Filter by:Ictal SPECT with intravenous injection in a cubital vein of a perfusion tracer is an established technique to localize the ictal onset zone during presurgical evaluation of refractory focal epilepsy. When seizures last less than 10 seconds, localizing information is often not obtained. Since it takes around 30 seconds before the tracer reaches the brain after intravenous injection, ictal hyperperfusion most likely has already switched to postictal hypoperfusion. In this study, we plan to inject the perfusion tracer in the aorta proximal to the cerebral arteries, which will allow a true ictal injection in patients with seizures of short duration.
• The goal of this study was to evaluate the safety and efficacy of autologous MSC application for the therapy of drug-resistant symptomatic epilepsy. Adult (18-60 years old) patients (pts) of both sexes suffering from refractory epilepsy with frequent (>5 events per month) seizures were included in this study. The pts were randomized to the standard treatment with anti-epileptic drugs (control group, 30 pts) or anti-epileptic drugs plus autologous mesenchymal stem cells (MSCs) (study group, 30 pts). The pts in the study group received one intravenous injection of ex vivo expanded MSCs (40-101 x 106 cells) and one subsequent endolumbal injection of neuroinduced MSCs (2.7 - 8.0 x 106 cells). Both the unfavorable reactions to MSC infusions and the clinical effects, including complications, were examined. The unfavorable reactions to the MSC injections included local pain or hemorrhage at the site of injection and systemic reactions of the central nervous system (CNS; i.e., hyperthermia, fatigue, and myalgia).The possible beneficial effects of therapy in the two groups of pts were examined based on clinical observations and electroencephalography measurements (prior and 12 months after the application of the MSC-based therapy). To determine potential changes in disease progression, the signs of cognitive impairment, behavioral disorders, and particularly, changes in seizure character and frequency were evaluated using the National Hospital Scale of Seizure Severity. The main points of disease monitoring were "yes" or "no" responses (to therapy), seizure frequency (per month), and remission of disease. Electroencephalography (EEG) recordings were performed to evaluate electrical alpha, beta, theta and delta waves based on standard and additional criteria. The paroxismality index, the peak frequency of EEG activity, the index of slow activity, and the summarized points of EEG pathology signs were calculated for each patient. All assessments were performed for the pts in the control and study groups, and the obtained data were compared to identify the potential differences between the two pts groups. Therapy was terminated when immediate unfavorable reactions to the MSC injections were observed. The final observation of each patient included clinical and EEG assessments at the time point of 12 months (or more) after the application of the MSC-based therapy.
The purpose of this study is to determine the brain cholesterol 24S-hydroxylase (CH24H) enzyme occupancy of TAK-935 after single oral dose in healthy participants using the positron emission tomography (PET) ligand [18F]MNI-792 and PET imaging and to determine the relationship of occupancy to TAK-935 exposure.
This study will assess the effectiveness of the ketogenic diet (high-fat, low-carbohydrate, and moderate protein) in treating epilepsy. Two study groups will be comprised of children with epilepsy (0-18 years of age) and whether or not they receive the ketogenic diet - epilepsy/ketogenic diet and epilepsy/non-ketogenic diet.
This study is to assess the efficacy, safety, and tolerability of the investigational drug UCB0942in adult subjects with drug-resistant focal epilepsy across multiple centers in Europe.
The main objective of this study is to evaluate the feasibility of recording fast-ripples, a potential new biomarker of epilepsy, using the new micro-macroelectrodes developed by Dixi-Medical.
The purpose of this research study is to determine if the blood tests used to measure free thyroid hormone levels are affected by a drug called eslicarbazepine acetate. To determine if eslicarbazepine acetate interferes with these blood tests, blood samples will be analysed so that researchers can compare different types of lab tests that measure these thyroid hormones. Half of the people who participate in this study will already be taking eslicarbazepine acetate either as a study drug or as a prescription (Part 1) and the other half will be people who do not take eslicarbazepine acetate (Part 2).
Previous studies have shown that women on anti-seizure medications are not informed about the pharmaceutical drug interactions between anti-seizure medications (antiepileptic drugs, AEDs) and certain hormonal contraceptive. The goal of this proposed study is to develop and assess the efficacy of an educational handout for participants on the ways AEDs and certain hormonal contraceptives can interact to alter effectiveness of the medications. Reproductive age women (18-45 years old) will be recruited from UCSD Health System Epilepsy clinics. If a patient agrees to participate, she will be given a knowledge exam prior to the clinic appointment to establish baseline understanding of hormonal contraceptive and AED interactions and then the participant will be randomized to receive the intervention (educational handout) or the standard of care (no educational handout). Those in participants in the intervention group will read an educational handout on hormonal contraceptives/AED interactions. Those in the standard care group will not receive this handout and the same knowledge exam will be re-administered to all of the participants after they have completed their appointments to check for knowledge comprehension and short-term knowledge retention. A same-day post-test questionnaire will evaluate participant's intention to discuss hormonal contraceptives/AED interactions with their gynecologist, neurologist or primary care physician.
This is a Phase III, multinational, open-label, non-controlled study with subjects under treatment in the double-blind BIA-2093-311 study (NCT01162460). Subjects will enter the open-label extension study after the preceding double-blind study was unblinded and they are attending their last Extension Phase Visit (EPV) of the double-blind study. For all subjects, the day of the last EPV of the double-blind study will also be the day of Visit 1 for the open-label extension study. All subjects will receive Eslicarbazepine acetate (ESL) under open-label conditions at Visit 1. The complete study duration including treatment with ESL under open-label conditions and follow-up is expected to last approximately 2 years (105 weeks). In case ESL as monotherapy will achieve MA prior to the end of 2017, the study may be discontinued prematurely within 42 days after achievement of MA.
The purpose of this trial is to assess the efficacy, safety and tolerability of lacosamide administered as add-on therapy with 1 to 3 anti-seizure medications. This trial is for children aged 1 month to less than 4 years with epilepsy who currently have uncontrolled partial-onset seizures.
