Drgawki
Epidemiologia
Drgawki stanowią istotny problem zdrowotny o zróżnicowanej epidemiologii, z częstością występowania 3,7 na 1000 osób rocznie i zapadalnością na ostre drgawki objawowe na poziomie 29-39/100 000 osób rocznie w USA. Ryzyko nawrotu drgawek po pierwszym uogólnionym napadzie toniczno-klonicznym wynosi około 35% u dorosłych i 50% u dzieci, wzrastając znacząco po kolejnych napadach. Występowanie drgawek ma charakter dwumodalny, z najwyższą zapadalnością u niemowląt (100-233/100 000) oraz osób starszych powyżej 65 roku życia (100-170/100 000). Istotne są także różnice demograficzne – mężczyźni wykazują wyższe ryzyko (stosunek mężczyzn do kobiet 1,4-1,85:1), a osoby rasy czarnej częściej korzystają z opieki na SOR z powodu drgawek. Drgawki noworodkowe występują z częstością 1,5-5,5/1000 noworodków, a drgawki gorączkowe dotyczą około 25% populacji dziecięcej, z częstością 6,4-112/100 000 w różnych badaniach. W starszej populacji drgawki i padaczka są częste, z zapadalnością ostrych drgawek objawowych do 1/1000 osobolat u osób powyżej 60 lat, a padaczka dotyka 1 na 67 seniorów, co wiąże się z wyzwaniami diagnostycznymi i możliwym powiązaniem z chorobą Alzheimera.
Epidemiologia Drgawek
Drgawki stanowią istotny problem zdrowotny dotykający znaczącą część populacji na całym świecie. Według dostępnych danych szacuje się, że około 8-10% populacji ogólnej doświadczy przynajmniej jednego epizodu drgawkowego w ciągu życia, w porównaniu do około 3% osób, które rozwiną pełnoobjawową padaczkę (charakteryzującą się nawracającymi, nieprowokowanymi napadami drgawkowymi)12. W Stanach Zjednoczonych drgawki odpowiadają za około 1 milion wizyt na oddziałach ratunkowych rocznie, co stanowi około 1% wszystkich wizyt na SOR34.
Wskaźniki epidemiologiczne drgawek
Zapadalność na ostre drgawki objawowe (wywoływane przez określone czynniki) szacuje się na 29-39 przypadków na 100 000 osób rocznie w Stanach Zjednoczonych56. Natomiast częstość występowania pojedynczych nieprowokowanych napadów wynosi 23-61 przypadków na 100 000 osobolat7. Te różnice w szacunkach mogą wynikać z odmiennych metodologii i definicji stosowanych w badaniach, jak wskazuje Beghi i współpracownicy8.
Populacyjny wskaźnik występowania drgawek wynosi 3,7 na 1000 osób rocznie9. W przypadku dorosłych, którzy doświadczyli pierwszego uogólnionego napadu toniczno-klonicznego, ryzyko nawrotu w ciągu pięciu lat wynosi około 35%, ale wzrasta do 75% u osób, które miały drugi napad10. U dzieci ryzyko nawrotu w ciągu pięciu lat po pojedynczym nieprowokowanym napadzie drgawkowym wynosi około 50%, a po dwóch nieprowokowanych napadach wzrasta do około 80%11.
Różnice demograficzne w epidemiologii drgawek
Występowanie drgawek wykazuje znaczące różnice w zależności od wieku, płci i pochodzenia etnicznego. Wskaźniki zapadalności na ostre drgawki objawowe są najwyższe wśród niemowląt i małych dzieci, następnie u osób powyżej 75 roku życia, a najniższe wśród osób w wieku 25-34 lat12. Ogólnie rzecz biorąc, częstość występowania drgawek ma rozkład dwumodalny w kształcie litery U, z najwyższymi wskaźnikami obserwowanymi u małych dzieci i osób starszych1314.
Wskaźnik występowania drgawek u niemowląt poniżej 1 roku życia wynosi 100-233 na 100 000. Wskaźnik ten spada u pacjentów w wieku 20-60 lat do 30-40 przypadków na 100 000, ale ponownie wzrasta do 100-170 przypadków na 100 000 u pacjentów powyżej 65 lat15. Ta tendencja jest również obserwowana w badaniach padaczki, gdzie zapadalność jest szacowana na 50-60 na 100 000 osobolat16.
Badania wykazują nieznaczną przewagę występowania drgawek u mężczyzn w porównaniu do kobiet1718. Stosunek mężczyzn do kobiet w przypadku wizyt na oddziałach ratunkowych związanych z drgawkami wynosi około 1,4:119. Podobnie, stosunek mężczyzn do kobiet w przypadku ostrych drgawek objawowych na poziomie populacyjnym (nie w warunkach SOR) wynosi około 1,85:1 (ryzyko w ciągu życia 5,0% u mężczyzn i 2,7% u kobiet)20.
Istnieją również różnice etniczne w występowaniu drgawek. Osoby rasy czarnej mają wyższe prawdopodobieństwo wizyt na oddziałach ratunkowych związanych z drgawkami w porównaniu do osób rasy białej21. Badanie przeprowadzone w USA wykazało, że wizyty związane z drgawkami stanowiły proporcjonalnie wyższy odsetek wśród pacjentów rasy czarnej niż wśród osób rasy białej22.
Drgawki w różnych populacjach
Drgawki u dzieci
Drgawki występują częściej w okresie noworodkowym niż w jakimkolwiek innym okresie życia, najczęściej w pierwszym tygodniu życia. Zgłaszana częstość występowania waha się od 1,5 do 5,5 na 1000 noworodków i może być jeszcze wyższa u wcześniaków. Częstość występowania drgawek zmienia się w zależności od niektórych specyficznych czynników ryzyka, wzrastając wraz ze zmniejszającym się wiekiem ciążowym i masą urodzeniową oraz zwiększającą się ostrością choroby23.
Większość drgawek noworodkowych (około 85%) to ostre drgawki prowokowane (wcześniej nazywane ostrymi drgawkami objawowymi), występujące w konsekwencji określonej, możliwej do zidentyfikowania etiologii24.
W badaniu przeprowadzonym w regionie Trans-Bajkalskim w latach 2004-2013, częstość występowania drgawek niegorączkowych (afebrile seizures, AS) wahała się od 0,23% (64 przypadki w 2005 r.) do 0,49% (128 przypadków w 2008 r.). Wskaźnik chorobowości dla AS wzrósł z 1,37 (431 przypadków w 2004 r.) do 4,71 (1232 przypadki w 2013 r.) na 1000 populacji pediatrycznej. Drgawki niegorączkowe przeważały u dzieci w wieku od 3 lat i 1 miesiąca do 7 lat. Stosunek liczby przypadków AS między chłopcami a dziewczętami wahał się od 1:1,1 do 1,1:125.
Drgawki gorączkowe dotykają znaczną część populacji dziecięcej. Według niektórych doniesień około 25% dzieci jest dotkniętych tego rodzaju drgawkami26. W badaniu przeprowadzonym w Brazylii stwierdzono częstość występowania łagodnych drgawek gorączkowych na poziomie 6,4/1000 mieszkańców (95% CI, 3,8-10,1), co jest znacznie niższe niż wyniki zgłoszone w dwóch innych badaniach przeprowadzonych również w Brazylii, wahające się od 13,9 do 16,0/1000, ale mieści się w zakresie literatury, od 3,5/1000 w populacji arabskiej do 17,0/1000 w wiejskiej populacji północnoamerykańskiej27.
W badaniu przeprowadzonym w Krasnojarsku częstość występowania drgawek gorączkowych wśród dzieci w wieku 0-14 lat wahała się od 75 do 112 na 100 000 populacji dziecięcej w latach 2009-2012. Największą liczbę przypadków drgawek gorączkowych zarejestrowano w 2010 r. – 177 (30,6%), a najniższą w 2009 r. – 130 (22,5%)28.
Drgawki u osób starszych
Drgawki i padaczka są częste u starszych dorosłych. Prawie połowa nowo rozpoznanych drgawek występuje u osób powyżej 65 roku życia. Rozpoznawanie drgawek w tej populacji jest jednak trudne ze względu na napadowy charakter stanu i klinicznie subtelną prezentację drgawek w większości przypadków29.
Wiek jest niezależnym czynnikiem ryzyka rozwoju drgawek i padaczki. Ostre drgawki objawowe są częste u starszych pacjentów. Częstość występowania ostrych drgawek objawowych u pacjentów powyżej 60 roku życia szacuje się na 0,55 do 1 na 1000 osobolat, z liniowym wzrostem co dekadę po 30 roku życia30.
Częstość występowania i rozpowszechnienie padaczki (nawracające nieprowokowane drgawki) również wzrasta z wiekiem w okresie dorosłości i jest najwyższe u pacjentów powyżej 75 roku życia31. Według danych z Wielkiej Brytanii, jedna na cztery osoby nowo zdiagnozowane z padaczką ma ponad 65 lat. Jeden na 67 seniorów cierpi na padaczkę, a liczba ta prawdopodobnie będzie nadal rosnąć32.
Nowe odkrycia sugerują, że niewyjaśnione drgawki u starszych dorosłych mogą być wczesnym objawem choroby Alzheimera. Drgawki mogą być objawem zaawansowanej demencji, ale występują również u starszych dorosłych z łagodnymi lub bez objawów pogorszenia funkcji poznawczych33.
Nadzór i monitorowanie drgawek
Wyzwania w nadzorze epidemiologicznym
Istniejące dane z nadzoru nad drgawkami nie dostarczają aktualnych lub kompletnych informacji o tym, jak to zaburzenie wpływa na populację. Obecnie dane związane z drgawkami nie są standaryzowane w różnych badaniach, co ogranicza dokładność ustalania przypadków i kodowania oraz utrudnia monitorowanie usług zdrowotnych i jakości życia34.
Działania niezbędne do dostarczenia bardziej aktualnych informacji na temat szeregu kluczowych atrybutów drgawek, takich jak zapadalność, chorobowość, choroby współistniejące, wykorzystanie usług i koszty, obejmują standaryzację definicji i kryteriów nadzoru nad drgawkami i badań nad nimi, a także kontynuację i rozszerzenie gromadzenia danych związanych z drgawkami z różnych źródeł35.
Zwiększające się wykorzystanie elektronicznych rejestrów medycznych, które mogą być łączone między dostawcami i płatnikami, może ułatwić gromadzenie danych z nadzoru36.
Wyzwania metodologiczne w badaniach nad drgawkami
Poprawa nadzoru nad drgawkami będzie wymagała przezwyciężenia kilku wyzwań w pomiarach i metodologii. Wiele obecnie gromadzonych danych nie może być zweryfikowanych, nie są porównywalne, nie mogą być wykorzystane do zrozumienia trendów w czasie, nie są reprezentatywne dla populacji USA i nie mogą być analizowane dla ważnych podgrup populacji37.
