There have been recent reports of antibody-mediated status epilepticus. The objective of our study was to investigate the prevalence of neuronal autoantibodies in patients with status epilepticus (SE) with unresolved etiology. The presence of neuronal autoantibodies was investigated prospectively in adult patients with SE who presented to our clinic between February 2012 and December 2013 with unresolved etiology. Clinical and electrophysiologic features of seropositive patients were recorded. Also, seronegative and seropositive patient groups were compared in terms of demographic and clinical features, treatment responses, and outcomes...

BACKGROUND: Intranasal administration of benzodiazepines has shown superiority over rectal administration for terminating emergency epileptic seizures in human trials. No such clinical trials have been performed in dogs. OBJECTIVE: To evaluate the clinical efficacy of intranasal midazolam (IN-MDZ), via a mucosal atomization device, as a first-line management option for canine status epilepticus and compare it to rectal administration of diazepam (R-DZP) for controlling status epilepticus before intravenous access is available...

OBJECTIVE: Our primary objective is to verify whether 5-HTR6 is involved in the development of mossy fiber sprouting (MFS), and to determine how the progression of MFS is affected by 5-HTR6. METHODS: A total of 90 male adult Sprague-Dawley rats were allocated into either the control group (n=36) or the epileptic group (n=54). Status epilepticus (SE) of rats was induced by the intraperitoneal (i.p.) injection of LiCl-pilocarpine. We conducted our experiments in two stages...

REVIEW
David G Olmes, Hajo M Hamer
According to current diagnosis criteria, first seizures constitute beginning epilepsy when they carry recurrence risks of ≥60% over the next 10 years. This is frequently the case and warrants AED treatment. Evidence argues against deferring treatment when provoking factors such as sleep deprivation are reported. There are several characteristics of first seizures which markedly increase recurrence risk but not clearly beyond 60%. This includes status epilepticus or seizure flurries at first manifestation or focal semiology indicating focal epilepsy...

Vasogenic edema induced by blood brain barrier disruption and neuronal loss play an important role in the epileptogenic process. 4,4'- diisothiocyanatostilbene-2,2'-disulfonic acid (DIDS) is a commonly used anion channel inhibitor that has been reported to exert an anticonvulsant effect in rat hippocampus in vitro. The present study aimed to investigate whether DIDS could prevent epileptogenic process in rat lithium-pilocarpine model of temporal lobe epilepsy. The tight junction proteins and serum extravasation were examined in the piriform cortex 3days after status epilepticus...

AIM: Mowat-Wilson Syndrome (MWS) is a genetic rare disease. Epilepsy is present in 70-75% of Patients and an age-dependent electroclinical pattern has been described. Up to date, there are studies with overnight sleep EEGs, probably because of the severe intellectual disability (ID) and hyperactivity of these Patients. Our purpose was to verify the hypothesis that MWS Patients might have electrical status epilepticus in slow wave sleep (ESES pattern). METHODS: A retrospective analysis of anamnestic and electrographic data was performed on 7 consecutive MWS Patients followed between 2007 and 2016...

BACKGROUND: Seizures and status epilepticus (SE), both clinical and subclinical, are frequent in critically ill patients. The list of available anti-seizure medications (ASMs) is expanding and now includes older and widely used drugs as well as more recent medications with a better safety and pharmacokinetics profile. METHODS: We review a selection of recent publications about the indications and administration of ASMs in critical care for the prophylaxis and treatment of seizures and SE, focusing on recent ASMs available as intravenous formulation and emphasizing pharmacokinetics and safety issues in relation to several aspects of critical illness...

Status Epilepticus (SE) is the most common neurological emergency of childhood. It requires prompt administration of appropriately selected anti-seizure medications. Areas covered: Following a distinction between estabilished and emergent drugs, we present pharmacological treatment options and their clinical utility in children, with a short mention on alternatives to drug treatment. We also propose an algorithm for the management of pediatric SE. For this review a Pubmed, Medline and Embase search was performed...

OBJECTIVE: Neuroinflammatory processes are pathologic hallmarks of both experimental and human epilepsy, and could be implicated in the neuronal hyperexcitability. Aspirin represents one of the non-selective nonsteroidal anti-inflammatory drugs with fewer side effects in long-term application. This study was carried out to assess the anti-epileptic effects of aspirin when administered during the chronic stage of temporal lobe epilepsy [TLE] in mice. The alteration of hippocampal neurogenesis was also examined for raising a possible mechanism underlying the protective effect of anti-inflammatory treatment in the TLE...

OBJECTIVE: Temporal lobe epilepsy (TLE) is commonly associated with depression, anxiety, and cognitive impairment. Despite significant progress in our understanding of the pathophysiology of TLE, it remains the most common form of refractory epilepsy. Enriched environment (EE) has a beneficial effect in many neuropsychiatric disorders. However, the effect of EE on cognitive changes in chronic TLE has not been evaluated. Accordingly, the present study evaluated the effects of EE on chronic epilepsy-induced alterations in cognitive functions, electrophysiology, and cellular changes in the hippocampus...

