Summary
This major review by the National Academies assessed scientific evidence on strategies to prevent cognitive decline and dementia. Although no single intervention had enough proof to justify a major public health campaign, three strategies—cognitive training, managing high blood pressure, and increasing physical activity—were found to have “encouraging but inconclusive” evidence. The study emphasizes the need for better-designed research to clarify what really helps preserve brain health as we age.

Key Takeaways
✅ Cognitive training (like memory or reasoning exercises) may help delay normal age-related cognitive decline.
✅ Managing high blood pressure in midlife could help prevent dementia later on.
✅ Regular physical activity shows promise in slowing cognitive aging.
✅ Stronger evidence is still needed before making official public health recommendations.
✅ Future research should include diverse populations, start interventions earlier, and use better, consistent measurements.

Why It Matters for You
Simple lifestyle changes—like staying physically active, engaging your brain, and keeping your blood pressure in check—might protect your memory and thinking skills as you age. While the science isn’t yet conclusive, these actions benefit your overall health and could support long-term brain health too.
