Common signs and symptoms of Alzheimer's disease

What is Alzheimer's disease?
Basically, Alzheimer's is a severe degenerative condition that develops in the brain. The end result is a loss of the person's personality as well as his mental and physical abilities. The disease starts in the cerebral cortex. Unfortunately, Alzheimer's is a common form of dementia.

Alzheimer's stages
Alzheimer's disease is said to be a progressive illness. That means, the symptoms tend to worsen over time. There is a broad classification system called the FAST system (Functional Assessment Staging) that defines seven distinct stages of the disease. Of course, the specific symptoms at each point in time and their intensity may differ from one person to the next, so there is bound to be considerable variation within this classification.
