Choroba neuronu ruchowego (chnr)
Diagnostyka i diagnoza
Diagnostyka choroby neuronu ruchowego (ChNR) opiera się na ocenie klinicznej, badaniach elektrofizjologicznych (EMG, NCS), obrazowych (MRI, PET) oraz wykluczeniu innych schorzeń o podobnym obrazie klinicznym. Średni czas od pojawienia się pierwszych objawów do rozpoznania wynosi 10-18 miesięcy, co stanowi około jedną trzecią średniego czasu przeżycia. Kluczowe cechy diagnostyczne to postępujące osłabienie mięśniowe z objawami uszkodzenia górnego i dolnego neuronu ruchowego w co najmniej dwóch obszarach ciała, bez objawów czuciowych. Badania elektrofizjologiczne wykazują cechy ostrego i przewlekłego odnerwienia oraz reinerwacji mięśni. MRI służy głównie do wykluczenia innych patologii, natomiast badania genetyczne są wskazane u pacjentów z rodzinną historią choroby (5-10% przypadków). W diagnostyce różnicowej należy uwzględnić m.in. stwardnienie rozsiane, miastenię gravis, neuropatie obwodowe oraz guzy ośrodkowego układu nerwowego.
Diagnostyka choroby neuronu ruchowego (chnr)
Diagnostyka choroby neuronu ruchowego (chnr), znanej również jako motor neurone disease (MND), stanowi złożony i często długotrwały proces. Brak jednego specyficznego testu diagnostycznego sprawia, że rozpoznanie opiera się głównie na objawach klinicznych, wynikach badania neurologicznego oraz wykluczeniu innych schorzeń, które mogą wywoływać podobne objawy.12 Wczesne i prawidłowe rozpoznanie ma kluczowe znaczenie dla zapewnienia odpowiedniej opieki i możliwych interwencji terapeutycznych, które mogą wydłużyć przeżycie i poprawić jakość życia pacjentów.34
Wyzwania w procesie diagnostycznym
Diagnostyka chnr jest trudna z kilku powodów. Po pierwsze, choroba ta jest stosunkowo rzadka. Po drugie, wpływa na każdą osobę w inny sposób – nie istnieje jeden charakterystyczny objaw, który natychmiast sugerowałby to rozpoznanie. Początkowe objawy mogą być łagodne i niespecyficzne, często przypominające inne, częstsze schorzenia neurologiczne.56 Wiele osób doświadcza objawów przez miesiące lub nawet lata przed uzyskaniem ostatecznej diagnozy.7
Średni czas od wystąpienia pierwszych objawów do diagnozy wynosi około 10-18 miesięcy, co stanowi około jedną trzecią średniego czasu przeżycia od początku objawów.89 Ten opóźniony proces diagnostyczny może powodować znaczny dyskomfort psychiczny u pacjentów i negatywnie wpływać na zaufanie do dalszego prowadzenia leczenia.10
Kryteria diagnostyczne
Diagnostyka chnr opiera się głównie na kryteriach klinicznych, przy czym istotne jest stwierdzenie postępującego charakteru objawów.11 Chociaż istnieją formalne kryteria diagnostyczne dla chnr (np. zweryfikowane kryteria El Escorial), nie są one powszechnie stosowane w codziennej praktyce klinicznej.12 Światowa Federacja Neurologii (WFN) zaproponowała dalszą rewizję kryteriów w świetle postępów w technikach neurofizjologicznych, zalecając nadanie większego znaczenia wynikom badań neurofizjologicznych w diagnozowaniu chnr.13
Kluczowe cechy kliniczne sugerujące chnr obejmują postępujący charakter osłabienia mięśniowego, obecność objawów uszkodzenia górnego i dolnego neuronu ruchowego w więcej niż jednym obszarze ciała, przy braku objawów czuciowych.1415 Charakterystycznym obrazem klinicznym jest osłabienie i zanik mięśni z zachowaniem odruchów, co silnie sugeruje chnr do momentu wykluczenia innych przyczyn.16
Badania diagnostyczne w chorobie neuronu ruchowego
Badania elektrofizjologiczne
Badania elektrofizjologiczne stanowią kluczowy element diagnostyki chnr. Obejmują one elektromiografię (EMG) oraz badania przewodnictwa nerwowego (NCS).1718
Elektromiografia (EMG) to istotne badanie w diagnostyce chnr, określane czasem jako „test igłowy”, ponieważ wykorzystuje cienkie igły do rejestrowania naturalnie występujących impulsów elektrycznych w nerwach.19 EMG mierzy aktywność elektryczną w mięśniach i może wykryć nieprawidłowości wskazujące na uszkodzenie nerwów. Mięśnie, które utraciły unerwienie w wyniku chnr, wykazują charakterystyczny wzorzec.20 U pacjentów z chnr badanie EMG wykazuje cechy: (1) ostrego odnerwienia, które postępuje wraz z degeneracją neuronów ruchowych, oraz (2) przewlekłego odnerwienia i reinerwacji mięśni, gdy pozostałe neurony ruchowe próbują kompensować utracone neurony.21
Badania przewodnictwa nerwowego (NCS) polegają na analizie funkcji nerwowej poprzez elektryczną stymulację nerwów i rejestrację aktywności mięśniowej.22 Aplikuje się impuls elektryczny przez małą elektrodę na skórze, co pozwala zmierzyć szybkość, z jaką nerwy przewodzą sygnały elektryczne.23 Badanie to pomaga wykluczyć inne schorzenia, takie jak neuropatie, i dostarcza ważnych danych na temat stanu nerwów, co jest istotne dla odróżnienia chnr od innych chorób nerwowo-mięśniowych.24
Przezczaszkowa stymulacja magnetyczna (TMS) jest nieinwazyjną techniką oceniającą funkcjonalną integralność kory ruchowej i drogi korowo-rdzeniowej.25 Badanie to mierzy aktywność górnych neuronów ruchowych, a jego wyniki mogą pomóc w procesie diagnostycznym.26
Badania obrazowe
Rezonans magnetyczny (MRI) jest najczęściej stosowaną metodą obrazowania w diagnostyce chnr.27 Badanie to obejmuje umieszczenie pacjenta w cylindrycznym urządzeniu, które wykonuje wewnętrzne obrazy ciała.28 Chociaż MRI nie może bezpośrednio zdiagnozować chnr, ponieważ uszkodzenia spowodowane tą chorobą nie są widoczne w tym badaniu, jest ono szczególnie przydatne do wykluczenia innych stanów neurologicznych, takich jak stwardnienie rozsiane, guzy mózgu, udar mózgu, choroba Parkinsona, choroba Alzheimera oraz zmiany strukturalne, które mogłyby powodować podobne objawy.2930 MRI może również wykryć uszkodzenia kręgosłupa i mózgu.31
