Lancet Neurol. SUDEP refers to deaths in people with epilepsy that are not caused by injury, drowning, or other known causes. In addition to this information, the NORD found that almost all children with SUDC were supposedly sleeping before they became unresponsive. SUDC and pediatric SUDEP share several features (14, 40, 62). But she said: An hour later I realised I hadnt heard any sounds on the baby monitor. A complete autopsy is the gold standard for understanding causes and consequences of lethal disease, and a detailed examination of the brain is necessary to identify potentially unexpected neurologic causes of death. Almost 60 percent of toddlers between the ages of one and four who die, die of SUDC. Brain findings were generally not discussed unless gross pathologic abnormalities were seen; i.e., hippocampal histology was not reported. 7. A developmental continuum has been proposed as a framework for SUID and SUDC, with the expectation that future advances in imaging and genomics will help resolve convergent mechanisms and pathways of relevance to both groups (39). They have all lost a son or daughter to sudden unexplained death in childhood but say too little is known about the condition. London: Royal College of Pathologists (2016). Understanding risk factors and the underlying biologic mechanisms of SUDC is essential for informing effective public health surveillance and developing strategies to mitigate risk in susceptible children. Filiano JJ, Kinney CH. Front Neurol. The age of epilepsy onset influences SUDEP risk, which increases with earlier onset epilepsy, implying that developmental mechanisms might influence vulnerability (62, 64). Comparable volumetric analyses in SUDC cohorts are lacking. A history of FS was present in ~60% of these SUDC cases, substantially more than previously reported cohorts and likely reflecting referral bias from forensic institutions with limited access to neuropathology expertise. Moreover, exome sequencing of SUDEP cases has identified an excess of variants in genes that regulate ion channels in cardiac and brain tissue (22, 23). Neurol. Medicolegal Death Investigation System: Workshop Summary. Perturbations of normal brain development resulting from de novo somatic mutations during embryonic or early post-natal development are increasingly recognized in multiple neurodevelopmental disorders including migration defects, epileptic encephalopathies, and other neuropsychiatric conditions, although a causal role in SUDC remains to be demonstrated (24, 25). Genet Med. Calderon-Garcidueas AL, Mathon B, Lvy P, Bertrand A, Mokhtari K, Samson V, et al. Families must be supported following such devastating loss. Children were in their state of usual good health prior to death, or had mild symptoms of illness such as cold symptoms or fever. Future detailed studies are necessary to elucidate the mechanism of hippocampal alterations, and explore connections with brainstem dysfunction. (2011) 7:33640. (1986) 31:15966. (2016) 374:244152. In contrast, SUDC has received relatively little attention, partly because it is such a rare condition The Sudden Death in the Young registry, under the auspices of the Centers for Disease Control and Prevention and the National Institutes for Health is responsible for tracking unexplained infant as well as childhood deaths, although just 13 states or jurisdictions actively participate in this program (75, 76). doi: 10.1016/j.resp.2018.03.004, 67. (2009) 118:51930. doi: 10.1002/ana.24596, 23. She said: We do it in our childrens memories so they didnt die in vain., Get email updates with the day's biggest stories. Arch Dis Child. The 15-year-old, from Witney, Oxon, was running for a bus with his brother after a football match when he collapsed and died in January 2020. Whether these changes are necessary or sufficient to cause seizures in SUDC remains unproven and controversial (16, 45, 46). doi: 10.1111/epi.12489, 24. Narula N, Tester DJ, Paulmichl A, Maleszewski JJ, Ackerman JM. Krous HF, Chadwick AE, Crandall L, Nadeau-Manning MJ. Chai X, Munzner G, Zhao S, Tinnes S, Kowalski J, Haussler U, et al. By definition, autopsy examination and ancillary studies are negative or reveal only minor pathologic changes insufficient to explain death. There has not been enough research to identify risk factors, common characteristics, or prevention strategies for SUDC. Although epidemiologic data support a link between neuropathologic changes, FS history, and SUDC, the nature of this