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.
During that time, 438 of the study participants developed Alzheimerâs disease or another form of dementia, and more than 80 percent of those with dementia died. Overall, men with dementia did not live as long as women with the disease: 4.1 years for men, versus 4.6 years for women. And men or women in frail physical shape did not tend to live as long as their more physically robust peers. Itâs important to note that these numbers mainly reflect people in their 80s and 90s.
