The Neuroleptic Malignant Syndrome (NMS) is a medical emergency of infrequent presentation in the emergency department, which is associated with the use of psychiatric drugs, such as typical and atypical antipsychotics. Our case addresses a 55-year-old patient diagnosed with undifferentiated schizophrenia for 10 years, who had been receiving clozapine and clonazepam as part of their treatment. This patient presents the symptoms of Neuroleptic Malignant Syndrome without fever, which improves with treatment especially with the withdrawal of clozapine...

BACKGROUND: A recent large database analysis raised concerns of potential acute kidney injury (AKI) risk associated with antipsychotics. However, whether individual atypical and typical antipsychotics are associated with differential AKI risks has not been investigated. OBJECTIVE: The current study compared the risks of AKI and known causes of AKI associated with a broad range of atypical and typical antipsychotics. METHOD: This retrospective cohort analysis used January 2007-June 2013 US nationwide Humana claims data to define episodes of antipsychotic drug therapy for patients with schizophrenia and bipolar disorder...

Malignant catatonia (MC) is a life-threatening manifestation which can occur in the setting of an underlying neuropsychiatric syndrome or general medical illness and shares clinical and pathophysiological features and medical comorbidities with the Neuroleptic Malignant Syndrome (NMS). The subsequent diagnosis and definitive therapy of MC are typically delayed, which increases morbidity and mortality. We present two cases of MC and review recent literature of MC and NMS, illustrating factors which delay diagnosis and management...

OBJECTIVE: To examine sex and age distributions in neuroleptic malignant syndrome (NMS) patients based on a systematic literature review. METHOD: EMBASE and PubMed databases were searched to identify any observation of NMS published from January 1, 1998 through November 1, 2014 that was accessible and interpretable (using language translation software). Redundant and equivocal reports were excluded. Sex ratio and age distributions were examined using standard graphical techniques and measures of association...

Neuroleptic malignant syndrome is an unpredictable iatrogenic neurologic emergency condition, mainly arising as an idiosyncratic reaction to antipsychotic agent use. It is characterized by distinctive clinical features including a change in mental status, generalized rigidity, hyperpyrexia, and dysautonomia. It can be lethal if not diagnosed and treated properly. Mortality and morbidity attributed to this syndrome have recently declined markedly due to greater awareness, earlier diagnosis, and intensive care intervention...

Cho-Hsiang Yang, Ying-Yeh Chen
Olanzapine, a frequently used second-generation antipsychotic, has rarely been implicated as a cause of drug-induced fever in the absence of neuroleptic malignant syndrome. We describe a patient who developed isolated fever following olanzapine monotherapy, which subsided after discontinuation of olanzapine. Blockade of dopaminergic receptors and elevated cytokines concentration are possible mechanisms of fever development during treatment with olanzapine. This case calls for attention to olanzapine-induced fever in clinical practice...

Neuroleptic malignant syndrome (NMS) is a life-threatening idiosyncratic reaction that usually occurs after the administration of antipsychotic drugs. Antidepressants, benzodiazepines, and antiepileptic drugs are also suggested to be associated with NMS. It is believed to result from a dopaminergic blockade in the central nervous system. NMS is manifested by hyperthermia, muscle rigidity, autonomic dysfunction, altered mental status, leukocytosis, and elevated serum creatinine phosphokinase. Valproate is commonly used in the treatment of many psychiatric and neurologic disorders...

Neuroleptic malignant syndrome (NMS) is a rare but potentially fatal complication of the use of certain medications. It is being seen more often in the pediatric population because of the increasing use of both typical and atypical antipsychotics in children. Rapid recognition of NMS is important to emergency physicians because timely treatment can be life saving. Acute dystonia is also a well-known and more common adverse effect of certain types of antipsychotics, more commonly seen with the typical antipsychotics versus the atypical antipsychotics...

BACKGROUND: Neuroleptic malignant syndrome requires prompt recognition for effective management, but there are no established diagnostic criteria. This is the first validation study of recently published international expert consensus (IEC) diagnostic criteria, which include priority points assigned on the basis of the importance of each criterion for making a diagnosis of neuroleptic malignant syndrome. METHODS: Data were extracted from 221 archived telephone contact reports of clinician-initiated calls to a national telephone consultation service from 1997 to 2009; each case was given a total priority point score on the basis of the IEC criteria...