Pozytonowa tomografia emisyjna (PET), często łączona z tomografią komputerową (CT), jest coraz częściej wykorzystywana w badaniach i diagnostyce chnr.32
Badania laboratoryjne
Badania krwi nie mogą bezpośrednio diagnozować chnr, ale mogą być pomocne w wykluczeniu innych stanów.33 Mogą one wykryć substancję zwaną kinazą kreatynową (CK) we krwi, która jest czasami podwyższona w chnr, ale również w innych schorzeniach.34 Badania krwi mogą być również wykonywane w celu poszukiwania dowodów uszkodzenia mięśni, przyczyn zapalenia w rdzeniu kręgowym (takich jak poziom witaminy B12) lub w celu znalezienia dowodów wspierających uszkodzenie nerwów ruchowych (takich jak przeciwciała anty-gangliozydy).35
Nakłucie lędźwiowe (punkcja lędźwiowa) polega na pobraniu próbki płynu mózgowo-rdzeniowego do analizy. Chociaż nie można za pomocą tego badania zdiagnozować chnr, może ono dostarczyć informacji na temat innych możliwych przyczyn objawów pacjenta, takich jak infekcje lub stany zapalne rdzenia kręgowego i mózgu.3637
Badania genetyczne
W około 5-10% przypadków chnr występuje rodzinna historia choroby, co wskazuje, że jest ona spowodowana wariantem genu, który jest przekazywany przez pokolenia. Jest to znane jako dziedziczna lub rodzinna chnr.3839
Badania genetyczne mogą identyfikować mutacje związane z rodzinną chnr, ale są one przede wszystkim stosowane u osób z silną rodzinną historią choroby.40 Ze względu na dużą liczbę potencjalnych genów przyczynowych, diagnostyka genomowa chnr wymaga testów opartych na badaniu genomu lub eksomów (a nie testowania pojedynczych genów, jak w przypadku choroby Huntingtona).41
Złożoność genetyczna chnr sprawia, że badania predykcyjne są znacznie bardziej skomplikowane niż w przypadku innych chorób. Dla większości genów związanych z chnr nie istnieją specyficzne terapie modyfikujące przebieg choroby.42
Rola specjalistów w diagnostyce chnr
Skierowanie do neurologa
Jeśli lekarz pierwszego kontaktu podejrzewa chnr, pacjent powinien zostać skierowany do neurologa w celu szczegółowej oceny.43 Wczesna i specjalistyczna diagnoza jest niezbędna, dlatego pacjenci, u których podejrzewa się chnr, powinni być kierowani z wysokim priorytetem do doświadczonego neurologa.44 W przypadku podejrzenia chnr zaleca się skierowanie pacjenta do neurologa mającego doświadczenie w diagnostyce tej choroby. Skierowanie do neurologa w jednej ze specjalistycznych klinik chnr jest również wskazane w celu potwierdzenia diagnozy.4546
Towarzystwo MND współpracuje z Royal College of General Practitioners (RCGP) w celu wsparcia wczesnej diagnostyki chnr. Ich narzędzie „Red Flag” ma na celu pomoc lekarzom pierwszego kontaktu w dokonywaniu dokładnych skierowań, a tym samym skrócenie czasu do diagnozy.47
Multidyscyplinarne podejście do diagnostyki
Ze względu na złożoność chnr i jej wpływ na różne aspekty życia pacjenta, multidyscyplinarne podejście do diagnostyki i leczenia jest niezwykle ważne.48 Polikliniki chnr angażują skoordynowany zespół, który może obejmować doświadczony personel pielęgniarski, lekarzy rehabilitacyjnych, lekarzy opieki paliatywnej, neurologów, gastroenterologów, pulmonologów, logopedów, fizjoterapeutów, terapeutów zajęciowych, pracowników socjalnych, psychiatrów, psychologów i dietetyków.49
Badania wykazały, że pacjenci z chnr żyją dłużej i lepiej pod opieką zespołu multidyscyplinarnego.50 W porównaniu z tradycyjnymi modelami standardowej opieki ambulatoryjnej, kliniki multidyscyplinarne poprawiają przeżywalność pacjentów z ALS (najczęstszą formą chnr).51
Trudności diagnostyczne i błędne diagnozy
Choroby naśladujące chnr
Istnieje wiele chorób, które mogą naśladować chnr i mogą być leczone, dlatego ważne jest ich rozważenie w diagnostyce różnicowej.52 Początkowe objawy chnr mogą być podobne do objawów wielu innych schorzeń, dlatego pacjenci często przechodzą przez miesiące wizyt u różnych specjalistów, zanim zostanie postawiona diagnoza.53
Niektóre stany, które mogą przypominać chnr, obejmują:5455
- Stwardnienie rozsiane
- Rdzeniowy zanik mięśni
- Miastenia gravis
- Urazy rdzenia kręgowego
- Neuropatie obwodowe
- Guzy mózgu i rdzenia kręgowego
- Udar mózgu
- Choroba Parkinsona
- Choroba Alzheimera
Podtypy chnr i ich diagnoza
Choroba neuronu ruchowego obejmuje grupę schorzeń, które różnią się w zależności od lokalizacji i typu uszkodzonych neuronów ruchowych. Najczęstszym podtypem jest stwardnienie zanikowe boczne (ALS), które stanowi około 90% przypadków.56
Niektórzy pacjenci z chnr dowiadują się, że mają mniej powszechną formę choroby, taką jak pierwotne stwardnienie boczne (PLS) lub zanik mięśni postępujący (PMA). PLS wpływa tylko na górne neurony ruchowe, a PMA tylko na dolne neurony ruchowe. Pierwsze objawy tych form są bardzo podobne do innych, częstszych form schorzenia, więc we wczesnych stadiach trudno je odróżnić.5758
Choroby neuronu ruchowego mogą być również klasyfikowane na podstawie miejsca, w którym zaczynają się objawy. Na przykład, jeśli występują one w obszarze mowy i połykania (nerwy ruchowe wywodzące się z „opuszki” pnia mózgu), to określa się to jako chnr z początkiem opuszkowym.59
Komunikowanie diagnozy i wsparcie psychologiczne
Komunikowanie diagnozy chnr jest trudnym zadaniem dla lekarzy. Prawie 70% neurologów zgłasza, że przekazanie diagnozy chnr jest dla nich trudne, a 65% odczuwa umiarkowany do wysokiego stres i niepokój przy przekazywaniu diagnozy.60
Diagnoza powinna być przekazana przez konsultanta z dobrą znajomością pacjenta. Powinna być przekazana osobiście, zapewniając wystarczająco dużo czasu na dyskusję.61 Po diagnozie pacjent powinien otrzymać dane kontaktowe specjalisty opieki nad chorymi z chnr. Są to pracownicy służby zdrowia z doświadczeniem w opiece nad osobami z chnr, którzy będą mogli zapewnić dodatkowe wsparcie po diagnozie i podczas trwania choroby.62
