[show abstract][hide abstract] ABSTRACT: Introduction. This paper focuses on the application of Magnetic Resonance Spectroscopy (MRS) to the study of Major Depressive Disorder (MDD) in children and adolescents. Method. A literature search using the National Institutes of Health's PubMed database was conducted to identify indexed peer-reviewed MRS studies in pediatric patients with MDD. Results. The literature search yielded 18 articles reporting original MRS data in pediatric MDD. Neurochemical alterations in Choline, Glutamate, and N-Acetyl Aspartate are associated with pediatric MDD, suggesting pathophysiologic continuity with adult MDD. Conclusions. The MRS literature in pediatric MDD is modest but growing. In studies that are methodologically comparable, the results have been consistent. Because it offers a noninvasive and repeatable measurement of relevant in vivo brain chemistry, MRS has the potential to provide insights into the pathophysiology of MDD as well as the mediators and moderators of treatment response.

[show abstract][hide abstract] ABSTRACT: This article discusses recent findings on the neurobiology of pediatric depression as well as the interplay between genetic and environmental factors in determining the risk for the disorder. Utilizing data from both animal and human studies, the authors focus on the evolving understanding of the developmental neurobiology of emotional regulation, cognitive function and social behavior as it applies to the risk and clinical course of depression. Treatment implications and directions for future research are also discussed.
