Filter by:This study will evaluate the safety and effectiveness of oxcarbazepine (Trileptal) as add-on therapy in the treatment of partial seizures in pediatric patients 1 month to 3 years of age.
This study will use transcranial magnetic stimulation, or TMS (described below), to treat epilepsy in certain patients whose seizures persist despite optimum medical treatment. TMS used in this study is intended to lessen the number of seizures a patient has by decreasing excitability of the brain in the region where the seizures originate. Patients between 5 and 65 years of age who have had epilepsy for two or more years and have had at least one seizure a week for at least 6 months may be eligible for this 18-week study. Their seizures must come from a neocortical focus-that is, near the surface of the brain. Candidates will be selected from the NIH Epilepsy clinic and will be screened with an electroencephalogram (EEG), magnetic resonance imaging (MRI) scans, and blood tests. Participants will keep a diary of the seizures they experience over an 8-week period. After the 8 weeks, they will come to the NIH outpatient clinic for 6 consecutive days for the following procedures: - Day 1: A regular clinic visit, plus 6 hours of video-EEG recording (described below) - Days 2 through 5: Video-EEG monitoring and TMS as follows: 8:00 - 11: 00 a.m. 3 hours video-EEG monitoring 11:00 - 12:30 p.m. TMS (includes set-up time; actual stimulation time lasts 30 minutes) 12:30 - 3:00 p.m. Lunch + rest 3:00 - 4:30 p.m. TMS 4:30 - 7:30 p.m. 3 hours video-EEG monitoring (On the fifth day, subjects will have 6 hours of video-EEG monitoring in the afternoon instead of 3 hours.) Participants will be randomly assigned to one of two TMS groups. One group will have TMS delivered in a way that is thought to have a chance of reducing seizures; the other will have sham, or placebo, stimulation. When the TMS sessions are completed, participants will keep a diary of their seizures for another 8 weeks. Transcranial Magnetic Stimulation For TMS, an insulated wire coil is placed on the subject's scalp. A brief electrical current passes through the coil, creating a magnetic pulse that travels through the scalp and skull and causes small electrical currents in the cortex, or outer part of the brain. The stimulation may cause muscle, hand or arm twitching, or may cause twitches or temporary tingling in the forearm, head, or face muscles. During the stimulation, electrical activity of muscles is recorded with a computer or other recording device, using electrodes attached to the skin with tape. Some TMS sessions may be videotaped. Video-EEG Recordings The EEG recording device is housed in a small pouchlike container that is worn below the shoulder, attached to a belt worn around the waist.
The purpose of this trial is to work out design issues prior to conducting a definitive phase 3 trial to determine whether treating sleep-related breathing disorders in people with epilepsy results in improvement in seizure control or an improvement in alertness during the day.
This study will evaluate the long-term safety of LAMICTAL(lamotrigine)in subjects with partial seizures previously enrolled in protocol LAM20006 and in subjects 1-24 months of age who have never received LAMICTAL(LAMICTAL-naive). For LAMICTAL-naive subjects, LAMICTAL will be added to the subject's current epilepsy medications.
This study will measure and compare hormone levels in women with catamenial epilepsy (epilepsy in which seizures are more frequent during menstrual periods), women with seizures not related to their menstrual cycle, and normal control subjects. It will determine whether there are differences among the three groups in their hormone levels or in how fast the levels change. It will also examine what relationship, if any, exists between hormone changes and seizures in women with catamenial epilepsy. The hormones under study include the gonadal hormones estrone, estradiol and progesterone, and the neuroactive steroids allopregnanolone, pregnenolone, and dehydroepiandrosterone. Women who meet the following criteria may be eligible for this 3-month study: - Between 18 and 45 years of age, with catamenial epilepsy - Between 18 and 45 years of age, with seizures, but not catamenial epilepsy - Between 18 and 45 years of age, without seizures All participants will have a physical examination at the beginning of the study, at each clinic visit, and at completion or withdrawal from the study. In addition, they will undergo the following procedures: Baseline Monitoring For the first 2 months, all participants will keep a diary of their temperature and onset of menses. Women with epilepsy will also record their seizures. Electroencephalography (EEG) Healthy volunteers will have a 45-minute EEG (recording of the electrical activity of the brain) at the beginning of each menstrual cycle and each day during the menses. Women with epilepsy will have continuous EEG monitoring for 8 days, beginning 5 days before their menstrual period is expected. The continuous monitoring can be done on an outpatient basis, using a portable EEG recording device, or as an inpatient, with admission to the hospital for the 8 days of recording. Blood Sampling All participants will have a small blood sample (2 teaspoons) drawn once a day on days 10, 14, 17, 19 and 21 of their menstrual cycle and three times a day on day 6 and for a period of 8 days, starting 5 days before the expected menses and continuing for 3 days of the next cycle. For the days with three blood draws, a small needle that can stay in place for up to 72 hours will be placed in the arm to avoid the discomfort of multiple needle sticks.
This study includes patients 16 years of age or older with a confident diagnosis of epilepsy who are currently treated with an antiepileptic drug (AED) monotherapy but require a change in therapy due to inadequate seizure control and/or unacceptable side effects.
The purpose of this study is to evaluate the effectiveness and safety of an investigational new drug for supplemental therapy in subjects with primary generalized tonic-clonic (PGTC) seizures.
This study is being conducted to evaluate the effectiveness and safety of LAMICTAL added to the current therapy of pediatric patients age 1-24 months old with partial seizures. The medication used in this study has been approved by FDA for the adjunctive treatment of partial seizures in patients 2 years and older.
The purpose of our study is to identify gene(s) involved in the cause of childhood absence epilepsy (CAE).
The purpose of this trial is to compare the effectiveness of early surgical intervention for mesial temporal lobe epilepsy to continued treatment with antiepileptic drugs.
