Filter by:The purpose of this trial is to evaluate the efficacy, safety, and pharmaco-economics of Lacosamide Tablet as first add-on therapy for uncontrolled focal onset epilepsy ,invetigating effects of lacosamide Tablet on cognitive function of children and anxiety and depression of adults with focal onset seizures In real-world clinical setting
Phase 2A single-arm exploratory clinical study in up to 12 adult subjects aged 18 and older with primary glioma, IDH1 mutation, and uncontrolled focal-onset seizure activity to determine the potential efficacy, safety and pharmacokinetics of ES-481 as adjunctive therapy in glioma-associated epilepsy and to assess for potential anti-tumorigenic effects.
A prospective prevalence study recorded that up to 50% of adult patients with newly diagnosed epilepsy had at least one cognitive impairment before initiation of antiepileptic drug (AED). Multiple factors exist and interact in the same patient. Cognitive impairments may affect psychiatric (loss of self-esteem, anxiety, depression) and social status (e.g., vocational aptitude, educational). These factors in turn influence cognitive abilities in a triangular and bidirectional relationship. In addition, the type of epilepsy, development in childhood or cerebral ageing, antiepileptic treatments (AED, surgery) and etiology also have an impact on cognitive performances. The burden of these factors differs from patient to another and must be determined individually. Longitudinal follow-up seems to be crucial because it will allow us to highlight the change in the cognitive profile of newly diagnosed patients over time. The main objective is to compare the prevalence of cognitive impairment in patients with newly diagnosed epilepsy prior to the initiation of AED with healthy subjects matched on age, sex, manual laterality and socio-educational level. But also to compare the longitudinal evolution of the cognitive profile of patients with healthy controls (0 to 10 years) to determine, among the age of onset seizures, their etiology, the syndrome, the sex, the socio-educational level and the cognitive reserve, which one are related to the severity of cognitive disorders.
Epilepsy surgery is effective for refractory epilepsy, particularly focal epilepsy, but is still underutilized worldwide. In the United States, the annual percentage of surgical procedures for refractory epilepsy was low (range: 0.35%-0.63%) from 2003 to 2012. Fear associated with the risks of invasive procedures may be the reason for the cautious attitude towards epilepsy surgery. Therefore, the risks of epilepsy surgery in the modern age need to be evaluated thoroughly and precisely to improve epilepsy surgery outcomes. The safety of epilepsy surgery has been confirmed in several studies. Studies on this topic with large sample sizes (> 500 patients) were either multicenter or covered a long study period. In addition, high-resolution magnetic resonance imaging (MRI) was not used in the early stage in these studies. Differences in medical environment among epilepsy centers and advancements in presurgical evaluations and surgical techniques over time may have caused heterogeneity and biases, thereby limiting the quality of these studies. Over the past two decades, there was no large-scale studies on post-epilepsy surgery complications performed at a single center. Moreover, surgery-related complications are seldom graded according to severity. Especially, the risk factors for these complications remain unclear.
This retrospective study aimed to develop a new approach for automatic localization of epilepsy foci in children with epilepsy.
the investigators have recently shown that patients with drug-resistant temporal lobe epilepsy who have undergone brain surgery targeting the medial temporal lobe structures were more likely to develop tinnitus postoperatively. This discovery of a vulnerability to tinnitus associated with medial temporal lobe surgery to eliminate drug-refractory epileptic seizures provides a new clinical model of tinnitus, targeting temporal lobe regions as generators or mediators of this hearing disorder. The objective of this project is to study the impact of tinnitus on the cognitive, emotional, psychoacoustic and cerebral functioning associated with this hearing disorder, and to clarify the pathophysiology of tinnitus by comparing different groups of individuals with tinnitus (surgical epileptic patients or non-surgical ORL patients) to matched tinnitus-free groups (surgical tinnitus-free cases and healthy controls volunteer).
Sleep slow waves (SSW) and the pathophysiological mechanisms of spike generation in patients with epilepsy are tightly linked. SSW are cortically generated oscillations (~1 Hz) alternating between a hyperpolarized down-state (neuronal silence) and a depolarized up-state (neuronal firing). It has been shown experimentally that with increasing synchrony of slow neuronal oscillations, spike wave occurrence is facilitated. Auditory stimulation applied in correspondence to the SSW "up-phase" may increase the amplitude of the following SSW. Contrarywise, tones applied at the SSW "down-phase" may have a disruptive effect on SSW. Participants: Patients with epilepsy with epileptic discharges in their sleep EEG, as well as healthy controls Objective: Characterizing the effects of down-phase-targeted auditory stimulation on behavior and sleep EEG characteristics and determine whether the changes in sleep EEG characteristics are associated with the changes in behavior and wake EEG characteristics.
The purpose of the study is to evaluate the long-term safety and tolerability of brivaracetam.
This is a Phase 2a, Randomized, Double-Blind, Placebo-Controlled Study with cross-over to Evaluate the Efficacy, Safety, and Pharmacokinetics of ES-481 in Adult Patients with Drug Resistant Epilepsy
The investigators plan to enroll individuals with medical temporal lobe epilepsy who are undergoing surgical workup with clinically implanted intracranial electrodes. The study intends to administer computerized memory tasks and stimulation during the intracranial Electroencephalography (EEG) monitoring period.