Wśród głównych problemów pomiarowych i metodologicznych, które stanowią przeszkody w nadzorze nad drgawkami i badaniach nad nimi, można wymienić:38
- Brak standaryzacji w ustalaniu przypadków i dokładności diagnostycznej, np. stosowanie różnych definicji i algorytmów kodowania
- Różnice w pomiarze wykorzystania usług zdrowotnych, jakości, dostępu i kosztów
- Heterogeniczne podejścia do oceny wpływu drgawek na stan zdrowia i jakość życia
- Wyzwania w identyfikacji i rekrutacji świadczeniodawców opieki zdrowotnej i osób z drgawkami do udziału w projektach nadzoru i badawczych
Określenie aktualnych i dokładnych szacunków częstości występowania i chorobowości drgawek wymaga identyfikacji osób w populacji, które mają drgawki, i określenia, kiedy rozwinęły one to zaburzenie. Nadzór nad drgawkami dąży do kompletnego ustalenia osób z drgawkami39.
Niedoszacowanie lub przeszacowanie liczby osób z drgawkami w populacji może wystąpić z wielu powodów. Stosowanie różnych definicji drgawek prowadzi do tego, że niektóre badania obejmują przypadki, których inne badania by nie uwzględniły, co zwiększa potencjał niedoszacowania lub przeszacowania częstości występowania i chorobowości drgawek i uniemożliwia badaczom porównywanie danych między ośrodkami i badaniami40.
Trendy i perspektywy w epidemiologii drgawek
Globalne trendy w występowaniu drgawek
Na świecie różnice w występowaniu drgawek wynikają z różnic w czynnikach takich jak częstość występowania infekcji (takich jak zapalenie opon mózgowych, malaria lub neurocysticerkoza), dostęp do opieki zdrowotnej, choroby zakaźne, czynniki społeczno-ekonomiczne, predyspozycje genetyczne, wskaźniki urazów i wzorce stylu życia41.
Chorobowość padaczki w krajach o wysokich dochodach mieści się w przedziale od 4 do 10 na 1000 osób, co czyni ją jednym z najbardziej rozpowszechnionych stanów neurologicznych42. W krajach o niskich i średnich dochodach wskaźnik ten może wynosić nawet 139 na 100 000 mieszkańców43.
Według danych z Światowej Organizacji Zdrowia (WHO), około 50 milionów ludzi na całym świecie jest dotkniętych padaczką, a każdego roku diagnozuje się około 5 milionów nowych przypadków4445. W krajach o niskich dochodach około trzech czwartych osób z padaczką może nie otrzymywać potrzebnego leczenia. Jest to określane jako luka w leczeniu46.
Badania wykazały, że około 80% osób z padaczką mieszka w krajach o niskich i średnich dochodach, gdzie luka w leczeniu znacząco przyczynia się do globalnego obciążenia padaczką. Do 90% przypadków padaczki w tych regionach jest nieleczonych lub niedoleczonych, z powodu takich czynników jak ograniczone zasoby opieki zdrowotnej, przekonania kulturowe, stygmatyzacja społeczna i preferencyjne stosowanie tradycyjnych metod leczenia47.
Nowe perspektywy badawcze
Rozumienie epidemiologii drgawek ma kluczowe znaczenie dla identyfikacji populacji zagrożonych, wdrażania środków zapobiegawczych i poprawy ogólnego zarządzania tym stanem. Najnowsze badania w tym obszarze przedstawiają nowe perspektywy, ujawniając nieoczekiwane luki w leczeniu w krajach o wysokich dochodach i bariery w terminowej diagnozie i leczeniu drgawek48.
W badaniu przeprowadzonym przez Vanderbilt University Medical Center, wykorzystującym dane EHR od ponad 500 000 pacjentów, w tym dorosłych z drgawkami czynnościowymi, padaczką, drgawkami czynnościowymi i padaczką oraz populacją kontrolną, badacze opracowali klinicznie zwalidowane algorytmy do badania chorób współistniejących i innych czynników związanych z drgawkami czynnościowymi49.
Wyniki potwierdziły, że znacznie więcej kobiet niż mężczyzn miało zaburzenia związane z drgawkami czynnościowymi. Badanie wykazało również silne związki między drgawkami czynnościowymi a PTSD, lękiem i depresją50.
Badacze odkryli również nowe związki z incydentami naczyniowo-mózgowymi. Drgawki czynnościowe były związane z większym ryzykiem wystąpienia przemijającego niedokrwienia mózgu, niedrożności tętnic mózgowych lub krwotoku wewnątrzczaszkowego51.
Drgawki jako marker innych chorób
Występowanie drgawek może być wskaźnikiem innych schorzeń neurologicznych. Udar jest najczęstszą identyfikowalną etiologią nabytej padaczki w krajach o wysokich dochodach52. Częstość występowania padaczki po udarze krwotocznym wynosi nieco ponad 12%53.
Ponadto, drgawki pourazowe stanowią istotne i często zauważalne powikłanie po uszkodzeniu naczyniowo-mózgowym z powodu zawału i krwotoku, które może wpływać na powrót do zdrowia po udarze i długoterminowe rokowanie54.
Kluczowe czynniki ryzyka obejmują rodzaj, lokalizację i nasilenie udaru, przy czym udary korowe i krwotoczne są bardziej podatne na wywoływanie drgawek55.
| Region | Chorobowość padaczki (na 1000 osób) | Zapadalność (na 100,000 osobolat) | Szczególne cechy demograficzne |
|---|---|---|---|
| Kraje o wysokich dochodach | 4-10 | 49 | Wyższe wskaźniki u dzieci i osób starszych |
| Kraje o niskich i średnich dochodach | Brak dokładnych danych | Do 139 | 80% światowej populacji z padaczką; luka w leczeniu do 90% |
| USA | 8.5 | 61-79.1 | 3 miliony dorosłych (1% populacji); 456,000 dzieci |
| Wielka Brytania | 10 | Brak dokładnych danych | 630,000 osób (1% populacji); 80 nowych diagnoz dziennie |
| Japonia | Brak dokładnych danych | Brak dokładnych danych | 893,673 przypadków padaczki w 2022 r. |
| Australia | 8.3 | Brak dokładnych danych | 1 na 120 osób; 70% kontrolowanych lekami przeciwdrgawkowymi |
| Afryka | 17.3 (dzieci) | 250 (dzieci) | Najwyższa zapadalność w Tanzanii (850/100,000); najniższa w Kenii (60/100,000) |
Implikacje dla zdrowia publicznego
Obciążenie systemów opieki zdrowotnej
Drgawki epileptyczne stanowią 1% przyjęć do szpitala i 3% wizyt na oddziałach ratunkowych56. Roczne bezpośrednie koszty na pacjenta z padaczką wynoszą ponad 11 000 USD, a koszty pośrednie przekraczają 3 000 USD57. W 2019 roku średnie roczne wydatki na opiekę zdrowotną związaną wyłącznie z padaczką i drgawkami wyniosły 24,5 miliarda dolarów w Stanach Zjednoczonych58.
Hospitalizacja była końcowym punktem 23% wizyt związanych z drgawkami, w porównaniu do 13% wizyt niezwiązanych z drgawkami59. Spośród pacjentów hospitalizowanych z powodu drgawek 31,6% przebywało na oddziale intensywnej terapii/NCCU, a 1,1% było intubowanych60.
Wśród szpitalnych pacjentów z drgawkami, drgawki są częste i zostały powiązane ze złymi wynikami klinicznymi. Szacuje się, że częstość występowania drgawek na oddziałach ratunkowych i oddziałach szpitalnych wynosi odpowiednio 2,05% i 4,85%. Wśród 1 359 891 unikalnych pacjentów (652 769 pacjentów ambulatoryjnych SOR i 702 122 pacjentów hospitalizowanych) z rozpoznaniem drgawek, średni wiek wynosił 57,95±18,58 lat, 50,6% stanowiły kobiety, 70,3% osoby rasy białej, 72,2% osoby pochodzenia niehiszpańskiego, a 53,8% było ubezpieczonych w Medicare61.
Disparytety w opiece nad pacjentami z drgawkami
Disparytety rasowe i etniczne w opiece zdrowotnej są udokumentowane w różnych warunkach, w tym w ambulatoryjnym leczeniu padaczki, ale dotychczas niewiele było doniesień o nierównościach w nagłej opiece nad pacjentami z drgawkami62.
W badaniu przeprowadzonym w Stanach Zjednoczonych zaobserwowano dysproporcje rasowe i etniczne w obrazowaniu neurologicznym pacjentów z drgawkami na oddziałach ratunkowych63. Wizyty były proporcjonalnie wyższe wśród pacjentów rasy czarnej niż wśród osób rasy białej64.
Również w Wielkiej Brytanii odnotowano istotne nierówności. Zgony u osób z padaczką wzrosły o 70% między 2001 a 2014 rokiem. Zgony występują średnio osiem lat wcześniej niż w przypadku reszty populacji. Raport Public Health England z 2018 roku wykazał również, że osoby z padaczką mają trzykrotnie większe prawdopodobieństwo śmierci z powodu swojego stanu, jeśli mieszkają w obszarze ubóstwa65.
Przy odpowiednim leczeniu ponad 60% osób z padaczką mogłoby całkowicie przestać mieć napady. Jednak neurologia jest znana z poważnego niedofinansowania w porównaniu z innymi usługami zdrowotnymi w Wielkiej Brytanii66.
Potrzeby w zakresie nadzoru i badań
Istnieje potrzeba bardziej kompleksowego, terminowego i dokładnego nadzoru nad drgawkami poprzez omówienie luk w obecnych danych, ocenę wyzwań pomiarowych i metodologicznych związanych z gromadzeniem danych oraz przegląd dostępnych źródeł danych67.
Obecnie zasoby i mechanizmy nadzoru nad drgawkami są nieadekwatne, a ulepszenia są konieczne, aby zwiększyć zrozumienie aspektów epidemiologicznych drgawek i zidentyfikować skuteczne działania w zakresie prewencji, opieki zdrowotnej i usług społecznościowych, a także edukacji i świadomości68.
Potrzebne są dodatkowe opisowe i analityczne badania występowania drgawek w różnorodnych społecznościach i populacjach USA, aby lepiej scharakteryzować wskaźniki zapadalności na drgawki, czynniki ryzyka i etiologie, typy i nasilenie, a także stany i niepełnosprawności związane z drgawkami69.
Populacyjne badania epidemiologiczne drgawek są ważne dla decydentów i świadczeniodawców opieki zdrowotnej, aby planować i zapewniać programy prewencyjne oraz odpowiednią opiekę i usługi dla osób dotkniętych tym problemem70.

