What is characterized by psychosis that lasts from one day to one month, followed by a complete return to baseline?

• A. Schizophrenia
• B. Brief Psychosis
• C. Delusional Disorder
• D. Bipolar Disorder

Answer: (B)

The condition characterized by psychosis lasting from one day to one month, followed by a complete return to baseline functioning, is brief psychosis. This disorder is typically marked by the sudden onset of delusions, hallucinations, disorganized speech, or grossly disorganized or catatonic behavior. Importantly, those experiencing brief psychosis return to their previous level of functioning after the episode has resolved, which distinguishes it from other psychotic disorders that might not afford such a complete return to baseline. In contrast, schizophrenia involves more chronic symptoms that persist for at least six months. Delusional disorder is characterized by the presence of one or more delusions that persist for at least one month, but it does not include the acute psychotic symptoms or the short duration typical of brief psychosis. Bipolar disorder may involve psychotic features, but it is primarily defined by mood episodes, and the psychosis can occur in the context of major depressive or manic episodes rather than a standalone duration as seen in brief psychosis.
