What Is This Study About?
The purpose of this study is to see if lifestyle changes, such as exercise, diet, and cognitively stimulating activities, can protect memory and thinking in older adults who are at an increased risk of significant memory loss. In this two-year study, people will be randomly assigned to participate in one of two lifestyle modification programs. Researchers will compare results of people who are given the education, support, and tools to develop and carry out healthier lifestyle practices with people who are assigned to a structured program of diet, physical and cognitive exercise, and management of cardiometabolic risks.
