An EEG Study of Intravenous Ketamine for Major Depression Disorder

This study will enroll 35 patients with major depressive disorder. Candidates for participation in the study will typically be either referred to the clinic through their healthcare provider or will have sought out participation on their own accord based on advertising. Subjects will be screened for eligibility and suitable patients will be invited to attend a screening visit in the clinic and complete informed consent. Upon determining eligibility, subjects will have their first treatment session booked within 42 days of screening (Baseline, visit 0). Three subsequent weekly (±3 days) ketamine therapy treatment sessions will occur on days 7, 14 and 21, for a total of four ketamine infusions over four weeks. All patients will return for a follow-up visit at 4-weeks post final treatment visit, day 49.
