Alzheimer’s Association Reports 7.4 Million Americans Age 65+ Living with Clinical Dementia in 2026

An estimated 7.4 million Americans aged 65 and older are now living with clinical dementia due to Alzheimer’s disease, according to a newly released report from the Alzheimer’s Association. The findings, published in the 2026 Alzheimer’s Disease Facts and Figures report, underscore the growing public health challenge posed by Alzheimer’s and related dementias across the United States.

The report highlights that nearly 9 in 10 Americans consider maintaining brain health as they age to be very essential, yet fewer than 1 in 10 feel knowledgeable about how to actively support it. This gap between awareness and actionable knowledge presents both a challenge and an opportunity for education and intervention.

“Now, if we really seem at the other side of it, though, we also spot that Americans believe brain health is really important, the things that we can maybe do to benefit our brain health as we age, 90% say that it’s important, although less than 10% say that they understand what to do about it. I think the good news is that people are motivated. They want information. They want to learn more and they want to have those conversations with their doctors,” said Heather M. Snyder, Ph.D., Senior Vice President, Medical & Scientific Relations, Alzheimer’s Association.

The Alzheimer’s Association emphasizes that midlife—defined as ages 40 to 64—is a critical window for adopting habits that may support long-term brain health. Many risk factors linked to cognitive decline in later life begin to emerge during these years, making early prevention strategies particularly impactful.

In Tennessee, individuals aged 65 and older continue to be diagnosed with Alzheimer’s disease, reflecting national trends. The Alzheimer’s Association Southeast Tennessee region, serving Chattanooga and surrounding counties including Bledsoe, Bradley, Grundy, Hamilton, Marion, McMinn, Meigs, and Monroe, offers local support groups, educational resources, and care navigation services for individuals living with dementia and their caregivers.

Support groups facilitated by the Alzheimer’s Association provide safe, confidential environments for caregivers and individuals living with Alzheimer’s or other dementias to share experiences, gain practical advice, and build mutual support. These groups are available in person, via phone, or through video platforms, and are led by trained facilitators. All services are free of charge.

For immediate assistance, the Alzheimer’s Association offers a 24/7 Helpline at 800.272.3900, providing guidance, emotional support, and referrals to local resources. The organization also maintains ALZConnected, an online community where individuals affected by Alzheimer’s can connect and share information around the clock.

As the number of Americans living with Alzheimer’s dementia continues to rise, the Alzheimer’s Association calls for increased investment in research, risk reduction efforts, early detection, and quality care and support services to improve outcomes for individuals and families affected by the disease.

Frequently Asked Questions

What is the difference between Alzheimer’s disease and dementia?

Dementia is a general term for a decline in mental ability severe enough to interfere with daily life, while Alzheimer’s disease is the most common cause of dementia, accounting for 60–80% of cases. Alzheimer’s is a specific neurodegenerative disease characterized by progressive memory loss, cognitive decline, and changes in behavior.

How can I find a support group near me?

You can find local support groups through the Alzheimer’s Association website by visiting the Tennessee Chapter support groups page or by calling the 24/7 Helpline at 800.272.3900 for personalized assistance.

Are Alzheimer’s Association services free?

Yes, all support groups, educational programs, care consultations, and helpline services provided by the Alzheimer’s Association are free of charge to individuals and families affected by Alzheimer’s and other dementias.

What steps can I take in midlife to support brain health?

Adopting heart-healthy habits such as regular physical activity, a balanced diet (like the Mediterranean or DASH diet), managing blood pressure and diabetes, getting quality sleep, staying socially engaged, and challenging the mind through learning or puzzles may aid support long-term brain health.
