A two-year randomized trial across 11 Latin American countries found that older adults at risk of dementia gained more cognitive benefit from a structured, coach-led lifestyle program than from a flexible self-guided version of the same approach. A structured, coach-led lifestyle program against a flexible self-guided version, over two years, in 1,065 older adults aged 60 to 77 at risk of cognitive decline. What did the structured program include? Where can I find a structured program? YMCAs, senior centers, Area Agencies on Aging, cardiac rehabilitation, and diabetes self-management education programs offer supervised group options.
