Choroba neuronu ruchowego (chnr)
Epidemiologia
Choroba neuronu ruchowego (CHNR) to rzadkie, postępujące schorzenie neurodegeneracyjne obejmujące neurony ruchowe w mózgu i rdzeniu kręgowym, z globalną zapadalnością wynoszącą średnio 1,9-2,6 przypadków na 100 000 osób rocznie oraz chorobowością około 4,5-6 na 100 000. W Europie zapadalność jest wyższa (ok. 2,6/100 000), a w krajach azjatyckich niższa (0,7-0,8/100 000). Występują znaczące różnice regionalne, np. w Wielkiej Brytanii chorobowość wynosi około 8,8/100 000, a w USA 5,2/100 000. CHNR częściej dotyka mężczyzn (stosunek 1,5-2:1) i osoby powyżej 50. roku życia, ze szczytem zapadalności między 70 a 79 rokiem życia. Najczęstszą formą jest ALS (ok. 90% przypadków), a pozostałe to PLS, PMA i HSP. Czynniki ryzyka obejmują płeć męską, wiek, predyspozycje genetyczne oraz potencjalne narażenia środowiskowe, takie jak chemikalia rolnicze, palenie tytoniu czy służba wojskowa. Warto zauważyć, że wyższy wskaźnik masy ciała (BMI ≥30 kg/m²) wiąże się z 20% niższym ryzykiem CHNR.
Epidemiologia Choroby Neuronu Ruchowego (CHNR)
Choroba neuronu ruchowego (CHNR) to rzadkie, postępujące, degeneracyjne schorzenie neurologiczne dotyczące neuronów motorycznych mózgu i rdzenia kręgowego. Częstość występowania CHNR na świecie różni się w zależności od regionu geograficznego, populacji oraz metod rejestracji przypadków. Dokładne zrozumienie epidemiologii tej choroby jest kluczowe dla planowania opieki zdrowotnej, identyfikacji czynników ryzyka oraz prowadzenia badań klinicznych.12
Zapadalność i chorobowość globalna
Globalna zapadalność (liczba nowych przypadków) na CHNR wynosi średnio 1,9-2,6 przypadków na 100 000 osób rocznie. Chorobowość (liczba osób chorujących w danym momencie) szacuje się na około 4,5-6 przypadków na 100 000 populacji. Dane te różnią się jednak znacząco między poszczególnymi regionami świata.34
W Europie zapadalność na CHNR jest wyższa niż globalnie i wynosi około 2,6 przypadków na 100 000 osób rocznie, a chorobowość sięga 7,9 na 100 000 mieszkańców. W krajach azjatyckich, szczególnie w Azji Wschodniej i Południowej, zapadalność jest niższa i wynosi odpowiednio około 0,8 i 0,7 przypadków na 100 000 osób rocznie.56
Warto podkreślić, że około 80% badań epidemiologicznych dotyczących CHNR przeprowadzono w Europie i Stanach Zjednoczonych, głównie wśród osób pochodzenia północnoeuropejskiego. Istnieje zatem znacząca luka w danych epidemiologicznych dotyczących innych części świata, w tym Afryki, części Azji, Indii, Rosji i Ameryki Południowej.7
Zapadalność i chorobowość w wybranych krajach
W Wielkiej Brytanii zapadalność na CHNR wynosi 2,6 przypadków na 100 000 kobiet i 3,9 na 100 000 mężczyzn rocznie. Szacuje się, że w UK choroba dotyka do 5000 dorosłych w dowolnym momencie, co daje chorobowość około 8,8 na 100 000 osób. Zidentyfikowano również wyższy wskaźnik chorobowości w Walii, szczególnie w obszarze Aneurin Bevan University Health Board (12,1/100 000).8910
W Stanach Zjednoczonych w 2015 roku chorobowość CHNR wynosiła 5,2 na 100 000 osób, z wyższymi wskaźnikami u osób białych, mężczyzn i osób powyżej 60 roku życia. Wskaźniki różniły się również regionalnie – najwyższe były na Środkowym Zachodzie (5,5/100 000), a najniższe na Zachodzie (4,4/100 000).11
W Australii, według raportu Deloitte Access Economics z 2015 roku, żyło około 2094 osób z CHNR, z chorobowością 8,7 na 100 000 mieszkańców (1 na 11 434 Australijczyków). Każdego dnia diagnozowane są średnio dwie nowe osoby, a dwie umierają z powodu tej choroby.1213
Szwecja odnotowała wzrost zapadalności na CHNR w ostatnich dwóch dekadach. We wczesnych latach 2000 surowa zapadalność wynosiła 3,5-3,7 na 100 000 osób-lat, następnie wzrosła do 4,0-4,6 od 2008 roku. Aktualnie średnia surowa zapadalność wynosi 4,1 na 100 000 osób-lat (3,5 dla kobiet i 4,7 dla mężczyzn), co jest wyższe niż wcześniej raportowana średnia europejska (2,0-2,3/100 000).14
W Nowej Zelandii zapadalność na CHNR jest wyższa niż średnia światowa – około 3 przypadków na 100 000 osób rocznie (w porównaniu do 2/100 000 globalnie). Co roku diagnozuje się tam średnio 144 nowe przypadki, a około 400 osób żyje z chorobą. Przyczyna wyższej zapadalności w Nowej Zelandii pozostaje niewyjaśniona.15
Geograficzne skupiska podwyższonej zapadalności
Zidentyfikowano kilka regionów na świecie z wyjątkowo wysoką zapadalnością na CHNR:1617
- Półwysep Kii w Japonii – gdzie tradycyjnie wykorzystywane są nasiona sagowca (cycad) jako lekarstwo
- Zachodnia Nowa Gwinea
- Wyspa Guam na Pacyfiku – gdzie wśród rdzennych mieszkańców Chamorro występuje specjalna forma CHNR zwana „kompleksem ALS-PD-demencja z Guam” lub „lytico bodig”
- Region Riverina w Nowej Południowej Walii (Australia) – gdzie według doniesień CHNR występuje około trzy razy częściej niż w innych regionach Australii
W tych regionach częstość występowania CHNR była historycznie 50-100 razy wyższa niż w pozostałej części świata, choć od lat 60. XX wieku obserwuje się spadek. Przyczyny tego zjawiska pozostają niejasne, choć sugerowano związek z dietą obejmującą nasiona sagowca lub spożywanie nietoperzy, które jedzą te nasiona.2021
W przypadku regionu Riverina w Australii podejrzewa się związek z narażeniem na chemikalia rolnicze. Utworzono tam pierwsze w Australii centrum nadzoru nad CHNR, które ma zbierać dane pacjentów w celu określenia przyczyn choroby i wyjaśnienia jej wysokiego rozpowszechnienia w tym regionie.2223
Ryzyko zachorowania w ciągu życia
Szacowane ryzyko zachorowania na CHNR w ciągu życia (lifetime risk) różni się w zależności od populacji i płci. Dla populacji europejskiej wynosi ono około 1:350 dla mężczyzn i 1:400-500 dla kobiet. W Wielkiej Brytanii ryzyko zachorowania w ciągu życia szacuje się na 1:300 (3,3 na 1000).242526
Bardziej szczegółowe badanie z Wielkiej Brytanii, uwzględniające konkurujące przyczyny zgonu, określiło ryzyko zachorowania na CHNR między 50 a 75 rokiem życia na 1:472 (2,1 na 1000) dla kobiet i 1:350 (2,9 na 1000) dla mężczyzn. Inne badanie oszacowało, że 1 na 575 kobiet prawdopodobnie zachoruje między 50 a 75 rokiem życia.2728
Globalnie, ryzyko zachorowania na ALS/CHNR w ciągu życia szacowane jest na 1:300 (3,3 na 1000), choć wartość ta może różnić się między populacjami.2930
Różnice demograficzne w zapadalności
Wiek
CHNR może wystąpić u dorosłych w każdym wieku, jednak znacząco częściej dotyka osoby powyżej 50 roku życia. Zapadalność rośnie wraz z wiekiem, osiągając szczyt między 70 a 79 rokiem życia. Średni wiek zachorowania na sporadyczną postać choroby wynosi 58-65 lat.313233
Badanie z Wielkiej Brytanii wykazało, że zapadalność specyficzna dla wieku wzrasta od 1,9 (95% CI 1,3-2,7) na 100 000 kobiet w wieku 50-54 lat do 12,5 (95% CI 10,2-15,3) na 100 000 kobiet w wieku 70-74 lat.34
Zapadalność spada dramatycznie po 80 roku życia. Przyczyna tego spadku nie jest w pełni wyjaśniona. Jedną z hipotez jest możliwość, że osoby dożywające 80 lat mogą nie być genetycznie podatne na rozwój CHNR. Alternatywnie, CHNR u osób starszych może pozostawać niezdiagnozowana z powodu chorób współistniejących, trudności w dostępie do neurologa lub szybkiego zgonu z powodu agresywnej formy choroby.35
W ostatnich latach obserwuje się niepokojący trend w niektórych regionach – zwiększoną liczbę przypadków CHNR u młodszych osób, diagnozowanych w czwartej dekadzie życia, podczas gdy wcześniej choroba ta występowała głównie w piątej lub szóstej dekadzie.36
Płeć
CHNR częściej dotyka mężczyzn niż kobiety, ze stosunkiem zachorowań mężczyzn do kobiet wynoszącym około 1,5-2:1. Różnica ta jest bardziej wyraźna w przypadkach sporadycznych niż rodzinnych.373839
Interesującym zjawiskiem jest zróżnicowanie w zależności od typu początkowego CHNR – ALS z początkiem opuszkowym (bulbar onset) jest częstszy u kobiet, natomiast ALS z początkiem rdzeniowym (spinal onset) dominuje u mężczyzn. Ta różnica w dystrybucji fenotypów między płciami częściowo tłumaczy wyższe ryzyko zachorowania u mężczyzn.4041
Rasa i pochodzenie etniczne
CHNR może dotykać osoby wszystkich ras i pochodzenia etnicznego, jednak badania wskazują na różnice w zapadalności między grupami rasowymi. W Stanach Zjednoczonych w 2015 roku chorobowość u osób białych wynosiła 5,4 na 100 000, natomiast u osób czarnoskórych – 2,3 na 100 000.42
Osoby pochodzenia europejskiego mają wyższą zapadalność na CHNR w porównaniu do osób pochodzenia afrykańskiego, azjatyckiego czy latynoamerykańskiego. Najniższą zapadalność obserwuje się w społecznościach Azji Południowej i Wschodniej (poniżej 1 na 100 000 osób).4344
Finlandia wyróżnia się wyjątkowo wysoką zapadalności na CHNR – niemal dwukrotnie wyższą niż w innych populacjach europejskich, co może sugerować wpływ czynników genetycznych specyficznych dla tej populacji.45
Rodzaje CHNR i ich epidemiologia
CHNR obejmuje grupę schorzeń, z których najczęstszym jest stwardnienie zanikowe boczne (ALS) stanowiące około 90% wszystkich przypadków. Inne rodzaje CHNR to: pierwotne stwardnienie boczne (PLS), postępujący zanik mięśni (PMA) oraz dziedziczne paraparazy spastyczne (HSP).4647
Postępujący zanik mięśni (PMA) stanowi 2,5-11% przypadków CHNR, z zapadalności około 0,02 na 100 000 osób, co czyni go znacznie rzadszą formą choroby.48
Częstość występowania pierwotnego stwardnienia bocznego (PLS) jest trudna do określenia ze względu na rzadkość występowania i znaczne nakładanie się z ALS.49
Częstość występowania dziedzicznych paraparaz spastycznych (HSP) różni się w zależności od regionu. W Irlandii chorobowość czystej autosomalnej dominującej HSP wynosi 1,17/100 000, podczas gdy w południowo-wschodniej Norwegii szacuje się ją na 7,4/100 000.50
Czynniki ryzyka
