Which statement best differentiates neuroleptic malignant syndrome from acute dystonia in terms of onset?

Explanation:
Onset timing differentiates these two conditions. Neuroleptic malignant syndrome tends to develop more slowly after starting or increasing a neuroleptic, typically over days and sometimes up to a week or more. Acute dystonia, in contrast, is an abrupt motor reaction to dopamine blockade that often appears within hours of exposure, especially with the first dose or a dose change. This means the statement best captures the difference: NMS has a slower onset, while acute dystonia occurs within hours.
