Abstract

Abstract : A 57-year-old man was admitted to a psychiatric ward in a confused state. He had a 30-year history of lately stable schizophrenia and antipsychotic medication had recently been reduced. The clinical picture was characterised by confusion, agitation, autonomic instability, muscle rigidity and elevated creatine kinase. Despite no other identifiable cause, physicians were reluctant to accept a diagnosis of neuroleptic malignant syndrome (NMS) due to the absence of fever. Despite acute renal failure, the patient was repeatedly transferred between medical and psychiatric wards; diagnosis and management were delayed, with potentially catastrophic consequences. NMS is a rare, life-threatening neurological disorder that can present atypically and requires emergency medical rather than psychiatric care. Clinicians must proactively distinguish between medical emergencies (including acute confusional states/delirium) and mental illness. Prompt, accurate diagnosis, management on the appropriate ward and effective teamwork between specialties are essential to improve patient outcomes in this potentially fatal condition.