Główne znane czynniki ryzyka CHNR to: płeć męska, wiek powyżej 50 lat oraz predyspozycje genetyczne. Większość przypadków CHNR (90-95%) występuje sporadycznie, bez znanej przyczyny. Około 5-10% przypadków stanowią formy rodzinne (dziedziczne), związane z mutacjami genetycznymi.515253
Prowadzone są badania nad potencjalnymi środowiskowymi czynnikami ryzyka CHNR. Wśród nich wymienia się:5455
- Narażenie na chemikalia rolnicze – szczególnie w regionach o intensywnym rolnictwie
- Narażenie na silny wstrząs elektryczny prowadzący do śpiączki
- Palenie tytoniu – badania wykazały około 20% wyższe ryzyko CHNR u osób palących
- Służba wojskowa – francuskie badania wykazały o 16% wyższą zapadalność na CHNR wśród personelu wojskowego płci męskiej
- Uprawianie sportów wodnych w zanieczyszczonych zbiornikach
Interesującym odkryciem jest związek między masą ciała a ryzykiem CHNR. Badanie z Wielkiej Brytanii wykazało istotną statystycznie tendencję do zmniejszania ryzyka CHNR wraz ze wzrostem wskaźnika masy ciała (BMI). Osoby otyłe (BMI ≥30 kg/m²) miały o 20% niższe ryzyko CHNR w porównaniu do osób o normalnej masie ciała (BMI 20-25 kg/m²).59
Nadzór i rejestry CHNR
Ze względu na rzadkość występowania CHNR, kompleksowe rejestry pacjentów są niezbędne do prowadzenia wiarygodnych badań epidemiologicznych, identyfikacji czynników ryzyka oraz oceny skuteczności interwencji terapeutycznych.6061
Istniejące rejestry i systemy nadzoru
W różnych krajach funkcjonują specjalistyczne rejestry gromadzące dane dotyczące pacjentów z CHNR:6263
- Australijski Rejestr MND – utworzony w 2004 roku w celu gromadzenia i analizy danych pacjentów z CHNR w Australii
- Konsorcjum Genomiki Systemów Sporadycznego ALS Australia (SALSA-SGC) – utworzone w 2015 roku, zbiera spójne dane kliniczne i próbki biologiczne z klinik w całej Australii
- Rejestr MND Anglii, Walii i Irlandii Północnej – ma na celu zbieranie informacji o każdej osobie z CHNR w Wielkiej Brytanii
- CARE-MND (dawniej Szkocki Rejestr MND) – elektroniczna platforma do prospektywnych badań populacyjnych w Szkocji
- Irlandzka baza danych CHNR – zawiera dane wszystkich pacjentów z diagnozą CHNR w Republice Irlandii, co pozwala na szczegółowe badanie epidemiologii CHNR w czasie
- Sieć MND Południowej Walii – rejestruje dane kliniczne wszystkich pacjentów skierowanych do specjalistycznych klinik MND w południowej Walii
Powstają również nowe inicjatywy, jak pierwsze w Australii centrum nadzoru nad CHNR na Uniwersytecie Macquarie, które ma na celu zbieranie danych pacjentów, tworzenie szczegółowych map występowania choroby oraz badanie potencjalnych przyczyn środowiskowych.6768
Wyzwania w nadzorze nad CHNR
Mimo funkcjonowania rejestrów, nadzór nad CHNR napotyka na szereg wyzwań:6970
- CHNR nie jest chorobą rejestrowaną obowiązkowo w większości systemów opieki zdrowotnej, co utrudnia kompletne gromadzenie danych
- Dane są rozproszone w dokumentacji medycznej poszczególnych pacjentów i ich lekarzy prowadzących
- Diagnostyka CHNR może być trudna, szczególnie we wczesnych stadiach, co prowadzi do opóźnień w diagnozie (średnio 1,4 roku od pojawienia się objawów)
- Różnice w klasyfikacji i definicjach CHNR między krajami utrudniają porównywanie danych
Badania wykazują, że dokładność rutynowo zbieranych danych zdrowotnych w identyfikacji przypadków CHNR jest wystarczająca do prowadzenia dużych prospektywnych badań epidemiologicznych, zwłaszcza w krajach wysoko rozwiniętych. Wartość predykcyjna dodatnia (PPV) kodowania CHNR w tych zbiorach danych waha się od 55% do 92%, a w większości przypadków przekracza 80%.73
Przyszłość nadzoru nad CHNR
Rozwój technologii i zwiększona świadomość znaczenia rejestrów medycznych prowadzi do tworzenia nowych inicjatyw mających na celu poprawę nadzoru nad CHNR:7475
- Wykorzystanie zaawansowanych metod analizy przestrzennej do mapowania przypadków CHNR i identyfikacji skupisk geograficznych
- Integracja danych klinicznych z informacjami środowiskowymi
- Zastosowanie sztucznej inteligencji i uczenia maszynowego do odkrywania genetycznych czynników ryzyka CHNR
- Tworzenie platform do kompleksowych badań klinicznych, takich jak platforma badań klinicznych MND-SMART w Wielkiej Brytanii
W przyszłości, dokładniejsze dane nadzoru mogą pomóc w identyfikacji i modyfikacji środowiskowych czynników ryzyka CHNR, co potencjalnie mogłoby prowadzić do opracowania strategii profilaktycznych.78
Trendy czasowe w epidemiologii CHNR
Obserwacje epidemiologiczne z ostatnich dekad wskazują na pewne trendy w występowaniu CHNR, które mogą mieć istotne implikacje dla planowania opieki zdrowotnej i badań nad tą chorobą.7980
Wzrost zapadalności i chorobowości
W wielu krajach odnotowuje się wzrost liczby przypadków CHNR:8182
- W Szwecji zapadalność wzrosła z 3,5-3,7 na 100 000 osób-lat na początku lat 2000 do ponad 4 na 100 000 osób-lat po 2008 roku
- W Szkocji dane z rejestru CARE-MND sugerują wzrost zapadalności o 36%, co może być częściowo związane z poprawą usług neurologicznych
- W Australii w ciągu ostatnich 30 lat odnotowano wzrost liczby przypadków CHNR, a CHNR jako przyczyna zgonu wzrosła o 250%, z 1 na 500 zgonów do 1 na 200
Globalne prognozy wskazują, że liczba przypadków CHNR na świecie wzrośnie z 222 801 w 2015 roku do 376 674 w 2040 roku, co stanowi wzrost o 69%. Wzrost ten będzie w dużej mierze spowodowany starzeniem się populacji światowej, zwłaszcza w krajach rozwijających się.85
Zmiany w charakterystyce demograficznej
Obserwuje się również zmiany w charakterystyce demograficznej osób z CHNR:86
- W niektórych regionach, jak Australia, odnotowuje się zwiększoną liczbę przypadków CHNR u młodszych osób, diagnozowanych w czwartej dekadzie życia
- W rejonach o potencjalnym narażeniu na czynniki środowiskowe, takich jak region Riverina w Australii, obserwuje się nie tylko więcej przypadków, ale również młodszy wiek zachorowania
Część wzrostu zapadalności może być związana ze zmianami demograficznymi, takimi jak starzenie się populacji. Na przykład, w Szwecji średni wiek wzrósł z 40,6 lat w 2002 roku do 41,6 lat w 2021 roku, co mogło przyczynić się do zwiększenia liczby przypadków CHNR.88
Potencjalne przyczyny zmian epidemiologicznych
Istnieje kilka potencjalnych wyjaśnień obserwowanych trendów w epidemiologii CHNR:8990
- Poprawa diagnostyki i świadomości – lepszy dostęp do specjalistycznych usług neurologicznych i zwiększona świadomość CHNR wśród lekarzy
- Starzenie się populacji – wyższy odsetek osób w wieku podwyższonego ryzyka CHNR
- Czynniki środowiskowe – zwiększone narażenie na potencjalne czynniki ryzyka, takie jak chemikalia rolnicze
- Lepsze metody rejestracji i nadzoru – dokładniejsze zbieranie danych epidemiologicznych
Nadal jednak istnieje potrzeba dalszych badań w celu określenia, w jakim stopniu każdy z tych czynników przyczynia się do obserwowanych zmian w epidemiologii CHNR.93
Implikacje dla zdrowia publicznego
Znajomość epidemiologii CHNR jest kluczowa dla planowania opieki zdrowotnej i alokacji zasobów. Mimo że CHNR jest klasyfikowana jako choroba rzadka na podstawie jej chorobowości, ma znaczący wpływ na pacjentów, ich rodziny oraz systemy opieki zdrowotnej.9495
Organizacja opieki zdrowotnej
Ponieważ CHNR nie jest chorobą powszechną, pracownicy opieki zdrowotnej i społecznej mogą nie mieć doświadczenia w jej leczeniu. Dlatego ważne jest zapewnienie dostępu do specjalistów z odpowiednim doświadczeniem, zazwyczaj poprzez skierowanie do usług neurologicznych.96
Wielodyscyplinarne podejście do opieki (MDC) jest podstawą leczenia pacjentów z CHNR. Klinika wielodyscyplinarna zazwyczaj obejmuje neurologa, pielęgniarkę CHNR, fizjoterapeutę, terapeutów zajęciowych i logopedów. Badania wykazały, że podejście MDC może wydłużyć przeżycie od 7 do 24 miesięcy i zmniejszyć ryzyko zgonu o 45% w ciągu 5 lat.97
Zarówno American Academy of Neurology (AAN), jak i European Federation of Neurological Societies (EFNS) zalecają wielodyscyplinarną opiekę dla pacjentów z CHNR, uznając jej korzyści w poprawie przeżycia, zmniejszeniu powikłań medycznych i poprawie jakości życia pacjentów i ich opiekunów.98
Ekonomiczne obciążenie systemów opieki zdrowotnej
Według prognoz, rynek związany z CHNR ma odnotować znaczący wzrost w latach 2021-2028, z roczną stopą wzrostu (CAGR) na poziomie 7,0%. Wzrost ten jest napędzany przez rosnącą częstość występowania CHNR, starzenie się populacji, rosnące zapotrzebowanie na skuteczne i zaawansowane leczenie oraz rosnące wydatki na opiekę zdrowotną.99
Znajomość trendów demograficznych w umieralności związanej z CHNR ułatwia projektowanie odpowiednich usług w obszarach o większych potrzebach, umożliwiając wprowadzenie ścieżek opieki wspierających bardziej odpowiednią opiekę i lepszą jakość życia.100
Badania i rozwój
Dane epidemiologiczne są kluczowe dla prowadzenia badań nad CHNR, identyfikacji przyczyn choroby oraz opracowania skutecznych metod leczenia. Obecny brak leczenia dla CHNR jest w dużej mierze przypisywany faktowi, że przyczyna lub przyczyny choroby u większości osób nie są znane.101
Prowadzone są liczne inicjatywy badawcze mające na celu lepsze zrozumienie CHNR, w tym:102103
- Badania epidemiologiczne mające na celu identyfikację czynników ryzyka
- Badania genetyczne prowadzone w ramach międzynarodowych konsorcjów, takich jak International Project MinE Consortium
- Badania kliniczne testujące potencjalne metody leczenia, jak platforma badań klinicznych MND-SMART w Wielkiej Brytanii
- Badania nad biomarkerami progresji choroby, które mogą być wykorzystane jako miary wyników w badaniach klinicznych
Lepsze zrozumienie epidemiologii CHNR może pomóc w identyfikacji potencjalnych przyczyn środowiskowych, co z kolei mogłoby prowadzić do opracowania strategii profilaktycznych. Jak stwierdził profesor Dominic Rowe z Uniwersytetu Macquarie: „Jeśli zrozumiemy, co powoduje chorobę neuronu ruchowego ze środowiska, potencjalnie możemy jej zapobiec.”106