Podkreśla się potrzebę lepszego wsparcia po przeprowadzeniu badań, z sugestiami obejmującymi obowiązkowe dostosowane sesje doradcze, możliwości wsparcia rówieśniczego, ciągłe monitorowanie oraz arkusz informacyjny z kolejnymi krokami, w tym informacjami o tym, jak uczestniczyć w badaniach.63
Badania wykazały, że terapia akceptacji i zaangażowania (ACT) może być skuteczna w utrzymaniu lub poprawie jakości życia pacjentów z chnr w porównaniu do standardowej opieki.64 Wsparcie psychologiczne, takie jak ACT, powinno być oferowane w ramach standardowego pakietu opieki wszystkim, którzy mogą z niego skorzystać.65
Nowe kierunki w diagnostyce chnr
Biomarkery i wczesne wykrywanie
Jednym z głównych wyzwań w badaniach nad chnr jest brak wiarygodnych biomarkerów do wczesnej diagnozy i monitorowania choroby.66 Naukowcy intensywnie pracują nad rozwojem nowych narzędzi diagnostycznych, które mogą wykryć wczesne oznaki chnr przed pojawieniem się objawów.67
Badacze z Uniwersytetu Aberdeen we współpracy z Uniwersytetem Edynburskim zidentyfikowali nowy sposób wykrywania oznak chnr w tkance mózgowej, który może wykryć wskaźniki chnr wcześniej i z większą czułością niż obecnie stosowane testy.68 Narzędzie to wykorzystuje aptamer TDP-43 do wykrywania uszkodzonych białek komórkowych w próbkach tkanki mózgowej, które mogą wskazywać na chnr przed dysfunkcją komórek – gdy zaczną pojawiać się objawy i na etapie, na którym obecne narzędzia mogą wykryć oznaki choroby.69
Naukowcy z Uniwersytetu Sussex zidentyfikowali potencjalny wzorzec we krwi, który sygnalizuje obecność chnr – odkrycie, które może znacznie poprawić diagnostykę.70 Znaleźli oni biomarker dla chnr składający się z kombinacji siedmiu ncRNA. Mają nadzieję, że po dalszych pracach nad walidacją tych biomarkerów, można będzie opracować test krwi, który pomoże poprawić diagnostykę chnr.71
Znaczenie wczesnej diagnozy
Wczesna diagnoza chnr ma kluczowe znaczenie dla skutecznego leczenia i poprawy jakości życia pacjentów.72 Lepsza zdolność do wykrywania choroby może umożliwić diagnozowanie osób z chnr wcześniej, gdy leki terapeutyczne mogą być znacznie bardziej skuteczne.73
Wczesne wykrywanie chnr u ludzi jest niezbędne, ponieważ zbliżamy się do czasu, gdy leczenie modyfikujące progresję choroby może stać się dostępne.74 Zmiany techniczne, takie jak odejście od przeciwciał w kierunku mniejszych syntetycznych cząsteczek RNA, jak w przypadku aptameru, mogą przyspieszyć postęp poprzez otwieranie nowych linii badań, prowadzących do nowych odkryć.75
Potrzebne są również solidne biomarkery choroby, aby wspierać ocenę tych metod leczenia i przyspieszać diagnozę, tak aby leczenie mogło być rozpoczęte wcześniej w przebiegu choroby.76
Leczenie po diagnozie chnr
Chociaż chnr pozostaje nieuleczalną chorobą, istnieją interwencje, które mogą wydłużyć życie i poprawić jego jakość.77
Riluzol jest jedynym lekiem, który wykazał korzystny wpływ na przeżycie w podwójnie ślepym, randomizowanym badaniu kontrolowanym placebo u pacjentów z najczęstszą postacią chnr – stwardnieniem zanikowym bocznym (ALS).78 Jest to jedyny lek zatwierdzony przez agencje regulacyjne, takie jak FDA i EMA, do leczenia ALS.79 Riluzol, lek przeciwglutaminianowy, jest terapią modyfikującą przebieg choroby, neuroprotekcyjną, która przedłuża przeżycie w ALS o około trzy miesiące.80 Jest dostępny w ramach Pharmaceutical Benefits Scheme i wykazano w badaniach klinicznych, że przedłuża przeżycie o kilka miesięcy i może pomóc pacjentom pozostać w łagodniejszej fazie choroby przez dłuższy czas.81
Edaravon jest innym lekiem, który został zatwierdzony do leczenia ALS w kilku krajach.82
Nieinwazyjna wentylacja wykazała przedłużenie życia i poprawę jego jakości.83
Interwencje, takie jak pomoc w przyjmowaniu pokarmów i oddychaniu, poprawiają jakość życia.84 Badania wykazały, że ludzie żyją lepiej i dłużej pod opieką zespołu multidyscyplinarnego.85
Rola opieki paliatywnej polega na oferowaniu holistycznego podejścia do opieki nad pacjentem poprzez zapewnienie odpowiedniego łagodzenia objawów, wytchnienia i planowania opieki u schyłku życia oraz zaspokajanie potrzeb psychospołecznych.86 Wczesne skierowanie do specjalistycznej opieki paliatywnej powinno być dostępne, gdy tylko pacjent uzna to za stosowne i jest w stanie zaakceptować skierowanie.87
Opieka paliatywna może pomóc, jeśli pacjent ma złożone objawy, potrzebuje adaptacji domu lub sprzętu, doświadcza zmiany w zdolnościach fizycznych lub poznawczych, lub przechodzi emocjonalny lub duchowy dystres.88
Podsumowanie procesu diagnostycznego chnr
Diagnostyka choroby neuronu ruchowego jest złożonym procesem wymagającym doświadczenia klinicznego, odpowiednich badań i czasu. Polega głównie na wykluczeniu innych schorzeń, które mogą powodować podobne objawy, oraz obserwacji progresji objawów klinicznych.89 Chociaż nie istnieje pojedynczy test diagnostyczny dla chnr, kombinacja badania klinicznego, testów elektrofizjologicznych, badań obrazowych i laboratoryjnych może wspomóc proces diagnostyczny.90
Szybka i dokładna diagnoza ma kluczowe znaczenie dla zapewnienia, że potrzeby osób żyjących z chnr są zaspokajane od jak najwcześniejszego etapu.91 Wcześniejsza diagnoza pozwala pacjentom maksymalizować jakość pozostałego życia i poprawia planowanie opieki.92
Diagnostyka powinna być prowadzona przez doświadczonego neurologa, z wykorzystaniem multidyscyplinarnego podejścia do opieki, które wykazało korzyści w zakresie przeżywalności i jakości życia pacjentów z chnr.93 Choć chnr pozostaje devastującą chorobą bez możliwości wyleczenia, postępy w badaniach nad nowymi biomarkerami i metodami wczesnej diagnostyki dają nadzieję na poprawę opieki i potencjalnie skuteczniejsze leczenie w przyszłości.9495

