Summary

This preliminary study found that people with Type 2 diabetes who maintained moderate to high cardiovascular health based on the American Heart Association’s “Life’s Essential 8” were less likely to develop mild cognitive impairment or dementia, even if they had a high genetic risk. The results suggest that healthy lifestyle choices could help preserve brain health in those most at risk.

Key Takeaways

✅ Moderate to high cardiovascular health lowered dementia risk by 15% in people with Type 2 diabetes.
✅ Among those with high genetic risk, good cardiovascular health reduced dementia risk by up to 23%.
✅ Better heart health was also linked to greater brain volume, a sign of slower cognitive aging.
✅ The study used data from over 40,000 adults and found similar trends in both UK and U.S. populations.
✅ Lifestyle choices like diet, exercise, sleep, and blood pressure management may make a major difference.

Why It Matters for You

Even if dementia runs in your family, keeping your heart healthy by following Life’s Essential 8 can protect your brain. What’s good for your heart truly is good for your brain—especially for people managing Type 2 diabetes.
