whom triptans are contraindicated because of their potential vasoconstrictive effects and higher risk for ischemic events.
The analysis included 137 double-blind, randomized, controlled trials that were primarily sponsored by the pharmaceutical industry. It included 89,445 adult outpatients with migraine (mean age, 40.3 years; 85.6% women).

Storybooks Can Help Children Deal with Skin Conditions
TORONTO —
So far, “the study demonstrates that these books have value to patients and families,” one of the study authors, Sonia Havele, MD, a pediatrician and dermatology resident at Children’s Mercy Hospital Kansas City, Kansas City, Missouri, said in an interview.
“There are tools to help kids cope with their skin conditions, but we’re underutilizing them,” she added. “And part of the reason we’re underutilizing storybooks is that we just don’t know what’s out there.” For the study, the researchers received funding to purchase 18 “creative and thoughtful” storybooks related to pediatric skin conditions, reviewed by at least two pediatric dermatologists before being selected, which are just a sample of related books that are available.
The study results were presented as a poster at the annual meeting of the Society for Pediatric Dermatology.
Children with visible skin conditions, which can include port-wine stains, capillary malformations, and congenital moles, may be subjected to teasing or bullying at school, and the conditions can also affect their quality of life.
Beauty and the Birthmark
The books include one titled “Beauty with a Birthmark” and another, “My Hair Went on Vacation.” An illustrated book, “Just Ask: Be Different, Be Brave, Be You,” by US Supreme Court Justice Sonia Sotomayor, offers tips on how to answer common questions about someone’s appearance.
Dr. Havele said that Justice Sotomayor’s book “empowers kids, their siblings, their classmates ... to ask questions, and it teaches patients not to be afraid of those questions, and to really lean into educating their peers, and their family members.”
“Kids are really just curious,” she added. “They’ll make comments like: ‘Hey, what’s that spot on your face?’ Or, they’ll ask about vitiligo because they’ve never seen somebody with it before.”
To evaluate the psychosocial impact of these types of books for children with visible skin conditions, Dr. Havele and colleagues designed a study that includes patients aged 2-12 years dealing with issues related to self-esteem, acceptance, coping, or bullying. Parents are provided with a relevant storybook to read at home with their child in a “safe and comfortable space” and “at their own pace and their own time,” said Dr. Havele.
Inside the book is a QR code to access the validated Children’s Dermatology Life Quality Index (CDLQI). Families complete the survey at baseline and provide feedback after reading the book. Researchers collect information about demographics, age, gender, and skin conditions, which included atopic dermatitis, alopecia areata, vitiligo, hemangioma, and port-wine stain.
The response rate so far is 34%, and close to 80 parents have completed the survey with their child, Dr. Havele said.
At baseline, many of the children were either moderately or severely affected in terms of their quality of life (45% scored ≥ 6 on the CDLQI).
After reading the book, about 80% of parents reported it had a positive impact, and about 20% said it had a somewhat positive impact on their child’s self-image or confidence. Almost 80% agreed, and the remainder somewhat agreed it encouraged their child to embrace differences.
Most respondents also said the book helped the parent and child cope with the child’s condition. “So really, it was overall a positive response,” said Dr. Havele. “We are able to demonstrate that these books have value in a more scientific or objective way.”
This may not be surprising. Dr. Havele referred to more formal bibliotherapy (book therapy), which has been studied in other pediatric populations, including patients with cancer and those who have experienced trauma.
Awesome Space
Pediatric dermatologists are perfectly positioned to play a role in improving the lives of their patients with skin issues. “We see the impact of visible skin disease on children all the time,” said Dr. Havele. “The dermatology visit is an awesome space and opportunity to introduce these books to families and potentially help them talk about the skin condition with their child.”
In addition to prescribing therapies, “we’re also with these kids through an emotional journey, and I think giving them tools for that emotional journey is very helpful,” she added.
Such books would have been a great help to Dr. Havele herself. Growing up, she had severe atopic dermatitis covering much of her body. “Having such a resource would have helped me better cope with my reality of being different than everyone else.”
