Sudden unexpected death in epilepsy (SUDEP) is a nontraumatic, nondrowning death of an individual with epilepsy in which an autopsy with appropriate ancillary studies does not identify a cause of death. The mechanism of death in SUDEP is unknown, but is thought to involve cardiac and/or respiratory mechanisms. Research in SUDEP is hindered by a lack of consensus regarding required components of a death investigation before a cause of death may be certified as SUDEP. Histopathologic examination of the cardiac conduction system is not routinely performed in SUDEP death investigations...

Loeys-Dietz syndrome is a recently described autosomal dominant disorder with underlying vasculopathy characterized by aortic and other vascular aneurysmal dissection/rupture. A 61-year-old man is reported who died suddenly and unexpectedly and at autopsy was found to have a ruptured abdominal aortic aneurysm. Additional findings included dolichostenomelia, high-arched palate, and pectus excavatum. There was a strong family history of Loeys-Dietz syndrome, although the decedent had never been tested. Death was, therefore, due to a ruptured abdominal aortic aneurysm in a case of probable Loeys-Dietz syndrome...

Knowledge gaps persist about the incidence of and risk factors for sudden death in the young (SDY). The SDY Case Registry is a collaborative effort between the National Institutes of Health, the Centers for Disease Control and Prevention, and the Michigan Public Health Institute. Its goals are to: (1) describe the incidence of SDY in the United States by using population-based surveillance; (2) compile data from SDY cases to create a resource of information and DNA samples for research; (3) encourage standardized approaches to investigation, autopsy, and categorization of SDY cases; (4) develop partnerships between local, state, and federal stakeholders toward a common goal of understanding and preventing SDY; and (5) support families who have lost loved ones to SDY by providing resources on bereavement and medical evaluation of surviving family members...

Symptoms of temporal lobe epilepsy (TLE) are frequently associated with autonomic dysregulation, whose underlying biological processes are thought to strongly contribute to sudden unexpected death in epilepsy (SUDEP). While abnormal cardiovascular patterns commonly occur during ictal events, putative patterns of autonomic cardiac effects during pre-ictal (PRE) periods (i.e. periods preceding seizures) are still unknown. In this study, we investigated TLE-related heart rate variability (HRV) through instantaneous, nonlinear estimates of cardiovascular oscillations during inter-ictal (INT) and PRE periods...

This review aims to empower general neurologists to provide better informed person-centred advice on sudden unexpected death in epilepsy (SUDEP) to people with epilepsy in order to help keep them safe. Past and present evidence is consolidated in order to inform readers about SUDEP, and up-to-date insights into the epidemiology, diagnostic classification, pathophysiology, risk factors, influence of co-morbidity, and importance of sensitive person-centred communication are outlined. This review provides "fingertip" information to the practicing neurologist with regards to identifying and communicating risks for SUDEP and suggests practical measures for managing these risks in partnership with the patient...

Febrile seizures are usually considered relatively benign. Although some cases of sudden unexplained death in childhood have a history of febrile seizures, no documented case of febrile seizure-induced death has been reported. Here, we describe a child with complex febrile seizures who died suddenly and unexpectedly after a suspected seizure while in bed at night during the beginning phases of sleep. She was resuscitated and pronounced brain dead 2 days later at our regional medical center. Autopsy revealed multiorgan effects of hypoperfusion and did not reveal an underlying (precipitating) disease, injury, or toxicological cause of death...

Sudden unexpected death in epilepsy (SUDEP) is a major cause of death in patients with refractory epilepsy, particularly those with chronic epilepsy. The physiopathological mechanisms underlying SUDEP have not been elucidated. Autonomic dysregulation of cardiac or respiratory function is thought to underlie SUDEP. Here, we present a summary of available evidence on the involvement of the insular lobe in the regulation of cardiorespiratory function. Ictal discharge that originates in the cortex can, primarily or secondarily, involve the insula lobe through epileptogenic signal networks, leading to cardiorespiratory dysfunction, central apnoea, arrhythmias, and sudden death in patients with epilepsy...

Patients with early infantile epileptic encephalopathy (EIEE) experience severe seizures and cognitive impairment and are at increased risk for sudden unexpected death in epilepsy (SUDEP). EIEE13 [Online Mendelian Inheritance in Man (OMIM) # 614558] is caused by de novo missense mutations in the voltage-gated sodium channel gene SCN8A Here, we investigated the neuronal phenotype of a mouse model expressing the gain-of-function SCN8A patient mutation, p.Asn1768Asp (Nav1.6-N1768D). Our results revealed regional and neuronal subtype specificity in the effects of the N1768D mutation...

