Alzheimer Disease Stages

Stages of Alzheimer’s Disease

Several classifications of Alzheimer Disease stages are used to describe the degeneration of the brain and nervous system in Alzheimer’s Disease. Although these staging systems provide useful guidelines for understanding how the disease may develop, it is important to remember that each individual progresses differently.

Cognitive, physical and functional phases often overlap, the time in each stage varies widely, and not all patients experience all symptoms.

If you receive a diagnosis of Alzheimer’s Disease that includes a stage reference, it is important to understand which stages system is used.