Motor neuron disease (MND) has been shown to approach 2 to 3 per 100,000 population, while a lower frequency (less than 1 per 100,000) of ALS has been demonstrated in the South and East Asian community. […] Approximately 10 to 15 percent of individuals with ALS have familial disease. […] The estimated lifetime risk of sporadic ALS is one in 400. […] While bulbar onset ALS has been shown to be more common in females, spinal onset illness has been shown to be common in males. […] Progressive muscular atrophy (PMA) represents 2.5 to 11 percent of cases with MND. With an incidence of 0.02 per 100,000 population, it is a much rarer form of the disease.

Motor neurone disease (MND) is a fatal, progressive, degenerative, neurological condition. MND occurs in all countries of the world. The impact of ALS/MND on the community is usually measured by the incidence and prevalence of the disease. Worldwide the incidence of ALS/MND is 2 per 100,000 of total population, while the prevalence is around 6 per 100,000 of total population. Research has found that the incidence is higher in people aged over 50 years. Although classified as a rare disease based on its prevalence it is estimated that approximately 140,000 new cases are diagnosed worldwide each year. The lifetime risk of developing ALS/MND has been calculated to be 1/300. […] In Australia, on average, each day two people die from MND and two people are diagnosed with MND. A Deloitte Access Economics report commissioned by MND Australia in 2015 estimated that there were 2,094 Australians living with MND, of whom 60% were male and 40% female. The overall prevalence rate was estimated to be 8.7 per 100,000 Australians, or 1 in 11,434 Australians, with the highest prevalence rate reported in males aged between 75 and 84 years.