BACKGROUND: Epilepsy is a disorder of the central nervous system characterized by recurrent seizures. It is a very common disease in which approximately 30% of patients do not respond favourably to treatment with anticonvulsants. Oxidative stress is associated with neuronal damage arising from epileptic seizures. The present study investigated the effects of naringenin in pilocarpine-induced epilepsy in mice. Naringenin, one of the most frequently occurring flavanone in citrus fruits, was evaluated for its shielding effect against the pilocarpine induced behavioural, oxidative and histopathological alterations in rodent model of epilepsy...

BACKGROUND: Todd's paralysis (TP) is a well-known postictal paresis in which patients present with transient weakness in their limb(s) after seizures. Although recognized as a stroke mimic in clinical practice, the pathophysiological mechanism and clinical features of TP remain unknown. Furthermore, its diagnosis can be erroneous in neurological emergency practice. We aimed to illustrate the clinical features and identify factors associated with TP. METHODS: This single-center, retrospective observational study included consecutive adult patients who presented with convulsive seizure and were referred to an urban tertiary care emergency department between August 2010 and April 2016...

PURPOSE: In the current study, we explored the prevalence of physician-confirmed seizure clusters. We also investigated potential clinical factors associated with the occurrence of seizure clusters overall and by epilepsy type. METHODS: We reviewed medical records of 4116 adult (≥16years old) outpatients with epilepsy at our centers for documentation of seizure clusters. Variables including patient demographics, epilepsy details, medical and psychiatric history, AED history, and epilepsy risk factors were then tested against history of seizure clusters...

The septohippocampal cholinergic neurotransmission has long been implicated in seizures, but little is known about the structural features of this projection system in epileptic brain. We evaluated the effects of experimental epilepsy on the areal density of cholinergic terminals (fiber varicosities) in the dentate gyrus. For this purpose, we used two distinct post-status epilepticus rat models, in which epilepsy was induced with injections of either kainic acid or pilocarpine. To visualize the cholinergic fibers, we used brain sections immunostained for the vesicular acetylcholine transporter...

OBJECTIVE: To understand how monosynaptic inputs onto adult-born dentate granule cells (DGCs) are altered in experimental mesial temporal lobe epilepsy (mTLE) and whether their integration differs from early-born DGCs that are mature at the time of epileptogenesis. METHODS: A dual-virus tracing strategy combining retroviral birthdating with rabies virus-mediated putative retrograde trans-synaptic tracing was used to identify and compare presynaptic inputs onto adult- and early-born DGCs in the rat pilocarpine model of mTLE...

Status epilepticus is a common manifestation of nerve agent toxicity and represents a serious medical emergency with high rates of mortality and neurologic injury in those that survive. The aim of the current study was to determine if targeting oxidative stress with the catalytic antioxidant, AEOL10150, would reduce pilocarpine-induced mortality and attenuate neuronal death and neuroinflammation. We found that treatment with AEOL10150 in conjunction with scopolamine and diazepam following pilocarpine-induced SE was able to significantly reduce mortality compared to treatment with just scopolamine and diazepam...

Early maladaptive internalization of synaptic GABAA receptors (GABAAR) and externalization of NMDA receptors (NMDAR) may explain the time-dependent loss of potency of standard anti-epileptic drugs (AED) in refractory status epilepticus (SE). We hypothesized that correcting the effects of changes in GABAAR and NMDAR would terminate SE, even when treatment is delayed 40 minutes. SE was induced in adult Sprague-Dawley rats with a high dose of lithium and pilocarpine. The GABAAR agonist midazolam, the NMDAR antagonist ketamine and the AED valproate were injected 40 min after SE onset in combination or as monotherapy...

We explored the influence of four different efficacy criteria on the results of observational studies concerning the treatment of status epilepticus (SE) and its subtypes. We compared and contrasted the results of four different efficacy criteria for the effectiveness of phenytoin, valproate, levetiracetam, and lacosamide. Criterion 1=the last antiepileptic drug (AED) administered before SE termination. Criterion 2=the last drug introduced into the antiepileptic therapy within 72h before the cessation of SE and without changes in dosage or number of the co-medication...

We report a patient who experienced atypical symptoms in the course of electroconvulsive therapy (ECT). During ECT treatment patient experienced psychotic symptoms which should be differentiated with prolonged delirium and nonconvulsive status epilepticus. 46-year-old female was referred to hospital with a diagnosis of major depressive disorder with no psychotic features in the course of recurrent depression. Despite several changes of pharmacological treatment no improvement was achieved, therefore it was decided to initiate ECT...
