The purpose of this study is to determine whether BHV-7000 is effective in the treatment of refractory focal epilepsy.
The purpose of this study is to precisely delineate human brain networks that modulate respiration and identify specific brain areas and stimulation techniques that can be used to prevent seizure-induced breathing failure.
The purpose of this research is to see to what extent electrical stimulation applied to the scalp (transcranial direct current stimulation or tDCS) can reduce the number and intensity of epileptic seizures.
Ιn the present study (BIOEPI), the following three hypotheses will be investigated: 1. The proposed TMS-EEG / EMG protocol (which includes software for calculating the cerebral cortex stimulation threshold) in combination with advanced signal analysis and data mining methods will allow the detection of the effect of antiepileptic drugs (AED) with different mechanisms of action (lacosamide & brivaracetam) in the Central Nervous System under healthy and pathological conditions (Epilepsy). 2. AED-induced changes in selected TMS-EEG / EMG features predict the clinical response of individual epileptic patients to AED. 3. AED-induced changes in selected TMS-EEG / EMG features may predict cognitive side effects.
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.
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.
Multicentre cross-sectional study with prospective recruitment comparing the detection rate of lesions on brain MRI without and with quantitative volumetry and T1 relaxometry information during the management of children with suspected focal epilepsy.
This project will test the accuracy of a novel diffusion-weighted magnetic resonance imaging (DWMRI) approach using a deep convolutional neural network (DCNN) to predict an optimal resection margin for pediatric epilepsy surgery objectively. Its primary goal is to minimize surgical risk probability (i.e., functional deficit) and maximize surgical benefit probability (i.e., seizure freedom) by precisely localizing eloquent white matter pathways in children and adolescents with drug-resistant focal epilepsy. This new imaging approach, which will acquire a DWMRI scan before pediatric epilepsy surgery in about 10 minutes without contrast administration (and also without sedation even in young children), can be readily applied to improve preoperative benefit-risk evaluation for pediatric epilepsy surgery in the future. The investigators will also study how the advanced DWMRI-DCNN connectome approach can detect complex signs of brain neuronal reorganization that help improve neurological and cognitive outcomes following pediatric epilepsy surgery. This new imaging approach could benefit targeted interventions in the future to minimize neurocognitive deficits in affected children. All enrolled subjects will undergo advanced brain MRI and neurocognitive evaluation to achieve these goals. The findings of this project will not guide any clinical decision-making or clinical intervention until the studied approach is thoroughly validated.
