About

The primary objective of this study is to determine the effectiveness of serial infusions of intravenous (IV) ketamine in adults with treatment resistant depression (TRD).

Full description

Thus, in the current study we want to naturalistically explore the antidepressant effects of serial slow IV infusions (40 minutes) of ketamine at a dose of 0.5 mg/kg, over a treatment period of 8 weeks in an academic psychiatric hospital. This is a minimal sedation treatment. The primary outcome measure of this study will be remission estimated based on the severity of depressive scores. After the 8 weeks of treatment, there will be a four week observational period. During the observational period, participants will receive treatment as usual and will be contacted over the phone for follow-up questions regarding their overall health status, mood and clinical state. They will also complete a neurocognitive task at the end of the 4 week observational period
