Some worry that many elderly who display normal forgetfulness and other common features of growing older will incorrectly receive this diagnosis.

Alzheimer's disease is a form of dementia that causes problems with memory. Alzheimer's accounts of 60-80 % of dementia cases and interferes with normal life. It is not a normal part of aging, even though people think that old people are forgetful. Alzheimer's usually starts with difficulty remembering newly learned information. Memory loss is not necessarily Alzheimer's.
