Arms and Interventions

Intervention / Treatment |
---|---|
Active Comparator: Repetitive Transcranial magnetic stimulation
|
Setting up a new target for rTMS. In the past research, the common target of rTMS in the treatment of depressive symptom was dorsolateral prefrontal cortex (DLPFC). In this study, we use high frequency rTMS in the occipital lobe are precisely targeted by navigation, by stimulating the primary visual cortex(V1), can affect the orbitofrontal cortex (OFC), which is functionally connected to V1, and thus affect the entire nerve ring pathway excitability, thereby rapidly, effectively and safely improving mood symptoms in the acute phase of bipolar depressive episode. After the target was determined by fMRI navigation and positioning, the subjects were subjected to rTMS for 20 minutes per day with the stimulation intensity of 10Hz and 100% of the motion threshold(MT),stimulation time of each sequence was 5 seconds, stimulation interval was 15 seconds, 3000 pulses per day for 15 days, and the total number of pulses was 45000. |
Sham Comparator: Sham Repetitive Transcranial magnetic stimulation
|
The stimulus intensity was 20% of MT in the Sham Comparator arm, and the remaining parameters were the same as the Active Comparator arm.

Time Frame |
---|---|---|
Montgomery-Asberg Depression Rating Scale(MADRS)
Time Frame: 0-8 weeks
|
Montgomery-Asberg Depression Rating Scale (MADRS) is used to reflect the effect of antidepressant treatment and monitor the change of patients' condition.
The scale is a separate scale, and the score should be based on clinical interviews.
The symptoms should be asked from broad to detailed, so as to accurately score the severity.
The rater must determine whether the score is on the defined score values (0,2,4,6) or between these scores (1,3,5), according to clinical practice.
The scale can be used to score at any time interval.