- #1 Diagnosis and management of motor neurone diseasehttps://pmc.ncbi.nlm.nih.gov/articles/PMC2270983/
Motor neurone disease is a devastating illness which leads to progressive paralysis and eventual death. […] Motor neurone disease is rare but patients often are aware of it, so this review should help non-specialists reassure patients in whom it is unlikely to be the diagnosis. […] A diagnosis of motor neurone disease relies on interpretation of the clinical symptoms and signs and use of investigations to exclude other causes. […] The lack of a definitive test can cause problems, particularly if patients are seen very early after onset of symptoms, when the signs may be limited. […] Several conditions can mimic motor neurone disease and may be treatable, and it is important to consider these. […] Riluzole is the only drug identified to have a beneficial effect on survival, following a double blind, randomised placebo controlled trial in patients with the common amyotrophic lateral sclerosis variant of motor neurone disease.

The most important component in the diagnosis of MND is taking a history from a patient and conducting a thorough neurological examination. There is no single test to diagnose motor neurone disease and every patient is different. The medical team decides which tests should be performed on a case by case basis. Tests are performed to look for supportive features of motor neurone disease and to look for other possible causes of a patientâs symptoms. […] Tests that may be requested by the medical team to help diagnose MND include: […] There is no blood test to diagnose MND. However, blood tests might be performed to look for evidence of damage to the muscle (called CK, or creatine kinase), to look for causes of inflammation in the spinal cord (such as vitamin B12 levels) or to look for supportive evidence of damage to the motor nerves (such as anti-ganglioside antibodies). The appropriateness of each test is determined on a patient by patient basis and, as all patients are different, not all the tests may be performed on every patient.

