Dementia incidence is rising, posing a public health challenge, but 45% of cases can be prevented by addressing modifiable risk factors. Multidomain trials show that lifestyle changes can improve cognitive function and reduce dementia risk (like the FINGER trial). The REMINDER program, a Portuguese-based dementia risk reduction protocol, was developed for community-dwelling older adults aged 55 and above. However, older adults in Residential and Daycare Facilities (RDF) have distinct needs that demand program adaptation to ensure its relevance and effectiveness. In addition, more studies are needed to evaluate the impact of multidomain interventions with older adults in RDF. To address these challenges, the REMINDER4Care program was developed as a tailored, multidomain intervention to reduce dementia risk. It emphasizes social and cognitive engagement and advances its adaptation and evaluation in Residential and Daycare Facilities (RDF). To assess efficacy, the investigators will perform a Randomized Controlled Trial.
