Brief Summary:

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.

Condition or disease	Intervention/treatment	Phase
Pediatric Bipolar Spectrum Disorders	Drug: Omega-3; Drug: Inositol	Phase 4

Detailed 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).

Arm	Intervention/treatment
Active Comparator: Omega-3/Placebo; Combination Omega-3 and Placebo treatment.	Drug: Omega-3; Children with bipolar spectrum disorders ages 6-12 will receive treatment with omega-3 fatty acids. Study subjects may be randomized to receive 3000mg (6 500mg capsules) of omega-3 fatty acids for the duration of the study. Omega-3 fatty acid capsules are in the form of Nordic Naturals brand, ProOmega Junior, which contains 325mg EPA and 225mg DHA per two capsules.; Other Name: ProOmega Junior
Active Comparator: Placebo/Inositol; Combination Placebo and Inositol treatment.	Drug: Inositol; Children with bipolar spectrum disorders ages 6-12 will receive treatment with inositol, omega-3 fatty acids, or both weekly for 12 weeks. Subjects weighing 25kg or more may be randomized to receive 2000mg (4 500mg capsules) of inositol (80mg/kg for a 25kg child). Children weighing less than 25kg will be dosed at 80mg/kg rounded down to the nearest thousand mg dose. Dosage will remain constant throughout the study.

Outcome Measures

Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :

1. Improvement in mania symptoms by change in Young Mania Rating Scale (YMRS) [ Time Frame: baseline to 12 weeks ]
   Primary outcome measure of efficacy will be assessed by mean change from baseline to endpoint in the Young Mania Rating Scale (YMRS) total score.
2. Improvement in depression symptoms by Children's Depression Rating Scale (CDRS) [ Time Frame: baseline to 12 weeks ]
   Primary outcome measures of efficacy will be assessed by mean change from baseline on the Children's Depression Rating Scale (CDRS).