- #4 ALS – Wikipediahttps://en.wikipedia.org/wiki/ALS
ALS is the most common motor neuron disease in adults and the third most common neurodegenerative disease after Alzheimer’s disease and Parkinson’s disease. Worldwide the number of people who develop ALS yearly is estimated to be 1.9 people per 100,000 per year, while the number of people who have ALS at any given time is estimated to be about 4.5 people per 100,000. In Europe, the number of new cases a year is about 2.6 people per 100,000, while the number affected is 79 people per 100,000. The lifetime risk of developing ALS is 1:350 for European men and 1:400 for European women. Men have a higher risk mainly because spinal-onset ALS is more common in men than women. The number of those with ALS in the United States in 2015 was 5.2 people per 100,000, and was higher in whites, males, and people over 60 years old. The number of new cases is about 0.8 people per 100,000 per year in East Asia and about 0.7 people per 100,000 per year in South Asia. About 80% of ALS epidemiology studies have been conducted in Europe and the United States, mostly in people of northern European descent. There is not enough information to determine the rates of ALS in much of the world, including Africa, parts of Asia, India, Russia, and South America. There are several geographic clusters in the Western Pacific where the prevalence of ALS was reported to be 50-100 times higher than in the rest of the world, including Guam, the Kii Peninsula of Japan, and Western New Guinea. The incidence in these areas has decreased since the 1960s; the cause remains unknown.

