Pediatric Bipolar Disorder: Challenges in Diagnosis and Treatment.

Despite an opportunity to prevent adult psychopathology associated with bipolar disorder through early diagnosis in children, there is insufficient information and awareness among healthcare providers about the unique features and treatment of mania and its comorbid conditions in children. Converging evidence from disparate sites describe a developmentally distinct presentation of bipolar disorder in youth that is highly morbid, persistent and responds to treatment with the mood stabilizer medications used in the treatment of adult bipolar disorder, such as divalproex sodium and carbamazepine. Some are additionally approved for use in pediatric populations including, for manic or mixed states, risperidone, aripiprazole, and asenapine for those aged 10-17 years and also including lithium and olanzapine for ages 13-17 years. Quetiapine is approved as monotherapy or as adjunct to lithium or divalproex sodium for manic states in those aged 10-17 years. Delayed or missed diagnosis, inappropriate treatment, worsening course, and treatment resistance unfortunately still occur. While an array of mood-stabilizing medications is available for treatment, such as second-generation antipsychotics, lithium, and anticonvulsants, these can be only partially effective and fraught with annoying and serious side effects. This article will review current practice in the diagnosis and treatment of pediatric bipolar disorder and its comorbid conditions, highlighting areas of need for future research.
