NCT ID: NCT03570489 Terminated - Refractory Epilepsy Clinical Trials

Randomized Controlled Trial on Cardiovascular Exercise in Uncontrolled Epilepsy:

Epilepsy
Start date: November 30, 2018
Phase: N/A
Study type: Interventional

This is an open-label randomized controlled tria testing if an improvement in cardiovascular fitness can improve quality of Life and reduce seizure frequency in patients with refractory epilepsy.. Before the intervention each subject will undergo an evaluation of baseline cardiovascular fitness. Patients will be randomized into two groups One group will listen to a relaxation tape 5 days per week for 6 months and the other group will receive a ergometric cycle and perform a predetermined level of exercise per day , 5 days per week for 6 months. Randomization will be conducted an external randomization center based on a sequence of random numbers. Changes in concomitant antiepileptic drugs (AED) treatment during the study will be minimized, and restricted to AED changes deemed to be necessary to address AED-related toxicity. Medical examination; body weight; fitness test, including ECG and BP measurements, seizure frequency; adverse effects (unstructured interview); details of concomitant concomitant treatment, mood assessment by using the Hospital Anxiety and Depression Scale-Anxiety (HADS); health related quality of life (RAND-36), E4-data downloading, will be done at baseline and after 6 months Primary endpoint: Proportion of patients with at least 50% seizure reduction Secondary endpoints: Median percent reduction in seizure frequency, HADS score, RAND-36 score, fitness score; adverse events, changes in concomitant AED treatment, E4 data .

NCT ID: NCT03331939 Terminated - Refractory Epilepsy Clinical Trials

Effect of Short-term Theta Frequency Stimulation of the Vagus Nerve on Cognition in Patients With Refractory Epilepsy

Start date: January 6, 2017
Phase: N/A
Study type: Interventional

The purpose of this investigation is data pilot study of the effect of theta frequency stimulation of the vagus nerve on cognitive performance in patients with refractory epilepsy. We will compare the effects of no stimulation, theta frequency (5 Hz), and 'standard' beta frequency stimulation (25-30 Hz) on cognitive measures. We hypothesize that theta frequency VNS will have a positive effect on memory retention. The goal of this study to provide initial data to inform the design of a larger clinical trial to examine the efficacy of theta VNS.

NCT ID: NCT03318237 Terminated - Epilepsy Clinical Trials

Ultra High Field MRI of Focal Pediatric Epilepsy

Start date: May 1, 2018
Phase:
Study type: Observational

Epilepsy affects a significant number of children in the United States. The majority of patients achieve control of their seizures by conventional treatment strategies including medications. However, one third of patients do not achieve satisfactory seizure control with medications alone. Ketogenic diet and lifestyle modifications may also be tried. In some of these children, the seizure focus can be localized to one area of the brain and the seizures are resistant to conservative treatment strategies. These children may have subtle structural/developmental abnormalities in their brain, the most frequent of which is focal cortical dysplasia. These are localized areas of abnormal lamination of the cerebral cortex that can be extremely subtle and difficult to detect, even with state of the art magnetic resonance imaging (MRI). More importantly, these lesions may be amenable to surgical resection resulting in marked decrease in frequency or even resolution of seizures. MRI is a noninvasive imaging modality without ionizing radiation that has played a central role in the assessment of anatomy, physiology/pathophysiology of children with epilepsy. It is particularly useful in children with refractory focal epilepsy. Prior studies have shown that high resolution, high-field (3T) MR imaging of the brain helps to identify subtle focal epileptogenic abnormalities, including focal cortical dysplasia, in some patients. However, there is scarce data directly comparing the performance of ultra high-field (7T) MRI, currently an investigative technique offering optimized contrast and signal-to-noise rations and superior spatial resolution, with clinically available 3T MR imaging. The purpose of this study is to evaluate whether ultra high-field (7T) MR imaging improves detection and characterization of subtle structural epileptogenic abnormalities in children with focal epilepsy. The importance of this research is that identification of a focal epileptogenic lesion in children with refractory epilepsy has fundamental management implications, as surgical removal of such lesion may dramatically improve outcomes and the chance of seizure freedom.

