Untreated hearing loss increases dementia risk in middle-aged and older adults, new research confirms. A large observational study from the United Kingdom showed a 42% increased risk for dementia in people with hearing loss compared with their peers with no hearing trouble. In addition, there was no increased risk in those with hearing loss who used hearing aids.

“The evidence is building that hearing loss may be the most impactful modifiable risk factor for dementia in mid-life, but the effectiveness of hearing aid use on reducing the risk of dementia in the real world has remained unclear,” Dongshan Zhu, PhD, with Shandong University, Jinan, China, said in a news release.

“Our study provides the best evidence to date to suggest that hearing aids could be a minimally invasive, cost-effective treatment to mitigate the potential impact of hearing loss on dementia,” Dr. Zhu said.

The study, which was published online in Lancet Public Health, comes on the heels of the 2020 Lancet Commission report on dementia, which suggested hearing loss may be linked to approximately 8% of worldwide dementia cases.
 

‘Compelling’ evidence

For the study, investigators analyzed longitudinal data on 437,704 individuals, most of whom were White, from the UK Biobank (54% female; mean age at baseline, 56 years). Roughly three quarters of the cohort had no hearing loss and one quarter had some level of hearing loss, with 12% of these individuals using hearing aids.

After the researchers controlled for relevant cofactors, compared with people without hearing loss, those with hearing loss who were not using hearing aids had an increased risk for all-cause dementia (hazard ratio [HR], 1.42; 95% confidence interval [CI], 1.29-1.56).

No increased risk was seen in people with hearing loss who were using hearing aids (HR, 1.04; 95% CI, 0.98-1.10).

The positive association of hearing aid use was observed in all-cause dementia and cause-specific dementia subtypes, including Alzheimer’s disease, vascular dementia, and non–Alzheimer’s disease nonvascular dementia.

The data also suggest that the protection against dementia conferred by hearing aid use most likely stems from direct effects from hearing aids rather than indirect mediators, such as social isolation, loneliness, and low mood.

Dr. Zhu said the findings highlight the “urgent need” for the early use of hearing aids when an individual starts having trouble hearing.

“A group effort from across society is necessary, including raising awareness of hearing loss and the potential links with dementia; increasing accessibility to hearing aids by reducing cost; and more support for primary care workers to screen for hearing impairment, raise awareness, and deliver treatment such as fitting hearing aids,” Dr. Zhu said.

Writing in a linked comment, Gill Livingston, MD, and Sergi Costafreda, MD, PhD, with University College London, noted that with addition of this study, “the evidence that hearing aids are a powerful tool to reduce the risk of dementia in people with hearing loss, is as good as possible without randomized controlled trials, which might not be practically possible or ethical because people with hearing loss should not be stopped from using effective treatments.”

“The evidence is compelling that treating hearing loss is a promising way of reducing dementia risk. This is the time to increase awareness of and detection of hearing loss, as well as the acceptability and usability of hearing aids,” Dr. Livingston and Dr. Costafreda added.
 

 

 

High-quality evidence – with caveats

Several experts offered perspective on the analysis in a statement from the U.K.-based nonprofit Science Media Centre, which was not involved with the conduct of this study. Charles Marshall, MRCP, PhD, with Queen Mary University of London, said that the study provides “high-quality evidence” that those with hearing loss who use hearing aids are at lower risk for dementia than are those with hearing loss who do not use hearing aids.

“This raises the possibility that a proportion of dementia cases could be prevented by using hearing aids to correct hearing loss. However, the observational nature of this study makes it difficult to be sure that hearing aids are actually causing the reduced risk of dementia,” Dr. Marshall added.

“Hearing aids produce slightly distorted sound, and the brain has to adapt to this in order for hearing aids to be helpful,” he said. “People who are at risk of developing dementia in the future may have early changes in their brain that impair this adaptation, and this may lead to them choosing to not use hearing aids. This would confound the association, creating the appearance that hearing aids were reducing dementia risk, when actually their use was just identifying people with relatively healthy brains,” Dr. Marshall added.

Tara Spires-Jones, PhD, with the University of Edinburgh, said this “well-conducted” study confirms previous similar studies showing an association between hearing loss and dementia risk.

Echoing Dr. Marshall, Dr. Spires-Jones noted that this type of study cannot prove conclusively that hearing loss causes dementia.

“For example,” she said, “it is possible that people who are already in the very early stages of disease are less likely to seek help for hearing loss. However, on balance, this study and the rest of the data in the field indicate that keeping your brain healthy and engaged reduces dementia risk.”

Dr. Spires-Jones said that she agrees with the investigators that it’s “important to help people with hearing loss to get effective hearing aids to help keep their brains engaged through allowing richer social interactions.”

This study was funded by the National Natural Science Foundation of China and Shandong Province, Taishan Scholars Project, China Medical Board, and China Postdoctoral Science Foundation. Dr. Zhu, Dr. Livingston, Dr. Costafreda, Dr. Marshall, and Dr. Spires-Jones have no relevant disclosures.

AHA backs screening for cognitive impairment after stroke

Article Type

Fri, 05/05/2023 - 10:18

Screening for cognitive impairment should be part of multidisciplinary care for stroke survivors, the American Heart Association says in a new scientific statement.

“Cognitive impairment after stroke is very common, is associated with other post-stroke outcomes, and often has significant impact on the quality of life,” Nada El Husseini, MD, MHSc, chair of the scientific statement writing group, told this news organization.

“It is important to screen stroke survivors for cognitive impairment as well as for associated comorbidities such as mood and sleep disorders,” said Dr. El Husseini, associate professor of neurology at Duke University Medical Center in Durham, N.C.

The scientific statement was published online in Stroke. It’s the first to specifically focus on the cognitive impairment resulting from an overt stroke (ischemic or hemorrhagic).
 

‘Actionable’ considerations for care

The writing group performed a “scoping” review of the literature on the prevalence, diagnosis, and management of poststroke cognitive impairment (PSCI) to provide a framework for “actionable considerations” for clinical practice as well as to highlight gaps needing additional studies, Dr. El Husseini explained.

PSCI, ranging from mild to severe, occurs in up to 60% of stroke survivors in the first year after stroke; yet, it is often underreported and underdiagnosed, the writing group notes.

Up to 20% of stroke survivors who experience mild cognitive impairment fully recover cognitive function, and cognitive recovery is most likely within the first 6 months after a stroke.

However, improvement in cognitive impairment without return to prestroke levels is more frequent than is complete recovery. As many as one in three stroke survivors may develop dementia within 5 years of stroke.

The writing group also notes that PSCI is often associated with other conditions, including physical disability, sleep disorders, behavioral and personality changes, depression, and other neuropsychological changes – each of which may contribute to lower quality of life.