ALS is the most common motor neuron disease in adults and the third most common neurodegenerative disease after Alzheimer’s disease and Parkinson’s disease. Worldwide the number of people who develop ALS yearly is estimated to be 1.9 people per 100,000 per year, while the number of people who have ALS at any given time is estimated to be about 4.5 people per 100,000. In Europe, the number of new cases a year is about 2.6 people per 100,000, while the number affected is 79 people per 100,000. The lifetime risk of developing ALS is 1:350 for European men and 1:400 for European women. Men have a higher risk mainly because spinal-onset ALS is more common in men than women. The number of those with ALS in the United States in 2015 was 5.2 people per 100,000, and was higher in whites, males, and people over 60 years old.

National registries of patients with rare disease such as motor neurone disease (MND) can lead to more reliable epidemiological estimates. […] The South Wales MND Network records clinical data on all patients referred to the specialist MND clinics in south Wales and diagnosed with MND. […] There were 202 people with MND on the prevalence date, of whom 122 (60.4%) were male. The median time from onset to diagnosis was 1.4 years (interquartile range 0.92.4 years). Prevalence in the region was 8.8 per 100,000. This varied by local health board, with the highest prevalence seen in Aneurin Bevan University Health Board (12.1 per 100,000), and the lowest in Abertawe Bro Morgannwg University Health Board (7.0 per 100,000). Male:female ratio was similar for all local health boards (2=3.6, p=0.46). […] Our estimates of prevalence are in keeping with other European countries.

Motor neurone disease (MND) is a fatal, progressive, degenerative, neurological condition. MND occurs in all countries of the world. The impact of ALS/MND on the community is usually measured by the incidence and prevalence of the disease. Worldwide the incidence of ALS/MND is 2 per 100,000 of total population, while the prevalence is around 6 per 100,000 of total population. Research has found that the incidence is higher in people aged over 50 years. Although classified as a rare disease based on its prevalence it is estimated that approximately 140,000 new cases are diagnosed worldwide each year. The lifetime risk of developing ALS/MND has been calculated to be 1/300. […] In Australia, on average, each day two people die from MND and two people are diagnosed with MND. A Deloitte Access Economics report commissioned by MND Australia in 2015 estimated that there were 2,094 Australians living with MND, of whom 60% were male and 40% female. The overall prevalence rate was estimated to be 8.7 per 100,000 Australians, or 1 in 11,434 Australians, with the highest prevalence rate reported in males aged between 75 and 84 years.

Motor neuron diseases (MND), with amyotrophic lateral sclerosis constituting most cases, are rare conditions of unknown etiology. There have been reports of an increase in incidence during the latter half of the twentieth century in various Western countries, including Sweden. This study provides updated data on the incidence of MND in Sweden during the last 20 years. […] In the early 2000s, there was a crude incidence rate of 3.5-3.7 per 100,000 person-years, which then increased to 4.0-4.6 from 2008 onward. […] The incidence rate of MND in Sweden now seems to have surpassed 4 cases per 100,000 person-years. This is higher when compared to both other European countries and previous Swedish studies. […] Our findings showed an average crude incidence rate of 4.1 per 100,000 person-years for MND, during 2002-2021 in Sweden: 3.5 for females and 4.7 for males.

Motor neurone disease (MND) is the name given to a group of closely related disorders that affect the motor neurones. […] The incidence rate of MND in NZ is higher than the rest of the world – researchers are trying to find out why so we can change it. […] MND can affect adults at any age but most people diagnosed with MND are over the age of 40, with the highest incidence occurring between the ages of 50 and 70. […] In New Zealand an average of 144 people are diagnosed with MND every year about 3 in every 100,000 people. Internationally, the incidence of MND is much lower (approximately 2 in every 100,000 people). […] Approximately 400 people in New Zealand are living with MND. […] Each year MND causes the deaths of an average of 120 people in New Zealand. […] We don’t know why the rate of MND in New Zealand is higher than the international average.
- #33 Amyotrophic Lateral Sclerosis: Practice Essentials, Background, Pathophysiologyhttps://emedicine.medscape.com/article/1170097-overview
Approximately 5600 people in the United States are diagnosed with ALS each year. The annual incidence is 2-3 per 100,000 population; this is about equal to that of multiple sclerosis and 5 times higher than that of Huntington disease. It is estimated that as many as 18,000 Americans may have ALS at any given time. […] The lifetime risk for developing ALS for individuals aged 18 years has been estimated to be 1 in 350 for men and 1 in 420 for women. […] Age-adjusted European incidence data are similar to those for members of the US population who are of European descent. […] Most variability between countries has been attributed to different age composition or differences in case finding. […] More recent data, however, suggest that ethnic variability in disease incidence exists that may not be explained entirely by differences in case finding, with lower incidence in nonwhites or individuals of mixed ethnicity.