The diagnosis of motor neurone disease (MND) is often clinically difficult, and sometimes it is necessary to review a person and observe symptom progression for some time before the diagnosis becomes reasonably certain. […] Rapid and accurate diagnosis is crucial in ensuring the needs of people living with MND are met from the earliest possible stage. […] If MND is suspected is it important to refer the person to a neurologist expert in diagnosing motor neurone disease. A referral to a neurologist at one of the specialist MND Clinics is also advisable to confirm a diagnosis of MND. […] Patients with symptoms suggestive of ALS should be assessed as soon as possible by an experienced neurologist. Early diagnosis should be pursued, and investigations, including neurophysiology, performed with high priority.

Motor neurone disease (MND) is still incurable, but not untreatable many symptoms can be managed. […] MND is still incurable, but it is not untreatable, as many symptoms can be managed. The drug riluzole available on the Pharmaceutical Benefits Scheme has been demonstrated in clinical trials to prolong survival by several months and may help people to remain in the milder phase of the disease for longer. […] Research has shown that people live better and longer under the care of a multidisciplinary team. Interventions such as assistance with nutritional intake and breathing improve quality of life.
- #5 HealthtalkPath to diagnosis of MND | Real People. Real life experiences. | Healthtalkhttps://healthtalk.org/experiences/motor-neurone-disease-mnd/path-diagnosis-mnd/
Diagnosing motor neurone disease is often a difficult and lengthy process. This is for several reasons. Firstly, MND is comparatively rare. Secondly, it affects each person in a different way; there is no definitive symptom which would immediately suggest the diagnosis. In addition, the early symptoms can be quite mild and could be caused by various other conditions. These need to be ruled out before a diagnosis of MND is given, and no simple test exists to diagnose MND. Several people talked about their tests as a âprocess of eliminationâ. Progression of symptoms over time provides evidence to support the diagnosis. […] Many of the people we talked to had been experiencing symptoms for months or even years before finally getting a diagnosis. […] Most people, once they went to their GP, felt they had been referred promptly to a specialist in neurological conditions.

Weak and wasted muscles with retained reflexes is highly suggestive of MND until proven otherwise. Consider the diagnosis when faced with progressive painless weakness in patients over the age of 50. […] The diagnosis of MND is clinical, although usually supported by investigations such as electromyography and nerve conduction studies (EMG/NCS), imaging and blood work. […] Diagnostic criteria for MND exist, but these are not useful in routine clinical practice. […] The misdiagnosis of MND (particularly of the ALS phenotype), is uncommon. Atypical presentations, particularly of focal onset and with pure LMN or UMN signs, present a more difficult diagnostic challenge, although perhaps reassuringly, treatable mimics are rare. A working knowledge of potential alternative conditions and MND diagnostic pitfalls should help to reduce the misdiagnosis rate, particularly if the key points are considered.

There is no diagnostic test for MND, and the quest for biomarkers is ongoing. […] The most robust marker of prognosis is still the interval from symptom onset to definitive diagnosis, the average for which has remained approximately 1 year, around a third of the median survival from symptom onset. […] The physical signature of classical MND is captured once again, but importantly only in the context of a prior history of progressive weakness. […] There are a handful of key signs on examination that, in the presence of a history of progressive weakness in someone aged over 50 years, should immediately prompt consideration of the diagnosis of MND. […] The common perception that MND patients are premorbidly fitter or more athletic remains attractive but unproven. […] The very rare (2%) patients with a pure UMN syndrome, termed primary lateral sclerosis, are characterised by slow progression, but may be difficult to distinguish from the so-called UMN-predominant forms of ALS.
- #9 Motor Neurone Disease (MND) – Queensland Brain Institute – University of Queenslandhttps://qbi.uq.edu.au/the-brain/motor-neurone-disease
Motor neurone disease (MND) is a rapidly progressing neurological disorder that attacks the nerve cells in the brain and spinal cord controlling the way we walk, talk, eat, speak, and breathe. […] The path to diagnosis can be a long one, and the average time from the onset of symptoms to diagnosis can range anywhere between 10 to 18 months. […] For most patients, the average life expectancy after diagnosis is 27 months. […] Although there is currently no cure for MND, the drug riluzole (sold as Rilutek or APO-Riluzole) is approved in Australia for people with MND. Riluzole cannot cure MND, but for some patients, it can slow the progression of the disease and prolong survival by two to three months.
- #10 Mimics and chameleons in motor neurone disease | Practical Neurologyhttps://pn.bmj.com/content/13/3/153
The progression of motor neurone disease (MND) is currently irreversible, and the grave implications of diagnosis naturally fuels concern among neurologists over missing a potential mimic disorder. There is no diagnostic test for MND but in reality there are few plausible mimics in routine clinical practice. […] Lack of confidence about the scope of such variation, or an approach to diagnosis emphasising investigations over clinical common sense, has the potential to exacerbate diagnostic delay in MND and impede timely planning of the care which is essential to maximising quality of life. […] The diagnosis of MND is only very rarely reversed in favour of a treatable disorder and, in our experience, the reaction of the patient in this situation is one of relief not hostility. Conversely, significant distress can arise from avoidable diagnostic delay and this may permanently erode confidence in onward management.
- #11 Motor neurone disease (MND) | NHS informhttps://www.nhsinform.scot/illnesses-and-conditions/brain-nerves-and-spinal-cord/motor-neurone-disease-mnd/
Diagnosing motor neurone disease (MND) can be difficult during the early stages. This is because many of the first symptoms can be caused by other more common health conditions like: […] MND is usually diagnosed by a neurologist based on the symptoms and a physical examination. […] There are many reasons why there may be delays in diagnosis. The initial symptoms might not appear to be serious. Or symptoms might not be recognised as being related to the nervous system so a neurologist isnt consulted at first. […] Sometimes, the diagnosis of MND is clear without the need for further tests. Confirming a diagnosis can sometimes be time-consuming even for an experienced neurologist. They might need a period of observation to be sure, particularly in cases where the condition progresses slowly. MND can only be diagnosed if the symptoms are clearly getting worse (progressive).

