Two-year LatAm-FINGERS results show structured lifestyle support improved thinking-test scores more than general health advice in Latin America. Lasting daily-function gains and actual dementia prevention are still being studied for people with mild cognitive impairment. Mild cognitive impairment means noticeable memory or thinking changes without loss of daily independence. The trial enrolled 1,065 adults ages 60-77 at higher dementia risk with low-normal scores, so many participants fit this early-risk profile.

Who took part in the study?
The study ran at 12 sites in 11 countries: Argentina, Bolivia, Brazil, Chile, Colombia, Costa Rica, Dominican Republic, Ecuador, Mexico, Peru and Uruguay. The Alzheimer's Association reports that investigators presented the two-year results on July 13, 2026 in London, with simultaneous publication in The Lancet Alzheimer's Association announcement. Eligibility focused on elevated risk plus suboptimal cognition, not dementia.
The NIH/PMC baseline analysis describes required elevated CAIDE risk scores and low-normal performance, including -1.5 to 0 z-scores on MMSE or CERAD word-list tests NIH baseline analysis. That design included people with mild impairment, including CDR 0.5. It excluded dementia, MMSE below 20 and illiteracy. Results therefore apply most directly to motivated older adults with early cognitive difficulty and vascular risk factors.
What did structured support add?
Both groups received attention to health habits. Controls received periodic health education and general lifestyle advice.
The structured group received a fuller, coached program with regular contact and social support. Core parts were: Coaching helped participants attend sessions, follow diet and exercise plans, and manage blood pressure and related risks. The contrast was therefore structured help versus advice alone, not treatment versus no care.
- supervised exercise
- dietary counseling
- cognitive training
- vascular-risk management
How much did thinking change?
Both groups improved on a global cognitive composite over two years. Medscape Medical News reports that the structured group improved 55% more than the general-advice group, a mean difference of 0.11 SD per year Medscape report. That is a test-score difference, not a cure.
It means sharper performance on memory and thinking measures after two years of steady support. Gains were largest in participants with lower starting cognition and less formal education. For families facing mild impairment with limited resources, guided structure may matter more than simple advice to stay active.
What is still being studied?
Daily function did not show the same clear edge. There was no significant between-group difference on Clinical Dementia Rating-Sum of Boxes, a scale of cognitive and daily function. The trial also did not prove fewer dementia cases. It tracked thinking-test change for two years, not later dementia diagnoses.
Longer work is examining durability of gains, biomarkers and real-world delivery. For now, readers can treat structured exercise, diet, thinking practice and vascular care as brain-health support, not guaranteed prevention. Practical next steps are concrete. Ask a clinician about blood pressure, diabetes, sleep, mood, hearing and medicines that affect thinking. Then seek guided programs for exercise, diet and cognitive training rather than general tips alone.
