NCT07396883
This study focuses on children with Developmental and Epileptic Encephalopathy (DEE), a severe form of epilepsy that often has a genetic origin. Currently, standard diagnostic tools-known as short-read genome sequencing-fail to provide a diagnosis for over 50% of affected patients because they cannot detect certain complex DNA abnormalities. The purpose of this study is to evaluate the effectiveness of a newer, more advanced technology called Long-read Genome Sequencing (lrWGS). Unlike traditional methods, this technology analyzes very long fragments of DNA, allowing researchers to identify genetic errors that were previously "invisible." The study aims to answer whether Long-read Sequencing can successfully identify the genetic cause of epilepsy in patients who have already received a negative result from standard testing. By finding these missing answers, the research seeks to enable personalized medical treatments, improve genetic counseling for families, and advance our understanding of how these complex neurological conditions develop.
NCT06271785
This study investigates the usefulness of high resolution electrical source imaging (HR-ESI) in the setting of presurgical evaluation of drug-resistant focal epilepsy in children. This method is based on an estimation of the intra-cerebral source that produces a signal recorded by scalp electrodes by solving the inverse problem, taking into account attenuation factors resulting from particular conductivity properties of the cerebral, peri-cerebral and cranial tissues. Electrical sources are then fused on structural magnetic resonance imaging (MRI). Scalp EEG recorded using 64 to 256 electrodes refers to as high resolution EEG (HR-EEG), leading to HR-ESI. Studies based on small population of children or on mixt population of children and adults showed that HR-ESI has accuracy values, i.e. percentage of true positives (electrical source localized in the brain area resected and success of surgery) and true negatives (electrical source localized outside the brain area resected and failure of surgery) among the total population, ranging from 50 to 80%. Discrepancies between studies could be explained by the limited number of patients included or by the mixture of pediatric and adult data. Another limitation of previously published studies is that the spatial pattern of dipole source distribution was not taken into account to determine prediction accuracy of ESI. Studies using magnetoencephalography (MEG) to perform magnetic source imaging (MSI) suggest that the spatial pattern of dipole source distribution needs to be considered, a spatially-restricted dipole distribution being associated with better post-surgical outcome when resected. To tackle these issues, the investigators aim to conduct the first large prospective multicentric study in children with focal epilepsy candidates to surgery to assess prediction accuracy of ESI based on the finding of tight clusters of dipoles. This is original as this pattern (tight versus loose cluster of dipoles) has been studied by several researchers using MEG but not using HR-EEG. The investigators make the hypothesis that HR-EEG will allow to identity good candidates for epilepsy surgery and thus to offer this underutilized treatment in more children with better post-surgical outcome. Among the secondary objectives, the investigators will address methodological issues related to the resolution of the inverse problem (methods using distributed sources models versus methods based on equivalent dipole estimation), the potential added value to model high-frequency oscillations (HFO), and the investigators will assess the cost-utility of the HR-ESI procedure.
NCT05439876
The purpose of this study is to evaluate the effect of melatonin for improving sleep in pediatric epilepsy.
NCT06300814
This study was planned as a randomized controlled experimental study with a pretest-posttest design to determine the effect of parental supervision and video-guided progressive relaxation exercise (PRE) and music recital on sleep, quality of life and emotional states in children with epilepsy aged 9-16 years. The main questions it aims to answer are as follows: According to the evaluation of children with epilepsy, does the progressive relaxation exercise applied to children have an effect on sleep, quality of life and emotional states? According to the evaluation of children with epilepsy, does music recital applied to children have an effect on sleep quality of life and emotional states? The study consisted of 45 children (15 children in the progressive relaxation exercise group, 15 children in the music recital group and 15 children in the control group). Ethics committee approval, permission from the institutions and informed consent of the children were obtained for the conduct of the study. A value of p\<0.05 was considered statistically significant in data analysis.
NCT06967727
The Registry and Natural History of Epilepsy-Dyskinesia Syndromes is focused on gathering longitudinal clinical data as well as biological samples (blood, urine, and/or skin/tissue) from male and female patients, of all ages, who have a genetic diagnosis of epilepsy-dyskinesia syndromes. Through prospective review and molecular data analysis, the study aims to identify patterns and correlations between movement and seizure disorders, uncovering genotype-phenotype relationships. The initiative's goals are to enhance understanding of epilepsy-dyskinesia syndromes, inform precision medicine approaches, and foster international collaboration.
NCT06602570
Overall, this observational cohort study aims to: 1. Improve our understanding of the genetic architecture of childhood focal epilepsies. 2. Develop a liquid biopsy of cerebrospinal fluid (CSF) and assess feasibility to detect cerebral mosaicism using cell-free DNA (cfDNA) analysis and evaluate its performance against brain tissue on the panel testing. 3. Develop a methodology to use trace tissue from Stereoelectroencephalography (SEEG) DNA and assess feasibility to detect cerebral mosaicism and evaluate its performance against brain tissue on the panel testing. 3\. Validate the use of the liquid biopsy and SEEG trace tissue for use in the English National Health Service clinical services and share with other Genomic Laboratory Hubs.
NCT04639310
To investigate the potential antiseizure effects of adjunctive XEN496 (ezogabine) compared with placebo in children with KCNQ2 Developmental and Epileptic Encephalopathy (KCNQ2-DEE).
NCT06444126
The goal of this observational study is to learn about the recurrence and development of epilepsy in children hospitalized with their first febrile seizures. The main questions it aims to answer are: * What is the risk of recurrence after the first febrile seizure and what are the risk factors for recurrent febrile seizures in Vietnamese children? * What is the risk of developing epilepsy later in life and what are the risk factors for developing epilepsy in Vietnamese children who have had febrile seizures?
NCT06400966
The aim of this study is to examine the effect of the education given to nursing students with the Jigsaw technique and traditional method on their knowledge and attitudes about childhood epileptic seizure management.
NCT06310954
This study aims to evaluate the efficacy of a ketogenic diet in treating pediatric intractable epilepsy and to explore its relationship with changes in inflammatory markers. The investigators plan to recruit 59 participants with intractable epilepsy, 39 of whom will receive a combination of ketogenic diet and conventional antiepileptic drugs, while 20 will receive only conventional drugs. The study will assess the impact of the ketogenic diet on epilepsy control and inflammatory markers, hoping to discover new treatment strategies.
NCT04545346
The study is investigating if following the low glutamate diet for 1 month, as compared to care as usual, can improve seizure frequency, severity, and duration; cognitive functioning; and/or quality of life in children with epilepsy.
NCT03909984
This is a multicenter home-based medical device intervention study, with prospective validation of the wearable seizure detection device (Nightwatch) and retrospective validation of remote sensors (video and audio detection) in children. The investigators will also perform a feasibility and utility analysis of Nightwatch.
