Omega-3s for Borderline Personality Disorder

Omega-3 fatty acids have shown efficacy in the treatment of symptomatic dimensions of borderline personality disorder. According to researchers from the Hospital Clínico San Carlos, Madrid, Spain, recent analysis of this disorder has allowed the identification a variety of symptoms that can be improved with psychopharmacological treatment, and this includes fish oil.1 The researchers found that the complex symptoms could be divided into four clinical dimensions: impulsive-aggressive, affective-instability, cognitive-perceptive and anxiety-inhibition. Among the other psychopharmacological approaches are antidepressants, mood stabilizers, antipsychotics, and anxiolytics; all are drugs. However, omega-3 fatty acids, recent additions to this pharmacopeia, albeit common dietary supplements, have shown efficacy in the treatment of borderline personality disorder without the many side effects of the drugs.
