Single Dose of Psilocybin Linked to Brain Changes; MS Patients with APOE4 Gene Show Faster Disability

Understanding the Latest Brain Health Research

Every week, scientists learn more about how our brains work and what can go wrong. This week brought several important findings that could change how doctors treat brain conditions. From psychedelics to dementia tests, here is what you need to know.

One Dose of Psilocybin May Change Brain Structure

A single 25-milligram dose of psilocybin, the active ingredient in “magic mushrooms,” was tied to lasting changes in the brain’s structure, according to a new imaging study. Researchers looked at 28 healthy volunteers who had never taken psychedelics before. The findings were published in Nature Communications.

What This Means for You

This research adds to a growing body of evidence that psychedelics might help treat mental health conditions like depression and anxiety. Experts say the brain changes seen in this study could explain why some patients feel better for weeks or months after a single dose. However, researchers caution that these drugs are not yet approved for medical use outside of clinical trials.

If you are interested in psychedelic therapy, talk to your doctor. Do not try to get these drugs on your own. They can cause serious side effects, especially in people with a history of psychosis or heart problems.

New Test May Detect a Hard-to-Find Dementia

A highly sensitive test called a digital seed amplification assay was able to detect markers of frontotemporal lobar dementia with TDP-43 in 40 samples of cerebrospinal fluid. This discovery, reported in Alzheimer’s & Dementia, could help doctors identify this form of dementia earlier.

Why This Matters

Frontotemporal dementia is often misdiagnosed because its symptoms can look like other conditions. Earlier diagnosis means patients and families can plan ahead and possibly join clinical trials for new treatments. Experts say this test is still in early stages but shows real promise for improving dementia care.

The Long Wait for a Neurologist

For people with commercial health insurance, the wait to see a neurologist is about 50 days on average. That’s according to a cross-sectional study published in Neurology.

What You Can Do

A 50-day wait can feel like forever when you are worried about your brain health. Experts suggest calling several practices to find the earliest appointment. You can also ask your primary care doctor to help manage symptoms while you wait. In some cases, telehealth visits may be available sooner.

Experimental Drug for Multiple System Atrophy Shows Mixed Results

A phase II clinical trial called AMULET tested an experimental drug called amlenetug in patients with multiple system atrophy (MSA). The drug did not meet its main goal, or primary endpoint. However, researchers noted a finding that was not statistically significant but suggested that the drug may have slowed the progression of the disease. The results appear in The Lancet Neurology.

What Experts Say

MSA is a rare and devastating brain disease that affects movement and basic body functions. There are currently no treatments that can slow it down. Experts say the AMULET trial gives them hope, even though the results were not strong enough to prove the drug works. More research is needed to see if a different dose or longer treatment period might help.

Brain Stimulation May Help Children with Autism Communicate

A study from China found that a type of brain stimulation called accelerated continuous theta burst stimulation, when aimed at the left primary motor cortex, appeared to improve social communication in children with autism. The improvement was seen one month after treatment. The trial was published in The BMJ.

Practical Takeaways

This noninvasive treatment uses magnetic fields to stimulate specific parts of the brain. It does not require surgery or medication. Experts say this approach is still experimental, but the results are encouraging. If you have a child with autism, talk to their healthcare team about whether clinical trials for brain stimulation might be available in your area.

Poor Sleep May Damage Your Brain’s Blood Vessels

Sleep habits may affect brain health as we age. In a prospective study of healthy participants from the U.K. Biobank, researchers found that self-reported sleep behaviors were linked to a greater volume of white matter hyperintensities. These are small spots on brain scans that can indicate damage to blood vessels. The findings were reported in Alzheimer’s & Dementia.

How to Protect Your Brain While You Sleep

• Aim for 7 to 9 hours of sleep each night.
• Keep a consistent sleep schedule, even on weekends.
• Avoid caffeine and screens for at least an hour before bed.
• Talk to your doctor if you snore loudly or wake up gasping for air. These could be signs of sleep apnea, which is linked to brain damage.

Older Adults Get Risky Medications in ERs and Hospitals

Older adults are more likely to get prescriptions for antipsychotics and other drugs that affect thinking and memory when they visit emergency rooms or hospitals, rather than from their regular doctor’s office. That’s the finding of research published in JAMA Network Open. These medications can be risky for older patients.

What Families Should Know

Antipsychotics and similar drugs can increase the risk of falls, confusion, and even death in older adults. Experts recommend asking doctors why a medication is being prescribed and whether there are safer alternatives. If your older family member is given one of these drugs in the hospital, ask if it is truly needed and when it can be stopped.

APOE4 Gene Linked to Faster Disability in MS Patients

A study of people with relapsing multiple sclerosis (MS) found that those who carry the APOE4 gene allele were more likely to accumulate disability from relapse-associated worsening. The findings were published in the Journal of Neurology, Neurosurgery & Psychiatry.

What This Means for MS Patients

The APOE4 gene is already known to increase the risk of Alzheimer’s disease. This study suggests it may also play a role in MS. Experts say this finding could lead to more personalized treatment plans. If you have MS, talk to your neurologist about genetic testing and what your results might mean for your care.

Remembering a Giant in Brain Research

The field of brain health lost a giant. J. Craig Venter, PhD, a renowned genomicist whose earliest breakthroughs began at the National Institute of Neurological Disorders and Stroke, died last week at age 79. He was honored by the journal Brain Health for his contributions to science.

His Legacy

Dr. Venter helped map the human genome, which laid the foundation for much of today’s brain research. His work made it possible to understand how genes affect brain diseases like Alzheimer’s, Parkinson’s, and MS. Experts say his impact will be felt for generations.

Your Brain Health Checklist

Based on this week’s findings, here are simple steps you can take today:

• Prioritize good sleep habits.
• Ask your doctor about genetic testing if you have a family history of brain disease.
• Be cautious about medications that affect thinking and memory, especially for older adults.
• Stay informed about new diagnostic tests and treatments.
• Advocate for timely appointments with specialists.
