However, there is still little evidence regarding brain functional connectome. After six months of treatment with paroxetine, 56 patients achieved clinical remission and finished their second scan.

Network-based statistics analysis was used to explore the changes in functional connectivity. The results revealed that, compared with Mfd, patients with FED exhibited hypoconnectivity in the somatomotor, default mode and dorsal attention networks, and RD exhibited hyperconnectivity in the somatomotor, salience, executive control, default mode and dorsal attention networks, as well as within and between salience and executive control networks.

Moreover, the disrupted components in Major Depressive Disorder Mdd with current MDD did not change significantly when the patients achieved remission after treatment, and sub-hyperconnectivity and sub-hypoconnectivity were still found in those with remitted RD. Mjaor, the hypoconnectivity in FED and hyperconnectivity in RD were associated with the number of episodes and total illness duration. This study provides initial evidence supporting that impairment of intrinsic functional connectivity across the course of depression is a progressive process.