Motor neuron disease (MND) is a severe neurodegenerative disease with largely unknown etiology. Most epidemiological studies are hampered by small sample sizes and/or the retrospective collection of information on behavioural and lifestyle factors. […] 1.3 million women from the UK Million Women Study, aged 56 years on average at recruitment, were followed up for incident and/or fatal MND using NHS hospital admission and mortality data. […] During follow-up for an average of 92 years, 752 women had a new diagnosis of MND. Age-specific rates increased with age, from 19 (95% CI 13 27) to 125 (95% CI 102 153) per 100,000 women aged 50-54 to 70-74, respectively, giving a cumulative risk of diagnosis with the disease of 174 per 1000 women between the ages of 50 and 75 years. […] MND incidence in UK women rises rapidly with age, and an estimated 1 in 575 women are likely to be affected between the ages of 50 and 75 years.
- #35 ALS – Wikipediahttps://en.wikipedia.org/wiki/ALS
People of all races and ethnic backgrounds may be affected by ALS, but it is more common in whites than in Africans, Asians, or Hispanics. In the United States in 2015, the prevalence of ALS in whites was 5.4 people per 100,000, while the prevalence in blacks was 2.3 people per 100,000. The Midwest had the highest prevalence of the four US Census regions with 5.5 people per 100,000, followed by the Northeast (5.1), the South (4.7), and the West (4.4). The Midwest and Northeast likely had a higher prevalence of ALS because they have a higher proportion of whites than the South and West. […] ALS can affect people at any age, but the peak incidence is between 50 and 75 years and decreases dramatically after 80 years. The reason for the decreased incidence in the elderly is unclear. One thought is that people who survive into their 80s may not be genetically susceptible to developing ALS; alternatively, ALS in the elderly might go undiagnosed because of comorbidities (other diseases they have), difficulty seeing a neurologist, or dying quickly from an aggressive form of ALS. In the United States in 2015, the lowest prevalence was in the 18-39 age group, while the highest prevalence was in the 70-79 age group. Sporadic ALS usually starts around the ages of 58 to 63 years, while genetic ALS starts earlier, usually around 47 to 52 years. The number of ALS cases worldwide is projected to increase from 222,801 in 2015 to 376,674 in 2040, an increase of 69%. This will largely be due to the aging of the world’s population, especially in developing countries.

A new map has begun to build a picture of motor neuron disease (MND) in NSW, with the team at Australia’s first MND surveillance centre aiming to collect patient data to pinpoint the causes of the deadly neurodegenerative disease. […] Cluster: The NSW Riverina region has an unusually high incidence of MND, which experts say has likely links to the use of agricultural chemicals making their way into inland waterways. […] In that time, MND has increased as a cause of death in Australia by 250 per cent, up from one in 500 deaths to one in 200. […] We know MND cases are rising around the country, and we also seeing it more often in younger people, with an increase in patients being diagnosed in their forties when we used to see them in their fifties or sixties. […] Identifying clusters has long been stymied by the fact that MND is not a notifiable disease, Professor Rowe says.

- #41 ALS – Wikipediahttps://en.wikipedia.org/wiki/ALS
ALS is the most common motor neuron disease in adults and the third most common neurodegenerative disease after Alzheimer’s disease and Parkinson’s disease. Worldwide the number of people who develop ALS yearly is estimated to be 1.9 people per 100,000 per year, while the number of people who have ALS at any given time is estimated to be about 4.5 people per 100,000. In Europe, the number of new cases a year is about 2.6 people per 100,000, while the number affected is 79 people per 100,000. The lifetime risk of developing ALS is 1:350 for European men and 1:400 for European women. Men have a higher risk mainly because spinal-onset ALS is more common in men than women. The number of those with ALS in the United States in 2015 was 5.2 people per 100,000, and was higher in whites, males, and people over 60 years old. The number of new cases is about 0.8 people per 100,000 per year in East Asia and about 0.7 people per 100,000 per year in South Asia. About 80% of ALS epidemiology studies have been conducted in Europe and the United States, mostly in people of northern European descent. There is not enough information to determine the rates of ALS in much of the world, including Africa, parts of Asia, India, Russia, and South America. There are several geographic clusters in the Western Pacific where the prevalence of ALS was reported to be 50-100 times higher than in the rest of the world, including Guam, the Kii Peninsula of Japan, and Western New Guinea. The incidence in these areas has decreased since the 1960s; the cause remains unknown.

ALS Amyotrophic Lateral Sclerosismay be the best known and most common motor neuron disease (MND), but its not the only one. […] Motor neuron diseases are a category of neurologic disease that involve progressive degeneration of motor neurons. MNDs destroy motor neurons, which are the cells that control skeletal muscle activity such as walking, breathing, speaking, and swallowing. All MNDs cause muscle weakness that worsens over time, and many are fatal. […] MNDs are more common in men, and onset typically begins between age 50 and 70. The cause is usually unknown. About 5% to 7% of people who have a motor neuron disease have a hereditary type. […] The issue isnt motor neuron disease vs. ALS. After all, ALS is a motor neuron diseaseits the most common. But the MND category encompasses an array of diseases, including, among others, progressive bulbar palsy, primary lateral sclerosis, progressive muscular atrophy and spinal muscular atrophy.

The incidence of MND is approximately 15 out of 100,000 people. Men have a slightly higher incidence rate than women. Approximately 5,600 cases are diagnosed in the U.S. every year. By far the greatest risk factor is age, with symptoms typically presenting between the ages of 50-70. Cases under the age of 50 years are called „young onset MND”, whilst incidence rates appear to tail off after the age of 85. […] Tentative environmental risk factors identified so far include: exposure to severe electrical shock leading to coma, having served in the first Gulf War, and playing professional football (soccer). However, these findings have not been firmly identified and more research is needed. […] There are three „hot spots” of MND in the world. One is in the Kii peninsula of Japan, one amongst a tribal population in Papua New Guinea. Chamorro inhabitants from the island of Guam in the Pacific Ocean have an increased risk of developing a form of MND known as Guamanian ALS-PD-dementia complex or „lytico bodig”, although the incidence rate has declined over the last 50 years and the average age of onset has increased.

National registries of patients with rare disease such as motor neurone disease (MND) can lead to more reliable epidemiological estimates. […] The South Wales MND Network records clinical data on all patients referred to the specialist MND clinics in south Wales and diagnosed with MND. […] There were 202 people with MND on the prevalence date, of whom 122 (60.4%) were male. The median time from onset to diagnosis was 1.4 years (interquartile range 0.92.4 years). Prevalence in the region was 8.8 per 100,000. This varied by local health board, with the highest prevalence seen in Aneurin Bevan University Health Board (12.1 per 100,000), and the lowest in Abertawe Bro Morgannwg University Health Board (7.0 per 100,000).

