Station brief
Format. Communication station, approximately 7–10 minutes after reading time. You are the psychiatry registrar. The patient is on the ward; you meet the partner. [1]
Candidate instructions. Explain what catatonia is in plain language, why it is treatable, the plan for a lorazepam trial and supportive care (fluids, clot prevention, monitoring), and a balanced explanation of ECT if needed. Avoid jargon dumps and invented legal section numbers. Check understanding and invite questions. [2][3]
Candidate scenario
Partner: “She won’t talk or move. Is this permanent brain damage? You’re talking about electric shocks — that sounds barbaric. Can’t you just force-feed her and wait?” Observations confirm mutism, posturing, and minimal intake. [1]
Marking domains
- Empathy and clear structure without defensiveness
- Accurate plain-language explanation of catatonia as a treatable psychomotor syndrome
- Rationale for lorazepam challenge/treatment
- Honest, non-catastrophising ECT explanation if non-response or danger
- Mention of medical support (hydration, VTE risk)
- Collaborative plan and check understanding [1][2][3]
Reveal assessor key
Open. Introduce role, acknowledge fear, sit, minimise interruptions. “I can see how frightening it is that she cannot speak or move — you are right to ask direct questions.” [1]
Explain catatonia. “We think she has catatonia — a serious but often highly treatable condition where the brain’s control of movement and speech freezes or becomes stuck. It can happen with severe depression and other illnesses. It is not the same as permanent brain death, and many people recover motor function with the right treatment.” [1][2]
What we are doing. “We will carefully examine her, check for medical causes, give fluids and prevent blood clots from lying still, and trial a medicine called lorazepam. A clear improvement after lorazepam supports the diagnosis and is also treatment. If she does not improve, or if she becomes medically unsafe from not eating and drinking, we may recommend ECT, which has strong evidence in catatonia.” [2][3]
ECT balance. “ECT uses a brief controlled seizure under anaesthetic. Temporary memory side effects can occur and we monitor them; for life-threatening catatonia the benefit often outweighs the risk. It is not a punishment and not ‘wiping the person away.’” [2][3]
Close. Summarise plan, invite questions, offer written information and named contact, document discussion. [1]
