Medically healthy Veterans ages 21-75 that have been diagnosed with Depression will get up to 6 treatments of Ketamine infusions, weekly. After treatment is completed, follow up will occur at 1 month, 3 months, and 6 months after completion of infusions to evaluate the longer term effects of ketamine.

A total of 25 depressed subjects between the ages of 21-75 who have current major depressive disorder without psychotic features by DSM-5 will be recruited. Subjects will be accepted into the protocol after an opportunity to review and provide voluntary written informed consent and completion of a comprehensive medical and psychiatric history, physical examination, mental status examination, and routine laboratory assessments. Patients will be recruited in outpatient settings to the Refractory Depression Clinic. Providers or Refractory Depression consult team will be informed if the patient may be eligible for participation in the ketamine protocol. Subjects must have established care in the VA Connecticut Healthcare System. If the Veteran is interested, a screening visit for further evaluation for the ketamine protocol will be scheduled. Veterans will receive up to 6 infusions for ketamine weekly, per PI discretion. The primary goal of this proposal is to test the effectiveness of repeated ketamine treatment (0.5 mg/kg; once or twice a week for up to 6 weeks; up to a total of 6 ketamine infusions). An open-label trial will be conducted that will include up to 25 Veterans with MDD with a follow-up of 6 months. This open-label trial will allow us to examine the safety and tolerability of the ketamine treatment in this population and the long-term effects. All patients will receive usual standard care during this trial.

The C-SSRS has both lifetime/recent and since last visit versions. The "Lifetime/Recent" version gathers information on lifetime history of suicidality and recent suicidal ideation/self-injurious behavior. The "Since Last Visit" version of the C-SSRS asks about any suicidal thoughts or behaviors the subject has exhibited since the last time administered the C-SSRS.
Time frame: Baseline
The Q-LES-Q is a self-report measure of quality of life.
Time frame: 140 mins after infusion
A standard computerized battery will be done to assess cognitive ability post treatment of ketamine. The battery will include a wide range on cognitive tasks including but not
limited to attention, learning, and working memory. While it is know ketamine causes acute cognitive effects, the longer-term effects of ketamine are not known. When the cognitive battery is being conducted on test days it will be done at the end of the test day, to eliminate the confounding effects of acute treatment of ketamine..
