In 2026, an estimated 7.4 million Americans age 65 or older are living with clinical Alzheimer's dementia. That is about one in nine older adults, with consequences for families, care systems, and public spending. "Clinical Alzheimer's dementia" means the estimate is based on symptoms consistent with Alzheimer's, not biomarker confirmation. The figure should not be read as a confirmed count of every American with Alzheimer's across all ages.

Who makes up the 7.4 million?
The Alzheimer's Association's 2026 report estimates that 74% of older Americans with clinical Alzheimer's dementia are at least 75 years old. Prevalence rises sharply with age: from 5.2% among people ages 65–74 to 35.8% among those 85 and older. Women account for an estimated 4.5 million cases, compared with 2.9 million among men.
The difference partly reflects women's longer average survival, so it should not be interpreted as a simple measure of biological risk. These numbers show why the national total can feel distant from a family's experience. Alzheimer's is not evenly distributed across older adulthood; the burden becomes much more concentrated at advanced ages.
What does the estimate mean for families?
Nearly 13 million Americans provide unpaid care to someone with Alzheimer's or another dementia. According to the Alzheimer's Association's national facts and figures, they delivered more than 19 billion hours of care in 2025, valued at more than $446 billion. That unpaid work may include supervision, transportation, household tasks, personal care, or coordination with paid services.
The scale matters because a prevalence statistic counts people with dementia, but it does not count everyone whose daily life changes around them. It also means families should plan for more than medical appointments. Decisions may involve who coordinates care, how responsibilities are shared, and how future needs will be funded.
How large is the financial and health burden?
U.S. health and long-term-care costs for people with Alzheimer's or other dementias are projected to reach $409 billion in 2026. medicare and Medicaid are expected to pay $263 billion, while out-of-pocket spending is projected at $103 billion. Those figures cover Alzheimer's and other dementias, not Alzheimer's alone. They also exclude unpaid care, so they describe a different part of the burden than the $446 billion valuation of family caregiving.
The two totals refer to different years and categories and should not be casually combined. Alzheimer's also has a substantial mortality impact. CDC finalized data record 116,022 U.S. deaths from Alzheimer disease in 2024, making it the sixth-leading cause of death overall. Death certificates may undercount it when Alzheimer's is not recorded.
How certain is the 7.4 million estimate?
The 7.4 million figure is an estimate, not a direct national head count. It comes from a linear extrapolation between projections for 2025 and 2030 developed from the Chicago Health and Aging Project. It is also based on clinical symptoms rather than biological markers associated with the disease.
Biomarker-confirmed prevalence is likely lower, which makes the wording "clinical Alzheimer's dementia" essential when citing the number. The estimate is still useful for planning, provided its limits remain visible. Without breakthroughs that prevent or cure the disease, the number of Americans age 65 and older with clinical Alzheimer's dementia is projected to reach 13.8 million by 2060.
What can individuals and families do now?
Alzheimer's is progressive and irreversible, but an early, accurate diagnosis can give people and families more time to make informed decisions. The CDC's Alzheimer's overview identifies treatment discussions, financial planning, advance directives, clinical trials, and future care needs as reasons diagnosis matters. After concerns arise, practical next steps include:.
- Arrange an appropriate medical evaluation rather than assuming a cause.
- Ask what the diagnosis means for treatment and future care.
- Discuss financial plans and advance directives.
- Identify who will help coordinate care and major decisions.
- Ask whether relevant clinical trials should be considered.
