The goal of the Pediatric Bipolar Registry (PBR) is to provide a comprehensive assessment regarding the diagnosis and treatment of pediatric bipolar disorder to children and adolescents with any current mood state and/or children/adolescents who are offspring of a parent with bipolar disorder (BD) type I or II and their families.

Data collected will be utilized to perform a retrospective chart review to include measure outcomes and de-identified demographic information detailed in the attached case report forms. In each case where a diagnosis of bipolar disorder I, bipolar disorder II, or bipolar disorder NOS is determined, the child/adolescent will be added to the PBR and provided with information about local providers that are qualified to treat their diagnosis. Each subject can elect to be notified about future research studies s/he may qualify for. Furthermore, the investigators will provide ongoing newsletters with useful information that addresses the latest research underway in the field with the families. If requested, the investigators will provide a written report to their current provider detailing our evaluation. The potential for a breach in confidentiality always exists; however, information that is obtained will be stored in password a protected database and locked file drawers in locked offices; data will have identifying information sheered from it to prevent loss of confidentiality, and all staff must sign confidentiality certificates. If child abuse is detected, the research team is obligated to follow mandatory state reporting laws. To the investigators' knowledge, there is no registry for Pediatric Bipolar Disorder in the city of Houston or the state of Texas that provides the comprehensive evaluation that we are proposing for these children and adolescents and their families. Therefore, this will be a novel service within this division that will provide research to families and potential clients for providers managing these families across the State of Texas.
