Brain scans reveal clues to Alzheimer's risk years before memory loss begins

Inside the brains of some cognitively normal adults, firing patterns were able to foretell Alzheimer's disease years before the onset of memory loss or the accumulation of plaques and tangles, according to new Stanford Medicine-led research.

Targeting brain protein may help treat MEF2C-related neurological disorders

A particular signaling protein in the brain could be a therapeutic target for neurological disorders arising from the deletion of the autism-linked gene MEF2C, University of Illinois Urbana-Champaign researchers found in a new mouse study.

Longer reproductive lifespan and hormonal history may influence brain vascular health

A longer reproductive lifespan and a history of using birth control pills or menopausal hormone therapy were associated with certain signs of blood vessel health in the brain, according to a study published November 4, 2026, in Neurology, the medical journal of the American Academy of Neurology.

Caffeine intake rises among Korean adults as brewed coffee gains ground

An analysis of 48,991 Korean adults found that average daily caffeine intake from beverages increased between 2016 and 2024, while the odds of consuming at least 400 mg of caffeine on a single day rose by approximately 5% annually. Coffee remained the predominant caffeine source, with a shift from prepared coffee mixes toward brewed coffee and distinct consumption patterns across age groups and sexes.

Exercise may improve mood and memory, and researchers say doctors should prescribe it

In a Viewpoint, researchers examined evidence that exercise can reduce symptoms of depression and anxiety, support cognition, and may help lower the risk of cognitive decline, although evidence for dementia prevention remains largely observational. The authors argue that exercise should be prescribed as a structured component of brain-health care, with individualized recommendations that account for medical conditions, safety, and barriers to participation.

Novel treatment clears dementia-linked proteins from the waking brain

The brain's own clearance mechanisms are most active during sleep. Researchers have now shown that this natural clearance process can also be enhanced while people are awake.

Good sleep protects brain health in people with cardiometabolic disease

People with type 2 diabetes, heart disease or stroke who sleep well have better cognitive function and greater brain volume than people with the same conditions who sleep poorly, according to a new study from Karolinska Institutet.

Eating peanuts every day may change your brains insulin response

The study finds that unsalted peanuts may enhance brain insulin responsiveness, providing new insights into dietary influences on cognitive health in aging.

Genetic family mapping uncovers hidden links across ALS and FTD

Researchers at the Macquarie University Brain Institute and Clinic have helped accelerate the search for disease-causing genes by building new genetic 'families'.

Memory problems may matter more than slower thinking for dementia risk in frail adults

In a study of 7,023 adults in England, researchers identified three cognitive frailty profiles with different patterns of memory, executive function, and processing speed impairment. Over approximately 10 years, profiles involving memory impairment were associated with higher odds of subsequent dementia, while socioeconomic, educational, and psychosocial factors showed different associations across the three groups.

Heart disease and depression may affect brain aging in an unexpected way

A longitudinal study of 5,423 adults in England found that cardiovascular disease was associated with faster cognitive decline, with the strongest association observed among participants with consistently low depressive symptoms. Those with persistent moderate or high depressive symptoms generally experienced poorer cognitive performance and faster overall deterioration, despite showing a weaker additional association between cardiovascular disease and cognitive decline.

Private equity hospice buyouts drive up Medicare spending

A study of for-profit hospices acquired by private equity firms found that Medicare spending rose by 5.9 percent per hospice stay after acquisition, compared with similar for-profit hospices that weren't acquired.

New dementia risk tool designed for the countries that need it most

An international team led by Northumbria University has developed and validated a simple five-factor risk score to identify older people at elevated risk of dementia in low- and middle-income countries (LMICs) - where around 60% of the world's dementia cases now occur.

Study identifies molecular links between menopause and brain aging

Researchers at UC Santa Barbara, UC San Francisco and international collaborators are uncovering the cascade of molecular events that happen when women undergo menopause, a time of life marked by endocrine changes and symptoms like hot flashes, brain fog and sleep disturbances.

Long-term study supports cardiovascular safety of contemporary hormone replacement therapy

Contemporary hormone replacement therapy (HRT) was not associated with an increased risk for heart attack, stroke, blood clots or death among women ages 45 to 59, according to a large, long-term study of over 52,000 women in Israel.

Scientists may have underestimated how much genes contribute to Alzheimer's risk

A large multi-ancestry genetic analysis identified 127 genomic loci associated with Alzheimer's disease, including 48 previously unreported loci, and implicated microglial and neuronal gene-expression patterns in disease susceptibility. The researchers estimated that common genetic variants account for 16% of Alzheimer's disease liability in European-ancestry populations, substantially higher than previous estimates, while demonstrating improved polygenic risk prediction that remained less reliable in non-European populations.

Study uncovers why pulmonary hypertension patients report symptoms of cognitive decline

University of Pittsburgh and UPMC researcher-clinicians have uncovered why many pulmonary hypertension patients report symptoms of cognitive decline.

Mount Sinai receives NIH grant to study advanced MRI methods for locating seizures

Researchers at the Icahn School of Medicine at Mount Sinai have received more than $3 million from the National Institutes of Health (NIH) for a five-year study of advanced magnetic resonance imaging (MRI) methods that may help locate seizure-causing brain regions in people with drug-resistant epilepsy.
