Filter by:One of the most important neurological consequences following Traumatic Brain Injury (TBI) is the development of post traumatic epilepsy (PTE). Nevertheless, there is still no effective therapeutic intervention to reduce the occurrence of PTE. In previous studies with animals models of epilepsy, the biperiden decreased the incidence and intensity of spontaneous epileptic seizures besides delaying their appearance. The aim of this study is the evaluation of biperiden as antiepileptogenic drug to prevent PTE and also the determination of side effects, evaluating its cost-effectiveness in patients with moderate and severe TBI.
To carry out the epidemiological investigation on epilepsy in Zhejiang Province, China, and then establish early comprehensive intervention to help patients with epilepsy to improve seizure control and the quality of life.
In this study, the single-cell transcriptome sequencing technology was used to study the transcriptome differences at the single-cell level in normal human brain, aging human brain, and epileptic brain.
Drug-resistant focal epilepsy (DRFE) is frequently associated with complications of varying severity that impair patient's quality of life. Among these complications, cognitive disturbances and especially episodic memory difficulties, play a determinant part. Episodic memory can be defined as a function that allows the mental reconstruction of a past life episode, through complex associative mechanisms that link the vivid experience to its context of occurrence, called encoding context. It is a dynamic cognitive function, which calls on a widely distributed cerebral network, mainly involving the medial temporal lobe, particularly the hippocampus. Epilepsy could have a specific impact on this crucial network, disrupting the binding mechanisms between the experienced events and their encoding context, which are essential for efficient memory. Although patients with DRFE frequently demonstrate memory impairment as assessed by standardised neuropsychological tests, it only imperfectly reflects their difficulties. As a matter of fact, despite a subjective memory complaint, about 20% have no memory impairment on these tests, resulting from a phenomenon called accelerated long-term forgetting (ALF). ALF is indeed characterised by normal performance on standardised neuropsychological tests involving retention delays of 20-30 minutes, but disabling memory complaint and abnormally marked forgetting within hours or days that follow the learning period. This phenomenon is widely described at the conceptual level, but remains difficult to measure in daily practice, at least partly due to methodological limits. Thus, the validated tools available in clinical routine are poorly adapted to the complexity and the associative dimension of memory networks. There is therefore a clinical need for a specific assessment tool that would be able to detect ALF, in order to better quantify it and to enable the appropriate care of patients suffering from DRFE. The aim of the EPIMNESIE study is to evaluate the diagnostic capacity of a behavioural associative memory task, based on the analysis of encoding and consolidation mechanisms, in order to measure ALF. In this prospective study, 40 patients with DRFE and 40 healthy subjects will be proposed to complete a new associative memory task involving a learning phase and two recall sessions which will take place at 30 minutes and 72 hours after the learning phase.
To evaluate the efficacy, safety and tolerability of cenobamate as adjunctive treatment of refractory focal epilepsy
Many studies have reported a disparity in medication adherence among epileptic patients. In this population, Medication Possession Ratio (MPR) is an index of medication adherence. MPR is defined as the ratio of the number of days of treatment delivered to the number of days in the period of interest. No-adherents patients are defined by a MPR of less than 80% , in whom an increase in seizures and the rate of hospitalization can be observed. A pharmacist-led intervention and medication information to epileptic patients could improve patient medication adherence to antiepileptic drugs, and possibly decrease the frequency of seizures, hospitalizations and the health costs generated by these hospitalizations. This intervention could also improve patient knowledge about their medications. The aim of this study is to evaluate the effectiveness of a pharmacist-led intervention on medication adherence of epileptic patients with the MPR. Secondary objectives include the comparison of medication adherence with health insurance score, the evaluation of patients knowledges about their medications, community pharmacists' satisfaction about community hospital network, the comparison of the seizure free patient rate and the comparison of the rate of patient in whom seizure have decreased by 50%
The objective of this study is to assess the efficacy, safety, and pharmacokinetics of NBI-921352 as adjunctive therapy for seizures in subjects with SCN8A Developmental and Epileptic Encephalopathy Syndrome (SCN8A-DEE).
The purpose of this study is to understand how ketamine brings about dissociative symptoms.
Advance in stroke treatment have resulted in a dramatic reduction in the stroke mortality, however, the number of stroke survivors living with morbidity has increased significantly. As we know, post-stroke epilepsy has been identified as a significant clinical issue in stroke survivors and stroke is the most common cause of epilepsy in older adults and for patients aged more than 65, post-stroke epilepsy accounts for 30-50% of new-onset seizures. Our previous study documented seizures during stroke presentation and during hospitalization would worsen the overall morbidity and mortality, suggesting the importance of awareness in seizure care in acute ischemic stroke. As current studies only focus on anti-seizure/anti-convulsion after the appearance of late-onset seizures, without the intervention of the epileptogenesis, it is important to develop a potential novel prophylactic treatment on patients with acute severe stroke to prevent from late occurrence of seizures and epilepsy. We have previously done researches on the medications that might have potential of anti-epileptogenesis in pilocarpine-induced animal models, supporting the concept of antiepileptogenesis, giving intervention immediately following a brain insult. The results of some earlier anecdotal reports or small studies on prophylactic use of antiepileptic drug (AED) therapy in stroke, either hemorrhagic or ischemic strokes, remain inconclusive. There still lacks a well-established case-control study on prophylaxis of post-stroke epilepsy, with the early intervention of AED therapy with potential of anti-epileptogenesis in the phase of epileptogenesis. Based on our clinical experience, and laboratory researches, we have noted two non-conventional AEDs, levetiracetam (LEV) and perampanel (PER) with potential of anti-epileptogenesis. It is justified to evaluate if early administration of LEV or PER in patients with acute major stroke as a prophylactic therapy could hamper the development of epileptogenesis and the later post-stroke epilepsy. We aim to conduct a randomized case-control study to evaluate if early prophylactic introduction of low dose AED therapy (LEV or PER) in patients with moderate to severe middle cerebral artery infarct, could prevent the development of post-stroke epilepsy (primary prevention).
