FINGER — Finnish Geriatric Intervention Study to Prevent Cognitive Impairment
In plain English
FINGER randomised 1,260 at-risk older Finns to a multi-domain intervention (diet, exercise, cognitive training, vascular risk management) or general health advice. After two years, the intervention group preserved cognition significantly better — the first large RCT to show cognitive decline can be slowed by lifestyle alone.
Why it matters
Diet + exercise + cognitive training preserved cognition in at-risk adults.

Caveats
Multifactorial intervention — the contribution of diet alone cannot be isolated. Effect size on cognition is statistically significant but clinically modest over two years.
