Filter by:The purpose the research is to better understand how the human brain accomplishes the basic cognitive tasks of learning new information, recalling stored information, and making decisions or choices about presented information. These investigations are critical to better understand human cognition and to design treatments for disorders of learning and memory.
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.
The aim of this study is to investigate the effects of cathodal transcranial direct current stimulation in the management of seizures in subjects with focal refractory epilepsy.
The purpose of this research is to understand biomarkers of human memory through correlational analyses and to use focal electrical stimulation as a causal manipulation to understand how biomarkers of memory relate to other brain states and behavioral measures.
People with central lobe epilepsy (CLE), with seizures arising from the primary sensorimotor cortex, typically show a high rate of convulsive seizures that do not respond to anti-epileptic drugs, but have a large impact on quality of life. They often seek surgical relief, but since the area contains the body's indispensable sensorimotor representation, CLE surgery will lead to permanent functional deficits. Cortical stimulation case studies in CLE have shown seizure frequency reduction of more than 90%, but in our experience, stimuli in the central lobe can hardly be applied without interfering with motor function. The investigators propose cortical electrical stimulation therapy of a conceptually novel type. The investigators systematically determine individual stimulation settings, stimulation site and a seizure detection algorithm. In REC2Stim (Rational Extra-eloquent Closed-loop Cortical Stimulation), at the start of a seizure, a train of electric pulses is delivered to a nearby extra-eloquent area connected with the epileptogenic area within the sensorimotor cortex. Success will constitute a therapeutic modality for pharmaco-resistant patients with an epileptic focus in eloquent areas.
Epilepsy is a disorder of the brain which is associated with disabling seizures and affects 100,000 people under 25. Many children with epilepsy also have a learning disability or problems with development. Although better outcomes occur in children who are successfully treated early for their epilepsy, 25% continue to have seizures despite best medical treatment. One potential treatment is a neurosurgical operation to remove parts of the brain that generate seizures. A proportion of these children have electrodes inserted into their brains as part of their clinical assessment, termed stereoelectroencephalography (SEEG), to help localise these regions. Subsequent surgery is not always successful - up to 40% of children will have ongoing seizures 5 years after surgery. The purpose of this study is to assess the utility of specially designed SEEG electrodes which can measure signals from single brain cells. These electrodes record the same clinical information as normal SEEG electrodes and are implanted in the same way, but can give the research team extra information at the same time. The investigators aim to assess whether studying the changes in the firing of individual cells, both during and between seizures, improves our ability to localise seizures and therefore improve outcomes following surgery. As part of this research project, the investigators will not be doing anything that is not already part of the normal investigation and treatment for these children. Children will be recruited to the study during routine outpatient clinic visits. Surgical planning and execution will not be affected. The electrodes are CE licensed for clinical use and do not alter the risks of the operation. Following the period of monitoring, the care of these children would not be altered in any way. The investigators aim to recruit 30 patients over 3 years. In addition to dissemination via scientific publications and presentations, the findings will be shared with participants and the public.
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.
The purpose of this study is to obtain preliminary data in advance of a larger clinical trial aimed to test whether a single session of green light exposure can lead to a clinically significant reduction in epileptic spikes in patients with medically-refractory epilepsy. As this is a potentially fragile patient population, the study will test safety and tolerability as well as efficacy.
The purpose of this pilot study is to measure adherence and quality of life in adults with intractable epilepsy following the Modified Atkins Diet (MAD) with Betaquik, a ready-to-use medium chain triglyceride (MCT) emulsion, as an adjunct to the MAD.
This is an open label, randomized, prospective study of the impact on healthcare utilization of a surface Electromyography (sEMG) based seizure monitoring and alerting system for Veterans with seizures with upper extremity motor involvement, that are refractory to three or more antiepileptic drugs.
