Accelerated High-Dose tDCS for Depression

RecruitingNA

Sponsor: Medical University of South Carolina

Conditions: Major Depression, Major Depression Disorders

Interventions: Transcranial Direct Current Stimulation (tDCS)

Countries: United States

In this study, investigators are testing whether a higher dose of a non-invasive brain stimulation technique, called transcranial direct current stimulation (tDCS), can be safely used in people with depression. Participants will come to the Brain Stimulation Lab and receive mild electrical stimulation through electrodes placed on their scalp. The study begins with a safety run-in, where the first few participants will receive stimulation at gradually increasing levels (2, 4, and 6 milliamps) while being closely monitored. If no serious side effects are found, later participants will receive repeated 6 milliamp sessions for 5 days total. Investigators will check skin comfort, mood, and overall tolerability after each session.
