NCT00113165
This study is being conducted to compare the efficacy and safety of LAMICTAL (lamotrigine) extended-release with placebo in the treatment of partial seizures. LAMICTAL extended-release is an investigational drug. Placebo tablets look like LAMICTAL extended-release tablets but do not contain active medication. In this study, LAMICTAL extended-release or placebo tablets will be added to current seizure treatments.
NCT01462656
A prospective cohort study of antiepileptic drug (AED) polytherapy-treated epilepsy patients within the HealthCore Integrated Research Database (HIRD) will be conducted. Following the launch of Ezogabine (EZG), patients initiating a new AED polytherapy regimen will be followed until the earliest of an episode of urinary retention (UR), change in their AED regimen, end of follow-up, or end of study (when the specified sample size of EZG AED polytherapy users has been attained). After the end of study, the incidence of UR during exposures to EZG and non-EZG AED polytherapies will be compared. Polytherapy will be defined as treatment regimen containing at least two different AEDs. A prospective cohort study of patients who receive EZG under circumstances not indicated in the product label within the HIRD will also be conducted. Following the launch of EZG, epilepsy patients initiating AED monotherapy with EZG as well as non-epilepsy patients initiating EZG for another disease will be followed until the earliest of an episode of UR, change in their AED regimen (if applicable), end of follow-up, or end of study. The incidence of UR during exposure to EZG under circumstances not indicated in the product label will be described. A descriptive analysis of the patients will also be included. To meet the other secondary objective, non-EZG AED monotherapy users will be identified in the prospective cohort and incidence of UR will be calculated to determine if there is a difference in UR risk between monotherapy and polytherapy AED use.
NCT01376180
The purpose of this study is to grasp actual status of usage of lamotrigine tablet and to collect information for using lamotrigine tablet effectively and safely as well as to grasp onset status of adverse events in pediatric subjects, geriatric subjects, pregnant women, subjects with poor renal and hepatic functions.
NCT00203333
People with epilepsy are at a higher risk for sudden unexpected death than the general population. Sudden unexpected death in epilepsy (SUDEP) is a major cause of death in this population, accounting for 10-50% of deaths for those with epilepsy. The risk for SUDEP is particularly high for those with refractory epilepsy. Several lines of evidence support a cardiac mechanism for SUDEP. This study plans to determine: 1. the frequency and types of cardiac arrhythmias that occur in this population and 2. whether these are increased above the general population in the same age group. Additionally, these data will be correlated to specific clinical data, including seizure history, anticonvulsant medications, and any accompanying clinical symptoms.
NCT02378792
Evaluate the long-term clinical effectiveness and safety of the PINS vagus nerve stimulator to patients with refractory epilepsy.
NCT01724918
The purpose of this study is to evaluate the effect of different intravenous doses (IV) of a new anti-epileptic drug (AED) called lacosamide on continuous EEG (electroencephalogram) rhythms (or brain rhythms) in subjects with focal seizures and the tolerability of those doses by patients. In addition, this study will assess the effect of IV lacosamide on EKG (electrocardiogram), a test which checks for problems with the electrical activity of the heart.
NCT00264615
Pharmacokinetic (PK) study to characterize changes in serum concentrations in epilepsy patients when switching from LAMICTAL immediate-release to extended-release and vice versa.
NCT00784212
This study will evaluate the efficacy of BGG492 in reducing the sensitivity to flashing lights of patients with photosensitive epilepsy, using EEG as a readout.
NCT02885207
The knowledge of encephalitis associated with antibodies targeting intracellular antigens, and neuronal surface antibody syndromes has expanded considerably in recent times. The primary purpose of the investigators protocole is to determine the incidence of anti-neuronal antibodies (blood and CSF) in a population of patients suffering from focal epilepsy of unknown cause to guide the management of these patients. The investigators hypothesis is that dysimmune encephalitis is more common than is suggested by the current literature, and that sometimes forms of encephalitis dysimmune "at minimum" can be observed only in the form of focal epilepsy without further manifestation associated.
NCT02876289
Perampanel is a non-competitive antagonist of the AMPA ( 2-amino-3-(5-méthyl-3-hydroxy-1,2-oxazol-4-yl)) propanoïc acid receptors which was approved by the European Medicines Agency as adjunctive treatment for partial-onset seizures in patients 12 years and older, in 2012. The aim of this study is to evaluate effectiveness and safety of perampanel as add-on treatment in patients with refractory epilepsy. The investigators retrospectively collected and analyzed the data of patients with refractory epilepsy who had been treated with perampanel between May of 2014 and April of 2015. In total, one hundred and ten patients were included (mean age 41 \[SD = 15.2\]). The mean duration of epilepsy was 25 years (SD = 14.4). The mean perampanel dose was 5.7 mg/d (SD = 2.3). The retention rate was 77% at 6 months and 61% at 12 months. After 6 months, the responder rate was 35.5%. Eight patients (7.3%) became seizure free. Adverse effects were reported in 60 patients (54.5%). Most common side effects were behaviour disturbance (22.7%), dizziness (15.5%), asthenia (11.8), somnolence (10%) and ataxia (9.1).