- #13 Motor Neurone Disease (MND): Causes and Treatment | Doctorhttps://patient.info/doctor/motor-neurone-disease-pro
Motor neurone disease (MND) is a rare but devastating neurodegenerative condition that affects the brain and spinal cord, leading to progressive paralysis and eventual death. […] Diagnosis should be made after consideration of the clinical signs and symptoms together with investigations to exclude other causes. […] Because of the very variable clinical presentation, the diagnostic criteria below have been devised, taking into account investigations to confirm the diagnosis and refute other possible causes (revised El Escorial Criteria): […] The World Federation of Neurology (WFN) has proposed further revision in the light of advances in neurophysiological techniques which can accurately detect degenerative neurological changes. They recommend upgrading the neurophysiological findings and making them as significant as the clinical findings in the diagnosis of ALS.
- #14 Mimics and chameleons in motor neurone disease | Practical Neurologyhttps://pn.bmj.com/content/13/3/153
The diagnosis of MND is a clinical diagnosis and there are no mandatory investigations. […] An earlier diagnosis allows patients to maximise the quality of their remaining life and improves care-planning. […] A progressive motor syndrome with mixed upper and lower motor neurone signs in more than one body region has few, if any, differential diagnoses. […] Lower motor neurone-predominant monomelic clinical sub-types of MND present the greatest diagnostic challenge but are frequently more slowly progressive. […] Bulbar-onset MND is not uniformly associated with a rapid progression, and symptoms may remain isolated to this territory with apparently normal EMG studies. […] MND overlaps pathologically with frontotemporal dementia and around 10% of MND patients develop pronounced cognitive impairment (typically as an early feature).
- #15 Motor Neuron Disease (MND) – almostadoctorhttps://almostadoctor.co.uk/encyclopedia/motor-neuron-disease-mnd
Motor neuron disease (aka MND, Motor neurone disease, amyotrophic lateral sclerosis ALS) is degenerative neurological disease, seen worldwide. In MND is degeneration of motor neurons in the motor cortex and spinal cord, affecting both upper and lower motor neurons. […] MND is a general term used to describe several types of motor neurone degeneration. […] Usually diagnosis is clinical, but may be confirmed by EMG and nerve conduction studies. There needs to be: UMN and LMN signs, No sensory signs, Progressive pattern. […] EMG shows denervation and fibrillation. […] Nerve conduction studies will appear normal. Useful to exclude multifocal neuropathy. […] The disease is progressive, and survival is usually less than 3 years. […] No treatments have been proven to improve outcome.

Weak and wasted muscles with retained reflexes is highly suggestive of MND until proven otherwise. Consider the diagnosis when faced with progressive painless weakness in patients over the age of 50. […] The diagnosis of MND is clinical, although usually supported by investigations such as electromyography and nerve conduction studies (EMG/NCS), imaging and blood work. […] Diagnostic criteria for MND exist, but these are not useful in routine clinical practice. […] The misdiagnosis of MND (particularly of the ALS phenotype), is uncommon. Atypical presentations, particularly of focal onset and with pure LMN or UMN signs, present a more difficult diagnostic challenge, although perhaps reassuringly, treatable mimics are rare. A working knowledge of potential alternative conditions and MND diagnostic pitfalls should help to reduce the misdiagnosis rate, particularly if the key points are considered.

It is very likely that the medical team will request this test for all patients being investigated for motor neurone disease. A specialist doctor called a neurophysiologist performs the nerve conduction and EMG tests. They will decide which nerves and muscles to test on a case by case basis and then analyse the results to establish whether or not the findings support a diagnosis of MND or are suggestive of another condition. […] Sometimes a patient may have to undergo nerve conduction studies and EMG on more than one occasion so that any changes over time can be identified. […] The medical team may decide to perform an MRI scan based upon a patientâs history and examination. MRI scans are performed in the radiology department and the images are reviewed by a specialist doctor called a radiologist who reports the scan. The MRI scan cannot diagnose motor neurone disease but can look for evidence of other causes of a patientâs symptoms such as damage to the spinal cord in the neck (upper motor neurone) and the nerves that leave the neck to supply the muscles (lower motor neurone) caused by âwear and tearâ changes.

