Brief Summary
Recently, interest has emerged in the use of ketamine as an antidepressant. Recent placebo-controlled clinical trials administering a single dose and an open label trial giving repeated doses shown that ketamine is markedly superior to placebo at reducing depression, including in treatment-resistant patients, and that its antidepressant effects have a very rapid onset. This clinical study consists of two phases. In Phase I, participants who satisfy inclusion criteria will receive ketamine at variable doses (0.1mg/kg-0.5mg/kg) or a placebo (saline, or 0.01mg/kg midazolam) once a week over up to 6 weeks. If participants qualify for Phase II, they will receive repeated sessions of ketamine at variable doses over three weeks. During both phases, mood, psychiatric, and neuropsychological outcomes will be measured.

Outcome Measures
Primary Outcomes (1)
Change from baseline on depression rating scales
Before, 4 hours after, and 24 hours after ketamine session
Secondary Outcomes (1)
Psychiatric side effects (BPRS, CADSS) and memory tests
Cognitive battery done before and after 3 weeks; side effects measured immediately before and 4 hours after each ketamine session in both phases.
Interventions
