Review Comparative StudyIs neuroleptic malignant syndrome a neurogenic form of malignant hyperthermia?
Neuroleptic malignant syndrome is a rare and potentially lethal disorder associated with the use of antipsychotic medications. Heightened vigilance on the part of clinical providers has reduced morbidity and mortality caused by this disorder over the past decade, but there is still no consensus regarding its diagnosis, pathophysiology, or treatment. ⋯ Utilizing this conceptual framework, the author proposes that neuroleptic malignant syndrome may be caused by a spectrum of inherited defects in genes that are responsible for a variety of calcium regulatory proteins within sympathetic neurons or the higher order assemblies that regulate them. In this proposed model, neuroleptic malignant syndrome may be understood as a neurogenic form of malignant hyperthermia.
