In 2024, health and long-term care costs for people living with Alzheimer’s and other dementias are projected to reach $360 billion. Nearly 7 million American seniors are living with Alzheimer’s dementia, placing a huge strain on both personal caregivers and the U.S. health care system, according to a new Alzheimer’s Association report. Alzheimer’s disease was the fifth-leading cause of death among individuals aged 65 and older in 2021.