Currently, there is no “gold standard” for cognitive screening following stroke, but several brief cognitive screening tests, including the Mini–Mental State Examination and the Montreal Cognitive Assessment, are widely used to identify cognitive impairment after stroke.

The statement also highlights the importance of assessing cognitive changes over time after stroke. Stroke survivors who experience unexplained difficulties with cognitive-related activities of daily living, following care instructions, or providing a reliable health history may be candidates for additional cognitive screening.
 

Manage risk factors to prevent repeat stroke

“Anticipatory guidance regarding home and driving safety and, return to work (if applicable) along with interdisciplinary collaboration among different medical and ancillary specialists in the diagnosis and management of cognitive impairment is key for the holistic care of stroke survivors,” Dr. El Husseini told this news organization.

The multidisciplinary poststroke health care team could include neurologists, occupational therapists, speech therapists, nurses, neuropsychologists, gerontologists, and primary care providers.

“Because recurrent stroke is strongly associated with the development of cognitive impairment and dementia, prevention of recurrent strokes should be sought to decrease that risk,” Dr. El Husseini said. This includes addressing stroke risk factors, including high blood pressure, high cholesterol, type 2 diabetes, and atrial fibrillation.

The writing group says research is needed in the future to determine how cognitive impairment develops after stroke and the impact of nonbrain factors, including infection, frailty, and social factors.

Further research is also needed to determine best practices for cognitive screening after stroke, including the development and use of screening instruments that consider demographic, cultural, and linguistic factors in determining “normal” function.

“Perhaps the most pressing need, however, is the development of effective and culturally relevant treatments for poststroke cognitive impairment,” Dr. El Husseini said in a news release.

“We hope to see big enough clinical trials that assess various techniques, medications, and lifestyle changes in diverse groups of patients that may help improve cognitive function,” she added.

This scientific statement was prepared by the volunteer writing group on behalf of the AHA Stroke Council, the Council on Cardiovascular Radiology and Intervention, the Council on Hypertension, and the Council on Lifestyle and Cardiometabolic Health.

Head-to-head comparison of migraine meds reveals top options

Article Type
Changed
Fri, 05/05/2023 - 10:23

When it comes to relieving migraine, triptans, ergots, and antiemetics are the most effective classes of medications, a new real-world analysis of data on more than 3 million migraine attacks shows.

The findings “align with results of clinical trials and recommendations from clinical treatment guidelines” and provide insights to complement clinical practice, said study investigator Chia-Chun Chiang, MD, a neurologist with Mayo Clinic, Rochester, Minn.

The findings were presented at the 2023 annual meeting of the American Academy of Neurology.
 

The power of big data

Despite a wide variety of acute migraine medications that are available, large-scale, head-to-head comparisons of treatment effectiveness from real-world patient experience reports are lacking, Dr. Chiang explained.

“To the best of our knowledge, this is the first study that simultaneously compared multiple acute migraine medications using a Big Data analysis approach based on real-world patient-provided data,” she said.

The researchers extracted more than 10 million self-reported migraine attack records from a migraine smartphone app called Migraine Buddy, where users can document whether a treatment was helpful, somewhat helpful, unsure, or unhelpful.

They analyzed 25 acute medications among seven classes: acetaminophen, nonsteroidal anti-inflammatory drugs (NSAIDs), triptans, combination analgesics (acetaminophen/aspirin/caffeine), ergots, antiemetics, and opioids. The newer gepants and ditan medication classes of medications were not included because of the relatively lower numbers of usage when data was extracted (2014-2020).

The researchers employed a two-level nested logistic regression model to analyze the odds of treatment effectiveness of each medication by adjusting concurrent medications and the covariance within the same user.

The final analysis included more than 3.1 million migraine attacks among 278,000 users globally.

Using ibuprofen as the reference, triptans, ergots, and antiemetics had the highest efficacy with mean odds ratios of 4.8, 3.02, and 2.67, respectively, followed by opioids (OR, 2.49), NSAIDs (OR, 1.94), combination analgesics (OR, 1.69), others (OR, 1.49), and acetaminophen (OR, 0.83).

Individual medications with the highest patient-reported effectiveness were eletriptan (Relpax; OR, 6.1), zolmitriptan (Zomig; OR, 5.7) and sumatriptan (Zecuity; OR, 5.2).

This migraine medication comparative effectiveness analysis, based on patient-reported outcomes, “supports and complements the treatment recommendations from national headache societies based on randomized controlled trials and meta-analyses and strongly supports the use of triptans,” Dr. Chiang said.
 

End of trial-and-error?

Commenting on this research, Shaheen Lakhan, MD, PhD, a neurologist and researcher in Boston, said “This is a great study of Big Data in that it shows the power of the smartphone to collect real-world data and smart researchers like at Mayo Clinic to analyze them.”

“The study sheds light on how different therapeutics compare with each other. The next iteration of this line of research, I would hope, would be to determine if particular medications are effective for a particular migraine population, and even down to individuals with migraine,” said Dr. Lakhan, who wasn’t involved in the study.

“Once those models are appropriately built, long gone will be the era of trial-and-error medicine,” Dr. Lakhan added.

The study had no specific funding. Dr. Chiang has served as a consultant for Satsuma. Dr. Lakhan reports no relevant financial relationships.

The final analysis included more than 3.1 million migraine attacks among 278,000 users globally.

Using ibuprofen as the reference, triptans, ergots, and antiemetics had the highest efficacy with mean odds ratios of 4.8, 3.02, and 2.67, respectively, followed by opioids (OR, 2.49), NSAIDs (OR, 1.94), combination analgesics (OR, 1.69), others (OR, 1.49), and acetaminophen (OR, 0.83).

Individual medications with the highest patient-reported effectiveness were eletriptan (Relpax; OR, 6.1), zolmitriptan (Zomig; OR, 5.7) and sumatriptan (Zecuity; OR, 5.2).

This migraine medication comparative effectiveness analysis, based on patient-reported outcomes, “supports and complements the treatment recommendations from national headache societies based on randomized controlled trials and meta-analyses and strongly supports the use of triptans,” Dr. Chiang said.
 

End of trial-and-error?

Commenting on this research, Shaheen Lakhan, MD, PhD, a neurologist and researcher in Boston, said “This is a great study of Big Data in that it shows the power of the smartphone to collect real-world data and smart researchers like at Mayo Clinic to analyze them.”

“The study sheds light on how different therapeutics compare with each other. The next iteration of this line of research, I would hope, would be to determine if particular medications are effective for a particular migraine population, and even down to individuals with migraine,” said Dr. Lakhan, who wasn’t involved in the study.

“Once those models are appropriately built, long gone will be the era of trial-and-error medicine,” Dr. Lakhan added.

The study had no specific funding. Dr. Chiang has served as a consultant for Satsuma. Dr. Lakhan reports no relevant financial relationships.

