Genetically inherited absence epilepsy in humans is typically characterized by brief (seconds) spontaneous seizures, which involve spike-wave discharges (SWDs) in the EEG and interruption of consciousness and ongoing behavior. Genetic (inbred) models of this disorder in rats have been used to examine mechanisms, comorbidities and anti-absence drugs. SWDs have also been proposed as models of complex partial seizures (CPSs) following traumatic brain injury (post-traumatic epilepsy; PTE). However, the ictal characteristics of these rat models, including SWDs and associated immobility, are also prevalent in healthy outbred laboratory rats...

Epilepsy is a common neurological condition characterised by spontaneous recurrent seizures. Current anti-epileptic drugs are only effective and tolerated in ~70% of patients, leaving a substantial proportion of patients untreated. As such, there is a pressing need to develop new therapies. We assessed the anti-seizure activity of Neural Regeneration Peptide 2945 (NRP 2945) in the GAERS model of absence epilepsy. Drug effects on seizures were assessed using two study designs. Male adult GAERS were implanted with EEG electrodes to measure seizure frequency...

Neurotrophins, including nerve growth factor (NGF) and brain-derived neurotrophic factor (BDNF), bind to their high-affinity receptors to promote neuronal survival during brain development. One of the key downstream pathways is the phospholipase C (PLC) pathway, which not only plays a central role in calcium release from internal store but also in activation of TRPC channels coupled with neurotrophin receptors. TRPC channels are required for the neurotrophin-mediated neuronal protective effects. In addition, activation of TRPC channels is able to protect neurons in the absence of neurotrophin...

It has been shown for the first time that rearing by a foster Wistar mother with high level of maternal care (MC) counteracts the expression of genetic absence epilepsy (AE) and comorbid depression - reduces the number, duration and index of spike-wave discharges (SWDs) and immobility time in the forced swimming test, as well as exerts substantial effects on morphology and time-frequency dynamics of SWDs in WAG/Rij rats. It is supposed that increases in MC early in development might be used to counteract epileptogenesis and comorbid depression in people genetically predisposed to AE...

OBJECTIVE: To examine the association between autism spectrum disorder (ASD) and epilepsy in children. METHODS: A total of 190 children with ASD were enrolled. A self-designed questionnaire, Childhood Autism Rating Scale, and Autism Behavior Checklist were used to determine the association between ASD and epilepsy. RESULTS: Among the 190 children with ASD, 20 (10.5%) had epileptic seizures and 12 (6.3%) were diagnosed with epilepsy. The rates of abnormal physical development and hearing disorders before the age of one year were significantly higher in ASD children with epileptic seizures than in those without epileptic seizures (P<0...

MECP2 duplication syndrome (MDS) is a rare pediatric disease and mainly manifests as delayed motor development, language loss or delay, recurrent infection, severe intellectual disability, epilepsy, autistic symptoms, and early infantile hypotonia. In this article, the three children with this disease were all boys. Cases 1 and 2 had delayed motor development, and language loss or delay as initial manifestations, and case 3 had recurrent infection as initial manifestation. Physical examination showed hypotonia and negative pathological signs in each case...

As a subtype of idiopathic generalized epilepsies, absence epilepsy is believed to be caused by pathological interactions within the corticothalamic (CT) system. Using a biophysical mean-field model of the CT system, we demonstrate here that the feed-forward inhibition (FFI) in thalamus, i.e., the pathway from the cerebral cortex (Ctx) to the thalamic reticular nucleus (TRN) and then to the specific relay nuclei (SRN) of thalamus that are also directly driven by the Ctx, may participate in controlling absence seizures...

Synaptic downscaling is a homeostatic mechanism that allows neurons to reduce firing rates during chronically elevated network activity. Although synaptic downscaling is important in neural circuit development and epilepsy, the underlying mechanisms are poorly described. We performed small RNA profiling in picrotoxin (PTX)-treated hippocampal neurons, a model of synaptic downscaling. Thereby, we identified eight microRNAs (miRNAs) that were increased in response to PTX, including miR-129-5p, whose inhibition blocked synaptic downscaling in vitro and reduced epileptic seizure severity in vivo Using transcriptome, proteome, and bioinformatic analysis, we identified the calcium pump Atp2b4 and doublecortin (Dcx) as miR-129-5p targets...

