Filter by:Every year, thousands of patients worldwide with drug resistant focal epilepsy (DRE) undergo resective brain surgery with the aim of achieving seizure freedom. Despite technical advances over the last 50 years, the success rate of epilepsy surgery in terms of seizure freedom has not greatly improved, remaining overall at around 50%. Depending on features of individual cases, presurgical evaluation includes a first phase of non-invasive data including video-EEG recordings, magnetoencephalography, structural and functional neuroimaging and neuropsychological evaluation. If these investigations do not allow adequate localization of likely region of seizure organization in the brain (the epileptogenic zone, EZ), then a second invasive phase using intracerebral EEG recording may be necessary (stereoelectroencephalography, SEEG). Interpretation of SEEG remains difficult in many cases, in particular since seizure onset is often characterized by discharges that very rapidly involve several distinct brain regions. No reliable measuring instrument currently exists to combine the various prognostic factors for a given patient. This leads to great uncertainty on an individual scale in predicting the effects of surgery. The mapping of epileptic networks in patients with DRE is an innovative scientifically-validated and clinically-tested method to significantly improve accuracy of SEEG and presurgical interpretation and guide surgical strategies in patients with DRE. Therefore, the investigators developed the Virtual Epilepsy Patient software. Retrospective study already demonstrated the pertinence of this approach in improving the anatomical mapping of epileptogenic networks. Now, the investigators aim to prospectively demonstrate the role of VEP during presurgical evaluation of DRE patients
This study is designed as a pilot test of the YESS! web-based intervention for adolescents with epilepsy. One hundred twenty participants will be given access to the intervention for a period of eight weeks. The investigators are testing the feasibility and acceptability of the the study procedures, measures and of the intervention itself. The study also evaluats the potential for impact on the users.
Gliomas are primitive brain tumors frequently associated with epilepsy. In a significant number of these patients epilepsy is resistant to antiepileptic drugs. There are currently no recommendations for the management of these drug-resistant epilepsies associated with glioma. In addition, few studies have addressed the subject and no treatment appears to be superior to others in the literature for this indication. In addition, many antiepileptic drugs pose problems of tolerance or interaction with chemotherapy in these patients. Fundamental studies on glioma-associated epilepsies have shown that there is a major dysregulation of glutamatergic systems involved in epileptogenesis and tumor growth. Targeting this glutamatergic system seems particularly interesting from a physiopathological point of view. Perampanel is a recent antiepileptic treatment with a novel mode of action targeting AMPA glutamate receptors. It has been shown to be effective in patients with drug-resistant epilepsies. He has demonstrated his tolerance in these patients. He has obtained a marketing authorization and is therefore used in routine epileptology without serious problems of tolerance being reported. It is neither an inducer nor an enzyme inhibitor, avoiding the problems of interaction with chemotherapy and is used in a daily dose facilitating compliance. Therefore, there may be specific antiepileptic efficacy of perampanel in patients with glioma. Nevertheless, the only current data is limited to a retrospective study of 12 patients. The objective of this protocol is to evaluate the efficacy and safety of perampanel in patients with glioma with drug-resistant epilepsy. a prospective randomized study with two parallel arms: antiepileptic combination therapy with perampanel and antiepileptic combination therapy without perampanel (free choice of the practitioner). The main criterion of judgment will be the decrease of the monthly frequency of crisis. Secondary endpoints will assess tolerance, efficacy on responder rate (at least 50% decrease in seizure frequency), seizure severity (secondary generalization, loss of consciousness), and quality. patients' lives (quality of life questionnaires, side effects and anxiety / depression). The duration of participation per patient will be 23 weeks (6 weeks of baseline, 5 weeks of titration and 12 weeks of maintenance). The recruitment period will be 3 years. Investigators plan to recruit 120 patients. In the context of no recommendation in the management of these patients, superior efficacy of perampanel compared with other antiepileptic drugs is expected. This would allow targeted treatment in this population and confirm the tolerance of this treatment in these patients.
The main aim is to assess the long-term safety and tolerability of soticlestat when used along with other anti-seizure treatment. Participants will receive soticlestat twice a day. Participants will visit the study clinic every 2-6 months throughout the study. Study treatments may continue as long as the participant is receiving benefit from it.
