About this study

Official title: New Form of Brain Stimulation Targeting Dorsomedial Prefrontal Cortex in Treating Refractory Depression and the Predictive Biomarkers of Antidepressant Efficacy

Major depressive disorder (MDD) is a common and troublesome disorder, with high risk of physical and psychiatric comorbidity. At least one-third of patients could not achieve a response after several antidepressant trials, so-called treatment-refractory depression (TRD). The high-frequency repetitive transcranial magnetic stimulation (rTMS) or intermittent theta-burst stimulation (iTBS) at left-sided dorsolateral prefrontal cortex (DLPFC) have a response rate of 40-60%. Obviously, not all TRD patients achieve the remitted state after treatment with antidepressants or DLPFC-rTMS, which may result from the heterogeneity of MDD. More and more evidence, such as brain lesion studies, deep brain stimulation, open-labeled rTMS case series, and neuroimaging studies, suggests that dorsomedial prefrontal cortex (DMPFC) might play a more central role in the pathophysiology of major depression. The DMPFC demonstrated as a "dorsal nexus" phenomenon in depression, which means a unique brain region where cortical networks for affect regulation, default mode control and cognitive control coverage in depressed subjects but not in healthy persons. In addition, another meta-analysis of resting-state functional MRI (fMRI) demonstrated the abnormal functional connectivity from DMPFC. These abnormalities of networks were highly associated with several depressive symptoms such as anhedonia, emotional regulation, somatic markers, rumination, self-reflection, poor attention and poor decision-making. However, only a handful of studies investigated the brain stimulation targeting DMPFC and the further changes in brain functional connectivity. The clinical efficacy and the fMRI changes of prolonged intermittent theta-burst stimulation (piTBS) and 20Hz- rTMS targeting bilateral DMPFC were investigated, and the predictive value of baseline networks by fMRI for antidepressant responses was also assessed to find a reliable approach to gauge treatment response prospectively.

Read the detailed description

Several open label studies showed the preliminary clinical efficacy of DMPFC stimulation, but there was no randomized sham-control trial to confirm the clinical efficacy in Asian people. In addition, there were also few fMRI studies to express the brain circuit changes after DMPFC stimulation. The clinical efficacy and the fMRI changes of prolonged intermittent theta-burst stimulation (piTBS) and 20Hz- rTMS targeting bilateral DMPFC were investigated, and the predictive value of baseline networks by fMRI for antidepressant responses was also assessed to find a reliable approach to gauge treatment response prospectively. All patients with TRD who failed at least one antidepressant trial are randomized to three groups (Group-A: piTBS treatment; Group-B: 20Hz-rTMS treatment; Group-C: sham treatment). Before and after 20 sessions targeting bilateral DMPFC over ten days, structural and functional magnetic resonance imaging (MRI) is arranged for each participant. In addition, pre- and post-treatment fMRI data are analyzed for each patient to investigate the networks and local brain activity changes between groups.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Prolonged intermittent theta burst stimulation (piTBS)Device

    Participants in the prolonged dosage (1800 pulse) of intermittent TBS (iTBS) active stimulation group will receive 2-week three-pulse 50-Hz bursts administered every 200 milliseconds (at 5 Hz) at an intensity of 80% active motor threshold (MT) to the bilateral DMPFC, twice a day. Stimulation will be delivered to the DMPFC using a stimulator.

  • 20Hz rTMSDevice

    Participants in the 20 Hz rTMS (2000 pulse) active stimulation group will receive 2-week 2s- and-10s off, total 50 cycles at each hemisphere/session, at an intensity of 100% resting motor threshold (MT) to the bilateral DMPFC, twice a day. Stimulation will be delivered to the DMPFC using a stimulator.

  • sham controlDevice

    Half of the patients in the sham group received 2-week the same prolonged iTBS parameter stimulation (sham- prolonged iTBS), and the other half received the same 20 Hz rTMS parameter stimulation using a sham coil (sham-20 Hz rTMS), which also improved the blinding process
