About
The purpose of this study is to a) evaluate the efficacy of omega-3 fatty acids versus inositol in the treatment of pediatric bipolar disorder, b) evaluate the efficacy of omega-3 fatty acid plus inositol in the treatment of pediatric bipolar disorder, and c) assess the side effect profile of omega-3 fatty acids plus inositol. This study will be a 12-week trial with children ages 5-12 years old with bipolar spectrum disorders.
Full description
The investigators propose to conduct a randomized, double blind, controlled trial that will evaluate effectiveness and tolerability of omega-3 fatty acids and inositol used alone and in combination. The investigators plan to decrease the variability in the population under study by limiting the age range to 5-12 years and excluding cases with significant, untreated, comorbidity. The cognitive effects/side effects with a neuropsychological battery pre and post treatment will be measured. Subjects with a history of failing treatment with two or more conventional treatments will be excluded.
This will be a 12-week, double-blind, randomized clinical trial study to compare efficacy and tolerability of the natural treatments omega-3 fatty acids and inositol used in combination in the treatment of bipolar spectrum disorders in children and adolescents (ages 5-12). Subjects will be randomized in double blind fashion to one of three arms: omega-3 fatty acids, inositol or the combined treatment. Further, the proposed study will include measures of cognition prior to starting study medication and at endpoint. The investigators will minimize the variability of the population under study by limiting the age range to 5-12 years, minimizing untreated or clinically significant comorbidity and excluding subjects who have already failed treatment with 2 or more anti-manic agents. Subjects will include youth ages 5-12 years with a bipolar spectrum disorder (type I, II, or NOS), mixed, manic, or hypomanic state, according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (American Psychiatric Association, 2000) (DSM-IV), randomized to 3 treatment arms: 1) treatment with omega-3 fatty acids (N=20); 2) treatment with inositol (N=20); 3) treatment with the combination of inositol and omega-3 fatty acids (N=20).

- Subjects must have an initial score on the YMRS total score of at least 20.
- Subject must be able to swallow pills.
- Subjects with ADHD and ODD will be allowed to participate in the study provided that the impairment associated with these disorders is of mild or moderate severity (not severe) and milder in severity relative to the impairment of the bipolar disorder, according to clinician evaluation. Subjects with comorbid anxiety disorders will be allowed to participate provided that the impairment associated with the anxiety is of minimal severity, according to clinician evaluation. Subjects with comorbid CD will be excluded.
