Active clinical trials for "Epilepsy"

This study will investigate whether a Vagal Nerve Stimulator (VNS) causes measurable desynchronization and reduces epileptiform activity, such as spikes and seizures, in electrocorticograms (ECOGs) recorded by a Responsive Neurostimulator (RNS) in patients who have both devices implanted. Specific aims of the study: Evaluate the change in frequency of epileptiform discharges during active VNS stimulation compared to interstimulation baseline periods Evaluate the change in frequency of seizures during active VNS stimulation compared to interstimulation baseline periods Evaluate the change in the number of RNS activations during active VNS stimulation compared to interstimulation baseline periods Evaluate the change in synchronization of background ECoG (electrocorticogram) during VNS stimulation compared to interstimulation baseline periods.

The investigators propose a novel method for tracking the seizure frequency, side effect burden, and medication compliance for patients with epilepsy. The investigators intend to utilize a table-top device currently for tracking other chronic disease to collect remote data from epilepsy patients. The hypothesis is that the use of this device will lead to better longterm treatment outcomes than the standard outpatient mechanism of following patients longitudinally.

The purpose of this study is to determine if cannabidiol (CBD) obtained via the state of Minnesota reduces seizures in patients with severe intractable epilepsy (Dravet Syndrome or Lennox Gastaut Syndrome), and to measure blood levels of CBD to help determine CBD concentration-response characteristics.

Restricting dietary lysine intake in infants from age 3 months or less with confirmed diagnosis of pyridoxine-dependent epilepsy due to Antiquitin (ATQ) deficiency will: reduce the accumulation of neurotoxic substratesα-aminoadipicsemialdehydeandits cyclic equivalent 1-piperideine-6-carboxylate;and will improve overall neurodevelopmental outcome at 3 years of age by acting as an effective intervention into the complex pathophysiology of the condition.

Evaluate the contribution of multimodal high-resolution EEG-NIRS electrical and local haemodynamic analysis to spatial localization of epileptogenic foci

The purpose of the study is to evaluate a new technology for functional neuroimaging using electroencephalography (EEG) and MRI in studying epilepsy.

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.

This study will examine how certain language skills, such as naming objects, understanding spoken language and reading are organized in the brain and how they are affected by seizures. People with epilepsy who are considering surgery and healthy volunteers who are right-handed and between the ages of 7 and 55 may be eligible for this study. Participants undergo the following procedures twice, and, in some cases, possibly three times, in two or three visits of 2 to 4 hours each. Neuropsychological tests: Testing includes questionnaires, pen-and-pencil or computerized tests and motor tasks. Structural MRI: This procedure uses a strong magnetic field and radio waves to obtain pictures of brain structure. During the test, the subject lies in the scanner (a metal cylinder surrounded by a magnetic field) for about 90 minutes, wearing earmuffs to muffle knocking noises the machine makes. Subjects may be asked to lie still for up to 10 minutes at a time. Functional MRI: This procedure is similar to structural MRI, except a coil is placed over the head and the subject performs simple tasks during the procedure. The pictures obtained show what parts of the brain are being used to perform the task. The test lasts about 60 minutes, with subjects asked to lie still for up to 10 minutes at a time. Magnetoencephalography (MEG) and electroencephalography (EEG): For MEG, the subject sits in an MEG recording room with a cone containing magnetic field detectors lowered onto his or her head. Very small magnetic changes produced by the activity of the brain are recorded while the subject sits quietly or performs a research task. An EEG recording of the electrical activity of the brain is done at the same time as the MEG. ...

Follow-on study to continue evaluation of the safety of OXC XR as adjunctive therapy in pediatric epilepsy

People with epilepsy are at a higher risk for sudden unexpected death than the general population. Sudden unexpected death in epilepsy (SUDEP) is a major cause of death in this population, accounting for 10-50% of deaths for those with epilepsy. The risk for SUDEP is particularly high for those with refractory epilepsy. Several lines of evidence support a cardiac mechanism for SUDEP. This study plans to determine: the frequency and types of cardiac arrhythmias that occur in this population and whether these are increased above the general population in the same age group. Additionally, these data will be correlated to specific clinical data, including seizure history, anticonvulsant medications, and any accompanying clinical symptoms.
