6. Not taking more than two psychotropic medications at time of recruitment to avoid polypharmacy. Participants will not have changed the dose of the medication for at least 8 weeks before enrollment.

Only participants with bipolar 2 disorder diagnosis may be off psychotropic medications at time of enrollment. In that case, they must not have stopped any medications within 8 weeks of enrollment.

Participants can be taking diphenhydramine but no benzodiazepines or other hypnotics as needed at time of enrollment.

7. Genotyping as a medium or high TSPO binding type

Exclusion Criteria

Diagnosis of any other major psychiatric disorders such as lifetime schizophrenia, schizoaffective disorder, current psychotic features of bipolar disorder, or recent moderate substance use disorder (within 4 months of recruitment); IV drug use. Meets DSMV criteria for a manic episode, or Young Mania Rating Scale score >12, at the time of screening.

3. A first-degree family history of schizophrenia if the participant is less than 33 years old.

4. Significant active physical illness, including blood dyscrasias, lymphomas, hypersplenism, endocrinopathies, renal failure, chronic obstructive lung disease, autonomic neuropathies, peripheral vascular disease. Any disorders with inflammation, malignancy, autoimmune or infectious etiology. Systemic blood pressure >140 or diastolic blood pressure >100. Hemoglobin <11 in females or <13 in males.

5. Actively suicidal, as defined by expressing ideation with a plan or intent for suicide or develops suicidal ideation that requires immediate medical or treatment intervention.

7. Lactating Women

8. ECT within the last 6 months

9. Participants who endorse a history of prior head trauma and score 1.5 standard deviations below the mean on Trailmaking A & B test

10. Metal implants, pacemaker, metal prostheses, metal orthodontic appliances or shrapnel in the body

11. Current, past or anticipated exposure to radiation, including

1. Having been badged for radiation exposure in the workplace

2. Participation in nuclear medicine protocols in the last year* *Participants will be eligible, however, if the injected dose and dosimetry of the radiotracer are known and the cumulative annual exposure of the previous studies and this study is lower than the annual limit for research participants defined by FDA (21 CFR 361.1)

12. History of claustrophobia that would prevent the participation in neuroimaging

13. Weight >350 lbs or inability to fit into the MRI scanner**

** If there are doubts that the MRI scanner can accommodate the physical dimensions of the participant, the participant's circumference may be measured to determine if it is less than the MR scanner limit of 55 cm. The participant may also be brought to the MRI Center and the MRI technologist will assess whether the participant will be able to fit into the MRI scanner. Metal screening and urine pregnancy testing will be done in this circumstance before the participant enters the MRI area.

14. Current anticoagulant or anti-platelet treatment including aspirin if needed daily

15. Risks of delay to treatment of known efficacy (up to 9 weeks) are too great for the participant. Risks to consider include A) Severity of presenting symptoms B) History of symptom fluctuations or deterioration C) Psychosocial conditions that make delay to treatment unreasonable
