When a child or adolescent with epilepsy dies, and their death is not caused by another illness or injury, this is called Sudden Unexpected Death in Epilepsy (SUDEP). To roll out the videos, the Epilepsy Foundation will be implementing a digital media campaign called #StartTheSUDEPConvo to inspire people to discuss SUDEP, educate people with epilepsy and their caregivers about the risks for SUDEP, and help them manage their epilepsy. One pattern consists of simultaneous increase of blood pressure and heart rate, whereas the second one shows an initial raise in blood pressure followed by a quick drop of blood pressure to baseline or even below preictal values, although with sustained tachycardia (37). Sci Transl Med 2015;7(282):282ra246. 2010 Dec 23;363(26):2522-9. Int J Mol Sci 2019;20(8):1979.**. and transmitted securely. Patodia S, Somani A, O'Hare M, et al. Resection of an occipital lobe epileptogenic network resulting in improvement of a visual field deficit: illustrative case. The videos honor the lives of those who have been lost to SUDEP and highlight stories of people who live with uncontrollable seizures and healthcare providers. Two groups emerged: five children with uncontrolled seizures receiving multiple AEDs and good compliance with medications, and 39 adults with less frequent seizures, often receiving monotherapy, but noncompliant with medications. Herlenius E, Lagercrantz H, Yamamoto Y. Adenosine modulates inspiratory neurons and the respiratory pattern in the brainstem of neonatal rats. there are a number of causes of increased mortality related to epilepsy, including those that are a direct cause (accidental death, sudden unexpected death in epilepsy [sudep], status epilepticus) and those that are epilepsy related (underlying brain diseases or comorbidities, suicides, complications of antiepileptic therapy). Potential role of antiepileptic drugs. Epilepsia 2016;57(10):1709-18. There are known risk factors which increase the chance of death in people with epilepsy.

Selective mutism: A somewhat rare disorder associated with anxiety is selective mutism.Selective mutism occurs when people fail to speak in specific social situations despite having normal language skills. Prolongation of postictal generalized electroencephalographic suppression is a marker of seizure severity and has been suggested as a premortem risk identifier and was noted in all cases of monitored sudden unexplained death in epilepsy in the MORTEMUS study (94). Moreover, selective serotonin reuptake inhibitors in humans are associated with reduced likelihood of ictal oxygen desaturation in patients with partial seizures and a decreased incidence of ictal central apnea (10; 55). Epilepsy Action Australia offers support and information to families and friends who have lost a loved one due to SUDEP or other epilepsy-related death. Ictal central apnea can start before, at, or after EEG seizure onset and is usually a self-limiting phenomenon (57). Maguire MJ, Jackson CF, Marson AG, Nolan SJ.

Sudden unexpected death in epilepsy: basic mechanisms and clinical implications for prevention. The risk of sudden death in young adults with epilepsy is increased 20-40-fold compared to the general population. Long QT syndrome: genetics and future perspective. Histopathologic studies of sudden unexplained death in epilepsy patients have shown focal gliosis within amygdaloid subnuclei as well as an increased right parahippocampal volume, in concordance with neuroimaging studies (114; 126; 103). SUDEP is not well understood. Cochrane Database Syst Rev. Read eJourneys about SUDEP: The Epilepsy Foundation has produced a video series to raise awareness about Sudden Unexpected Death in Epilepsy (SUDEP) and improve communication between patients and their healthcare providers. Epilepsia 1997;38(11 Suppl):S41-2. Over one-third of the time, there is a witnessed seizure or signs of a recent seizure close to the time of death. Aiba I, Noebels JL. Share your SUDEP story with the world. 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. Neurology 2017;88(3):296-303. Sarah is 6 years old and was diagnosed with epilepsy at age two. Ogren JA, Tripathi R, Macey PM, et al. Buchanan GF, Murray NM, Hajek MA, Richerson GB.

Administration of citalopram, a selective serotonin reuptake inhibitor, does not reduce mortality in Lmx1bf/f/p mice but it does in controls (16). Front Neurol 2019a;10:166. Brugada Syndrome They don't usually cause problems unless they happen regularly, perhaps because of emotional distress. Epilepsy Res 2016;125:10-8. Respiratory collapse was terminal in a third of patients and although transient restoration was found in the remainder, respiratory deterioration followed. This translates to a prolonged QT interval that predisposes to ventricular tachyarrhythmias such as torsade de pointes, which can degenerate into ventricular fibrillation and death (125). A significant number of deaths in people with epilepsy may be potentially preventable through better seizure control, regular monitoring and raising awareness among patients and carers. Thus, proning may be the consequence of forced ictal body version rather than sleeping prone (64). ER. J Neurol Neurosurg Psychiatry 1996;60(3):297-300. Sharing written stories, videos and photographs helps create understanding, support and increases awareness about SUDEP. An Error Occurred. For many people with epilepsy, the risk of seizures restricts their independence (some states refuse drivers licenses to people with epilepsy) and recreational activities. 2020 Nov;10(11):e01838. All experts involved in the development of these guidelines have submitted declarations of interest. ROCHESTER, Minn. - Sudden unexpected death in epilepsy, known as SUDEP, is a lethal medical problem that leaves many wondering what it's caused by. Finally, living conditions have an influence in sudden unexplained death in epilepsy risk. Cardiac factors: cardiac arrhythmias and other cardiac events are known to be involved in some cases of SUDEP. As a general group, people living with epilepsy are at a 1 in a 1000 risk of SUDEP per year. Possible factors include heart or breathing problems, perhaps related to genetic abnormalities.

Life Sci 1982;31(22):2425-32. Brain Behav. Neurology 2020;94(24):e2555-66. However, these associations were not corroborated in a population-based case-control study when age at onset and epilepsy duration were adjusted by generalized convulsive seizures frequency (107). Epilepsy Res 2016;124:49-54. It refers to deaths in people with epilepsy that are not from injury, drowning, or other known causes. 2014 Dec;7(4):160-4. doi: 10.1177/1753495X14553257. Brugada syndrome presents primarily during adulthood, although age at diagnosis may range from infancy to late adulthood. Moreover, it is associated with lower incidence and duration of postictal generalized EEG suppression (02). If a seizure happens, an alarm is triggered so that either a family member, friend or emergency services can be notified. However, the extent of the edema observed does not account for death. Amphetamine and dextroamphetamine Having active seizures can put you at risk, and there are certain types of seizures which can increase a persons risk of SUDEP. Spreading depolarization in the brainstem mediates sudden cardiorespiratory arrest in mouse SUDEP models. The risk of SUDEP for children with epilepsy is lower than adults (approximately 1 in every 4,500 children with epilepsy), but the risk factors are the same as for adults. Hampel KG, Jahanbekam A, Elger CE, Surges R. Seizure-related modulation of systemic arterial blood pressure in focal epilepsy.
