Filter by: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.
Epilepsy is the most common chronic neurological disorder in the world, affecting more than 50 million people worldwide. Approximately 35% of patients with epilepsy are refractory to all available antiepileptic drugs. Drug-resistant epilepsies are often partial or focal. Patients with drug-resistant focal epilepsy suffer from an increased risk of death, primarily due to seizure-related fatalities, in comparison with the general population. The only therapeutic option for this form of epilepsy is the surgical removal of the region of the brain responsible for seizures, called the epileptogenic zone (EZ). This requires the precise localization of the EZ based on a comprehensive pre-surgical evaluation of patients. Today the gold standard for localizing the EZ and validating a non-invasive technique for localization of the EZ remains intracerebral stereo-EEG (stereo-electroencephalography or SEEG) recordings of spontaneous seizures. The implementation strategy of the intracerebral depth electrodes is guided by clinical and neuroimaging data, including anatomical Magnetic Resonance Imaging (MRI), Positron Emission Tomography (PET) with FDG (fluoro-Deoxy-Glucose) and MagnetoEncephaloGraphy (MEG). Although the contribution of each technique in the pre-surgical localization of the EZ has already been shown, no wide-scale study has examined the cumulative contribution of these three techniques.
The purpose of this study is to evaluate the effect of different intravenous doses (IV) of a new anti-epileptic drug (AED) called lacosamide on continuous EEG (electroencephalogram) rhythms (or brain rhythms) in subjects with focal seizures and the tolerability of those doses by patients. In addition, this study will assess the effect of IV lacosamide on EKG (electrocardiogram), a test which checks for problems with the electrical activity of the heart.
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 is an open-label, single centre, parallel group study to evaluate the safety and pharmacokinetics of single oral doses of retigabine XR formulation in healthy adult Japanese subjects. To compare the pharmacokinetic and safety profile, Caucasian subjects are also incorporated. This study is intended to facilitate inclusion of Japanese patients in the global phase III program for retigabine XR formulation.
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.
