Filter by:Vagal nerve stimulation (VNS) can be indicated in patients with drug-resistant epilepsy who are not eligible for resective epilepsy surgery with responders rates about 50% (≥50% seizure reduction). At the moment, there is not a widely-accepted possibility to predict VNS efficacy in a given patient based on pre-implantation data, which can lead to unnecessary surgery and improper allocation of financial resources. The principal aim of PRECISE (PRediction of vagal nerve stimulation EfficaCcy In drug-reSistant Epilepsy) study is to verify the predictability of VNS efficacy by analysis of pre-implantation routine EEG. The PRECISE relies on the results of our previous work, which developed a statistical classifier for VNS response (responders vs. non-responders) based on differences in EEG power spectra dynamics (Pre-X-Stim). PRECISE is designed as a prospective multicentre study in which patients indicated to VNS therapy will be recruited. Patients will be classified as predicted responders vs. predicted non-responders using pre-implantation EEG analyses. After the first and the second year of the study, the real-life outcome (responder vs. non-responder) will be determined. The real-life outcome and predicted outcome will be compared in terms of accuracy, specificity, and sensitivity. In the meantime, the patients will be managed according to the best clinical practice to obtain the best therapeutical response.
This is a pilot research study where language and working memory tasks will be used to study brain activities from children with epilepsy. Specifically for language assessment, a well-known MEG language protocol will be used and novel signal processing techniques will be applied. A widely utilized paradigm will be used to study memory function and adapt signal-processing techniques from previous literature for the processing and analysis of MEG signals collected during memory task. No treatment/intervention will be performed or evaluated in this pilot research study.
To demonstrate that the RNS System is safe and effective as an adjunctive therapy in individuals age 12 through 17 years with medically refractory partial onset epilepsy.
Mild malformation of cortical development with oligodendroglial hyperplasia in epilepsy (MOGHE) is a new entity frequently associated with refractory epilepsy and neurodevelopmental disorders. Recently, it has been associated to SLC35A2 (Solute Carrier Family 35 Member A2) brain mosaic pathogenic variants. In addition, patients with germline SLC35A2 pathogenic variants improve with galactose supplementation. Therefore, the investigators aim to elucidate whether d-galactose as an add-on treatment might improve epilepsy and developmental outcomes in patients with MOGHE.
Neurophysiologic evaluation of disorders of consciousness (DOC) patients in intensive care unit include late auditory evoked potentials. It allows the physicians to record cerebral responses of patients to auditory stimuli and in particularly to their own name (as the P3a response). Numerous studies try to improve the relevance of the auditory stimuli used in this paradigm and notably using more expressive stimuli. Here the investigators investigate the intracerebral correlates of the P3a responses recorded on the scalp with neutral and more expressive stimuli.
This project aims to conduct a pilot study based on the targeting of the epileptogenic zone previously localized very precisely by stereoelectroencephalography (SEEG). SEEG is used as part of the pre-surgical assessment. It consists, thanks to the intracerebral implantation of electrodes in the brain of patients, to perform an intracerebral electrophysiological recording and thus to precisely explore the epileptogenic regions. In order to study the neuromodulatory and therapeutic effects of tDCS on epileptic brains, non-invasive techniques for measuring electrophysiological brain activity such as magnetoencephalography (MEG) and high-resolution electroencephalography (HR EEG) will be used. Finally, since epilepsy is considered to be a disorder of brain functional networks associated with disturbed brain connectivity, the effects of tDCS on cortical excitability by studying the variations in functional connectivity induced by stimulation will be studied.
Deep Brain Stimulation (DBS) of the anterior nucleus of the thalamus (ANT) has been proposed in patients with severe intractable epilepsy. When used, the transventricular approach increases the risk of bleeding due the anatomy around the entry point in the thalamus. To avoid such a complication, the investigators used a transventricular microendoscopic technique.
This is a multiple site, randomized, double blinded parallel-group controlled study. The purpose of this study is to evaluate efficacy, safety, and tolerability of repeated, daily sessions with the STARSTIM device, which delivers transcranial cathodal direct current stimulation (tDCS). Subjects will be treated with STARTSTIM or sham device for 10 sessions over a 2-week period. The subjects will be followed for an additional 10 weeks post treatment. Quality of Life questionnaires and adverse events will be collected and evaluated.
This study aims to investigate the effect of a short-term prescription of ciprofloxacin on intestinal microbial pattern and seizure frequency of patients with drug-resistant epilepsy.
The purpose of this study is to use functional imaging to study the mechanisms of the anterior nucleus of the thalamus (ANT) deep brain stimulation (DBS).
