Transcranial Direct Current Stimulation to Treat Major Depressive Disorder

This study has been completed.
Information provided by (Responsible Party):
Andre Brunoni, University of Sao Paulo Identifier:
First received: June 22, 2010
Last updated: December 2, 2011
Last verified: December 2011
The investigators purpose is to offer active Transcranial Direct Current Stimulation (tDCS) in patients of the investigators previous study who received either placebo or sertraline and have not responded.

Condition Intervention Phase
Major Depressive Disorder Procedure: transcranial direct current stimulation Phase 2 Phase 3

Study Type: Interventional
Study Design: Intervention Model: Crossover Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: An Open-label, Crossover Study on Major Depressive Disorder Using Transcranial Direct Current Stimulation

Further study details as provided by Andre Brunoni, University of Sao Paulo:

Primary Outcome Measures:
  • Treatment Response [ Time Frame: Week 1 ]
    Response is defined as MADRS <=12 or less than 50% of baseline MADRS (Montgomery Asberg depression rating score).

  • Treatment response [ Time Frame: Week 2 ]
    Response defined as above.

Enrollment: 60
Study Start Date: June 2010
Study Completion Date: December 2011
Primary Completion Date: September 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: active stimulation
In active stimulation, the anode is placed over the left dorsolateral prefrontal cortex and the cathode is placed over the right prefrontal cortex. They are located five centimeters ventrally of the primary motor area, which are located five centimeters laterally of the central point of the scalp (which is located on the intersection of the sagittal and median curves). The device will deliver a charge of 2mA for 30 minutes.
Procedure: transcranial direct current stimulation
Transcranial direct current stimulation will be applied at 2mA, 30 minutes/day, for 10 weekdays consecutively
