What is Alzheimer’s disease?

Alzheimer’s is a disease in which amyloid plaques build up in the brain. The plaques damage brain cells, the cells develop tangles, and the tangles destroy the cells. Alzheimer’s disease begins silently and progresses through very mild, mild, moderate, and severe stages. Age, being a woman, and family history are risk factors for the disease. Tests using a lumbar puncture or PET scan can help to confirm the diagnosis of Alzheimer’s disease, but they are only used in special circumstances. Lastly, you can reduce your risk of developing Alzheimer’s disease by eating a Mediterranean-style diet, engaging in aerobic exercise, and staying socially active.
