ICD-11 code : 6A23;
Preferred Label : Acute and transient psychotic disorder;
ICD-11 definition : Acute and transient psychotic disorder is characterised by acute onset of psychotic
symptoms that emerge without a prodrome and reach their maximal severity within two
weeks. Symptoms may include delusions, hallucinations, disorganisation of thought
processes, perplexity or confusion, and disturbances of affect and mood. Catatonia-like
psychomotor disturbances may be present. Symptoms typically change rapidly, both in
nature and intensity, from day to day, or even within a single day. The duration of
the episode does not exceed 3 months, and most commonly lasts from a few days to 1
month. The symptoms are not a manifestation of another medical condition (e.g. a brain
tumour) and are not due to the effect of a substance or medication on the central
nervous system (e.g. corticosteroids), including withdrawal (e.g. alcohol withdrawal).;
