Adaptive tDCS for Treatment-Resistant MDD

Brief Summary

This pilot study aims to investigate the potential role of transcranial direct current stimulation (tDCS) in the treatment of treatment-resistant major depressive disorder (MDD). tDCS is a noninvasive brain stimulation technique which has been utilized for the treatment of major depression in several studies, both as a primary and adjunctive treatment. The treatment will be administered under the supervision of a physician with experience in administering the treatment and monitoring for complications. This will be a prospective "adaptive tDCS stimulation" open label research study. Participants will receive 20 minute sessions of up to 4 milliamps (mA) transcutaneous electrical stimulation sessions over 4 to 6 weeks. Building on the theory that greater current "dose" may be a significant factor in determining efficacy, this study aims to determine whether higher tDCS current doses lead to greater improvements in depressive symptoms in this population of patients with treatment-resistant major depressive disorder.
