OBJECTIVE: To review studies on structural pulmonary and cardiac changes in SUDEP cases as well as studies showing pulmonary or cardiac structural changes in living epilepsy patients. METHODS: We conducted electronic literature searches using the PubMed database for articles published in English, regardless of publication year, that included data on cardiac and/or pulmonary structural abnormalities in SUDEP cases or in living epilepsy patients during the postictal period...

A recent article by Farrell et al. characterizes the phenomenon, mechanisms, and treatment of a local and severe hypoperfusion/hypoxia event that occurs in brain regions following a focal seizure. Given the well-established role of cerebral ischemia/hypoxia in brain damage and behavioral dysfunction in other clinical settings (e.g., stroke, cerebral vasospasm), we put forward a new theory: postictal hypoperfusion/hypoxia is responsible for the negative consequences associated with seizures. Fortunately, inhibition of two separate molecular targets, cyclooxygenase-2 (COX-2) and l-type calcium channels, can prevent the expression of postictal hypoperfusion/hypoxia...

A survey of 146 pediatric care providers (PCPs) revealed that 75.3% were unaware that children with epilepsy were at risk of death, specifically from sudden unexpected (or unexplained) death in epilepsy (SUDEP). PCPs assume that the treating neurologist discusses these risks. Increasing PCPs' knowledge of SUDEP will help address the care gap related to informing families about SUDEP.

Sudden unexpected death in epilepsy (SUDEP) is a devastating epilepsy complication, and no effective preventive strategies are currently available for this fatal disorder. Clinical and animal studies of SUDEP demonstrate that seizure-induced respiratory arrest (S-IRA) is the primary event leading to death after generalized seizures in many cases. Enhancing brain levels of serotonin reduces S-IRA in animal models relevant to SUDEP, including the DBA/1 mouse. Given that serotonin in the brain plays an important role in modulating respiration and arousal, these findings suggest that deficits in respiration and/or arousal may contribute to S-IRA...

Sudden unexpected death in epilepsy (SUDEP) is one of the most frequent causes of death among patients with epilepsy. Most SUDEP or near-SUDEP are unwitnessed and not observed or recorded during video-EEG recording in epilepsy monitoring units. This report describes a young woman with post ictal apnea and generalized EEG suppression (PGES) after a secondary generalized tonic-clonic seizure (sGTCS). This was accompanied by bradycardia and then ventricular tachycardia (VT). But at the end of VT, the patient's breath recovered without any intervention, such as cardio-respiratory resuscitation...

BACKGROUND: Sudden unexpected death in epilepsy (SUDEP) is probably due to an autonomic failure in the early postictal phase after bilateral convulsive seizures (BCS) in the majority of cases. The baroreflex sensitivity (BRS) is an established and reliable biomarker of autonomic function and sudden cardiac death. OBJECTIVE: To investigate whether postictal BRS depends on seizure type. METHODS: Beat-to-beat systemic blood pressure and heart rate were continuously and non-invasively recorded with the ccNexfin(®) device in patients with focal epilepsy undergoing video-EEG monitoring...

OBJECTIVE: Sudden unexpected death in epilepsy (SUDEP) is a common cause of death in epilepsy and frequently occurs following generalized tonic-clonic seizures (GTCS) in sleep. Postictal generalized electroencephalography (EEG) suppression (PGES), postictal immobility, and periictal respiratory dysfunction are potential risk factors for SUDEP. We sought to determine whether there was a difference in respiratory dysfunction, PGES, and postictal immobility for GTCS occurring during wakefulness or sleep...

BACKGROUND: Cardiac problems have been suggested as causes of sudden unexpected death in epilepsy (SUDEP). Our aim was to investigate possible associations of cardiac autonomic functions based on heart rate variability (HRV) parameters with risk factors of SUDEP in patients with drug-resistant epilepsy. METHODS: Forty-seven patients with drug-resistant seizures and 45 healthy control subjects were enrolled in the study. Interictal time domain parameters of HRV were evaluated with 24-hour Holter recordings...

Seizure spread into autonomic and respiratory brainstem regions is thought to play an important role in sudden unexpected death in epilepsy (SUDEP). As the clinical dataset of cases of definite SUDEP available for study grows, evidence points to a sequence of events that includes postictal apnea, bradycardia, and asystole as critical events that can lead to death. One possible link between the precipitating seizure and the critical postictal sequence is seizure-driven laryngospasm sufficient to completely obstruct the airway for an extended period, but ictal laryngospasm is difficult to fully assess...

Autonomic dysfunction may account for sudden unexpected death in patients with epilepsy (PWE). On the other hand, low cardiovascular fitness, which may affect autonomic function, is a risk factor for sudden death and all-cause mortality in the general population. Little is known about autonomic variables and cardiovascular response to exercise in PWE. We submitted thirty consecutive PWE with no known cardiovascular diseases to maximal treadmill test, comparing them with matched controls. All individuals were submitted to clinical assessment, 12-lead electrocardiogram (ECG) and echocardiogram to exclude cardiovascular disease...

OBJECTIVE: Lack of standardized terminology on death certificates (DCs) of SUDEP type cases may obscure the presence of epilepsy in these deaths. Most DCs for individuals dying unexpectedly with epilepsy are certified by medical examiners (MEs). The purpose of this study was to gauge death certification practices of MEs when interpreting SUDEP cases and assess implications for valid surveillance of SUDEP. MATERIALS AND METHODS: A survey consisting of clinical vignettes describing deaths in individuals with epilepsy was sent to medical examiners...

INTRODUCTION: Sudden unexpected death in epilepsy (SUDEP) is the most frequent cause of premature death in epileptic patients. Most SUDEP events occur at night and frequently go unnoticed; the exact pathophysiological mechanisms of this phenomenon therefore remain undetermined. Nevertheless, most cases of SUDEP are attributed to an infrequent yet extremely severe complication of epileptic seizures. DEVELOPMENT: We conducted a systematic literature search on PubMed...

BACKGROUND: Sudden unexpected death in epilepsy (SUDEP) is a major cause of death in patients with epilepsy. Several risk factors have been implicated, including early age of onset, tonic-clonic seizures and antiepileptic drugs. However, whether patients who die from SUDEP have a greater frequency of seizures in the few months before death is unclear. We investigated the terminal seizure frequency and its relation to SUDEP among a large group of patients with tonic-clonic seizures in rural West China...

The North American SUDEP Registry (NASR) is a repository of clinical data and biospecimens in cases of sudden unexpected death in epilepsy (SUDEP), a leading cause of epilepsy-related deaths. We assessed whether bereaved families were aware of SUDEP before their family member's death and their preferences for SUDEP disclosure. At enrollment, next-of-kin of SUDEP cases completed an intake interview, including questions assessing premorbid SUDEP discussions. Only 18.1% of the 138 next-of-kin recalled a previous discussion of SUDEP with a healthcare provider or support resource...

Since the findings of a Fatal Accident Inquiry (FAI) in 2010, clinicians working in Scotland have been advised to discuss the risk of Sudden Unexpected Death in Epilepsy (SUDEP) with patients immediately or soon after a diagnosis of epilepsy is made. A thematic analysis was used to describe the experiences discussing SUDEP of 10 clinicians (six Consultant Neurologists and four Neurology Registrars) working in Scotland. Contrary to previous research, clinicians appear to be routinely discussing SUDEP in a standardized fashion with newly diagnosed patients and the FAI appears to have instigated this change in practice...