All types of MND can be differentiated by two defining characteristics: Is the disease sporadic or inherited? Is there involvement of the upper motor neurons (UMN), the lower motor neurons (LMN), or both? […] The EMG, which evaluates muscle function, and NCS, which evaluates nerve function, are performed together in patients with LMN signs. […] For patients with MND affecting the LMNs, the EMG will show evidence of: (1) acute denervation, which is ongoing as motor neurons degenerate, and (2) chronic denervation and reinnervation of the muscle, as the remaining motor neurons attempt to fill in for lost motor neurons.

Diagnosing motor neurone disease can be difficult, and so sometimes a diagnosis may take time as the neurologist would like to observe a person over a period of time to see how the symptoms may change or respond to tests. […] Several other neurological conditions resemble motor neurone disease, especially in the early stages, and so these need to be checked for and ruled out as part of the diagnostic process. […] The diagnosis can be assisted through a range of tests, including some which eliminate other conditions.

There is no single test to work out if you have MND. Getting MND diagnosed involves assessment by a neurologist and tests to rule out other causes. […] It took several tests and visits to different places before MND was diagnosed. […] If your neurologist thinks a neurological problem is causing your symptoms, they may do tests. There is no single test to get MND diagnosed, but a range of tests can help rule out other causes. […] TMS measures the activity of the upper motor neurones to help diagnosis. […] An MRI scan involves being placed in a cylinder-like machine. The machine takes internal images of the body and your neurologist uses these to help rule out conditions such as stroke, Alzheimers disease, Parkinsons disease, multiple sclerosis, tumours and trapped nerves. These scans can also detect injury to the spine and brain.
- #55 Pathology of Motor Neuron Disorders: Definition, Etiology, Epidemiologyhttps://emedicine.medscape.com/article/2111360-overview
Motor neuron disorders (MNDs) are a clinically and pathologically heterogeneous group of neurologic diseases characterized by progressive degeneration of motor neurons; they include both sporadic and hereditary diseases. […] MNDs can be classified into those affecting primarily the UMNs, those affecting primarily the LMNs, and those affecting both, and the nomenclature is used accordingly. The patients symptoms vary, depending on which set of motor neurons is involved. […] ALS, also known as Lou Gehrig disease, is the most common neurodegenerative disease of adult onset involving the motor neuron system. It is a fatal disorder and is characterized by progressive skeletal muscle weakness and wasting or atrophy (ie, amyotrophy), spasticity, and fasciculations as a result of degeneration of the UMNs and LMNs, culminating in respiratory paralysis.
- #56 Motor neuron disease/ALS | UK DRIhttps://www.ukdri.ac.uk/conditions/motor-neuron-diseaseals
Motor neuron disease (MND) is the general name thatâs given to a group of illnesses which can affect nerves called motor neurons in the brain and spinal cord. […] The most common subtype of MND is amyotrophic lateral sclerosis (ALS), which contributes approximately 90% of cases. […] If you or someone you care about is experiencing symptoms of motor neuron disease/ALS, please contact a GP for an accurate diagnosis and to rule out other conditions. […] There is no single diagnostic test for MND/ALS; instead, diagnosis is based on a combination of clinical history and a medical examination. Various tests such as electromyography or nerve conduction may also be carried out. […] Electromyography (EMG) is a type of diagnostic test thatâs used to assess the health of muscles and the nerve cells (or motor neurons) that control them.

In about 5-10% of people, there is a family history of the condition, indicating that the disease is caused by a variant of a gene which is passed through the generations. This is known as inherited or familial MND. […] A few people diagnosed with MND will be told they have a less common form of the condition such as PLS (primary lateral sclerosis) or PMA (progressive muscular atrophy). PLS affects only the upper motor neurones, and PMA only the lower motor neurones. The first symptoms of these forms are very similar to other more common forms of the condition, so in the early stages it can be difficult to distinguish them.

- #59 What’s the difference between MND and ALS? – Oxford University Hospitalshttps://www.ouh.nhs.uk/services/departments/neurosciences/neurology/mnd/support/mnd-als.aspx
The term Motor Neuron Disease (MND) encompasses several different conditions whose common feature is the premature degeneration of motor nerves (known as neurons or sometimes neurones). […] MND was first described in the mid-late 1800s, and the French Neurologist Jean-Martin Charcot is widely credited with the first detailed descriptions. […] Charcot’s genius was to recognise that in MND both processes were occurring simultaneously. He called it Amyotrophic Lateral Sclerosis (ALS). […] Nearly 90 percent of patients with MND have the mixed ALS form of the disease, so that the terms MND and ALS are commonly used to mean the same thing. […] There are other ways that neurologists sometimes categorise MND cases. One method is by the site where the disease symptoms being – for example if it is in the speech and swallowing motor nerves (which arise from the 'bulb’ of the brain stem) then it is termed bulbar-onset MND.

Given the genomic heterogeneity of MND, testing an unaffected relative for variants in a panel of MND-linked genes might prove inaccurate if the causal gene in the affected relative was not included. […] Pathogenic and likely pathogenic variants in MND-linked genes are overrepresented in population cohorts and databases such as gnomAD. […] Reduced penetrance can introduce complications for family members considering predictive testing, and should be carefully explained during genetic counselling to help them weigh up the utility of predictive testing and consider their own tolerance for uncertainty. […] For most MND-linked genes, there are no specific disease modifying therapies. […] The motor phenotype of MND can vary, even within a family. […] There is extensive evidence on the psychosocial impact of predictive genetic testing for HD. In contrast, the research evidence in MND is limited – making it difficult to appreciate the risk: benefit ratio for predictive testing in these families. […] The need for improved post-test support has been emphasised, with suggestions including mandatory tailored counselling sessions, peer support opportunities, ongoing monitoring, and an information sheet with next steps, including how to participate in research.

