Active clinical trials for "Epilepsy"

Epilepsy is a common health problem worldwide. In general population, studies in developed countries estimated the annual incidence of epilepsy to be~50 per 100,000 and prevalence to be ~8.2 per 1,000. These figures are higher in developing countries in which prevalence of >10 per 1,000 was reported. In Upper Egypt, Assiut Governorate, the prevalence rate was 12.9 per 1,000. In people with epilepsy there is an associated high rate of cognitive difficulties that compromise educational progress and achievement throughout life. Approximately 1-5% of the population exhibits epileptiform discharges on electroencephalography (EEG). Interictal epileptiform discharges (IEDs), meaning spikes, polyspikes, sharp waves, or spike and slow-wave complexes without observed clinical seizures, are commonly observed in patients with epilepsy. Epilepsy syndromes manifesting with IEDs are detrimental to cognitive function. Recently, two studies found that frequent IEDs can impair cognitive performance in children. and adult patients. Several studies indicated that IEDs in patients with epilepsy had a disruptive effect on information processing speed with even a low percentage of IEDs (1%).However, it is unclear whether IEDs are associated with disrupted academic performance in patients with idiopathic epilepsy, and the relationship between general cognitive ability and academic performance in those patients has not been clarified. Understanding how IEDs interfere with neurocognitive outcomes is important ,while the goal of medical and surgical treatments for epilepsy is to achieve seizure-freedom with minimal morbidity, the benefits of IED suppression are more controversial.

This is an observational study to confirm the non-inferior effectiveness on health outcomes of tele-counseling or tele-prescription, which was the first outpatient system applied to the actual medical sites in Korea during the coronavirus disease 2019 (COVID-19) pandemic. Researchers collect data using electronic medical records and questionnaires to patients and their caregivers who are continuously receiving outpatient treatment for epilepsy at a single center. The results of the study will be presented by comparing the health outcomes between the non-face-to-face care group and the usual care group.

Levetiracetam is a widely prescribed antiseizure medication in epileptic children due to an estimated better safety profile and easy accessibility. There is limited and contradicting data about the effect of levetiracetam on serum lipid metabolisms, especially in epileptic children. The aim of our study was to evaluate the effect of levetiracetam therapy on lipid metabolism in euthyroid non-obese epileptic children. In this case-control study, the investigators recruited 37 epileptic children receiving levetiracetam monotherapy for at least 12 months and 54 healthy controls. All the participants were euthyroid and within normal nutritional status limits for their age. Fasting blood samples were obtained for serum thyroid-stimulating hormone (TSH), free triiodothyronine, free thyroxine, total cholesterol (TC), high-density lipoprotein (HDL), low-density lipoprotein (LDL), triglycerides, Triglyceride/HDL Index, uric acid, CRP, and transaminases at the administration. The investigators would like to show if epileptic children with levetiracetam monotherapy are susceptible to lipid metabolism alterations.

Advance in stroke treatment have resulted in a dramatic reduction in the stroke mortality, however, the number of stroke survivors living with morbidity has increased significantly. As we know, post-stroke epilepsy has been identified as a significant clinical issue in stroke survivors and stroke is the most common cause of epilepsy in older adults and for patients aged more than 65, post-stroke epilepsy accounts for 30-50% of new-onset seizures. Our previous study documented seizures during stroke presentation and during hospitalization would worsen the overall morbidity and mortality, suggesting the importance of awareness in seizure care in acute ischemic stroke. As current studies only focus on anti-seizure/anti-convulsion after the appearance of late-onset seizures, without the intervention of the epileptogenesis, it is important to develop a potential novel prophylactic treatment on patients with acute severe stroke to prevent from late occurrence of seizures and epilepsy. We have previously done researches on the medications that might have potential of anti-epileptogenesis in pilocarpine-induced animal models, supporting the concept of antiepileptogenesis, giving intervention immediately following a brain insult. The results of some earlier anecdotal reports or small studies on prophylactic use of antiepileptic drug (AED) therapy in stroke, either hemorrhagic or ischemic strokes, remain inconclusive. There still lacks a well-established case-control study on prophylaxis of post-stroke epilepsy, with the early intervention of AED therapy with potential of anti-epileptogenesis in the phase of epileptogenesis. Based on our clinical experience, and laboratory researches, we have noted two non-conventional AEDs, levetiracetam (LEV) and perampanel (PER) with potential of anti-epileptogenesis. It is justified to evaluate if early administration of LEV or PER in patients with acute major stroke as a prophylactic therapy could hamper the development of epileptogenesis and the later post-stroke epilepsy. We aim to conduct a randomized case-control study to evaluate if early prophylactic introduction of low dose AED therapy (LEV or PER) in patients with moderate to severe middle cerebral artery infarct, could prevent the development of post-stroke epilepsy (primary prevention).

Researchers are trying to incorporate a process known as Functional MRI (fMRI) scanning to reveal a pattern in brain activity during Deep Brain Stimulation (DBS), which will correlate to possible seizure freedom.

The purpose of this research is to find out how people with epilepsy and possible symptoms of anxiety or depression are doing for 6 months after a regular epilepsy clinic visit. Participants in this study will complete questionnaires either by phone or via the patient portal.

Lacosamide is an antiepileptic drug approved for using like adjuvant treatment in adults epileptic crisis. Previous studies has granted to the adjuvant therapy a significant efficacy. This is an observational study, multicenter and retrospective, in patients with epilepsy. The aim of study is the evaluation of the adjuvant treatment with Lacosamide administered over 12 months. The investigators will collect information from 860 patients in 13 spanish centers. The secondary aim is assess the tolerability of treatment during 3,6 and 12 month.

Vagus Nerve Stimulation (VNS) Therapy has been approved marked for the treatment of epilepsy since 1994. This post-market study is designed to follow the clinical course and outcomes for patients with refractory seizures treated with adjunctive VNS Therapy. Seizure frequency, seizure severity, side effects burden, depressive symptoms, global impressions, and health care utilization will be evaluated. The results of this study will provide data to guide physicians and their patients in the use of VNS Therapy for patients with refractory seizures who have failed initial trials of anti-epileptic drug (AED) therapy. The data being collected is not for the purposes of confirmatory assessment.

The purpose of this study is to determine the effect of lacosamide on mood and quality of life in people with epilepsy.

The objective of this study was to confirm if two formulations of gabapentin (capsules) are bioequivalent. Test product was Darbetin® 300 mg (Laboratorios Dermatológicos Darier) and reference product Nerotin® 300 mg (Pfizer). One capsule was the single dosage. The study was prospective, open-label, randomized, crossover, single dose, with 02 treatments, 02 sequences and 02 periods, under fasting conditions. The population was composed of 26 healthy volunteers, both genders, adults between 18-55 years. The comparative bioavailability of the two formulations was evaluated based in statistical comparisons of relevant pharmacokinetic parameters, obtained from data of drug concentrations in blood.
