PREVENTING DEMENTIA: LIFESTYLE WORKS

Dementia is one of the most feared diagnoses, not just because of what it takes from individuals, but because of how deeply it affects families, caregivers, and communities. Even if we haven’t personally seen a loved one go through it, we all feel its weight. This is why prevention matters.

Dementia is often thought of as something that only affects the very old. But it can begin earlier, sometimes in people in their 40s or 50s. While age is the biggest risk factor, lifestyle choices at any stage of life can make a real difference in protecting our brains. That’s why prevention matters now, not later.

What the US POINTER Trial Taught Us

The US POINTER Randomized Clinical Trial published in JAMA gives hope. In this randomized trial of 2,111 older adults at risk for dementia and cognitive decline, researchers tested two approaches:

A structured lifestyle intervention (n = 1,056) that included:

• Regular moderate- to high-intensity exercise

• The MIND diet (designed to support brain health)

• Cognitive challenges

• Social engagement

• Cardiovascular health monitoring

And a self-guided approach (n = 1,055) using educational materials and less intensive support.

After 2 years, both groups benefited, but those in the structured group showed a 𝘀𝘁𝗮𝘁𝗶𝘀𝘁𝗶𝗰𝗮𝗹𝗹𝘆 𝘀𝗶𝗴𝗻𝗶𝗳𝗶𝗰𝗮𝗻𝘁 𝗴𝗿𝗲𝗮𝘁𝗲𝗿 𝗶𝗺𝗽𝗿𝗼𝘃𝗲𝗺𝗲𝗻𝘁 𝗶𝗻 𝗴𝗹𝗼𝗯𝗮𝗹 𝗰𝗼𝗴𝗻𝗶𝘁𝗶𝗼𝗻 than the self-guided group. (study link)

Why It Matters

According to Alzheimer's Disease International, in 2020, more than 55 million people around the world were living with dementia. By 2030, that number is expected to rise to 78 million. By 2050, that number could nearly triple (139 million). Behind each number is a person, a family, a story.

Dementia doesn’t only change the later years of life, it can reshape whole families for decades. Prevention is not about avoiding aging; it’s about protecting memory, connection, and independence for as long as possible.

The trial shows something powerful: even without new drugs, we already have tools that can protect our brains.

From Knowing to Living

We’ve all heard the advice before: eat well, move your body, stay social, challenge your brain. The harder part is making those choices every day, especially when life feels too busy, stressful, or lonely. That’s where support makes the difference.

DIGITAL TOOLS THAT HELP

As someone who has been working in the digital health space since 2017, I’ve seen how essential it is to bridge evidence-based prevention with real-world accessibility. Studies like this one underscore the massive potential of preventive care, especially when it’s personalized, supported, and sustained. Digital health and health tech solutions have enormous potential to scale these kinds of interventions, making them more accessible, affordable, and tailored to individual needs.

Some promising innovative solutions already support people at risk of dementia:

• BrainTrack (Dementia Australia): Helps people monitor cognition and build healthy brain habits.

• Brain+: pioneers of digital Cognitive Stimulation Therapy (CST), the world’s leading non-drug dementia treatment.

• CognICA: an FDA-approved tool to gauge cognition, or higher-level functioning.

• Tovertafel (“Magic Table”): Interactive games that bring joy, movement, and stimulation.

• Cognitive Evergreenland app: Engages people at risk through behavior-change science.

They don’t replace people or care but they can make prevention easier, more consistent, and even more fun.

Everyday Choices

You don’t need an app to start. Here are small, proven steps that matter:

• A daily walk or dance in the living room

• Filling your plate with greens, beans, nuts, and berries

• Learning something new a language, an instrument, even a puzzle game

• Making time for sleep and quiet moments

• Staying connected through phone calls, coffee with a friend, joining a group

• Caring for your heart because what’s good for the heart is good for the brain

These small steps may not seem dramatic, but over time, they add up. Each choice is a quiet investment in our future selves and a gift to the people who love us.

As you can see, this isn’t just about data or studies. 🌍 It matters globally. We’re not talking about isolated cases, but millions of people are already affected, and that number is still rising. The cost is counted in billions, but the true weight is in the human stories. This is a public health crisis.

At its heart, it’s about everyday life: holding onto names, stories, independence, and the small moments that make us who we are. Prevention is never perfect, but it gives us a fighting chance to keep more of ourselves, for longer.

The study shows that nonpharmacological, accessible, and relatively low-cost lifestyle interventions can work. They can slow decline, protect cognition, and potentially reduce future dementia cases.

So this isn’t just about science it’s about dignity, independence, and quality of life. For all of us. ♥
