What is the average life expectancy of Alzheimer’s Disease

The average life expectancy for someone with Alzheimer’s disease is about 8 years after their symptoms first appear, however, this can range widely from as little as 3 years to as many as 20 years, depending on a number of factors such as the individual’s age, overall health, and access to proper care.

Alzheimer’s disease (AD) is a degenerative brain disorder. The disease breaks down and destroys brain cells and the neurons that connect brain cells to one another. This damage causes a decline in memory, behavior, and mental capabilities.

Every person’s journey with Alzheimer’s disease is different. For some, the disease progresses slowly and leaves mental function largely intact for several years. Other times, AD is aggressive and quickly robs people of their memory. In the end, AD becomes severe enough to disrupt day-to-day life. In later stages, people will need almost constant care.

It’s important to note that the progression of the disease can be different for each person, and some people may experience a more rapid decline while others may have a more gradual decline. Talk with your doctor about how your risk factors and lifestyle may affect your life expectancy. Work with your doctor to find the best treatments and lifestyle changes for you.
