Active clinical trials for "Epilepsy"

This study investigates how seizures can vary over time with changes in low grade gliomas and its treatments. This study may help doctors find symptoms or triggers of seizures earlier than normal, and ultimately earlier care or treatment for seizures.

The Congenital Muscle Disease Patient and Proxy Reported Outcome Study (CMDPROS) is a longitudinal 10 year study to identify and trend care parameters, adverse events in the congenital muscle diseases using the Congenital Muscle Disease International Registry (CMDIR) to acquire necessary data for adverse event calculations (intake survey and medical records curation). To support this study and become a participant, we ask that you register in the CMDIR. You can do this by visiting www.cmdir.org. There is no travel required. The registry includes affected individuals with congenital muscular dystrophy, congenital myopathy, and congenital myasthenic syndrome and registers through the late onset spectrum for these disease groups. The CMDIR was created to identify the global congenital muscle disease population for the purpose of raising awareness, standards of care, clinical trials and in the future a treatment or cure. Simply put, we will not be successful in finding a treatment or cure unless we know who the affected individuals are, what the diagnosis is and how the disease is affecting the individual. Registering in the CMDIR means that you will enter demographic information and complete an intake survey. We would then ask that you provide records regarding the diagnosis and treatment of CMD, including genetic testing, muscle biopsy, pulmonary function testing, sleep studies, clinic visit notes, and hospital discharge summaries. Study hypothesis: To use patient and proxy reported survey answers and medical reports to build a longitudinal care and outcomes database across the congenital muscle diseases. To generate congenital muscle disease subtype specific adverse event rates and correlate with key care parameters.

Genetic diagnosis for neonates suffering from epilepsy has important implications for treatment, prognosis, and development of precision medicine strategies. Investigator performed exome sequencing (ES) or targeted sequencing on neonates with seizure onset within the first month of life. Investigator subgrouped our patients based on the onset age of seizure into neonatal and before 1 year (1-12 months), to compare the clinical and genetic features and treatment strategies.

Electrical activity emerges in the third trimester of pregnancy, plays an important role in the construction of cortical maps, and is impaired in patients with severe early epileptic encephalopathies (EOEE). EOEE are rare and severe epileptic syndromes characterized by epilepsy that begins within the first three months of life and is associated with rapid deterioration of motor, cognitive and behavioral skills. There is a genetic basis for the EOEE. Together with other laboratories, the investigators have identified de novo pathogenic variants in the KCNQ2 gene encoding the Kv7.2 subunit of the Kv7 / M potassium channel, a channel known to control neuronal excitability in the brain and spinal cord. via the current M (IM). Pathogenic variants of the KCNQ2 gene represent the main cause of EOEE and the term KCNQ2-related epileptic encephalopathy (KCNQ2-REE) is now used to define this condition. KCNQ2-REE patients have a remarkably homogeneous phenotype at the start, with epilepsy that begins in the first days after birth, seizures that result in tonic muscle spasms that last from 1 to 10 seconds, and an interictal EEG called "suppression-burst". "That is, paroxysmal bursts of activity interspersed with periods of electrical silence. In this group, more than 50% of the patients present a remission of the epilepsy and a quasi-normalization of the EEG which can occur a few weeks to several months after the onset of the seizures. Despite this positive evolution in terms of seizures, the developmental progression is abnormal and the phenotype is severe with an absence of language, autistic behavior and a subsequent development of motor disorders such as diplegia, spasticity, ataxia or dystonia. The ambition of this project is to increase knowledge of epileptic encephalopathies linked to KCNQ2 at the clinical and molecular levels, to decipher the pathophysiological mechanisms and to propose therapeutic strategies. This project aims to better describe the clinical, EEG, imaging, developmental and long-term follow-up characteristics of patients carrying the KCNQ2 mutation identified in the laboratory.

Prospective controlled studies to identify clinical epilepsy control, cognitive changes, and safety in VNS treatment of tuberculosis-related epilepsy.

Prospective interventional study with implantation of micro-electrodes to study the brain networks in epilepsy at high spatiotemporal resolution.

The goal of this clinical trial is to learn if new educational program prior to epilepsy surgery can either decrease the risk of cognitive decline after surgery or be a help to those patients who experience a decline after undergoing epilepsy surgery. Participants will participate in 2 individual virtual sessions and 4 virtual group sessions over the course of 5-6 weeks prior to their epilepsy surgery. They will asked to fill out online surveys and questionnaires at various times throughout the study, up to 12 months after their surgery. To see if the educational program works, researchers will compare those participating in the educational program with those that are receiving the standard epilepsy care prior to surgery.

The role of human microbiota in neurological disorders via the "microbiota-gut-brain axis" is recently gaining increased attention due to the knowledge that gut microorganisms are involved in multiple gut and brain functions and metabolic pathways. The hypothesis of the present investigation is that changes of gut microbiota and their metabolic products may be a mechanism of the effectiveness of ketogenic diet in epilepsy. The aim of the present study is to investigate the changes of gut microbiota induced by the ketogenic diet and if certain populations of microorganisms are associated with better seizure control in epileptic children. This is a non-interventional study that will include epileptic children 2-18 years old eligible for ketogenic diet. The gut microbiome of participants will be examined in stools before and three months after the implementation of an olive oil- based ketogenic diet therapy. One of the participants' parents will also be included providing fecal sample for the examination of gut microbiome.

Overall, this study will investigate the functional utility of stereotyped HFOs by capturing them with a new implantable system (Brain Interchange - BIC of CorTec), which can sample neural data at higher rates >=1kHz and deliver targeted electrical stimulation to achieve seizure control. In contrast to current closed-loop systems (RNS), which wait for the seizure to start before delivering stimulation, the BIC system will monitor the spatial topography and rate of stereotyped HFOs and deliver targeted stimulation to these HFO generating areas to prevent seizures from occurring. If the outcomes of our research in an acute setting become successful, the investigators will execute a clinical trial and run the developed methods with the implantable BIC system in a chronic ambulatory setting.

This project focuses on anti-seizure medication (ASM) clearance and physiological factors determining blood concentrations in pregnant adult women with epilepsy and amounts of exposure to their unborn children and nursing infants.
