Brief Psychotic Disorder
Prevalence
Brief psychotic disorder is twofold more common in women than in men.
It may appear in adolescence or early adulthood, and onset can occur across the lifespan, with the average age at onset being the mid-30s.
Risk factors
Preexisting personality disorders and traits (psychoticism domain) may predispose the individual to the development of the disorder.
Symptoms
Delusions, hallucinations, disorganized speech (e.g., frequent derailment or incoherence).
Grossly abnormal psychomotor behavior, including catatonia.
Emotional turmoil or overwhelming confusion.
Impairment may be severe, supervision may be required.
An episode of the disturbance lasts at least 1 day but less than 1 month, and the individual eventually has a full return to the premorbid level of functioning.
