Participants in the control group will have 10-minute phone calls with study staff weekly to monitor their social activities and health conditions. Investigators will complete in-home testing to measure memory and executive function. Participants at Oregon Health & Science University will also have their medication compliance tracked using electronic pillbox devices.
