Explain a first episode of psychosis to a young person and family — OSCE

OSCE communication station: explaining a first episode of psychosis as a treatable medical illness, the duration-of-untreated-psychosis rationale for prompt specialist referral, first-line antipsychotic treatment and metabolic monitoring, and cannabis as a modifiable risk factor, framed without blame.

Prompt
Parents of a 15-year-old boy with a first episode of psychosis — persecutory beliefs, auditory hallucinations and sleep loss after daily high-potency cannabis use — ask whether the illness is real, whether they or cannabis caused it, what the treatment is, what the tablets will do to him, and how he will be monitored, after medical causes have been excluded.

Candidate instructions

Explain that a first episode of psychosis is a real and treatable medical illness, not a character flaw or a parenting failure; describe why prompt specialist referral matters through the duration-of-untreated-psychosis idea in plain terms; outline first-line antipsychotic treatment and what the medication will and will not do; address cannabis as a modifiable risk factor without blame; describe the metabolic monitoring plan; check understanding; and agree a shared written plan. The examiner plays a parent. [2] [4]
