  Purpose
We intend to investigate whether deep transcranial magnetic stimulation (DTMS), a novel brain stimulation technique, is effective for treating major depression. We hypothesize that 4 weeks of DTMS will be associated with significant improvements in depressive and anxious symptoms without significant side effects.

Major Depressive Disorder Device: Deep Transcranial Magnetic Stimulation (DTMS) Phase 2 Phase 3

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Effectiveness of Deep Transcranial Magnetic Stimulation for Treating Major Depression: a Pilot Study

Further study details as provided by MARCELO T. BERLIM, Douglas Mental Health University Institute:

Primary Outcome Measures:
  • 21-item Hamilton Depression Rating Scale (HAM-D21) [ Time Frame: week 5 ]
    Response to treatment is defined as a ≥ 50% reduction in the scores of the HAM-D21. Remission is defined as a HAM-D21 score ≤ 9.


Secondary Outcome Measures:
  • Quick Inventory of Depressive Symptomatology - Self-Report (QIDS-SR) [ Time Frame: week 5 ]
    Response to treatment is defined as a ≥ 50% reduction in the scores of the QIDS-SR. Remission is defined as a QIDS-SR score ≤ 5.


Enrollment: 18
Study Start Date: October 2011
Study Completion Date: December 2012
Primary Completion Date: December 2012 (Final data collection date for primary outcome measure)
Intervention Details:
    Device: Deep Transcranial Magnetic Stimulation (DTMS)
    DTMS will be administered according to the following parameters: 18 Hz in 84 trains of 2 seconds duration, with 20 seconds inter-train interval (3,024 pulses per session) at 120% of the resting motor threshold.
Detailed Description:
The aim of this pilot study is to assess, naturalistically, the effectiveness of deep transcranial magnetic stimulation (DTMS) in a sample of subjects with treatment-resistant depression. To do this, enrolled depressed outpatients will be assigned to receive 4 weeks of daily DTMS and will be evaluated at baseline and during week 5. We hypothesize that treatment with DTMS will be associated with significant clinical improvements in depressive and anxious symptoms, and will be well tolerated.
