Carbon Dioxide (CO2) Chemosensitivity and SUDEP
EpilepsySUDEPThe purpose of this research study is to better understand what causes Sudden Unexpected Death in Epilepsy (SUDEP). This study will enroll subjects from the University of Iowa Hospitals and Clinics (UIHC) Epilepsy Monitoring Unit (EMU) and Epilepsy Clinics. The investigators will analyze the effects of seizures on breathing, on the cardiovascular system, and on arousal. The investigators are studying these effects because some cases of SUDEP might be due, in part, to an inability to wake up or sense elevated carbon dioxide (CO2) levels when breathing is impaired. Subjects will be followed for ten years after enrollment to monitor their health.
Risk Factors for Sudden Unexplained Death in Epilepsy
SUDEPThe main purpose of this study is to develop a North American registry for SUDEP cases; requesting family members of epilepsy patients who died suddenly of unclear causes (SUDEP) to contact the study team. The family members who decide to participate in the study will be asked to complete a brief telephone interview about their loved one's epilepsy and seizure history and the circumstances of his or her death. If the death has occurred within the past 24 hours, and the family is willing to consider donating tissue to the study, the subject will be transferred to the Autism Tissue Program, and the remainder of the phone interview will be conducted at a later time. In addition to the phone interview, the family will be asked to provide access to the deceased's medical records. Any costs involved in obtaining medical records will be covered by the study, and all medical information will remain completely confidential.
Genetic Markers of Cardiovascular Disease in Epilepsy
EpilepsySeizures3 moreEpilepsy 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.
Electroclinical Features of Sudden Unexpected Death in Epilepsy (SUDEP) : a Multi-center Observational...
Sudden Unexpected Death in EpilepsyNear-Sudden Unexpected Death in EpilepsySudden unexpected death in epilepsy (SUDEP) is regarded as a leading cause of premature death in epilepsy patients. We aim to capture the whole process of SUDEP and near-SUDEP occurrence in patients with epilepsy, and expolre video-electroencephalograph (V-EEG) changes and marker. A Chinese multicenter study was carried out to determine electroencephalo-graph marker related to SUDEP to provide a scientific basis for the prevention of SUDEP in patients with epilepsy.
Improving Patient Communication About SUDEP
SUDEPEpilepsyChildren with generalized tonic-clonic seizures (GTCS) have about a 1 in 4500 of succumbing to sudden unexpected death in epilepsy (SUDEP). For that reason, the American Academy of Neurology recommends that clinicians caring for these children make their families aware of this small but important risk and provide appropriate supportive follow-up resources. Moreover, existing evidence suggests that children with poorly controlled GTCS have a strikingly increased odds of SUDEP, 3-24 fold, raising the importance of improving seizure control. Clinicians caring for these patients have multiple issues to address in the typical visit. The investigators propose to use information technology to help providers assure that addressing SUDEP is incorporated into their routine care. The investigators have developed the Child Health Improvement through Computer Automation system (CHICA), a computer based clinical decision support system for pediatric care. CHICA captures patient reported data in the waiting room and prioritizes clinical advice to the physician through the electronic health record (EHR). CHICA is used in five primary care clinics in the Eskenazi health system where it supports general pediatric care. The goal of this project is to test the effectiveness of a SUDEP module in this setting where CHICA is already in use - with a future goal of developing a full suite of CHICA modules for child neurologists.
Serotoninergic Pathways in Sudden and Unexpted Death in Epilepsy (SUDEP)
Sudden Unexpected Death in Epilepsy (SUDEP)The mortality rate is increased in patients with epilepsy, and especially among patients with drug-resistant epilepsy. This increased mortality is mainly related to the risk of SUDEP whose incidence is between 3.5 and 9 per 1,000 for patients with drug-resistant epilepsy. The term SUDEP refers to a sudden death occurring in a patient with epilepsy in whom anamnestic and post-mortem evidence does not identify a particular cause. Experimental and clinical data strongly suggest that most of SUDEP result from a postictal respiratory dysfunction progressing to terminal apnea. Due to the major role of serotonin in regulating breathing rhythms and data in animal models of epilepsy, it is envisaged that an alteration of serotonergic systems of the brainstem and limbic regions may play a central role in the occurrence of SUDEP. The objective of this work is to look for abnormalities of the serotonergic transmission within regulatory regions of respiratory and autonomic functions in brain samples prospectively collected in patients died from SUDEP.