- #1 Seizure – Wikipediahttps://en.wikipedia.org/wiki/Seizure
Seizures are relatively common neurological events, with an estimated lifetime risk of experiencing at least one seizure approaching 8-10% within the general population. […] In adults, the risk of seizure recurrence within the five years following a new-onset seizure is 35%; the risk rises to 75% in persons who have had a second seizure. […] In children, the risk of seizure recurrence within the five years following a single unprovoked seizure is about 50%; the risk rises to about 80% after two unprovoked seizures. […] In the United States in 2011, seizures resulted in an estimated 1.6 million emergency department visits; approximately 400,000 of these visits were for new-onset seizures. […] Global variations exist, with higher rates of seizures and epilepsy reported in regions with elevated prevalence of risk factors such as central nervous system infections, traumatic brain injury, and limited access to perinatal care. […] Seizures contribute significantly to the global burden of neurological disease, affecting individuals’ quality of life, social participation, and access to education and employment.
- #2 Seizure epidemiology and demographics – wikidochttps://www.wikidoc.org/index.php/Seizure_epidemiology_and_demographics
It is estimated that 11% of the population experience a seizure in their life compared to the estimation of 3% for epilepsy. […] In the US, seizure is estimated to account for 1 million or 1% of emergency department (ED) visits annually. […] The incidence of acute symptomatic seizures is estimated to be 39 cases per 100,000 individuals in the US. […] Acute symptomatic seizures have the highest incidence among infants and small children, followed by those older than 75, and the lowest incidence among those between 25 to 34 years. […] Individuals of the African American race are more likely to have seizure-related ED visits compared to Whites. […] Males are more affected by seizures than females. […] The male to female ratio of a seizure-related ED visit is approximately 1.4 to 1. […] The male to female ratio of acute symptomatic seizures on a population level (not in the ED setting) is approximately 1.85 to 1 (lifetime risk of 5.0% in males and 2.7% in females).

