DMDD
Also written as: DMDD — Disruptive Mood Dysregulation Disorder
Disruptive mood dysregulation disorder, characterized by chronic irritability and severe temper outbursts in children.
Full Definition
Disruptive mood dysregulation disorder is a childhood disorder characterized by severe and recurrent temper outbursts that are grossly disproportionate in intensity or duration to the situation. Between outbursts, the child's mood is persistently irritable or angry most of the day, nearly every day, and is observable by others. Symptoms must be present for at least 12 months, with no period longer than 3 consecutive months without symptoms. The disorder was introduced in DSM-5 to address concerns about overdiagnosis of bipolar disorder in children. Onset must be before age 10, though diagnosis cannot be made before age 6 or after age 18.
Usage
Usage note: Emphasize age restrictions and duration requirements in documentation.
