Abstract

Multiple Sclerosis (MS) is a disease usually associated with a working memory (WM) impairment. Study the efficacy of a WM cognitive training program in MS patients. 29 relapsing-remitting MS patients were enrolled in the study: 15 underwent WM training and 14 were assigned to a control group. All participants were neuropsychologically assessed and Functional Magnetic Resonance imaging (fMRI) images were acquired during 2 and 3-back execution (baseline and post-training +7days). Training improved MS patients’ performance in 2 and 3-back, hence showing shorter reaction times (RT) and higher percentages of correct responses (p<.001). During 2-back performance, non-trained MS-patients exhibited a greater activation in in right angular gyrus (FWEc=125, p<.001) that was correlated to RT (r=.459, p<.05). Further, lower activation in right precentral gyrus in the trained MS-patients (FWEc=273, p<.01) was also found. The results obtained demonstrates the effectiveness of a WM training program in MS-patients. Trained MS-patients showed a marked improvement of WM performance and increased cognitive efficiency, i.e, using less cerebral resources to achieve higher performance.
