Alzheimer's disease is a progressive, degenerative disease that attacks the brain and results in impaired memory, thinking and behavior. It was first described by Dr. Alois Alzheimer in 1906.
The disease begins gradually, perhaps with forgetfulness of recent events or of familiar tasks. Its progress is different for each individual, but eventually, there is confusion, impaired judgemtn and changes in behavior. Communication becomes difficult and frustrating, as are common tasks such as feeding oneself. Eventually most Alzheimer's patients are unable to care for themselves.
Alzheimer's disease is only one form of dementia, which means a loss of cognitive and intellectual functioning. It may also be caused by multi-infarct (strokes), Parkinson's disease, and Huntington's disease.
