There are a number of things that can influence how we think as people age, including diabetes, depression, as well as our biology. In this study, the investigators are using PET scans with a tracer to create detailed pictures of the brain. This information will be used to help the investigators understand how the brain ages and in the future could be used to develop better diagnostics and treatments for Alzheimer's disease and memory loss in Mexican Americans, African Americans, and non-Hispanic whites. The goal of this study is to address this disparity by enrolling ethnically diverse participants in this study.
