Mixed States in Early-Onset Bipolar Disorder

Abstract

Pediatric bipolar disorder (PBD) is a severe and chronic illness. The occurrence of mixed symptoms might add further risk of recurrence of treatment resistance and suicidality. Early recognition and treatment of mixed symptoms might prevent illness progression and development of suicide attempts. This article provides an update on the epidemiology, clinical profile, and treatment of youth with PBD with mixed states. Mixed states in PBD are characterized by higher rates of suicide and more chronic symptoms, and are associated with younger age of onset and greater comorbidity. A careful assessment for mixed states using standardized criteria is essential.
