A lifestyle program helped protect memory across Latin America
A major trial found that a structured, coached program of exercise, nutrition and social activity improved older adults' cognition 55% more than general lifestyle advice alone.
Doctors have long known that exercise, good nutrition and staying socially engaged are good for the aging brain. A large new clinical trial has now shown just how much of a difference a structured version of that advice can make, and across an entire continent.
The LatAm-FINGERS study followed 1,065 older adults at risk of cognitive decline across 12 sites in 11 Latin American countries, including Argentina, Brazil, Mexico, Colombia and Chile. Half received a structured, coached program combining physical activity, nutrition guidance, cognitive and social activities and health monitoring; the other half received general lifestyle advice on their own.
Over two years, participants in the structured program showed 55% greater improvement in overall cognitive function than those given general advice alone, with notably better memory, executive function and processing speed. The benefits held up regardless of participants' sex, ethnicity or genetic risk for Alzheimer's.
Funded by the Alzheimer's Association and presented at its 2026 International Conference, the findings suggest that with the right structure and support, protecting the brain as it ages may be more achievable than many people realize.
