NCT01281956
Background: \- The brain chemical serotonin helps nerve cells communicate. Previous research suggests that serotonin activity may be lower in brain areas where seizures start, and that increasing activity at the serotonin receptor site on nerve cells may help prevent seizures. Researchers are interested in determining whether the experimental medication PRX-00023, which increases the activity of serotonin receptors, can reduce seizure frequency in people whose seizures are not well-controlled on antiseizure medication. PRX-00023 has not previously been studied in people with epilepsy and has not previously been given to people taking antiseizure medication at the same time. Objectives: \- To evaluate the effectiveness of PRX-00023 in reducing the frequency of epileptic seizures that start from only one part of the brain. Eligibility: \- Individuals between 18 and 65 years of age who have frequent epileptic seizures even after trying at least two different standard anti-seizure medications (either at the same time or one after the other). Design: * The study requires 9 outpatient visits to the NIH Clinical Center over a 34-week period. Individuals who choose to participate in additional studies may be an inpatient during some of these visits. * Participants will be screened with a medical history and physical examination, blood and urine samples, ECG, EEG, neuropsychological studies, imaging studies, including PET and MRI scans * Participants will have a 6-week observation and evaluation period before starting the study medication. Participants who have at least four seizures during this period will be eligible for the treatment portion of the study. * All participants will receive either PRX-00023 or a placebo pill twice daily for 12 weeks, and will have regular clinic visits with blood samples and imaging studies. * After the 12-week period, participants will have a 2- to 3-week washout period without any study medication. * Participants will then have another study medication period, and will receive the opposite pill (PRX-00023 or placebo) from the one taken in the first treatment phase. Participants will continue to have regular clinic visits with blood samples, ECG, EEG and neuropsychologicalstudies. * One month after the end of the second study medication phase, participants will have a followup evaluation with a physical examination, blood tests, ECG, EEG, mood and neuropsychological tests. Outcome measures: The primary outcome measure for drug efficacy will be: Mean difference in seizure frequency comparing the active and placebo periods. Secondary outcome measures for efficacy will be: Proportion of patients with greater than or equal to 50% lower seizure rate on PRX-00023 than placebo Hamilton Depression and Anxiety Rating scales Performance on mood and neuropsychological testing scales
NCT00310388
This Phase 3 trial is an open-label extension study of the placebo-controlled, double-blind VRX-RET-E22-302 trial. Patients who have completed the VRX-RET-E22-302 trial and who meet inclusion and exclusion criteria will be treated with 600-1200 mg/day of retigabine as an adjunct therapy to their current antiepileptic drugs (AEDs) or vagal nerve stimulation. Treatment will be continued until the subject withdraws from the study or until the program is discontinued. Patients will be recruited from 55-60 sites in Europe, Israel, Australia, and South Africa. The primary objective of the study is to evaluate the safety and tolerability of long-term therapy with retigabine administered as adjunctive therapy in adult epilepsy patients with partial-onset seizures, who completed the double-blind Study VRX-RET-E22-302. Secondary objectives are: to evaluate efficacy of long-term treatment with retigabine and patient quality of life and to evaluate whether retinal pigmentation, unexplained vision loss, pigmentation of non-retinal ocular tissue, and discoloration of nails, lips, skin or mucosa change over time after discontinuation of retigabine.
NCT02447198
Legislation to allow medical marijuana has had a significant impact on the pediatric population of Colorado. There have been many reported different effects and properties of each of the over 60 known cannabinoids found in marijuana. The main exposures in pediatrics have involved the use of Cannabidiol (CBD) high- and Tetrahydrocannibinol (THC) low-content hash oil in children with epilepsy. The reported benefit of this oil is to have the anticonvulsant properties of CBD without the psychoactive components of THC. Human studies on the efficacy of CBD on epilepsy are few and limited. The investigators' specific aims are the following: * Specific Aim 1: Describe the plasma pharmacokinetics of Cannabidiol (CBD), Tetrahydrocannibinol (THC), and their respective metabolites in pediatric patients with epilepsy. * Specific Aim 2: Describe the plasma pharmacokinetics of other antiepileptic drugs (AEDs) taken in conjunction with CBD in order to evaluate drug interactions. * Specific Aim 3: Describe parental perception of efficacy of CBD on control of epilepsy. The investigators will recruit children and their parents who are currently using or plan to use CBD for their seizure disorder. This study will NOT be providing patients with CBD. Consenting subjects will undergo a number of blood and urine collection that will be analyzed to describe the pharmacokinetics and possible drug interactions of CBD in pediatric epilepsy.
NCT00612235
This study is being done to determine if there are differences in mood during the menstrual cycle among women with epilepsy who take various different antiepileptic drugs and women without epilepsy.