NCT ID: NCT03154307 Terminated - Epilepsy Clinical Trials

Repeated TMS at Low Frequencies to Reduce Seizure Occurrence

Start date: February 19, 2016
Phase: N/A
Study type: Interventional

Perform non-invasive neuro-navigated repeated Transcranial Magnetic Stimulation (rTMS) at low frequencies (LF) with the intent to reduce the occurrence of seizures over time (long-term protocol). Seizure reduction and improvements in the quality of life in patients with epilepsy will be associated with increased cortical inhibition resulting from the LF-rTMS sessions over time. This procedure using rTMS at low frequencies (LF-rTMS) between 0.5 and 1 Hz is a safe and painless method for noninvasive focal cortical brain stimulation, which will be evaluated in its efficacy at reducing/suppressing seizures. Accordingly, we propose a clinical trial in patients with epilepsy to test whether LF-rTMS can improve seizure suppression. The location of the presumed 3D source in the brain will be stimulated for few minutes (10 to 15 min.). With the same rTMS modality, we will also perform motor threshold mapping in conjunction with its fully integrated and compatible electroencephalography (EEG) module. Up to 100 individuals 18 to 80 years with epilepsy will be enrolled. In addition, a short-term protocol has been added to test whether LF-rTMS can reduce or suppress status epilepticus in medically refractory participants.

NCT ID: NCT03038191 Terminated - Epilepsy Clinical Trials

Epi-collect: Data Collection During Video EEG Monitoring and at Patient's Home

Start date: March 8, 2017
Phase:
Study type: Observational

Epilepsy is a group of neurological disorders characterized by propensity for spontaneous epileptic seizures. Epileptic seizures are the result of excessive and abnormal nerve cell activity in the brain. About 0.7-1% of the world population suffers from seizures. The most common treatment is based on seizure medications that enables about 2/3 of the patients to control their seizures. However, about 20 million patients worldwide, suffer from unpredictable seizures without remedy, and are resistant to medication. In this study EEG and other physiologic signals are collected using wearable sensors, from Epilepsy patients who are at risk of experiencing seizures. The collected signals will be used for developing algorithms that may identify pre-seizure and seizure related periods.

NCT ID: NCT02883712 Terminated - Seizure Clinical Trials

Study of Predictors of Response to Anti Epilepsy in Epilepsy

RESISTANT
Start date: May 21, 2013
Phase:
Study type: Observational

Pharmacoresistant epilepsy remains around 30% despite the development of 25 anti epileptic drugs. Of course, this can be explained by pharmacoresistant epileptic brain diseases, as exemplified by some genetic diseases. However, the lack of specific guidelines for the choice of the anti epileptic drugs (apart from generalized and partial epilepsy) and the very large number of drugs with different and sometimes complex metabolism are challenges for neurologists. Among the 30 % of pharmacoresistant epilepsy, there is a part related to pharmacokinetic drawbacks that could be overcome with a more rigorous approach (i.e. dosage and pharmacogenetics tools). Moreover, the new anti epileptic drugs have metabolism more unrelated with the cytochrome P450 and less generalised adverse events. However, their metabolism could be more complexe (i.e. the less known Uridine 5'-diphospho-glucuronyltransferase (UGT) pathway) and bring more insidious neurological adverse events (i.e. depression, anxiety exacerbation, cognitive disorders worsening) which could largely impede the observance and the quality of life even if the number of seizure is reduced or not. The goal is to determine the predictive and the modulating factors of pharmacoresistance with a global analysis (i.e. whatever the anti epileptic drugs) and with a specific analysis (drug by drug) from a cohort of 1000 patients.
