Explain disruptive mood dysregulation disorder to parents — OSCE

Candidate instructions

You are the paediatric registrar. The parents of an eight-year-old boy with severe temper outbursts three to four times a week and a chronically irritable mood at home and school for over a year have ten minutes with you. They have read online that he might be bipolar and want medication to calm him down. Explain, in plain language: (1) what disruptive mood dysregulation disorder is and why it is a treatable mood-dysregulation condition; (2) why this is not bipolar disorder and how you excluded it; (3) how parent training and emotion-regulation therapy work and why they come first; and (4) when a medicine is genuinely justified and why a sedating drug is not the routine first step. Invite their questions and agree a shared plan. Do not lecture; check understanding throughout. ^[1]