While epilepsy is a well-characterized disease, the majority of emergency department (ED) visits for seizure involve patients without known epilepsy. The epidemiology of seizure presentations and national patterns of management are unclear. The aim of this investigation was to characterize ED visits for seizure in a large representative US sample and investigate any potential impact of race or ethnicity on management. […] Seizure accounts for 1 million ED visits annually [95% confidence interval (CI): 926,0001,040,000], or 1% of all ED visits in the USA. […] Seizures account for 1% of ED visits (1 million annually). Seizure accounts for higher proportions of ED visits among infants and toddlers, males and Blacks. Racial/ethnic disparities in neuroimaging and hospital admission merit further investigation.

Epidemiology […] It is estimated that 1 in 26 people will develop epilepsy during his or her lifetime. […] The incidence of single unprovoked seizures is 23-61 cases per 100,000 persons-years, while the incidence of acute symptomatic seizures is 29-39 cases per 100,000 population per year. […] Beghi et al attributed the variability to differences in methodology and definitions. […] The rates were similar in different geographic areas despite technical differences in the studies. […] Racial differences have not been studied, but there appears to be a small to moderate male preponderance of men studies of first adult seizures in most reports. […] However, in an early study, Annegers et al found a slight overall preponderance of women. […] Their etiologic categories were neurologic deficit from birth, remote symptomatic, and no known previous etiology.

