Filter by:Epilepsy is the 3rd neurological pathology after migraines and dementia syndromes with a high estimate of nearly 600,000 people affected in France. The disease is characterized by the repetition of epileptic seizures on the one hand, but also by the cognitive, behavioral, psychological and social consequences of this condition, especially when the epileptic disease is not stabilized. Epileptic patients feel a great deal of stress due to the unpredictability of the occurrence of seizures. Seizure detection is of great interest to bioinformatics researchers and to people with epilepsy and their caregivers. Recent advances in physiological sensor technologies and artificial intelligence have opened the possibility of developing systems capable of closely monitoring the frequency of epileptic seizures with a direct impact on therapeutic adaptations. This may eventually allow for seizure prediction and/or "seizure weather" (i.e., seizure forecasting) if there is a particular chronotype of seizure occurrence for a given individual. Currently, few devices have a sufficient level of evidence regarding their effectiveness to be recommended. Those that seem to be the most advanced are those that allow the identification of hypermotor seizures, including tonic-clonic generalized seizures and tonic-clonic secondary generalized focal seizures, mostly occurring at night. The latter represent only a small part of epileptic seizures. The objective of the present study is to build a real life database in order to develop a seizure detection algorithm. The recorded data will be heart rate via ECG and movement data via 9 variables measured on 3 axes x, y, z, with 3 sensors: accelerometer, gyroscope, magnetometer. These data will be collected using a connected patch available on the market (CE marking). At the same time, the patients will benefit from a long term video-EEG examination which will be annotated by the doctors and will be used as a gold standard for the identification of seizures in order to train the algorithm. This more complete base will be used to develop an algorithm previously developed from retrospective data.
Epilepsy is a disabling neurological disease that affects tens of millions of people worldwide. Despite therapeutic advances, about a third of these patients suffer from treatment-resistant forms of epilepsy and still experience regular seizures.All seizures can last and lead to status epilepticus, which is a major neurological emergency. Epilepsy can also be accompanied with cognitive or psychiatric comorbidities. Reliable seizures count is an essential indicator for estimating the care quality and for optimizing treatment. Several studies have highlighted the difficulty for patients to keep a reliable seizure diary due for example to memory loss or perception alterations during crisis. Whatever the reasons, it has been observed that at least 50% of seizures are on average missed by patients. Seizure detection has been widely developed in recent decades and are generally based on physiological signs monitoring associated with biomarkers search and coupled with detection algorithms. Multimodal approaches, i.e. combining several sensors at the same time, are considered the most promising. Mobile or wearable non invasive devices, allowing an objective seizures documentation in daily life activities, appear to be of major interest for patients and care givers, in detecting and anticipating seizures occurence. This single-arm exploratory, multicenter study aims at assessing whether the use of such a non-invasive, wearable device can be useful in a real life setting in detecting seizures occurence through multimodal analysis of various parameters (heart rate, respiratory and accelerometry).
The purpose of this research is to search for reproducible changes in a wide range of physical signals, including heart rate, muscle tone and activity and EEG before and at the onset of seizures in patients with epilepsy.

Adjusting hearing aid user's real ear performance by using probe-microphone technology (real ear measurement, REM) has been a well-known procedure that verifies whether the output of the hearing aid at the eardrum matches the desired prescribed target. Still less than half of audiologists verify hearing aid fitting to match the prescribed target amplification with this technology. Recent studies have demonstrated failures to match the prescribed amplification targets, using exclusively the predictions of the proprietary software. American Speech-Language-Hearing Association (ASHA) and American Academy of Audiology (AAA) have created Best Practice Guidelines that recommend using real-ear measurement (REM) over initial fit approach and also the recent ISO 21388:2020 on hearing aid fitting management recommends the routine use of REM. Still audiologists prefer to rely on the manufacturer's default "first-fit" settings because of the lack of proof over cost-effectiveness and patient outcome in using REM. There are only few publications of varying levels of evidence indicating benefits of REM-fitted hearing aids with respect to patient outcomes that include self-reported listening ability, speech intelligibility in quiet and noise and patients' preference. Our main research question is whether REM-based fitting improves the patient reported outcome measures - PROMs (SSQ, HERE) and performance-based outcome measures (speech-reception threshold in noise) over initial fit approach. An additional research question is whether REM-based fitting improves hearing aid usage (self-reported & log-data report). Eventually, the investigators will calculate the cost-effectiveness of REM-based fitting.
