Brief Summary

This study will examine the effectiveness of omega-3 fatty acids, compounds found in plants and fish, in treating bipolar disorder. Some studies have indicated that omega-3 fatty acids may be effective in treating mood disorders. For example, one investigator has shown a correlation between the prevalence of major depression and the amount of fish consumed per capita worldwide. Others have found decreased amounts of EPA (one of the active ingredients in omega-3 fatty acids) in the red blood cells of patients with major depression. And a recent small study of patients with bipolar illness indicated that omega-3 fatty acids prevented relapses, especially of depression, in patients. Patients with bipolar disorder who are not benefiting satisfactorily on their current medications are eligible to participate in this study. Candidates will be screened with a psychiatric evaluation, routine blood tests, a urine test and other tests needed to monitor medications. Participants will be randomly assigned to one of two groups: one group will receive 6 grams of omega-3 fatty acid every day for 16 weeks; the second will receive a placebo (inactive capsule). In addition, patients in both groups will continue to take their previous medications. Every 2 weeks, all patients will have their vital signs checked and be evaluated for side effects and mood changes. At the end of the 16-week study period, all patients will be given the opportunity to continue in the study for another 8 months and receive active drug (omega-3 fatty acid). Patients who continue will be evaluated once a month and will have blood drawn on the last visit for routine tests.

Patients must meet DSM-IV criteria for Bipolar Disorder, depressed, hypomanic/manic, or rapid-cycling type. Patients must be competent to comprehend the purpose of the study and provide informed consent. Patients must be at least 18 years old. Patients enrolling in the bipolar depression component of the study must have a depression of sufficient severity to rate greater than or equal to 16 on the Inventory of Depressive Symptomatology-Clinician (IDS-C), or the clinician must decide there is a need to treat. Patients enrolling in the bipolar hypomania/mania component of the study must have a hypomania/mania of sufficient severity to rate greater than or equal to 12 on the Young Mania Rating Scale or the clinician must decide that there is a need to treat. Patients enrolling in the bipolar rapid cycling component of the study must have mood fluctuations meeting one or both of the above acute episode criteria in the past 3 months or show a pattern of ultra rapid cycling (4 or more episodes within a month) or ultradian cycling (cycling within a day on 4 or more days/week) on the NIMH-LCM. Patients must not have a serious medical illness. Patients must not have non-insulin dependent diabetes mellitus (NIDDM) or insulin-dependent diabetes mellitus (IDDM). Patients must not have acute suicidal or homicidal ideation.
