Disruptive mood dysregulation disorder
Summary
Disruptive mood dysregulation disorder (DMDD) is a mental disorder in children and adolescents characterized by a persistently irritable or angry mood and frequent temper outbursts that are disproportionate to the situation and significantly more severe than the typical reaction of same-aged peers. DMDD was added to the DSM-5 as a type of depressive disorder diagnosis for youths. The symptoms of DMDD resemble those of attention deficit hyperactivity disorder (ADHD), oppositional defiant disorder (ODD), anxiety disorders, and childhood bipolar disorder .
DMDD first appeared as a disorder in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) in 2013 and is classified as a mood disorder. Treatments include medication to manage mood symptoms as well as individual and family therapy to address emotion-regulation skills. Children with DMDD are at risk for developing depression and anxiety later in life.
Children with DMDD show severe and recurrent temper outbursts three or more times per week. These outbursts can be verbal or behavioral. Verbal outbursts often are described by observers as "rages", "fits", or "tantrums". Children may scream, yell, and cry for excessively long periods of time, sometimes with little provocation. Physical outbursts may be directed toward people or property. Children may throw objects; hit, slap, or bite others; destroy toys or furniture; or otherwise act in a harmful or destructive manner.
Children with DMDD also display persistently irritable or angry mood that is observable by others. Parents, teachers, and classmates describe these children as habitually angry, touchy, grouchy, or easily "set off". Unlike the irritability that can be a symptom of other childhood disorders, such as ODD, anxiety disorders, and major depressive disorder, the irritability displayed by children with DMDD is not episodic or situation-dependent. In DMDD, the irritability or anger is severe and is shown most of the day, nearly every day in multiple settings, lasting for one or more years.