She hopes a database will be established to house these resources so other providers can refer patients to the list of books. Other books include “The Itchy-saurus: The Dino with an itch that can’t be scratched,” “Hair in My Brush,” and “I am Unique!”
Dr. Havele had no relevant disclosures.

TORONTO —
So far, “the study demonstrates that these books have value to patients and families,” one of the study authors, Sonia Havele, MD, a pediatrician and dermatology resident at Children’s Mercy Hospital Kansas City, Kansas City, Missouri, said in an interview.
“There are tools to help kids cope with their skin conditions, but we’re underutilizing them,” she added. “And part of the reason we’re underutilizing storybooks is that we just don’t know what’s out there.” For the study, the researchers received funding to purchase 18 “creative and thoughtful” storybooks related to pediatric skin conditions, reviewed by at least two pediatric dermatologists before being selected, which are just a sample of related books that are available.
The study results were presented as a poster at the annual meeting of the Society for Pediatric Dermatology.
Children with visible skin conditions, which can include port-wine stains, capillary malformations, and congenital moles, may be subjected to teasing or bullying at school, and the conditions can also affect their quality of life.
Beauty and the Birthmark
The books include one titled “Beauty with a Birthmark” and another, “My Hair Went on Vacation.” An illustrated book, “Just Ask: Be Different, Be Brave, Be You,” by US Supreme Court Justice Sonia Sotomayor, offers tips on how to answer common questions about someone’s appearance.
Dr. Havele said that Justice Sotomayor’s book “empowers kids, their siblings, their classmates ... to ask questions, and it teaches patients not to be afraid of those questions, and to really lean into educating their peers, and their family members.”
“Kids are really just curious,” she added. “They’ll make comments like: ‘Hey, what’s that spot on your face?’ Or, they’ll ask about vitiligo because they’ve never seen somebody with it before.”
To evaluate the psychosocial impact of these types of books for children with visible skin conditions, Dr. Havele and colleagues designed a study that includes patients aged 2-12 years dealing with issues related to self-esteem, acceptance, coping, or bullying. Parents are provided with a relevant storybook to read at home with their child in a “safe and comfortable space” and “at their own pace and their own time,” said Dr. Havele.
Inside the book is a QR code to access the validated Children’s Dermatology Life Quality Index (CDLQI). Families complete the survey at baseline and provide feedback after reading the book. Researchers collect information about demographics, age, gender, and skin conditions, which included atopic dermatitis, alopecia areata, vitiligo, hemangioma, and port-wine stain.
The response rate so far is 34%, and close to 80 parents have completed the survey with their child, Dr. Havele said.
At baseline, many of the children were either moderately or severely affected in terms of their quality of life (45% scored ≥ 6 on the CDLQI).
After reading the book, about 80% of parents reported it had a positive impact, and about 20% said it had a somewhat positive impact on their child’s self-image or confidence. Almost 80% agreed, and the remainder somewhat agreed it encouraged their child to embrace differences.
Most respondents also said the book helped the parent and child cope with the child’s condition. “So really, it was overall a positive response,” said Dr. Havele. “We are able to demonstrate that these books have value in a more scientific or objective way.”
This may not be surprising. Dr. Havele referred to more formal bibliotherapy (book therapy), which has been studied in other pediatric populations, including patients with cancer and those who have experienced trauma.
Awesome Space
Pediatric dermatologists are perfectly positioned to play a role in improving the lives of their patients with skin issues. “We see the impact of visible skin disease on children all the time,” said Dr. Havele. “The dermatology visit is an awesome space and opportunity to introduce these books to families and potentially help them talk about the skin condition with their child.”
In addition to prescribing therapies, “we’re also with these kids through an emotional journey, and I think giving them tools for that emotional journey is very helpful,” she added.
Such books would have been a great help to Dr. Havele herself. Growing up, she had severe atopic dermatitis covering much of her body. “Having such a resource would have helped me better cope with my reality of being different than everyone else.”
She hopes a database will be established to house these resources so other providers can refer patients to the list of books. Other books include “The Itchy-saurus: The Dino with an itch that can’t be scratched,” “Hair in My Brush,” and “I am Unique!”

