Which disorder is likely to have an acute onset preceded by high stress?

• A. Schizophrenia
• B. Schizophreniform disorder
• C. Delusional disorder
• D. Brief psychotic disorder

Answer: (B)

Onset pattern helps distinguish psychotic disorders. When symptoms appear abruptly and are linked to a significant stressor, the diagnosis often points to a condition that has a rapid, but not necessarily ultra-brief, course. Schizophreniform disorder fits this well: it involves schizophrenia-like symptoms (delusions, hallucinations, disorganized thinking) with a duration typically between one and six months, and the onset can be abrupt or acute, especially in the context of a stressor. That combination of an abrupt start and a duration longer than a brief episode makes it the best match for the scenario. Schizophrenia, by contrast, requires a longer course (six months or more) and isn’t defined by an acute, stress-related onset. Delusional disorder centers on persistent delusions without prominent disorganized thinking or marked affective disturbance, and it doesn’t usually present with an abrupt psychotic break after stress. Brief psychotic disorder does have abrupt onset after a major stressor, but the symptoms last only a short time (typically less than a month), which distinguishes it from the situation described here.
