The purpose of this study is to see if creatine, which is a naturally occurring chemical in the body, is effective for treating Major Depressive Disorder (MDD) in female teenagers. Creatine may have effects of interest in the brain. The reason for the MRI component of this study is to learn about new ways to see inside the brain. The investigators will use magnetic fields and radio waves to look at the brain and chemicals in the brain. The investigators hope that this technique will have medial use in the future.
The primary hypothesis of the study is that oral creatine supplementation will have a beneficial effect as adjunctive therapy in female adolescents with MDD who are non-responders to an adequate trial of the SSRIs Fluoxetine or Escitalopram.

- Mean Children's Depression Rating Scale (CDRS-R) [Reference: Poznanski EO et al. Preliminary Studies of the Reliability and Validity of the Children's Depression Rating Scale. J Am Acad Child Psychiatry. 1984 Mar;23(2):191-7.] [ Time Frame: 8 weeks ]The CDRS-R is a 17-item scale, with items ranging from 1 to 5 or 1 to 7 (possible total score from 17 to 113), rated by a clinician via interviews with the child or parent. Scores ≥40 are indicative of depression, whereas scores ≤28 is often used to define remission
- 31-phosphorus Magnetic Resonance Spectroscopy Phosphocreatine Metabolite [ Time Frame: 8 weeks ]Phosphocreatine Metabolite is a phosphorylated creatine molecule that plays a role in the production of the energy in the body. Phosphocreatine (PCr) metabolite was quantified by calculating the ratio of PCr over total phosphorus resonance from 31-Phosphorus Magnetic Resonance Spectroscopy.
