In the current study, graph theoretic analyses was applied to diffusion weighted data to explore the topological efficiency of structural networks in pediatric bipolar disorder (PBD). Significantly decreased small-worldness in PBD was observed, which may reflect decreased efficiency in information transfer, and may contribute to the affective and cognitive dysfunction in PBD.