The X-TOLE2 Phase 3 clinical trial is a randomized, double-blind, placebo-controlled study that will evaluate the clinical efficacy, safety and tolerability of XEN1101 administered as adjunctive therapy in focal-onset seizures.
Pre-market Clinical Investigation whose primary purpose is to evaluate efficacy and effectiveness of self-fitting hearing aids
The main purpose of this study is to determine the maximum safe tolerated dose of LEV in the treatment of neonatal seizures. Our hypothesis is that optimal dosing of Levetiracetam (LEV) to treat neonatal seizures is significantly greater than 60mg/kg. This study will be an open label dose-escalation, preliminary safety and efficacy study. There will be a randomized control treatment component. Infants recognized as having neonatal seizures or as being at risk of developing seizures will be recruited and started on continuous video EEG monitoring (CEEG). Eligibility will be confirmed and consent will be obtained. In the first 2 phases of the study, neurologists will identify neonates with mild-moderate seizure burden (less than 8 minutes cumulative seizure activity per hour), appropriate for study with LEV, and exclude patients with higher seizure burden where treatment with PHB is more appropriate. Phase 3 of the dose escalation will only proceed if additional efficacy of LEV has been demonstrated in phases 1 and 2. In Phase 3 we will recruit neonates with seizures of greater severity up to 30 minute seizure burden/hour. This will make the final results of study more generalizable. If seizures are confirmed, enrolled subjects will receive 60mg/kg of LEV. Subjects whose seizures persist or recur 15 minutes after the first infusion is complete, subjects will then be randomized in the dose escalation study. Patients in the dose escalation study will be randomly assigned to receive either higher dose LEV or treatment with the control drug PHB in a 3:1 allocation ratio, stratified by site.

The purpose of this research is to determine whether BOTOX injections will reduce seizure frequency and severity. We chose to test its effects on epilepsy because epilepsy and migraine have common features so, are often treated with common drugs.
This project studies how 2-deoxy-glucose (2DG) pills are absorbed and distributed in people with epilepsy. 2DG is similar to glucose, the main energy source for the brain, but it cannot be used as energy. During seizures, neurons are at a very high metabolic state with huge glucose metabolism as glycolysis is accelerated to supply the high metabolic needs of a seizure. 2DG is taken up by cells but cannot be metabolized by the first enzyme in the glycolytic pathway, thus is stops, or "clogs up", glycolysis. Since brain metabolism is almost entirely dependent on glucose as an energy source, glycolysis is arrested and may stop seizures. It is hoped that 2DG will stop seizures by interfering with the brain's energy use. This is an open-label phase 2 study of the pharmacokinetics (PK), safety, and tolerability of 2DG administered orally to adult epilepsy patients. A 3-level 2DG dose escalation is planned in sequential cohorts of 3 subjects in each cohort with review of each cohort before proceeding to the next cohort. On the day of oral 2DG exposure, subjects will receive a single dose of 40 mg in the first cohort, a single dose of 60 mg in the second cohort, and two 60 mg doses (60 mg bid) in the third cohort. After 3 subjects have completed dosing at Dose Level 1 (40 mg/day), the safety and PK results will be reviewed. The Study Committee will determine if the next cohort should be enrolled at Dose Level 2 (60 mg/day). The same procedure will be repeated to determine if the next cohort should be enrolled at Dose Level 3 (60 mg bid = 120 mg/day). If the Study Committee determines that the most recent dose is not tolerated or that there are significant adverse events, the subsequent Dose Level will not be enrolled. A standard time-concentration curve will be constructed from the 2DG levels obtained from the PK blood draws. Parameters will be calculated for: time to maximum concentration (tmax), maximum concentration (Cmax), elimination rate, half-life (t1/2), AUC, and derived parameters. Statistical analysis will not be performed because of the small n, but this will nevertheless establish the PK profile of 2DG in people with epilepsy. The most important parameter will be the AUC which determines drug exposure.
