Can Neutrophil-Lymphocyte Ratio Be a Useful Criterion for Neuroleptic Malignant Syndrome in the Absence of Leukocytosis?

Objective: Neuroleptic malignant syndrome (NMS) is a rare but severe side effect of antipsychotic medication. Neutrophil-lymphocyte ratio (NLR) is a simple marker used to measure systemic inflammation. Method: In this case report we explore the relationship of inflammation in the etiology of NMS. In our case involving NMS, although there was no leukocytosis, the NLR was increased up to systemic infection levels. Conclusion: We hypothesized that systemic inflammation may take a role in developing NMS. If so, NLR could be a new marker of NMS that may be able to provide more sensitive results than leukocyte levels.