1 in 4 Unresponsive Coma Patients May Retain Some Awareness
“We found that at least 1 in 4 patients who are unresponsive to commands might actually be quite present and highly cognitive,” said study investigator Nicholas D. Schiff, MD, Feil Family Brain & Mind Research Institute and Department of Neurology, Weill Cornell Medicine, Rockefeller University Hospital, New York.
“In other words, if you go to the bedside and carefully examine someone with a severe brain injury and find no evidence of responsiveness, no one has been able to give you an a priori number to say how likely you are to be wrong in thinking this person is actually unaware, not processing language, and not capable of high-level cognitive work. And the answer to that now is at least 1 in 4 times.”
The findings were published online in The New England Journal of Medicine.
Clinical Implications?
Cognitive motor dissociation (CMD) is a condition whereby patients with a severe brain injury who are unresponsive to commands at the bedside show brain activity on functional MRI (fMRI) or electroencephalography (EEG) when presented with selective motor imagery commands, such as “imagine playing tennis,” or “ imagine opening and closing your hand.”
Previous research shows that CMD is present in 10%-20% of people with a disorder of consciousness, a rate similar to that in patients with acute or chronic brain injury.
Understanding that a patient who appears unconscious has signs of cognitive processing could change the way clinicians and family interact with such individuals. Unresponsive patients who are aware may eventually be able to harness emerging communication technologies such as brain-computer interfaces.
In addition, knowing an individual’s CMD status could aid in prognosis. “We know from one study that there’s a four times increased likelihood that patients will be independent in a year in their function if they have cognitive motor dissociation,” said Dr. Schiff.
Unlike most previous studies of CMD, which were conducted at single sites and had relatively small cohorts, this new study included 353 adults with a disorder of consciousness (mean age, 37.9 years; 64% male) at six multinational sites.
Participants were recruited using a variety of methods, including consecutive enrollment of critically ill patients in the intensive care unit and enrollment of those with chronic illness or injury who were in the postacute phase of brain injury.
Response to Commands
Study participants were at different stages of recovery from an acute brain injury that had occurred an average of 8 months before the study started.
To determine the presence or absence of an observable response to commands among participants, trained staff used the Coma Recovery Scale–Revised (CRS-R); scores on this instrument range from 0 to 23, and higher scores indicate better neurobehavioral function.
About 40% of individuals were diagnosed with coma or vegetative state, 29% with minimally conscious state–minus, and 22% with minimally conscious state–plus. In all, 10% had emerged from a minimally conscious state.
Researchers assessed response to timed and repeated commands using fMRI or EEG in participants without an observable response to verbal commands, including those with a behavioral diagnosis of coma, vegetative state, or minimally conscious state–minus, and in participants with an observable response to verbal commands.
Of the 353 study participants, 61% underwent at least one fMRI assessment and 74% at least one EEG assessment. Both fMRI and EEG were performed in 35% of participants.
Dr. Schiff explained the two assessment types provide slightly different information, in that they measuring different types of brain signals. He also noted that although “every medical center in the world” has EEG, many do not have fMRI.
The brain imaging assessments captured brain activity within the motor area of the frontal cortex when tasked with motor imagery.
Of the 241 participants deemed to be in a coma or vegetative state or minimally conscious state–minus on the basis of CRS-R score, 60 (25%) had a response to commands on task-based fMRI, task-based EEG, or both.
The percentage of participants with CMD varied across study sites, from 2% to 45%, but Dr. Schiff said the reason for this is unclear.
The proportion of participants with CMD may have been even higher if all individuals had been assessed with both imaging techniques, he said.
Higher Rate of Awareness Than in Previous Research
The investigators noted that the percentage of participants with CMD in their study was up to 10 percentage points higher than in previous studies. This may be due to the multimodal approach that classified participants undergoing assessment with both fMRI and EEG on the basis of responses on either technique, they said.
The median age was lower among participants with CMD than those without CMD (30.5 years vs 45.3 years).
Compared with participants without CMD, a higher percentage of those with such dissociation had brain trauma as an etiologic factor (65% vs 38%) and a diagnosis of minimally conscious state–minus on the CRS-R (53% vs 38%).
Among people with CMD, 18% were assessed with fMRI only, 22% with EEG only, and 60% with both fMRI and EEG.
