  3. Patient has been off medications for one week prior to study enrollment.
  4. Patient has a Hamilton Depression Rating Scale (HDRS) total score ≥20
  5. Patient is between the ages of 12 and 35 years.

Exclusion criteria: All subjects will be excluded from participation for the following reasons:

  1. Any chemical use disorder within 3 months.
  2. Any history of significant suicidality that would place the patient at risk to participate in this protocol.
  3. Current score ≥3 on item 3 of the HDRS-17 (Suicide Item)
  4. Any medical or neurological disorder that could influence fMRI results.
  5. A history of mental retardation or an estimated IQ total score <85.

  7. The patient lives >100 miles from the University of Cincinnati or cannot attend follow-up visits.
  8. Meets DSM-IV criteria for a bipolar mixed episode
