Alzheimer’s Disease

The most common form of dementia, Alzheimer’s disease is irreversible and destroys brain cells, causing thinking ability and memory to deteriorate. Alzheimer’s disease is not a normal part of aging.

What is Alzheimer’s disease?

Dr. Alois Alzheimer first identified the disease in 1906. He described the two hallmarks of the disease: “plaques,” which are numerous tiny, dense deposits scattered throughout the brain that become toxic to brain cells at excessive levels, and “tangles,” which interfere with vital processes, eventually choking off the living cells. When brain cells degenerate and die, the brain markedly shrinks in some regions.
