Network analysis method was used to investigate the architecture of the white matter structural networks bipolar disorder. Although bipolar patients showed a small-world organization of white matter networks, they had significantly decreased network strength, decreased global efficiency and increased shortest path length. Moreover, bipolar patients had reduced efficiencies in several parietal, temporal, frontal, occipital and limbic regions. These findings may improve our understanding of the potential mechanisms of the underlying neurobiological basis of bipolar disorder.
