LatAm-FINGERS found that older adults who got structured, ongoing lifestyle coaching improved their cognition more than those who were simply handed a lifestyle plan and left to follow it themselves. The trial enrolled people at elevated dementia risk, including many with measurable but mild cognitive decline, and tracked them for two years across 11 Latin American countries. The study, part of the Alzheimer's Association-funded World-Wide FINGERS network, was presented at the Alzheimer's Association International Conference (AAIC) in London and published simultaneously in The Lancet on July 13, 2026. For readers managing mild cognitive impairment (MCI) or watching for early decline in a parent or spouse, the result adds a second large trial to evidence that coaching and structure, not just knowing the right habits, is what moves cognitive test scores.

What LatAm-FINGERS actually tested
LatAm-FINGERS was a two-year, single-blind randomized controlled trial of 1,065 adults aged 60 to 77, run across 12 study centers in 11 Latin American countries, according to the Alzheimer's Association. Every participant followed a multidomain lifestyle program covering diet, exercise, cognitive activity, and social engagement, but the trial split them into two groups to test *how* that program was delivered. One group, the structured lifestyle intervention (SLI) arm, received ongoing coaching sessions and peer support throughout the two years.
The comparison group, the self-guided or "FLI" arm, got the same lifestyle recommendations but met with the study team only four times over the full two years, with no ongoing coaching, as described by Alzheimer-Europe. That design isolates the effect of coaching and accountability from the effect of the lifestyle advice itself. The trial also had unusually strong follow-through: 82% of enrolled participants completed the full two-year assessment schedule, according to Alzheimer-Europe. That retention rate matters because a trial that loses most of its participants to dropout can't reliably show whether an effect lasts.
Who was eligible, and why that matters for MCI
A notable detail for readers with an MCI diagnosis: LatAm-FINGERS did not require one. Eligibility instead required a CAIDE dementia-risk score above 6, plus cognitive test results suggesting risk — an MMSE z-score between 0 and -1.5, or below-average scores on CERAD word-list or delayed-recall tests, according to the trial's listing on ClinicalTrials.gov.
People with an MMSE score under 20, or an existing dementia diagnosis, were excluded. In practice, that means the trial population overlaps heavily with people who have mild, measurable cognitive decline but may not carry a formal MCI diagnosis on paper. If you or a family member has been told your cognitive testing shows "mild" changes, or you score in a risk category on a dementia-risk screening tool, you fall into the range of people this trial was designed around — whether or not a clinician has used the term "MCI.".
How much of a difference did coaching make?
The SLI group showed 55% greater improvement on a composite measure of global cognition than the self-guided comparison group, according to Healio's coverage of the AAIC presentation. That composite score blends several cognitive domains into one number, which is standard practice in dementia-prevention trials because it smooths out noise from any single test.
Beyond the composite score, the coached group also showed significantly larger gains specifically in memory, executive function (planning and decision-making skills), and processing speed, compared with the self-guided group, per Alzheimer-Europe. These are the same domains that tend to decline first and most noticeably in early cognitive impairment, which is part of why the result is relevant to an MCI-focused audience rather than only to dementia-prevention research in general.
How this fits with the earlier U.S. POINTER trial
LatAm-FINGERS is described as reinforcing and extending the 2025 U.S. POINTER trial, published in JAMA, which found that a structured multidomain lifestyle program improved a global cognitive composite by 0.029 standard deviations per year more than a self-guided version (95% CI 0.008-0.050; P=.008), according to JAMA's summary of U.S. POINTER.
That earlier trial ran in the United States with a different population. The two trials together give a consistent signal across different countries, cultures, and healthcare systems: giving someone a lifestyle plan and giving someone a lifestyle plan plus ongoing coaching and peer accountability do not produce the same cognitive outcome. The practical implication researchers drew, per the Alzheimer's Association, is that structured coaching and peer support produce larger cognitive benefits for older adults at elevated dementia risk than simply handing them recommendations to follow alone.
What the trial does not show
LatAm-FINGERS measured changes in cognitive test scores over two years — it did not track whether participants went on to be diagnosed with dementia, according to Alzheimer-Europe. That distinction matters for anyone trying to translate these results into a personal decision: the trial shows that structured coaching produced measurably better cognitive test performance than self-guided lifestyle change, but it does not show that the program prevented dementia or reversed an existing MCI diagnosis.
For a reader considering next steps, that limitation points toward a specific, practical takeaway rather than a sweeping one. The best-supported action from this trial is seeking out structured, ongoing support — a coached program, a group-based lifestyle intervention, or regular check-ins with a clinician or health coach — rather than relying solely on a one-time list of recommendations for diet, exercise, and cognitive activity. People considering this path should ask:.
- Does the program include ongoing coaching sessions, not just an initial consultation?
- Is there a peer or group component, which the SLI arm included alongside individual coaching?
- Does it address the same domains tested here — diet, physical activity, cognitive engagement, and social connection — together, rather than one at a time?
- Is there a clear schedule of follow-up over months or years, rather than a single session?
