A two-year lifestyle program has been shown to help older adults improve their memory, according to a landmark study. As individuals age, they often notice a decline in memory clarity—forgetting names, losing keys, or taking longer to grasp new concepts becomes more frequent. While some degree of change is normal, more severe issues can develop into dementia, which impacts memory, reasoning, and daily functioning.
Because there is currently no cure for Alzheimer’s disease and most other dementia forms, researchers have focused on finding ways to maintain brain health longer. A key question is whether healthy daily routines can slow down cognitive decline. Prior studies indicated that exercise, nutritious eating, mental exercises, and social connections might be beneficial, but most of this research was conducted in Europe or North America. Little attention had been paid to older adults in Latin America, despite the region’s rapidly growing elderly population.
To address this gap, the Latin American Initiative for Lifestyle Intervention to Prevent Cognitive Decline, known as the LatAm-FINGERS trial, was launched. Published in The Lancet, this study involved 1,065 adults between 60 and 77 years old from 11 Latin American countries. It was the first substantial brain health study tailored to the local culture, language, and lifestyle of this region.
Participants were randomly assigned to two groups. One group participated in a structured two-year lifestyle program. They engaged in supervised exercise sessions four times weekly, received personalized dietary guidance based on the MIND diet, performed computer-based brain training exercises, and regularly checked blood pressure, blood sugar, and weight. Additionally, they met in small groups to promote social activity. The program was adapted to fit local communities—exercise sessions included regional dances like salsa and tango, and meal plans focused on accessible, affordable foods.
The other group received only general health advice during four brief meetings over the course of the study.
The results favored the structured program, with participants showing approximately 55% greater improvement in memory and thinking skills each year compared to the control group. Memory showed the most notable gains, along with enhancements in planning and processing speed. These benefits were consistent regardless of age, educational background, ethnicity, or genetic risk factors for Alzheimer’s. Over 80% of participants completed the full program, and no significant health issues were linked to participation.
This trial was considered robust because it involved a diverse sample of over 1,000 older adults from multiple countries and lasted two years. It combined multiple healthy lifestyle interventions, giving a realistic picture of what individuals can incorporate into daily life.
However, the study focused on cognitive test improvements rather than actual dementia development, so longer-term follow-up is needed to see if these changes translate into reduced dementia risk.
The findings suggest that regular exercise, a nutritious diet, mental activities, social engagement, and proper management of health conditions could be key strategies for maintaining brain health with age. For those interested, recent research indicates that vitamin B9 deficiency may increase dementia risk, and cranberries might help improve memory.
Additional studies highlight that certain heartburn medications could raise the risk of dementia, while following the MIND diet appears to support cognitive function and potentially prevent dementia.
