Explain early-onset psychosis care to parents — CASC communication station · Psych CASC / OSCE

Prompt

Parents of a 15-year-old with early-onset psychosis want a plain-language explanation of diagnosis, medical checks, medication and metabolic risk, cannabis, school, and what happens if the first tablet does not work.

Station brief

Format. Communication station, approximately 7–10 minutes active time after reading. You are the CAP psychiatry registrar in the youth early intervention / CAMHS clinic. [1]

Candidate instructions. Explain the working diagnosis of early-onset psychosis to the parents, outline medical checks and treatment (medication and psychosocial including school), discuss metabolic monitoring and cannabis, address what happens if the first medication does not work, and check understanding. The examiner plays both parents. [1]

Candidate scenario

Your patient, age 15, has a working diagnosis of early-onset psychosis after medical exclusion is underway. You plan to start a low-dose antipsychotic after baseline bloods and ECG.[1][2] He uses cannabis most weekends. Parents ask: "Is this schizophrenia forever? Will the drugs make him obese and diabetic? Should we pull him out of school permanently? What if the first tablet fails?" [1]

Marking domains

Empathy, structure and agenda-setting
Accurate plain-language explanation of EOP as a pathway (not day-one lifelong fatalism)
Clear description of multi-element care including family and school
Medication purpose, common side-effects (e.g. akathisia, metabolic risk) and monitoring
Why early treatment matters (DUP)
Cannabis counselling without blame
Honest clozapine/threshold language if two adequate trials fail — without scaring them into non-engagement
Checks understanding and safety-net [1][2][3][4]

Reveal assessor key

Open. Thank them; name the time; ask main worries first. [1]

Explain EOP. "Early-onset psychosis means a break from shared reality — for example fixed false beliefs and hearing a voice commenting — severe enough to affect school and relationships, starting before 18. Some young people recover substantially with early multi-element care; others need longer treatment. We avoid saying 'this is schizophrenia forever' on day one while still treating seriously." [1][4]

Explain care package. Medication reduces intensity of positive symptoms for many people; we start at a low dose and monitor closely. Weight, blood sugar and lipids matter because young people can gain metabolic risk early after antipsychotics — we measure from the start, not after a crisis.[2] We also offer family education, talking treatments, sleep and routine support, school liaison so education continues with adjustments, and help with cannabis. [1]

DUP. Longer time untreated links to poorer outcomes — seeking help now matters.[4]

If first tablet fails. We try an adequate trial (right dose, enough weeks, taking it as agreed). If two proper trials fail, a medicine called clozapine has the best evidence in hard-to-treat early-onset schizophrenia — it needs special blood monitoring, and we would discuss that carefully then, not as a day-one scare.[3]

School. May need temporary adjustment, not automatic permanent removal; recovery includes learning and roles. [1]

Close. Summarise, invite questions, crisis contacts, written info, review plan. [1]
