    A 55-year-old woman with a history of bipolar affective disorder developed hyperpyrexia, rigidity and depressed consciousness (neuroleptic malignant syndrome) after commencing neuroleptic therapy.

Neuroleptic malignant syndrome needs both early recognition and prompt treatment to obviate devastating complications.
