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...

A 42-year-old Japanese woman with a 10-year history of schizophrenia was admitted due to a disturbance in consciousness that met the diagnostic criteria for both neuroleptic malignant syndrome (NMS) and malignant catatonia. Despite systemic supportive treatments, the catatonic symptoms preceding autonomic symptoms persisted. The symptoms improved after lorazepam administration, leading to a retrospective diagnosis of malignant catatonia. Catatonia is thought to be caused by a dysfunction of ganmma-aminobutyric acid type A receptors in the cortico-cortical networks of the frontal lobes, which causes hypoactivity of the dopaminergic transmission in the subcortical areas...

Paliperidone, an active metabolite of risperidone, is a new atypical antipsychotic agent. Syndrome of inappropriate antidiuretic hormone (SIADH), neuroleptic malignant syndrome (NMS), and rhabdomyolysis are the uncommon side effects of psychotropic drugs. We report a case of 35-year-old male with schizoaffective disorder who was admitted for acute-on-chronic exacerbation of his psychotic disorder for which intramuscular paliperidone 234 mg injection was given. Two days later, the patient developed hyponatremic seizures secondary to SIADH which was treated with hypertonic saline...

Risperidone is a widely used, second-generation antipsychotic approved for treating schizophrenia as well as for treating aggression in children and adolescents with mental retardation. The substance has a well-established risk profile including alterations of body temperature. Apart from hyperthermia with and without full-blown malignant neuroleptic syndrome, low body temperatures (hypothermia) have also been reported anecdotally, usually appearing in the context of comedication. Here, we report a case of hypothermia associated with a low-dose risperidone monotherapy in a child...

Soma (Carisoprodol) is N-isopropyl-2 methyl-2-propyl-1,3-propanediol dicarbamate; a commonly prescribed, centrally acting skeletal muscle relaxant. Neuroleptic malignant syndrome (NMS) is a potentially life-threatening adverse effect of antipsychotic agents. Although diagnostic criteria for NMS have been established, it should be recognized that atypical presentations occur and more flexible diagnostic criteria than currently mandated, may be warranted. We wish to report a postoperative case of bilateral knee replacement who presented with carisoprodol (Soma) withdrawal resembling NMS that was a diagnostic dilemma...

This report aims at raising clinical awareness for the diagnosis of atypical presentations of neuroleptic malignant syndrome (NMS). We describe the case of a female patient with NMS symptoms, except fever, after starting the use of chlorpromazine. The afebrile condition delayed the consideration of NMS by the emergency clinicians who provided her initial assessment. Before this consideration, an anticholinergic agent, not recommended at this condition, was inadvertently prescribed. This might have contributed to the worsening of symptoms...

This case is important because it is the first time Olanzapine-induced fever has been described in the absence of neuroleptic malignant syndrome. In the context of the available antipsychotics with the atypical agents dominating the pool, only few of those are known to be well tolerated among the patients. Fever may be looked at by the physicians as a minor problem yet, it can be disabling to the large set of patients. Fever was not considerably listed as one of the side effects for Olanzapine and should not be confused with the incomplete neuromalignant syndrome...

BACKGROUND: Anti-N-methyl-D-aspartate receptor encephalitis is an autoimmune disorder characterized by behavioral changes, dyskinesia, and autonomic instability. PATIENT DESCRIPTION: We describe a 14-year-old girl who initially presented with acute behavioral changes and seizures and who over a 2-week period developed high fever, tachycardia, and elevated blood pressures. RESULTS: Because she received multiple medications including anticonvulsants and a neuroleptic, our patient was initially diagnosed with neuroleptic malignant syndrome, a disorder characterized by autonomic dysfunction, hyperthermia, muscle rigidity, and mental status changes usually caused by the use of a neuroleptic agent...

REVIEW
Daniel J Niven, Kevin B Laupland
Elevation in core body temperature is one of the most frequently detected abnormal signs in patients admitted to adult ICUs, and is associated with increased mortality in select populations of critically ill patients. The definition of an elevated body temperature varies considerably by population and thermometer, and is commonly defined by a temperature of 38.0 °C or greater. Terms such as hyperthermia, pyrexia, and fever are often used interchangeably. However, strictly speaking hyperthermia refers to the elevation in body temperature that occurs without an increase in the hypothalamic set point, such as in response to specific environmental (e...

Disulfiram is a widely used drug in the management of alcohol dependence syndrome as an aversive agent. Although a drug of high efficacy, it has a large number of side effects. Disulfiram-induced catatonia is a known rare side effect of the drug and herein we report a case of what appeared to be the sequential development of malignant catatonia and neuroleptic malignant syndrome in a patient with a diagnosis of alcohol dependence syndrome and co-morbid paranoid schizophrenia following disulfiram overdose. Clinicians need to be vigilant on the emergence of such rare side effects...

Behavioral and psychological symptoms of dementia pose management challenges for caregivers and clinicians. Firstline nonpharmacologic treatments include eliminating physical and emotional stressors, modifying the patient's environment, and establishing daily routines. Family members and caregivers benefit from education about dementia symptoms and reminders that the behaviors are normal and unintentional. Cognitive and emotion-oriented interventions, sensory stimulation interventions, behavior management techniques, and other psychosocial interventions are modestly effective...

Aripiprazole is a partial dopamine agonist with only minor neurological and psychiatric adverse effects, making it a potential first-line drug for the treatment of psychiatric disorders. However, the evidence of its use in children and adolescents is rather sparse. The aim of this case study is to discuss adverse drug reaction (ADR) reports concerning aripiprazole-associated neurological and psychiatric events in children and adolescents. The ADR report database at Danish Medicines Agency was searched for all ADRs involving children and adolescents (<18 years) reported by the search term [aripiprazole] AND all spontaneous reports since the introduction of aripiprazole in 2003 until December 31, 2015...

Linn E Katus, Steven J Frucht
Serotonin syndrome (SS) and neuroleptic malignant syndrome (NMS) can present similarly and range in severity from mild to life-threatening. Although they are easily misdiagnosed, each is distinct clinically and pathophysiologically. It is important to distinguish between the two, as therapeutic options differ. An accurate and thorough medication history plus knowledge of the various clinical presentations of both syndromes are the first steps in management. After this, removing the offending agents and aggressive supportive care are crucial...
