ScienceDaily (2007-05-04) — Bipolar disorder is estimated to affect approximately 1-3 percent of adults, but also can affect children and adolescents. Untreated, this disorder is associated with greater risk of drug and alcohol addiction, interpersonal relationship difficulties, school and, later, work problems, engaging in risky behaviors, and suicide.

A study published in the May issue of The Journal of Pediatrics shows that childhood-onset bipolar disorder is more common than believed and often goes unrecognized and untreated for long periods of time, leading to lower quality of life and greater difficulty in treatment.
