Information on Alzheimer's Disease
Alzheimer's disease (AD) is a progressive disease of the brain that is characterized by impairment of memory and a disturbance in at least one other thinking function (for example, language or perception of reality). Many scientists believe that AD results from an increase in the production or accumulation of a specific protein (beta-amyloid protein) that leads to nerve cell death. Loss of nerve cells in strategic brain areas, in turn, causes deficits in the neurotransmitters, which are the brain's chemical messengers. Read More About Alzheimer's Disease »