When it comes to relieving migraine, triptans, ergots, and antiemetics are the most effective classes of medications, a new real-world analysis of data on more than 3 million migraine attacks shows.

The findings “align with results of clinical trials and recommendations from clinical treatment guidelines” and provide insights to complement clinical practice, said study investigator Chia-Chun Chiang, MD, a neurologist with Mayo Clinic, Rochester, Minn.

The findings were presented at the 2023 annual meeting of the American Academy of Neurology.
 

The power of big data

Despite a wide variety of acute migraine medications that are available, large-scale, head-to-head comparisons of treatment effectiveness from real-world patient experience reports are lacking, Dr. Chiang explained.

“To the best of our knowledge, this is the first study that simultaneously compared multiple acute migraine medications using a Big Data analysis approach based on real-world patient-provided data,” she said.

The researchers extracted more than 10 million self-reported migraine attack records from a migraine smartphone app called Migraine Buddy, where users can document whether a treatment was helpful, somewhat helpful, unsure, or unhelpful.

They analyzed 25 acute medications among seven classes: acetaminophen, nonsteroidal anti-inflammatory drugs (NSAIDs), triptans, combination analgesics (acetaminophen/aspirin/caffeine), ergots, antiemetics, and opioids. The newer gepants and ditan medication classes of medications were not included because of the relatively lower numbers of usage when data was extracted (2014-2020).

Oral antiamyloid shows disease-modifying potential Phase 3 trial underway

Fri, 05/05/2023 - 10:23

BOSTON – Results of a phase 2 study demonstrate potential Alzheimer’s disease–modifying effects of an investigational oral antiamyloid agent, represented by positive changes in plasma and imaging biomarkers of Alzheimer’s disease pathology.

Use of the drug, ALZ-801 (Alzheon), led to a significant reduction of plasma phosphorylated–tau 181 (p-tau181) , a marker of amyloid-induced neuronal injury in Alzheimer’s disease, as well as slowing of hippocampal atrophy and stabilization of cognition.

“The 12-month results of our phase 2 trial support the finding that ALZ-801 blocks misfolding of amyloid monomers and subsequent formation of neurotoxic amyloid oligomers, the key initial step in the amyloid aggregation cascade, which leads to a rapid and sustained reduction of brain neurodegeneration as measured by plasma p-tau181,” John Hey, PhD, Alzheon’s chief scientific officer, said in a statement.

“The severalfold greater reduction on the p-tau181 biomarker in plasma compared to plaque-clearing antiamyloid antibodies, combined with preservation of brain hippocampal volume and their positive correlations with cognitive benefits, further validate the disease-modifying effects of ALZ-801 in Alzheimer’s patients,” Dr. Hey added.

The results were presented at the 2023 annual meeting of the American Academy of Neurology.
 

ALZ-801 is an optimized prodrug of tramiprosate that has been shown to inhibit amyloid-beta 42 aggregation into toxic oligomers.

The ongoing phase 2 study is evaluating the effects of oral ALZ-801 (265 mg twice daily) on biomarkers of Alzheimer’s disease pathology for 84 adults with early Alzheimer’s disease who have either the APOE4/4 or APOE3/4 genotype. These genotypes represent the majority of patients with Alzheimer’s disease.

The mean age of the cohort was 69 years, and 51% are women; 70% had mild cognitive impairment, and 30% had mild Alzheimer’s disease. The mean Mini-Mental State Examination score for the cohort was 26.0. Roughly half were taking a cholinesterase inhibitor.

Significant plasma p-tau181 reduction was observed at 13 weeks. Levels were reduced by 41% by 52 weeks (P = .016). There was also a significant 5% reduction in plasma amyloid-beta 42 and 40 at 52 weeks (P = .002 and P = .005, respectively), Dr. Hey reported.

After 12 months of treatment, hippocampal atrophy was reduced by about 23%, and expansion of ventricular volume was reduced by about 15%, both in comparison with matched controls from the Alzheimer’s Disease Neuroimaging Initiative.

Composite cognitive z-score improved significantly at 13 and 26 weeks and remained above baseline at 52 weeks in comparison with matched ADNI controls. “These are very promising data,” Dr. Hey told conference attendees.

He noted that the safety profile of ALZ-801 remains favorable and consistent with prior safety data. Common adverse events were mild nausea and SARS-CoV-2 infection. There were no drug-related serious events or amyloid-related imaging abnormalities–edema (ARIA-E).

The phase 3 APOLLOE4 study of ALZ-801 is underway. This double-blind, randomized study is comparing oral ALZ-801 with placebo over 78 weeks for roughly 300 adults with early Alzheimer’s disease who have the APOE4/4 genotype. APOLLOE4 is expected to be completed in mid 2024.

The APOLLOE4 study is supported by a $47 million grant from the National Institute on Aging. The U.S. Food and Drug Administration has granted ALZ-801 fast-track designation.
 

 

 

More accessible option?

Reached for comment, Percy Griffin, PhD, Alzheimer’s Association director of scientific engagement, noted that the “biggest difference between this drug and others is that it is taken orally, rather than delivered through an infusion. This is important and valuable for reducing patient and caregiver burden and increasing ease of use and access.”

It’s also noteworthy that ALZ-801 was not associated with ARIA-E, “which has been reported in other antiamyloid trials and can occasionally be serious,” Dr. Griffin said.

Overall, he said the results are “encouraging, but more work is needed. If studies results continue to be positive, this treatment may provide a more accessible option for people who are at higher risk of ARIA,” Dr. Griffin said.

The study was funded by Alzheon. Dr. Hey is an employee of Alzheon and holds stock in the company. Dr. Griffin has disclosed no relevant financial relationships.

FDA expands atogepant approval to include chronic migraine

Article Type
Changed
Tue, 05/02/2023 - 11:59

The Food and Drug Administration has approved an expanded indication for atogepant (Qulipta, Abbvie) to include prevention of chronic migraine in adults. The approval makes atogepant the first, and only, oral calcitonin gene-related peptide receptor antagonist approved to prevent migraine across frequencies, including episodic and chronic, the company said in a news release.

The FDA initially approved atogepant in 2021 for the prevention of episodic migraine in adults.

Once-daily atogepant is available in three doses – 10 mg, 30 mg, and 60 mg – for prevention of episodic migraine. However, only the 60-mg dose of medication is indicated for the preventive treatment of chronic migraine.

The expanded indication in chronic migraine is based on positive results of the phase 3 PROGRESS trial, which evaluated atogepant in more than 700 adults with chronic migraine.

The trial met the primary endpoint of statistically significant reduction from baseline in mean monthly migraine days with atogepant compared with placebo across the 12-week treatment period.

Treatment with atogepant also led to statistically significant improvements in all six secondary endpoints, including the proportion of patients that achieved at least a 50% reduction in mean monthly migraine days across 12 weeks and improvements in function and reduction in activity impairment caused by migraine.

