Alzheimer’s Disease Brochure

Alzheimer’s disease is a form of dementia. Dementia is a term that doctors use for symptoms of declining brain function. Memory loss can be the first sign of dementia, but as it progresses, dementia can rob a person of the ability to think clearly and process information normally. Dementia can also cause changes in personality and behavior.

Experts believe that abnormal deposits of two brain chemicals—called amyloid-beta and tau—are responsible for the death of some brain cells that occurs in Alzheimer’s.
