What is Alzheimer's Disease?

Alzheimer's is marked by the loss of cognitive ability, generally over a period of 10 to 15 years and is associated with the development of abnormal tissues and protein deposits in the cerebral cortex.

According to Women & Alzheimer's disease by National Women's Health Report, 5 million Americans in the U.S. have Alzheimer's and more than half of them are women.

Alzheimer's Disease is the fourth leading cause of death in adults, after heart disease, cancer and stroke.  The disease was first described by Dr. Alois Alzheimer in 1906.

Identified risk factors are age and family history.  Most people diagnosed with Alzheimer's are older than 65. However, Alzheimer's can develop in people in their 30's, 40's, 50's.
