Filter by:This project aims to conduct a pilot study based on the targeting of the epileptogenic zone previously localized very precisely by stereoelectroencephalography (SEEG). SEEG is used as part of the pre-surgical assessment. It consists, thanks to the intracerebral implantation of electrodes in the brain of patients, to perform an intracerebral electrophysiological recording and thus to precisely explore the epileptogenic regions. In order to study the neuromodulatory and therapeutic effects of tDCS on epileptic brains, non-invasive techniques for measuring electrophysiological brain activity such as magnetoencephalography (MEG) and high-resolution electroencephalography (HR EEG) will be used. Finally, since epilepsy is considered to be a disorder of brain functional networks associated with disturbed brain connectivity, the effects of tDCS on cortical excitability by studying the variations in functional connectivity induced by stimulation will be studied.
This study aims to investigate the effect of a short-term prescription of ciprofloxacin on intestinal microbial pattern and seizure frequency of patients with drug-resistant epilepsy.
The study is investigating if following the low glutamate diet for 1 month, as compared to care as usual, can improve seizure frequency, severity, and duration; cognitive functioning; and/or quality of life in children with epilepsy.
For 28 days, 30 participants aged 3 to 18 years of age (inclusive) with a condition requiring a ketogenic diet will incorporate Ketoflo into their usual dietary regime. Ketoflo is a nutritionally complete Food For Special Medical Purposes and is suitable for administration by both tube feeding and use as a sip feed. Data on gastrointestinal tolerance, participants adherence to recommended intakes and their thoughts on the product's palatability will be self-reported in Daily Study Diaries.
This is a parallel-arm, double-blind, placebo-controlled study with a screening phase that includes a 28-day run-in phase to establish baseline seizure frequency, followed by a 24-week, randomized, placebo-controlled phase. After completion of the randomized, placebo-controlled phase, participants may enter a 48-week, long-term, extension phase during which they will receive open-label treatment with vatiquinone.
This is a multicenter, non-blinded, patient preference comparative trial for efficacy of deep brain stimulation (DBS) on drug-resistant epilepsy compared to continued vagal nerve stimulation (VNS) optimization in children with failed VNS. The two conditions being compared are therefore DBS (treatment) versus VNS (control). Fifty (50) patients will be recruited and enrolled in this pilot study (25 from The Hospital for Sick Children and 50 from CHU Sainte-Justine).
Over 1 million people in the European Union (EU) suffer from chronic refractory epilepsy. Their quality of life (QoL) is severely affected by seizures and by the adverse effect of antiepileptic drug (AED) treatment. Several new AEDs have been introduced in recent years, but their impact on the long-term outcome in these patients has been inadequately explored. Preliminary data from the U.S. suggests that using a standardize toll to quantitate adverse AED effects can improve outcome, but the general applicability of these findings is unclear. Objectives: 1) To assess prospectively AED utilization patterns in patients with refractory epilepsy ; 2) to assess how such treatments and other variables correlated with seizure control, adverse effects, and QoL in these patients; 3) to establish the impact of a standardized evaluation of adverse effects on clinical outcome. Methods: The project included a core observational study and a randomized intervention in a subcohort. In the core (observational) study, 1,000 consecutive refractory epilepsy patients were enrolled and followed-up prospectively at 10 centres in Italy. The following parameters were recorded at 0 (entry), 6, 12 and 18 months: (i) drug therapy; (ii) seizure frequency; (iii) adverse events based on medical examination and non-structured interview; (iii) treatment costs and, (iv) for patients above age 16, standardized questionnaires for adverse effects (AEP), depressive symptoms (Becks Depression Scale, BDS), QoL (QOLIE-31) and clinical global impression (CGI). The primary outcome (changes in QOLIE-31 scores) will be related to the other variables measured. In the randomized intervention, the subcohort meeting specific eligibility criteria (age >16 years, no progressive disorder, AEP score>=45 ) was randomized to two groups. In the intervention group, AEP score results were made available to the physician at each visit, while in the other group AEP scores were only made available at the end of follow-up. Primary outcome were changes in AEP score.
This study is to evaluate the safety and the intracranial electroencephalography (iEEG) changes of using NaviFUS System for the treatment of patients with drug resistant epilepsy.
Refractory epilepsies caused by an autoimmune mechanisms lead in children to progressive neurodegeneration. Immunomodulation therapy is effective only in a half of such cases. New approaches are undertaken. It was found that ADRC (adipose derived regenerative cells) isolated from adipose tissue consist mesenchymal stem cells that act as tissue repair cells. The purpose of this experimental study is to evaluate the possibility and safety of the use of multipotent mesenchymal adipose derived regenerative cells (ADRC) in patients diagnosed with an autoimmune determined refractory epilepsy. Study protocol: Intrathecal infusions of autologous ADRC obtained after liposuction followed by isolation by Cytori system will be performed. Procedure will be repeated 3 times every 3 months in each patient. Neurological status, brain MRI, cognitive function and antiepileptic effect will be supervised during 24 months.
This is a prospective, single-center, phase 1 safety study to investigate the safety, tolerability, seizure control, and quality of life in participants with medically-refractory epilepsy who failed epilepsy surgery. These participants will have continued seizures despite being at least 3 months post-epilepsy surgery (resective surgery with an intent to cure).
