Keywords: Psychiatric Disorders, fMRI (resting state)This study aimed to explore the dynamic FC in adolescent MDD patients, with a focus on the temporal properties of functional connectivity states as well as the variability of network topological organization. We found that adolescent MDD patients spent more time in the weakly-connected and relatively highly-modularized State 1, spent less time in the strongly-connected and low-modularized State 2, and had higher variability in the network efficiency than healthy controls. These findings suggest impaired local segregation and global integration of functional networks, as well as segregation-integration imbalance in adolescent MDD patients.
