Memory Disorders

Alzheimer's disease (AD) is by far the biggest cause of memory loss. Approximately 60% of dementia is due to AD. First identified in 1906 by the German physician Alois Alzheimer, the Disease is characterized by pathological hallmarks of neurofibrillary tangles and accumulations of amyloid plaques.

Aging Population A disease of the aging, AD affects mostly those over the age of 65. In 1900 the average life expectancy was 47 years, so AD occurred rarely. Since then, life expectancy in the United States has increased to 77.9 years and with it so has the incidence of Alzheimer's Disease. This disease is now a major economic healthcare problem and is the most common neuronal degenerative disease of aging.
