Chronically irritable mood with frequent temper outbursts
Disruptive mood dysregulation disorder (DMDD) is a new diagnostic addition to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5). The core feature of the disorder is chronic, severe, and persistent irritability that manifests as frequent temper outbursts that are inconsistent with the patient’s developmental level. The temper outbursts can be verbal or behavioral including physical aggression or property destruction. Between outbursts, the child remains persistently irritable or angry for most of the day, nearly every day. These symptoms persist across time and settings and are easily observable by others. Psychotherapeutic interventions including parent training and individual psychotherapy are critical components of a comprehensive treatment plan. Since DMDD is a new diagnosis, there are no published randomized controlled medication trials. The use of selective serotonin reuptake inhibitors (SSRIs) or second-generation antipsychotics may be considered for decreasing irritability.