association is poorly understood. However, stigmata of convulsive seizures may be absent. SUDC UK co-founder Camilla, 48, of Westerham, Kent, said: I became so paranoid about the other children I trained as a nutritional therapist to understand their immune systems. In most SUDC cases, children are healthy and do not necessarily exhibit any symptoms., NORD stated on their website, Most were born as full-term singletons and their development was considered normal. The mum, 41, of Shepperton, Surrey, said she and husband Christian took him to hospital each time and were sent home with Calpol. doi: 10.1007/s00401-014-1357-0, 44. All authors were involved in the conception, literature review, writing, and editing. Sidebotham P, Bates F, Ellis C, Lyus L. Preventive strategies for sudden infant death syndrome. 29. doi: 10.20851/sids-29, 41. First defined in 2005, SUDC cases are more often male, with death occurring during a sleep period, being found prone, peak winter incidence, associated with febrile seizure history in ~28% of cases and mild pathologic changes insufficient to explain the death (1, 2). Successful educational and public health campaigns have substantially reduced the burden of SUID (11, 74). Hesdorffer DC, Crandall LA, Friedman D, Devinsky O. Read This Before You Enjoy the Satisfaction of Cracking Your Joints! Sign up for our newsletter. Sudden death, febrile seizures, and hippocampal and temporal lobe maldevelopment in toddlers: a new entity. (2013) 12:96677. a comparison of cases with and without a febrile seizure history. Pediatrics. Grateful Claire Bowie draws great strength from sharing her heartbreak with the other mums. First defined in 2005, SUDC cases are more often male, with death . You still need to be extra vigilant about your childs health and behaviour even as he grow older., Its always better to be safe than sorryequip yourself with relevant information about this phenomenon., Sources: Babble, SUDC, Rare Diseases, NCBI, Centres for Disease Control and Prevention, ALSO READ: 7 serious childhood illnesses that seem harmless at the onset. These symptoms of the following illnesses can sometimes be similar to thesudden unexplained death of a child. While it is difficult to exact the cause of SUDC, there are a few possibilities., NORD lists a few possible reasons for sudden unexplained death in a child., It has to be noted that these are yet to be proved as the exact cause of SUDC. Exome-based analysis of cardiac arrhythmia, respiratory control, and epilepsy genes in sudden unexpected death in epilepsy. Unlike temporal lobe epilepsy, hippocampal sclerosis is rare or never occurs in SUDC while acquired hippocampal injury (e.g., neuronal loss or gliosis) is uncommon in SUDC (13, 15, 16). Proc Natl Acad Sci USA. However, researchers have since raised concerns about the reliability of the association in the SDSRP study, as hippocampal tissue was unavailable for analysis in approximately half the cases (46). Unlike prior reports, GCD or FDGB, were not prominent findings, raising questions about the importance of this finding as a morphologic marker of SUDC in this cohort. Other studies have identified similar trends, and countries that routinely track SUDC mortality report a gradual increase in incidence over time (4, 8385). So it was a promise I was keeping to him.. doi: 10.1007/s10024-005-1155-8, PubMed Abstract | CrossRef Full Text | Google Scholar, 2. (1989) 159:2214. (2012) 87:52439. J Neuropathol Exp Neurol. Deepshikha worked as the Head of Web Content and was previously the Regional Dy. She didnt suffer from any illness, nor did she have any childhood infections. School business manager Kate, 50, who also has two grown-up children with husband Liam, 53, said: At the top of Snowdon there is a quote that says you are nearer to heaven. Pediatrics. However, it occurs more frequently in people whose seizures are poorly controlled.. Then why did she die?. Pediatr Neurol. | Image courtesy: Pixabay, In addition to this information, the NORD found that almost all children with SUDC were supposedly sleeping before they became unresponsive., You might wonder, if it is unexplained then how can there be a cause? (2007) 28:2717. What is SUDC?It is the lesser-known cousin of Sudden Infant Death Syndrome (SIDS), which theCenters for Disease Control and Prevention (CDC)defines as the sudden death of an infant less than one year of age that cannot be explained after a thorough investigation is conducted, including a complete