Abstract
-
Neurologic complications such as mental status changes, incontinence, gait disturbances, extrapyramidal symptoms may be delayed days or weeks after exposure to carbon monoxide but hyperkinesia such as choreoballism and athetosis rarely occurs as symptoms of delayed neurologic complication of carbon monoxide intoxication. Neuroleptic malignant syandrome (NMS) is a rare, potentially fatal drug-induced disorder associated with hyperthermia, muscle rigidity, autonomic instability, mental dysfunction and various dyskinesia. Various major neuroleptic drugs seem to be its culprits. We describe a 24-year-old female patient who presented with NMS following administration of haloperidol for choreoballism, a symptom of delayed neurologic sequelas after carbon monoxide intoxication, with a review of the literature.
