Study Summary

The objectives of this study are to study the safety, effectiveness, tolerability and dosing regimen of risperidone, and olanzapine, in the treatment of mania in Bipolar Disorder I and Bipolar II Disorder in preschool children over an 8 week period. We hypothesize that these atypical neuroleptics may be effective in treating pediatric mania, with a lower risk of extrapyramidal side effects.

Interventions

  • DRUG risperidone (Risperdal)
