Neuroleptic malignant syndrome (NMS) is a rare but potentially fatal syndrome classically encountered in patients receiving typical antipsychotic agents. However, many physicians have also reported the occurrence of NMS with atypical antipsychotics, notably with atypical presentations. In this report, we present a case in which a patient's antipsychotic regimen during a psychotic episode (which involved both typical and atypical antipsychotics) subsequently led to NMS. During his stay, the patient developed an altered level of consciousness, elevation of creatine phosphokinase, hemodynamic instability, and a fever. However, the patient did not have signs of rigidity, the cardinal sign of this syndrome. The authors concluded that patients could develop NMS without rigidity while receiving an antipsychotic. Given this presentation, the authors suggest that clinicians have a high level of suspicion for NMS to avoid misdiagnosis and subsequent adverse consequences. Hence, clinicians must be vigilant about atypical presentations of NMS without rigidity.

Background: Neuroleptic malignant syndrome (NMS) is a rare yet potentially fatal iatrogenic syndrome that can manifest with life-threatening symptoms. Theorized to be caused by the dopamine-blocking effects of certain medications, such as antipsychotics, or the withdrawal of dopaminergic agents, NMS is characterized by hyperthermia, autonomic instability, altered mental status, and muscular rigidity. Most treated cases resolve within weeks; however, in some cases, residual catatonic symptoms can persist for months after the resolution of acute hyperthermic and hypermetabolic symptoms.

Background: Foreign language syndrome is a rare neuropsychiatric phenomenon typically following general anesthesia. To date, foreign language syndrome has not been associated with neuroleptic malignant syndrome (NMS) in the literature. This case aims to broaden the clinical understanding of NMS by presenting an atypical manifestation of foreign language syndrome and emphasizing the need for prompt recognition of such presentations for accurate diagnosis and management.

Background: Neuroleptic malignant syndrome (NMS) is a rare but potentially life-threatening adverse drug reaction. This study aims to identify the most prevalent drugs associated with the risk of NMS according to the United States Food and Drug Administration (FDA) Adverse Event Reporting System (FAERS) database.
Methods: Analyses were performed using data from the FAERS database from January 2004 to June 2024.

Background: Creatine kinase (CK) is an intracellular enzyme expressed most commonly in tissues such as skeletal muscle. CK can be used as an investigation to support the diagnosis of conditions such as neuroleptic malignant syndrome (NMS), a rare idiosyncratic drug reaction - classically to antipsychotic medications - which can be fatal. Routine screening of CK in psychiatric inpatients is a known practice, but its value is uncertain.

BACKGROUND Malignant hyperthermia (MH) and anesthesia-induced rhabdomyolysis (AIR) are rare, yet life-threatening complications that need prompt therapeutic actions and logistic preparedness for treatment success. Both conditions are triggered by general anesthetics, particularly volatiles and depolarizing muscle relaxants. In comparison with MH, which is an inherited pharmacogenomic disease of calcium channel receptor subpopulation and arises only after trigger exposure, AIR has been described mostly in patients with muscular dystrophies.
