Filter by:The overarching goal of this exploratory research is to understand the dynamic and flexible nature of speech processing in the human supratemporal plane. The temporal lobe has long been established as a region of interest in the speech perception and processing literature because it contains the auditory cortex. More recently, research has localized the supratemporal plane as an area that exhibits response specificity to acoustic properties of complex auditory signals like speech. The supratemporal plane, comprised of Heschl's gyrus, the planum polare, and the planum temporale, is capable of the rapid spectrotemporal analysis required to map acoustic information to linguistic representation. Neural activity in this area, however, is rarely studied directly because it is difficult to access with non-invasive measures like scalp electroencephalography (EEG). Capitalizing on the unique opportunity to access these areas via routine clinical stereoelectroencephalography (sEEG) in a patient population, this study seeks to understand how cortical responses reflect the diagnosticity of two acoustic-phonetic dimensions of interest and how responses rapidly and flexibly adapt to changes in listening demands. Examining how neural response to voice onset time (VOT) and fundamental frequency (F0) modulates as a function of perceptual weight carried in signaling phoneme categories, and identifying how changes in listening context shift perceptual weight, will provide invaluable data that indicates how speech processing flexibly adapts to short-term acoustic patterns.
Coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has already rapidly spread around the world as a pandemic after its first report in Wuhan, China on December 12th 2019 ( Holshue ML et al .,2019 ). As of December 27th 2020, there were more than 79.2 million confirmed cases and more than 1.7 million deaths caused by COVID-19 worldwide (WHO,2020). Migraine& tension headacheare considered one of the most disabling chronic neurological diseases, and patients with migraine or tension headache are particularly vulnerable to drastic negative impacts of the pandemic. From heightened levels of psychosocial stress, social isolation , disruption of sleep and dietary habits ,to several COVID-19-specific concerns. Normally, people with epilepsy (PWE)patients are very sensitive to different factors such as physical or emotional disturbances or environmental and lifestyle changes.Many factors can increase the risk of seizures,i.e., illness and fever, stressful events, sleep deprivation,changes in antiepileptic drugs (AED),use of proconvulsive treatments,to name a few.Some are unavoidable during a sociosanitary crisis like that currently being experienced. Because of the rapid increase of infections, Government enacted a national state of emergency, limiting public mobility and compelling home confinement and social isolation. This national lockdown, in addition to the direct effects of COVID-19, have dramatically altered the lifestyle and normal routines of the entire population.Therefore, in addition to the risk of neurological involvement that COVID-19 itself has, during the pandemic,different circumstances may negatively impact on seizure control in PWE.
The purpose of the proposed investigation is to carry out a pilot study of add-on perampanel (Fycompa) in women with perimenstural (C1) catamenial epilepsy. Perampanel, a noncompetitive AMPA receptor antagonist, is uniquely positioned to decrease progesterone receptor mediated excitotoxicity. This mechanism of action would allow a novel use of perampanel as an effective treatment of C1 catamenial epilepsy.
The purpose of this study is to test microelectrodes in intracranial monitoring to see if they will provide novel information on the epileptic potential of the implanted brain tissue. A secondary objective is to investigate the activity of single neurons during specific cognitive tasks.
Tuberous sclerosis complex (TSC), affecting 1 in 6.000 live births, is characterized by the development of multisystem tumors. Seizures are frequent up to 80% of individuals. They usually start in infancy and are often drug resistant, with a high risk of intellectual disability and autism spectrum disorders. In animal models, preventive treatment before seizures onset significantly decreased the risk of epilepsy as well as associated comorbidities. EPISTOP randomized clinical trial (RCT) aimed to validate the effect of preventive therapy in patients with TSC diagnosed before clinical seizures with abnormal EEG, versus late standard therapy of epilepsy, administered after the seizures onset. This preventive therapy resulted in a significant better outcome in seizures and co-morbidities. However, this trial included few patients and did not allow to fully explore the secondary endpoints. Our goal within EPISTOP-IDEAL project is to benefit from joining clinical expertise of EPISTOP project and experts from IDEAL EU project on methodologies for CTs in small populations in order to consolidate the results of EPISTOP CT using uncertainty evaluation of the existing data of randomized and observational arms and adding important information from external data collected after EPISTOP ended. This collaboration aims to an optimal use of all available data (RCT, observational and external data collected with the same protocol). The goal is to demonstrate the added value of these methodologies in TSC CT and to their further use to rare epilepsies, and other rare diseases.
Laser Induced Interstitial Thermal Therapy (LITT) is a "minimally invasive" procedure that uses the heat generated by a laser light (65°) to destroy brain lesions by coagulation leading to lesion necrosis under real-time MRI monitoring. The laser optical fiber is implanted into the lesion using stereotaxy. This technique, which can be performed under local anesthesia and on an outpatient basis, proved its efficacy and safety in the treatment of brain metastases for the first time in the world in 2006 (A. Carpentier et al, 2008, 2011). Since then, more than 5,000 patients have been treated in the USA, including for epileptogenic lesions (FDA device and CE cleared). Our goal is to evaluate LITT on lesions with drug-resistant epilepsy for which surgical resection is impossible. No therapeutic trial evaluating LITT in this indication has been performed to date. It is therefore necessary to study its feasibility and tolerance.
ABSTRACT Background and Aims: To determine the diagnostic performance of the epilepsy and intellectual disability panel used in the pediatric population, starting in June 2019, at the Regional University Hospital Center of Nancy, France. Design: An observational and retrospective study, at the Regional University Hospital Center of Nancy, France. Materials and Methods: Pediatric patients who underwent genetic analysis with the epilepsy-intellectual disability gene panel. All of these patients were either epileptic or had intellectual disability, or both, of undetermined etiology. Results: We included 69 patients in this study. We identified causative mutations in 46.4% (32 of 69 patients) of this cohort after the gene panel and 52.2% (36 patients) including positive results after realization of the Clinical Exome Solution.
The aim of this study is to investigate the frequency of sleep problems in epileptic children and their caregivers.
The PRECISION-study offers a non-invasive, curative intervention for drug-resistant localised epilepsy patients who are not eligible for surgery. The intervention will consist of a single LINAC based SRT treatment and is given by the radiation-oncologist after detailed localisation of the epileptogenic zone with the neurologist, radiologist and neurosurgeon. This intervention will make curative-intent treatment possible where this could otherwise not be given and is a non-invasive and non-competitive alternative to epilepsy surgery. It is expected that the health costs for this curative treatment will not exceed standard treatment, such as lifelong medication and neuromodulation.
The most prevalent neurological disorder with also immense burden of disease, epilepsy, is in over 30 percent of patients difficult to treat. The ideal treatment regime would give complete control of disease in an early stage, not only for patient well-being, but also to prevent the onset of persistent pathologic epileptic networks in the brain. The first step in treatment is the trial, and error, of multiple anti-epileptic drugs (AEDs), while invasive brain stimulation (BS) techniques with network modulating properties are saved as a last resort. The investigators hypothesize that pharmacotherapeutic treatment of epilepsy can be more successful after "priming" (preparing) the brain using BS as a short-term neuromodulation treatment. The limitation of testing this hypothesis is the invasive aspect of the most used classic vagal nerve stimulation (VNS) treatment for epilepsy, but the recent development of transcutaneous vagal nerve stimulation (tVNS) offered a possibility to combine chemical and electrical modulation in an earlier stage of disease, which is not tested before. The investigators want to determine the priming effect on the epileptic brain of tVNS, to make it more susceptible to add-on treatment with Brivaracetam (BRV), an AED. In addition, the investigators aim to visualize these changes in the brain because of priming, possibly altered network-organisation.
