Exercise and Brain Health: How Physical Activity Protects Cognitive Function, Even After Dementia Diagnosis

We all know exercise strengthens our bodies, but did you know it can also sustain life—even after a dementia diagnosis? Groundbreaking research from the British Journal of Sports Medicine reveals that staying active after a dementia diagnosis can reduce mortality risk by up to 29%.

But here’s the kicker: these findings aren’t just for those already living with dementia. They emphasize the lifelong benefits of physical activity, proving that movement is a powerful insurance policy for long-term health.

Key Findings: How Exercise Lowers Mortality Risk

The study followed over 60,000 individuals diagnosed with dementia, tracking their physical activity habits before and after diagnosis. Here’s what the research uncovered:

• Consistent exercise reduces risk: Participants who stayed active before and after diagnosis had a 29% lower risk of death compared to those who were inactive.

• It’s never too late to start: Even people who began exercising after their diagnosis saw a 20% reduction in mortality risk.

• All movement counts: Light activities like walking were just as beneficial as moderate or vigorous workouts.

These results highlight a powerful truth: exercise is beneficial at any age or fitness level, offering hope and tangible health benefits even in the face of cognitive decline.

Why This Matters for You

If you’re young and healthy, dementia might seem like a distant concern. But this study is a crucial reminder: staying active today can protect your brain and body decades from now.

With dementia rates rising globally, many of us will care for—or know someone living with—cognitive decline. The takeaway? Movement is medicine, even for progressive illnesses like dementia.

What Counts as Exercise?

The good news? You don’t need intense workouts to reap the benefits. Here are simple, effective ways to incorporate movement into your daily routine:

• Walk-and-talk meetings: Swap the conference room for a walking discussion.

• Dance breaks: Crank up your favorite song and move for 5 minutes.

• Exercise snacks: Do squats, stretches, or lunges between tasks.

• Weekend nature hikes: Get outside for fresh air and mental clarity.

Supporting Loved Ones with Dementia

If someone you care for has dementia, gentle physical activities can make a big difference. Consider:

• Group walks for social interaction and light exercise.

• Stretching routines or chair yoga to improve mobility and relaxation.

Remember, physical activity doesn’t have to be intense to be impactful. Even small, consistent efforts can improve quality of life and longevity.
