Placebo Controlled Trial of Valproate and Risperidone in Young Children With Bipolar Disorders
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.
The primary aim of this proposal is to conduct a preliminary controlled trial of valproate and risperidone in children ages 3-7 yr. with bipolar disorders. A secondary aim is to carefully characterize these subjects using clinical rating scales and develop pilot data on a very young cohort of children with bipolar disorders that can be used to support an application to NIMH for a prospective, longitudinal study that will provide important information about the course, medication response, neurobiology and outcome of these patients.
