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...

PURPOSE: To determine if there are differences in the timing of diagnosis and response to treatment between infants with infantile spasms (IS) and Trisomy 21 (T21) and those with idiopathic IS. METHOD: This was a retrospective study evaluating the time from onset of IS to diagnosis, treatment of IS, time from treatment to resolution of IS, and development of epilepsy in children with T21 and IS compared to children with idiopathic IS. RESULTS: Thirteen children with T21 and IS were identified over a 10 year period and compared to 32 children in the control group...

INTRODUCTION: Idiopathic generalised epilepsies (IGE) are a set of electroclinical syndromes with different phenotypes. Our aim is to analyse those phenotypes in patients over 16 years of age. PATIENTS AND METHODS: We conducted a retrospective analysis of a series of patients with IGE. They were classified as childhood absence epilepsy (CAE), juvenile absence epilepsy (JAE), juvenile myoclonic epilepsy (JME), epilepsy with tonic-clonic seizures only (TCSE), epilepsy with eyelid myoclonias and absences (EMA) and pure photogenic epilepsy (PE)...

BACKGROUND: Fertility treatment includes hormonal stimulation of the woman and in vitro manipulation of gametes and embryos that may influence prenatal brain development. We aimed to investigate the association between fertility treatment and childhood epilepsy, including specific types of treatment and indications as well as subtypes of epilepsy. METHODS: In this nationwide birth cohort study, we included all pregnancies in Denmark resulting in live-born singletons, 1995-2003...

Myoclonic seizures are brief, involuntary muscular jerks arising from the central nervous system that can occur in different epilepsy syndromes, including idiopathic generalized epilepsies or the most severe group of epileptic encephalopathies. Valproate is commonly the first choice alone or in combination with some benzodiazepines or levetiracetam. However, more treatment options exist today as there is emerging evidence to support the efficacy of some newer antiepileptic drugs. In addition, of major importance remains avoidance of medications (e...

Estimated prevalence of canine idiopathic epilepsy is 0.6 per cent in the first-opinion canine population in the UK. Phenobarbital monotherapy has been reported to reduce/eradicate seizure activity in 60-93 per cent of idiopathic epileptic dogs (IEDs). The objective of this study was to evaluate safety and efficacy of the administration of phenobarbital orally every eight hours in IEDs with phenobarbital elimination half-life less than 20 hours. Medical records of 10 IEDs in which steady state trough serum phenobarbital levels were within the reference range and phenobarbital elimination half-life had become less than 20 hours following prolonged administration every 12 hours were reviewed...

OBJECTIVE: We aimed to identify the consistent regions of gray matter volume (GMV) abnormalities in idiopathic generalized epilepsy (IGE), and to study the difference of GMV abnormalities among IGE subsyndromes by applying activation likelihood estimation (ALE) meta-analysis. METHODS: A systematic review of VBM studies on GMV of patients with absence epilepsy (AE), juvenile myoclonic epilepsy (JME), IGE and controls indexed in PubMed and ScienceDirect from January 1999 to June 2016 was conducted...

OBJECTIVE: Visual hyperexcitability in the form of abnormal contrast gain control has been shown in photosensitive epilepsy and idiopathic generalized epilepsies. We assessed the accuracy and reliability of measures of visual contrast gain control in discerning individuals with idiopathic generalized epilepsies from healthy controls. METHODS: Twenty-four adult patients with idiopathic generalized epilepsy and 32 neurotypical control subjects from two study sites participated in a prospective, cross-sectional study...

BACKGROUND: The onset of generalized seizures is a long debated subject in epilepsy. The relative roles of cortex and thalamus in initiating and maintaining the different seizure types are unclear. OBJECTIVE: The purpose of the study is to estimate whether the cortex or the centromedian thalamic nucleus is leading in initiating and maintaining seizures in humans. METHODS: We report human ictal recordings with simultaneous thalamic and cortical electrodes from three patients without anesthesia being assessed for deep brain stimulation (DBS)...

Epilepsy is a serious neurologic disorder worldwide which affects about 1% of the population (ca. 50 million people), the highest prevalence occurring in both children and elderly. Apart from idiopathic forms, etiology of the disease involves multiple brain risk factors - the most frequent being cerebrovascular diseases, tumours and traumatic injuries. Several treatment options exist, including, for instance, pharmacotherapy, vagal nerve stimulation or epilepsy surgery. In spite of treatment, about 30% of patients with epilepsy still have seizures and become drug-refractory...

MBD5 (Methyl-CpG-binding domain 5) is a critical gene for normal development. While deletion or duplication of MBD5 may contribute to a genetic predisposition to autism spectrum disorders (ASD), intellectual disability, or epilepsy, the impact of rare MBD5 single nucleotide variants (SNVs) on neurodevelopmental features, particularly features with late onset, has not been fully explored. In this study, we conducted exon-targeted resequencing of MBD5 with next-generation sequencing technology in 562 Japanese patients (192 with idiopathic ASD and 370 with schizophrenia (SCZ)) and detected 16 MBD5 SNVs with allele frequencies of ≤1%...

Epileptic encephalopathies (EE) are the group of progressive conditions with various etiologies that can produce neurocognitive deficit both per se and due to constant epileptiform discharges. Epileptic encephalopathies constitute about 15% of epilepsy in childhood and 40% of all seizures occurring in the first 3 years of life. Ten syndrome forms of EE are identified. Genetic factors contribute to 70-80% of all epileptic diseases and approximately 40% of idiopathic epilepsies have a monogenic mode of inheritance...

Autism spectrum disorder (ASD) is a developmental brain disorder characterized by restricted and repetitive patterns of behavior, social and communication defects, and is commonly associated with difficulties with motor coordination. The etiology of ASD, while mostly idiopathic, has been linked to hereditary factors and teratogens, such as valproic acid (VPA). VPA is used clinically to treat epilepsy, mood disorders, and in the prevention of migraines. The use of VPA during pregnancy significantly increases the risk of ASD in the offspring...

There is increasing awareness and interest in the complex and extensive inter-relationships between sleep disorders and neurological disorders. This review focuses on the clinical interactions between obstructive sleep apnoea and stroke, headaches, epilepsy, cognition and idiopathic Parkinson's disease. We highlight to the neurologist the importance of taking a sleep history and considering the diagnosis and treatment of obstructive sleep apnoea.

BACKGROUND: Owing to the continuing improvements in imaging technology, an increasing number of epileptogenic small (≤5 mm) unruptured intracranial aneurysms (sUIAs) are being diagnosed. However, these sUIAs have not been systematically described and reviewed until now. CASE DESCRIPTION AND LITERATURE REVIEW: We report 2 patients with sUIAs who initially presented with complex partial seizures. Scalp electroencephalography identified the seizure activity as arising from the mesial temporal/frontal areas, but conventional magnetic resonance imaging (MRI) was normal in both patients...

PURPOSE: Long-term ketogenic diet (KD) treatment has been shown to induce liver steatosis and gallstone formation in some in vivo and clinical studies. The aim of this retrospective study was to evaluate the hepatic side effects of KD in epileptic children.
