OBJECTIVE: To present a case that demonstrates that seizures and interictal disturbances can be driven by a small area of functionally abnormal cortex. METHODS: Two novel functional MRI network analysis methods were used to supplement conventional seizure and lesion localization methods: (1) regional homogeneity to quantify local connectivity, or synchrony, with a resolution of less than 1 cm(3) of cortex; and (2) small-worldness to combine information about whole brain network segregation and integration...

This was a prospective observational study to correlate the clinical symptoms, electrophysiology, imaging, and surgical pathology of patients with temporal lobe epilepsy (TLE) without hippocampal sclerosis. We selected consecutive patients with TLE and normal MRI undergoing temporal lobe resection between April and September 2015. Clinical features, imaging, and functional data were reviewed. Intracranial monitoring and language mapping were performed when it was required according to our team recommendation...

PURPOSE: Some studies have suggested that BAFF and BAFFR are highly expressed in the central nervous system (CNS) and participate in inflammatory and immune associated diseases. However, whether BAFF and BAFFR are involved in the pathogenesis of epilepsy remains unknown. This study aimed to investigate the expression of BAFF and BAFFR proteins in the brains of patients with temporal lobe epilepsy (TLE) and in a pilocarpine-induced rat model of TLE to identify possible roles of the BAFF-BAFFR signaling pathway in epileptogenesis...

Febrile infection-related epilepsy syndrome (FIRES) is a form of epileptic encephalopathy with severe refractory epilepsy that presents in previously healthy, school-aged children after significant febrile illness with concomitant rise in body temperature. Suspected causes include genetic or acquired channelopathies, as well as mitochondrial disturbances. In FIRES, the EEG shows diffuse slowing, generalized, and/or multifocal discharges. Seizures are present and resistant to treatment. Moyamoya angiopathy (MMA) is characterized by progressive stenosis of cerebral arteries and subsequent development of a network of collateral circulation that is prone to rupture...

Temporal lobe epilepsy (TLE) is a common and severe neurological disorder which is often intractable. It can not only damage the normal structure and function of hippocampus, but also affect the neurogenesis in dentate gyrus (DG). It is well documented from researches on the animal models of TLE that after a latent period of several days, prolonged seizure activity leads to a dramatic increase in mitotic activity in the hippocampal DG. However, cell proliferation returns to baseline levels within 3-4 weeks after status epilepticus (SE)...

REVIEW
Katherine C Nickels, Elaine C Wirrell
Stiripentol is a structurally unique antiepileptic drug that has several possible mechanisms of action, including diverse effects on the gamma-aminobutyric acid (GABA)-A receptor and novel inhibition of lactate dehydrogenase. Because of its inhibition of several cytochrome P450 enzymes, it has extensive pharmacokinetic interactions, which often necessitates reduction in doses of certain co-therapies, particularly clobazam. Stiripentol also has a neuroprotective action, by reducing calcium-mediated neurotoxicity...

PURPOSE: Vagus nerve stimulation (VNS) has shown to be an effective treatment for drug resistant epilepsy, with achieving more than 50% seizure reduction in one third of the treated patients. In order to predict which patients will profit from VNS, we previously found that a low pairwise derived Brain Symmetry Index (pdBSI) could potentially predict good responders to VNS treatment. These findings however have to be validated before they can be generalized. METHODS: 39 patients (age 18-68 years) with medically intractable epilepsy who were referred for an implanted VNS system were included...

The activation of phosphatidylinositol 3-kinase-AKTs-mammalian target of rapamycin cell signaling pathway leads to cell overgrowth and abnormal migration and results in various types of cortical malformations, such as hemimegalencephaly (HME), focal cortical dysplasia, and tuberous sclerosis complex. However, the pathomechanism underlying abnormal cell migration remains unknown. With the use of fetal mouse brain, we performed causative gene analysis of the resected brain tissues from a patient with HME and investigated the pathogenesis...

Hemispherectomy (HS) is an effective surgical procedure aimed at managing otherwise intractable epilepsy in cases of diffuse unihemispheric pathologies. Neurological recovery in subjects treated with HS is not limited to seizure reduction, rather, sensory-motor and behavioral improvement is often observed. This outcome highlights the considerable capability of the brain to react to such an extensive lesion, by functionally reorganizing and rewiring the cerebral cortex, especially early in life. In this narrative review, we summarize the animal studies as well as the human neurophysiological and neuroimaging studies dealing with the reorganizational processes that occur after HS...