Dr. Schiff noted that the use of both fMRI and EEG appears to be more sensitive in detecting brain activity during tasks compared with use of one of these techniques alone.
Of the 112 participants with a diagnosis of minimally conscious state–plus or who had emerged from the minimally conscious state, 38% had a response to commands on task-based fMRI, task-based EEG, or both. Among these participants, 23% were assessed with fMRI only, 19% with EEG only, and 58% with both fMRI and EEG.
Research shows “it’s very clear that people with severe brain injury continue to get better over time,” noted Dr. Schiff. “Every month and week matters, and so it probably is the case that a lot of these patients are picking up the level of recovery, and the later we go out to measure them, the more likely we are to find people who are CMD than not.”
These new results should prompt further study to explore whether detection of CMD can lead to improved outcomes, the investigators noted. “In addition, the standardization, validation, and simplification of task-based fMRI and EEG methods that are used to detect cognitive motor dissociation are needed to prompt widespread clinical integration of these techniques and investigation of the bioethical implications of the findings.”
All study participants with chronic brain injury had survived their initial illness or injury and had access to a research facility with advanced fMRI and EEG capabilities. “This survival bias may reflect greater cognitive reserve and resilience over time among the participants. As such, the results of our study may not be generalizable to the overall population of patients with cognitive motor dissociation,” the investigators wrote.
Another study limitation was that participating sites used heterogeneous strategies to acquire, analyze, and interpret data, which led to differences in the number, type, and ordering of the cognitive tasks assessed on fMRI and EEG.
“These differences, along with variations in recruitment strategies and participant characteristics, may have contributed to the unequal percentage of participants with cognitive motor dissociation observed at each site. Our findings may therefore not be generalizable across all centers,” the researchers wrote.
Only a few academic medical centers have the specially trained personnel and techniques needed to assess patients for CMD — which, the researchers noted, limits the feasibility of performing these assessments in general practice.
Challenging Research
Commenting on the research, Aarti Sarwal, MD, professor of neurology and section chief, Neurocritical Care, Virginia Commonwealth University, Richmond, Virginia, noted that this was a “very challenging” study to perform, given that only a few academic centers are equipped to perform both fMRI and quantitative EEG analysis.
“In general, finding patients this far out, who have access to clinical, radiological, and electrophysiological testing and were provided good care enough to receive these, is a mammoth task in itself.”
Dr. Sarwal said the study builds on efforts of the Curing Coma campaign , a clinical, scientific, and public health effort of the Neurocritical Care Society to tackle the concept of coma as a treatable medical entity.
“It continues to highlight the challenges of prognostication in acute brain injured patients by showing a higher presence of cognitive function than previously perceived,” she said.
Dr. Sarwal believes that the study’s largest impact is underscoring the need for more research into understanding the degree and quality of cognitive processing in patients with a disorder of consciousness. But it also underlines the need for a “healthy debate” on the cost/benefit analysis of pursuing such research, given the limited number of patients with access to resources.
“This debate needs to include the caregivers and families outside the traditional realms of stakeholders overseeing the science.”
Although communication with comatose patients is still “a ways away,” this research is “a step in the right direction,” said Dr. Sarwal.
The study was funded by the James S. McDonnell Foundation and others. Dr. Schiff and Dr. Sarwal report no relevant financial disclosures.

FROM THE NEW ENGLAND JOURNAL OF MEDICINE
Recommendations From a Pediatric Dermatologist on Using AI in Daily Practice
TORONTO — with the various AI models.
He reminds doctors that many of their colleagues and patients and their families are already using these systems, “and you don’t want to be left behind.”
In an interview following his presentation on AI at the annual meeting of the Society for Pediatric Dermatology (SPD), Dr. Yan discussed his tips for using AI.
Changing Fast
From the outset, most generative AI systems have been very good at processing language — for example, generating letters of medical necessity and summarizing disease processes into lay terms. But now they’re becoming “truly multimodal,” said Dr. Yan. “You can enter images; you could have it process audio; you can even start to have it refine video.”
