Filter by:Unlike the first generation antiepileptic medications, newer drugs for epilepsy such as levetiracetam are reported to have less adverse effect in children but not many studies have systematically reviewed the subject. This study aims to prospectively evaluate the effect of levetiracetam on neurocognition, behavioral issues and quality of life, as well as its seizure control efficacy and other adverse events in pediatric epilepsy patients, in comparison to carbamazepine, one of the classic antiepileptic medication, widely prescribed for both partial and generalized seizures, despite its well known side effects. This multicenter, open-label, parallel-group trial is expected to enroll 130 patients from age 4 to 16 woh will be randomized into two groups, which will be prescribed with levetiracetam or carbamazepine. Series of neuropsychological assessment and behavioral and life evaluations of the patients will be performed at baseline period and after the 52 weeks of study period.
HEP is a five-year, prospective, observational study whose primary goal is to identify clinical characteristics and biomarkers predictive of disease outcome, progression, and treatment response in participants with newly treated focal epilepsy.
The main objective of the study is twofold: 1. Assess the clinical efficacy of DBS on epilepsy according to their number and severity at 1 year follow up. 2. Perform a cost-effectiveness analysis from the perspective of Medicare at 1 and 2 years. The study hypothesis is that thalamic DBS (neurostimulation of the anterior nucleus of the thalamus) will decrease significantly, the frequency (potentially 50% reduction in severe crises) of the most severe seizures, in at least 50% of patients who have drug-resistant partial epilepsy; and should also improve significantly the quality of life through a gain of independence in activities of daily life, the possible recovery of functional abilities, recovery of social or professional activities.
This is a multicenter, double-blind, randomized, placebo-controlled dose response study, with an 8-week prospective baseline and an 18 week double-blind treatment period (including a 6-week titration phase and 12 week maintenance phase), followed by a 3-week blinded study drug taper period (for subjects leaving the study) or a 2-week blinded conversion period (for subjects who will participate in the open-label extension). The primary objective of this study is to determine the effective dose range of YKP3089 as adjunctive therapy for the treatment of partial seizures. The trial will also evaluate the safety and tolerability of YKP3089 in the partial epilepsy population.
This study will evaluate a type of Magnetic Resonance Imaging (MRI) sequence called arterial spin labeling (ASL). The investigators hope that ASL can better localize areas of the brain (lesions) that cause epilepsy. This type of MRI does not require contrast, does not use any radiation, and adds on 4 minutes to the routine MRI that is done for patients with epilepsy. The study hypothesis is that in patients with refractory epilepsy, Arterial Spin Labeling (ASL) MRI will show areas of abnormality in the brain to the same degree as single-photon emission computerized tomography (SPECT) and positron emission tomography (PET) studies.
The purpose of this study is to determine weather Remegal in fixed dosage 1500 mg/daily is effictive and safe in patients with epilepsy with partial seizures
The investigators will treat patients with fully characterized refractory unifocal neocortical epilepsy with a technique that delivers magnetic waves (transcranial magnetic stimulation, TMS) to the region that causes the epilepsy. Active rTMS applied over the epileptogenic focus will reduce seizure frequency compared with sham rTMS.
To investigate whether MR-guided laser induced thermal therapy in patients diagnosed with focal lesional epilepsy using the Visualase Thermal Therapy System is both a feasible and safe minimally invasive technique for control of seizures in such patients.
This observational study aims to investigate how VIMPAT® is used as adjunctive therapy in clinical practice and will also evaluate the subsequent change in the drug load of patients after addition of VIMPAT® to their treatment regimen.
Background: - The brain is protected by a barrier that keeps toxins in the blood from reaching the brain. However, this barrier can also keep useful medications from reaching the brain. P-glycoprotein (P-gp) is a brain protein that is part of the blood-brain barrier. The level of P-gp is higher in people with epilepsy than in people without epilepsy. These different levels of P-gp may explain why some people have seizures that do not respond well to medications. Researchers want to see if P-gp can affect the response to epilepsy medications. - Epilepsy may also be associated with brain inflammation. Researchers also want to look at the part of the brain affected by epilepsy to see if inflammation is present. Objectives: - To see if P-gp can affect the response to epilepsy medications. - To see if inflammation is present in the part of the brain affected by epilepsy. Eligibility: - <TAB>Individuals between 18 and 60 years of age who have temporal lobe epilepsy. We plan to study some patients whose seizures are well controlled by drugs, and some whose seizures are not controlled. - <TAB> - Healthy volunteers between 18 and 60 years of age. Design: - This study requires four or five visits to the NIH Clinical Center over the course of a year. The visits will be outpatient visits and will last from 2 to 5 hours. - Participants will be screened with a physical exam and medical history. Blood and urine samples will be collected. - All participants will have two positron emission tomography (PET) scans. The scans will take place during different visits. Different drugs will be used in each scan. One drug will be used to temporarily block the effect of P-gp in the brain. The other drug will show areas of inflammation in the brain. - Participants with epilepsy will have a third PET scan. This scan will also look at P-gp activity in the brain. However, it will not use the drug that blocks the effect of P-gp. - All participants will also have one magnetic resonance imaging scan. This scan will help show brain function.
