Six Weeks of Withdrawal, a Voice, and a Family That Wants Silence
A 24-year-old Kuwaiti man is brought to the outpatient clinic by his father. Over six weeks he has stopped attending university, sleeps 13-14 hours, eats little, and is heard muttering alone at night. He says the neighbours have worked sihr (sorcery) against him and that a voice comments on his prayers. He denies prior psychiatric contact and denies current drug use, but admits daily hashish until two months ago and two occasions of 'captagon' (amphetamine) three months ago. There is no history of elevated mood, reduced need for sleep, or antidepressant treatment. His maternal uncle had an episode at 22 and recovered on medication. On examination he is guarded, with blunted affect and no clear depressive syndrome; a urine drug screen today is negative. His father, a retired teacher, asks that nothing be written in the file because the family fears stigma and wants a traditional healer involved first. He refuses to discuss medication.
1. Construct a working differential diagnosis and identify the three pieces of information that would most change the ranking. Explain how the duration criterion changes the label you would use under ICD-11/ICD-10 versus DSM-5-TR.

Differential, ranked
- First-episode schizophrenia-spectrum disorder: six weeks of functional collapse, blunted affect, auditory verbal hallucination with a commenting quality, family history in a first-degree relative.
- Substance-induced psychotic disorder: cannabis and amphetamine are both plausible; a single negative urine screen excludes nothing, since cannabis metabolites clear over days to weeks and the relevant exposure was months ago.
- Psychotic disorder due to another medical condition: subacute onset with muttering and withdrawal warrants thyroid function, B12, syphilis/HIV serology, electrolytes, and EEG or neuroimaging if any focal sign, seizure history, or atypical course appears.
- Mood disorder with psychotic features: currently unlikely, since no sustained mood episode is described, but must be re-checked longitudinally.
- Brief psychotic disorder: excluded by duration.
Why duration matters At six weeks the two manuals diverge. DSM-5-TR requires six months of continuous disturbance (with one month of active symptoms), so the honest DSM label today is schizophreniform disorder. ICD-10 and ICD-11 require roughly one month of core symptoms, so schizophrenia is already permissible. Because MOH records are coded to ICD, state explicitly which system you are using and record the label as provisional and time-limited; this protects the patient's file and your reasoning if the picture evolves.
The three most decisive facts (a) Premorbid trajectory - good premorbid function with abrupt decline favours a remitting psychosis; long-standing social withdrawal and oddness before the hashish favours schizophrenia. (b) Corroborated substance timeline plus observed abstinence - a collateral history from a friend and, where available, hair testing, tells you whether abstinence preceded the symptoms. (c) The medical screen - a positive finding reclassifies the case entirely. Collateral from the university and a second interview with the father should be gathered in parallel, not deferred.
2. You must decide whether to start antipsychotic medication at this visit, given diagnostic uncertainty and the family's resistance. Set out your reasoning, including how you will handle the sihr explanation and the father's request for no written diagnosis.

Should you treat now? Yes, in most cases. Six weeks of untreated psychosis with loss of study and social role is a modifiable harm: longer duration of untreated psychosis predicts worse functional outcome, and diagnostic uncertainty is not a reason to withhold treatment. What uncertainty should change is the label, the dose and the monitoring plan, not the decision to act.
Concretely: baseline weight, waist, blood pressure, HbA1c or fasting glucose, lipids, prolactin, and ECG if cardiac risk; start a low-dose second-generation antipsychotic; write 'provisional psychotic disorder, aetiology under evaluation' with a review date at two weeks; book the medical screen and the collateral interview; give clear red-flag advice (fever, stiffness, confusion, sedation) and a crisis number.
Handling sihr Treat the explanation as an explanatory model, not as a competing diagnosis. Ask what the healer has advised, whether any treatment has been prescribed, whether food or medication has been restricted, and whether the family believes hospital treatment will worsen it. Then negotiate a shared frame: 'the harm is real - he has lost his studies and his sleep; we will treat the body and the social consequences, and you may continue what is spiritually meaningful to you as long as it does not replace or delay this.' Do not mock the belief and do not collude with it. A trusted elder or an imam known to the family can be an ally in adherence.
The father's request You can be discreet - limit who has access, avoid gratuitous detail, use neutral wording - but you cannot falsify or omit a diagnosis that determines treatment. Explain this plainly, in Arabic, with the son's consent for the father's involvement. Record the conversation, the risks discussed, the patient's own view, and the follow-up plan. If the son refuses medication and retains capacity, document that, offer psychoeducation and harm reduction, and keep the door open.
3. The father asks, 'Is this because of the evil eye, or is my son ill?' and adds that a cousin with the same problem was 'cured' in a week without medication. How do you respond, and what do you document?

Answer the question he actually asked rather than dismissing it. A workable structure is: validate, differentiate, offer a testable plan.
Validation: 'You are not wrong to look for a spiritual cause; many families here do, and I am not going to tell you your faith is mistaken.' Differentiation: 'What concerns me is the part that can be measured - he has stopped studying, sleeps fourteen hours, hears a voice that comments on him, and has lost weight and routine. Those are signs of a brain and body problem that also needs treatment.' Testable plan: propose a short, time-bound trial ('give me six weeks of treatment alongside whatever spiritual support you value, and we will judge it on sleep, attendance, and the voice, not on opinion'), and set a review date so the family is not surrendering to an open-ended commitment.
On the cousin: 'One case cannot tell us what will work for your son. Some people recover quickly; some relapse without treatment. That is exactly why we watch him closely rather than guess.' This is also a gentle correction of the base-rate error without humiliating the father.
Documentation must include: the explanatory model as reported; the family's preference for traditional care and any healer-prescribed treatment; the psychoeducation given, in what language, and with whom; the negotiated plan and review date; the risks of untreated psychosis and of medication discussed; the patient's capacity and his consent or refusal. Documenting the belief is not endorsing it, and it protects both continuity of care and you, if the family later disputes what was said.
