Brief summary
Study hypothesis: psychotherapy and SSRI treatment effect in different brain way: psychotherapy in up to down way and SSRI in down to up way. The investigators will explore this hypothesis in major depressive disorder outpatients with Magnetic Resonance Imaging analysis in this study. Patients in different groups will be treated by psychotherapy or SSRI treatment. They will all be checked with Magnetic Resonance Imaging pro and after 12 weeks of treatment.
Detailed description
Patients meeting the inclusion criteria undergo an examination that included a diagnostic interview, vision test, and psychophysiological measures. Participants then undergo the baseline fMRI scan within 48 hours, after that, they will receive psychotherapy or SSRI treatment.and returned the scan once they completed the therapy.
