The symptoms of Alzheimer's disease worsen over time, although the rate at which the disease progresses varies. On average, a person with Alzheimer's lives four to eight years after diagnosis, but can live as long as 20 years, depending on other factors.
Thatâs because the risk of Alzheimerâs increases with age, and the U.S. population is aging. Alzheimerâs is a slow disease that progresses in three stagesâan early, preclinical stage with no symptoms, a middle stage of mild cognitive impairment, and a final stage of Alzheimerâs dementia.