The efficacy results are consistent with those in the ADVANCE episodic migraine trial.

The overall safety profile of atogepant is consistent with the episodic migraine patient population, with the most common adverse events including constipation, nausea, and fatigue/sleepiness.

“The FDA approval is an important milestone, providing those most impacted by migraine with a new, safe, and effective treatment option in a convenient, once-daily pill,” Peter McAllister, MD, director of the New England Center for Neurology and Headache, Stamford, Conn., said in the news release.

The data demonstrate that atogepant “helps reduce the burden of migraine by delivering improvements in function, with high response rates and sustained efficacy over 12 weeks. These are critical factors neurologists and headache specialists consider when prescribing a treatment option, particularly for those with chronic migraine,” Dr. McAllister added.

Donanemab bests aducanumab in head-to-head Alzheimer’s trial

Article Type
Changed
Mon, 05/01/2023 - 16:40

BOSTON – The investigational drug donanemab yielded greater amyloid clearance and amyloid plaque reduction than aducanumab in early, symptomatic Alzheimer’s disease, according to the results of a head-to-head study.

Nearly 40% of patients treated with donanemab had amyloid clearance at 6 months compared with less than 2% of those who received aducanumab, which was approved in 2021 amid a great deal of controversy.

Titration for donanemab progressed more quickly, with participants receiving a maximum dose twice as early as those on aducanumab, without any increase in rates of amyloid-related imaging abnormalities (ARIA) – the most common side effect of amyloid drugs.

Early results from the randomized phase 3 TRAILBLAZER-ALZ 4 trial of donanemab come just 3 months after the Food and Drug Administration denied manufacturer Eli Lilly’s request for accelerated approval for the drug.

“This study shows that the drug with the quicker titration scheme, donanemab, produced more amyloid lowering and did it without having more ARIA,” said lead investigator Stephen P. Salloway, MD, director of the Memory and Aging Program at Butler Hospital in Providence, R.I., and a professor of neurology at Brown University.

The findings were presented at the 2023 annual meeting of the American Academy of Neurology.
 

Multicenter, head-to-head trial

Donanemab received breakthrough therapy designation in 2021. The drug works similarly to aducanumab and lecanemab, which was approved earlier this year. All three bind to different parts of the amyloid molecule and stimulate an immune response to help clear amyloid plaques, although they each have a distinctive binding component.

TRAILBLAZER-ALZ 4 was conducted at 31 sites across the United States, enrolling 140 patients aged 50-85 years with early and symptomatic Alzheimer’s disease. Study participants received donanemab or aducanumab at escalating doses for 18 months.

Donanemab was titrated more quickly, with participants receiving 700 mg via IV infusion once a month for 3 months before reaching the maximum dose of 1,400 mg in the fourth month of the study.

Aducanumab titration was slower, beginning at 1 mg/kg via IV monthly for 2 months, then 3 mg/kg for another 2 months, and 6 mg/kg for 2 more months before reaching the maximum dose of 10 mg/kg in the seventh month.

After 6 months of treatment, PET scan analysis revealed that 37.9% of donanemab-treated patients achieved amyloid clearance compared with just 1.6% of those who received aducanumab (P < .001).

Among patients with intermediate tau levels (n = 27 for donanemab and n = 28 for aducanumab), 38.5% of those who received donanemab achieved amyloid clearance compared with 3.8% of patients in the aducanumab group (P = .008).

Amyloid levels were 65.2% lower in donanemab patients, while levels in those receiving aducanumab were reduced by 17.0% (P < .001). Among those with intermediate tau, amyloid levels decreased with donanemab by 63.9% and 25.4% with aducanumab (P ≤ .001).

Investigators also noted a greater reduction in plasma ptau217 with donanemab.

Adverse events were similar between groups, with 62.0% of the donanemab group and 66.7% of aducanumab-treated participants reporting an adverse event.

There were no serious adverse events due to ARIA with donanemab, but one participant in the aducanumab group had a serious adverse event linked to ARIA.

“Even though the amyloid lowering was greater with donanemab, the rate of ARIA was similar, which suggests that the speed and depth of amyloid removal is not driving ARIA,” Dr. Salloway said.

There are three other Trailblazer trials of donanemab. Unlike in similar trials, participants in all three of these studies who received the trial drug could discontinue treatment once criteria for amyloid clearance were met.

That’s precisely what happened with Trailblazer 2, the study on which Lilly based its request for accelerated approval. Ironically, that trial design also contributed to the FDA’s decision to reject that request.

The FDA required data from at least 100 patients who had received donanemab for a minimum of 1 year. While the trial included more than 100 patients, many patients discontinued treatment early after achieving the targeted amount of amyloid clearance.

“They had success, and they got punished for it, in my opinion,” Dr. Salloway said.

Final data from Trailblazer 2 is due in the next month, and if results are positive, Lilly is expected to file for full approval.
 

 

 

Questions remain

“This is an interesting study that suggests donanemab may remove amyloid faster in more people than aducanumab,” said Heather Snyder, PhD, Alzheimer’s Association vice president of medical and scientific relations, who commented on the findings.

Howard Fillit, MD, cofounder and chief science officer at the Alzheimer’s Drug Discovery Foundation, also commented on the findings. He noted that faster amyloid clearance “means less time for requiring sometimes burdensome and expensive infusions.”

Both Dr. Snyder and Dr. Fillit noted that longer-term results are needed, along with studies of whether amyloid clearance offers a protective benefit against Alzheimer’s dementia. More results from Trailblazer 4 will be reported after 12 months and again at 18 months.

“There are obviously still a lot of questions about these drugs and whether reducing amyloid plaque will actually preserve cognitive function or at least slow decline,” Dr. Fillit said.

It will also be important to understand the timing of treatment, including when anti-amyloid therapies should be administered and for how long.

“It will be important to understand how these results translate to patient care and treatment plans, should this drug receive FDA approval,” Dr. Snyder said. “Patients should have the opportunity to make a decision, alongside their physician, on a treatment path that is right for them.”

The study was funded by Eli Lilly. Dr. Salloway has been a consultant for Biogen, EISAI, Lilly, Genentech, Novo Nordisk, Prothena, and others. Dr. Snyder and Dr. Fillit have disclosed no relevant financial relationships.

BOSTON – The investigational drug donanemab yielded greater amyloid clearance and amyloid plaque reduction than aducanumab in early, symptomatic Alzheimer’s disease, according to the results of a head-to-head study.

Nearly 40% of patients treated with donanemab had amyloid clearance at 6 months compared with less than 2% of those who received aducanumab, which was approved in 2021 amid a great deal of controversy.

Titration for donanemab progressed more quickly, with participants receiving a maximum dose twice as early as those on aducanumab, without any increase in rates of amyloid-related imaging abnormalities (ARIA) – the most common side effect of amyloid drugs.

