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 syndrome (NMS) is a rare, potentially fatal drug-induced disorder associated with hyperthermia, muscle rigidity, autonomic instability, mental
dysfunction
and varrious dyskinesia. Various major neuroleptic drugs seem to bc 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 sequelae
after
carbon monoxide intoxication, with a review of the literature.
