Correct answer: C — Hypoactive delirium

Hypoactive delirium presents with reduced alertness, withdrawal and poor attention, and is easily mistaken for depression or dementia. The acute change during infection favours delirium rather than a primary mood disorder. Hypoactive delirium carries significant risk because it is often under-recognised.
