LatAm-FINGERS, a two-year trial of 1,065 older adults across 11 Latin American countries, found that structured, coach-supervised lifestyle changes improved thinking skills about 55% more than a lighter, self-directed version of the same program (Alzheimer's Association, AAIC 2026). For people with mild cognitive impairment, or MCI — the stage between normal aging and dementia where memory or thinking problems are noticeable but daily life is still manageable — the update confirms that how a lifestyle program is delivered matters as much as what it includes. The trial was the first randomized test of a multidomain lifestyle intervention for dementia prevention run specifically in Latin America, enrolling adults aged 60 to 77 at elevated dementia risk across 12 study centers (Alzheimer's Association, AAIC 2026 press release). Results were presented at the Alzheimer's Association International Conference in London and published simultaneously in The Lancet on July 13, 2026 (Alzheimer's Association / The Lancet).

What the trial actually tested
Researchers split participants into two groups. The first received a structured lifestyle intervention (SLI): supervised exercise sessions, counseling on the MIND diet, computerized cognitive training, management of cardiovascular risk factors, and group social sessions with ongoing coaching throughout the two years (Alzheimer Europe). The second group, the self-guided or flexible lifestyle intervention (FLI), received only four group meetings covering the same topics — diet, physical activity, cognitive and social engagement, and vascular risk — with no ongoing coaching or supervision after that. Both groups improved their cognition over two years, which is itself notable.
But the SLI group improved about 55% more on a composite measure of global cognition than the FLI group (Alzheimer's Association, AAIC 2026). That comparison is the core finding: coaching and supervision, not just information, drove the extra benefit. Within the SLI group, episodic memory — the ability to recall specific personal experiences and events — showed the largest gain. Executive function and processing speed also improved significantly more than in the FLI group (Alzheimer's Association, AAIC 2026).
Why this matters for people with mild cognitive impairment
The trial didn't require a confirmed MCI diagnosis to enroll. Eligibility was based on an elevated cardiovascular-dementia risk score (CAIDE above 6) combined with early signs on standard cognitive tests — either a specific memory-test score below a threshold or a general cognitive screening score in a defined at-risk range (ClinicalTrials.gov registry NCT06492967). That means the study population includes many people who would be considered at high risk for MCI or in its early stages, even though it wasn't restricted to those with a formal MCI diagnosis.
For readers managing an MCI diagnosis or caring for someone with one, the practical takeaway lines up with an earlier U.S. trial: a structured, supervised, multidomain program outperforms a lighter, self-directed version for people at risk of cognitive decline, including those in the MCI risk range (Alzheimer's Association, AAIC 2026). That earlier trial, U.S. POINTER, tested a similar SLI-versus-FLI design in the United States and reached the same conclusion — LatAm-FINGERS now extends that finding to a different population, diet, and healthcare setting.
Was the program adapted for Latin America, or copied from elsewhere?
The protocol was not a direct translation of the U.S. POINTER or Finnish FINGER trials. Researchers adapted the lifestyle intervention to local diets, habits, and healthcare resources across the 11 participating countries, as part of the broader World-Wide FINGERS research network (Alzheimer's Association, AAIC 2026 press release).
This adaptation matters because dietary counseling, exercise access, and healthcare infrastructure vary widely across the region. A program built around ingredients, foods, and clinical resources available in Helsinki or Chicago would not transfer cleanly to a trial spanning a dozen centers across Latin America. The adapted design is part of why the result is being treated as evidence specific to the region, not just a replication exercise.
How safe and how feasible was the program?
Two markers support the practicality of a structured program like this one. First, 82% of enrolled participants completed the full two-year follow-up — a high completion rate for a multidomain lifestyle study that asks people to sustain exercise, diet changes, cognitive training, and social sessions over two years (Alzheimer Europe).
Second, researchers reported no serious adverse events or deaths attributable to either intervention. Together, these findings suggest a coached multidomain program is both safe and sustainable for older adults at elevated dementia risk, not just effective on paper. That combination — strong adherence plus no safety signal — is part of what makes the coaching-versus-self-guided comparison meaningful rather than a result that only held up for a small subset of highly motivated participants.
What this means for choosing a program
Readers evaluating a lifestyle program for themselves or a family member with MCI or elevated dementia risk can use the SLI-versus-FLI distinction as a practical checklist: The LatAm-FINGERS result does not suggest that self-guided information is worthless — the FLI group improved too. It indicates that for people already at elevated risk, the added structure and supervision of ongoing coaching produced a substantially larger cognitive benefit over two years than information alone.
- Does the program include ongoing, supervised coaching sessions, or only a handful of one-time informational meetings?
- Does it combine multiple domains at once — exercise, diet, cognitive training, vascular risk management, and social engagement — rather than addressing just one?
- Is there a mechanism for regular check-ins and adjustment over months, not just an initial consultation?
