Which of the following is NOT a symptom of Neuroleptic Malignant Syndrome (NMS)?

• A. Stiffness
• B. Pain in the chest
• C. Pyrexia
• D. Autonomic instability

Answer: (B)

Neuroleptic Malignant Syndrome (NMS) is a potentially life-threatening condition usually associated with the use of antipsychotic medications. The hallmark symptoms of NMS include severe muscle rigidity or stiffness, high fever (pyrexia), and autonomic instability such as changes in blood pressure, heart rate, and sweating. Chest pain is not a recognized symptom of NMS. While patients experiencing NMS might report discomfort or sensations related to their overall condition, such as anxiety or distress, chest pain specifically is not commonly associated with this syndrome. The presence of stiffness, pyrexia, and autonomic instability aligns with the well-established clinical picture of NMS, whereas chest pain does not fit within the core symptoms of this syndrome.
