Dementia and mild cognitive impairment (MCI) deeply impact individuals' well-being and are expected to increase due to population aging, with global cases projected to rise to 152.8 million by 2050. Social isolation, accounting for 4% of dementia cases, emerges as a critical modifiable risk factor, particularly in institutionalized older adults, where it significantly raises dementia risk.
To address these challenges, the REMINDER program was developed as a tailored, multidomain intervention to reduce dementia risk, emphasizing social and cognitive engagement and advancing its adaptation and evaluation in Residential and Daycare Facilities (RDF). To assess the feasibility of REMINDER in older adults supported by RDF (recruitment, adherence, retention, acceptability, accessibility, and usability) and explore potential changes in cognitive and psychosocial outcomes.
Implementing DRR programs in RDFs presents several unique challenges, including participant diversity in educational levels, physical and cognitive health, motivation, and logistical constraints within institutional settings. A feasibility study is essential to identify and determine how to overcome these barriers. Specifically, this study explores acceptability, accessibility, adherence, and usability to optimize the REMINDER intervention for RDF settings. By addressing these practical concerns, the feasibility trial will ensure the intervention is effective and implementable, laying the groundwork for a successful full-scale RCT that meets the needs of older adults in RDFs (resulting in an adapted version, the REMINDER4Care). By creating an engaging and well-accepted tool, we look forward to amplifying the RDF tools available to reduce the risk of dementia in their residents.
Objectives
The primary objectives of this study were as follows:
Secondary objectives included exploring preliminary changes in cognitive and psychosocial outcomes from baseline to post-intervention while acknowledging that the study was not powered to detect statistically significant effects.

|---|---|---|---|
| REMINDER intervention | Experimental | The REMINDER intervention includes 20 face-to-face group sessions, each approximately 60 to 75 minutes, held twice a week over ten weeks. This program aims to optimize memory, attention, executive function, and emotional regulation while promoting lifestyle habits that protect the aging brain. The sessions include brain health education, cognitive exercises, compensatory memory strategies, training for managing personally relevant goals (with goal setting), and stress management techniques (compassion-based therapies, relaxation methods, and mindfulness). As for the structure of the sessions, each starts with a mindfulness exercise and concludes with a review of the homework assignments. Every session includes a psychoeducation component focused on a specific topic, a time for sharing and reflection, and a practical activity. |
