Active clinical trials for "Epilepsy"

To evaluate, over 1 year period, the efficacy and safety of newly prescribed levetiracetam as add-on treatment (POS, myoclonoc seizures in JME and PGTCS in IGE) or primary monotherapy (partial onset seizures) in adult and paediatric patients within the approved age limits in routine clinical practice in Czech and Slovak Republics, Hungary, and Romania. Non-interventional study.

The purpose of this study is to collect data from patients who are diagnosed with epilepsy and are followed up in epilepsy clinics.

Clinical study with Lyrica (pregabalin) in patients suffering from epilepsy. This drug is used as adjunctive therapy with one or more antiepileptics. Lyrica has potential to reduce seizure frequency.

Objective: To study the relative balance of GABA (A) binding potential and glutamate utilization in subjects with localization-related epilepsy with and without depression, subjects with major depressive disorder alone, and in subjects with generalized epilepsy (expected not to have significant comorbid depression). Pilot data shows that GABA(A) binding potential and glutamate utilization are tightly coupled in healthy subjects particularly in the mesial temporal lobe. We hypothesize that subjects with epilepsy will not exhibit the same degree of coupling, and that subjects with both epilepsy and depression will exhibit an even more pronounced decoupling. Study Population: Subjects aged 18-55 with localization-related epilepsy with and without depression, subjects with generalized epilepsy, subjects with major depressive disorder (MDD) alone, and healthy controls. Design: This is a neuroimaging study, using positron emission tomography (PET) with [11C]flumazenil, to measure GABA(A) binding potential, and [18F]fluorodeoxyglucose, to measure glucose utilization (reflective of neuronal glutamate release) Magnetic resonance spectroscopy (MRS), will be used to measure GABA and glutamate in the mesial temporal cortex, and corroborate the PET results. Structural magnetic resonance images (MRI) will be obtained for MRS localization and partial volume correction of PET images. Outcome measures: The binding potential of GABA(A), the regional rate of glucose metabolism, and the levels of GABA and glutamate as measured by MRS. Patients will be stratified by seizure type and depression ratings. ...

This is a multicenter, non-interventional, prospective study. The observation period comprises at least 6 months, from the initiation of ESL add-on therapy in adult patients with partial-onset epilepsy not sufficiently controlled with one AED, until the first visit that occurs between 6 and 9 months of follow-up. The observation period will end after 9 months of follow-up even if the final assessment is not performed.

The purpose of this clinical research study is to assess the bioavailability and pharmacokinetics of two formulations of diazepam after intranasal (nasal spray) and injectable diazepam after intravenous (I.V.) administration

Validation of qolie-10, an epilepsy specific quality of life questionnaire in patients treated with lamotrigine or valproic acid. Comparison of quality of life of epileptic patients treated with lamotrigine or valproic acid. Determination and assessment of the comparative safety of lamotrigine or valproic acid. Assessment and comparison of body image perception in women treated with lamotrigine or valproic acid.

The purpose of this observational study is to evaluate the safety of topiramate when used in combination with other medications for seizures in adults and children.

This study is designed to test the effects of vigabatrin (gamma-vinyl-GABA) an experimental drug used for the treatment of epilepsy. The study will use positron emission tomography (PET scan) to detect areas of the brain receiving increased blood flow and using increased amounts of glucose. Increases in blood flow and glucose use are good indicators of brain activity. Researchers are interested in determining the effects of Vigabatrin on brain blood flow and glucose use.

Ictal SPECT with intravenous injection in a cubital vein of a perfusion tracer is an established technique to localize the ictal onset zone during presurgical evaluation of refractory focal epilepsy. When seizures last less than 10 seconds, localizing information is often not obtained. Since it takes around 30 seconds before the tracer reaches the brain after intravenous injection, ictal hyperperfusion most likely has already switched to postictal hypoperfusion. In this study, we plan to inject the perfusion tracer in the aorta proximal to the cerebral arteries, which will allow a true ictal injection in patients with seizures of short duration.
