The Hyperpolarization-activated Cyclic Nucleotide-gated (HCN) channels are highly expressed in the Central Nervous Systems, where they are responsible for the Ih current. Together with specific accessory proteins, these channels finely regulate neuronal excitability and discharge activity. In the last few years, a substantial body of evidence has been gathered showing that modifications of Ih can play an important role in the pathogenesis of epilepsy. However, the extent to which HCN dysfunction is spread among the epileptic population is still unknown...

BACKGROUND: Temporal lobe epilepsy (TLE) is the most common form of focal epilepsy. Recent studies have demonstrated that ultrasound stimulation can inhibit spontaneous recurrent seizures and improve behavioral outcomes for rodents with TLE. However, the exact underlying mechanism for inhibition of TLE via ultrasound stimulation remains unknown. METHODS: In this study, low-intensity pulsed ultrasound stimulation (LIPUS) and low-intensity continuous ultrasound stimulation (LICUS) and concurrent local field potentials (LFPs) in the CA3 field of the hippocampus were recorded in the kainite-induced mouse model of TLE...

OBJECTIVE: To assess the long-term safety and efficacy of eslicarbazepine acetate (ESL) monotherapy in adults with focal seizures (FS). METHODS: Study 050 was a long-term, multicenter, open-label (OL) safety extension of two conversion-to-ESL monotherapy studies in adults with refractory FS. After participating in Study 045 or 046, patients started on ESL 1600 mg once daily (QD) (or 1200 mg if they previously had a dose reduction), and could adjust the dose 400 mg/week to a dose between 800-2400 mg QD...

Infection with Human Herpesvirus-6 (HHV-6) has been associated with different epilepsy syndromes, including febrile seizures and status epilepticus, acute symptomatic seizures secondary to encephalitis and temporal lobe epilepsy. This neurotropic DNA virus is ubiquitous and primary infection occurs in up to 80% of children by age two years. While two viral variants have been identified, HHV-6B is the one that has been primarily linked to disease in humans, including epilepsy. After initial viremia, the virus can establish chronic latency in brain tissue, peripherally in tonsils and salivary glands and infect several different cell lines by binding to the complement regulator CD-46...

Chronic Prostatitis/Chronic Pelvic Pain Syndrome (CP/CPPS) is a result of interplay between psychological, immune, neurological and genetic factors, manifested by variety of urological, as well as brain-related symptoms. However, its relation with brain excitability has not been addressed. herefore, our aim was to assess susceptibility to seizures in rats with CP/CPPS. We induced CP/CPPS in adult rats by intraprostatic injection of 3% λ-carrageenan. Sham operated rats served as controls (0.9% NaCl, Sham). On day 7 upon injection, rats were treated with lindane (4 mg/kg) and observed for convulsive behavior (seizure incidence, latency and severity) and EEG manifestations (number and duration of ictal periods)...

Dietary supplements, herbal medicines, and other foods may affect the pharmacokinetics and/or pharmacodynamics of carbamazepine (CBZ), which may possibly lead to potential drug-drug/herb-drug interactions, as CBZ has a narrow therapeutic window. Sinapic acid (SA) is a bioactive phytoconstituent used as a dietary supplement for the treatment of epilepsy. This study determined the effects of SA on the pharmacokinetics of CBZ and proposed a possible interaction mechanism in twenty-four male wistar rats (180-210 g)...

PURPOSE: Deep brain stimulation (DBS) of the anterior nucleus of the thalamus (ANT) is a promising treatment for refractory epilepsy; however, it remains challenging to successfully target the ANT. The results of Medtronic Registry for Epilepsy (MORE) supported a frontal transventricular(TV) compared to frontal extraventricular (EV) lead trajectory for ANT DBS may have better coverage of the ANT. Here we report the safety and targeting efficacy of a novel, posterior parietal extraventricular (PEV) approach to the ANT...

Studies of chronic epilepsy show pathological high frequency oscillations (HFOs) are associated with brain areas capable of generating epileptic seizures. Only a few of these studies have focused on HFOs during the development of epilepsy, but results suggest pathological HFOs could be a biomarker of epileptogenesis. The Epilepsy Bioinformatics Study for Antiepileptogenic Therapy" (EpiBioS4Rx) is a multi-center project designed to identify biomarkers of epileptogenesis after a traumatic brain injury (TBI) and evaluate treatments that could modify or prevent the development of post-traumatic epilepsy...