The epidemiology of epilepsy is well developed, but the epidemiology of acute symptomatic seizures is less so. […] Disparities are known to exist in the treatment of epilepsy, but little is known about racial/ethnic determinants of care for acute symptomatic seizures. […] We estimate that seizures account for 1 million ED visits per year, or 1% of all ED visits, in the US. […] On a population basis, the rate of ED visits for seizure was 3.7 per 1,000 population per year. […] We confirmed our hypothesis that seizures account for a higher proportion of ED visits among males than among females. […] Visits were proportionally higher among Black patients than among Whites. […] We observed racial and ethnic disparities in neuroimaging of ED patients with seizure. […] Hospital admission was the endpoint of 23% of seizure visits, versus 13% for non-seizure visits. […] Racial and ethnic disparities in health care have been documented in a variety of settings, including in the outpatient management of epilepsy, but to our knowledge this is the first report of disparities in the emergency care of patients with seizure.
- #10 Seizure – Wikipediahttps://en.wikipedia.org/wiki/Seizure
Seizures are relatively common neurological events, with an estimated lifetime risk of experiencing at least one seizure approaching 8-10% within the general population. […] In adults, the risk of seizure recurrence within the five years following a new-onset seizure is 35%; the risk rises to 75% in persons who have had a second seizure. […] In children, the risk of seizure recurrence within the five years following a single unprovoked seizure is about 50%; the risk rises to about 80% after two unprovoked seizures. […] In the United States in 2011, seizures resulted in an estimated 1.6 million emergency department visits; approximately 400,000 of these visits were for new-onset seizures. […] Global variations exist, with higher rates of seizures and epilepsy reported in regions with elevated prevalence of risk factors such as central nervous system infections, traumatic brain injury, and limited access to perinatal care. […] Seizures contribute significantly to the global burden of neurological disease, affecting individuals’ quality of life, social participation, and access to education and employment.

