Michigan poll finds older adults underestimate lifestyle's role in preventing dementia

11% of Michigan residents over 65 have Alzheimer's or dementia, with families providing 680 million unpaid care hours annually.
People know brain health is important. They don't grasp how their own behavior shapes it.
A Michigan poll reveals a disconnect between what older adults believe matters and what they actually understand about dementia prevention.

In Michigan, a quiet contradiction has taken root among older adults: nearly all believe their brain health matters deeply, yet fewer than half understand that the daily rhythms of sleep, movement, and nourishment are the very levers that shape cognitive fate. A January 2026 poll of 1,293 residents aged fifty and older reveals not ignorance of the stakes, but a gap between valuing the destination and knowing the road. With one in nine Michiganders over sixty-five already living with Alzheimer's or dementia, and families absorbing hundreds of millions of hours of unpaid care, the distance between awareness and action carries a cost that is anything but abstract.

  • A striking paradox sits at the heart of the findings: 80% of older Michiganders call brain health very important, yet only 47% know that everyday choices can meaningfully reduce dementia risk.
  • The habits most linked to cognitive protection — daily exercise, balanced diet, adequate sleep, mental stimulation — are practiced consistently by only 36 to 54% of respondents, even among those who believe those habits matter.
  • Michigan trails the national average in brain health awareness, and residents in the Upper Peninsula and northern Lower Peninsula show even weaker understanding, suggesting deep regional inequities in health education.
  • Despite widespread openness to the conversation, only 23% of older Michiganders have ever discussed brain health with a doctor, and just 30% of those over 65 have received a cognitive screening in the past year.
  • Researchers and clinicians are calling for expanded public education and more proactive clinical dialogue, while also warning that a growing supplement market may exploit rising concern with false promises.

Walk into a Michigan doctor's office after fifty and you'll likely discuss cholesterol or blood pressure. What you probably won't discuss is your brain. A January 2026 poll of 1,293 adults aged fifty and older, conducted by the University of Michigan, reveals a troubling divide: nearly everyone cares about cognitive health, but fewer than half understand that their daily choices are the primary instrument of protection.

Eighty percent of respondents rated preventing head injury as very important to brain health. Seventy-one percent valued stress management and not smoking. Yet only 47% recognized that everyday lifestyle decisions — diet, sleep, exercise, mental engagement — could significantly lower dementia risk. The gap between valuing the outcome and understanding the mechanism is wide.

The behavioral picture is equally sobering. While 61 to 68% of respondents rated sleep, nutrition, mental stimulation, and physical activity as very important, only 36 to 54% actually practice these habits consistently. Michigan also lags behind national averages, with 70% of older residents connecting lifestyle to brain health compared to 76% elsewhere — a disparity that deepens in the state's more rural northern regions.

Healthcare providers are a missing link. Most older Michiganders say they'd welcome a conversation about brain health with their doctor, yet only 23% have ever had one. Poll director Jeffrey Kullgren, a primary care physician, noted that providers across the state could do far more to help patients understand how today's habits shape tomorrow's cognition.

The stakes are not abstract. Eleven percent of Michiganders over 65 live with Alzheimer's or another dementia, and their families provide over 680 million hours of unpaid care each year. No cure exists. Prevention and delay remain the most powerful tools available — which makes closing the gap between awareness and action not merely a public health goal, but a matter of profound human urgency. Researchers urge expanded education while cautioning that a growing market of brain-health supplements demands equal skepticism alongside genuine habit change.

Walk into a doctor's office in Michigan as someone over fifty, and you'll likely hear about your cholesterol, your blood pressure, maybe your weight. What you probably won't hear about is your brain. A new poll reveals a troubling gap: while nearly all older Michiganders say keeping their minds sharp matters deeply to them, fewer than half actually understand that the choices they make every day—what they eat, how much they sleep, whether they move their bodies—can meaningfully reduce their chances of developing dementia down the road.

The Michigan Poll on Healthy Aging, conducted by researchers at the University of Michigan, surveyed 1,293 adults aged fifty and older across the state in January 2026. The results paint a picture of awareness without understanding, concern without action. Eighty percent of respondents rated preventing head injury as very important to brain health. Seventy-one percent said managing stress and not smoking mattered. Yet when asked directly whether everyday lifestyle choices could significantly lower dementia risk, only 47 percent said yes. The disconnect is stark: people know brain health is important, but they don't grasp the mechanism by which their own behavior shapes it.

