How many Americans have Alzheimers disease?
Scientists think that up to 4 million Americans suffer from Alzheimer’s disease. The disease usually begins after age 60, and risk goes up with age. While younger people also may get Alzheimer’s disease, it is much less common. About 3 percent of men and women ages 65 to 74 have Alzheimer’s disease, and nearly half of those age 85 and older may have the disease. It is important to note, however, that Alzheimer’s disease is not a normal part of aging.
