Filter by:To assess the magnitude and duration of reduction in RNS recorded Detections and Long Episodes following intranasal administration of Valtoco®. All participants will have been implanted and treated with an RNS system for clinical purposes and regularly upload Detection and Long Episode data on a regular basis as part of regular clinical treatment. Participants will come to the clinic and be administered a single dose of Valtoco® via nasal spray. RNS recorded Detections and Long Episodes before and after Valtoco® administration will be compared. This is a pilot study, so all outcomes are exploratory.
Protocol Summary Population - Target population is 10 adults (18 to 75 years of age) with a diagnosis of treatment-resistant epilepsy with at least 20 seizures per year, and whose seizure onset recorded from scalp EEG is localized to a brain region accessible by the subcutaneous EEG electrodes Number of sites - Three sites; King's College Hospital NHS Foundation Trust, University College London Hospital NHS Foundation Trust, St George's University Hospital NHS Foundation Trust Study design - This study is an observational, non-randomised, non-interventional study. It is not intended as a device trial. It is not intended to assess the device performance, rather the usefulness of bio-signals in seizure prediction and in detecting seizure-associated phenomena. There will be no change to usual care as a result of taking part. A subcutaneous EEG device will be implanted under local anaesthesia to record continuous EEG and a non-invasive wrist-worn sensor will be used to acquire non-EEG bio-signals (eg. heart activity and rate, movements, muscle activity, electrodermal activity, body temperature) Objectives - The association will be investigated between non-invasive measurable variables related to stress and sleep, semi-invasive subcutaneous EEG phenomena, and the occurrence of seizures. The predictive value of change in non-invasive variables semi-invasive subcutaneous EEG phenomena for the occurrence of seizures will be assessed. Study Duration - Up to one year for each patient. Participants may be approached during or after this study to participate in related studies. Funding - This study receives funding from the Epilepsy Foundation of America, Innovative Medicines Institute (IMI) and UNEEG medical A/S.
A Randomized, Single-Dose, Parallel-Group Study to Evaluate the Pharmacokinetic Profiles of Two Formulations of Pregabalin after Oral Administration in Healthy Volunteers under Fasting Conditions
Three different dose titration schedules are tested to find a way to reduce the titration period of lacosamide
Evaluate the initial safety and effectiveness of Microburst VNS stimulation in subjects with refractory epilepsy.
The primary efficacy objective of the study is to determine if adjunctive therapy of natalizumab 300 mg intravenous (IV) every 4 weeks reduces the frequency of seizures in adult participants with drug-resistant focal epilepsy. The secondary efficacy objective is to assess the effects of natalizumab versus placebo in drug-resistant focal epilepsy on additional measures of seizure frequency.
Study of the Efficacy of the Treatment of Sleep Apnea Syndrome by CPAP in Pharmacoresistant Epilepsy. The primary goal is to evaluate the efficacity after 3 months of obstructive sleep apnea syndrome treatment by CPAP on the epilepsy seizures frequency.
Altered mental status (AMS) is one of the most common reasons for inpatient neurology consultation. Non-convulsive status epilepticus (NCSE) is frequently on the differential diagnosis of the patient with AMS. NCSE becomes more refractory to treatment after one hour of seizure activity, making rapid identification and treatment of NCSE of great clinical importance. Currently, an electroencephalogram (EEG) technologist must be called in from home during non-workday hours in order to obtain a stat EEG. The investigators propose the time required for diagnosis of NCSE at Mayo Clinic can be significantly decreased with rapid placement of an EEG cap by the onsite neurology residents.
This is a non interventional prospective study. Centers will enroll adult participants with partial onset seizures with or without secondary generalisation for whom the clinician has decided to initiate eslicarbazepine acetate (ESL) as an adjunctive therapy or monotherapy prior to the decision to take part in this study. Participants to be enrolled into the study will receive ESL either as an adjunctive therapy to one baseline antiepileptic drug (AED) or to at least two baseline AEDs or as monotherapy. Participants will be seen at baseline and at a follow-up visit after approximately 6 months to assess retention, efficacy, tolerability, quality of life (optional), and cognitive performances (optional).
Reconstruction software allows visualization of cortical structure in 3 dimensions, showing on a single picture the position of all the electrodes. The EEG signal of each recording plot of the electrode is analyzed and compared with the underlying brain structure reconstructed by the software. It is therefore possible to visualize 1) ictogenic and epileptogenic areas using neurophysiological stereoelectroencephalography (SEEG) data and 2) adjacent functional cortical areas with functional imaging and SEEG. Software makes it possible to determine the links between these areas. This study aims to show that using these software is an asset in surgical decision and in the choice of surgical strategy. Each patient has presurgical evaluation (usual care), including morphologic and (if necessary) functional MRI, EEG and SEEG. In this study, software will be used to analyze the processed data (FSL software, FMRIB laboratory, Oxford University and BrainVisa/Anatomist. The surgical decision will be taken according to the usual staff procedures, based on the usual examination results. After the decision making process, the staff will be asked to reconsider the surgical decision, according to the analysis provided by the software. The discrepancies between the decisions will be recorded.