OBJECTIVES: Severe agitation is a common symptom in pediatric cases of anti-N-methyl-D-aspartate receptor (anti-NMDAR) encephalitis-an autoimmune encephalitis with prominent neuropsychiatric symptoms. Agitation is a major barrier to treatment of the underlying disease process and increases patients' risk of harming themselves and others. Furthermore, male patients often have undetectable tumors and are especially at risk for extended hospitalization, but have been infrequently studied...

Chih-Wei Hsu, Yu Lee, Chun-Yi Lee, Pao-Yen Lin
BACKGROUND: Combination lithium, a mood stabilizer, and risperidone, an atypical antipsychotic drug, is widely used for treatment of psychotic disorders. Rare reports concern severe adverse drug reaction in multiple organic systems with their combined use. We report two episodes of neurotoxicity and nephrotoxicity in a patient following the combined use of lithium and risperidone. CASE PRESENTATION: A 55-year-old male had a diagnosis of schizoaffective disorder at the age of 51...

BACKGROUND: Clozapine is the archetypical atypical antipsychotic, its primary indication being treatment resistant schizophrenia. Severe side effects caused by clozapine, including leukopenia, agranulocytosis, and myocarditis, are well known. A rarely described side effect is concurrent perimyocarditis and parenchymal lung disease. CASE PRESENTATION: A previously physically healthy 23-year-old male Caucasian that suffered from schizophrenia presented with flu-like symptoms 1 week after starting clozapine treatment...

We report the case of a 19-year-old female patient who had progressive chorea associated with a GNAO1 mutation. Chorea was refractory to multiple anticonvulsants, and the patient suffered from tiapride-induced neuroleptic malignant syndrome. After identification of a GNAO1 missense mutation at the age of 18years, topiramate treatment was initiated and the frequency of chorea decreased dramatically. The efficacy of topiramate may have been related to the inhibitory modulation of voltage-activated Ca(2+) channels...

A 27-year-old woman with panic disorder taking 20 mg olanzapine daily for 4 months was admitted to our hospital because of disturbed consciousness with fever, hyperglycemia, hyperosmolarity, and elevated creatine phosphokinase. She was diagnosed with a hyperosmolar hyperglycemic state (HHS) and neuroleptic malignant syndrome (NMS). Brain magnetic resonance imaging (MRI) showed transiently restricted diffusion in the splenium of the corpus callosum (SCC), with a high signal intensity on diffusion-weighted imaging...

Well-established practice guidelines and a solid body of evidence underpin the safe and effective use of electroconvulsive therapy (ECT), primarily in mood disorders. In this issue of the journal, 3 case reports deal with situations that fall outside of the usual guidelines: treatment resistance to ECT overcome by combined use with antidepressant medication; use of ECT in the presence of polymyositis; and use of ECT for an unusually severe case of neuroleptic malignant syndrome, assisted by consultation from an online expert resource...

Our team at Emory University Hospital contacted experts at the National Network of Depression Centers (NNDC) for clinical guidance concerning a patient with schizophrenia hospitalized in the intensive care unit with a complex case of prolonged delirium secondary to neuroleptic malignant syndrome (NMS). Through the NNDC, leading psychiatrists across the United States with expertise in electroconvulsive therapy (ECT) provided us with treatment strategies based on experience in our area of concern. This report describes our use of ECT to treat severe NMS in this patient with schizophrenia, utilizing the recommendations made by the NNDC's ECT experts concerning electrode position, number and frequency of treatments, and selection of anesthetic induction agents...

Neuroleptic malignant syndrome (NMS) is one of the most severe iatrogenic emergencies in clinical service. The symptoms including sudden consciousness change, critical temperature elevation and electrolytes imbalance followed by mutli-organ system failure were common in NMS. In addition to aggressive interventions with intravenous fluid resuscitation and antipyretics, several antidotes have been suggested to prevent further progression of the muscle damage. Dantrolene has been reported to be one of the most effective treatments for NMS...

We present the case of a 77-year-old man with a 10-year history of Parkinson disease (PD), who developed posterior reversible encephalopathy syndrome (PRES). We diagnosed the case as PRES based on clinical features and MRI findings. He experienced orthostatic hypotension and supine hypertension, including nocturnal hypertension. PRES may result from marked supine/nocturnal hypertension and fluctuation in blood pressure. In addition, exacerbated factors could be representative of neuroleptic malignant syndrome...
