Psych · Child and adolescent psychiatry — chronic irritability / DMDD
Disruptive mood dysregulation disorder
Also known as DMDD · Severe mood dysregulation · SMD · Chronic severe irritability children · Pediatric chronic irritability · Temper outbursts mood disorder · Nonepisodic irritability youth
Exam-exhaustive fellowship reference on disruptive mood dysregulation disorder — DSM-5-TR criteria and age rules, SMD historical construct, Copeland epidemiology and adult outcomes, multi-informant assessment, bipolar/ODD/ADHD differentials and hierarchy, psychosocial first-line care (parent training, Waxmonsky group therapy, DBT-C), medication limits (Dickstein lithium-negative; Towbin citalopram+stimulant signal), school and safeguarding, FRANZCP/MRCPsych/ABPN framing. Distinct from ODD/CD, youth depression, and bipolar topics.

Red flags
- Imminent severe aggression, weapons access, or school/community safety risk — de-escalate, restrict means, multiagency safety plan; medication is not a safeguarding plan
- Distinct manic/hypomanic episode features (decreased need for sleep, grandiosity, episodic elevated mood) — do not force a DMDD label; re-enter bipolar pathway
- Safeguarding concerns (abuse, neglect, domestic violence) hidden under 'behaviour problems' — escalate child-protection pathways
- Polypharmacy framed as 'pediatric bipolar treatment' for nonepisodic chronic irritability without manic episodes — reformulate and simplify
- New activation, suicidality, or self-harm after starting an SSRI adjunct — same-day risk review and intensity escalation
- Preschool-only tantrums labelled DMDD before developmental and age-floor rules are applied
Meet the patient
A nine-year-old girl has a meltdown over the wrong colour cup — three times this week. Between the explosions she is cranky, touchy and angry for most of every day, at home and at school, and has been for over a year. She sleeps badly and has no friends left. Her parents are exhausted and afraid.[4][13]
The registrar's first sentence is "paediatric bipolar". The examiner's question stops that cold: "Is this mania, or is this the nonepisodic irritability pathway — and what would you do differently?" DMDD exists precisely to answer that question.[1][15]
