Alterations in connectivity in children with left and right cerebral palsy compared to typically developing children were assessed. Connections with altered FA or MD were identified automatically from the connectome. Only pathways within the ipsilesional hemisphere, and interhemispheric pathways showed reductions in FA and increases in MD compared to typically developing children. In both children with left and right hemiplegia, connections between the motor regions and the brain stem, the thalamus, cerebellum and posterior cingulate were altered, as well as fronto-parietal connections and the interhemispheric motor pathway.
