Brief Summary
This study evaluates an association between different dosage and the antidepressant efficacy of theta burst stimulation in patients with treatment-resistant depression. In a double-blind design, All patients are randomized to three groups, i.e. standardized dosage intermittent theta-burst stimulation treatment, high dosage intermittent theta-burst stimulation treatment or sham treatment.

Outcome Measures
Primary Outcomes (1)
Percentage change in 17-item Hamilton Depression Rating Scale
the altered percentage of 17-item Hamilton Depression Rating Scale (range, 0 to 52, with higher scores indicating more depression)

Study Arms (3)
Active standardized iTBS-DMPFC
EXPERIMENTALThis active group will receive standardized dosage of intermittent theta-burst on dorsomedial prefrontal cortex(DMPFC)
Active high-dosage iTBS-DMPFC
EXPERIMENTALThis active group will receive high dosage of intermittent theta-burst on dorsomedial prefrontal cortex(DMPFC)
Sham standardized iTBS-DMPFC or high-dosage iTBS-DMPFC
SHAM COMPARATORPatients in the sham group will receive the same standardized or high-dosage iTBS performing by a sham coil
Interventions
Participants in the standardized dosage(600 pulse) of intermittent TBS(iTBS) active stimulation group will receive 3-week three-pulse 50-Hz bursts administered every 200 milliseconds (at 5 Hz) at an intensity of 80% active motor threshold (MT) to bilateral DMPF, twice a day. Bilateral side DMPFC will be targeted by MRI-neuronavigation system. Stimulation will be delivered to the DMPFC using a Magstim stimulator.
Participants in the standardized dosage(1800pulse) of intermittent TBS(iTBS) active stimulation group will receive 3-week three-pulse 50-Hz bursts administered every 200 milliseconds (at 5 Hz) at an intensity of 80% active motor threshold (MT) to bilateral DMPF, twice a day. Bilateral side DMPFC will be targeted by MRI-neuronavigation system. Stimulation will be delivered to the DMPFC using a Magstim stimulator.
Half of the patients in the sham group received 3-week the same standardized iTBS parameter stimulation (standardized sham-iTBS), and the other half received the same high dosage iTBS parameter stimulation using a sham coil (high dosage sham-rTMS), which also improved the blinding process
Eligibility Criteria
You may qualify if:
- Male or female, 21 to 70 years of age.
- Diagnosed with the recurrent Major depressive disorder (MDD) and currently having a Major Depressive Episode (MDE)
- Participants failed to respond to at least one adequate antidepressant treatment in their current episode
- Participants have a Clinical Global Impression - Severity score of at least 4 and a total score of at least 18 on the Hamilton Depression Rating Scale (HDRS-17) at both screening and baseline visits ( Day -14 and Day 0)
- Participants must discontinue their antidepressant medications at least for one week ( at least two weeks if Fluoxetine) prior to the TMS intervention and keep antidepressant-free during the study duration.
- Participants also failed to respond to one complete left-sided DLPFC 10Hz rTMS/piTBS treatment course.
You may not qualify if:
- a lifetime psychiatric history of bipolar disorder, schizophrenia, psychotic disorders, or organic mental disorder including substance abuse and dependence (based on DSM-IV criteria)
- Participants with a lifetime medical history of major systemic illness and clinically significantly abnormal screening examination that might affect safety, study participation, or confound interpretation of study results.
- Participants with a lifetime medical history of neurological disorder records (e.g., stroke, seizure, traumatic brain injury, post brain surgery), brain implants (neurostimulators), cardiac pacemakers
- Women with breastfeeding or pregnancy
- Participants with a current strong suicidal risk (i.e., a score of 4 on item 3 of the HDRS-17)
