Filter by:Epilepsy is a common condition which affects over 3 million people in the US. Patients with uncontrolled epilepsy have a lifetime risk of sudden unexpected death (SUDEP) of 35%, which is greatest in those under 40 years of age. The exact mechanisms and causes are not understood but can be due to underlying conditions which affect the heart and brain, which may lead to dangerous heart rhythms and death. Some of these conditions which affect heart and brain have an identifiable genetic cause. This study aims to identify known genetic causes of heart rhythm and sudden death related disorders in patients with epilepsy.
The Pediatric Neurosurgery Service of the Rothschild Foundation (Paris) is the French leader center for surgery of epilepsy in infants and children. Postoperative follow-up of these children is performed during medical and neurosurgical consultations in order to assess the frequency of attacks and to reduce medication. On average, two postoperative consultations are carried out between 3 and 5 months and between 12 and 18 months. Beyond 18 months, some children may benefit from long-term monitoring at this center, but most children are followed by their neurologist . Therefore, the center has no rigorous and systematic collection of standardized data on the outcome of these patients. The purpose of this study is to evaluate the efficacy of the epilepsy surgery in children with a monitoring of 3 years.
The purpose of this study is to evaluate the feasibility, safety, and initial effectiveness of Exablate thermal ablation of a focal epileptic target area in the brain of patients suffering from medication-refractory epilepsy, using the Exablate transcranial system to produce multiple sonications targeted in the focus of interest. The investigators will establish the feasibility and collect data to establish the basic safety of this type of treatment as the basis for later studies that will evaluate its full clinical efficacy.
The goal of the present study is to obtain pilot data on efficacy and safety of clobazam add-on treatment on adults with drug-resistant focal epilepsy. This will be an open label study comparing seizure frequency during 12 weeks of baseline observation period with seizure frequency during 16 weeks of clobazam adjunctive treatment. 10 adults aged 18-65 with focal seizures that have failed to respond to ≥ 4 antiepileptic drugs (AEDs) +/- respective surgery will be enrolled. Following a baseline of 12 weeks patients will be started on clobazam, administered orally in b.i.d. schedule. In patients in whom seizure diaries have been kept prospectively prior to study screening visit, retrospective baseline will be accepted. Patients will be titrated up to either seizure freedom, to side effects or to 40 mg/day, whichever comes first. Titration rate will be not be forced. It is anticipated that the majority of subjects will have a 4 week-long titration period. After maximum dose is achieved, maintenance treatment will last for 12 weeks.
The purpose of the study is to investigate effect of immunotherapy in intractable cryptogenic epilepsy patients with autoimmune antibody.
The ketogenic diet is a non-pharmacological treatment prescribed especially for children and indicated in most specialized centers for patients with refractory epilepsy. The composition of the ketogenic diet is based on high-fat, low-carbohydrate, moderate protein content, and the production of ketone bodies is the probable mechanism involved in the control of seizures. The relationship between the treatment of the ketogenic diet and changes in oxidative characteristics, physical and lipid are not well established. Some studies show a significant increase in total cholesterol and triglycerides in children being treated with ketogenic diet, but other studies have shown that changes in lipid profile in the long term do not appear to be significant, beyond the influence of these changes on coronary heart disease are unknown. The studies performed in the last two decades have shown that besides the changes in the lipid profile, oxidative modification of lipoproteins are essential for the initiation and progression of atherosclerosis and physical properties of lipoproteins also appear to be involved in this process, suggesting that the particle size of lipoproteins, through the analysis of subfractions can provide more details of the cardiovascular risk. Thus, this projetct aims to compare the effects of the classical ketogenic diet with the ketogenic diet modified with lower content of saturated fatty acids and a higher content of monounsaturated and polyunsaturated, the oxidative changes of LDL, lipidomic profile, the concentration of antioxidants in production inflammatory cytokines and the subfractions of LDL and HDL in children and adolescents with refractory epilepsy, the clinical effect on controlling epilepsy.
Background: Some people with brain tumors have seizures related to the tumor. This is called tumor-related epilepsy. Usually brain tumors are treated by removing as much of the brain tumor as possible without causing problems. Researchers think this may improve the outcome for people with brain tumors. It may completely relieve or greatly reduce the number of seizures they have. Objectives: To evaluate people with brain tumors that are associated with seizures and to offer surgical treatment. Also, to study how surgery affects seizures. Eligibility: People age 8 and older who have a brain tumor with associated seizures. They must be willing to have brain surgery to treat their epilepsy. Design: Participants will be screened with a review of their medical records. Participants will have a medical history and physical exam. Participants will be admitted to the hospital at NIH. They will have Medical history Physical exam Neurological exam Tests of memory, attention, and thinking Questions about their symptoms and quality of life Blood drawn They may also have: MRI or CT scan. They will lie on a table that slides in and out of a machine that takes pictures. For part of the MRI, they will get a dye through an intravenous (IV) catheter. Video electroencephalography monitoring. Electrodes will be placed on the scalp. The participant s brain waves will be recorded while doing normal activities. Participants will be videotaped. Participants will keep a seizure diary before and after surgery. Participants will have surgery to remove their brain tumor and the brain area where their seizures start. They will stay in the hospital up to a week after surgery. Participants have for follow-up visits at NIH.
Prospective cohort study on the long-term effectiveness and safety of PINS vagus nerve stimulators for children and adolescent with refractory epilepsy.
Evaluate the long-term clinical effectiveness and safety of the PINS Deep Brain Stimulation to patients with refractory epilepsy.
Studies on the cognitive function have highlighted promising results concerning attention. In contrast, in the field of memory, the single cohort study that has been carried out, has not been randomised, with non comparable groups, the significant outcomes are therefore to be balanced. In this study, patients with focal and structural temporal lobe epilepsy will be randomised in 2 groups : the COMETE group where patients will attend a specific rehabilitation programme of memory and the control group where patients will benefit from a standard treatment.
