Summary

This study tested three non-drug approaches—cognitive training, reminiscence therapy, and a personalized program—in 640 people with mild-to-moderate Alzheimer's. The goal was to see if these therapies could delay progression to severe dementia. Participants were followed for changes in thinking, daily function, mood, and quality of life.
