Common Gene Variant Doubles Dementia Risk, But Only in Men

New research reveals that men who carry two copies of a common genetic variant in the HFE gene are more than twice as likely to develop dementia, while women with the same variant are not affected. The variant, known as H63D, is linked to haemochromatosis and is present in about 1 in 36 people.

Depression Across Life Linked to Greater Dementia Risk

A comprehensive new analysis reveals that depression significantly increases the risk of developing dementia, whether it begins in midlife or later in life. Researchers reviewed and re-analyzed data from dozens of studies to clarify when depression most strongly affects dementia risk.

Sleep Aid May Protect Brain from Alzheimer’s Damage

A common sleep medication, lemborexant, may do more than promote rest—it appears to reduce harmful tau buildup and protect the brain from neurodegeneration in mouse models of Alzheimer’s disease. Researchers found that this orexin receptor antagonist not only restored healthier sleep patterns but also preserved brain structure and reduced inflammation.

Decoding Brain Aging: A 10-Year Study Opens Data for Discovery

A decade-long brain health study has released its full dataset, offering rare longitudinal insights into how cognition and brain structure change across adulthood. The Dallas Lifespan Brain Study tracked nearly 500 individuals from age 21 to 89 over three timepoints using brain scans, cognitive tests, and health surveys.

Link Found Between Autism and Early-Onset Parkinson’s Risk

A large-scale Swedish study has found that individuals with autism are at significantly higher risk of developing early-onset Parkinson’s disease. Researchers followed over two million people and discovered that those with autism were four times more likely to develop the neurodegenerative condition before age 50.

Daylight Boosts Immune Defense

Researchers have discovered that daylight enhances the infection-fighting power of neutrophils, the most abundant white blood cells in the body. Using transparent zebrafish, scientists observed that these immune cells contain internal circadian clocks that are activated by light, boosting their bacterial-killing ability during the day.

Chronic Stress Quietly Raises Your Stroke Risk

Chronic stress is increasingly recognized as a contributor to stroke risk by intensifying conditions like high blood pressure, inflammation, and unhealthy lifestyle habits. While stress isn't as easily measured as cholesterol or blood pressure, long-term exposure to it can set the stage for vascular damage and increase both ischemic and, less commonly, hemorrhagic stroke risk.

Dementia Diagnoses Decline, But More Are Living Longer With the Disease

A new study of over 25 million Medicare recipients found that while dementia incidence in the U.S. is declining, more older adults are living longer with the condition. From 2015 to 2021, new diagnoses dropped from 3.5% to 2.8%, yet prevalence increased to nearly 12%.

ALS Drug Shows Unprecedented Recovery in Patients With Rare Mutation

A groundbreaking experimental therapy for a rare, aggressive form of ALS caused by FUS gene mutations has produced surprising clinical improvements in some patients, including restored mobility and extended survival. The treatment uses antisense technology to silence the FUS gene, reducing toxic protein buildup in motor neurons. Two patients in a recent case series showed remarkable responses—one regained the ability to walk and breathe unassisted, while another has remained symptom-free for three years.

Placebo Triggers Brain’s Opioid System to Relieve Pain

Researchers have successfully induced the placebo effect in rats, uncovering the neural mechanisms behind how belief in pain relief can reduce the perception of pain. Using conditioning, rats learned to associate injections with pain relief, and later exhibited reduced pain responses even when injected with saline.

Billy Joel Diagnosed with Normal Pressure Hydrocephalus: What is NPH?

Billy Joel has revealed a diagnosis of normal pressure hydrocephalus (NPH), a rare but potentially reversible brain disorder that causes symptoms like gait disturbance, cognitive decline, and urinary incontinence. NPH occurs when cerebrospinal fluid builds up in the brain's ventricles without increased pressure, often mimicking dementia or Parkinson’s.

Eye Surgery Technique Could Restore Vision in Macular Degeneration

Scientists have developed a novel surgical method allowing two retinal tissue grafts to be implanted in a single eye, advancing treatment strategies for dry age-related macular degeneration (AMD). This new approach enables side-by-side testing of grafts—one with retinal pigment epithelial (RPE) cells and one without—within the same lesion, using a specially designed clamp to maintain eye pressure and reduce damage.
