Regular sex beneficial for men with Parkinson's

Alzheimer's has long been considered irreversible, but new research challenges that assumption. Scientists discovered that severe drops in the brain's energy supply help drive the disease, and restoring that balance can reverse damage, even in advanced cases.

A new study led by researchers at University College London (UCL) shows that chronic exposure to toxic air can significantly diminish the health benefits of regular physical activity.

Hypertension may impair the brain far earlier than previously understood -- even before a measurable rise in blood pressure occurs -- according to a new preclinical study from Weill Cornell Medicine. The changes help explain why hypertension is a major risk factor for developing cognitive disorders, such as vascular cognitive impairment and Alzheimer's disease.

About 100,000 of the estimated million persons in the United States with multiple sclerosis (MS) have a progressive form of the disease, with symptoms worsening over time or following periods of remission.

Scientists discovered that tiny messengers released by fat tissue, called extracellular vesicles, can carry harmful signals that accelerate the buildup of amyloid-b plaques in the brain.
