Alzheimer’s disease, the most common cause of dementia.
Alzheimer’s disease (AD) & Dementia
"Alzheimer’s disease is the most common cause of dementia, accounting for 60% to 80% of cases," 2020 Alzheimer’s Disease Facts and Figures is a statistical resource for U.S. data.
Alzheimer's Disease, the Most Common Cause of Dementia
The number of Americans living with Alzheimer's is growing — and growing fast. More than 5 million
According to The Alzheimer's Association, an estimated 5.8 million Americans age 65 and older are living with Alzheimer's dementia in 2020. Eighty percent are age 75 or older.
- One in 10 people age 65 and older (10%) has Alzheimer's dementia.
- Almost two-thirds of Americans with Alzheimer's are women.
- Older African-Americans are about twice as likely to have Alzheimer's or other dementias as older whites.
- Hispanics are about one and one-half times as likely to have Alzheimer's or other dementias as older whites.
As the number of older Americans grows rapidly, so too will the number of new and existing cases of Alzheimer's. By 2050, the number of people age 65 and older with Alzheimer’s dementia may grow to a projected 13.8 million, barring the development of medical breakthroughs to prevent, slow or cure Alzheimer’s disease.