The incidence of out-of-hospital sudden unexpected death (OHSUD) in a racially and socioeconomically diverse population has been inadequately studied. We collated all OHSUDs over a 24-month period among 18- to 64-year olds in Wake County, North Carolina, to investigate geographic and socioeconomic disparity in incidence of OHSUD. An electronic query of Wake County Emergency Medical Services (EMS) identified all EMS attended out-of-hospital deaths. After excluding trauma, expected deaths, and deaths occurring in non-free-living subjects, medical records and medical examiner's reports were reviewed by a committee of cardiologists to make the determination of OHSUD...

BACKGROUND: In many countries there are now detailed Child Death Review (CDR) processes following unexpected child deaths. CDR can lead to a fuller understanding of the causes for each child's death but this potentially intrusive process may increase the distress of bereaved families. In England, a joint agency approach (JAA) is used where police, healthcare and social services investigate sudden child deaths together and a key part of this is the joint home visit (JHV) where specialist police and paediatricians visit the home with the parents to view the scene of death...

Deaths occurring at home are increasing in the United States. Primary care physicians and trainees may not be explicitly taught about management of deaths in the home. Physician responsibilities for expected and unexpected deaths at home are summarized. The medical examiner should be contacted if death was due to natural disease processes but occurred suddenly or when a physician was not treating the decedent. Police and emergency personnel are often called after terminally ill individuals have died at home, which may cause significant family distress and is typically not necessary if the death was expected...

OBJECTIVE: The aims of the review are to establish the number of undiagnosed neoplasms presenting at autopsy in a single centre and to determine the incidence and most common causes of sudden unexpected death due to neoplasia in infancy and childhood (SUDNIC). DESIGN: Retrospective observational study of paediatric autopsies performed on behalf of Her Majesty's Coroner over a 20-year period (1996-2015; n = 2,432). Neoplasms first diagnosed at autopsy were identified from an established database and cases meeting the criteria for sudden unexpected death were further categorised...

We investigated the causes of inpatient death after intensive care unit (ICU) discharge and determined predictors of in-hospital mortality in Korea. Using medical ICU registry data of Seoul National University Hospital, we performed a retrospective cohort study involving patients who were discharged alive from their first ICU admission with at least 24 hours of ICU length of stay (LOS). From January 2011 to August 2013, 723 patients were admitted to ICU and 383 patients were included. The estimated in-hospital mortality rate was 11...

Conducting semi-structured American Sign Language interviews with 17 Deaf trauma survivors, this pilot study explored Deaf individuals' trauma experiences and whether these experiences generally align with trauma in the hearing population. Most commonly reported traumas were physical assault, sudden unexpected deaths, and "other" very stressful events. Although some "other" events overlap with traumas in the general population, many are unique to Deaf people (e.g., corporal punishment at oral/aural school if caught using sign language, utter lack of communication with hearing parents)...

Causes of sudden cardiac deaths have been widely reported with limited data focused specifically on myocarditis. A retrospective review of cases from the Office of the Chief Medical Examiner (OCME), State of Maryland yielded a total of 103 sudden unexpected deaths (SUDs) due to myocarditis (0.17% of all SUDs and 0.70% of autopsied SUDs) from 2005 through 2014. Most deaths occurred in patients <30 years of age with a male:female ratio 1.3:1. Of the 103 cases, 45 (43.7%) patients were witnessed collapsed. Four deaths occurred during exertion, such as exercising at the gym or performing heavy physical work, and 2 deaths were associated with emotional stress...

The exact mechanisms of sudden unexpected death in epilepsy remain elusive, despite there is consensus that SUDEP is associated with severe derangements in the autonomic control to vital functions as breathing and heart rate regulation. Heart rate variability (HRV) has been advocated as biomarker of autonomic control to the heart. Cardiac dysautonomia has been found in diseases where other branches of the autonomous nervous system are damaged, as Parkinson disease and multiple system atrophy. In this perspective, an impaired HRV not only is a risk factor for sudden cardiac death mediated by arrhythmias, but also a potential biomarker for monitoring a progressive decline of the autonomous nervous system...
