Neuroleptic malignant syndrome

Summary of Neuroleptic malignant syndrome
Neuroleptic malignant syndrome is a life-threatening neurological disorder most often caused by an adverse reaction to neuroleptic or antipsychotic drugs. The syndrome typically consists of muscle rigidity, fever, autonomic instability, and cognitive changes such as delirium, and is associated with elevated plasma creatine phosphokinase. The incidence of neuroleptic malignant syndrome has decreased since it was first described, due to changes in prescribing habits, but it is still a potential danger to patients being treated with antipsychotic medication. Because of the unpredictability of neuroleptic malignant syndrome, treatment may vary substantially, but is generally based on supportive care and removal of the offending antipsychotic drug.
