BACKGROUND: Recent studies have shown a possible coexistence of absence seizures with other forms of epilepsy. The purpose of this study was to ascertain the possible contemporary or subsequent presence of childhood absence epilepsy (CAE) and benign epilepsy with centro-temporal spikes (BECTS) in pediatric epileptic patients. METHODS: A PubMed systematic search indexed for MEDLINE, PubMed and EMBASE was undertaken to identify studies in children including articles written between 1996 and 2015...

BACKGROUND AND PURPOSE: There are reports of successful resective epilepsy surgery for pediatric patients with epilepsy and generalized epileptiform discharges when they had focal epileptogenic lesions identified by MRI. However, there is limited information regarding adult patients with epilepsy who have both generalized epileptiform discharges and focal epileptogenic lesions. METHODS: To investigate the incidence and characteristics of adult patients who have both generalized epileptiform discharges and potentially epileptogenic lesions, we retrospectively analyzed data of clinical features and results of EEG and MRI of all patients with adult-onset epilepsy in a tertiary referral hospital...

Scott Fitzgerald, a world-renowned American writer, suffered from various health problems, particularly alcohol dependence, and died suddenly at the age of 44. According to descriptions in A Moveable Feast, by Ernest Hemingway, Fitzgerald had episodes resembling complex partial seizures, raising the possibility of temporal lobe epilepsy.

Importance: Periodic discharges (PDs) that do not meet seizure criteria, also termed the ictal interictal continuum, are pervasive on electroencephalographic (EEG) recordings after acute brain injury. However, their association with brain homeostasis and the need for clinical intervention remain unknown. Objective: To determine whether distinct PD patterns can be identified that, similar to electrographic seizures, cause brain tissue hypoxia, a measure of ongoing brain injury...

GOAL: Accurate determination of the epileptogenic focus is of paramount diagnostic and therapeutic importance in epilepsy. The current gold standard for focus localization is from ictal (seizure) onset and thus requires the occurrence and recording of multiple typical seizures of a patient. Localization of the focus from seizure-free (interictal) periods remains a challenging problem, especially in the absence of interictal epileptiform activity. METHODS: By exploring the concept of effective inflow, we developed a focus localization algorithm (FLA) based on directed connectivity between brain sites...

BACKGROUND: We wanted to identify in children with epilepsy the factors associated with seizure control and recurrence after a 2-year remission. METHODS: We did a 5-year follow-up of epileptic children whose antiepileptic medication had been stopped. Bivariate and multivariate analyses were used to compare features of electroencephalograms (EEGs) and clinical findings. In this study, 43 patients with and 64 without a seizure recurrence (SR) were enrolled. RESULTS: Clinical features strongly associated with SR in the univariate analysis included a symptomatic etiology for seizures, a history of status epilepticus, treatment duration before stopping antiepileptic drugs, and abnormal EEG findings at the time of stopping antiepileptic drugs...

OBJECTIVE: Rewiring of excitatory glutamatergic neuronal circuits is a major abnormality in epilepsy. Besides the rewiring of excitatory circuit, an abnormal depolarizing GABAergic drive has been hypothesized to participate in the epileptogenic processes. However, a remaining clinically relevant question is whether early post Status Epilepticus (SE) evoked chloride dysregulation is important for the remodeling of aberrant glutamatergic neuronal circuit. METHODS: Osmotic mini-pumps were used to infuse intracerebrally a specific inhibitor of depolarizing GABAergic transmission as well as a functionally blocking antibody towards the pan-neurotrophin receptor p75 (p75(NTR) )...

Genetic epilepsy with febrile seizures plus (GEFS(+)) is characterized by childhood-onset epilepsy syndrome. It involves febrile seizures and a variety of afebrile epileptic seizure types within the same pedigree with autosomal-dominant inheritance. Approximately 10% of individuals with GEFS(+) harbor SCN1A, a gene mutation in one of the voltage-gated sodium channel subunits. Considerably less common are focal epilepsies including complex partial seizures. We report vagus nerve stimulation (VNS) in a 6-year-old girl with GEFS(+) who exhibited refractory generalized tonic-clonic seizures and complex partial seizures...

PURPOSE: After radiation therapy (RT) to the brain, patients often experience memory impairment, which may be partially mediated by damage to the hippocampus. Hippocampal sparing in RT planning is the subject of recent and ongoing clinical trials. Calculating appropriate hippocampal dose constraints would be improved by efficient in vivo measurements of hippocampal damage. In this study we sought to determine whether brain RT was associated with dose-dependent hippocampal atrophy. METHODS AND MATERIALS: Hippocampal volume was measured with magnetic resonance imaging (MRI) in 52 patients who underwent fractionated, partial brain RT for primary brain tumors...

