National Facts & Figures

Alzheimer's disease is the most common form of dementia, a general term for memory loss and cognitive decline serious enough to interfere with daily life. Alzheimer's accounts for 60 to 80 percent of dementia cases. The disease causes problems with memory, thinking and behavior. Symptoms usually develop slowly and get worse over time, becoming severe enough to interfere with daily tasks. Alzheimer’s disease is our nation’s most under-recognized health crisis

Every 66 seconds, someone in America develops Alzheimer's -- resulting in nearly half a million new cases this year. By 2050, someone in the United States will develop the disease every 33 seconds. At that time, the total number of people living with Alzheimer's is projected to reach 13.8 million -- and could be as high as 16 million.
