Patients with treatment-resistant major depressive disorder are needed for a brain imaging research study

Participants have been diagnosed with major depressive disorder and:

  • Are 18-50 years old
  • Are a nonsmoker
  • Have not had beneficial response to at least one antidepressant that raises brain serotonin concentration and at least one antidepressant that raises brain norepinephrine concentration

Qualified participants will have bloodwork, memory testing, one PET scan, and one MRI scan of the brain. Participants may also complete an optional lumbar puncture. Those completing the study will receive a payment of up to $400.
