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.
When people are diagnosed with Alzheimerâs at about age 60 or 65, they generally decline more slowly. Their life expectancy is then on the order of 12 or 14 years, and some may even live up to 20 years longer. But when people are diagnosed at age 80 or 85, their Alzheimerâs tends to progress more rapidly. Their advanced age also increases the probability of their death, and they generally survive only 5 to 8 years.
