Disruptive mood dysregulation disorder
Also known as DMDD · Severe mood dysregulation · Chronic irritability with temper outbursts · Temper dysregulation disorder
Fellowship guide to disruptive mood dysregulation disorder (DMDD): a DSM-5-TR diagnosis of severe, recurrent temper outbursts against a background of chronic, non-episodic irritability, created to curb paediatric bipolar overdiagnosis. Covers the criteria-clock of onset, duration and cross-setting impairment, the bipolar and ODD rule-outs, a behaviour-therapy-first stepped plan, when a stimulant or antidepressant is justified for comorbidity, and the Copeland, Benarous, Breaux and Zhang evidence.

Red flags
- Emerging manic symptoms — distinct elevated mood with decreased need for sleep, racing thoughts or grandiosity — this is bipolar disorder, not DMDD; stop and reassess before any antidepressant or stimulant
- Outbursts causing serious injury, dangerous aggression, or property destruction that cannot be contained safely at home — same-day specialist review and a safety plan, not a routine prescription
- Disclosed self-harm, suicidal ideation, or a depressive episode meeting full criteria — treat the mood disorder on its own terms and assess risk directly
- Disclosure or suspicion of abuse, neglect or family violence driving the behaviour — safeguarding comes before the diagnostic label
- Regression, focal neurology, cognitive decline or episodic confusion — search hard for an organic, neurological or substance cause rather than anchoring on behaviour

Overview & Definition
Picture the eight-year-old whose teacher says he "blows up" three or four times a week over a dropped pencil or a lost turn, whose explosions leave the classroom frozen, and who is still grouchy, snappy and easily annoyed for the rest of every day, at home and at school, and has been this way for over a year. That picture — frequent, disproportionate outbursts riding on a baseline of chronic irritability — is what you are looking for, not a single bad day or an isolated tantrum. [1] [11]
DMDD is a persistent, impairing disorder of mood dysregulation, not ordinary naughtiness and not a reaction in proportion to a small setback. The two ingredients are inseparable: the severe temper outbursts are the visible peaks, and the chronic, between-outburst irritable or angry mood is the defining baseline. Both must be there, and both must be there most of the day, nearly every day, in more than one setting, for at least twelve months. [11] [12]
Diagnosis is clinical and criteria-based, assembled from a multi-informant history (child, parent, school). Rating scales such as the Affective Reactivity Index support screening and tracking, but a high score never makes the diagnosis and never starts a drug. The label was introduced into DSM-5 specifically because too many chronically irritable children were being called bipolar and given antipsychotics — so the diagnosis carries its own built-in instruction: rule bipolar out first. [1] [3]