Early results from the randomized phase 3 TRAILBLAZER-ALZ 4 trial of donanemab come just 3 months after the Food and Drug Administration denied manufacturer Eli Lilly’s request for accelerated approval for the drug.

“This study shows that the drug with the quicker titration scheme, donanemab, produced more amyloid lowering and did it without having more ARIA,” said lead investigator Stephen P. Salloway, MD, director of the Memory and Aging Program at Butler Hospital in Providence, R.I., and a professor of neurology at Brown University.

The findings were presented at the 2023 annual meeting of the American Academy of Neurology.
 

Multicenter, head-to-head trial

Donanemab received breakthrough therapy designation in 2021. The drug works similarly to aducanumab and lecanemab, which was approved earlier this year. All three bind to different parts of the amyloid molecule and stimulate an immune response to help clear amyloid plaques, although they each have a distinctive binding component.

TRAILBLAZER-ALZ 4 was conducted at 31 sites across the United States, enrolling 140 patients aged 50-85 years with early and symptomatic Alzheimer’s disease. Study participants received donanemab or aducanumab at escalating doses for 18 months.

Donanemab was titrated more quickly, with participants receiving 700 mg via IV infusion once a month for 3 months before reaching the maximum dose of 1,400 mg in the fourth month of the study.

Aducanumab titration was slower, beginning at 1 mg/kg via IV monthly for 2 months, then 3 mg/kg for another 2 months, and 6 mg/kg for 2 more months before reaching the maximum dose of 10 mg/kg in the seventh month.

After 6 months of treatment, PET scan analysis revealed that 37.9% of donanemab-treated patients achieved amyloid clearance compared with just 1.6% of those who received aducanumab (P < .001).

Among patients with intermediate tau levels (n = 27 for donanemab and n = 28 for aducanumab), 38.5% of those who received donanemab achieved amyloid clearance compared with 3.8% of patients in the aducanumab group (P = .008).

Amyloid levels were 65.2% lower in donanemab patients, while levels in those receiving aducanumab were reduced by 17.0% (P < .001). Among those with intermediate tau, amyloid levels decreased with donanemab by 63.9% and 25.4% with aducanumab (P ≤ .001).

Investigators also noted a greater reduction in plasma ptau217 with donanemab.

Adverse events were similar between groups, with 62.0% of the donanemab group and 66.7% of aducanumab-treated participants reporting an adverse event.

There were no serious adverse events due to ARIA with donanemab, but one participant in the aducanumab group had a serious adverse event linked to ARIA.

“Even though the amyloid lowering was greater with donanemab, the rate of ARIA was similar, which suggests that the speed and depth of amyloid removal is not driving ARIA,” Dr. Salloway said.

There are three other Trailblazer trials of donanemab. Unlike in similar trials, participants in all three of these studies who received the trial drug could discontinue treatment once criteria for amyloid clearance were met.

That’s precisely what happened with Trailblazer 2, the study on which Lilly based its request for accelerated approval. Ironically, that trial design also contributed to the FDA’s decision to reject that request.

The FDA required data from at least 100 patients who had received donanemab for a minimum of 1 year. While the trial included more than 100 patients, many patients discontinued treatment early after achieving the targeted amount of amyloid clearance.

“They had success, and they got punished for it, in my opinion,” Dr. Salloway said.

Final data from Trailblazer 2 is due in the next month, and if results are positive, Lilly is expected to file for full approval.
 

 

 

Questions remain

“This is an interesting study that suggests donanemab may remove amyloid faster in more people than aducanumab,” said Heather Snyder, PhD, Alzheimer’s Association vice president of medical and scientific relations, who commented on the findings.

Howard Fillit, MD, cofounder and chief science officer at the Alzheimer’s Drug Discovery Foundation, also commented on the findings. He noted that faster amyloid clearance “means less time for requiring sometimes burdensome and expensive infusions.”

Both Dr. Snyder and Dr. Fillit noted that longer-term results are needed, along with studies of whether amyloid clearance offers a protective benefit against Alzheimer’s dementia. More results from Trailblazer 4 will be reported after 12 months and again at 18 months.

“There are obviously still a lot of questions about these drugs and whether reducing amyloid plaque will actually preserve cognitive function or at least slow decline,” Dr. Fillit said.

It will also be important to understand the timing of treatment, including when anti-amyloid therapies should be administered and for how long.

“It will be important to understand how these results translate to patient care and treatment plans, should this drug receive FDA approval,” Dr. Snyder said. “Patients should have the opportunity to make a decision, alongside their physician, on a treatment path that is right for them.”

The study was funded by Eli Lilly. Dr. Salloway has been a consultant for Biogen, EISAI, Lilly, Genentech, Novo Nordisk, Prothena, and others. Dr. Snyder and Dr. Fillit have disclosed no relevant financial relationships.

New hope for adult children with ‘failure to launch’ syndrome

Article Type
Changed
Mon, 05/01/2023 - 16:41

A novel program for parents of highly dependent adult children reduces parental burden and anxiety in their offspring, a new pilot study shows.

Known as failure to launch (FTL) syndrome, the criteria for this condition include the absence of a neurodevelopmental, mental, or intellectual condition, difficulty adapting to the challenges of adulthood, and living with or at the expense of parents.

Results suggest that the program benefits families dealing with FTL, said study investigator Uri Berger, PhD, postdoctoral associate, Yale Child Study Center Anxiety and Mood Disorders Program, New Haven, Conn.

“If you encounter parents who are say 50-60 years old who have a child with FTL, you can tell them there’s something they can do; there’s work they can do even if their child is refusing to go to therapy,” he said.

The findings were presented as part of the Anxiety and Depression Association of America Anxiety & Depression conference.
 

Anxious, isolated

Estimates suggest that there are 3.3 million physically able adults with FTL and that the disorder may be on the rise. These individuals often present with mental health symptoms including anxiety, depression, and suicidality, and tend to be socially isolated.

The investigators noted that intervening is often challenging because individuals with the syndrome are frequently noncompliant with therapy, and currently there is no standard of care.

“The longer you’re isolated, the harder it is getting out of your cocoon, and when these adult children get to the point where they seek help, they’re less likely to comply,” he said. However, he noted, this is not because they are lazy; it’s that they’re “very, very anxious.”

Parents and other family members are also negatively affected. Dr. Berger noted that 15% of parents of a child with FTL equate their caregiver burden with having a family member with a chronic physical illness. “It’s huge; parents go through hell and it’s very hard on them. Many believe it is their fault and they feel a lot of shame.”

Supportive Parenting for Anxious Childhood Emotions (SPACE) is a manualized, parent-based program for childhood anxiety and obsessive-compulsive disorder. It has been tested in clinical trials and found to be noninferior to cognitive behavioral therapy for childhood anxiety.

