Exercise Program for Dementia Caregivers and Patients

The global cost of dementia is over 818 billion, and a further rise is expected in the next decade. While family caregiving is the backbone of the formal care service, promoting "living well with dementia" needs to extend to a dyadic perspective to address the needs of persons with dementia (PwD) and their caregivers. Unique to dementia caregiving, imbalanced exchange in the assistance, interaction, relationship and autonomy between the partners in a care dyad always challenges their social interaction and relationships. Such eroding dyadic dynamics not only worsens the mental health of caregivers, but also compromises the quality of caregiving, fosters more dementia deterioration, and eventually complicates the caregiving process. Nevertheless, least attention is directed to dyadic dynamics in promoting living well with dementia. Partner exercise is designed in a way which requires collaboration of two members to enable the workout of each other. In addition to the benefits of exercise on dementia symptom control and caregiver's stress management, partner exercise provides a meaningful encounter to encourage reciprocity, collaboration and relationship closeness within the care dyad. This is a sequential mixed-method study including a multicenter RCT to evaluate the effects of the 16-week enhanced BUDPA and a descriptive qualitative study to explore the care dyad's overall engagement experience and perceptions. The study will be conducted in 8 elderly community centres operated by four NGOs. The primary aim of the study investigates the effects of a 16-week enhanced BUDPA program on the health and dyadic dynamic of the persons with dementia and their family caregivers (Objective 1-3). The secondary aim explores dyads' overall experience in program engagement, particularly in terms of perceived benefits, challenges, and experience in self-directed practice (Objective 4). The primary outcomes include PwD's cognitive function and caregivers' mood status. We hypothesize that the 16-week enhanced BUDPA program will be more effective than usual care immediately post-test (T1: week 16) and 3 months (T2: week 29) and 6 months thereafter (T3: week 42) in: 1. improving cognitive function, NPS and HRQL of persons with mild to early-moderate dementia. 2. improving the affect, positive aspects of caregiving, and HRQL of family caregivers. 3. improving the dyadic dynamic between the person with dementia and family caregiver in a dyad.
