Summary

This will be a prospective, open-label, single-arm study to determine the safety and feasibility of an intensive treatment of transcranial direct current stimulation (tDCS) for major depressive disorder (MDD). Participants will be age 18-65 with a diagnosis of unipolar MDD. Participants will receive an intensive treatment of tDCS over a 10-day treatment period and complete follow-up assessments at the end of treatment, 1, and 4 weeks post-treatment.

Detailed description

This will be a prospective, open-label, single-arm study to determine the safety and feasibility of an intensive treatment of transcranial direct current stimulation (tDCS) for major depressive disorder (MDD). Secondary objective is to gather preliminary data on the clinical effects of the protocol. After assessment and inclusion into the study, participants will receive up to 50 tDCS sessions over 10 days. Study procedures: Daily assessments: brief questions before and after each tDCS session to evaluate potential adverse events as well as a verbal rating scale for pain. Questionnaires : a battery of mood questionnaires will be completed to inform findings regarding clinical effects of the treatment. Cognitive measures: a short cognitive assessment will be completed to inform findings regarding cognitive safety of the treatment.
