Active clinical trials for "Seizures"

Bronchiolitis is the leading cause of pediatric intensive care unit admission in infants. Seizures during bronchiolitis may be a neurological complication of respiratory viruses but also of the treatments. The investigating team's hypothesis is that the incidence of seizures is not so so uncommon in infants hospitalized in the pediatric intensive care unit for severe bronchiolitis.

This retrospective observational cohort study is to assess and analyze clinical, electroencephalographic, laboratory, comorbidity, and treatment characteristics of Intensive care unit (ICU)-patients with epileptic seizures and to subsequently compare their characteristics with ICU-patients with status epilepticus (SE).

An algorithm has been developed for simplified classification of epileptic seizures, in order to optimize choice of antiepileptic drugs. The objective of this study was to clinically validate the algorithm.

This is a phase III, pilot, prospective study of an Electromyography (EMG) based seizure detection system for detecting Generalized Tonic-Clonic Seizures (GTCS) in the home.

This is a Non-interventional Prospective Study. Centres will enroll adult patients with partial onset seizures for whom the clinician has decided to initiate ZNS as an adjunctive therapy prior to the decision to take part in this study. Patients to be enrolled into the study are not sufficiently controlled with one dug licensed for the use of monotherapy in partial onset seizures. Patients will be seen at baseline and then during normal clinical visits at intervals which are appropriate to the typical practice of the treating clinician. Patients will be assessed at baseline and then at least 3 and 6 months after the baseline.

Characterization of the cardiac response (ECG) preceding an epileptic seizure.

The landmark study Diabetes Control and Complication Trial (DCCT) clearly showed that intensive insulin management delays the onset and progression of longterm complications in adolescents with type 1 diabetes mellitus (T1DM). The same clinic trial also showed increased rate of severe hypoglycemia which required assistance. The risks of severe hypoglycemia, defined as loss of consciousness or seizure associated with hypoglycemia, include lower HbA1C, younger age, higher insulin dose, male sex, lower parental socioeconomic status, non-Hispanic white ethnicity, longer duration of disease, the presence of psychiatric disorders, and underinsurance. The purpose of this protocol is to explore the relationship between hypoglycemic seizures and BMI.

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.

This study will evaluate the magnetoencephalography (MEG) alone and together with electroencephalography (EEG) in non-invasive presurgical evaluation. It will look at the contribution of those methods in determining the location of the epilepsy seizure, compared with doing so through an invasive method. EEG measures electronic potential differences on the scalp. On the other hand, MEG is a non-invasive technique for recording the activity of neurons in the brain, through recording of magnetic fields caused by synchronized neural currents. It has the ability to detect seizures. Because magnetic signals of the brain vary, this technique must balance two key problems: weakness of the signal and strength of the noise. The EEG is sensitive to extra-cellular volume currents, whereas the MEG primarily registers intra-cellular currents. Because electrical fields are quite dependent on the conductive properties of the tissues, and magnetic fields are significantly less distorted by tissue, the MEG has better spatial resolution. There is a great deal of evidence that EEG and MEG provide complementary data about underlying currents of ions. Patients 18 years of age or older who have epilepsy that is not relieved, and who are considered candidates for surgery and who accept epilepsy surgery, may be eligible for this study. Before they have surgery, participants will either sit or lie down, with their head in a helmet covering the entire head, with openings for the eyes and ears. Brain magnetic fields will be recorded with a 275-channel OMEGA system. Throughout the session, visual and two-way audio communication will be maintained with the patient. Acquiring data from the participant will be conducted during several sessions, each lasting from 10 to 60 minutes, not exceeding a total of 120 minutes. If the first recording is not of sufficient quality, the patient may have it repeated once or twice. Those participants who are found to have a clear seizure focus will proceed directly to surgery that is part of their treatment. Those whose seizure focus is ambiguous will proceed to invasive monitoring. Participants will be followed in the outpatient clinic at intervals of 1, 3, 6, and 12 months. They may periodically undergo reimaging as considered appropriate.

This study will explore how the mind and the brain work to cause movement symptoms or seizures in people who do not have a recognized neurological or medical disorder. The study includes a check for psychiatric disorders, symptoms and their severity; psychiatric and personality questionnaires; and neuropsychological testing. Normal, healthy volunteers, people who have movement symptoms not due to a brain or medical disorder and people who have seizures not due to epilepsy may be eligible for this study. All candidates must be 18 years of age or older. All participants have a medical history, physical examination and psychological evaluation, including completion of questionnaires. People with movement symptoms or seizures have a symptoms evaluation. Some participants also undergo neuropsychological testing, including questionnaires, pen-and-paper or computerized tests, and motor tasks.
