Working Memory Training for People Aging with HIV

The present study investigates the feasibility of working memory training in people aging with HIV (PAWHIV). In a cross-over design this stage 1 feasibility trial, will evaluate acceptability, and estimate possible effect sizes related to working memory training by examining potential differential effects in PAWHIV and those aging without HIV. This project highlights the importance of tailored cognitive assessments and interventions, engaging with underrepresented communities to enhance inclusivity in cognitive health research.

In a randomized controlled trial (RCT) with a 3x2 design (pre-test, post-test, follow-up; PAWHIV, people aging without HIV), we will evaluate feasibility of implementing working memory-based interventions in PAWHIV. This study will examine the differential effects of WM training between PAWHIV and aging adults without HIV, providing insight into specific cognitive challenges in PAWHIV that may influence the efficacy of cognitive training interventions. The results of this trial will be instrumental in developing targeted, evidence-based interventions that promote cognitive health for PAWHIV and contribute to the broader understanding of cognitive aging in vulnerable populations. Relying on an extended battery of cognitive assessments, we will test different multivariate models to best capture the unique cognitive profiles of PAWHIV and how they compare with people aging without HIV. This analytical framework will allow us to gain insight into and better addressing the needs of the PAWHIV community The cross-over trial will obtain within-subject comparisons of training with enriched (game-like) versions of working memory training tasks compared to basic (non-gamified) versions of these tasks. Participants are assigned to Non-Gamified Span training and Gamified Span training for a total of 50 sessions per participant: the first few sessions consist of completing questionnaires and computerized cognitive assessments (pre-test). Participants then complete 20 sessions of working memory training. After a mid-test, they complete 20 sessions of a different type of working memory training. Post-test is administered upon training completion, and at least a month later, participants complete 3 follow-up sessions.
