Summary

This study tests whether a program of group nutrition classes, physical activities like walking and gardening, and at-home cognitive training can help prevent cognitive decline in older adults at higher risk for dementia. Researchers will enroll 120 people aged 55-85 and track changes in diet, quality of life, and memory complaints over the course of the intervention.
