Alzheimer's Life Expectancy

Alzheimer's disease reduces a person's life expectancy.

Among people who are 70 years old, only 30 percent are expected to die before they turn 80 if they don't have Alzheimer's.

But this number jumps to 61 percent for people with Alzheimer's, according to a 2014 report in the journal Alzheimer's & Dementia.

According to the Centers for Disease Control and Prevention (CDC), Alzheimer's disease is the fifth leading cause of death in the United States among people ages 65 and older - and the fifth leading cause of death overall.
