Schizophreniform and brief psychotic disorder — structured clinical viva

Working diagnosis. At 12 days, with abrupt onset after marked stressor and good premorbid function, the best DSM-facing working label is brief psychotic disorder (with marked stressor) — provisional until the episode fully remits within 1 month or the clock forces a longer label. Schizophrenia is premature. If symptoms continue past 1 month without yet reaching 6 months, revise toward schizophreniform. ICD framing may use ATPD language depending on the system specified.[1][2][4]

Good features. Abrupt onset, stressor colour, perplexity, non-blunted affect, good premorbid function — hopeful modifiers, not a reason to stop care.[1]

Why not schizophrenia today. Duration thresholds are part of the diagnosis. Twelve days cannot meet the multi-month schizophrenia duration construct; premature labelling causes stigma and exam failure.[1]

Acute care. Risk assessment, organic screen as indicated, continue FEP-style low-dose antipsychotic (e.g. risperidone already started — review dose, EPS, metabolic baseline), family psychoeducation, sleep and substance review, least-restrictive setting that is still safe.[3][6]

Family communication. “This is an acute psychotic episode. Today it fits a short-duration category, not a lifelong schizophrenia diagnosis. We treat seriously now, watch the next weeks carefully, and revise the name if the course changes. Many people recover fully; some later need longer-term spectrum care — follow-up decides.” Honesty about limited ATPD/brief-episode diagnostic stability over years without terrorising the family.[4][5][2]

Pitfalls. Withholding treatment because “it is only brief”; locking schizophrenia too early; missing organic disease; stopping tablets the day voices quiet without a relapse plan.[3][4]
