Zapping away loneliness: brain stimulation trial targets mild depression

This study tests whether a non-invasive brain stimulation technique called transcranial direct current stimulation (tDCS) can reduce feelings of loneliness and improve mood in people with mild depression (subthreshold depression). Researchers will enroll 204 adults who have some depressive symptoms but not full-blown major depression. Participants will receive multiple sessions of personalized tDCS, and changes in loneliness and mood will be measured.
