When Alzheimer disease sets in early and impacts those under age 60, death typically occurs around 3-5 years after the first signs of the disease appear.
Alzheimer's disease is a progressive neurological disorder in which the brain atrophies and brain cells die. Alzheimer's disease is the most common cause of dementia, a continuous decline in thinking, behavioral and social skills that affect a person's ability to be independent.
About 5.8 million people over the age of 65 in the United States have Alzheimer's disease. Of these, 80% are over 75 years. Of the approximately 50 million people with dementia worldwide, it is estimated that 60% to 70% have Alzheimer's disease.