The mortality rate is estimated to be 3.14 per 100,000 across the entire population, which was equivalent to 752 deaths due to MND in 2015. Approximately 55% of deaths occur in males. […] The global incidence of ALS varies between 1 and 2.6 cases per 100,000 people per year, with the average age of onset ranging from 54 to 67 years old. The prevalence of ALS increases with age, reaching 1/5000 among people aged 70-79 years old. […] The incidence of ALS is about 2 per 100,000 person-years, and the prevalence is about 5 per 100,000 persons. […] The Australian MND Registry was established in 2004 as a means to facilitate the collection and analysis of MND patient data in Australia. The goal of the registry is to improve patient care through continuous evaluation of patient management and associated outcomes, and by contributing to research.

Clinical Audit Research and Evaluation for Motor Neurone Disease (CARE-MND) (formerly the Scottish MND Register) is an electronic platform for prospective, population-based research in Scotland. We present the results of recent epidemiological analyses. […] Crude prevalence of MND in Scotland is 7.617.64/100,000 of the population. Direct age standardised incidence in 2015 was 3.42/100,000 (95% CI: 2.99 to 3.91); in 2016, 2.89/100,000 (95% CI: 2.50 to 3.34). […] Our data suggest a changing landscape of MND in Scotland, with a rise in incidence by 36%. This could be attributed to improved neurological services in Scotland. Incidence is also 67% higher than Northern European estimates, which perhaps reflects our robust ascertainment methods. However, further work using population CARE-MND data aims to determine if genetic or environmental variables account for these findings.

- #65 The epidemiology of MND – MND Research Bloghttps://mndresearch.blog/2021/11/04/the-epidemiology-of-mnd/
A total of 256 MND patients were identified between 2017-2019 from the Australian Motor Neurone Disease Registry. Based on the 2016 population of 1,676,653 persons, the estimated prevalence was 6.79 per 100,000 persons. These results indicate that the prevalence and incidence of MND in South Australia are high compared to global estimates. […] The incidence of MND in people of Bangladeshi, Indian and Pakistani ethnicity has not previously been reported. […] The current lack of treatment for MND is largely attributed to the fact that the cause, or causes, of most individuals disease is not known. […] Data collection in ALSrisc is ongoing but the data so far shows that average age at diagnosis is 65.9 years and the average delay in diagnosis is 1.4 years. The characteristics of ALSrisc cases are generally comparable to those of all ALS patients diagnosed in Stockholm during the same period according to the MND Quality Registry.

This thesis describes a series of studies examining aspects of the epidemiology of motor neuron disease (MND). The Republic of Ireland has a unique database of all patients diagnosed with MND which allows detailed study of MND epidemiology over time. Approximately 200-240 patients in Ireland have MND at any one time and 80 patients are diagnosed on a yearly basis. Data on over 1000 patients has been collected since 1993. […] The first part of this study aimed to update and reanalyse the Irish MND population data. In particular it was of interest to compare current incidence and prevalence data from a study published in 1999 to examine for changing population trends after introduction of new standards of care in nutritional and respiratory management of MND. […] We discovered relatively stable epidemiology in our MND population over the last decade with identical figures produced by the NI MND register. It would appear that new standards of care have not yet impacted life expectancy in the Irish MND population but further study is required in the future.

There is currently no data in Australia that systematically collects who has motor neurone disease, he said. […] Professor Rowe said the project aimed to back up current hypotheses about what causes MND. […] We strongly suspect, and in fact there’s increasing evidence not just from Australia but from around the world, that this disease is caused by triggers in the environment, he said. […] If we understand what’s causing motor neurone disease from the environment, potentially we can prevent it. […] Dr Jude said exposure to chemicals was common within the region as there were many farming communities. […] We think that the exposure to those environmental factors, or chemicals, or water quality, it’s very likely that the exposure happens a long time before the symptoms of MND start, he said. […] So really trying to nut out what the specific issues are is complicated because we’re dealing with a problem that’s coming later.

Motor neurone disease (MND) is a rare neurodegenerative condition, with poorly understood aetiology. […] We systematically evaluated the accuracy of such datasets in identifying MND cases. […] Thirteen eligible studies provided 13 estimates of PPV and five estimates of sensitivity. […] Diagnostic accuracy of routinely-collected health datasets is likely to be sufficient for identifying cases of MND in large-scale prospective epidemiological studies in high income country settings. […] Primary care datasets, particularly from countries with a widely-accessible national healthcare system, are potentially valuable data sources warranting further investigation. […] In this study we aimed to systematically review all studies that investigated the accuracy of routinely-collected health datasets in identifying MND cases by comparing coded information to a reference standard.

National registries of patients with rare disease such as motor neurone disease (MND) can lead to more reliable epidemiological estimates. […] The South Wales MND Network records clinical data on all patients referred to the specialist MND clinics in south Wales and diagnosed with MND. […] There were 202 people with MND on the prevalence date, of whom 122 (60.4%) were male. The median time from onset to diagnosis was 1.4 years (interquartile range 0.92.4 years). Prevalence in the region was 8.8 per 100,000. This varied by local health board, with the highest prevalence seen in Aneurin Bevan University Health Board (12.1 per 100,000), and the lowest in Abertawe Bro Morgannwg University Health Board (7.0 per 100,000). Male:female ratio was similar for all local health boards (2=3.6, p=0.46). […] Our estimates of prevalence are in keeping with other European countries. Future investigation into variation in MND prevalence may provide insights into underlying mechanisms of disease.

The accuracy of MND coding in these routinely-collected datasets therefore needs to be understood. […] There were thirteen estimates of PPV, eight based on hospital admissions data, one on hospital admissions and outpatient data combined, three on death data and one on primary care data. […] Reported PPVs ranged from 55%-92%; more than half of these (including over half of the total number of patients studied) were 80%. […] In the nine studies of hospital data, PPVs ranged from 55-92%. […] Primary care data appears to be a promising source of MND case ascertainment for prospective studies based in countries with universally-accessible primary health care. […] In general, PPV and sensitivity of routinely-collected health data in identifying MND cases are likely to be sufficient for many epidemiological studies investigating the determinants of MND.

Motor neuron diseases (MND), with amyotrophic lateral sclerosis constituting most cases, are rare conditions of unknown etiology. There have been reports of an increase in incidence during the latter half of the twentieth century in various Western countries, including Sweden. This study provides updated data on the incidence of MND in Sweden during the last 20 years. […] In the early 2000s, there was a crude incidence rate of 3.5-3.7 per 100,000 person-years, which then increased to 4.0-4.6 from 2008 onward. […] The incidence rate of MND in Sweden now seems to have surpassed 4 cases per 100,000 person-years. This is higher when compared to both other European countries and previous Swedish studies. […] Our findings showed an average crude incidence rate of 4.1 per 100,000 person-years for MND, during 2002-2021 in Sweden: 3.5 for females and 4.7 for males. This is a higher estimate compared to the previously reported European average of 2.0-2.3 per 100,000 person-years for ALS.

