Filter by:Epilepsy is a common condition which affects over 3 million people in the US. Patients with uncontrolled epilepsy have a lifetime risk of sudden unexpected death (SUDEP) of 35%, which is greatest in those under 40 years of age. The exact mechanisms and causes are not understood but can be due to underlying conditions which affect the heart and brain, which may lead to dangerous heart rhythms and death. Some of these conditions which affect heart and brain have an identifiable genetic cause. This study aims to identify known genetic causes of heart rhythm and sudden death related disorders in patients with epilepsy.
A Multicentre, observational and cohort study to get the incidence of new-onset or newly-diagnosed seizure in neonatal population. EEG will used to record the change of brain electric activity and diagnose. Other data also will be collected since first seizure until confirmed diagnosis.
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 goal of this study is to evaluate effectiveness of the phone follow-up method compared to the conventional filler taken one.
Approximately a fourth of children with seizures do not respond adequately to available therapy. Ketogenic therapy has a long history as treatment for intractable epilepsy, but there is no agreement concerning how it works and what is the best way to administer it. This natural history study will collect data pertaining to both questions.
Febrile seizures occur in 2-5% of the population and are typically limited to children between 3 months and 5 years-of-age. The pathophysiological link between increased body temperature and increased seizure susceptibility is unsolved in humans. In a mouse model it has been shown that young animals had a tendency to hyperventilate thereby causing intra-cerebral hypocapnia / alkalosis and a decrease of their seizure threshold. This effect was not observed in older animals. Redressing the pCO2 (carbon dioxide partial pressure) by breathing carbon dioxide enriched air instantly stopped the seizures. In this study the investigators want to investigate the respiratory physiology in children with febrile seizures and compare it to children who have fever but did not have febrile seizures. The investigators hypothesize that in children with febrile seizures the rising body temperature triggers a larger increase of respiratory rate (hyperventilation) and subsequent drop in pCO2 levels. This study could provide the basic physiological data for an interventional trial to test the efficacy of carbon dioxide inhalation to interrupt febrile seizures.
Investigators at Boston Children's Hospital are conducting research in order to better understand the genetic factors which may contribute to epilepsy and related disorders. These findings may help explain the broad spectrum of clinical characteristics and outcomes seen in people with epilepsy.
Epilepsy is a chronic neurologic disorder characterized by seizures. Beside seizures people suffering from epilepsy experience several challenges related to education, work and everyday life such as learning-, problem-solving-, memory-, concentration-, attention difficulties and fatigue. It is generally approved that physical activity (PA) has a positive effect on physical as well as mental factors. However, people with epilepsy are found to be less active and PA is rarely offered or recommended as supplement to anti-epileptic medical treatment. Few studies have investigated the effect of PA in subjects with epilepsy and additional studies of high methodical quality are needed to enable evidence-based information and counselling. This study is carried through as a randomized controlled trial which investigates the effect of participation in a 10-week cardio exercise program in people with Juvenile Myoclonic Epilepsy aged 15-50. The study hypothesis is that participation in a 10-week cardio exercise program will induce a positive change in cognitive function (concentration and attention) and possibly in brain-derived neurotrophic factor (BDNF). In addition it is expected that the intensity and duration of the 10-week cardio exercise program is sufficient to cause changes in physiological parameters related to a reduced risk of lifestyle diseases.
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.
With the use of molecular methods new viruses have been detected in respiratory and gastrointestinal tracts of both patients and asymptomatic subjects in recent years. The clinical importance of these viruses has not been adequately studied. The aim of this study is to use molecular methods to detect viruses in upper respiratory tract and gastrointestinal tract of children with acute bronchiolitis, acute gastroenteritis and febrile convulsions and to try to correlate the severity of clinical picture with the amount of viruses present in clinical samples. The investigators will also try to detect the increase in specific antibodies in paired sera.
