Traditionally a controversial topic discussed primarily by the neurological community, sudden unexplained death in epilepsy (SUDEP) is now emerging more frequently in research literature, Idiopathic Generalized Epilepsy (IGE) is the second most common type of epilepsy, after focal onset epilepsy 1. Sudden Unexpected Death in Epilepsy (SUDEP) is when a person with epilepsy dies suddenly and prematurely and no reason for death is found. Epilepsia 2020;61(4):787-97. A year after his in-patient EEG monitoring discharge, he was found dead in bed one morning by his mother. At times this is due to the underlying condition causing their epilepsy, or from injuries incurred during a seizure, or from a convulsive seizure that continues for a prolonged period without stopping (status epilepticus). 2002 Feb;42(2):123-36. doi: 10.1177/00912700222011157.

No increased risk for sudden unexplained death in epilepsy was found with psychiatric comorbidities once adjustment for generalized convulsive seizures frequency was applied (107). This comprised a postconvulsive, immediate increase in breathing rate followed by bradycardia and transient periods of apnea and asystole, along with postictal generalized EEG suppression. This observation is concordant with signs of increased sympathetic tone during epileptic seizures, such as increased levels of circulating catecholamines and elevated electrodermal activity (80; 81). 1 Most, but not all, cases of SUDEP happen during or right after a seizure.

Although the phenomenon of SUDEP was known as early as latter Postictal generalized electroencephalographic suppression is defined as the immediate postictal (within 30 seconds) generalized absence of electroencephalographic activity higher than 10 V in amplitude (63). In a mouse model of Dravet syndrome and sudden unexplained death in epilepsy, blockade of peripheral muscarinic receptors did not prevent postictal apnea, bradycardia, and death whereas selective central blockade of medullary muscarinic receptors did, suggesting a primary respiratory failure as the cause of cardiac arrest and death (50). MeSH Obstet Med. Neurology 2017;89(8):785-91. A diagnosis of definite sudden unexplained death in epilepsy was made. Definitions. There were 16 sudden unexplained death in epilepsy cases, 9 near-sudden unexplained death in epilepsy cases (2 of them subsequently fatal), and 4 deaths of other etiologies.

Considering the potential role of serotonin and adenosine in sudden unexplained death in epilepsy physiopathology, specific pharmacological strategies have been suggested targeting their respective pathways (91; 55; 75). Cochrane Database Syst Rev. Online ahead of print. Spreading depolarization has been noted in Kv1.1 KO and SCN1A mice, producing cardiorespiratory arrest preceded by EEG suppression and apnea (01). FOIA Currently, the most effective strategy to protect against SUDEP in childhood epilepsy is seizure control, but this approach is not completely effective and is particularly challenging in cases of intractable epilepsy. Postictal generalized electroencephalographic suppression is also linked to postictal tonic electromyographic activity, with direct correlation between postictal generalized electroencephalographic suppression duration and tonic electromyographic duration (85; 122). Ictal asystole has been proposed as benign and self-limiting, even as a mechanism of seizure termination, because asystole-induced reduction in cerebral blood flow potentially aborts perpetuation of the seizure discharge (98).

Thus, proning may be the consequence of forced ictal body version rather than sleeping prone (64). Tell your doctor if you have: heart problems or a congenital heart defect; high blood pressure; or. [2][3], While the mechanisms underlying SUDEP are still poorly understood, it is possibly the most common cause of death as a result of complications from epilepsy, accounting for between 7.5 and 17% of all epilepsy-related deaths[2] and 50% of all deaths in refractory epilepsy. Administration of fluoxetine has been shown to prevent seizure-induced respiratory arrest in a mouse model of sudden unexplained death in epilepsy (117; 33). Tavee J, Morris H 3rd.

