- Children's Depressive Rating Scale - Revised (CDRS-R) [ Time Frame: baseline and 10-weeks ]It 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 and parent. A score of ≥40 is indicative of depression, whereas a score ≤28 is often used to define remission (minimal or no symptoms).
- Clinician's Global Improvement Scale (CGI) [ Time Frame: baseline and 10-week treatment phase ]a 7 point scale that requires the clinician to assess how much the patient's illness has improved or worsened relative to a baseline state at the beginning of the intervention. and rated as: 1, very much improved; 2, much improved; 3, minimally improved; 4, no change; 5, minimally worse; 6, much worse; or 7, very much worse.

Placebo Comparator: Corn Oil
The dosage will correspond to the titration schedule of the Omega-3 Fatty Acid experimental treatment.
Dietary Supplement: Corn oil
The dosage will correspond to the titration schedule of the Omega-3 Fatty Acid experimental treatment. Placebo (corn oil) and omega-3FA capsules will be identical in color and smell.
Experimental: Omega-3 Fatty Acids
The initial dose will be 1.2g/d. This will be increased gradually by 0.6 per 2 weeks to a possible maximum daily dose of 3.6 g/d.
Drug: Omega 3 Fatty Acids
The study medication will consist of combined EPA/DHA with a ratio of 2:1. Dosage will be titrated based on clinical response and side effects. The initial dose will be 1.2g/d. This will be increased gradually by 0.6 per 2 weeks to a possible maximum daily dose of 3.6 g/d. Patients will have to remain on a dose for 2 weeks to provide the opportunity to assess clinical response at any one dose. The total duration of the intervention will be 10 weeks.

This study rests on a confluence of findings showing that: 1) Major depressive disorder (MDD), is a major public health concern that often emerges in adolescence; which entails 2) pathophysiological abnormalities in fronto-striatal structures resulting in death and atrophy of glia and neurons; 3) omega-3 fatty acids (FA) effects on brain function in adolescent MDD can be assessed by proton magnetic resonance spectroscopy (1H MRS); and, 4) it is critical that commonly used complementary and alternative medicines such as omega-3FA that have face validity be tested for their neurobiological effect in MDD.
Using 1H MRSI, this study examines the effects of Omega-3FA on striatal and anterior cingulate cortex (ACC) concentrations of the neurocellular biomarkers total choline (tCho), total creatine (tCr), and γ-aminobutyric acid (GABA, ACC only) in adolescent MDD. Hypotheses are: 1) relative to placebo, omega-3FA treatment will result in significant reductions of striatal and ACC tCho and tCr concentrations, and increased ACC GABA; 2: Regardless of treatment condition (placebo or Omega-3FA), MDD adolescents who are improved at the end of 10-week treatment will exhibit a significant decrease in striatal and ACC tCho and tCr concentrations, and increases in ACC GABA relative to unimproved adolescents.
