Station brief
Format. Communication station, approximately 7–10 minutes after reading. You are the psychiatry registrar in outpatient clinic. [1]
Candidate instructions. Validate the patient’s experience, explain that the story fits a sleep–wake brain disorder (likely narcolepsy with cataplexy) rather than laziness, outline why PSG/MSLT is needed, give clear driving/work safety advice after a near-miss, and preview evidence-based treatments (scheduled naps, wake promoters such as modafinil-class agents, anticataplexy options) without promising an immediate unrestricted return to night driving. Check understanding. The examiner plays the patient. [1][2][3]
