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.
In advanced stages, people with Alzheimer disease may lose all memory and mental abilities. Alzheimer disease is the most common form of dementia. About 5 million Americans have Alzheimer disease, and this number is expected to grow as the population gets older. The disease progress is different for each person. If Alzheimer disease comes on quickly, it usually gets worse quickly.
