Active clinical trials for "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.

This study will allow researchers to use various types of tests to evaluate cognitive and sensory functions. These tests, referred to as "batteries" will evaluate attention, executive functions, general intellectual functioning, language, memory, motor functions, orientation, personality, selected sensory and perceptual functions, vigilance (alertness), and visual-spatial functions. Children and adult patient will receive different test batteries. The goals of this research study are to; Create descriptions based on the performance of each patient on the test batteries. Then use this information to relate patient behavior to their neurophysiological, neuroradiological, and biochemical descriptions. Define subgroups of patients based on their neurobehavior in order to decrease the variability of psychiatric diagnoses, treatments, and prognoses.

Currently, hypothetical models of understanding Psychogenic Non-epileptic Seizures (PNES) involve emotional dysregulation. The hypothesis of a disorder of emotional experience is mainly based on behavioral data and disturbance of autonomic responses in response to images in emotional content (Mignot et al 2015, in submission; Bakvis et al 2013). Various imaging studies have identified brain structures belonging to the limbic system in particular that seem functionally impaired in this population. These functional connectivity abnormalities are correlated with dissociation scores in PNES patients (Van der Kruijs et al 2012 and 2014). Investigators propose to specifically study the brain activity of PNES patients during tasks emotional content to identify the mechanisms involved in this emotional dysregulation. This work is essential to understanding the mechanisms and the development of new therapeutic strategies

The occurrence of isolated or recurring epileptic seizures accounts for an important use of the healthcare system. Typically, epileptic patient will consult ten times a year a physician (specialist or familial doctor) and will justify 24 diagnostic procedures or additional examinations. Moreover, epileptic seizures are associated with frequent use of emergency departments. From the first emergency call received by the Emergency medical assistance service (SAMU), the actual management of the patient having epileptic seizure includes the eventual transfer to the paramedical team then within an emergency unit. However in some cases, emergency allocation may be avoided as 70% of patients recover their baseline condition upon admission. The main objective of this study is to describe the management of the adult population suffering from suspected seizure by the emergency structures. For 3 consecutive days, all patients with suspected epileptic seizures (diagnosed by the SAMU, paramedics and emergency unit) will be enrolled in the study. Data of medical care management and information from patients or witnesses will be collected on a questionnaire by the physicians of the SAMU, paramedics and emergency unit. Then, the anonymized questionnaires will be sent to RESUVAL (Emergency Network of the Rhone Valley) to ensure data entry and statistical analysis. By identifying the factors leading the SAMU to transfer a patient with suspected epileptic seizure to an emergency unit, this study will provide a more appropriate procedure to prevent unnecessary emergency admissions. It will also gain more insights into the patient outcomes, such as complementary medication, brain examination or referral to a neurologist.

The purpose of this trial is to evaluate the efficacy, safety, and pharmaco-economics of Lacosamide Tablet as first add-on therapy for uncontrolled focal onset epilepsy ,invetigating effects of lacosamide Tablet on cognitive function of children and anxiety and depression of adults with focal onset seizures In real-world clinical setting

The incidence of provoked and unprovoked seizures is known to increase with advancing age. Eslicarbazepine acetate (ESL) is one of the third generation of antiepileptic drugs (AEDs) that have been developed in the last ten years with a favorable safety profile. ESL is approved in Europe and the USA as adjunctive or monotherapy in adults with partial-onset seizures. Nevertheless, retrospective data in monotherapy condition in the elderly epileptic population are sparse. The aim of the ZEBRE study is to evaluate the efficacy and the safety of ESL in elderly epileptic patients (> 65 years). The completion of this study will provide crucial information on the most appropriate ESL treatment for elderly patients suffering from partial seizures.

Epilepsy, defined as recurrent, unprovoked seizures, is a common condition, affecting 0.5-1% of the general population. People with uncontrolled epilepsy suffer poor health and increased mortality due to their condition. They frequently experience social stigma and are socioeconomically disadvantaged. It is therefore imperative to help them gain control of their seizures as quickly as possible. A wide range of antiepileptic drugs (AEDs) has become available to treat people with epilepsy. However, despite maximal therapy, approximately 20-40% show pharmacoresistance (PR) and thus continue to have seizures. We do not understand why a significant proportion of people with epilepsy have PR. For any given patient presenting with a first unprovoked seizure, we are unable to predict PR at the time of presentation. At least 2 different AEDs must be tried at maximum doses for a year before we can diagnose PR. At this point, surgical therapies become an increasingly urgent consideration. Retrospective magnetic resonance imaging (MRI) studies in the chronic stages of epilepsy have shown that patients with PR are more likely to have focal structural lesions in the brain, and in particular to have signs of damage to the hippocampi. For example, there are retrospective data suggesting that a decreased hippocampal N-acetylaspartate (NAA)/creatine ratio (measured by magnetic resonance spectroscopy [MRS]) and hippocampal atrophy (determined by hippocampal volumetry) correlate with PR. However, it is not clear whether these findings reflect the underlying pathophysiology of PR, or simply reflect the effects of chronic seizures and chronic drug treatment on the brain. The First Seizure Clinic at the Halifax Infirmary represents a unique opportunity for prospective, longitudinal studies of patients who present with a first seizure or with newly diagnosed epilepsy. In these patients, advanced neuroimaging techniques at presentation might show changes that truly reflect the underlying pathophysiology of PR, rather than changes that develop as a consequence of prolonged seizures and drug treatment. Neuroimaging follow-up might help us to understand the pathophysiologic changes that accompany the evolution of PR. Ultimately, it is our hope to combine neuroimaging features and clinical features of patients with PR in a predictive model that would help us to predict PR at presentation.

The study utilizes microEEG (a novel miniaturized, FDA approved EEG device) to prospectively investigate the cerebral electrical activity of infants with Apnea, Bradycardia and Desaturation events. This project will also assess the feasibility of using the microEEG device in the Neonatal Intensive Care Unit (NICU) setting and the feasibility of remote centralized interpretation in this setting.

The ANSeR Clinical Investigation is a multi-centre, randomised, controlled, clinical investigation of a standalone decision support Algorithm for Neonatal Seizure Recognition, the ANSER Software system.
