January 24, 2017 updated by: Ybrain Inc.
Study Type: Interventional Study Design: Allocation: Randomized Endpoint Classification: Safety/Efficacy Study Intervention Model: Parallel Assignment Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor) Primary Purpose: Treatment

Study Overview

Detailed Description

Patients will be randomized to receive either real or sham-tDCS as well as anti-depressant drugs. tDCS will be applied over the left (anode) and right (cathode) dorsolateral prefrontal cortex (DLPFC). Patients will visit the hospital to get tDCS administrations 5 days a week for 2 weeks. They will be evaluated every 2 weeks.
