Filter by:The purpose of this research is to search for reproducible changes in a wide range of physical signals, including heart rate, muscle tone and activity and EEG before and at the onset of seizures in patients with epilepsy.
This is a Phase 3, global, open-label extension (OLE) study of adjunctive GNX treatment in children and adults with TSC who previously participated in either Study 1042-TSC-3001 or Study 1042-TSC-2001
The presence of a damage to the central and / or peripheral nervous system resulting from diseases of a different nature (such as, Multiple Sclerosis, Parkinson's disease, dementia, head trauma, stroke, epilepsy or other neurological syndromes) is commonly cause of both physical than mental disability. The evaluation of certain domains may be more difficult so, specific assessment tools are necessary to analyze them.
The basic mechanisms underlying comprehension of spoken language are still largely unknown. Over the past decade, the study team has gained new insights to how the human brain extracts the most fundamental linguistic elements (consonants and vowels) from a complex and highly variable acoustic signal. However, the next set of questions await pertaining to the sequencing of those auditory elements and how they are integrated with other features, such as, the amplitude envelope of speech. Further investigation of the cortical representation of speech sounds can likely shed light on these fundamental questions. Previous research has implicated the superior temporal cortex in the processing of speech sounds, but little is known about how these sounds are linked together into the perceptual experience of words and continuous speech. The overall goal is to determine how the brain extracts linguistic elements from a complex acoustic speech signal towards better understanding and remediating human language disorders.
To examine the effects of haloperidol, chlorpromazine, valproic acid and placebo, in conjunction with standardized non-pharmacologic interventions, in the first line treatment of agitated delirium in hospitalized patients with cancer. This double-blind, randomized clinical trial aims to provide evidence on various therapeutic options for palliating delirium, thereby reducing delirium-related distress and ultimately alleviating suffering.
Sudden unexpected death in epilepsy (SUDEP) is regarded as a leading cause of premature death in epilepsy patients. We aim to capture the whole process of SUDEP and near-SUDEP occurrence in patients with epilepsy, and expolre video-electroencephalograph (V-EEG) changes and marker. A Chinese multicenter study was carried out to determine electroencephalo-graph marker related to SUDEP to provide a scientific basis for the prevention of SUDEP in patients with epilepsy.
Previously, scholars called the seizures secondary to autoimmune encephalitis（AE） "autoimmune related epilepsy", but the seizures secondary to AE are usually controlled after the improvement of encephalitis, which does not meet the "persistent" characteristics of epilepsy. Only a subset of patients with seizures lasting several years require long-term Antiseizure medications (ASM). In 2020, the International Coalition against Epilepsy classified it as "acute symptomatic seizure secondary to AE". ASSAE) and autoimmune-associated epilepsy (AAE) . The former is caused by AE, which has clinical manifestations of AE at the same time as epileptic seizures at the beginning or recurrence. The proportion and type of epileptic seizures are different due to different causes, and epileptic seizures are also controlled after the disease is controlled. The latter is that after adequate immunotherapy, there are still persistent seizures, and there is no obvious evidence of inflammatory activity, this type of patient application ASM and immunotherapy is not effective. Secondly, with the deepening of AE research, gradually found that some AAE can still be ASMs cure, such as carbamazepine, ocasepine, lakaosamine. On the one hand, it works by influencing cellular and humoral immune responses. On the other hand, effectiveness of sodium channel blockers in focal epilepsy. Lacosamide is a slow sodium channel blocker that belongs to the third generation of ASM. It has a short half-life and can be quickly increased to an effective dose with a low incidence of adverse reactions. Therefore, the investigators chose to add oral antiepileptic therapy with lacosamide in AAE populations to observe efficacy and safety.
The goal of this study is to measure the activation of the vagus nerve and the side effects of vagus nerve stimulation (VNS) (neck muscle contractions, changes in heart rate) across a range of stimulation parameters typically used in VNS therapy for epilepsy (pulse durations, pulse amplitudes, pulse repetition rates). This mapping of the parameter space may inform future device programming to improve electrical activation of the vagus nerve and/or to reduce side effects, and it may be used for validation of computational models. The study will recruit adult participants with epilepsy who are undergoing surgery either for an initial implant of a VNS device or for replacement of the implanted pulse generator (IPG) due to battery depletion. During surgery, the study will involve stimulating the vagus nerve via the standard implanted clinical VNS electrodes over a range of stimulation parameters while recording the activity of the vagus nerve (electroneurogram (ENG)), electromyogram (EMG) response of neck/throat muscles, and the heart rate (electrocardiogram (EKG)). Stimulation parameters will be within the ranges used for clinical therapy and below limits established for non-damaging electrical stimulation.
This study will improve access of Veterans with epilepsy living in rural areas to the most important diagnostic procedure for the care of patients with epilepsy: the routine electroencephalogram (EEG). The investigators will test a new method for recording EEG which uses a novel dry electrode system headset that does not require an EEG technologist to operate. The headset integrates the EEG electrodes and amplifier into a compact system which is easily placed on the head. This approach could make it possible for a nurse or nurse assistant with minimal training to record an EEG in a rural community based outpatient clinic (CBOC) as part of an epilepsy telemedicine outreach program along with clinical interviews. The investigators will compare performance of this dry electrode system to standard EEG when it is used by EEG technologists in three VA medical centers. This project has the potential to improve access of Veterans to the EEG procedure and decrease cost to the Veterans Health Care System.
The ketogenic diet (KD) represents an effective and safe non-drug treatment for drug-resistant epilepsy in pediatric and adult age based on normocaloric, hyperlipidic (80-90% of the daily energy), normoproteic and hypoglucidic dietary regimen. Adherence to treatment with KD is often difficult in the long term, for the patient and for caregivers, especially in adolescence. There are no tools in the literature other than monitoring ketonemia to measure adherence to the diet. A quality tool, validated by experts, on a large population, would allow for a more solid assessment of adherence to treatment, facilitating clinicians in the interpretation of efficacy results and in implementing an early intervention to adjust the therapy.
