Brief Summary

In this project, we will A) track the functioning of a collection of potential neurobiological targets for depression over time, B) examine how fluctuations in the functioning of those targets relates to real-world functioning, and C) in a subset of the sample, determine how the functioning in those targets is altered by a single dose of ketamine.

Eligibility Criteria

Inclusion Criteria

All participants will:

1. be between the ages of 18 and 60 years,

2. score ≥ 14 on the Hamilton Depression Rating Scale (Ham-D)

3. possess a level of understanding sufficient to agree to all tests and examinations required by the protocol and must sign an informed consent document

Exclusion Criteria

All participants:

1. Presence of lifetime bipolar, psychotic, or autism spectrum; current problematic substance use (e.g., ongoing moderate-to-severe substance use disorder);

4. Changes made to treatment regimen within 4 weeks of baseline assessment.

5. Reading level <6th grade as per patient self-report.

6. Patients who have received ECT in the past 2 months prior to Screening.

1. Patients currently taking any psychotropic medication.

2. Lifetime recreational ketamine or PCP use

3. Current pregnancy or breastfeeding

4. For ketamine phase entry, patients must be reasonable medical candidates for ketamine infusion, as determined by a physician co-investigator. Serious, unstable medical illnesses including respiratory [obstructive sleep apnea, or history of difficulty with airway management during previous anesthetics], cardiovascular [including ischemic heart disease and uncontrolled hypertension], and neurologic [including history of severe head injury] will be exclusions.

5. Clinically significant abnormal findings of laboratory parameters [including urine toxicology screen for drugs of abuse], physical examination, or ECG.

6. Uncontrolled or poorly controlled hypertension, as determined by a physician co-investigator's review of vitals collected during screening and any other relevant medical history/records.

7. Patients with one or more seizures without a clear and resolved etiology.

8. Patients starting hormonal treatment (e.g., estrogen) in the 3 months prior to Screening.

9. Past intolerance or hypersensitivity to ketamine.

10. Patients taking medications with known activity at the NMDA or AMPA glutamate receptor [e.g., riluzole, amantadine, memantine, topiramate, dextromethorphan, Dcycloserine], or the mu-opioid receptor.

11. Patients taking any of the following medications: St John's Wort, theophylline, tramadol, metrizamide.