autopsy, examination of the death scene, and review of the clinical history., Whatmany parents dont know is that even older children can die suddenly and from no apparent cause.. Sudden unexplained death in children. An association of hippocampal malformations and sudden death? Adelaide, SA: University of Adelaide Press (2018). doi: 10.1001/archinte.1995.00430210096015. Pediatrics. This is a non-traumatic and sudden death of a child or an adult with epilepsy. "It was like a bad movie." (2016) 18:7469. Neuropathol Appl Neurobiol. Biol Neonate. It is a rare genetic disorder. We hope by shining their lighton SUDC, we can better understand these tragedies in order to predict and prevent them in the future. In some cases, a distinction between SUDC and SUDEP may be semantic as some SUDC cases had epilepsy syndromes retrospectively diagnosed based on genetic and other data, but epilepsy was not recognized before death. Hefti MM, Cryan JB, Haas EA, Chadwick AE, Crandall LA, Trachtenberg FL, et al. NCfHS Centers for Disease Control and Prevention. As with SUID, abnormalities of the serotonergic system and other neurotransmitter systems are implicated in SUDEP; the 5-HT type 2c receptor knockout mouse is an animal model of SUDEP with spontaneous seizures leading to respiratory arrest and death within seconds of onset (10, 71). The structural changes in the hippocampus may be secondary to interictal or ictal discharges (44). (1987) 62:7005. Neuropathology provides new insight in the pathogenesis of the sudden infant death syndrome. Am J Forensic Med Pathol. In Ireland, SUID deaths were cut in half from 1994 to 2008 while SUDC deaths more than doubled (4). Structural imaging biomarkers of sudden unexpected death in epilepsy. Hoffman HJ, Damus K, Hillman L, Krongrad E. Risk factors for SIDS. The NORD explains the three illnesses as follows: This is a non-traumatic and sudden death of a child or an adult with epilepsy. New clinicopathological associations and histoprognostic markers in ILAE types of hippocampal sclerosis. Retrospective, small SUDC studies with non-standardized methodologies most often demonstrate minor hippocampal abnormalities, as well as focal cortical dysplasia and dysgenesis of the brainstem and cerebellum. We use cookies to ensure that we give you the best experience on our website. 8. However, it occurs more frequently in people whose seizures are poorly controlled.. In children 1 year of age or older, it's called sudden unexplained death in children (SUDC). Keeling JW, Knowles AS. Table 1. The estimated FS prevalence of ~12% in the general pediatric population, and a low overall SUDC annual incidence, suggests additional factors modulate risk of SUDC in susceptible children, although data are limited regarding specific genetic variants influencing risk. (2000) 97:147316. These deaths elude our scientific understanding. doi: 10.1007/s12024-015-9731-3, 17. The third related complication that can cause, or is related to the sudden unexplained death of a child, is an inborn metabolic error. (2012) 46:2359. We also may change the frequency you receive our emails from us in order to keep you up to date and give you the best relevant information possible. Sudden Unexplained Death in Childhood (SUDC) is relatively unknown though it is the 5th leading classification of death in toddlers. Sudden unexplained death in childhood (1-4 years) in Ireland: an epidemiological profile comparison with SIDS. Acta Neuropathol. Sudden unexplained death of a child cannot be stopped. Arch Dis Child. Not all SUDC cases with FS history are associated with hippocampal changes suggesting other mechanisms are likely relevant in some instances (12, 16). 74. doi: 10.1136/adc.62.7.700, 82. The sudden infant death syndrome. Multiple Cause of Death 1999-2017 on CDC WONDER Online Database. However, Dr Krous says there is hope because parents can take preventive measures.. You still need to be extra vigilant about your childs health and behaviour even as he grow older. The proportional contribution of central nervous system disorders to this shared phenotype is unknown. Standardized, unrestricted whole brain examination is essential to elucidate the structural abnormalities, if any, in the SUDC brain. Moreover, the extent to which GCL alterations overlap with normal anatomic variation requires further clarification. If and when risk factors are identified, such as prone sleep position for SIDS, then one might anticipate reduction in the risk of SUDC., These symptoms of the following illnesses can sometimes be similar to thesudden unexplained death of a child. She didnt suffer from any illness, nor did she have any childhood infections. If and when risk factors are identified, such as prone sleep position for SIDS, then one might anticipate reduction in the risk of SUDC.. (2006) 296:212432. Population-based data of all-cause mortality affecting children aged 14, identifies ill-defined or unknown causes of death (R99), twice as frequently in African American children, underscoring that some SUDC cohorts have suffered selection bias in case ascertainment (7).