While Vagus Nerve Stimulation (VNS) is proven to be a safe and effective adjunctive therapy in the general population with medically intractable seizures, little is published about its implantation during pregnancy. Here we illustrate the case of a 21year old primigravid woman with medically refractory seizures who underwent safe and successful VNS implantation and immediate activation of the device in her 32nd week of pregnancy, resulting in dramatically improved seizure control and subsequent delivery of a healthy baby...

OBJECTIVE: Evaluate the seizure-reduction response and safety of mesial temporal lobe (MTL) brain-responsive stimulation in adults with medically intractable partial-onset seizures of mesial temporal lobe origin. METHODS: Subjects with mesial temporal lobe epilepsy (MTLE) were identified from prospective clinical trials of a brain-responsive neurostimulator (RNS System, NeuroPace). The seizure reduction over years 2-6 postimplantation was calculated by assessing the seizure frequency compared to a preimplantation baseline...

This study aims to identify the risk factors leading to the development of severe scoliosis among children with cerebral palsy. A cross-sectional descriptive study of 70 children (aged 12-18 years) with severe spastic and/or dystonic cerebral palsy treated in a single specialist unit is described. Statistical analysis included Fisher exact test and logistic regression analysis to identify risk factors. Severe scoliosis is more likely to occur in patients with intractable epilepsy ( P = .008), poor gross motor functional assessment scores ( P = ...

Dysfunction of synaptic neurotransmitter release is closely involved in the pathogenesis of various central nervous system diseases. Synaptic vesicle glycoprotein 2A (SV2A) is a membrane protein specifically expressed in synaptic vesicles and it modulates action potential-dependent neurotransmitter release in the brain. Since 1) SV2A-knockout mice exhibit severe convulsive seizures, 2) SV2A expression in the brain is reportedly altered in various epileptic disorders both in animal models (e.g., kindling and genetic models) and humans (e...

Temporal lobe resection is the most prevalent epilepsy surgery procedure. However, there is no consensus on the best surgical approach to treat temporal lobe epilepsy. Complication rates are low and efficacy is very high regarding seizures after such procedures. However, there is still ample controversy regarding the best surgical approach to warrant maximum seizure control with minimal functional deficits. We describe the most frequently used microsurgical techniques for removal of both the lateral and mesial temporal lobe structures in the treatment of medically intractable temporal lobe epilepsy (TLE) due to mesial temporal sclerosis (corticoamygdalohippocampectomy and selective amygdalohippocampectomy)...

A young man with normal neurodevelopment presented with 3 years of medically refractory, progressive epilepsy and myoclonus. Initial examination included neuroimaging, electroencephalography, and biochemical analyses, all of which were unremarkable except for mildly enlarged ventricles. Over the following year, the patient experienced rapid cognitive decline with new-onset recurrent visual hallucinations and progressive lethargy. Results of subsequent electroencephalography and brain imaging were unchanged, and a fluorodeoxyglucose F 18 positron emission tomographic scan was normal...

Importance: Children with benign epilepsy with centrotemporal spikes (BECTS) have traditionally been considered to have a uniformly good prognosis. However, benign may be a misnomer because BECTS is linked to cognitive deficits, a more severe phenotype with intractable seizures, and the potential for sudden unexpected death in epilepsy (SUDEP). Objective: To determine if cases of BECTS are present in the North American SUDEP Registry (NASR). Design, Setting, and Participants: The NASR is a clinical and biospecimen repository established in 2011 to promote SUDEP research...

PURPOSE: Patients with epilepsy are frequently required to take antiepileptic drugs (AEDs) for a long period of time. Many studies have shown that AEDs have a negative influence on endocrine function including the thyroid gland, however the risk factors for the development of low thyroid function in these patients are unclear. This study aimed to determine the potential risk factors of low thyroid function in patients with epilepsy. METHOD: This was a cross-sectional study including 298 patients with epilepsy...

Epileptic encephalopathies encompass a heterogeneous group of epilepsy syndromes that manifest with cognitive, behavioral, and neurologic deficits, seizures that are often intractable and multiform, aggressive electroencephalographic paroxysmal activity, and sometimes early death. As more is learned about the etiologies and manifestations of epileptic encephalopathies, progress has been made toward better treatment options. However, there is still a great need for further randomized controlled trials and research to help create clinically effective therapies...
