Study population
The study population is community-dwelling older adults with mild-to-moderate AD. The inclusion and exclusion criteria for the study sample are detailed in Table 1. Mild-to-moderate AD will be defined as Clinical Demen- tia Rating (CDR) scores of 0.5 to 2 and Mini-Mental State Examination (MMSE) scores of 15 to 26. We will pro- actively recruit minorities using recommended strategies, such as providing educational seminars and hiring ethnic- ally diverse staff.
