He displayed disorganized speech and believed that the books were the only way to his salvation. Identification was found on the man and his sister was called to provide more information. She described that he recently lost his house and got divorced within the same week although he seemed fine three days ago. The man was sedated with diazepam and chlorpromazine because he was very agitated. His labs returned normal and within three days, he appeared normal, had no recollection of the past several days, and discussed in detail how stressful the past two weeks of his life were. He was discharged the next day. Which of the following is the most appropriate diagnosis for this male?? A: Brief psychotic disorder, B: Schizophreniform disoder, C: Schizophrenia, D: Schizoid personality disoder, E: Schizotypal personality disoder,  <response>: This question describes a 55-year-old male exhibiting psychotic symptoms like disorganized speech, delusions, and inappropriate public behavior. The symptoms emerged suddenly in the context of recent significant stressors - losing his house and getting divorced within the same week. The symptoms resolved within a few days with sedation and antipsychotic medications. The description is most consistent with brief psychotic disorder. This diagnosis requires the sudden onset of psychotic symptoms like delusions, hallucinations, disorganized speech, and grossly disorganized or catatonic behavior, in the absence of a prior psychotic disorder. The symptoms must resolve within 1 month. The symptoms often follow a stressful life event, as in this case. Schizophrenia is less likely as it requires at least 6 months of active symptoms. Schizophreniform disorder requires symptoms between 1-6 months, which does not fit this case where symptoms resolved within days. Schizotypal and schizoid personality disorders are chronic pervasive conditions, not acute psychotic episodes.A: Brief psychotic disorder
