Huntington disease (HD) is associated with a variety of cognitive deficits, with prominent difficulties in working memory (WM). WM deficits are notably compromised in early-onset and prodromal HD patients. This study aimed to determine the feasibility of a computer-ized WM training program (Cogmed QM), novel to the HD population. Nine patients, aged 26-62, with early stage HD underwent a 25-session (5 days/week for 5 weeks) WM training program (Cogmed QM). Training exercises involved the manipulation and storage of verbal and visuospatial information, with difficulty adapted as a function of individual performance. Neuropsychological testing was conducted before and after training, and performance on criterion WM measures (Digit Span and Spatial Span) and near-transfer WM measures (Symbol Span and Auditory WM) were evaluated. Post-training inter-views about patient experience were thematically analyzed using NVivo software. Seven of nine patients demonstrated adherence to the training and completed all sessions within the recommended timeframe of 5 weeks. All adherent patients reported that they found training helpful (n=7), and almost all felt that their memory improved (n=6). Compared to baseline scores, patients showed significant improvement on the neuropsychological measures of verbal WM, including Digit Span (p = .047) and Auditory WM (p = .041). This pilot study provides support for feasibility of computerized WM training in early-stage patients with HD. Results suggest that HD patients can improve WM with intensive training, though a full-scale intervention project is needed to understand the reliability of changes over time.