The gap widens when researchers looked at what people actually do. Fifty-four percent get seven or more hours of sleep most nights. Forty-eight percent engage in mentally stimulating activities regularly. Only 40 percent eat a balanced diet consistently, and just 36 percent get daily physical activity. These four habits—sleep, mental engagement, nutrition, and exercise—were rated as very important to brain health by 61 to 68 percent of all respondents. In other words, most people believe these things matter. Most people don't do them. The research backing this disconnect is unambiguous. Dementia risk is shaped by how we manage our cholesterol and weight, whether we address hearing loss, how much we drink, the quality of our sleep, the breadth of our social connections, and the vigor of our mental and physical lives. These are not peripheral concerns. They are the architecture of cognitive aging.

Michigan's numbers lag behind the national picture. Seventy percent of older Michiganders believe lifestyle factors are very important for brain health, compared with 76 percent of their peers in other states. Within Michigan itself, people in the Upper Peninsula and northern Lower Peninsula were even less likely to grasp the connection. The disparity suggests that education about brain health has not reached all communities equally, and that regional differences in health literacy or access to information persist.

The role of healthcare providers looms large in this story. Most older Michiganders said they would welcome conversations with their doctors about brain health. Yet only 23 percent have actually had such a discussion. Among those sixty-five and older, just 30 percent have undergone a cognitive screening test in the past year—a simple assessment that can catch early signs of decline. Jeffrey Kullgren, the poll's director and a primary care physician at the VA Ann Arbor Healthcare System, put it plainly: healthcare providers across Michigan and the nation could do far more to help patients understand how today's choices shape tomorrow's cognition. "Our state's adult population has high rates of risk factors for dementia," he said, "and we need to work together to address them at every age."

The stakes are concrete. According to the Alzheimer's Association's Michigan chapter, 11 percent of people over sixty-five in the state have Alzheimer's disease or another form of dementia. Their families and friends provide more than 680 million hours of unpaid care annually—a burden that falls disproportionately on women and that carries profound emotional and financial weight. While new medications have recently been approved to slow cognitive decline in early stages, and blood tests can now detect biomarkers of Alzheimer's disease, there is still no cure. Prevention, or at least delay, remains the most powerful tool available.

Scott Roberts, an associate director of the National Poll on Healthy Aging and professor at the University of Michigan School of Public Health, sees the path forward in expanded public education. The Alzheimer's Association's 10 Healthy Habits for Your Brain initiative offers a template. But Roberts also sounds a note of caution: as brain health becomes a more visible concern, the market for supplements and products claiming to preserve cognition will grow. Older adults need not just information about what works, but also skepticism about what sounds too good to be true. The conversation, in other words, must happen in two directions at once—toward the habits that matter, and away from the false promises that don't.

Healthcare providers across our state could do much more to help patients understand the link between the lifestyle choices they make today and their future brain health.

Why does it matter that people know lifestyle affects dementia risk if they're not changing their behavior anyway?

Model

Because knowledge is the prerequisite for change. Right now, many people think dementia is something that happens to them—bad luck, genetics, aging itself. If they understood that their daily choices shape their risk, they might make different ones. The poll shows they want to. They're just not being told.

Inventor

But the numbers suggest people aren't practicing these habits even when they say they're important. What's the barrier?

Model

It's not always knowledge. It's also access, habit, competing demands. A sixty-year-old working two jobs doesn't get eight hours of sleep because she doesn't value it—she gets five because that's what her life allows. The poll doesn't measure those constraints.

Inventor

So the real problem is that doctors aren't having these conversations?

Model

That's part of it. Only 23 percent of older Michiganders have discussed brain health with their provider. Most say they'd want to. The infrastructure for prevention doesn't exist yet in primary care.

Inventor

What about the regional differences—why would the Upper Peninsula know less about this?

Model

Could be information access, could be different health literacy, could be fewer specialists or less aggressive public health messaging in rural areas. The poll doesn't say. But it suggests that a statewide education campaign wouldn't reach everyone equally.

Inventor

Is there any good news in these numbers?

Model

Yes. People care. They recognize brain health matters. They're not dismissive or fatalistic. They're just uninformed about the mechanism. That's fixable. And the tools exist now—new medications, biomarker tests, simple cognitive screening. If we paired that with real conversations in doctor's offices, we could shift the needle.

Inventor

What worries you most about what the poll found?

Model

That we're in a window where prevention is still possible for millions of people, but we're not using it. In ten years, some of those people will have dementia that might have been delayed or prevented. And we'll have known what to do.
