<unk>  is generally diagnosed by the combination of unexpectedly high body temperature and a history that supports<unk>  instead of a fever. Most commonly this means that the elevated temperature has occurred in a hot, humid environment (heat stroke) or in someone taking a drug for which<unk>  is a known side effect (drug-induced<unk> . The presence of signs and symptoms related to<unk>  syndromes, such as extrapyramidal symptoms characteristic of neuroleptic malignant syndrome, and the absence of signs and symptoms more commonly related to infection-related fevers, are also considered in making the diagnosis. If fever-reducing drugs lower the body temperature, even if the temperature does not return entirely to normal, then<unk>  is excluded.