Marini C, Scheffer IE, Nabbout R, et al. The ultimate physiopathology behind cardiorespiratory collapse is poorly understood, although there is circumstantial, neuroimaging, and neuropathological evidence of compromised brainstem function. Secondly, muscular hyperemia after generalized convulsive seizures may lead to a decrease in peripheral vascular resistance, resulting in a decrease in systemic blood pressure (80). Lastly, biosignals recorded interictally and during seizures may help identify patients at higher risk (93). The majority of these deaths are caused by Sudden Unexpected Death in Epilepsy (SUDEP), occurring often at night. Cardiovascular dysfunction. In a case control study, nocturnal generalized convulsive seizures were associated with a 9-fold risk for sudden unexplained death in epilepsy. In adult Lmx1bf/f/p mice, which lack more than 99% of serotoninergic neurons in the central nervous system, induction of seizures results in lower seizure threshold and increased seizure-induced mortality (16).

Acta Anaesthesiol Scand 2007;51(4):447-55. To date, the major risk factor for sudden unexplained death in epilepsy is the presence and frequency of generalized convulsive seizures and ongoing seizures despite adequate treatment (41; 39; 107). Goldman AM, Glasscock E, Yoo J, Chen TT, Klassen TL, Noebels JL. [4], SUDEP occurs in about 1 in 1,000 adults and 1 in 4,500 children with epilepsy a year. Front Neurol 2019;10:185. 8600 Rockville Pike It is more commonly seen in seizures arising from sleep (62; 84). This gene encodes the alfa subunit of the voltage gated potassium channel Kv7.1, the mutation of which is responsible for the abnormally slow repolarization current in cardiomyocytes.

Dravet syndrome (severe myoclonic epilepsy of infancy). Epilepsia 2000;41(5):542-8. Association of prone position with sudden unexpected death in epilepsy. So EL, Sam MC, Lagerlund TL. Sudden unexplained death (SUDEP) in epilepsy is often listed as a cause of death, accounting for 717% of deaths among the general population with epilepsy and perhaps 50% among patients with refractory epilepsy. SUDEP stands for Sudden Unexpected Death in Epilepsy. However, this is the final position sudden unexplained death in epilepsy cases are frequently found in, and not necessarily the patients natural sleep position. Conversely, adenosine promotes seizure termination and suppresses cardiorespiratory function by activation of its A1 receptors whereas blockage of A1 receptors or activation of A2a receptors has the opposite effect (30; 40; 15; 87). Long QT syndrome is autosomal dominant except long QT syndrome associated with sensorineural deafness (Jervell and Lange-Nielsen syndrome), which is autosomal recessive. 1.

Terminal asystole was always preceded by terminal apnea, suggesting apnea as the final mechanism of death, in line with previous animal models of sudden unexplained death in epilepsy (47; 94). Eighteen were judged by the panel to be SUDEP, 6 were defined as possible SUDEP, 20 were judged to be due to other causes (non-SUDEP), and 1 lacked sufficient data from which to make a classification. Impact of periictal interventions on respiratory dysfunction, postictal EEG suppression, and postictal immobility. Loonen ICM, Jansen NA, Cain SM, et al. But researchers have identified key risk factors that can increase risk of SUDEP and in some cases, there are positive things that can be done to reduce risks. Availability of cardiorespiratory data in 10 of 16 sudden unexplained death in epilepsy cases in MORTEMUS allowed identification of a relatively consistent pattern leading to death. Int J Mol Sci 2019;20(8):1979.**. Latreille V, Abdennadher M, Dworetzky BA, et al. SUDEP is the sudden, unexpected death of someone with epilepsy, who was otherwise healthy. Child Care/Camps/Rec.

What seems apparent, however, is that postictal generalized electroencephalographic suppression is frequently found associated with other markers of seizure severity. Epilepsy and seizure-related deaths: Mortality statistics do not tell the complete story. Ba-Armah DM, Donner EJ, Ochi A, et al. All monitored sudden unexplained deaths in epilepsy (11 of 16) and all near-sudden unexplained deaths in epilepsy had a seizure immediately prior to cardiorespiratory arrest.
