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.
Life expectancy for people with Alzheimerâs-type dementia is 8 to 12 years on average. The progression of the condition varies from one person to another and depends partly on how old the individual was at the time of diagnosis and on his or her general health.
