Patients with major depressive disorder and healthy participants.

For the escitalopram group, the study drug (Lexapro tablets or its generic products) will be used. We will conduct no pharmaceutical intervention in the usual care group, the cross-sectional study group, and the healthy participants group.

AUC of ROC curves in discriminating between depressed and healthy groups calculated using depression diagnostic brain network markers.

-Diagnostic brain network markers for major depressive disorder evaluated longitudinally (0w, 6w, 6m).
-Depression severity (Hamilton Rating Scale for Depression) obtained longitudinally (0w, 6w) in the escitalopram group.
-Depression severity (Hamilton Rating Scale for Depression) obtained longitudinally (0w, 6w) in the usual care group.
