Explain autism diagnosis and irritability treatment to parents — CASC communication station

Target exams
Station brief
Format. Communication station, approximately 7–10 minutes active time after reading. You are the CAMHS psychiatry registrar in the neurodevelopmental clinic. [1]
Candidate instructions. Explain the autism spectrum diagnosis to the parents, outline supports that help, address whether medication treats core autism, discuss options if severe irritability continues after behavioural help, and check understanding and safety. The examiner plays both parents. [1]
Candidate scenario
Your patient, age 8, meets clinical criteria for autism spectrum disorder after multidisciplinary assessment. He has intense interests, needs routines, and struggles with peer play. Over the last term he has been hitting himself when overloaded. Parents ask: "Is this our fault? Is there a cure tablet? Will he ever go to mainstream school? What about those autism medicines online?" [1]
Marking domains
- Empathy, structure, agenda-setting; avoid blame
- Accurate plain-language explanation of social-communication + restricted/repetitive patterns
- Clear statement that no medicine treats core social-communication autism
- Description of educational, speech/OT, behavioural and parent supports; early intervention concept
- If discussing medicines: irritability indication only; name risperidone or aripiprazole class evidence; monitoring (weight/metabolic)
- Safety planning for self-injury; crisis contacts
- Checks understanding; offers written information and follow-up [1][2][3][4]
Reveal assessor key
Open. Thank them; name the time; ask main worries first. Explicitly reject parental blame — autism is a neurodevelopmental difference with strong genetic contribution, not caused by cold parenting or vaccines.[1]
Explain ASD. "Autism spectrum means lasting differences in how he connects socially and communicates, together with strong need for sameness, intense interests or sensory differences. It is a spectrum of support needs, not a single path." Avoid saying he will never achieve anything; be honest that needs vary and supports matter.[1]
What helps. School adjustments, speech and occupational therapy, structured routines, parent strategies. Early developmental programmes (e.g. ESDM-type approaches in younger children) have trial evidence for improving developmental outcomes — frame hope through support intensity, not magical cure.[4]
Medicines. "There is no tablet that removes autism itself. If severe aggression or self-injury continues after behavioural and medical checks, medicines such as risperidone or aripiprazole can reduce irritability for some children, but they need blood pressure/weight/metabolic monitoring and are used carefully."[2][3]
School. Many children access mainstream with adjustments; some need more specialised settings — decision is individual, not automatic exclusion.[1]
Close. Summarise, invite questions, safety-net for escalating self-injury, written leaflet, review date. [1]
