A Non-Randomized Pilot Trial of Brain-WISE: A Group-Based Program for Brain Health and Dementia Risk Reduction in Community Settings.

Abstract

BackgroundAddressing modifiable risk factors can potentially prevent 45% of cases of dementia. Here, we present the development of Brain-WISE, a low-intensity, group-based intervention to improve brain health in community settings. We conducted preliminary testing to refine intervention materials and procedures, assess acceptability and adherence, and evaluate preliminary effects.Methods143 community-dwelling adults aged 56-93 completed the non-randomized pilot trial. The 6-session intervention included psychoeducation, discussion/activities, and health screenings. Adherence was measured by attendance and acceptability was measured with questionnaires. Brain health knowledge and motivation to improve brain health were assessed before and after the program.ResultsAcross 6 cohorts, attendance was 80% - 97% and 96% of participants agreed that the program was worthwhile. Knowledge (d = 0.83, P < .001) and motivation (d = 0.43, P < .001) increased significantly.ConclusionsThe Brain-WISE program displayed good adherence and acceptability and evidence of an effect on knowledge and motivation. Further testing is warranted.
