Schizophrenia spectrum and other psychotic disorders
Brief Psychotic Disorder
Brief psychotic disorder is a sudden episode of clear psychotic symptoms lasting at least one day but less than one month, followed by an eventual full return to the previous level of functioning.
Brief does not mean harmless
Symptoms may include delusions, hallucinations, disorganised speech or markedly disorganised or catatonic behaviour. At least one present symptom must be delusions, hallucinations or disorganised speech.
A first or sudden psychotic episode may have medical, neurological, medication-related or substance-related causes. The final diagnosis often becomes clear only after the course has been observed over time.
Assessment
- Onset is described as sudden when the change from a non-psychotic state to clear psychosis occurs within two weeks, although non-specific changes may have appeared earlier.
- Culture, language and religious context are considered before a belief or experience is classified as psychotic.
- Clinicians assess mood episodes, delirium, substances, medicines, neurological conditions, safety and capacity for basic self-care.
Treatment
Same-day assessment, a calm low-stimulation setting and clear communication are priorities. Aggressive arguments about whether an experience is ‘real’ can increase fear.
A psychiatrist may use antipsychotic medication for a limited period, and hospital care may be necessary for severe risk, catatonia, extreme agitation or inability to meet basic needs. Follow-up supports sleep, functioning, family understanding and early recognition of recurrence.
When urgent help is needed
Every first presentation of delusions, hallucinations, severe disorganisation or catatonia needs same-day professional assessment. Suicide risk, serious self-harm, immediate threats, seizures, suspected overdose, severe confusion or inability to eat or drink is an emergency.
