Filter by:The aims of study on KCNQ2-related epilepsy: (1) establish phenotype database and sample database of KCNQ2-related epilepsy; (2) to establish genotype-phenotype association of KCNQ2-related epilepsy; (3) to study the brain network of KCNQ2-related epilepsy based on multi-modal brain image and EEG data; (4) to find prognostic biomarkers of KCNQ2-related epilepsy based on omics study.
This proposal outlines the steps required for the creation of a pilot database of EEG recordings and de-identified medical records from patients internally referred within the UNMH Comprehensive Epilepsy Center. The UNMH EEG Corpus would be the first database of its kind. Other public databases contain either patient EEG signals or medical records, but without both kinds of information, it is impossible to relate pre-treatment neurobiomarkers with post-treatment prognosis. The database will also contain information that can improve seizure localization based off of scalp and intracranial EEG, and the requisite data for the creation of algorithms that forecast seizure activity; a development that could ultimately lead to novel responsive neural stimulation procedures that suppress seizures before they begin.
This clinical trial is designed to test whether a single stereotactic intracerebral administration of inhibitory nerve cells into subjects with drug-resistant mesial temporal lobe epilepsy is safe (frequency of adverse events) and effective (seizure frequency).
In order to increase adherence to ketogenic diet treatment, palatability of meals and diversify the foods offered to patients a ketogenic kitchen will be created. Intervention: Incorporation of culinary workshops and supply of recipes for patients undergoing ketogenic diet treatment at Instituto da Criança - HCFMUSP.
This trial is a Phase II randomized, double-blind, placebo controlled multi-site study to evaluate the safety and efficacy of early sirolimus to prevent or delay seizure onset in TSC infants. This study is supported by research funding from the Office of Orphan Products Division (OOPD) of the US Food and Drug Administration (FDA).
Deep brain stimulation (DBS) has become a gold-standard symptomatic treatment option for Parkinson's disease (PD) and is also explored for a variety of other neurological disorders. The implantation of electrodes into deep brain areas has not only enabled the application of electrical stimuli, but has also provided researchers and clinicians with an unprecedented window to investigate aberrant neuronal activity right at the core of pathological brain circuits. Local field potentials (LFP) have already been readily investigated through externalised DBS electrode wires prior to internalisation and connection to an implantable neurostimulator. In the case of PD, motor symptoms have been evidenced to correlate with exaggerated beta oscillatory activity (13-35 Hz) in the LFP recorded from the subthalamic nucleus (STN). Firstly, beta activity recorded in the STN at rest in patients withdrawn from their medication has been correlated with the Unified Parkinson's Disease Rating Scale (UPDRS) across patients. Secondly, a reduction of signal power in the beta-band was correlated with clinical improvements of motor symptoms. Thirdly, the two main therapeutic strategies, the administration of L-Dopa, and high-frequency DBS both lead to a suppression of beta-synchronicity in the STN. Furthermore, beta-oscillations show fast and movement-dependent modulation over time and can serve as a biomarker and feedback signal to control the delivery of DBS. The investigators recently implemented deep brain electrical neurofeedback to provide real-time visual neurofeedback of pathological STN oscillations through externalised DBS electrodes and showed that PD patients were able to volitionally control and reduce subthalamic activity within a single 1 hour session. Moreover, neurofeedback-learnt strategies accelerated movements and could be retained in the short- and mid-term. Only recently, a newly developed neurostimulator, the Percept™ PC (Medtronic Neurological Division, Minneapolis, MN, USA), has been clinically approved, which can not only apply electrical impulses, but also enable the measurement and transmission of brain activity. This neurostimulator is now the first choice for implantations at the University Hospital Zurich and is used for a variety of neurological disorders. The investigators' goal is to investigate whether neurofeedback through a fully implanted deep brain stimulation device is possible and can lead to a better control of pathological oscillations as well as symptom mitigation. Having shown that endogenous control over deep brain oscillations is possible, the investigators will also test this novel therapeutic approach for pathologies other than PD that are also treated with DBS. Neurofeedback using implanted DBS electrodes will have the advantage of enabling longer and multiple-day training sessions, which the investigators hypothesise to have a larger impact on control over pathological deep brain oscillations and neurological symptoms, as such a fully implanted neurofeedback system no longer requires the externalisation of DBS wires and is as such no longer limited to the first two days after electrode implantation. All in all, the investigators will not exceed a total streaming time of 7 hours per patients (7 d of battery time), which the investigators deem justifiable with respect to a battery life of > 5 years. This proposed research is highly significant as it will help our understanding of various neurological diseases that are highly prevalent in society (PD being, for instance, the second most common neurodegenerative disorder after Alzheimer's disease) and might culminate in novel, endogenous treatment strategies. The overall risk for patients is minimal to non-existent, as stimulation parameters are unaffected and the intended changes in brain activity are self-induced while DBS stimulation is off.
Multicentre cross-sectional study with prospective recruitment comparing the detection rate of lesions on brain MRI without and with quantitative volumetry and T1 relaxometry information during the management of children with suspected focal epilepsy.
The goal is to develop methodology to monitor flux in the citric acid cycle in brain via 13C nuclear magnetic resonance (NMR) spectroscopy at 7 Tesla.
This is a two-arm randomized controlled trial to compare telephone-based depression self-management (UPLIFT) to telephone-based support groups (BOOST). A sample of 120 English- and Spanish-speaking people with epilepsy (PWE) with elevated depressive symptoms will be enrolled. Both interventions are 8-week programs delivered in one-hour weekly sessions to groups of about 6 participants. Changes in depressive symptoms, quality of life and seizures will be assessed over 12 months. The trial will also examine mediators and moderators of treatment effects.
The current project undertakes a prospective multicentre randomised controlled trial to evaluate whether full or continuous electroencephalography (cEEG) is superior to amplitude-integrated electroencephalography (aEEG) in the real time evaluation and diagnosis of neonatal seizures and in reducing time to treatment. At-risk new-born infants will be recruited on the participating neonatal intensive care units (NICUs) by trained specialist staff and will have 24 hours of EEG monitoring.
