Active clinical trials for "Epilepsy"

The purpose of this study is to test a computer program for people with epilepsy. The program was developed to help people with epilepsy improve their self-management skills for taking medications, reducing stress, and sleeping well.

OBJECTIVES: About 15% of patients suffering from focal epilepsy are refractory to available pharmacological treatments. Until now, the only hope for such patients has been the development of new pharmaceutical treatments or epilepsy surgery. In case of inoperability, different types of invasive brain stimulation such as vagus nerve stimulation or deep brain stimulation or non-invasive repetitive TMS have been evaluated to determine their anticonvulsive potential. For rTMS, weak and short lasting seizure reduction has been reported in different epilepsy syndromes. A new, non-invasive stimulation technique, transcranial direct current stimulation (tDCS), was useful to modulate cortical excitability in many cortical areas (M1, visual cortex, frontal cortex). Cathodal tDCS, with a current of 1 mA, induced long-term depression in animal models and reportedly decreased the excitability of both human and animal cerebral cortex. In epilepsy patients suffering from a malformation of cortical development, a single session of cathodal tDCS helped reduce seizures briefly. The purpose of this protocol is to study the effects of repeated applications of tDCS on the excitability of the seizure focus in patients with poorly controlled pharmacologically refractory temporal lobe epilepsy. STUDY POPULATION: We plan to study 56 patients between the ages of 18 and 80 suffering from temporal lobe epilepsy. DESIGN: Subjects will be allocated by blocked randomization to one of two groups (parallel design). Group A will receive cathodal tDCS and group B will receive Sham-tDCS on five consecutive days. Each subject will participate in 9 sessions (1 baseline visit, 5 intervention visits, 3 follow-up visits). The effect of the intervention relative to the sham stimulation will be evaluated by comparing seizure frequency and neuropsychological tests during the 8 weeks before and after the intervention. OUTCOME MEASURES: Primary outcome measure will be the mean seizure frequency per 4 weeks in the tDCS group as compared to the Sham-tDCS group. To analyze the effect of the intervention (tDCS), seizures will be evaluated during a 2x4 week baseline period before tDCS and 2x4 weeks after the intervention. Using these data we will calculate the percentage change of seizures per 4 weeks. Secondary outcome measures will be the scores of the neuropsychological testing (HVLT-R, BVMT-R, CTMT, COWAT) and number of epileptiform discharges in the EEG. Furthermore, th...

Some antiseizure medication levels are affected by hormones. This study is being done to determine if blood levels of lamotrigine or valproate are affected by the hormones in the birth control pill or the menstrual cycle itself.

This study will examine the possible structural and functional abnormalities in patients with an inherited form of epilepsy. It will use magnetic resonance imaging (MRI). Uncontrolled epilepsy is a serious neurological problem with major harmful medical, social, and psychological effects, as well as greater mortality compared with the general population. The cost per year in the United States is at least $12.5 billion. There have been advances in diagnosing the disease, but the cause cannot be determined in many cases. Recently, several seizure syndromes found in families have been described. One syndrome of particular interest involves the lateral temporal lobe of the brain and often includes auditory features. Patients with that kind of syndrome may hear monotonous unformed sounds, but sometimes they may hear complex sounds, such as a song. Patients are eligible for this study if they have a specific form of familial epilepsy that is being studied at Columbia University in New York. Family members without seizures are eligible as well. All the patients in the study will be evaluated at Columbia before participating. Healthy volunteers aged 18 to 55 also may be eligible for this study. Participants will undergo a medical history and physical examination. During the study, they may have three or four sessions of MRI. During the MRI, patients will lie still on a table that can slide in and out of a metal cylinder surrounded by a strong magnetic field. Scanning time varies from 20 minutes to 3 hours, with most scans lasting between 45 and 90 minutes. Patients may be asked to lie still for up to 60 minutes at a time. As the scanner takes pictures, there will be loud knocking noises, and the patients will wear earplugs to muffle the sound. Patients will be able to communicate with the MRI staff at all times during the scan and may ask to be moved out of the machine at any time. Some scans may be done in a 3 Tesla scanner. It is the latest advance in MRI, with a stronger magnetic field than in the more common 1.5 Tesla scanner. Functional MRI (fMRI) is done while patients are performing tasks, such as moving a limb or speaking. Patients will have an opportunity to practice such tasks before entering the scanner. The fMRI will take about 1 hour. ...

Transcranial Magnetic Stimulation (TMS) is a non-invasive technique that can be used to stimulate brain activity and gather information about brain function. It is very useful when studying the areas of the brain related to motor activity (motor cortex, corticospinal tract, and corpus callosum). Epilepsy is a condition associated with seizures as a result of an over excitable cerebral cortex. Despite the introduction of several new antiepileptic medications, less than half of the patients diagnosed with partial epilepsy are well controlled. However, studies have shown that non-invasive stimulation of the brain can decrease the excitability of the cerebral cortex. Researchers are interested in the potential therapeutic effects of TMS on patients with epilepsy that have responded poorly to standard medication. This study will use TMS to decrease the excitability of the areas of the brain responsible for seizures.

We have discovered a small change in the genetic code which increases the risk of the brainwave abnormality that is found in rolandic epilepsy. We now wish to confirm this using a second much larger sample of patients. We will investigate the other genetic changes that cause people with the brainwave abnormality to develop seizures, as well as problems with speech, coordination, attention and learning.

The purpose of the study is to assess the feasibility of a Creative Artists Program intervention with epilepsy and headache patients admitted to Dartmouth-Hitchcock Medical Center for care by the Department of Neurology.

The purpose of this study is to assess the safety of perampanel in the treatment of partial onset seizures in participants of age 12 years and older with epilepsy.

The purpose of the dMRI-1 data collection study is to establish a database of clinical images and limited medical history information from patients that have previously received a dMRI scan. All data collected will be de-identified. No safety or effectiveness assessments will be completed.

Dravet syndrome is a severe infantile onset epilepsy syndrome with a prevalence of 1/15.000 to 1/30.000. An infant with an apparently normal development presents around 6 months of age with a convulsive status epilepticus. Seizures can be triggered by fever, illness or vaccination. Because of its drug-resistance, in the past, most attention has been paid to seizure control. However, developmental and behavioural problems also become a serious concern during the second year of life. Outcome is poor, with intellectual disability and ongoing seizures. On the long term, the deterioration in gait is very characteristic. A crouch gait pattern develops that largely impacts the daily life functioning. Most children maintain the ability to walk around the house, but for longer distances they must rely on wheelchair use, which further negatively affects their mobility. Gait analysis, when combined with physical examination, provides quantitative information to guide treatment of gait disorders and assess its outcome. The goal of this project is the development of a clinical decision framework based upon 3D gait analysis to diagnose and treat mobility problems in children with Dravet syndrome. Two major university hospitals in Flanders (UZA and UZ Leuven) are partners in this project. The parent organisation "Stichting Dravetsyndroom Nederland/Vlaanderen" will also participate, as intermediate partner to facilitate contacts between all parties being patients and their caregivers, clinical gait labs and treating physicians.
