1. Recruitment. Study participants will be recruited from local caregiver support groups of Kaiser Permanente in Oakland. Exercise instructors and the PI have already been invited to give presentations at their regular meetings. Contacts have been established with 3 caregiver support groups meeting at Kaiser Permanente in Oakland, totaling about 100 caregivers, who meet once a month and confirmed strong interest to participate. Thus, it is highly likely that we will twice be able to recruit 10 dyads of eligible participants. In addition, investigators will give study flyers to caregiver support managers at Kaiser Permanente, the local Alzheimer's Association groups, and the Alzheimer's Services of the East Bay (ASEB). In addition, we will recruit at ASEB.
