Alzheimer’s disease facts and figures

Alzheimer’s Disease Facts and Figures is the name of an annual report published by the Alzheimer’s Association that tracks how many Americans live with Alzheimer’s, how many people care for them, what the disease costs and how it affects different communities. Its headline figure in recent years is that about 7 million Americans age 65 and older are living with Alzheimer’s dementia, roughly 1 in 9 people in that age group.

Whether you are a student writing a paper, a journalist checking a statistic or a family member trying to understand the bigger picture, the report is the most widely cited source of US numbers on the disease. This guide walks through the most important figures, explains where they come from and offers tips for using them accurately, since many numbers are updated each year.

The Big Picture in Numbers

The figures below are among the most frequently cited and come from the Alzheimer’s Association, except where noted. Always check the latest edition of the report on alz.org before quoting a specific number, because estimates are revised as new data become available.

Who Is Most Affected

Age remains the strongest risk factor, and the share of people with Alzheimer’s rises sharply in each older age group. But numbers also reveal important differences between communities. According to the Alzheimer’s Association, older Black Americans are about twice as likely, and older Hispanic Americans about one and a half times as likely, to have Alzheimer’s or other dementias as older white Americans. Researchers believe differences in rates of high blood pressure and diabetes, unequal access to health care, and social and economic factors help explain these gaps, rather than genetics alone.

Women outnumber men among people with Alzheimer’s. Part of that difference reflects the fact that women, on average, live longer, but scientists are also studying whether hormones, genetics and other biological factors play a role. Women also provide a large share of unpaid dementia care.

The Caregiving Picture

Some of the most striking figures in the report describe caregivers. Millions of spouses, adult children, other relatives and friends provide billions of hours of unpaid help each year, from managing medications and finances to bathing, dressing and supervising around the clock. The report consistently finds that dementia caregivers experience high emotional stress, and many report that their own health has suffered. Many reduce work hours, take leave or leave jobs entirely to provide care.

Costs and Health Care Use

Alzheimer’s is one of the most expensive conditions in the United States. Total payments for health care, long-term care and hospice for people with dementia amount to hundreds of billions of dollars each year, with Medicare and Medicaid covering a large share and families paying a substantial amount out of pocket. People with dementia also tend to have more hospital stays, more emergency visits and more other chronic conditions than people of the same age without dementia. Each edition of the report updates these cost estimates and projects how they may rise as the population ages. Long-term care in a nursing home or memory care community is a major expense that Medicare generally does not cover, which is why the report repeatedly urges families to learn about care costs and financial planning early.

The Special Report

Each year the publication includes a special report on a focused topic. Recent editions have examined subjects such as public attitudes toward early detection, the experiences of caregivers, the dementia care workforce and how people perceive new diagnostic tests and treatments. These sections often draw on surveys commissioned for the report and can be valuable for understanding public opinion and gaps in care.

Tips for Using the Figures Accurately

1. Name the edition year. Write the year of the report you are quoting, since numbers change.
2. Keep the age group. The headline count refers to people 65 and older; it does not include younger-onset cases.
3. Separate Alzheimer’s from all dementia. Some figures refer to Alzheimer’s specifically and others to all dementias.
4. Watch for projections. Future numbers are estimates that assume no major medical breakthroughs.
5. Link to the original. Point readers to alz.org rather than a secondhand summary.

Frequently Asked Questions

When is the Facts and Figures report released?

It is typically published each spring and is free to download from alz.org, along with a shorter fact sheet and infographics.

Where do the numbers come from?

The report pulls from government sources such as the CDC and Medicare data, large population studies and surveys commissioned by the Alzheimer’s Association.

Are death rates from Alzheimer’s undercounted?

Researchers believe so, because dementia is often not listed on death certificates when another condition, such as pneumonia, is recorded as the immediate cause.

The One Figure That Belongs to You: Your Daily Brain-Health Routine

Statistics can feel overwhelming. Millions of people, billions of hours, enormous costs. But the number that matters most in your own life is much smaller: the handful of daily habits you choose for your brain. Movement, sleep, connection, blood pressure checks and, for a growing number of people, a simple supplement. That is where Synaptigen fits in.

Synaptigen is a daily brain-health formula in convenient tablet form, created to support memory, focus and mental clarity. Its approach is built on an idea that researchers find more intriguing every year: the gut–brain axis, the constant two-way communication between your digestive system and your brain. Studies of this connection are multiplying, and it has become one of the most exciting conversations in brain-health science.

What Is Inside

• Three probiotic strains: Lactobacillus paracasei, Lactobacillus reuteri and Bifidobacterium lactis BL-04
• Inulin, a prebiotic fiber that nourishes friendly bacteria
• Strawberry extract and peppermint extract
• Tricalcium phosphate

It is a natural, non-GMO formula with no stimulants, so you get no caffeine jolt and no crash. Just one tablet a day. Synaptigen is a daily memory-support supplement intended to work alongside your doctor’s recommendations, not to replace them, which makes it an easy, upbeat addition to a brain-friendly lifestyle.

Here is the encouraging part about personal habits: unlike national statistics, they are entirely in your hands. You decide when you take your walk, when you turn off the screen for the night and when you take your daily tablet. Small, repeatable choices like these are the building blocks of a routine you can actually keep, month after month, and keeping it is what counts.
