Biperiden Trial for Epilepsy Prevention
Brain Injury Traumatic ModerateBrain Injury Traumatic Severe1 moreOne of the most important neurological consequences following Traumatic Brain Injury (TBI) is the development of post traumatic epilepsy (PTE). Nevertheless, there is still no effective therapeutic intervention to reduce the occurrence of PTE. In previous studies with animals models of epilepsy, the biperiden decreased the incidence and intensity of spontaneous epileptic seizures besides delaying their appearance. The aim of this study is the evaluation of biperiden as antiepileptogenic drug to prevent PTE and also the determination of side effects, evaluating its cost-effectiveness in patients with moderate and severe TBI.
MELD as an Adjunct for SEEG Trajectories
EpilepsyEpilepsy3 moreEpilepsy is a disorder of the brain which is associated with disabling seizures and affects 100,000 people under 25. Many children with epilepsy also have a learning disability or problems with development. Although better outcomes occur in children who are successfully treated early for their epilepsy, 25% continue to have seizures despite best medical treatment. One potential treatment is a neurosurgical operation to remove parts of the brain that generate seizures. A proportion of these children have electrodes inserted into their brains as part of their clinical assessment, termed stereoelectroencephalography (SEEG), to help localise these regions. Subsequent surgery is not always successful - up to 40% of children will have ongoing seizures 5 years after surgery. The planning of where to place SEEG electrodes relies on experts (neurologists, neurophysiologists and neurosurgeons) using information from multiple sources, which are used to generate hypotheses about where the seizures are coming from. The main components are the patient's magnetic resonance imaging (MRI) scan and video-electroencephalography (EEG) recordings during seizures. Using this information, between 5-18 electrodes are implanted and the recordings continue for 5-15 days in hospital. A focus is identified in about 75% of cases which means that the focus is sometimes missed. This prospective single arm pilot study aims to assess a new automated lesion detection algorithm, MELD, designed to identify focal cortical dysplasias (the most common pathology associated with focal epilepsy in children) on otherwise 'normal' MRI scans. The investigators will assess whether MELD can be used to improve the targeting of abnormalities in children undergoing SEEG recording at Great Ormond Street Hospital
The Efficacy and Safety of Minocycline in the Treatment of Drug-resistant Epilepsy in NORSE Patients...
Epileptic Seizures Related to DrugsExploring the efficacy and safety of oral minocycline combined with antiepileptic drugs in the treatment of drug-resistant epilepsy in NORSE patients, obtaining preliminary research data, and providing evidence and data support for the next large-scale randomized controlled clinical study.
Mindfulness Meditation for Epilepsy
EpilepsyIn one-third of epileptic patients treated in France, seizures persist despite drug treatment. These so-called "refractory" epilepsies are among the most severe. Only a minority of patients with refractory epilepsy can undergo surgery. The other options available are based on brain or vagus nerve stimulation interventions which clinical effectiveness is still being studied. Alternative therapies are needed both to decrease the frequency of patients' seizures and to improve their quality of life. The practice of mindfulness meditation has recently been included in the recommendations of the International League Against Epilepsy in order to alleviate anxiety or depression comorbid symptoms. This study falls within this framework by targeting two aspects of the pathology.
Extension Study to Evaluate the Safety and Tolerability of NBI-921352 When Used With Anti-seizure...
Focal Onset SeizureFocal Onset EpilepsyThis Phase 2, prospective, interventional, active extension study was designed to evaluate the long-term safety and tolerability of NBI-921352 as adjunctive therapy in adult participants with focal onset seizures who completed 11 weeks of treatment in randomized, double-blind, placebo-controlled Study NBI-921352-FOS2021. Eligible participants may enroll directly following the completion of the Week 11 study visit of Study NBI-921352-FOS2021 or after a gap following completion of that study.

Childhood Absence EpilepsyJuvenile Absence EpilepsyThe purpose of the study is to investigate the long-term safety, tolerability and efficacy of brivaracetam in pediatric study participants with childhood absence epilepsy (CAE) or juvenile absence epilepsy (JAE).
Diffusion MRI Methods to Minimize Postoperative Deficits in Pediatric Epilepsy Surgery
Focal EpilepsyThis 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.