Status epilepticus (SE) is a serious, life-threatening condition requiring immediate care to prevent neuronal injury and long-term functional deficits. SE is modeled in rodents by systemic injection of chemoconvulsants such as pilocarpine, which induces EEG and behavioral activities similar to what seen in humans. Combined injection of diazepam and ketamine is commonly used to terminate SE in rodents but, to date, no study has analysed the EEG activity and behavior during SE and after diazepam + ketamine administration...

The Fourteenth Eilat Conference on New Antiepileptic Drugs and Devices (EILAT XIV) took place in Madrid, Spain from May 13th to 16th 2018. Again, presentations on new medical devices and neuromodulation and discussions on device-related regulatory aspects were included in the programme. The virtual special issue on "neuromodulation" summarises the presentations focusing firstly, on the pre-clinical developments and the difficulties of clinical trial designs for neuromodulatory therapies, including vagus nerve stimulation (VNS) and Brain-Responsive Neurostimulation (RNS), and the use of transcutaneous vagus nerve stimulation (tVNS) as a potential screening tool for determining the efficacy of neuromodulatory treatments in individual patients; secondly, on wearable devices for seizure monitoring through indices of peripheral sympathetic nervous activity, the use of such devices in combination with biofeedback for the treatment of epilepsy, and its potential for improving epilepsy specialist services, particularly in remote areas...

Recognition of insular epilepsy may sometimes be challenging due to the rapid speed at which insular seizures can spread throughout the cortex via extensive connections to surrounding cortices. The spectrum weighted adaptive directed transfer function, a multivariate causality-based effective connectivity measure, was applied to intracranial electroencephalography recordings to identify generators of seizure activity. A non-parametric test based on surrogate data testing was used to validate statistical significance of causal relations...

Generalized seizures trigger excessive neuronal firing that imposes large demands on the brain glucose/lactate availability and utilization, which synchronization requires an integral mitochondrial oxidative capability. We investigated whether a single convulsive crisis affects brain glucose/lactate availability and mitochondrial energy production. Adult male Wistar rats received a single injection of pentylentetrazol (PTZ, 60 mg/kg, i.p.) or saline. The cerebrospinal fluid (CSF) levels of glucose and lactate, mitochondrial respirometry, [14 C]-2-deoxy-D-glucose uptake, glycogen content and cell viability in hippocampus were measured...

Epileptic spasms during infancy (infantile spasms) represent a serious treatment and social problem despite their rare occurrence. Current treatments include hormonal therapy (adrenocorticotropin-ACTH or corticosteroids) or vigabatrin (per se or in the combination). These treatments are partially effective and with potentially significant adverse effects. Thus, the search for new effective drugs is warranted. We tested efficacy of a novel fusion peptide AQB-565 developed by Aequus Biopharma in a model of infantile spasms consisting of prenatal exposure to betamethasone and repeated postnatal trigger of spasms with N-methyl-d-aspartic acid (NMDA)...

The last decade saw impressive advances not only in the discovery of gene mutations causing epilepsy, but also in unraveling the molecular mechanisms underlying the clinical manifestations of the disease. Increasing evidence is emerging that understanding these mechanisms is relevant for selection of the most appropriate treatment in the affected individual(s). The present article discusses the therapeutic implications of epilepsy-causing variants affecting a broad range of targets, from ion channels to genes controlling cellular metabolism and cell signaling pathways...

Wearable automated seizure detection devices offer a high potential to improve seizure management, through continuous ambulatory monitoring, accurate seizure counts, and real-time alerts for prompt intervention. More importantly, these devices can be a life-saving help for people with a higher risk of sudden unexpected death in epilepsy (SUDEP), especially in case of generalized tonic-clonic seizures (GTCS). The Embrace and E4 wristbands (Empatica) are the first commercially available multimodal wristbands that were designed to sense the physiological hallmarks of ongoing GTCS: while Embrace only embeds a machine learning-based detection algorithm, both E4 and Embrace devices are equipped with motion (accelerometers, ACC) and electrodermal activity (EDA) sensors and both the devices received medical clearance (E4 from EU CE, Embrace from EU CE and US FDA)...
