A large-scale clinical trial demonstrates that daily lifestyle habits—particularly when guided through structured support—can improve and sustain cognitive function in older adults.
A new two-year study has found that everyday behaviors—such as physical activity, diet, cognitive engagement and social interaction—are directly linked to preserving brain health. Researchers enrolled over 2,100 older adults who were at risk of cognitive decline, then randomly assigned them to either a structured or a self-guided lifestyle intervention.
Both groups exhibited improved cognitive function over time, though the gains were more robust in the structured program, which provided greater support, accountability and measurable goals. The interventions included aerobic and strength exercises, adherence to the MIND diet, regular cognitive training and social interactions. “This study shows that non-pharmacological lifestyle changes can positively affect certain aspects of memory and thinking ability,” explained Dr. Jessica Langbaum.
The trial’s results held true across different ages, ethnicities, genetic risk profiles and cardiovascular health statuses. Researchers emphasize that even modest behavioral changes might meaningfully protect the brain, and further analysis will explore long-term effects and imaging or biomarker data.
