Filter by:The study aims to evaluate the effectiveness of long-term video EEG monitoring using 10-20 electrodes extended with intra-auricular electrodes in locating the seizure onset zone and interictal epileptiform discharges (IEDs) in patients with temporal lobe epilepsy (TLE) and nontemporal lobe epilepsy (non-TLE).
This is a national monocentric (San Raffaele Hospital - OSR, Via Olgettina, 60, 20132 Milan, Italy) observational low-risk-intervention study, prospective and multiparametric (clinical, EEG, neuropsychological evaluations) study. Patients with a diagnosis of DRE and DSE will be screened to evaluate their eligibility. They will undergo clinical and cognitive assessments in addition to 32channel EEG at baseline (T0). DRE patients will also undergo clinical and cognitive assessments, and 32-channel EEG at 6 months (T1), and 12 months (T2). Patients newly diagnosed with focal cryptogenic epilepsy (NDE) will undergo clinical and cognitive assessments, and 32-channel EEG at baseline (T0), at 6 months (T1), and 12 months (T2). High-definition EEG will be performed to investigate patterns of cortical sources and functional connectivity alteration specific to DRE and DSE and to explore their prognostic value. Longitudinal EEGs will be acquired to explore the evolution of EEG patterns. Cognitive evaluation will be performed by an experienced neuropsychologist. At baseline, DRE, DSE, and NDE patients will undergo a screening and a comprehensive cognitive battery in order to define performance differences among groups. The DRE and NDE group only will perform the same neuropsychological assessment at month 6 and 12 for monitoring the potential progression of cognitive and/or behavioural disturbances in these patients.
The objective of this prospective interventional monocentric clinical investigation is to evaluate the feasibility and performance of the flexible high-density SOFT ECoG electrode grids, manufactured by Neurosoft Bioelectronics SA (test device; TD), in comparison to regular high-density electrode grids (ADTech, CE-marked) (control device; CD) routinely used at the investigation site during epilepsy surgery. Subjects will undergo ≥ 2 additional intracranial recordings pre- and post-resection with the TD next to the standard recordings with the CD during ECoG-tailored epilepsy surgery.
Epilepsy is a disabling neurological disease that affects tens of millions of people worldwide. Despite therapeutic advances, about a third of these patients suffer from treatment-resistant forms of epilepsy and still experience regular seizures.All seizures can last and lead to status epilepticus, which is a major neurological emergency. Epilepsy can also be accompanied with cognitive or psychiatric comorbidities. Reliable seizures count is an essential indicator for estimating the care quality and for optimizing treatment. Several studies have highlighted the difficulty for patients to keep a reliable seizure diary due for example to memory loss or perception alterations during crisis. Whatever the reasons, it has been observed that at least 50% of seizures are on average missed by patients. Seizure detection has been widely developed in recent decades and are generally based on physiological signs monitoring associated with biomarkers search and coupled with detection algorithms. Multimodal approaches, i.e. combining several sensors at the same time, are considered the most promising. Mobile or wearable non invasive devices, allowing an objective seizures documentation in daily life activities, appear to be of major interest for patients and care givers, in detecting and anticipating seizures occurence. This single-arm exploratory, multicenter study aims at assessing whether the use of such a non-invasive, wearable device can be useful in a real life setting in detecting seizures occurence through multimodal analysis of various parameters (heart rate, respiratory and accelerometry).
This is a study which seeks to develop a novel therapeutic approach, Intersectional Short Pulse (ISP) stimulation for seizure termination. The device embodiment of ISP is a scalp EEG recording system which also delivers spatially precise electrical stimulation in short pulses to the targeted brain region. The study team has already collected safety and tolerability data in human subjects, demonstrated ISP efficacy in terminating seizures in rodents, and have tested the efficacy of this device to modulate normal human brain activity. Now this study proposes to test the device's efficacy in stopping seizures in a within-subject randomized, sham-controlled study design.
The main goal of this project is to study the mechanisms of epileptic activities using intracranial macro and micro electrodes in epileptic patients undergoing pre-surgical investigation. The recordings will also be used to study physiological mechanisms like sleep and different cognitive functions.
