Open-label Long-term Study of Adjunctive Brivaracetam in Pediatric Subjects With Epilepsy

This study will evaluate the safety and tolerability of brivaracetam in pediatric subjects with epilepsy.

Start: August 2011

Noninvasive Pre-surgical Evaluation of Patients With Focal Epilepsy and Establishment of a Normative Imaging Database

Objectives: The overall study objective is to compare the sensitivities and specificities of morphometric analysis techniques using structural MRI images based on pre- and postsurgical localization of epileptic foci in patients undergoing presurgical evaluation for medically refractory epilepsy. To carry out these analyses, we aim to establish an age-stratified normative imaging database using healthy volunteers. Additional objectives are to identify abnormal networks in these patients using resting state fMRI/EEG and MEG/EEG, and to use language and memory fMRI tasks to examine the effects of epileptogenic zones and surgery on cognitive function and the networks associated with these functions. Study population: 300 adults and children (age 8-65) with uncontrolled focal epilepsy, and 200 age-stratified healthy volunteers. Design: A retrospective and prospective natural history study. Research procedures for patients in this study include neuropsychological testing and 1-4 MRI sessions during presurgical evaluation and an additional 1-3 MRI sessions and neuropsychological testing approximately 12 months post-operatively. Research testing (such as research neuropsychological tests or MRI scanning sequences) will be done during a visit for clinical testing whenever possible, likely reducing the number of required visits. Patients will also have optional MEG and 7T structural imaging. Data will also be obtained from patients who have already undergone epilepsy surgery if they had procedures as outlined in the protocol and are willing to share the data. Healthy volunteers will receive a subset of the pre-operative procedures for patients, requiring at least 3 visits. In order to ensure adequate data acquisition, subjects may be re-scanned up to three times for the portions of the study in which they participated, possibly requiring additional visits. Outcome measures: The main outcomes will be establishment of normative values for morphometric analysis methods in age-stratified normal controls, and comparison of the sensitivity and specificity of these measures to pre- and postsurgical localization of the epileptogenic zone. Secondary outcome measures will include determination of the sensitivity and specificity of source localization using MEG/EEG and resting state fMRI/EEG, and to evaluate changes in activation during rest, as well as language and memory fMRI tasks in patients pre- and postsurgically, to examine the effects of epileptogenic zones and surgery on cognitive function and the networks underlying these functions.

Investigating Epilepsy: Screening and Evaluation

Background: Epilepsy affects about 1 percent of the U.S. population. Most people with epilepsy respond well to medicine, but some do not. Researchers want people who have diagnosed or suspected epilepsy to participate in ongoing studies. They want to learn more about clinical care for epilepsy. They want fellows and residents to learn more about the care of people with epilepsy. Objectives: To learn more about seizures and find ways to best treat people with drug-resistant epilepsy. Eligibility: Adults and children ages 8 years and older with diagnosed or suspected epilepsy Design: Participants will be screened with: Physical exam Medical history Questionnaires Participants will have many visits. They may be admitted to the hospital for several weeks. Their medication might be stopped or changed. Participants will have many tests: Blood and urine tests EEG: Wires attached to the head with paste record brain waves. This may be videotaped. Thinking and memory tests MRI: Participants lie on a table that slides in and out of a tube. They perform simple tasks in the tube. MEG: Participants lie on a table and place their head in a helmet to record brain waves. PET scan: Participants lie on a table that slides into a machine. A small amount of radioactive dye is injected into their arm with an IV. For the IV, a small tube is inserted into the arm with a needle. Participants will stay enrolled in this study if they join other epilepsy-related studies. They may be contacted at intervals for follow-up. Their participation will end if they have not been seen clinically for their epilepsy for 3 years.

Tumor Related 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.

Optimization of the Parameters of Vagal Nerve Stimulation

Vagal nerve stimulation (VNS) is one of the neuromodulation techniques that can be indicated in patients suffering from refractory epilepsies, especially when an open resection has failed or is not indicated. However to date it is not possible to predict which patients will respond and what are the best parameters of stimulation to be set (pulse width, frequency and intensity). It has been shown that responders to VNS have reduced interictal cortical synchronicity on scalp EEG based on phase lag index (PLI), a marker of functional connectivity (Fc) The aim of this study is to test the following hypothesis: setting the parameters of stimulation on the basis of the lowest values of Phase Lag Index (PLI) obtained on scalp EEG with different settings of parameters (as compared with a randomly chosen set of commonly used parameters) will increase the rate of responders to VNS.

Transcranial Direct Current Electrical Stimulation (tDCS) in Drug-resistant Epilepsy

This project aims to conduct a pilot study based on the targeting of the epileptogenic zone previously localized very precisely by stereoelectroencephalography (SEEG). SEEG is used as part of the pre-surgical assessment. It consists, thanks to the intracerebral implantation of electrodes in the brain of patients, to perform an intracerebral electrophysiological recording and thus to precisely explore the epileptogenic regions. In order to study the neuromodulatory and therapeutic effects of tDCS on epileptic brains, non-invasive techniques for measuring electrophysiological brain activity such as magnetoencephalography (MEG) and high-resolution electroencephalography (HR EEG) will be used. Finally, since epilepsy is considered to be a disorder of brain functional networks associated with disturbed brain connectivity, the effects of tDCS on cortical excitability by studying the variations in functional connectivity induced by stimulation will be studied.

RESting-state Functional MRI for Prediction of Post-surgical Prognosis In Pediatric Drug-Resistant Epilepsy

When patients arrive in the waiting room of the MRI department, patients and holders of parental authority will be given the information note explaining the objective of the study and its unfolding. During the consultation, the radiologist will check the inclusion and non-inclusion criteria, and will take the time to answer all of their questions about the study. If the patient and the holders of parental authority agree to participate in the research, the investigative doctor will obtain his consent. The MRI examination will be performed on a 3T multi-parametric MRI. Compared to the standard protocol, patients will benefit from an additional sequence of f-mRI, called resting state, and performed before injection of gadolinium contrast agent.

Investigation of Blood-Brain-Barrier Breakdown Using Manganese Magnetic Resonance Imaging in Drug-Resistant Epilepsy

Background: - The blood-brain barrier separates the brain from the rest of the body. Epilepsy is a neurological disease that causes seizures. It can affect this barrier. Researchers think a contrast agent called mangafodipir might be better able to show areas of the brain that epilepsy affects. Objective: - To see if mangafodipir is well tolerated and safe. To see if it can show, on an MRI, areas of the brain that epilepsy affects. Eligibility: People ages 18-60 who: Have epilepsy not controlled by drugs Prior or concurrent enrollment in 18-N-0066 is required Design: Participants will be screened with: Medical history Physical exam Blood and urine tests Participants will have up to 6 visits in 1-3 months. Those with epilepsy will have an inpatient stay lasting 2-10 days. Visits may include: Video-EEG monitoring for participants with epilepsy An IV catheter put in place: a needle guides a thin plastic tube into an arm vein. Getting mangafodipir through the IV. 5 MRI scans over a 10-day period: a magnetic field and radio waves take pictures of the brain. Participants lie on a table that slides into a metal cylinder. They are in the cylinder for 45-90 minutes, lying still for up to 10 minutes at a time. The scanner makes loud knocking sounds. Participants will get earplugs. A final MRI at least 2 weeks after receiving mangafodipir. Gadolinium is given through an IV catheter.
