The number of Americans living with Alzheimer's and other Neurodegenerative diseases is growing — and growing fast.

  5.5 million Americans of all ages have Alzheimer's disease.

Of the estimated 5.5 million Americans living with Alzheimer's dementia in 2017, an estimated 5.3 million
are age  65 and older and approximately  200,000 individuals are  under age 65 and have younger - onset
Alzheimer's.

  • One in 10 people age 65 and older (10 percent) has Alzheimer's dementia.
  • Almost two-thirds of Americans with Alzheimer's are women.
  • 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.

Because of the increasing number of people age 65 and older in the United States, particularly the oldest-old, the number of new cases of Alzheimer's and other dementias is projected to soar. Today, someone in the United States develops Alzheimer's dementia every 66 seconds. By mid-century, someone in the United States will develop the disease every 33 seconds.
