Alzheimer’s disease and other dementias are a well-known burden in the United States and around the world. More than 5 million Americans have Alzheimer’s, and one of every three Americans over the age of 65 dies with Alzheimer’s or another dementia.

The problem extends beyond the large and growing population of patients: caregivers play an outsize role in dementia patients’ lives. For patients with dementia, family members’ care can include bathing, dressing, shopping, transportation, helping with medications, and more. Caregivers must cope if people with Alzheimer’s become agitated or aggressive, wander away, or cause nighttime disturbances.

An estimated 15 million Americans provide unpaid care for people with Alzheimer’s and other dementias, making up 83 percent of all help provided to patients with dementias. The Alzheimer’s Association values the unpaid care for Alzheimer’s patients at $221 billion annually.
