OBJECTIVE: The intravenous formulation of lacosamide (LCM) and its good overall tolerability and safety favor the use in status epilepticus (SE). The aim of this systematic review was to identify and evaluate studies reporting on the use of LCM in SE. METHODS: We performed a systematic literature search of electronic databases using a combined search strategy from 2008 until October 2016. Using a standardized assessment form, information on the study design, methodologic framework, data sources, efficacy, and adverse events attributed to LCM were extracted from each publication and systematically reported...

BACKGROUND AND OBJECTIVES: Nowadays, there is an ongoing discussion about the risks and benefits of anesthetic treatment concerning outcome in status epilepticus (SE). Therefore, we performed a retrospective database analysis to examine the influence of treatment with anesthetic drugs and narcosis in SE on mortality and disability. METHODS: All treatment episodes of SE at the Department of Neurology of the University of Rostock between 01 January 2000 and 31 December 2009 were evaluated...

BACKGROUND: Creutzfeldt-Jacob disease (CJD) is a human prion disease generally characterized by subacute changes in behavior and intellectual function, often followed by ataxia, vision changes, and myoclonus. Ten percent of cases may present atypically, both symptomatically and in respect to initial investigations. METHODS: We report a case of CJD mimicking acute stroke and review all similar cases in the magnetic resonance imaging era reported in English, identified through a PubMed and SCOPUS search...

Despite a wide number of studies trying to define clinical, physiopathological, and neuroradiological features of posterior reversible encephalopathy syndrome (PRES), the true nature of symptoms is still not fully understood. We studied a standard cohort of 24 pediatric patients, affected by hemato-oncological diseases, with a neuroradiological diagnosis consistent with PRES identified from 2006 to 2013. Ten of them developed PRES after hematopoietic stem cell transplantation. We analyzed the sequence of clinical, radiological, and electrophysiological data...

OBJECTIVE: To describe EEG and clinical correlates, DC recordings and prognostic significance of cyclic seizures (CS). METHODS: We reviewed our prospective continuous EEG database to identify patients with CS, controls with non-cyclic status epilepticus (SE) and controls without seizure matched for age and etiology. EEG was reviewed with DC settings. RESULTS: 39/260 (15%) patients with electrographic seizures presented with CS. These patients were older (62 vs...

Objective. We are reporting two cases: a patient with steroid responsive encephalopathy associated with autoimmune thyroiditis (SREAT) and another patient with secondary progressive multiple sclerosis (SPMS), both presenting with altered mental status (AMS) and later diagnosed with nonconvulsive atypical absence status epilepticus (AS), with atypical EEG changes. Methods. A report of two cases. Results. A patient with history of SREAT and the other with SPMS had multiple admissions due to AMS. For both, EEG revealed the presence of a high voltage generalized sharply contoured theta activity...

A 9-year-old girl presented with alleged history of deliberate ingestion of 4 g of carbamazepine, following which she became comatose. A bedside electroencephalogram (EEG) was performed to rule out nonconvulsive status epilepticus, which showed presence of spindle coma (SC), not reactive to noxious stimuli. Following hemodialysis, a second EEG showed absence of SC and complete clinical recovery. We present this unique case of carbamazepine-induced SC, thereby highlighting the extent of the etiologic spectrum of SC and discussing the literature related to this association...

Neurologic complications in polytrauma can be classified by etiology and clinical manifestations: neurovascular, delirium, and spinal or neuromuscular problems. Neurovascular complications include ischemic strokes, intracranial hemorrhage, or the development of traumatic arteriovenous fistulae. Delirium and encephalopathy have a reported incidence of 67-92% in mechanically ventilated polytrauma patients. Causes include sedation, analgesia/pain, medications, sleep deprivation, postoperative state, toxic ingestions, withdrawal syndromes, organ system dysfunction, electrolyte/metabolic abnormalities, and infections...

Critically ill patients with seizures are either admitted to the intensive care unit because of uncontrolled seizures requiring aggressive treatment or are admitted for other reasons and develop seizures secondarily. These patients may have multiorgan failure and severe metabolic and electrolyte disarrangements, and may require complex medication regimens and interventions. Seizures can be seen as a result of an acute systemic illness, a primary neurologic pathology, or a medication side-effect and can present in a wide array of symptoms from convulsive activity, subtle twitching, to lethargy...

Seizures are a common occurrence following cardiac arrest and may occur both during targeted temperature management and after rewarming. Postanoxic seizures may be nonconvulsive and very difficult to diagnose without electroencephalography (EEG) or associated with prominent myoclonus. Importantly, to date no randomized controlled trials are available to guide the management of seizures in patients with cardiac arrest. Seizure prophylaxis is not recommended, and when seizures are diagnosed they are typically treated the same as seizures in other patients with acute brain injury...