BACKGROUND: People with epilepsy who became seizure-free while taking antiepileptic drugs might consider discontinuing their medication, with the possibility of increased quality of life because of the elimination of adverse events. The risk with this action, however, is seizure recurrence. The objectives of our study were to identify predictors of seizure recurrence and long-term seizure outcomes and to produce nomograms for estimation of individualised outcomes. METHODS: We did a systematic review and meta-analysis, and identified eligible articles and candidate predictors, using PubMed and Embase databases with a last update on Nov 6, 2014...

Primary generalized tonic clonic seizures (pGTCS) are still linked to major concerns for the clinic and hazards for patients suffering from idiopathic generalized epilepsy (IGE), so a quick search of the most effective and appropriate therapy is needed to control them. The key criteria for proper treatment are syndromic diagnosis and distinction between newly diagnosed and refractory patients. Other criteria include age, gender and comorbidities. Areas covered: Treatment for pGTCS has expanded in the last two years, with new antiepileptic drugs like perampanel joining valproic acid, lamotrigine, levetiracetam, topiramate, while further evidence-based data are required for zonisamide and lacosamide...

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...

Deep brain stimulation (DBS) can play a crucial role in the modulation of absence seizures, yet relevant biophysical mechanisms are not completely established. In this paper, on the basis of a biophysical mean-field model, we investigate a typical absence epilepsy activity by introducing slow kinetics of GABAB receptors on thalamus reticular nucleus (TRN). We find that the region of spike and slow-wave discharges (SWDs) can be reduced greatly when we add the DBS to TRN. Furthermore, we systematically explore how the corresponding stimulation parameters including frequency, amplitude and positive input duration suppress the SWDs under certain conditions...

The autosomal dominant spinocerebellar ataxias (SCAs) are a diverse group of neurological disorders anchored by the phenotypes of motor incoordination and cerebellar atrophy. Disease heterogeneity is appreciated through varying comorbidities: dysarthria, dysphagia, oculomotor and/or retinal abnormalities, motor neuron pathology, epilepsy, cognitive impairment, autonomic dysfunction, and psychiatric manifestations. Our study focuses on SCA13, which is caused by several allelic variants in the voltage-gated potassium channel KCNC3 (Kv3...

Valproate (VPA) is an antiepileptic drug (AED) used for initial monotherapy in treating childhood absence epilepsy (CAE). EEG might be an alternative approach to explore the effects of AEDs on the central nervous system. We performed a comparative analysis of background EEG activity during VPA treatment by using standardized, low-resolution, brain electromagnetic tomography (sLORETA) to explore the effect of VPA in patients with CAE. In 17 children with CAE, non-parametric statistical analyses using sLORETA were performed to compare the current density distribution of four frequency bands (delta, theta, alpha, and beta) between the untreated and treated condition...

OBJECTIVE: Until now, it has been unclear if the three subsyndromes of adolescent-onset generalized genetic epilepsy (GGE) differ in long-term prognosis. Therefore, this study aimed to compare long-term seizure outcome in juvenile absence epilepsy (JAE), juvenile myoclonic epilepsy (JME), and epilepsy with generalized tonic-clonic seizures alone (EGTCS). METHODS: This retrospective study is based on the archive of an institutional tertiary care outpatient clinic for adult patients with epilepsy...

Electroencephalographic abnormalities may occur in autistic spectrum disorders (ASD) even in the absence of clinical seizures. These abnormalities may vary from nonspecific changes to epileptiform abnormalities and are more common compared to the overall population. The level of intelligence is a significant risk factor for epilepsy in ASD. However, the relation between the functionality of the individuals with autism and the electroencephalographic (EEG) abnormalities, and the clinical significance of these abnormalities still remain relatively unclear...

Various typical and atypical neurological manifestations can be seen as the initial symptoms of celiac disease (CD). We suggest that gluten toxicity is the most suspicious triggering risk factor for probable pathophysiological pathways of neurological involvement in atypical CD. The medical charts of 117 patients diagnosed with atypical CD were retrieved from a tertiary center in Ankara, Turkey. Eight patients reported as having neurologic manifestations as initiating symptoms were evaluated in detail. The initial neurological manifestations of CD in our study included atypical absence, which was reported first in this study, generalized tonic-clonic seizures, complex partial seizures, severe axial hypotonia and down phenotype, multifocal leukoencephalopathy, mild optic neuritis, attention deficit hyperactivity disorder, and short duration headaches...