The research adapted it to treat FTL. SPACE-FTL focuses on reducing parents’ family accommodation (FA), a descriptor for a child’s excessive dependence on their parents to help them avoid anxiety-provoking situations.

The study examined the feasibility, acceptability, and treatment satisfaction and its effect on adult child psychopathology symptoms, parents’ FA, and the paternal burden of caring for adult children.

The study included parents (mean age, 59.46 years; 85% female) of 40 adult children with FTL (mean age, 23.51 years; 20% female) from across the United States.

Parents were randomized to a 13-week wait-list or the SPACE-FTL program, which involves 13-20 therapy sessions, depending on the need. The average number of sessions in the study was 15. The program has five key components:

  • Providing information emphasizing FTL as not a character flaw but a problem with anxiety.
  • Helping parents identify how they accommodate their child’s behavior, and facilitating an environment that encourages independence.
  • Getting parents to show acceptance and confidence in their child who’s trying to overcome anxiety when, for example, they seek employment, instead of being overprotective and demanding.
  • Focusing on change nonconfrontationally.
  • Involving other family, community members, and professionals who can support the parent, child, or both.
 

 

The recruitment, treatment sessions, and assessments were all done online. Most participants rated the intervention as highly satisfactory on the Client Satisfaction Questionnaire (CSQ-8; mean score, 27.7 out of a maximum of 32). About 60% of the offspring no longer met full criteria for FTL (P < .001; Cohen’s D = 1.76).

All children of the wait-listed parents still met criteria for FTL.

FTL symptoms decreased significantly in the offspring of the intervention group, as seen in both in the Adult Entitled Dependence Scale (AED; P < .05; Cohen’s D = 0.84); and the Adaptive Behaviors Scale (ABS; P < .05; Cohen’s D = 0.70).

There was no change in anxiety as assessed by the Adult Behavior Checklist (ABCL). But Dr. Berger noted that child anxiety is difficult to assess through parental report.

“This population is self-isolating and parents sometimes don’t know what’s going on,” and ABCL measures may not be “as sensitive as we would have liked them to be,” Dr. Berger said.

Parental burden was significantly decreased as measured by the Zarit Burden Interview (ZBI; P < .05; Cohen’s D = 0.70). In addition, family accommodation decreased significantly as determined by the Family Accommodation Scale–Anxiety (FASA; P < .05; Cohen’s D = 0.70).
 

Innovative work

In a comment, Jonathan E. Alpert, MD, PhD, chair, department of psychiatry and behavioral sciences, and professor of psychiatry, neuroscience, and pediatrics, Albert Einstein College of Medicine, New York, described the program as “innovative.”

He noted that the SPACE-FTL approach provides parents with education and skills to reduce behaviors that reinforce their child’s avoidance of independent activities. Such behaviors “may inadvertently contribute to the adult child remaining stuck,” he said.

“Through its involvement of parents and use of a structured approach, SPACE-FTL is a very interesting step toward more evidence-based therapies.”

However, he noted that the number of study participants is still “very low” and further work is needed to better characterize this condition and develop effective therapies.

He noted that parents of adult children with FTL should not be judged or blamed. “They have been living with a worrisome problem for years and are simply doing their best to cope as any of us would do.”

In addition, he noted that some adult children aren’t capable of launching because of a serious mental illness or substance use disorder that needs treatment.

It’s unclear just how many adult children have FTL, as the condition lacks formal, agreed-upon clinical and research criteria and a reliable evidence base for treatment, Dr. Alpert said.

“Whatever the actual numbers of FTL, my anecdotal clinical experience suggests that it is a very common problem which is understudied.”

He added that the definitions of FTL should include cultural context. In some groups, it’s quite normal for adults in their 20s, 30s, or even older to live with their parents, Dr. Alpert said.

Dr. Berger and Dr. Albert report no relevant financial relationships.

Cautious optimism for new Alzheimer’s disease biomarkers and treatments, expert says

Sun, 05/07/2023 - 00:04

SAN DIEGO – Emerging biomarkers and treatments offer more options to diagnose and manage Alzheimer’s disease (AD) and related dementias, but high costs and potentially serious complications mean using them with caution, said a presenter at the annual meeting of the American College of Physicians.

Dementia prevalence is increasing as the proportion of the U.S. population older than 65 rises, said Zaldy Tan, MD, professor of neurology at Cedars-Sinai Medical Center, Los Angeles. AD deaths more than doubled between 2000 and 2018, he noted, while deaths from HIV infection, stroke, and heart disease decreased.

Most people in the United States who have AD are White, but studies suggest that, compared with Whites, the risk of AD is two times higher in Blacks and 1.5 times higher in Hispanics . “These data suggest that both genes and social determinants of health are at play,” Dr. Tan said.
 

Diagnosis of Alzheimer’s disease

The different types of dementia make it challenging for primary care physicians to identify the cause of cognitive impairment. “Even though AD is the most common type, clinicians should keep in mind that another type of dementia may be the cause of cognitive impairment,” Dr. Tan cautioned. Other dementia diagnoses include vascular, Lewy body, and frontotemporal.

Diagnostic criteria for AD include evidence of significant cognitive decline in at least one cognitive domain that interferes with independence in everyday activities, as well as the absence of another mental disorder or delirium that would explain the cognitive deficits.

“We see many patients with depressive symptoms and mild cognitive impairment, and it is not always easy to tell which of them have dementia because of the overlap in the symptoms of depression and AD,” said internist Roderick Kim, MD, of Grand Rapids, Mich., who attended the session.

It can be challenging to convince patients to undergo the appropriate diagnostic workup, Dr. Kim said. “This can delay treatment, so it is important to explain to patients that cognitive decline can progress quickly and that there are treatment options to slow it down.”
 

Why do we need biomarkers for Alzheimer’s disease?

AD is characterized by a long preclinical phase with no specific symptoms other than the typical signs and symptoms of aging, Dr. Tan said. That means cognitive impairment progresses rapidly after diagnosis in most patients with AD.

“In most cases, an accurate history, physical and neurologic examinations, basic labs, and neuroimaging are sufficient for memory loss evaluation. However, as more disease-modifying therapies come to market, biomarkers will rise in importance in primary care,” he said.

This long asymptomatic phase of AD creates the need for diagnostic biomarkers for an earlier diagnosis, he said. Amyloid-beta and tau deposits in PET images and the levels of amyloid-beta seeds, phosphorylated tau, and neurofilament light chain in the cerebrospinal fluid can be used as diagnostic biomarkers in patients with suspected AD. Emerging blood biomarkers for earlier detection include the levels of amyloid-beta1–42, phosphorylated tau, and neurofilament light chain.

With biomarkers and other new tools for the diagnosis of dementia in primary care, Dr. Tan said: “The greatest challenge is cost, as blood-based biomarkers are not currently covered by insurance and still rather costly. In addition, blood-based biomarkers will need to receive [Food and Drug Administration] approval in order to have more widespread availability.”


