What symptom is indicative of Neuroleptic Malignant Syndrome (NMS) related to blood pressure?

Labile blood pressure is a significant symptom indicative of Neuroleptic Malignant Syndrome (NMS), a rare but serious reaction to antipsychotic medications. In NMS, patients may experience fluctuations in blood pressure that can vary rapidly, which is characteristic of labile blood pressure. This instability can occur due to the autonomic dysregulation and severe central nervous system disturbances that happen during the syndrome.

These fluctuations might be accompanied by other symptoms such as high fever, altered mental status, muscle rigidity, and elevated creatine kinase levels. The presence of labile blood pressure signifies the need for immediate medical intervention, as NMS can progress quickly and may escalate to life-threatening conditions. Understanding this symptom is crucial for nurses and healthcare providers in identifying and managing NMS effectively.
