Question 163 of 433
Is there proof that changing my lifestyle protects my thinking?
The short answer
Yes. Two large randomized trials have now shown it.
A Finnish trial called FINGER was the first. In 2025 an American trial, U.S. POINTER, confirmed it. More than 2,100 adults aged 60 to 79, all at higher risk of decline, followed a program of exercise, a brain-healthy diet, mental and social challenge, and monitoring of heart health for two years. Thinking and memory improved in both groups, and more in the group that received structured coaching and accountability.
Two details matter. The program combined several habits; no single one was the secret. And structure mattered. People did better with a schedule, a group, and someone checking in.