 

 

 

New and emerging therapies for Alzheimer’s disease

There are two classes of FDA-approved medications to manage cognitive symptoms of dementia: acetylcholinesterase inhibitors and N-methyl-D-aspartate receptor antagonists. The selections may be trial and error for each patient, Dr. Tan said.

“The approved medications can exert subtle benefits that are clinically observable. Thus, barring any contraindications or intolerance, most patients with AD would benefit from a trial of one or both of these medication classes,” said Dr. Tan. He added that it is equally important to wean off and discontinue these medications if there is intolerance or lack of a subjective or objective beneficial response.

Other medications are available for some of the most common behavioral problems associated with dementia, such as agitation, depression, and disorientation. Dr. Tan advised not to prescribe behavioral medications until nonpharmacologic interventions prove to be ineffective or impractical. Behavioral medications have many side effects, some of which are potentially serious, he said, so the risk-benefit ratio should be considered.

In his own practice, when nonpharmacologic strategies do not improve the behavioral symptoms of dementia, Dr. Tan said that, “in cases where a person is at risk of harm to themselves or others, a discussion with the patient and their caregivers about the pros and cons of medications to treat the behavior need to be had. Careful monitoring of the response and dose escalation or deprescribing when appropriate is important to keep in mind.”

Disease-modifying agents have recently provided new hope for AD treatment. Aducanumab and lecanemab, both monoclonal antibodies that target amyloids, are the first two drugs that received accelerated FDA approval for AD.

Although these monoclonal antibodies can help clear deposited amyloid plaques and show some benefit in slowing cognitive impairment in clinical trials, the real-world benefits were unclear enough for Medicare to limit coverage to people enrolled in approved studies to gather more data. Additionally, these agents can cause potentially amyloid-related imaging abnormalities, which may indicate edema, effusion, or microhemorrhage. Therefore, clinicians need to have a clear conversation of risks and benefits with patients and caregivers about these treatments.
 

Looking ahead

When asked about the most promising emerging technologies or techniques related to dementia diagnosis and management, Dr. Tan noted that multiple technology companies and start-ups are looking for new ways to detect dementia earlier or keep persons with dementia safe at home. Some devices deliver brain waves, computerized brain games or tests, automated pill dispensers, and fall monitors.

“Some of these are potentially helpful, but not every person with dementia will benefit. In addition, most of these technologies are out-of-pocket expenses for the patients and their families. It is important to know what is out there but also be cautious about outrageous claims,” he added.

Dr. Tan reported no relationships with entities whose primary business is producing, marketing, selling, reselling, or distributing health care products used by or on patients.

SAN DIEGO – Emerging biomarkers and treatments offer more options to diagnose and manage Alzheimer’s disease (AD) and related dementias, but high costs and potentially serious complications mean using them with caution, said a presenter at the annual meeting of the American College of Physicians.

Dementia prevalence is increasing as the proportion of the U.S. population older than 65 rises, said Zaldy Tan, MD, professor of neurology at Cedars-Sinai Medical Center, Los Angeles. AD deaths more than doubled between 2000 and 2018, he noted, while deaths from HIV infection, stroke, and heart disease decreased.

Most people in the United States who have AD are White, but studies suggest that, compared with Whites, the risk of AD is two times higher in Blacks and 1.5 times higher in Hispanics . “These data suggest that both genes and social determinants of health are at play,” Dr. Tan said.

Unawareness of memory slips could indicate risk for Alzheimer’s

Article Type

Fri, 04/28/2023 - 08:26

Everyone’s memory fades to some extent as we age, but not everyone will develop Alzheimer’s disease. Screening the most likely people to develop Alzheimer’s remains an ongoing challenge, as some people present only unambiguous symptoms once their disease is advanced.

A new study in JAMA Network Open suggests that one early clue is found in people’s own self-perception of their memory skills. People who are more aware of their own declining memory capacity are less likely to develop Alzheimer’s, the study suggests.

“Some people are very aware of changes in their memory, but many people are unaware,” said study author Patrizia Vannini, PhD, a neurologist at Brigham and Women’s Hospital in Boston. There are gradations of unawareness of memory loss, Dr. Vannini said, from complete unawareness that anything is wrong, to a partial unawareness that memory is declining.

The study compared the records of 436 participants in the Alzheimer’s Disease Neuroimaging Initiative, an Alzheimer’s research institute housed at the University of Southern California. More than 90% of the participants were White, and generally had a college education. Their average age was 75 years, and 53% of participants were women.

Dr. Vannini and colleagues tracked people whose cognitive function was normal at the beginning of the study, based on the Clinical Dementia Rating. Throughout the course of the study, which included data from 2010 to 2021, 91 of the 436 participants experienced a sustained decline in their Clinical Dementia Rating scores, indicating a risk for eventual Alzheimer’s, whereas the other participants held steady.

The people who declined in cognitive function were less aware of slips in their memory, as assessed by discrepancies between people’s self-reports of their own memory skills and the perceptions of someone in their lives. For this part of the study, Dr. Vannini and colleagues used the Everyday Cognition Questionnaire, which evaluates memory tasks such as shopping without a grocery list or recalling conversations from a few days ago. Both the participant and the study partner rated their performance on such tasks compared to 10 years earlier. Those who were less aware of their memory slips were more likely to experience declines in the Clinical Dementia Rating, compared with people with a heightened concern about memory loss (as measured by being more concerned about memory decline than their study partners).

“Partial or complete unawareness is often related to delayed diagnosis of Alzheimer’s, because the patient is unaware they are having problems,” Dr. Vannini said, adding that this is associated with a poorer prognosis as well.
 

Implications for clinicians

Soo Borson, MD, professor of clinical family medicine at the University of Southern California and coleader of a CDC-funded early dementia detection center at New York University, pointed out that sometimes people are genuinely unaware that their memory is declining, while at other times they know it all too well but say everything is fine when a doctor asks about their current memory status. That may be because people fear the label of “Alzheimer’s,” Dr. Borson suggested, or simply because they don’t want to start a protracted diagnostic pathway that could involve lots of tests and time.

Dr. Borson, who was not involved in the study, noted that the population was predominantly White and well-educated, and by definition included people who were concerned enough about potential memory loss to become part of an Alzheimer’s research network. This limits the generalizability of this study’s results to other populations, Dr. Borson said.

Despite that limitation, in Dr. Borson’s view the study points to the continued importance of clinicians (ideally a primary care doctor who knows the patient well) engaging with patients about their brain health once they reach midlife. A doctor could ask if patients have noticed a decline in their thinking or memory over the last year, for example, or a more open-ended question about any memory concerns.

