Study of Aripiprazole (Abilify) Versus Placebo in Children With Subsyndromal Bipolar Disorder

This will be a double-blind, placebo-controlled, parallel-arm, randomized clinical trial that will last up to 12 weeks. This placebo-controlled portion will be followed by a 6-week open label extension/stabilization phase. In order to be eligible for participation in the extension/stabilization phase, subjects must: 1) in the investigator's opinion have had no dose-limiting side effects likely to be attributable to aripiprazole (APZ); 2) participated in the blinded portion of the clinical trial for a minimum of 4 weeks.