To get started, he recommends signing up for a free account with ChatGPT, Gemini, Perplexity, Claude, and/or Microsoft Copilot. “To make the best choice, you have to try them out yourself because they each have their own kind of flavor and strengths and weaknesses,” said Dr. Yan.
Personally, he finds that ChatGPT is the most versatile, Gemini perhaps a little better in terms of image generation, and Perplexity probably the best at references because it was designed as an online library.
Once you figure out which platforms you prefer, consider signing up for a premium subscription, which is typically month to month and can be canceled at any time, Dr. Yan said. “This will allow you to get the most out of the AI model.”
As these AI systems are based on large language models, they are excellent at text, Dr. Yan noted. He suggests asking one to generate a letter or patient instruction sheet. “If you have a premium model, give it a PDF to summarize an article or take a photo of something that you want its opinion on.”
Privacy Critical
Always pay attention to privacy issues and avoid entering any private health information that would violate the Health Insurance Portability and Accountability Act (HIPAA), he said.
“We have to be very careful about how we interact with AI,” said Dr. Yan. “We can’t be posting private patient health information into these systems, no matter how useful these systems are.” Many academic institutions are creating “walled gardens” — private areas of AI access that don’t allow patient information to “leak out,” he said. “These AI models may have HIPAA protections in place and come with specific guidelines of use.”
The AI “scribe,” which helps with electronic health record documentation, is one of the most useful tools for clinicians, he said. He referred to a recent study showing that an AI scribe saved users an average of 1 hour at the keyboard every day, and a small patient survey showing 71% reported that it led to spending more time with their physician.
When entering requests into a prompt line with an AI system, Dr. Yan stressed that these prompts need to be clear and concise. For a complicated calculation or multistep problem, try adding the words “let’s do this step by step,” he said. “This is a technique invoking a ‘chain of thought’ that allows the system to enhance its accuracy when solving problems.”
If the response is not satisfactory, try being more detailed in the request, he advised, and consider giving the system examples of what you’re looking for and telling it what you don’t want in the output.
“For instance, if you’re asking for a differential diagnosis of rashes that affect the hands and feet, you can stipulate that you only want rashes that are vesicular or that arise in neonates, so you can get a more focused answer,” said Dr. Yan.
If there are “long-winded verbose” responses, add the phrase “be concise,” and it will shorten the response by about 50%, he added.
AI Hallucinations
Dr. Yan broached an issue that occasionally comes up, AI hallucinations, which refer to inaccurate or misleading responses on the basis of incomplete training or intrinsic biases within the model. He pointed to the case of a doctor discussing issues related to a patient’s hands, feet, and mouth, which the AI-generated model summarized as “the patient being diagnosed with hand, foot, and mouth disease.”
Another example he provided was a request to generate a letter of medical necessity for using ustekinumab (Stelara) for treating hidradenitis suppurative in a child that included references for its effectiveness and safety in children. The AI system generated “false references that sounded like they should be real because the authors are often people who have written in that field or on that subject,” said Dr. Yan.
When pressed, the system did acknowledge the references were hypothetical but were meant to illustrate the types of studies that would typically support the use of this drug in pediatric patients with HS. “ It’s well meaning, in the sense that it’s trying to help you achieve your goals using this training system,” said Dr. Yan.
“If you’re skeptical about a response, double-check the answer with a Google search or run the response through another AI [tool] asking it to check if the response is accurate,” he added.
While AI systems won’t replace the clinician, they are continuing to improve and becoming more sophisticated. Dr. Yan advises keeping up with emerging developments and engaging and adapting the most appropriate AI tool for an individual clinician’s work.
Asked to comment on the presentation at the SPD meeting, Sheilagh Maguiness, MD, director of the Division of Pediatric Dermatology at the University of Minnesota, Minneapolis, who, like other doctors, is increasingly testing AI, said she foresees a time when AI scribes fully replace humans for completing tasks during patient interactions.
“The hope is that if the AI scribes get good enough, we can just open our phone, have them translate the interaction, and create the notes for us.”
While she likes the idea of using ChatGPT to help with tasks like letters of recommendation for medications, Dr. Yan’s comments reiterated the importance of “checking and double-checking ChatGPT because it’s not correct all the time.” She particularly welcomed the advice “that we can just go back and ask it again to clarify, and that may improve its answers.”