People with epilepsy have increased mortality attributable to both seizure-related and unrelated causes (26, 27). It is estimated around 125,000 people worldwide succumb to epilepsy each year (28). The standardised mortality rates are 1.63.0 times higher than the general population in high-income countries (26), and up to 7.2 times higher in low- and middle-income countries (27). Uncontrolled seizures are known to be associated with increased mortality (29). Sudden unexpected death in epilepsy (SUDEP) and status epilepticus are the most important epilepsy-related causes of mortality (30). […] The incidence of epilepsy varies across different age groups and has a U-shaped bimodal distribution with the highest rates observed in young children and older adults (37). […] Understanding the epidemiology of epilepsy is crucial for identifying at-risk populations, implementing preventive measures, and improving the overall management of the condition. The articles in this Research Topic present novel perspectives on epilepsy. They unveil unexpected treatment gaps in high-income countries and barriers to timely epilepsy diagnosis and treatment. Additionally, the Topic highlights decreasing trends and research gaps in the mortality of epilepsy and status epilepticus.

Epilepsy is a chronic neurological disorder characterised by recurrent unprovoked seizures (1). It affects an estimated 50 million people worldwide with no socio-demographic boundary (2). Previous studies demonstrated the point prevalence of epilepsy to be between 4 and 10 per 1,000 persons, making it one of the most prevalent neurological conditions (28). The incidence rate of epilepsy is estimated around 5060 per 100,000 person-years (2, 5), and up to 8% of people having at least one seizure in their lifetime (9). […] Epileptic seizures account for 1% of hospital admissions and 3% of Emergency Department (ED) visits (14). The annual direct costs per patient with epilepsy is more than US$11,000, and indirect costs are more than US$3,000 (15, 16). […] Treatment gap in epilepsy has long been highlighted as a public health concern. Studies have shown that approximately 80% of people with epilepsy live in low- and middle-income countries, where the treatment gap contributes substantially to the global burden of epilepsy. Up to 90% of epilepsy in these areas is untreated or undertreated, due to factors such as limited healthcare resources, cultural beliefs, social stigma, and preferential use of traditional treatments (2123). This treatment gap is associated with poor health outcomes, life threatening conditions such as status epilepticus, and subsequently higher healthcare utilisation and healthcare costs. Recent studies also found that even in high-income countries, around a third of people with newly diagnosed epilepsy were not immediately treated (24, 25).

Epidemiology […] It is estimated that 1 in 26 people will develop epilepsy during his or her lifetime. […] The incidence of single unprovoked seizures is 23-61 cases per 100,000 persons-years, while the incidence of acute symptomatic seizures is 29-39 cases per 100,000 population per year. […] Beghi et al attributed the variability to differences in methodology and definitions. […] The rates were similar in different geographic areas despite technical differences in the studies. […] Racial differences have not been studied, but there appears to be a small to moderate male preponderance of men studies of first adult seizures in most reports. […] However, in an early study, Annegers et al found a slight overall preponderance of women. […] Their etiologic categories were neurologic deficit from birth, remote symptomatic, and no known previous etiology.

The occurrence of neonatal seizures may be the first, and perhaps the only, clinical sign of a central nervous system (CNS) disorder in the newborn infant. As such, seizures may indicate the presence of a potentially treatable etiology and should prompt an immediate evaluation to determine cause and to institute etiology-specific therapy. In addition, seizures themselves require emergency therapy, since they may adversely affect the infant’s homeostasis or contribute to further brain injury. […] […] Seizures occur more often in the neonatal period than at any other time of life; during this period, they most often occur within the first week of life. Reported incidence ranges from 1.5 to 5.5 per 1000 in newborns and may be even higher in premature infants. Seizure incidence varies with some specific risk factors. Occurrence increases with decreasing gestational age and birth weight, and with increasing acuity of illness. […] […] Most neonatal seizures (approximately 85 percent) are acute provoked seizures (previously called acute symptomatic seizures), occurring as a consequence of a specific identifiable etiology.

