Detailed Description
Repetitive transcranial magnetic stimulation (rTMS) is an established therapy for treatment-resistant depression. The dorsomedial prefrontal cortex (DMPFC), which serves as a connection intermediary of the aberrant functional network in cognitive control and rumination in depression, has been shown to be highly correlated with disease manifestations and post-treatment improvements through several studies involving neuroimaging and brain injury. Research has shown that the response of DMPFC to rTMS is more subject to improving the dimensions of anxiety and insomnia in depression. Therefore, exploring the novel target DMPFC is also beneficial for distinguishing disease dimensions in the future, thereby enabling personalized treatment and improving clinical treatment efficacy.
After being informed about the study and potential risks. All patients giving written informed consent will undergo a screening period to determine eligibility for study entry. At week 0, patients who meet the eligibility requirements will be randomized in a double-blind manner in a 2:1 ratio to the active rTMS group, or sham-control group. Then all participants will undergo a 21-day rTMS modulation and a three- and nine-week follow-up visit.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: active rTMS treatment 3 sessions of active rTMS would be delivered to the left DMPFC daily, with a session of 1800 pulse. |
Device: active rTMS treatment
Participants will receive 3 sessions per day of 1800 pulses per session, lasting for 21 days. Individualized targets will be generated using the pBFS method.
|
| Sham Comparator: sham control 3 sessions of sham rTMS would be delivered to the left DMPFC daily, with a session of 1800 pulse. |
Device: sham rTMS treatment
The parameters in the sham arms are the same as the active stimulation groups. Stimulation was delivered by the same device as the active group fitted with a sham coil.

Outcome Measures
Primary Outcome Measures
- Change in Montgomery-Asberg Depression Rating Scale (MADRS) scores from baseline to Immediate Post-treatment [Baseline and Day 21(Immediate Post-treatment)]]
The Montgomery-Asberg Depression Rating Scale (MADRS) is a validated instrument stratifying the severity of depressive episodes in adults. The MADRS has an overall score ranging from 0 (no depression) to 60 (worst depression).
Secondary Outcome Measures
- Remission and response rates were estimated using Montgomery-Asberg Depression Rating Scale(MADRS) [Baseline, Day 21 (Immediate Post-treatment)]
The response is defined as a symptom improvement of ≥50% and remission is defined as a score ≤10 on MADRS
- Remission and response rates were estimated using Hamilton Depression Rating Scale (HAMD-17) [Baseline, Day 21 (Immediate Post-treatment)]
The Hamilton Depression Rating Scale (HAMD) is the most widely used clinician-administered depression assessment scale. The HAMD-17 version consists of 17 items，and has an overall score ranging from 0 (no depression) to 52 (worst depression). Higher scores represent higher depression severity. The response is defined as a symptom improvement of ≥50% and remission is defined as a score ≤7 on HAMD-17
- Changes in the MADRS from baseline to each visit [Baseline, Day 21 (Immediate Post-treatment), 3-week Post-treatment, 9-week Post-treatment]
The MADRS has an overall score ranging from 0 (no depression) to 60 (worst depression). Higher scores represent higher depression severity.
- Changes in the HAMD-17 from baseline to each visit [Baseline, Day 21 (Immediate Post-treatment), 3-week Post-treatment, 9-week Post-treatment]
The Hamilton Depression Rating Scale (HAMD) is the most widely used clinician-administered depression assessment scale. The HAMD-17 version consists of 17 items，and has an overall score ranging from 0 (no depression) to 52 (worst depression). Higher scores represent higher depression severity.
- cognitive changes from baseline to day 21(Immediate Post-treatment) [Baseline, Day 21 (Immediate Post-treatment)]
Cognitive scores are measured using Chinese brief cognitive test (C-BCT), including Digit Symbol Substitution Test (DSST), continuous performance test (CPT), Trail-Making Test (TMT), Digit Span Test (DST)
