People with mild cognitive impairment — noticeable memory or thinking changes that do not yet block daily life — can build a realistic brain-health plan around coached exercise, healthy eating, brain training and social contact. In 2026, the LatAm-FINGERS trial found structured coaching improved overall memory, thinking and reasoning 55% more than self-guided advice. LatAm-FINGERS was a 2-year, single-blind, multicenter randomized trial of multidomain lifestyle intervention, as reported by the Alzheimer's Association in its AAIC 2026 announcement. It enrolled 1,065 adults ages 60-77 at elevated dementia risk at 12 sites in 11 countries across Latin America.

What did the coached program include?
Coached participants followed a weekly routine with clear targets and supervision. According to Welltica reporting on the Lancet and AAIC findings, the routine combined supervised aerobic exercise, strength work, diet counseling, brain training and health checks in its summary of the four lifestyle changes.
The exercise target was about 30-35 minutes of aerobic activity four times per week, plus strength and flexibility twice weekly. Diet work used personalized MIND-diet counseling adapted to local foods and habits. Other parts included computerized cognitive training, cardiovascular-risk monitoring and regular group or social sessions.
Why did coaching beat advice alone?
Participants were randomized to structured coaching with supervision or self-guided health advice without ongoing coaching. That design tested whether intensity and support change outcomes, not just information.
The coached group gained 0.029 standard deviations per year extra on global cognition, with the largest gain in executive function, according to the AAIC 2026 overview in its trial overview. Executive function covers planning, focus, switching tasks and self-control. Enrollees averaged 67.5 years, were mostly women, and largely identified as mestizo, Indigenous, mulatto or mixed, which suggests culturally adapted delivery can work across varied settings.
Can people with MCI use these results?
Yes, as a planning model, with one key limit. The trial enrolled at-risk older adults with suboptimal test performance, not people diagnosed specifically with mild cognitive impairment, and it measured change on cognitive tests over two years rather than prevented dementia cases, according to the UT Health San Antonio School of Public Health in its analysis of the structured program. That matters for expectations.
The result supports slower decline and better test scores with support, not a cure or guaranteed prevention. People with mild cognitive impairment often share the same risk factors studied here, such as low activity, poor diet, vascular risk and isolation. A reader with mild cognitive impairment should review medications, heart risk, mood, sleep and safety with a clinician before copying the exercise or diet targets.
How to build a realistic weekly plan?
Copy the structure, not just the topics. Ask a clinician, coach, dietitian or community program for scheduled check-ins and peer contact. Bring your medicine list and recent blood pressure readings to that first planning visit.
- Move four days: brisk walking, cycling or dancing for 30-35 minutes, plus two short strength and stretch sessions.
- Eat MIND-style: leafy greens, beans, whole grains, fish, nuts, olive oil and berries when available, with less fried food, sweets and processed meat.
- Train thinking three to five times weekly: a structured brain-training app, class or workbook, not passive puzzles alone.
- Meet weekly: a walking group, class, faith group or support group for accountability.
- Track vascular risk: blood pressure, blood sugar, cholesterol, smoking and prescribed medicines, with regular follow-up.