Although some patients may choose to withhold concerns about their memory, Dr. Borson acknowledged, the overall thrust of these questions is to provide a safe space for patients to air their concerns if they so choose. In some cases it would be appropriate to do a simple memory test on the spot, and then proceed accordingly – either for further tests if something of concern emerges, or to reassure the patient if the test doesn’t yield anything of note. In the latter case some patients will still want further tests for additional reassurance, and Dr. Borson thinks doctors should facilitate that request even if in their own judgment nothing is wrong.

“This is not like testing for impaired kidney function by doing a serum creatinine test,” Dr. Borson said. While the orientation of the health care system is toward quick and easy answers for everything, detecting possible dementia eludes such an approach.

Noninvasive testing in midlife flags late-onset epilepsy risk

Article Type
Changed
Fri, 04/28/2023 - 00:35

BOSTON – Noninvasive tests performed in midlife may help identify people who are at risk of late-onset epilepsy, a new study suggests. New data from the Framingham Heart Study show those who scored better on a neurocognitive test that measures executive function were 75% less likely to develop late-onset epilepsy.

An analysis of MRI revealed that those with higher cortical volumes also had a lower risk of epilepsy later in life, while those with higher white matter hyperintensities had an increased risk.

The study could help identify at-risk individuals years before symptoms of epilepsy appear.

“We present possible markers that could potentially identify patients at risk for developing late-onset epilepsy, even in the preclinical phase and before the clinical manifestation of conditions like stroke and dementia that are known now to be linked with the condition,” said lead investigator Maria Stefanidou, MD, assistant professor of neurology at Boston University.

The findings were presented at the 2023 annual meeting of the American Academy of Neurology.
 

Protection against late-onset epilepsy?

Hypertension and stroke are known risk factors for late-onset epilepsy. Dementia is also a known risk factor. But in about 30% of cases, the cause of epilepsy in older individuals is unknown.

For this study, investigators analyzed data from the offspring cohort of the Framingham Heart Study. Participants were at least 45 years old; underwent neuropsychological evaluation and brain MRI; and had no prior history of stroke, dementia, or epilepsy. Cognitive measures included Visual Reproductions Delayed Recall, Logical Memory Delayed Recall, Similarities, Trail Making B-A (TrB-TrA), and the Hooper Visual Organization Test.

Participants also underwent an MRI to measure total cerebral brain volume, cortical gray matter volume, white matter hyperintensities, and hippocampal volume.

After a mean follow-up of 13.5 years, late-onset epilepsy was diagnosed in 31 of participants who underwent neuropsychological testing (n = 2,349) and in 27 of those who underwent MRI (n = 2,056).

Better performance on the TrB-TrA test (a measure of executive function, processing speed, and occult vascular injury) was associated with a reduced risk of late-onset epilepsy (adjusted hazard ratio, 0.25; P = .011).

The findings held even after adjusting for age, sex, educational level, and known risk factors for late-onset epilepsy, such as hypertension (aHR, 0.30; P = .0401).

Higher white matter hyperintensities, a measure of occult vascular injury, was associated with increased epilepsy risk (aHR, 1.5; P = .042) when adjusted only for age, sex, and education, but was no longer significant after adjusting for hypertension and other risk factors (aHR, 1.47; P = .065).

The analysis also revealed that participants with a higher cortical gray matter volume had a lower risk for late-onset epilepsy (aHR, 0.73; P = .001).

“There is increasing literature supporting that late-onset epilepsy may be secondary to accumulative occult cerebrovascular and neurodegenerative processes that occur during aging,” Dr. Stefanidou said. “Our findings likely reflect that a lesser degree of occult vascular brain injury in midlife may be protective against late-onset epilepsy.”

However, the epidemiological study points to association, not causation, Dr. Stefanidou cautions.

“Further studies will be needed to study our observations in the clinical setting,” she said.
 

‘Intriguing’ findings

Commenting on the findings, Joseph Sirven, MD, a neurologist at the Mayo Clinic in Jacksonville, Fla., said the findings are “intriguing,” but also raise some questions. “Late-onset epilepsy remains an issue for many and it’s common,” said Dr. Sirven, who has patients with late-onset epilepsy.

Dr. Sirven was particularly interested in the findings on white matter hyperintensities. “Hippocampal volumes have been used but not so much cortical volumes,” he said. “I would like to know more about how white matter changes suggest pathology that would explain epilepsy.”

Study funding was not disclosed. Dr. Stefanidou and Dr. Sirven report no relevant financial relationships.

BOSTON – Noninvasive tests performed in midlife may help identify people who are at risk of late-onset epilepsy, a new study suggests. New data from the Framingham Heart Study show those who scored better on a neurocognitive test that measures executive function were 75% less likely to develop late-onset epilepsy.

An analysis of MRI revealed that those with higher cortical volumes also had a lower risk of epilepsy later in life, while those with higher white matter hyperintensities had an increased risk.

The study could help identify at-risk individuals years before symptoms of epilepsy appear.

“We present possible markers that could potentially identify patients at risk for developing late-onset epilepsy, even in the preclinical phase and before the clinical manifestation of conditions like stroke and dementia that are known now to be linked with the condition,” said lead investigator Maria Stefanidou, MD, assistant professor of neurology at Boston University.

The findings were presented at the 2023 annual meeting of the American Academy of Neurology.
 

Protection against late-onset epilepsy?

Hypertension and stroke are known risk factors for late-onset epilepsy. Dementia is also a known risk factor. But in about 30% of cases, the cause of epilepsy in older individuals is unknown.

For this study, investigators analyzed data from the offspring cohort of the Framingham Heart Study. Participants were at least 45 years old; underwent neuropsychological evaluation and brain MRI; and had no prior history of stroke, dementia, or epilepsy. Cognitive measures included Visual Reproductions Delayed Recall, Logical Memory Delayed Recall, Similarities, Trail Making B-A (TrB-TrA), and the Hooper Visual Organization Test.

Participants also underwent an MRI to measure total cerebral brain volume, cortical gray matter volume, white matter hyperintensities, and hippocampal volume.

After a mean follow-up of 13.5 years, late-onset epilepsy was diagnosed in 31 of participants who underwent neuropsychological testing (n = 2,349) and in 27 of those who underwent MRI (n = 2,056).

Better performance on the TrB-TrA test (a measure of executive function, processing speed, and occult vascular injury) was associated with a reduced risk of late-onset epilepsy (adjusted hazard ratio, 0.25; P = .011).

The findings held even after adjusting for age, sex, educational level, and known risk factors for late-onset epilepsy, such as hypertension (aHR, 0.30; P = .0401).

Higher white matter hyperintensities, a measure of occult vascular injury, was associated with increased epilepsy risk (aHR, 1.5; P = .042) when adjusted only for age, sex, and education, but was no longer significant after adjusting for hypertension and other risk factors (aHR, 1.47; P = .065).