NCT02484001
This is a Phase III, multinational, open-label, non-controlled study with subjects under treatment in the double-blind BIA-2093-311 study (NCT01162460). Subjects will enter the open-label extension study after the preceding double-blind study was unblinded and they are attending their last Extension Phase Visit (EPV) of the double-blind study. For all subjects, the day of the last EPV of the double-blind study will also be the day of Visit 1 for the open-label extension study. All subjects will receive Eslicarbazepine acetate (ESL) under open-label conditions at Visit 1. The complete study duration including treatment with ESL under open-label conditions and follow-up is expected to last approximately 2 years (105 weeks). In case ESL as monotherapy will achieve MA prior to the end of 2017, the study may be discontinued prematurely within 42 days after achievement of MA.
NCT00175825
This trial will evaluate the efficacy and safety of brivaracetam (at doses of 5, 20 and 50 mg/day in twice a day administration) as add-on therapy in subjects with focal epilepsy.
NCT02589470
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.
NCT02898935
Reconstruction software allows visualization of cortical structure in 3 dimensions, showing on a single picture the position of all the electrodes. The EEG signal of each recording plot of the electrode is analyzed and compared with the underlying brain structure reconstructed by the software. It is therefore possible to visualize 1) ictogenic and epileptogenic areas using neurophysiological stereoelectroencephalography (SEEG) data and 2) adjacent functional cortical areas with functional imaging and SEEG. Software makes it possible to determine the links between these areas. This study aims to show that using these software is an asset in surgical decision and in the choice of surgical strategy. Each patient has presurgical evaluation (usual care), including morphologic and (if necessary) functional MRI, EEG and SEEG. In this study, software will be used to analyze the processed data (FSL software, FMRIB laboratory, Oxford University and BrainVisa/Anatomist. The surgical decision will be taken according to the usual staff procedures, based on the usual examination results. After the decision making process, the staff will be asked to reconsider the surgical decision, according to the analysis provided by the software. The discrepancies between the decisions will be recorded.
NCT02451618
For any newborn that exhibits possible seizure activity or has altered mental status of unknown etiology, continuous bedside EEG recording is the standard of care to detect subclinical seizure activity. The experimental aspect of this study will be the application of test electrodes (EES or EKG) to evaluate if the electrodes can be used to produce a continuous bedside recording of brain activity in the same manner as an EEG recording, while ideally producing less irritation of newborn skin than conventional EEG electrodes.

NCT00903786
The purpose of this trial is to investigate the safety and tolerability of perampanel in long- term treatment in the patients with refractory partial epilepsy (uncontrolled with other anti-epileptic drugs) who completed Week 10 of Phase II Study E2007-J081-231 study.
NCT00194870
Patients with epilepsy undergoing deep brain stimulation (DBS) have electroencephalograms (EEGs) recorded before and during their stimulation treatment. Subsequently the investigators will be using computer-assisted analysis of the digitally-recorded EEG signals to assess the effects of DBS on the brain-wave frequency content and any abnormal seizure-like patterns that may be present.
NCT02899832
This study will included 20 children presenting with epilepsy with spasms. It aims to offer these children, non invasively and without supplementary examinations, a recording of local and cerebral hemodynamic changes concomitant with an electroencephalographic recording during epileptic episodes. This will be carried out by combining optical imaging using near infra-red spectroscopy (NIRS) with electroencephalography (EEG), in a simultaneous high-resolution (HR) recording. This study is among those based on multimodal analyses of epilepsy, combining methods of analysis of electrical activity (electrical imaging) and hemodynamics (optical imaging). Surface electroencephalography (EEG) is a precious tool enabling the study of neuronal dysfunction from a functional point view. It is used in the routine follow-up of children with epilepsy. Optical imaging is a promising medical imaging technique. It uses light in the spectral regions of near infra-red as a source of radiation. It is quantitative, rapid, non invasive, and inoffensive which could easily be used at the child's bedside or in a clinical setting and can provide metabolic information about cerebral function. This study is multidisciplinary, which calls upon the skills of neurophysiologists, biophysicists, and clinicians
NCT02344706
A large proportion of patients (up to 20%) who suffer from an epileptic seizure and remain unconscious suffer from a non-convulsive epileptic seizure. The condition is difficult to diagnose, and impossible without the required instruments. Electroencephalogram is required in the diagnosis of non-convulsive status epilepticus. Presently, the diagnostic value and implementation of such a device in the prehospital field is little studied. The aim of this study is to evaluate the diagnostic value of the acquired electroencephalogram with a prototype EEG/EKG adapter connected to a Physio-Control LifePak 15 defibrillator/monitor. The EEG is registered in a otherwise normal fashion with scalp-electrodes, but only three channels are monitored, as this is deemed sufficient for the prehospital field, as well as for monitoring the epileptic seizures.
NCT03338478
Patients with epilepsy exercise less than the general population. A barrier to exercise may be the effect of antiepileptic drugs on balance and reaction time. This proposal endeavors to study the effect of two common antiepileptic drugs (levetiracetam and lamotrigine) on balance and reaction time using a Wii balance board and reaction time test. This will be tested at descending doses in an epilepsy monitoring unit. Drug levels will be monitored, as well as center of pressure, and reaction time.
NCT02814331
