简要总结
This trial will compare the efficacy and tolerability of 20 Hz vs. 1 Hz vs. sham repetitive transcranial magnetic stimulation targeting the dorsomedial prefrontal cortex, delivered twice daily over 15 days, in patients with a diagnosis of major depressive disorder. The trial will include structural and functional MRI, EEG, and behavioral measures obtained before, during, and after treatment.

结局指标
主要结局
HAM-D17 score
时间窗: Baseline, after each week (10 sessions) of treatment, and 2, 6, and 12 weeks post-treatment
Outcome measured by a change in HAM-D17 score from baseline to 2 weeks post-treatment. A 50% improvement in the score is considered a response to rTMS. A final score of \<8 is categorized as remission.
次要结局
- Beck anxiety inventory(Baseline, after each week (10 sessions) of treatment, and 2, 6, and 12 weeks post-treatment)
- Beck Depression Inventory-II(Baseline, after each week (10 sessions) of treatment, and 2, 6, and 12 weeks post-treatment)