NCT01338363
The purpose of this study is 1. To describe patient characteristics and drug usage among children that are prescribed esomeprazole for the first time and to compare them with patients who are prescribed other proton pump inhibitors (PPIs) or H2-receptor antagonists for the first time. 2. To ascertain all incident hospitalized cases of angioneurotic oedema, pneumonia, gastroenteritis, failure to thrive, convulsions/seizures, acute interstitial nephritis and thrombocytopenia among new users in the three cohorts of esomeprazole, other PPIs and H2-receptor antagonists.
NCT02851199
Electroencephalograhy (EEG) is used as a tool for diagnosing epilepsy/convulsions. During the recording, especially for childen who are suspected of having abbcence epilepsy the investigators will perform an EEG recording including a provocation test of hyperventilation in order to induce epileptic discharges. There is no clear instruction about the position of the child during performing this hyperventilation provocation. Clinical observations showed that this provocation is more effective when it's performed in the siiting position. No study was previously performed to investigate this issue
NCT01073579
The purpose of this study is to create a patient registry to collect and analyze information on subjects treated with Sabril and the prescribers of Sabril.
NCT02171195
The purpose of this study is to determine the safety and tolerability of single rising oral doses of BIA 2-093 (proposed doses 20mg, 50mg, 100mg, 200mg, 400mg, 600mg, 900mg and 1200mg) in groups of 8 healthy male adult volunteers.
NCT02799108
Recent data published by various laboratories as well as our preliminary data tend to prove that near-infrared spectroscopy can be used to determine the lateralization of language as part of the preoperative assessment for drug-resistant epilepsy. The reference test used up until very recently was the Wada test, which consisted of injecting an anaesthetic (generally amobarbital sodium) into one of the internal carotid arteries (right or left) in order to determine the predominant cerebral hemisphere for language. This invasive test has been progressively replaced by fMRI, which is nevertheless difficult to perform in children under the age of 7 years. NIRS therefore appears to be a useful alternative, which, in contrast with fMRI, can be easily repeated and allows simple investigation of the various facets of language (e.g. expressive, receptive). In the GRAMFC unit, the investigators have acquired a unique know-how in the field of high-resolution NIRS, both in epilepsy and in the development of language structures.
NCT01278173
The purpose of the study is to evaluate the change in visual fields by means of automated static perimetry and to evaluate the change in retinal structure by means of spectral domain optical coherence tomography (SD-OCT) in adult patients with refractory complex partial seizures (CPS) being treated with vigabatrin (Sabril®)
NCT01284530
Multidose, Open-label, Multi-center Study to examine the steady state pharmacokinetics of TPM XR, as well as, safety and tolerability of repeated oral dosing in pediatric subjects with epilepsy.
NCT00041951
The purpose of our study is to identify gene(s) involved in the cause of childhood absence epilepsy (CAE).
NCT02465047
Background: Epilepsy and nonepileptic attack disorder (NEAD) are chronic conditions that cause many patients to experience a great degree of stress in their everyday lives. Patients have also reported stress as the commonest trigger of their seizures, and animal studies suggest that stress can make seizures worse. A self-help intervention that would help people manage the stress they experience could therefore improve their quality of life and have positive effects on the frequency of their seizures. Research Question: The study evaluates whether a self-help intervention in the form of a brief booklet can improve the quality of life and reduce the levels of stress of people who experience seizures. In addition, the study will explore the associations between seizure severity and frequency, physiological and self-reported stress, and anxiety and depression. Design: The researchers are recruiting patients attending the Outpatient Neurology Clinic at the Royal Hallamshire Hospital and measure their quality of life and stress levels before, one month and two months after they have been given the self-help stress reduction booklet. The researchers will measure the changes in quality of life and stress levels using questionnaires and saliva samples.
NCT02766595
Children referred for routine EEG studies for suspected absence seizures will be asked, upon caregiver's informed consent, to perform 3 minutes of hyperventilation both in the supine position and while sitting up. We aim to demonstrate that hyperventilation is more effective in eliciting absence seizures in a sitting position than while lying down.
