Disruptive Mood Dysregulation Disorder (DMDD): A New Diagnostic Approach to Chronic Irritability in Youth

摘要

Disruptive mood dysregulation disorder (DMDD) is a newcomer to psychiatric nosology. This new DSM-5 diagnosis addresses the need for improved classification and treatment of children exhibiting non-episodic irritability and severe temper outbursts. Currently, many of these children are diagnosed with bipolar disorder, despite the lack of distinct mood episodes. This diagnostic practice has raised concerns, in part due to the escalating prescription of atypical antipsychotics. This article provides an overview of the limited literature on DMDD including its history, and relevant studies of assessment and treatment. We include a case study to illustrate key points, including diagnostic issues that clinicians may encounter when considering a DMDD diagnosis.