Seizures are among the most common presentations of brain tumors. Several tumor types can cause seizures in varying rates; neuroglial tumors and the gliomas are the most common ones. Brain tumors are the second most common cause of focal intractable epilepsy in epilepsy surgery series, with the highest frequency being dysembryoplastic neuroepithelial tumors and gangliogliomas. Seizure management is an important part of the treatment of patients with brain tumors. This review discusses clinical features and management of seizures in patients with brain tumors, including, neuroglial tumors, gliomas, meningioma and metastases; with the help of recent literature data...

The 'Photosensitivity Model' uses a standardized stimulation protocol of repeated intermittent photic stimulation (IPS) over a three-day period, with administration of a single dose of an investigational antiepileptic drug (AED) after a baseline IPS day in photosensitive patients, followed by a third IPS day to determine duration of effect. This 'Photosensitivity Model' has shown its' value in the development of new AEDs. Levetiracetam (LEV), currently a first-line AED in new-onset focal epilepsies, was not effective in classical animal models, but showed dose-dependent efficacy in the human 'Photosensitivity Model'...

BACKGROUND: Pregabalin binds to the α2δ auxiliary subunit of voltage-gated calcium channels, which are widely distributed throughout the central and peripheral nervous systems and modulate calcium-dependent neurotransmitter release. Pregabalin is indicated for the treatment of peripheral and central neuropathic pain, partial seizures with or without secondary generalization, and treatment of generalized anxiety disorder (GAD). OBJECTIVE: The purpose of this study was to assess the bioequivalence of two different formulations of pregabalin 150-mg capsules in healthy Korean male subjects under fasting conditions...

Anti-N-methyl D-aspartate receptor (anti-NMDAR) encephalitis, recently recognized as a form of paraneoplastic encephalitis, is characterized by a prodromal phase of unspecific illness with fever that resembles a viral disease. The prodromal phase is followed by seizures, disturbed consciousness, psychiatric features, prominent abnormal movements, and autonomic imbalance. Here, we report a case of anti-NMDAR encephalitis with initial symptoms of epilepsia partialis continua in the absence of tumor. Briefly, a 3-year-old girl was admitted to the hospital due to right-sided, complex partial seizures without preceding febrile illness...

Hyun Hee Lee, Yun Jung Hur
Glucose transport 1 (GLUT-1) deficiency is a rare syndrome caused by mutations in the glucose transporter 1 gene (SLC2A1) and is characterized by early-onset intractable epilepsy, delayed development, and movement disorder. De novo mutations and several hot spots in N34, G91, R126, R153, and R333 of exons 2, 3, 4, and 8 of SLC2A1 are associated with this condition. Seizures, one of the main clinical features of GLUT-1 deficiency, usually develop during infancy. Most patients experience brief and subtle myoclonic jerk and focal seizures that evolve into a mixture of different types of seizures, such as generalized tonic-clonic, absence, myoclonic, and complex partial seizures...

The 6-Hz corneal stimulation test is used to screen novel antiepileptic molecules to overcome the problem of drug refractoriness. Although recognized as a standard test, it has been evaluated only recently in the attempt to characterize the putative neuronal networks involved in seizures caused by corneal stimulation. In particular, by recording from the CA1 region we previously established that the hippocampus participates to propagation of seizure activity. However, these findings were not corroborated by using markers of neuronal activation such as FosB/ΔFosB antigens...

OBJECTIVES: Patients with epilepsy commonly report excessive daytime sleepiness and daytime fatigue, which may be attributed to the direct effect of seizures, a side effect of antiepileptic drugs or a combination of the two. The aim of the study was to compare sleep profiles in patients with juvenile myoclonic epilepsy (JME) and symptomatic partial epilepsy (PE) in drug naïve and treated patients using standardized sleep questionnaires. METHODS: Three study groups: - 1) juvenile myoclonic epilepsy (N=40) [drug naïve (N=20); On sodium valproate (SVA) (N=20)]; 2) symptomatic partial epilepsy (N=40) [drug naïve (N=20); On carbamazepine (CBZ) (N=20)]; 3) healthy controls (N=40) completed 3 standardized sleep questionnaires - Epworth Sleepiness Scale, Pittsburgh Sleep Quality Index, and NIMHANS Comprehensive Sleep Disorders Questionnaire...