Dentate granule cell neurogenesis is increased by seizures and contributes to aberrant network reorganization in the adult rat hippocampus. One audit of SUDC autopsy practice found improved reporting when autopsies were performed by pediatric pathologists compared to non-specialists (27). Sudden Unexplained Death in Childhood (SUDC) is a category of death in children between the ages of 1 and 18 that remains unexplained after a thorough investigation, including an autopsy. doi: 10.2350/08-09-0542.1, 14. (1994) 94(2 Pt 1):14856. She wasnt sick. Little did she expect that they would call to inform her about the sudden unexplained death of a child she loved with all her heart her darling little girl Candice. Given these converging strands of evidence, hippocampal abnormalities have emerged as a potential risk factor for seizure-like mechanisms responsible for SUDC, potentially mediated through apneic seizures and cardiorespiratory dysregulation (40). SUDC likely represents a phenotypic endpoint for a heterogeneous group of underlying disorders, the mechanisms of which remain poorly defined. The mums climbed the Welsh mountain in September to raise awareness and 8,000 for SUDC UK, a charity co-founded by Dr Nikki Speed, 43, of Hertfordshire. D'Gama AM, Walsh AC. This work was supported by the SUDC Foundation and Finding a Cure for Epilepsy and Seizures (FACES). Finally, even in adults with epilepsy, sudden death can occur during video electroencephalogram (EEG) monitoring without clinical or electrographic evidence of a seizure, and autopsies reveal no alternative causes. As morphometric analysis was not conducted the possibility of heightened sensitivity and observer bias to specific lesions, particularly in more subtle cases, cannot not be entirely excluded. Forensic Sci Med Pathol. J Pathol. These are only suspected causes. These cases challenge the under-resourced and non-standardized U.S. medicolegal death investigation system, leaving a devastating impact on affected families (8, 9). Doctors think he may have had another seizure. FS history might represent an independent marker for SUDC, with the caveat that not all FS are clinically obvious, and FS are probably underreported (2, 17). |Image courtesy: Pixabay, It could happen to a healthy child as well, and death comes almost immediately. The potential for seizure-like events precipitated by exogenous stressors remains speculative and shares similarities with the triple risk model of SUID (5). Unexpected death of a child with complex febrile seizures-pathophysiology similar to sudden unexpected death in epilepsy? Nonseizure SUDEP. Half of SUDC cases showed HMASD with or without a FS history and the most frequent histologic findings in this group were GCD, FDGB, irregularity of the DG, and ectopic granule cells. SIDS Sudden Infant and Early Childhood Death. On the basis of the probable causes of sudden unexplained death of a child, NORD suggests that one must keep an eye out for signs of seizures. Adelaide, SA: University of Adelaide Press (2018). Norman MG, Taylor GP, Clarke AL. doi: 10.1038/374542a0, 72. SUDC is the sudden and unexpected death of a child between 1 and 18 years of age, which remains unexplained after a thorough investigation is conducted. Read articles or ask away and get instant answers on our app. (1990) 10:76984. It is hoped that future research will identify means by which SUDC can be prevented. Dlouhy BJ, Ciliberto MA, Cifra CL, Kirby PA, Shrock DL, Nashelsky M, et al. High-resolution molecular genomic autopsy reveals complex sudden unexpected death in epilepsy risk profile. Mechanisms of sudden unexpected death in epilepsy: the pathway to prevention. The coroner told me, We can put a man on the moon, but I cant explain why your beautiful, healthy child went to bed and never woke up., Becca, 42, has walked miles to raise SUDC funds. Bagnall RD, Crompton DE, Petrovski S, Lam