Alzheimer’s Disease Facts and Figures 2026

The Alzheimer’s Association recently released their annual “Facts and Figures” report. It’s always a sobering collection of data, but important to document and share to increase Alzheimer’s awareness and to ensure the disease remains a high priority for funding research and care support initiatives.

Here’s a roundup of the top Alzheimer’s insights from the report:

  • More than 7 million Americans are living with Alzheimer’s.
  • 1 in 3 older adults dies with Alzheimer’s or another dementia.
  • Approximately 1 in 9 people age 65 or older has Alzheimer’s.
  • Women account for 2/3 of Alzheimer’s cases in America.
  • Race plays a role in Alzheimer’s risk, with Black Americans (twice as likely) and Hispanic Americans (1.5 times as likely) to develop the disease vs White Americans.
  • Those with Alzheimer’s or other dementias have twice as many hospital stays and more skilled nursing facility stays and home health care visits per year than other older people.
  • The lifetime cost of care for a person living with dementia is estimated at a whopping $405,262 (in 2024 dollars.) What’s worse is that 70 percent of those costs are borne by family caregivers.

The report also highlights the growing contributions of family caregivers.

  • Nearly 13 million Americans provide unpaid care for people with Alzheimer’s or other dementias.
  • About 30% of caregivers are age 65 or older.
  • Most caregivers (66%) live with the person with dementia in the community.
  • Approximately 25% of dementia caregivers are “sandwich generation” caregivers, juggling the care demands of an aging parent and at least one child.
  • Caregivers are stressed out: Nearly 60 percent of dementia caregivers report feeling high to very high emotional stress.
  • Unpaid caregivers provided more than 19 billion hours of care valued at more than $446 billion.
  • Forty-one percent of caregivers have a household income of $50,000 or less.

Below is a video synopsis of the report’s most important findings.

Based on the Alzheimer’s Association report and resources, I used NotebookLM to create an infographic of ways to protect the brain, which appears at the top of this blog post. This year’s report found that Americans have a deep interest in brain health and understand that lifestyle choices can have an impact but are unclear about how to implement them in their own lives. The good news is that supporting brain health isn’t that complex: moderate exercise, decent diet, managing stress, good sleep quality, engaging in brain-friendly hobbies like puzzles, learning new languages, or playing a musical instrument. The tough part is being consistent in implementing these healthy lifestyle choices. Every positive choice helps, so consult with your doctor to see which lifestyle change may be most beneficial for you.

Study: When it come to plant-based diets and dementia risk, quantity and quality matters

A new study finds that a plant-based diet can reduce dementia risk, but not all plant-based foods rank equal when it comes to supporting cognitive health.

The study, which was published in the journal Neurology, captured the diets of over 90,000 individuals with an average age of 59. The study included a mix of ethnicities. In a follow-up a decade later, about half of those individuals provided an update on their current diet. Researchers categorized diets into quality tiers, with diets heavy in animal fats assigned the lowest-quality tier, unhealthy processed plant-based foods like french fries and fruit juice were assigned the mid-quality tier, and whole grains, nuts, fruits and vegetables were assigned the highest-quality tier. The study was most interested in the two plant-based diet tiers and its impact, if any, on dementia risk.

What the research discovered when isolating by the highest-quality diet tier, those who ate the most healthy plant-based foods had a 7 percent lower risk of dementia than those who ate the lowest amount. So quantity does matter when it comes to a plant-based diet.

But so does quality. When reviewing data for the group that ate the greatest amount of unhealthy plant-based options, their risk of developing dementia increased 6 percent.

I have to be on a gluten-free diet and I’ve found in the last two decades, the amount of gluten-free foods readily available has exploded. But that doesn’t mean those foods are necessarily healthy. I can easily find gluten-free pizza, donuts, cookies, and sugar-laden cereal. But on the flip side, I can make a conscious effort to find healthy gluten-free food, rich in whole grains and fiber. The same thing applies to vegan and plant-based diets. We live in an age of modern convenience which can lead to us consuming overprocessed comfort foods that may technically be plant-based but are anything but healthy.

A similar recommendation applies to animal fats, as there are healthier fats and benefits from eating fish and nuts versus eating a diet heavy in red meat or unhealthy processed foods like fried chicken. I was thinking of my father this past week as April 10 marked his birthday. He battled high cholesterol beginning in middle age, but he always was a fan of fish and my mother attempted to cook comfort foods with less-processed ingredients. One thing my dad was not fond of: raw vegetables. He said crunching into them hurt his teeth. I never saw my dad eat a salad; cole slaw was the closest he ever got. In spite of his aversion to vegetables, my father always stayed trim throughout his life, due to his love of walking.

Another interesting takeaway from the new study was that making dietary changes even at an older age can still benefit cognitive health. “We found that adopting a plant-based diet, even starting at an older age, and refraining from low-quality plant-based diets were associated with a lower risk of Alzheimer’s and other dementias,” said study lead author Song-Yi Park.

