Outcome Measures

Primary Outcomes (2)

  • Translocator protein total distribution volume in prefrontal cortex, anterior cingulate cortex, and hippocampus

    PET scan measures in DNP-mild and DNP-moderate compared to healthy controls

    within 3 to 4 weeks after initiation of screening

  • Monoamine oxidase B total distribution volume in prefrontal cortex, anterior cingulate cortex, and hippocampus

Study Population

Participants that have recovered from mild or moderate COVID-19 respiratory symptoms and have a new onset major depressive episode (MDE).

You may qualify if:

  • Age 18 to 80
  • Diagnosis of COVID-19
  • Recovered from mild or moderate COVID-19 symptoms. Mild is defined as no evidence of pneumonia or hypoxia. Moderate is defined as presence of clinical symptoms of pneumonia but not severe enough to require ongoing use of supplementary oxygen.
  • Recovered from physical COVID-19 symptoms including cough, shortness of breath, fever, chills, or gastrointestinal upset for at least 4 weeks
  • New onset major depressive episode (MDE) within 3 months after COVID-19, as verified by the Research Version of Structured Clinical Interview for DSM 5 (SCID-5-RV)
  • High-affinity-binder (HAB) or mixed-affinity-binder (MAB) genotype for rs6971 polymorphism, based on saliva genetic testing

You may not qualify if:

  • Lifetime history of an autoimmune disease
  • Lifetime history of a neurological disease, excluding migraine
  • Lifetime diagnosis of Antisocial or Borderline Personality disorder
  • Lifetime history of psychotic symptoms prior to COVID-19
  • Lifetime diagnosis of Substance of Alcohol Use Disorder
  • Use of street drugs, including marijuana, in the past two months
  • Presence of cigarette smoking in the past two months
  • Positive urine drug or cotinine screen at any timepoint during the study
  • Currently pregnant
  • Currently breastfeeding
  • Use of aspirin or ibuprofen within the past 2 weeks
  • Use of any other anti-inflammatory medication or MAO-B inhibitors within the past 4 weeks
  • Use of herbal remedies in the past month
  • Presence of metal implant, object or electrical devices that are contraindicated for MRI
  • Current disorders of coagulation, blood or ongoing use of anticoagulant medication
  • +4 more criteria