L, Cutmore C, Garry SI, et al. Pediatr Dev Pathol. Thus, the SUDC Registry and Research Collaborative (SUDCRRC) at NYU Langone Health undertook a 5-year prospective analysis of 20 SUDC cases accrued through a registry where systematic sampling of whole brains was performed with blinded independent reviews conducted by neuropathologists (15). SUDC is the sudden death of a child 1-18 years old that remains unexplained after a thorough autopsy . The small sample size due to the rarity of SUDC, limited access to true normal controls such as pediatric trauma, or children without medical comorbidities, and a hippocampal sampling bias, necessarily require that conclusions about the relative contribution of hippocampal abnormalities in SUDC should still remain tentative. Get advice on your pregnancy and growing baby. JAMA. Some children with SUDC had a history of febrile seizures, or a family history of febrile seizures., Dr. Henry Krous, former director of the San Diego SUDC research project (2001 to 2012) alsoexplains, At the present time, there is no way to prevent SUDC as its cause(s) is not known. It is a rare genetic disorder. Marketing manager Julia Rogers said her son Louis had three febrile seizures before he died at just 22 months old. However, in the United States sudden unexpected pediatric deaths are investigated by a non-uniform medico-legal investigation system consisting of over 2,000 autonomous jurisdictions run by a mixture of physician medical examiners and lay coroners (26). But meeting Nikki and Camilla was such a relief. Protocols for the investigation of unexpected infant death and recently published guidelines for SUDC are available; however, implementation remains problematic due to the persistent and systematic challenges described above (8, 2831). Neuropathologic research in SUDC has focused primarily on the hippocampus, with speculative mechanisms of a limbic-brainstem network disorder contributing to epileptogenesis and brainstem dysfunction in susceptible children (48, 56). Viewing a tiny fraction of a complex picture may lead to spurious conclusions perhaps most dangerous, they may close the door to more relevant pathogenic structures or functional systems. Lacuey N, Zonjy B, Londono L, Lhatoo DS. While it is difficult to exact the cause of SUDC, there are a few possibilities. Brainstem serotonergic and autonomic nuclei are critical in controlling arousal as well as cardiorespiratory centers that respond to life-threatening hypoxia or hypercarbia during sleep. The registry provided ex vivo MRI imaging and brain examination by a board-certified neuropathologist. Front Neurosci. Limited and inconsistent evidence implicates abnormalities in brainstem autonomic and serotonergic nuclei, critical for arousal, cardiorespiratory control, and reflex responses to life-threatening hypoxia or hypercarbia in sleep (6). (1997) 17:372738. (2016) 12:1989. Despite reductions in sudden unexpected infant death (SUID) and other causes of mortality in childhood, the rate of SUDC has increased during the past two decades (35). J Neurosci. doi: 10.1056/NEJMra0803836, 43. (1988) 533:1330. The investigators suggested that a malformed hippocampus could predispose to seizure development during sleep when seizure risk is greatest, however, this analysis also revealed comparable SUDC rates in cases that lacked hippocampal changes, raising doubts whether this finding is signal or noise. doi: 10.1111/bpa.12596, 45. But if there is a family history of any of these conditions, its best to get your child checked with a specialist at least once, for peace of mind. doi: 10.23907/2017.020, 32. doi: 10.1016/j.forsciint.2012.08.024. doi: 10.1016/S0140-6736(98)05114-9, 65. Although the genetic factors influencing SUDC vulnerability remain largely unknown, similarities with SUID and SUDEP, suggest seizure or cardiac related mechanisms are relevant in many cases. These changes also occur in experimental animal models where hippocampal stimulation evokes cardiorespiratory effects (48, 6567). Excessive activation of mTOR in postnatally generated granule cells is sufficient to cause epilepsy. The editor and reviewer's affiliations are the latest provided on their Loop research profiles and may not reflect their situation at the time of review. 58. A risk profile for SUDC has emerged over the past decade; most reported cases affect white non-Hispanic boys who were the product of a full-term pregnancy, with a median age of 1.6 years, (range 13 years) (1, 8).
