May be abrupt or insidious.

• A. Peak age of onset for men
• B. Onset of schizophrenia
• C. May be abrupt or insidious
• D. Depressive symptoms prevalence

Answer: (C)

Onset pattern for psychosis can vary a lot: it may appear abruptly over days to weeks, or develop insidiously with a gradual build of milder symptoms over months. An abrupt onset often brings into view florid psychotic features—delusions, hallucinations, or thought disorder—that rise quickly after a relatively normal period. An insidious onset, by contrast, might start with subtle changes like social withdrawal, reduced motivation, odd beliefs, or mood changes that slowly progress to full-blown psychosis. This variability matters clinically because a shorter duration of untreated psychosis (DUP) is linked to better outcomes, while a longer DUP—more common with insidious onset—can portend a tougher course. The statement that onset may be abrupt or insidious correctly captures this range of presentations, whereas the other ideas pertain to different epidemiologic facts (like peak age of onset) or are not about how onset occurs.
