Filter by: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).
The purpose of this pilot study is to describe the relationship of regional cerebral oximetry and cytoximetry, measured using near-infrared spectroscopy, with seizure activity in the periictal period in children with epilepsy.
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.
Brain somatic mutations in genes belonging to the mTOR signaling pathway are a frequent cause of cortical malformations, including focal cortical dysplasia or hemimegalencephaly. The present study aims to search for brain somatic mutations in paired blood-brain samples and perform functional validation in children with drug-resistant focal epilepsy
The knowledge of encephalitis associated with antibodies targeting intracellular antigens, and neuronal surface antibody syndromes has expanded considerably in recent times. The primary purpose of the investigators protocole is to determine the incidence of anti-neuronal antibodies (blood and CSF) in a population of patients suffering from focal epilepsy of unknown cause to guide the management of these patients. The investigators hypothesis is that dysimmune encephalitis is more common than is suggested by the current literature, and that sometimes forms of encephalitis dysimmune "at minimum" can be observed only in the form of focal epilepsy without further manifestation associated.
This is a single site, non-randomized, prospective, open-label, interventional pilot/feasibility study. Patients recruited will have medically-refractory focal neocortical epilepsy, defined on the basis of presence of focal spikes and (if available) focal seizure onsets originating from the lateral cortical surface of any lobe. All patients and referring physicians will be requested to maintain their current antiepileptic drugs throughout the study with changes after enrollment permitted only to maintain pre-enrollment drug levels, or if clinically necessary. The primary outcome measure will be the change in seizure frequency (seizures/week) as compared to baseline. Patients with medically-refractory neocortical epilepsy will receive cathodal tDCS administered to the seizure focus for 10 sessions over a 2-week period with the allowance of make-up sessions in week three. Subjects will be evaluated at baseline, during the stimulation sessions, and 8 weeks after the completion of the tDCS visits
The purpose of this study is to evaluate the feasibility, safety, and initial effectiveness of Exablate thermal ablation of a focal epileptic target area in the brain of patients suffering from medication-refractory epilepsy, using the Exablate transcranial system to produce multiple sonications targeted in the focus of interest. The investigators will establish the feasibility and collect data to establish the basic safety of this type of treatment as the basis for later studies that will evaluate its full clinical efficacy.
The goal of the present study is to evaluate ("screen") a large number (12) of different dual therapies of perampanel + another AED ("PMP+") for a large, 75-100% seizure frequency reduction. The design of the study will differ from usual AED studies. The study will be (i) open label, with (ii) a small n per group, n=6, with (iii) outcome measures a 'blockbuster effect': (a) ≥75 seizure frequency reduction; and (b) seizure freedom.
