Gentle electric currents trialed as new depression treatment

Substantial improvements were experienced by around half the participants in a trial for a new non-invasive treatment for depression, with an even larger number seeing clinically meaningful improvements. Direct Current Stimulation, which delivers barely perceptible electric currents to the scalp, has no known serious side effects and delivered more benefits when participants followed up after a month. The trial was the largest of its type in the world and most of the participants had not responded to other treatments, including medications.
