A protein, called beta amyloid , builds up in the brains of people with Alzheimer’s disease (AD). Cholesterol may be a factor in how much beta amyloid is produced.

You've seen them in parks or in films: rows of older men and women moving through the slow, graceful movements of tai chi. And it may be more than their bodies that they are improving.

Medications for treating Alzheimer’s disease (AD) have been suspected to influence heart function. New research finds that heart function was not affected over four weeks of treatment.

Omega-3 fatty acids are reported to protect brain cells during aging thereby protecting cognitive function. But a recent systematic review of the evidence calls into question these proposed cognitive benefits.

For the first time in humans, researchers have shown that there is a link between the immune system and age-related memory decline.

One of the world's most destructive fatal diseases is one step closer to a possible vaccine following a second trial of a vaccine for Alzheimer's disease.

Astrocytes are supporting cells that are protective and do housekeeping for neurons in the brain.  Beta amyloid build up in Alzheimer’s disease (AD) may cause the astrocytes to defend themselves.

New technologies and guidelines may help scientists better understand the Alzheimer’s Disease (AD) brain before symptoms appear, which may lead to earlier detection in future generations.

A gene, termed ApoE4 , has been linked to Alzheimer’s Disease (AD). New research begins to uncover why this gene may put people at a higher risk.

Depression is fairly common in older adults, and older adults with dementia may also suffer from depression. There may be a link between depression and risk of developing dementia.