This is a pilot study. The Investigators propose a pilot randomized, parallel-group, controlled trial comparing the GoToSleep program (GTS) and controls on change in Insomnia Severity Index (ISI) from baseline to week 8 in adults with epilepsy and moderate-to-severe insomnia. Adults with epilepsy and moderate-to-severe insomnia symptoms (ISI ≥15) 17 will be identified using data collected as part of routine clinical care in the adult epilepsy clinic. All subjects will be provided a consent form describing the study and provided sufficient information to make an informed decision. After a screening visit, subjects meeting study criteria will be randomized to the computerized cognitive behavioral therapy for insomnia (CCBT-i) using the GoTosleep (GTS) or the control group. Both groups will receive a sleep hygiene handout that is standard of care in the treatment of insomnia. All subjects will be contacted by phone every 2 weeks during the intervention to address questions related to sleep hygiene instructions and use of the CCBT-i in the GoTosleep (GTS) group. All subjects will complete a series of sleep related patient reported outcomes including the ISI at baseline 8 weeks post randomization and maintain a diary recording of seizures and sleep periods. Those randomized to CCBT-i will complete a questionnaire at week 8 assessing barriers to CCBT-i. Subjects randomized to the control group will be offered access to the GoTosleep (GTS) at no charge at the end of the study (week 8).
Alzheimer disease is the most common of the neurodegenerative diseases. Epilepsy and sleep wake disorders are co-morbid conditions of Alzheimer disease. The investigators propose a prospective study using long-term EEG monitoring in combination with polysomnography to determine prevalence of epilepsy and sleep wake disorders in Alzheimer disease, and correlate these findings with clinical data, Alzheimer disease biomarkers and imaging studies (MRI and amyloid/tau-PET). In selected patients, the investigators will perform EEG studies with foramen ovale electrodes. The ultimate goal is to improve the outcome of patients with Alzheimer disease by early treatment of epilepsy and restoring sleep-wake disturbances.
The primary purpose of the study is to assess the pharmacodynamic (PD) activity of E2730 as measured by suppression of epileptic photoparoxysmal response (PPR) in the participant's most sensitive eye condition in participants with photosensitive epilepsy.
The aim of this cross-sectional study is to investigate the level of stress and quality of life in parents of children with developmental disabilities (Down syndrome, autism spectrum disorder, pervasive developmental disorder, cerebral palsy) and parents of children chronic diseases (diabetes mellitus type 1, epilepsy, asthma) compared to parents of healthy children. The investigators will analyze the level of stress, quality of life, self-esteem, optimism, resilience, happiness, stigmatization, depression, anxiety, sleep quality, parenting challenges and some physiological indicators of the stress such as level of cortisol and heart rate variability. Also, the investigators will measure Advanced Glycation End products (AGEs) in the skin. The investigators assume that parents of children with developmental disabilities and chronic diseases have higher level of stress and lower quality of life compared to the parents of healthy children.
This study will investigate whether a Vagal Nerve Stimulator (VNS) causes measurable desynchronization and reduces epileptiform activity, such as spikes and seizures, in electrocorticograms (ECOGs) recorded by a Responsive Neurostimulator (RNS) in patients who have both devices implanted. Specific aims of the study: 1. Evaluate the change in frequency of epileptiform discharges during active VNS stimulation compared to interstimulation baseline periods 2. Evaluate the change in frequency of seizures during active VNS stimulation compared to interstimulation baseline periods 3. Evaluate the change in the number of RNS activations during active VNS stimulation compared to interstimulation baseline periods 4. Evaluate the change in synchronization of background ECoG (electrocorticogram) during VNS stimulation compared to interstimulation baseline periods.
Epilepsy is one of the most common and frequently encountered neurological conditions that impose a huge burden on the healthcare systems. Despite the abundance of antiepileptic drugs (AEDs) available, 30% of people continue to have seizures even after long-term therapy of 6-8 years. This group of people requires a more aggressive treatment since monotherapy, the first choice scheme, is not sufficient to control seizure and its complications, multiple drug therapy or polytherapy often results in the culmination of unwanted effects. The need for an add-on AEDs with a good safety profile is of utmost importance.The beneficial effects of melatonin on sleep, its wide safety window, and its ability to cross the blood-brain barrier have the potential to improve the quality of life in seizure patients. Various animal studies have suggested that melatonin receptors are the potential targets for anticonvulsant drug development. In animal studies, melatonin was found to suppress generalized seizure and seizure susceptibility and it also has neuroprotection and synapse modulating properties. Some clinical trials mostly on paediatric population also found that melatonin can improve the clinical outcome in epilepsy. Therefore, we have planned to conduct a randomized, add-on placebo-controlled clinical trial on the effect of melatonin on seizure outcome, neuronal damage and quality of life in adult patients with generalized seizure.
