Filter by:Epilepsy is frequently associated with cognitive and attentional disorders. Several studies have pointed out that there are modifications of brain activity in resting state during peri-ictal period in EEG and functional MRI. However, to date, no study has assessed the changes in attentional control after a seizure. The investigators hypothesize that a localized discharge is associated with a disorganization of the networks engaged in attentional control. In this regard, the investigators propose a prospective longitudinal study assessing the changes in attentional control after a focal seizure.
The study aimed at detection of autonomic dysfunction among cases with temporal lobe epilepsy; using different electrophysiological techniques. Moreover, it aimed at finding any correlation between electrophysiological tests and SUDEP risk.
Temporal Lobe Epilepsy (TLE) patients and healthy controls will undergo a night of sleep at the UC Davis Epilepsy Monitoring Unit (EMU) to characterize sleep architecture. A subset of TLE patients will be randomly assigned to an Acoustic Stimulation (AS) or SHAM stimulation night and return at least 7 days later for the other condition. Cognitive tests will be conducted 90 minutes prior to sleep (learning and immediate recall) and again 1 hour after awakening for 120 minutes (delayed recall and attention), while monitoring neural networks using functional Magnetic Resonance Imaging (fMRI).
Out of 30,000 new cases per year in France, 30% of epileptic patients are drug-resistant. Neurosurgery, which consists in resecting the epileptogenic zone, is the only chance of cure. In the case of temporal epilepsy of the language-dominant hemisphere (TLE), this procedure presents a high risk of increasing cognitive difficulties and may even be contraindicated for this reason alone. The difficulties found are impairments in lexical access (anomia) and verbal memory and affect more than 60% of patients . Preoperative cognitive rehabilitation could influence brain plasticity mechanisms but there are currently no recommendations on this topic. In this context, the investigators have developed a speech rehabilitation procedure specific to the needs of ELTPR patients. They rely on cognitive hypotheses explaining the disorders but also on models of rehabilitation-induced neural plasticity likely to improve cognitive reserve before surgery. The investigators hypothesize that preoperative cognitive language rehabilitation in ELTPR patients may decrease surgical risk and improve postoperative language prognosis. The primary objective is to demonstrate the protective efficacy of preoperative speech rehabilitation on language performance postoperatively.
Nearly 100 million Americans are affected by neurological disorders with an overall cost above $765 billion for the more prevalent conditions. Given this significant burden, effective treatments to prevent dementia and new disease modifying therapies are urgently needed. Regeneration of lost neurons with new ones (i.e., neurogenesis) is compromised at early stages of dementia and in part correlates with cognitive impairment in Alzheimer's disease. Boosting the neurogenesis delays the cognitive impairment in animal models of dementia and has been proven beneficial in improving the memory in rodent studies. Aerobic exercise is the most potent known stimulator of neurogenesis in animal models. A crucial next step is to translate endogenous regenerative strategies to people. The purpose of this study is to demonstrate the feasibility and investigate the effects of an exercise program on neurogenesis and cognitive improvement in epilepsy patients.
This is a single-centre pilot study of a non-invasive auditory stimulation during sleep in participants with temporal lobe epilepsy.
Temporal lobe epilepsy (TLE) is a chronically neurological disease characterized by progressive seizures. TLE is the most frequent subtype of refractory focal epilepsy in adults. Epilepsy surgery has proven to be very efficient in TLE and superior to medical therapy in two randomized controlled trials. According to the previous experience, the investigators use functional anterior temporal lobectomy (FATL) via minicraniotomy for TLE. To date, this minimally invasive open surgery has been not reported. The investigators here present a protocol of a prospective trail which for the first time evaluates the outcomes of this new surgical therapy for TLE.
We aim to o evaluate the role of conventional and advanced MRI sequences in diagnosis of idiopathic temporal lobe epilepsy including identification and lateralization of epileptogenic focus.
The study is a two-phase study, which aims to explore the uses of a novel electrode type in detecting epileptic seizures. The electrode is designed for subcutaneous implantation with long-term monitoring in mind.
The study is designed to evaluate the safety and efficacy of the Visualase MRI-guided laser ablation system for mesial temporal epilepsy (MTLE).
