New Hope for Fading Memories: Alzheimer's Disease

Author(s): Ronald McNeel DrPH

Pathology of Alzheimer's Disease (AD)

Alzheimer's Disease (AD) is the most common form of dementia, a brain disorder that affects a person's ability to carry out routine activities. On average, patients survive about 8-10 years after being diagnosed with AD. Symptoms of AD arise as nerve cells die in areas of the brain necessary for memory, or as nerve cell connections are disrupted. As more nerve cells die, the brain shrinks and memory is lost.