MND is a progressive, neurodegenerative disease with no cure. It affects motor neurons, which are found in the brain and spinal cord, that help tell your muscles what to do. MND causes these messages to stop reaching the muscles, causing them to weaken, stiffen and gradually die. […] This study provides strong evidence that Acceptance and Commitment Therapy can be a valuable tool for improving quality of life for the 5,000 people who are currently living with MND in the UK. […] The results were positive, with ACT plus usual care shown to be effective at maintaining or improving quality of life in patients with MND at six and nine months post-randomisation compared to usual care alone.

Diagnosing motor neurone disease is often a difficult and lengthy process. This is for several reasons. Firstly, MND is comparatively rare. Secondly, it affects each person in a different way; there is no definitive symptom which would immediately suggest the diagnosis. In addition, the early symptoms can be quite mild and could be caused by various other conditions. These need to be ruled out before a diagnosis of MND is given, and no simple test exists to diagnose MND. Several people talked about their tests as a 'process of elimination’. Progression of symptoms over time provides evidence to support the diagnosis. Many of the people we talked to had been experiencing symptoms for months or even years before finally getting a diagnosis. Some lived with their symptoms for a long time before deciding to go to their GP, perhaps putting them down to stress, old age, or injury.
- #90 ALS – Wikipediahttps://en.wikipedia.org/wiki/ALS
Amyotrophic lateral sclerosis (ALS), also known as motor neuron disease (MND), is a rare, terminal neurodegenerative disorder that results in the progressive loss of both upper and lower motor neurons that normally control voluntary muscle contraction. The diagnosis is based on a person’s signs and symptoms, with testing conducted to rule out other potential causes. No single test can provide a definite diagnosis of ALS. Instead, the diagnosis of ALS is primarily made based on a physician’s clinical assessment after ruling out other diseases. Physicians often obtain the person’s full medical history and conduct neurologic examinations at regular intervals to assess whether signs and symptoms such as muscle weakness, muscle atrophy, hyperreflexia, Babinski’s sign, and spasticity are worsening. Many biomarkers are being studied for the condition, but as of 2023 are not in general medical use.

The diagnosis of motor neurone disease (MND) is often clinically difficult, and sometimes it is necessary to review a person and observe symptom progression for some time before the diagnosis becomes reasonably certain. […] Rapid and accurate diagnosis is crucial in ensuring the needs of people living with MND are met from the earliest possible stage. […] If MND is suspected is it important to refer the person to a neurologist expert in diagnosing motor neurone disease. A referral to a neurologist at one of the specialist MND Clinics is also advisable to confirm a diagnosis of MND. […] Patients with symptoms suggestive of ALS should be assessed as soon as possible by an experienced neurologist. Early diagnosis should be pursued, and investigations, including neurophysiology, performed with high priority.

The diagnosis of MND is a clinical diagnosis and there are no mandatory investigations. […] An earlier diagnosis allows patients to maximise the quality of their remaining life and improves care-planning. […] A progressive motor syndrome with mixed upper and lower motor neurone signs in more than one body region has few, if any, differential diagnoses. […] Lower motor neurone-predominant monomelic clinical sub-types of MND present the greatest diagnostic challenge but are frequently more slowly progressive. […] Bulbar-onset MND is not uniformly associated with a rapid progression, and symptoms may remain isolated to this territory with apparently normal EMG studies. […] MND overlaps pathologically with frontotemporal dementia and around 10% of MND patients develop pronounced cognitive impairment (typically as an early feature).
- #93 Multidisciplinary management of motor neurone diseasehttps://www1.racgp.org.au/ajgp/2018/september/multidisciplinary-management-of-motor-neurone-dise
Given its progressive and debilitating nature and the lack of cure, management of MND is focused on symptomatic relief, optimising quality of life and timely palliative care involvement. Early referral to a dedicated MND multidisciplinary clinic is important to address the multiple facets and highly specific and complex individual care needs of this group. […] Riluzole, an anti-glutamatergic agent, is a disease-modifying, neuroprotective therapy that prolongs survival in ALS by approximately three months. […] Multidisciplinary clinics, when compared with traditional models of standardised outpatient care, improve survival in ALS patients. […] Health-related instruments that measure quality of life, such as the Revised ALS Functional Rating Scale, are simple yet valuable tools used in these multidisciplinary clinics to assess function and predict survival in ALS patients.

Step changes in technical approaches such as moving away from antibodies towards smaller synthetic RNA molecules, as with this aptamer can accelerate progress by unlocking new lines of research, leading to new insights. […] Whilst this current development is not an early diagnostic test, it could help researchers reach that goal. […] However, we now need robust biomarkers of disease to support the evaluation of these treatments and to speed up diagnosis, so that treatments can be started earlier in disease progression.

Understanding the mechanisms of action of current treatments is crucial for developing more effective therapies. […] The future of MND research is focused on uncovering the underlying mechanisms of the disease and developing novel therapeutic approaches. […] One of the significant challenges in MND research is the lack of reliable biomarkers for early diagnosis and disease monitoring. […] The future of MND research holds promise, with emerging therapies such as gene editing, stem cell transplantation, and immunotherapy offering hope for more effective treatments. […] Ultimately, continued research and collaboration across disciplines will be essential to unlock new insights into MND and improve the lives of those affected by this relentless disease.