The importance of heart health for the brain

February is American Heart Month, which makes it the ideal time to discuss the connection between brain and heart health.

As the American Brain Foundation states, “Heart health is brain health.”

While in the past the connection between vascular and cognitive health was not as clear, we now have a wealth of scientific evidence that captures how the cardiovascular system supports the brain. The Mayo Clinic outlines several forms of vascular dementia, some which are triggered by strokes, while other forms are the result of chronic medical conditions like diabetes or high blood pressure.

The American Brain Foundation points out that “heart disease can be a significant contributing factor to dementia”
due to its critical role in delivering blood flow that provides oxygen and other nutrients to the brain that supports cognitive health.

Heart disease is considered a risk factor for dementia. Poor heart health increases stroke risk, which can disrupt blood flow to the brain. Monitoring cholesterol levels is important because excess cholesterol can lead to blocked arteries and increase stroke risk.

The good news is that there are several lifestyle changes people can make to support their heart and brain health. Here are recommendations from the Mayo Clinic:

  • Quit smoking
  • Maintain a healthy weight
  • Prevent or manage diabetes
  • Keep your blood pressure and cholesterol levels in check with regular montioring
  • Exercise

The American Brain foundation also recommends managing stress levels and getting good sleep on a regular basis.

My father never gave up smoking until he was forced to in the memory care center but he became obsessed with cholesterol levels in midlife. It’s hard to know what caused my father’s dementia as he already had a strong family history, and I suppose my father opted to control his diet vs a habit he didn’t think he could quit. If managing heart and brain health feels overwhelming, begin by taking one small action each day and build momentum over time until it eventually becomes a healthy and sustainable lifestyle.

Alzheimer’s Association-U.S. Pointer trial finds lifestyle interventions can improve cognitive health in older adults

The Alzheimer’s Association recently released the results of a trial they funded, called the U.S. Study to Protect Brain Health Through Lifestyle Intervention to Reduce Risk (U.S. Pointer) which found that “Positive, everyday actions can make a difference in brain health, and when combined into a program that targets multiple factors like physical activity, improving nutrition, cognitive and social challenge and health monitoring, we now know it can have an even more powerful impact.”

Following a similar study that was conducted about a decade ago in Finland called the FINGER study, the Alzheimer’s Association wanted to see if that study’s findings of lifestyle changes positively impacting cognitive health could be replicated for the U.S. population. To conduct the study, participants aged 60-79 who did not exercise regularly and who were at increased risk for cognitive decline were recruited and followed for two years. Participants were located near one of the study’s site locations: Chicago, Houston, Providence, Sacramento, and Winston-Salem.

The participants were placed into one of two groups: structured lifestyle intervention and self-guided lifestyle intervention. The structured group attended nearly 40 meetings over a 2-year period while receiving a prescribed program for physical activity, diet, and cognitive training with goal setting and regular reviews and support. The self-guided group six peer team meetings and were encouraged to implement lifestyle changes that best suited them. General support was provided by staff, but no direct goal-setting or coaching was provided.

What surprised me the most about the study results is that both groups demonstrated an improvement in cognition. This is a key finding because it shows that such programs could offer benefits for those in rural, isolated areas where ongoing support services are limited or non-existent. Those in the structured program did exhibit further cognitive health benefits than the self-guided group.

Another positive finding in the study was that the benefits of the lifestyle intervention were not limited by sex, ethnicity, genetic risk or heart health status. I’ve seen studies where benefits may be more apparent in men vs. women, for example, so this is a key takeaway.

So what is the “recipe” of lifestyle interventions that was used for the study? The infographic at the top of the post captures the components:

  • Exercise: 30-35 minutes of moderate-to-intense aerobic activity four times a week, plus strength and flexibility exercises twice a week. (Strength and flexibility exercises are also critical in fall prevention for elders.)
  • Cognitive exercise: The study used a computer-based brain training program which participants used three times a week in 30-minute sessions. Regular engagement in intellectually challenging and social activities was encouraged. I’m not sure which brain training program was used, but I’m enrolled in an ongoing study which used a computer-based program to assess changes in cognitive performance. It involves activities like memory retention by recalling patterns.
  • Nutrition: The MIND diet was prescribed, which emphasizes dark leafy greens, berries, nuts, whole grains, olive oil and fish, and limits sugar and unhealthy fats.
  • Health monitoring: Regular vital check-ins on blood pressure, weight, and lab work.

Engaging in regular exercise, performing mentally stimulating activities and eating healthy is a common-sense approach for overall good health. One important follow-up to the study will be to see if people can stick with the lifestyle changes once they are no longer part of the study’s structured program. Another analysis that I’d like to see is how many of the study participants go on to form Alzheimer’s or another form of dementia. Do the lifestyle changes prolong cognitive health thereby delaying a dementia diagnosis or do they offer further protective effects? An extension of the study has been funded and may answer some of these key questions.
