P115: Testing the feasibility of a multicomponent neuropsychological intervention for individuals at-risk of dementia: the REMINDER program

Abstract

Objective:

Interventions aimed to optimize cognitive function and functionality in individuals at risk of dementia were scarce in validity studies. While some RCTs have been developed in cognitive training interventions, studies of multicomponent interventions (cognitive, social, and behavioral) integrating intervention targeting psychosocial risk factors (social isolation, depression, low cognitive reserve) is absent. Additionally, few efforts have been made to develop such validity studies with individuals at higher risk of dementia who still do not present objective cognitive decline, despite current recommendations in this regard. We aimed to start the validation of a 20-session multicomponent intervention – REMINDER program - with a feasibility test and a preliminary efficacy testing using a comprehensive outcome assessment protocol.

Methods:

A feasibility randomized controlled trial (RCT) was conducted, recruiting community-dwelling individuals between 60 to 75 years old with increased risk of dementia (LIBRA dementia risk score). Fifteen participants took part in twice-a-week sessions of the REMINDER program, during twelve weeks. Data on the acceptability, satisfaction and adherence to the REMINDER program was collected, and an association between pre and post intervention motivation and knowledge about dementia risk was examined. For the preliminary efficacy testing we considered as primary outcome a performance-based functionality measure (UPSA) and secondary outcomes will include global cognition, emotional status, and lifestyle habits, tested prior and after the intervention.

Results:

Rates of satisfaction throughout the REMINDER program sessions were high (75%, mean) as well as the adherences that was superior to the main dementia risk reduction programs referred in literature. (83%). Post-intervention efficacy testing is ongoing, however, levels of knowledge about dementia risk increased 12% compared with pre-intervention (34% pre-intervention, to 46% post intervention; p=.045)

Discussion:

Preliminary data on feasibility and efficacy of the REMINDER program suggests this program is an engaging and motivating tool for dementia risk reduction, justifying the future implementation of a large-scale RCT. We expect that, with a larger efficacy study we can demonstrate the REMINDER program effects in behavior change and in the adoption of protective lifestyles for dementia prevention, and that the comprehensive outcome assessment proves to be effective and, therefore, replicable in further studies.
