Filter by:This study wants to make it easier to find kids with a type of epilepsy called childhood absence epilepsy (CAE) who might have problems with ongoing seizures and thinking. Right now, doctors use tests that can be expensive and take a long time. Eysz is developing a system that looks at how kids move their eyes which might help find CAE more quickly and accurately. This study will compare Eysz with the usual tests to see if it can predict seizures and thinking problems in kids with CAE. The goal is to find these problems earlier and help kids do better in school and life.
The purpose of this study is to determine whether BHV-7000 is effective in the treatment of refractory focal epilepsy.
Epileptic seizures in newborns (often called "neonatal convulsions") represent the most frequent neurological problem in newborns (1-3/1000 newborns). The type of seizure and their etiology is very varied and therefore the therapeutic protocol also requires adaptations with a personalization of the therapeutic approach according to the characteristics of the case according to principles of precision medicine in particular for forms of neonatal epilepsy compared to epileptic seizures acute symptomatic. In recent years it has been highlighted that the clinical characterization and instrumental characterization, in particular electroencephalographic, of epileptic seizures represents an important biomarker that allows the choice of therapy to be oriented appropriately. In the literature there is a lack of single-center studies that relate the type of crisis according to the new ILAE 2017 classification (Fisher 2017) and its proposal for neonatal adaptation (Pressler 2021) with the etiology, type of therapy and outcome neurological after a few years. The primary aim of the study is to evaluate the correlation between the type of seizure determined according to the ILAE classification (clinical variables), the EEG findings of the epileptic seizures and the specific etiology of the epileptic seizures. The secondary aim is to evaluate the correlation between seizure type and etiology with effective therapy, length of hospitalization and neurobehavioral development outcome. The study design is a retrospective observational on the population of neonates managed at our center in the last decade.
Vagus nerve stimulation (VNS) is an adjunctive treatment for refractory epilepsy. Although widely used, there is still a substantial number of patients with insufficient response. Light, and particularly blue light, can stimulate alertness, attention and cognition through modulation of anatomical targets which are common to the vagal afferent network. This project aims at understanding how exposure to blue enriched light may influence VNS effects in patients with refractory epilepsy by exploring the modulation of a series of biomarkers of VNS action. This could possibly lead to new therapeutic strategies to increase efficacy of VNS.
This study was planned as a randomized controlled experimental study with a pretest-posttest design to determine the effect of parental supervision and video-guided progressive relaxation exercise (PRE) and music recital on sleep, quality of life and emotional states in children with epilepsy aged 9-16 years. The main questions it aims to answer are as follows: According to the evaluation of children with epilepsy, does the progressive relaxation exercise applied to children have an effect on sleep, quality of life and emotional states? According to the evaluation of children with epilepsy, does music recital applied to children have an effect on sleep quality of life and emotional states? The study consisted of 45 children (15 children in the progressive relaxation exercise group, 15 children in the music recital group and 15 children in the control group). Ethics committee approval, permission from the institutions and informed consent of the children were obtained for the conduct of the study. A value of p<0.05 was considered statistically significant in data analysis.
Background. Seizures are a common cause of evaluation in the pediatric emergency department (ED). Several studies about the impact of COVID-19 pandemic on ED attendances report a considerable reduction in general pediatric care. The aim of our study was to evaluate the impact of COVID-19 on the admission to the pediatric ED for seizures. Materials and methods. We performed a retrospective study to assess the rate of ED admission for seizures at the pediatric ED of the Fondazione IRCCS Ca' Granda Ospedale Maggiore Policlinico of Milan between January 2017 and December 2021, comparing the pre-pandemic (from January 2017 to February 2020) and pandemic periods (from March 2020 to December 2021).
