Which symptom is associated with Neuroleptic Malignant Syndrome?

Neuroleptic Malignant Syndrome (NMS) is a serious and potentially life-threatening condition commonly associated with the use of antipsychotic medications. One of the hallmark symptoms of NMS is muscular rigidity, which refers to a severe increase in muscle tone leading to stiffness. This rigidity can affect various muscle groups and may be accompanied by other signs like elevated temperature, autonomic dysregulation, and altered mental status. The presence of muscular rigidity is critical in differentiating NMS from other conditions, especially in patients receiving neuroleptic medications.

The symptoms of NMS often arise in the context of medication changes or increased doses of antipsychotics, and muscular rigidity is one of the key clinical features that healthcare providers look for when diagnosing this syndrome. Understanding this symptom is vital for timely recognition and management of NMS, helping to prevent further complications.
