What is the maximum duration of symptoms in a brief psychotic disorder?

In a brief psychotic disorder, the maximum duration of symptoms is specified as one month. This condition is characterized by a sudden onset of psychotic symptoms, such as delusions, hallucinations, disorganized speech, or grossly disorganized or catatonic behavior. Importantly, these symptoms must last for at least one day but less than one month. If the symptoms persist for more than a month, the diagnosis might change to a different psychotic disorder, such as schizophrenia or schizoaffective disorder, depending on the presence and duration of other symptoms. This time frame is crucial because it helps differentiate brief psychotic disorder from other disorders with more persistent symptoms.