Epilepsy is a serious neurological condition that can affect anyone at any age and from any walk of life. There are 630,000 people with epilepsy living in the UK, around one in every 100 people. Every day, 80 people are diagnosed. […] One in every four people newly diagnosed with epilepsy is over the age of 65. One in 67 older people have epilepsy and this number is likely to keep increasing. […] There are around 60 different types of seizure and someone may have more than one type. Seizures vary depending on where in the brain they are happening. Some people remain aware throughout, while others can lose consciousness. […] Every year in the UK, around 1,000 people die from causes related to epilepsy. Half of these 1,000 deaths are from sudden unexpected death in epilepsy (SUDEP), when someone with epilepsy dies and no obvious cause of death can be found.

New findings suggest that unexplained seizures in older adults may be an early sign of Alzheimers disease. […] Seizures can be a symptom of advanced dementia, but they also occur in older adults with mild or no symptoms of cognitive decline. […] Yaffe and Keret using health records of just under 300,000 veterans in the Veterans Affairs health system found that those who had seizures with no known cause were twice as likely to develop dementia. […] The findings were published this week in JAMA Neurology. […] Yaffe and Keret posit that unexplained seizures may result from changes in the brain resulting from Alzheimers disease and other neurodegenerative forms of dementia that have yet to result in outward signs of dementia. […] We need more research before we can definitively say whats causing the seizures, Yaffe said, but these findings ought to encourage clinicians to follow these patients more closely for cognitive screening and possible interventions.

Determining timely and accurate incidence and prevalence estimates of epilepsy requires identifying individuals within a population who have epilepsy and determining when they developed the disorder. […] Surveillance of the epilepsies strives toward complete ascertainment of people with epilepsy. […] For epidemiologic studies, this is particularly important to reduce the chance of artificially increasing or decreasing the proportion of the study population with epilepsy. […] Under- or overestimating the number of people with epilepsy in a population can occur for many reasons. […] The use of varying definitions of epilepsy leads to some studies including cases that others would not, which increases the potential for under- or over-reporting epilepsy incidence and prevalence and prevents researchers from being able to compare data across sites and studies.

- #41 Seizures Epidemiology Forecast 2034https://www.expertmarketresearch.com/epidemiology-reports/seizures-epidemiology-forecast
The epidemiology of seizures varies between countries, owing to differences in factors such as the prevalence of infections (like meningitis, malaria, or neurocysticercosis), healthcare access, infectious diseases, socioeconomic factors, genetic predispositions, trauma rates, and lifestyle patterns. The Epilepsy Foundation states that around 1 in 100 people experienced a single unproved seizure or had an epilepsy diagnosis in the United States.
- #42 Editorial: Epidemiology of epilepsy and seizureshttps://pmc.ncbi.nlm.nih.gov/articles/PMC10911047/
Epilepsy is a chronic neurological disorder characterised by recurrent unprovoked seizures (1). It affects an estimated 50 million people worldwide with no socio-demographic boundary (2). Previous studies demonstrated the point prevalence of epilepsy to be between 4 and 10 per 1,000 persons, making it one of the most prevalent neurological conditions (28). The incidence rate of epilepsy is estimated around 5060 per 100,000 person-years (2, 5), and up to 8% of people having at least one seizure in their lifetime (9). […] Epileptic seizures account for 1% of hospital admissions and 3% of Emergency Department (ED) visits (14). The annual direct costs per patient with epilepsy is more than US$11,000, and indirect costs are more than US$3,000 (15, 16). […] Treatment gap in epilepsy has long been highlighted as a public health concern. Studies have shown that approximately 80% of people with epilepsy live in low- and middle-income countries, where the treatment gap contributes substantially to the global burden of epilepsy. Up to 90% of epilepsy in these areas is untreated or undertreated, due to factors such as limited healthcare resources, cultural beliefs, social stigma, and preferential use of traditional treatments (2123). This treatment gap is associated with poor health outcomes, life threatening conditions such as status epilepticus, and subsequently higher healthcare utilisation and healthcare costs. Recent studies also found that even in high-income countries, around a third of people with newly diagnosed epilepsy were not immediately treated (24, 25).