Dr. Yan’s disclosures included an investment portfolio that includes companies working in the AI space, including Google, Apple, Nvidia, Amazon, Microsoft, and Arm. Dr. Maguiness had no relevant disclosures.

TORONTO — with the various AI models.
He reminds doctors that many of their colleagues and patients and their families are already using these systems, “and you don’t want to be left behind.”
In an interview following his presentation on AI at the annual meeting of the Society for Pediatric Dermatology (SPD), Dr. Yan discussed his tips for using AI.
Changing Fast
From the outset, most generative AI systems have been very good at processing language — for example, generating letters of medical necessity and summarizing disease processes into lay terms. But now they’re becoming “truly multimodal,” said Dr. Yan. “You can enter images; you could have it process audio; you can even start to have it refine video.”
To get started, he recommends signing up for a free account with ChatGPT, Gemini, Perplexity, Claude, and/or Microsoft Copilot. “To make the best choice, you have to try them out yourself because they each have their own kind of flavor and strengths and weaknesses,” said Dr. Yan.
Personally, he finds that ChatGPT is the most versatile, Gemini perhaps a little better in terms of image generation, and Perplexity probably the best at references because it was designed as an online library.
Once you figure out which platforms you prefer, consider signing up for a premium subscription, which is typically month to month and can be canceled at any time, Dr. Yan said. “This will allow you to get the most out of the AI model.”
As these AI systems are based on large language models, they are excellent at text, Dr. Yan noted. He suggests asking one to generate a letter or patient instruction sheet. “If you have a premium model, give it a PDF to summarize an article or take a photo of something that you want its opinion on.”
Privacy Critical
Always pay attention to privacy issues and avoid entering any private health information that would violate the Health Insurance Portability and Accountability Act (HIPAA), he said.
“We have to be very careful about how we interact with AI,” said Dr. Yan. “We can’t be posting private patient health information into these systems, no matter how useful these systems are.” Many academic institutions are creating “walled gardens” — private areas of AI access that don’t allow patient information to “leak out,” he said. “These AI models may have HIPAA protections in place and come with specific guidelines of use.”
The AI “scribe,” which helps with electronic health record documentation, is one of the most useful tools for clinicians, he said. He referred to a recent study showing that an AI scribe saved users an average of 1 hour at the keyboard every day, and a small patient survey showing 71% reported that it led to spending more time with their physician.
When entering requests into a prompt line with an AI system, Dr. Yan stressed that these prompts need to be clear and concise. For a complicated calculation or multistep problem, try adding the words “let’s do this step by step,” he said. “This is a technique invoking a ‘chain of thought’ that allows the system to enhance its accuracy when solving problems.”
If the response is not satisfactory, try being more detailed in the request, he advised, and consider giving the system examples of what you’re looking for and telling it what you don’t want in the output.
“For instance, if you’re asking for a differential diagnosis of rashes that affect the hands and feet, you can stipulate that you only want rashes that are vesicular or that arise in neonates, so you can get a more focused answer,” said Dr. Yan.
If there are “long-winded verbose” responses, add the phrase “be concise,” and it will shorten the response by about 50%, he added.
AI Hallucinations
Dr. Yan broached an issue that occasionally comes up, AI hallucinations, which refer to inaccurate or misleading responses on the basis of incomplete training or intrinsic biases within the model. He pointed to the case of a doctor discussing issues related to a patient’s hands, feet, and mouth, which the AI-generated model summarized as “the patient being diagnosed with hand, foot, and mouth disease.”
Another example he provided was a request to generate a letter of medical necessity for using ustekinumab (Stelara) for treating hidradenitis suppurative in a child that included references for its effectiveness and safety in children. The AI system generated “false references that sounded like they should be real because the authors are often people who have written in that field or on that subject,” said Dr. Yan.
When pressed, the system did acknowledge the references were hypothetical but were meant to illustrate the types of studies that would typically support the use of this drug in pediatric patients with HS. “ It’s well meaning, in the sense that it’s trying to help you achieve your goals using this training system,” said Dr. Yan.
