In this study, we assessed functional connectivity (FC) at resting state (RS) within and among networks with potential functional relevance in 38 patients with pediatric multiple sclerosis (MS) and 18 age- and sex-matched healthy controls. Decreased FC was found in the sensorimotor and primary visual networks, as well as in posterior and infratentorial regions of the default mode, salience, executive control, attention and working memory networks. Conversely, increased FC was found in frontal regions of the salience and of the default mode networks. Decreased FC was associated with a more severe clinical disability and a longer disease duration.