- #85 ALS – Wikipediahttps://en.wikipedia.org/wiki/ALS
People of all races and ethnic backgrounds may be affected by ALS, but it is more common in whites than in Africans, Asians, or Hispanics. In the United States in 2015, the prevalence of ALS in whites was 5.4 people per 100,000, while the prevalence in blacks was 2.3 people per 100,000. The Midwest had the highest prevalence of the four US Census regions with 5.5 people per 100,000, followed by the Northeast (5.1), the South (4.7), and the West (4.4). The Midwest and Northeast likely had a higher prevalence of ALS because they have a higher proportion of whites than the South and West. […] ALS can affect people at any age, but the peak incidence is between 50 and 75 years and decreases dramatically after 80 years. The reason for the decreased incidence in the elderly is unclear. One thought is that people who survive into their 80s may not be genetically susceptible to developing ALS; alternatively, ALS in the elderly might go undiagnosed because of comorbidities (other diseases they have), difficulty seeing a neurologist, or dying quickly from an aggressive form of ALS. In the United States in 2015, the lowest prevalence was in the 18-39 age group, while the highest prevalence was in the 70-79 age group. Sporadic ALS usually starts around the ages of 58 to 63 years, while genetic ALS starts earlier, usually around 47 to 52 years. The number of ALS cases worldwide is projected to increase from 222,801 in 2015 to 376,674 in 2040, an increase of 69%. This will largely be due to the aging of the world’s population, especially in developing countries.

Motor neurone disease (MND) is a fatal, progressive, degenerative, neurological condition. MND occurs in all countries of the world. The impact of ALS/MND on the community is usually measured by the incidence and prevalence of the disease. Worldwide the incidence of ALS/MND is 2 per 100,000 of total population, while the prevalence is around 6 per 100,000 of total population. Research has found that the incidence is higher in people aged over 50 years. Although classified as a rare disease based on its prevalence it is estimated that approximately 140,000 new cases are diagnosed worldwide each year. The lifetime risk of developing ALS/MND has been calculated to be 1/300. […] In Australia, on average, each day two people die from MND and two people are diagnosed with MND. A Deloitte Access Economics report commissioned by MND Australia in 2015 estimated that there were 2,094 Australians living with MND, of whom 60% were male and 40% female. The overall prevalence rate was estimated to be 8.7 per 100,000 Australians, or 1 in 11,434 Australians, with the highest prevalence rate reported in males aged between 75 and 84 years.

Motor Neurone Disease (MND) is a neurodegenerative condition affecting motor neurons in spinal cord and brainstem, leading to a reduced life expectancy. This study describes demographic trends in MND-associated mortality in the United States over a 20-year period. […] Data was extracted from the Centers for Disease Control and Prevention Wide-Ranging OnLine Data for Epidemiologic Research underlying cause of death database. All death certificates from 1999-2020 with MND (G12.2) recorded as the cause of mortality were extracted. Annual MND-associated crude mortality rates (CMR) and age-adjusted mortality rates (AAMR) per 100,000 persons with 95% confidence intervals (CI) were calculated. Joinpoint regression was used to calculate the annual trends in MND-associated mortality by calculating the annual percentage change.

MND affects up to 5,000 adults in the UK at any one time. There is a 1 in 300 risk of getting MND across a lifetime. It can affect adults of any age, but is more likely to affect people over 50. […] As motor neurone disease is not common, general health and social care professionals may not see many cases. This means it is important to seek out specialists who have appropriate experience in its treatment and care usually with referral to neurological services.
- #97 Supportive & palliative interventions in motor neurone disease: what we know from current literature? – Benjamin Cheng – Annals of Palliative Medicinehttps://apm.amegroups.org/article/view/17160/html
Although there is no cure for motor neurone disease (MND), the advent of supportive interventions including multidisciplinary care (MDC) has improved treatment interventions and enhanced quality of life (QOL) for MND patients and their carers. […] The multidisciplinary clinic typically involves a neurologist, MND nurse, physiotherapist, occupational and speech therapists. […] MDC approach is the mainstay for the management of patients with chronic neurological conditions such as multiple sclerosis, stroke, acquired brain injury, and MND. […] MDC is reported to prolong survival from 7 to 24 months, possibly further enhanced in patients with bulbar disease, while reducing the risk of death by 45% at 5 years. […] Both AAN and EFNS recommend MDC care setting for patients with MND, with the current EFNS guidelines recognizing the benefit of MDC approach in improving survival, reducing medical complications, and improving the QOL of patients and their caregivers.

- #101 The epidemiology of MND – MND Research Bloghttps://mndresearch.blog/2021/11/04/the-epidemiology-of-mnd/
A total of 256 MND patients were identified between 2017-2019 from the Australian Motor Neurone Disease Registry. Based on the 2016 population of 1,676,653 persons, the estimated prevalence was 6.79 per 100,000 persons. These results indicate that the prevalence and incidence of MND in South Australia are high compared to global estimates. […] The incidence of MND in people of Bangladeshi, Indian and Pakistani ethnicity has not previously been reported. […] The current lack of treatment for MND is largely attributed to the fact that the cause, or causes, of most individuals disease is not known. […] Data collection in ALSrisc is ongoing but the data so far shows that average age at diagnosis is 65.9 years and the average delay in diagnosis is 1.4 years. The characteristics of ALSrisc cases are generally comparable to those of all ALS patients diagnosed in Stockholm during the same period according to the MND Quality Registry.

There is currently no data in Australia that systematically collects who has motor neurone disease, he said. […] Professor Rowe said the project aimed to back up current hypotheses about what causes MND. […] We strongly suspect, and in fact there’s increasing evidence not just from Australia but from around the world, that this disease is caused by triggers in the environment, he said. […] If we understand what’s causing motor neurone disease from the environment, potentially we can prevent it. […] Dr Jude said exposure to chemicals was common within the region as there were many farming communities. […] We think that the exposure to those environmental factors, or chemicals, or water quality, it’s very likely that the exposure happens a long time before the symptoms of MND start, he said. […] So really trying to nut out what the specific issues are is complicated because we’re dealing with a problem that’s coming later.
