Applying mild electrical currents to the brain has been shown to be an effective treatment for depression. But could the treatment also benefit people with bipolar disorder?
Transcranial Direct Current Stimulation (tDCS) is a safe, non-invasive technique that involves the passing of a very weak direct current into the brain through electrodes on the scalp. Patients remain awake and alert during the procedure.
The largest randomised controlled trial of tDCS ever undertaken, conducted by the University of New South Wales (UNSW) and the Black Dog Institute, recently confirmed the treatment’s significant antidepressant effects.
