Frequently Asked Questions

3. How many people in the United States have Alzheimer's disease?

Estimates vary, but experts suggest that as many as 5.1 million people in the United States may have Alzheimer's disease. Symptoms usually begin after age 60, and the risk of developing the disease increases with age. While younger people in their thirties and forties also may get Alzheimer's disease, it is much less common. It is important to note that Alzheimer's disease is not a normal part of aging.
