The Role of Omega-3 Fatty Acids in the Treatment of Depression in Children and Adolescents: A Literature Review
Abstract
Depression is one of the most common mental disorders diagnosed in children and adolescents. Many individuals benefit from pharmacotherapy including antidepressants, however, there is a fair likelihood of remission and recurrence. Of the several pathophysiologies, depression has been linked to inflammation. Complementary and alternative medications such as the use of omega-3 fatty acids are gaining popularity given their anti-inflammatory properties. The goal of this literature review is to assess the efficacy and the clinical use of omega-3 fatty acids in children and adolescents with depression. We conducted an extensive literature search on PubMed, Ovid MEDLINE, and PsycINFO from January 1, 2005, to September 2021, for published articles (case reports, systematic review, RCT) in any language. A total of seven published studies were included in our literature review. Results indicated a huge heterogenicity in the studies and hence the clinical use of omega-3 fatty acids as monotherapy in depression was not determined. However, it was well tolerated with an extremely low side effect profile. Further research on the use of omega-3 fatty acids as an adjunct to antidepressants would be valuable.