Cefepime-induced encephalopathy including nonconvulsive status epilepticus has been known to develop in the patients with renal impairment. However, we report a 74-year-old woman with normal renal function who developed stuporous mental status during cefepime administration. Electroencephalogram (EEG) revealed 2 Hz rhythmic sharp-and-waves continuously, which suggested nonconvulsive status epilepticus (NCSE). After cefepime discontinuation, clinical symptoms recovered gradually and EEG findings showed only background slowing without epileptiform discharges...

BACKGROUND: In the diagnosis of nonconvulsive status epilepticus (NCSE), capture of ongoing ictal electroencephalographic (EEG) findings is the gold standard; however, this is practically difficult without continuous EEG monitoring facilities. Magnetic resonance imaging (MRI), including diffusion-weighted imaging (DWI) and perfusion MRI with arterial spin labeling (ASL), have been applied mainly in emergency situations. Recent reports have described that ictal MRI findings, including ictal hyperperfusion on ASL and cortical hyperintensity of cytotoxic edema on DWI, can be obtained from epileptically activated cortex...

Status epilepticus (SE) is a common neurologic emergency and a frequent reason for admission to the intensive care unit. During the last decade, the advent and availability of diagnostic tools for the recognition of nonconvulsive SE has highlighted an even higher incidence of this condition among the critically ill. New alternatives in treatment have also become available within recent years. The recommendation of early escalation toward the use of general anesthetics in the treatment of convulsive SE follows the theory that the duration of the event defines the aggressiveness of the condition and the potential for long-term neuronal injury...

BACKGROUND: Status epilepticus (SE) often does not respond to initial treatment. A second-line agent with a less established safety and efficacy profile is then required. This study examined the safety of intravenous (IV) lacosamide (LCM) in a critically ill population and obtained an estimate of effectiveness in patients with refractory SE on continuous video EEG monitoring (cEEG). METHODS: Retrospective review of critically ill patients in SE on cEEG treated with IV LCM from June 2009 to April 2011...

INTRODUCTION: Status epilepticus (SE) is a life-threatening neurologic emergency. Despite advances in management, in-hospital mortality remains unchanged. This is partly due to the pharmacoresistance which develops the longer that seizures persist. Therefore, rapid antiseizure medication (ASM) administration may represent a beneficial treatment option. The purpose of this study was to determine: 1) whether in-hospital mortality is reduced with shorter latencies to initial treatment of SE with an ASM (LTSE); and 2) the critical time frame during which LTSE is associated with reduced in-hospital mortality...

Santoshi Billakota, Saurabh R Sinha
INTRODUCTION: Continuous EEG (cEEG) monitoring is used in the intensive care unit (ICU) setting to detect seizures, especially nonconvulsive seizures and status epilepticus. The utility and impact of such monitoring in non-ICU patients are largely unknown. METHODS: Hospitalized patients who were not in an ICU and underwent cEEG monitoring in the first half of 2011 and 2014 were identified. Reason for admission, admitting service (neurologic and nonneurologic), indication for cEEG, comorbid conditions, duration of recording, EEG findings, whether an event/seizure was recorded, and impact of EEG findings on management were reviewed...

PURPOSE: Subdural hematomas (SDH) are associated with seizures and epileptiform discharges, but little is known about the prevalence and impact of seizures, status epilepticus (SE), and epileptiform discharges on outcomes in patients with isolated acute SDH (aSDH). METHODS: Continuous EEG reports from 76 adult patients admitted to Rush University Medical Center with aSDH between January 2009 and March 2012 were reviewed. Clinical and radiographic findings, comorbidities, treatment, and outcome parameters, such as mortality, discharge destination, need for tracheostomy/percutaneous endoscopic gastrostomy placement, and length of stay (LOS), were assessed...

Animal models of status epilepticus are important tools to understand the pathogenesis of epileptic brain injury and evaluate potential seizure-suppressive, neuroprotective, and antiepileptogenic treatments. Focal elicitation of status epilepticus by intraamygdala kainic acid in mice produces unilateral hippocampal damage and the emergence of spontaneous recurrent seizures after a short latent period. The model has been characterized in C57BL/6, BALB/c, and SJL mice where strain-specific differences were found in the extent of hippocampal damage...

Status epilepticus (SE) is rarely described in patients with juvenile myoclonic epilepsy (JME), and little is known about its frequency, subtypes, and predictors and the prognosis of these patients. In this retrospective study, we aimed to analyze the incidence of SE in patients with JME and emphasize the risk factors and long-term outcome of SE in an epilepsy outpatient-based cohort. We included patients with JME with a history of predominant myoclonic seizures and at least one diagnostic EEG with normal background activity and bursts of typical ≥3-Hz generalized spike-polyspike and waves...