Epilepsy accounts for a significant proportion of the worlds disease burden, affecting around 50 million people worldwide. The estimated proportion of the general population with active epilepsy (i.e. continuing seizures or with the need for treatment) at a given time is between 4 and 10 per 1000 people. […] Globally, an estimated 5 million people are diagnosed with epilepsy each year. In high-income countries, there are estimated to be 49 per 100 000 people diagnosed with epilepsy each year. In low- and middle-income countries, this figure can be as high as 139 per 100 000. […] In low-income countries, about three quarters of people with epilepsy may not receive the treatment they need. This is called the treatment gap. […] In many low- and middle-income countries, there is low availability of antiseizure medicines. A recent study found the average availability of generic antiseizure medicines in the public sector of low- and middle-income countries to be less than 50%. This may act as a barrier to accessing treatment.
- #44 Epilepsy Monitoring Device Market Size, Forecasts Report 2034https://www.gminsights.com/industry-analysis/epilepsy-monitoring-device-market
The growth of the global epilepsy monitoring device market is highly attributed due to the increasing prevalence of epilepsy, which is a key catalyst that is accelerating the market growth. For instance, according to the data from the World Health Organization (WHO), in 2024, around 50 million people globally were affected. […] Moreover, WHO also reported that around 5 million new epilepsy diagnoses are made annually. […] Epilepsy monitoring devices play a significant role in accurately detecting abnormal brain activity and seizure classification. Therefore, as the prevalence of epilepsy conditions increases, so does the demand for these devices, which in turn necessities the need for epilepsy monitoring devices in order to ensure the safety and effective treatment, thereby fostering market growth.

People with epilepsy have increased mortality attributable to both seizure-related and unrelated causes (26, 27). It is estimated around 125,000 people worldwide succumb to epilepsy each year (28). The standardised mortality rates are 1.63.0 times higher than the general population in high-income countries (26), and up to 7.2 times higher in low- and middle-income countries (27). Uncontrolled seizures are known to be associated with increased mortality (29). Sudden unexpected death in epilepsy (SUDEP) and status epilepticus are the most important epilepsy-related causes of mortality (30). […] The incidence of epilepsy varies across different age groups and has a U-shaped bimodal distribution with the highest rates observed in young children and older adults (37). […] Understanding the epidemiology of epilepsy is crucial for identifying at-risk populations, implementing preventive measures, and improving the overall management of the condition. The articles in this Research Topic present novel perspectives on epilepsy. They unveil unexpected treatment gaps in high-income countries and barriers to timely epilepsy diagnosis and treatment. Additionally, the Topic highlights decreasing trends and research gaps in the mortality of epilepsy and status epilepticus.

Epidemiology of Seizures Amongst Patients Treated in U.S. Hospitals During 2016-2019: Among hospital patients, seizures are common and have been associated with poor clinical outcomes. Little is known about the current prevalence of seizures amongst U.S. inpatients (IP) and emergency department (ED) outpatients and their characteristics. This study aimed to estimate the prevalence and distribution of seizures within the hospital setting, understand the patient demographics, clinical characteristics, and patient journey. The prevalence of seizures in ED and IP was estimated to be 2.05% and 4.85%, respectively. Among the 1,359,891 unique patients (652,769 ED outpatients and 702,122 inpatients) with seizure diagnosis, mean age was 57.9518.58 years, 50.6% were female, 70.3% were White, 72.2% were non-Hispanic, and 53.8% Medicare insured. The most common seizure type was unspecified (49.1%), followed by other (42.8%, including 38.5% with convulsion), generalized (4.4%), partial onset/focal (2.9%) and multiple types (0.8%). Among seizure-associated visits, seizure was the primary diagnosis for 42% of ED visits compared to 17% of IP admits. Among seizure inpatients, 31.6% had ICU/NCCU stay, 1.1% were intubated; the most common comorbidities were hypertension (62.9%), congestive heart failure (15.0%), cardiac arrhythmia (14.0%), and dementia (12.7%). In terms of patient journey, 71.7% of seizure inpatients were admitted through ED or trauma center as referred by physician (90.7%). Approximately 25% of seizure inpatients were admitted directly to ICU ward, 6% were admitted to regular ward then admitted to ICU, and 69% were admitted to regular ward only. Less than 1% of seizure inpatients were discharged directly from ICU ward and majority as expired (45.1%). Fewer patients expired (5.5%) when discharged from regular ward. Conclusion: Seizure prevalence in ED and IP settings was higher than previously reported. Nearly a third of IP seizure patients had ICU stay and almost half of all seizures were unspecified. The overall in-hospital mortality rate among IP seizure patients is high.

Public health surveillance systems provide public health agencies, health care providers, policy makers, and the general public with critically important information on the health of people in the United States. […] This chapter describes the need for more comprehensive, timely, and accurate epilepsy surveillance by discussing gaps in current data, assessing the measurement and methodological challenges of collecting data, and reviewing available data sources. […] Epilepsy surveillance data inform all of the other chapters of this report. However, current epilepsy surveillance resources and mechanisms are inadequate, and improvements are necessary to increase understanding of the epidemiologic aspects of epilepsy and to identify effective action in prevention, health care, and community services, as well as education and awareness.

Additional descriptive and analytic studies of epilepsy occurrence in diverse U.S. communities and populations are needed to better characterize epilepsy incidence rates, risk factors and etiologies, and types and severity, as well as epilepsy-associated conditions and disabilities. […] Population-based epidemiological studies of epilepsy are important for policymakers and health-care providers to plan and provide prevention programs and appropriate care and services for those affected. […] The findings in this study regarding inadequate seizure control by medications might partly be a result of limited knowledge of current diagnostic and treatment standards for the care of epilepsy among certain groups of health care professionals.
