Introduction
Omega-3 polyunsaturated fatty acids (PUFA) include eicosapentaeoic acid (EPA) and docosahexaenoic acid (DHA). They are believed to be protective in cardiovascular disease due to their anti-infammatory properties.
Omega-3 in mental health
Aults
Recent large meta-analysis of large number of placebo-controlled trials of PUFA for different indications revealed the following (1):
- significant clinical benefit of omega-3 treatment in major depressive disorder (MDD) and bipolar disorder
- significant clinical benefit of omega-3 treatment in depressive symtpoms in adults without MDD.
- EPA (not DHA) is responsible for clinical efficasy.
There was no benefit in prevention of depression, or treatment of peripartum depression, schizophrenia, or dementia.
Children and Adolescents
- A study of adolescents at risk for psychosis, omega-3 fatty acids significantly reduced positivesymptoms, negative symptoms, and improved functioning, but had no significant effect on depressive symptoms. (2)
- A small RCT of depressed pre-teens found positive effect of omega-3 fatty acids in improving the mood.(3)
- Among children and adolescents with autism omega-3 fatty acids reduced severe tantrums, aggression, or self-injurious behavior at 6 weeks. (4)
