Diagnostic and therapeutic challenges in neuroleptic malignant syndrome: a severe medical case.

Neuroleptic malignant syndrome (NMS) is a rare, idiosyncratic medical emergency usually associated with the use of dopamine antagonists, commonly typical antipsychotic drugs. However, it has been observed that it can occur with atypical antipsychotics as well. NMS is characterized by altered consciousness, fever, rigidity, autonomic instability and high creatine phosphokinase (CPK) blood levels.
