Active clinical trials for "Seizures"

The purpose of this study is to learn more about autism and its subtypes. Autism is a developmental disorder in which children have problems with communication and social skills and display restricted interests and repetitive behaviors. This study has several goals. One aim is to look at types of autism that are known, such as the regressive subtype, (where skills are lost). We will explore whether there is a unique change in immune functioning related to this subtype. Another aim is to serve as one of the sites that will pilot a larger natural history study, entitled Autism Phenome Project. The goal is to further understand autism by identifying other subtypes. We will look at several types of medical issues that may be related to autism, including immunologic problems. Children will be followed over the course of several years. We aim to capture medical problems that may be related to autism as they develop, and study outcomes in areas such as behavior and language, in order to explore known and new subtypes of autism. Normally developing children (aged 1) with autism (age 1, and developmental delays other than autism (age 1), may be eligible for this study. Depending on each child's study group and age, participants may undergo the following tests and procedures: Baseline Visit Medical and developmental history, physical examination, psychological, cognitive and medical tests to assess symptoms of autism or other developmental disorders, photographs of the child's face, collection of hair, urine and baby teeth samples. If available, hair samples from the baby's first haircut and from the biological mother's hair are also collected. Overnight electroencephalogram (EEG): A special cap with electrodes is placed on the child's head to measure brain waves (brain electrical activity) while the child sleeps in the hospital overnight. Healthy volunteers do not undergo this procedure. Magnetic resonance imaging (MRI) scan: The child stays in the scanner, lying still for 10 to 15 minutes at a time. Since it may be difficult for the child to lie still, the test may be scheduled for a time when the child is likely to be sleepy, or the child may be sedated. Lumbar puncture (for children in the autism). This test and the MRI may be done under sedation. Follow-Up Visits Follow-up visits are scheduled at different intervals, depending on study group, age and aspect of the study the child is enrolled in. The visits include a short interview session with the child's caregiver and assessment of the child's development and behavior. Some of the assessment measures used during the baseline examination are repeated, including symptoms ratings, behavioral tests and a blood test. For some children, the final visit will include repeats of the medical procedures.

This is a prospective, observational, exposure-registration and follow-up study of women and their offspring exposed to Keppra® (levetiracetam) and Keppra XR® at the time of conception (i.e., any time from the first day of the last menstrual period) and/or during pregnancy. The UCB AED Pregnancy Registry is designed to monitor pregnancies exposed to Keppra® and Keppra XR® in order to determine if there is a potential increase in the risk of major birth defects compared to rates from women in the general US population. The objectives of the UCB AED Pregnancy Registry are: To prospectively collect data concerning 1) exposure to Keppra® and Keppra XR® during pregnancy, 2) potential confounding factors, 3) outcome of pregnancy, and 4) long-term pediatric outcome To review reported cases of possible birth defects To estimate the risk of birth defects occurring in live-born offspring of women exposed to Keppra® and Keppra XR® during pregnancy This study is being conducted in the United States (US). Enrollment in the Registry is voluntary. The UCB AED Pregnancy Registry is sponsored by UCB, Inc. and is managed by INC Research. The scientific conduct and analysis of the Registry is overseen by an Expert Panel consisting of external specialists in teratology/genetics, epidemiology, maternal and fetal medicine, and neurology (external member details available upon request).

Researchers are interested in studying if magnetic resonance imaging (MRI) is practical for locating the areas of the brain associated with language in children with epilepsy. When a region of the brain is active, it uses more fuel in the form of oxygen and sugar (glucose). As the brain uses more fuel it produces more waste products, carbon dioxide and water. Blood carries fuel to the brain and waste products away from the brain. As brain activity increases blood flow to and from the area of activity increases also. Patients participating in the study will be asked to perform tasks designed to test language skills while undergoing an MRI to detect areas of the brain using oxygen and receiving blood flow.

The purpose of the study is to develop an emergency electroencephalogram (EEG) device, StatNet, that can be placed quickly by minimally-trained personnel and interpreted remotely for rapid identification of seizures.

The purpose of this proposed research is to identify individuals in southeastern Arizona aged 65 years and older who have new onset seizures (or newly diagnosed epilepsy) and monitor them for at least two years. In doing so the investigators will be able to describe the public health burden of this condition and to identify factors that predict clinical outcomes and health care needs in this population, using quantitative, administrative, and qualitative data. The aims of this proposed research are 1) to determine the two-year incidence of newly diagnosed epilepsy in the target population, 2) describe health care resource utilization of the target population using Medicare data, 3) validate the use of Medicare beneficiary data to estimate incidence of epilepsy, and 4) describe the burden of this condition in different ethnic groups.

Pediatric patients are admitted to the emergency room for diverse causes, beside trauma, patients can present with convulsions, suspicion of brain tumor or increased intracranial pressure. In most of the cases a brain CT is performed even before physical examination by a skilled neurologist. The amount of radiation that the children are exposed is equivalent to 100 plain chest X rays. The purpose of this tudy is to examinate in a retrospective study what were the indications for CT study and what was the incidence of relevant abnormal findings that required emergency intervention or referral.

Children with seizure disorder face unique challenges during the perioperative period. Fasting, sleep-deprivation, and missed doses of medications while patients are required to have nothing per mouth (NPO) are a few factors that decrease the seizure threshold. The incidence of seizures in this population is unknown but correlated with patient's underlying condition and missed doses of anti-convulsant. Previous work has determined this is not a unique problem. The investigators initially found compliance extremely poor at 60%. The investigators have made improvement to about 80% compliance through various interventions: education of nursing, availability of anticonvulsant intravenous dosing alternatives, and re-wording the hospital NPO policy. The investigators feel that a new, more focused, survey will help identify, perioperative reasons for non-compliance on part of the parents. This information will be utilized to guide further interventions aimed at improving compliance.

In many fields of medicine, except seizure disorders, blood biomarkers have captured an integrated part of diagnostic decision making, including copeptin, the surrogate marker of vasopressin release. There are strong arguments to hypothesize circulating copeptin is elevated in epilepsy, especially in generalized seizures such as fever seizures (FS), and that copeptin is predictive for complexity and relapse at least in FS. Although long-term morbidity and mortality are both low in FS, there is high anxiety among parents because of a lack of criterions to identify children at risk for relapse. Copeptin may fill this gap by adding important diagnostic and prognostic information. Eventually, less children may receive needlessly over years fever drugs or anti-epileptic drugs.

The Extended Access Program (EAP) is a managed access programme for Perampanel. The main objective of this EAP is to ensure that patients participating in studies E2007-A001-207, E2007-G000-307, or E2007-G000-235 continue to have access to perampanel until such time perampanel tablets become commercially available for the treatment of Partial Onset Seizures (POS) in the country in which they reside. This EAP will consist of 2 phases: Screening: The patient will start the program once the Screening assessments are completed and the patient is qualified for participation. Treatment: Additional assessments, physical examinations, and dosage changes will be clinically determined by the treating physician. Patients will enter this program on the same dose of perampanel that they were receiving at the end of their participation in previous study. Doses of perampanel and of concomitant anti-epileptic drugs (AEDs) can be adjusted (i.e., added,removed, or changed in dose) based on clinical judgment. Treatment will be prescribed as long as clinically appropriate according to the judgement of the treating physician and the approved Summary of Product Characteristics (SmPC). The program will complete in a staggered fashion, country by country, as and when perampanel becomes commercially available for the treatment of POS in each country.
