Which form of schizophrenia can begin at any age and is often triggered by an emotionally traumatic event?

• A. Chronic Schizophrenia (Process Schizophrenia)
• B. Acute Schizophrenia (Reactive Schizophrenia)
• C. Catatonic Schizophrenia
• D. Schizophreniform Disorder

Answer: (B)

This question is testing how the onset pattern and triggering context differentiate forms of schizophrenia. The clue here is a sudden or abrupt appearance of symptoms that can occur at any age and is often precipitated by an emotionally traumatic event. This combination points to an acute, or reactive, course of schizophrenia. The trauma acts as a catalyst and the symptoms arise quickly, which contrasts with the more typical gradual development seen in chronic (process) schizophrenia, where the onset is insidious and progression is long-standing.

Catatonic schizophrenia is defined primarily by motor symptoms such as stupor, rigidity, or peculiar movements rather than by how or when the illness begins or what triggers it. Schizophreniform disorder resembles schizophrenia in symptoms but is distinguished by duration (a shorter course, typically less than six months) rather than by a trauma-triggered onset.
