Alzheimer's & Dementia

Alzheimer’s disease is an irreversible, progressive brain disorder that slowly destroys memory and thinking skills. Alzheimer’s is the most common cause of dementia among older adults. Dementia is the loss of cognitive functioning—thinking, remembering, and reasoning—and behavioral abilities to such an extent that it interferes with a person’s daily life and activities.

Alzheimer’s Disease | Definition, Causes, Diagnosis & Treatment

Alzheimer’s Disease (AD) is the most common form of dementia worldwide (60-70% of all dementia cases) and is a progressive neurodegenerative disorder.

Vitamin D levels in midlife tied to lower dementia risk marker

Having higher levels of vitamin D in the blood in middle age is associated with lower levels of tau protein in the brain, which is a sign of dementia, years later, according to a study published April 1, 2026, in Neurology Open Access, an official journal of the American Academy of Neurology.

Polygenic embryo testing raises ethical concerns beyond disease prevention

For more than four decades, in vitro fertilization (IVF) has helped families have children. Scientists estimate that more than 10 million people worldwide have been born through IVF and related assisted reproductive technologies, according to the International Committee for Monitoring Assisted Reproductive Technologies.

What happens when more of your exercise is vigorous instead of moderate?

In a large UK Biobank analysis, a higher proportion of vigorous physical activity relative to total activity volume was associated with lower risks of eight major chronic diseases and all-cause mortality, even after accounting for overall activity volume. Device-based data suggested that activity intensity generally offered greater preventive potential than total volume alone across most outcomes.

Study links atrial fibrillation to poorer brain clearance and cognitive decline

Researchers found that people with atrial fibrillation had lower MRI-based glymphatic activity and poorer cognitive performance than healthy controls, with the greatest impairment seen in non-paroxysmal AF. In patients who underwent catheter ablation, glymphatic activity improved after sinus rhythm was restored, suggesting a possible link between heart rhythm, brain waste clearance, and cognition.

APOE4 alters brain immunity and cognition differently in females and males

APOE4 drove sex-specific changes in meningeal immunity, lymphatic drainage, brain lipids, neuroinflammation, and cognition in mouse models, with females showing greater inflammatory and cognitive vulnerability. Suppressing innate immunity improved some cognitive outcomes in female E4/E4 mice but worsened them in male E4/E4 mice, underscoring the need for sex-tailored approaches.

Investigational drug lowers angiotensinogen but shows unclear blood pressure benefits

The investigational drug tonlamarsen—which is designed to lower blood pressure by reducing the production of angiotensinogen, a protein that turns into the hormone that regulates blood pressure—caused a significant and sustained drop in angiotensinogen but its impact on blood pressure was less clear, according to a study presented at the American College of Cardiology's Annual Scientific Session.
