Tragedy of a Catatonia Preceding and Complicating a Neuroleptic Malignant Syndrome

Catatonia is a complex psychomotor syndrome characterized by a range of motor, behavioral, and autonomic abnormalities. While commonly associated with psychiatric disorders, particularly schizophrenia, catatonia can also result from non-psychiatric etiologies. Malignant catatonia is a rare and life-threatening form of the syndrome that can overlap clinically with neuroleptic malignant syndrome (NMS), particularly when precipitated by antipsychotic treatment. We present the case of an 18-year-old male with no psychiatric history who developed catatonic symptoms and was mistakenly treated with antipsychotics, leading to the onset of NMS. After stabilization in intensive care, he was diagnosed with catatonia and treated with benzodiazepines and Amisulpride but ultimately succumbed after 15 days of hospitalization. This case highlights the diagnostic challenges in distinguishing between malignant catatonia and NMS, as both conditions may share clinical features and may respond to similar treatments such as benzodiazepines and electroconvulsive therapy (ECT). The case underscores the critical importance of early recognition and appropriate intervention to prevent fatal outcomes. Delayed or inappropriate treatment significantly increases the risk of complications including thromboembolism, dehydration, and organ failure. ECT, when administered early, is associated with better prognosis. Our case reinforces the need for heightened clinical awareness and prompt multidisciplinary management.