Focused ultrasound (FUS) has been shown to differentially lesion or modulate (excite and inhibit) brain circuit and neural activity across a broad range of acoustic stimulus parameters (intensity, duty cycle, pulse repetition frequency and pulse duration) for decades. From our previous study, FUS sonication may suppress the number of epileptic signal bursts observed in EEG recordings after the induction of acute epilepsy. The presence of the suppressive effect was found in terms of the number of epileptic EEG spikes from the analysis of the unfiltered and theta-band EEG activity, and further discontinue the seizure attacks. EEG activity has also been consistently reported to have a positive correlation with the level of epilepsy, and FUS-mediated reduction of epileptic EEG activity was most notably observed, no matter lesioning or modulating effects. The aims of this study are to demonstrate the safety and efficacy of FUS technology in epilepsy patients and to estimate the optimal parameters of focused ultrasound exposure that will be used in the case of epilepsy.
Transcranial magnetic stimulation (TMS) uses electromagnetic induction as an efficient, painless, non-invasive method to generate a suprathreshold current at the level of the encephalon, and provide in vivo measurements of cortical excitability and reactivity at the level of the motor cortex (TMS-EMG) or the entire cortical mantle (TMS-EEG). This study proposes TMS measurements as a diagnostic tool in patients to understand mechanisms of epileptogenesis related to genetic mutations, and prognostic to guide and monitor precision treatments.
This study is a non-randomized, open label, phase 1 clinical trial to evaluate the fesibility and safety of intrathalamic delivery of MSCs during standard of care DBS surgery for epilepsy. Subjects will be screened at our outpatient clinic and interested qualified subjects will be consented and offered participation in this trial. Once consent has been obtained, patients will undergo a standard preoperative evaluation which includes baseline laboratory values and a high-definition MRI. Patients will then undergo a stereotactic procedure for bilateral thalamic implantation of DBS leads through the ClearPoint® system. After the thalamic target for DBS is identified, cells will be infused directly into the anterior nucleus of the thalamus previous to lead implantation. Patients will be followed in the outpatient setting for up to a year after therapy application. Surgical, clinical, and radiographic data will be obtained during these visits
This study investigates the usefulness of high resolution electrical source imaging (HR-ESI) in the setting of presurgical evaluation of drug-resistant focal epilepsy in children. This method is based on an estimation of the intra-cerebral source that produces a signal recorded by scalp electrodes by solving the inverse problem, taking into account attenuation factors resulting from particular conductivity properties of the cerebral, peri-cerebral and cranial tissues. Electrical sources are then fused on structural magnetic resonance imaging (MRI). Scalp EEG recorded using 64 to 256 electrodes refers to as high resolution EEG (HR-EEG), leading to HR-ESI. Studies based on small population of children or on mixt population of children and adults showed that HR-ESI has accuracy values, i.e. percentage of true positives (electrical source localized in the brain area resected and success of surgery) and true negatives (electrical source localized outside the brain area resected and failure of surgery) among the total population, ranging from 50 to 80%. Discrepancies between studies could be explained by the limited number of patients included or by the mixture of pediatric and adult data. Another limitation of previously published studies is that the spatial pattern of dipole source distribution was not taken into account to determine prediction accuracy of ESI. Studies using magnetoencephalography (MEG) to perform magnetic source imaging (MSI) suggest that the spatial pattern of dipole source distribution needs to be considered, a spatially-restricted dipole distribution being associated with better post-surgical outcome when resected. To tackle these issues, the investigators aim to conduct the first large prospective multicentric study in children with focal epilepsy candidates to surgery to assess prediction accuracy of ESI based on the finding of tight clusters of dipoles. This is original as this pattern (tight versus loose cluster of dipoles) has been studied by several researchers using MEG but not using HR-EEG. The investigators make the hypothesis that HR-EEG will allow to identity good candidates for epilepsy surgery and thus to offer this underutilized treatment in more children with better post-surgical outcome. Among the secondary objectives, the investigators will address methodological issues related to the resolution of the inverse problem (methods using distributed sources models versus methods based on equivalent dipole estimation), the potential added value to model high-frequency oscillations (HFO), and the investigators will assess the cost-utility of the HR-ESI procedure.
