Brief Summary
The project will investigate the use of a novel neuromodulatory technique, transcranial direct current stimulation (tDCS) in the treatment of patients with major depressive disorder. Hypothesis 1: Active tDCS will improve depressive symptomology to a significantly greater degree than sham treatment. Hypothesis 2: Active tDCS will be well tolerated and free of major side effects.

Outcome Measures
Primary Outcomes (1)
Hamilton Rating Scale for Depression (HAMD), 17-item version
The Hamilton Depression Scale (HAMD) is a clinician administered test measuring the severity of depressive symptoms in adults and children.
Baseline and at 3 weeks
Study Arms (2)
Active 2mA tDCS
EXPERIMENTALThe stimulator will be used to deliver anodal stimulation to the left prefrontal cortex and cathodal stimulation to the right prefrontal cortex. The placement of the anode is proposed to enhance activity in the left frontal cortex; the cathode aims to reduce activity in the right prefrontal cortex.
Sham tDCS
SHAM COMPARATORThe system setup is identical to that of active tDCS; however, the stimulator will be turned off after 30 seconds.
Interventions
Delivery of mild current to specified brain regions.
