An afebrile neuroleptic malignant syndrome with hyponatremia: A case report.

Abstract

Neuroleptic malignant syndrome (NMS) is a rare, life-threatening situation in response to the adverse reaction of antipsychotic medications characterized by high-grade fever, altered Glasgow coma scale, autonomic dysfunction, and stiffness. We herein present a case with a typical presentation of stiffness and autonomic dysregulations along with the atypical symptoms of urinary incontinence and a history of falls. The patient was afebrile with hyponatremia, showing a similar presentation diagnosed as NMS and treated successfully according to the hospital protocol.
