Problemy z równowagą
Patofizjologia i mechanizm
Zaburzenia równowagi wynikają z dysfunkcji jednego lub więcej systemów sensorycznych odpowiedzialnych za utrzymanie stabilności ciała, w tym układu przedsionkowego, wzrokowego oraz somatosensorycznego. Patogeneza obejmuje m.in. uszkodzenia ucha wewnętrznego (np. BPPV spowodowane przemieszczeniem otokonii, choroba Ménière’a z wodniakiem śródchłonkowym, zapalenie nerwu przedsionkowego), centralne zaburzenia neurologiczne (migrena przedsionkowa, udar mózgu, stwardnienie rozsiane, choroba Parkinsona) oraz czynniki ogólnoustrojowe, takie jak zaburzenia krążenia, neuropatie, leki ototoksyczne czy procesy starzenia. Warto podkreślić, że u osób starszych obserwuje się spadek liczby komórek nerwowych w układzie przedsionkowym, pogorszenie propriocepcji i siły mięśniowej (spadek siły mięśniowej po 50-60 roku życia, nawet o 50% do 80 roku życia), co dodatkowo zwiększa ryzyko upadków i niestabilności. Kompensacja centralna odgrywa kluczową rolę w adaptacji po uszkodzeniu układu przedsionkowego, jednak jej skuteczność może być ograniczona przy współistnieniu uszkodzeń wielosystemowych.

Patogeneza problemów z równowagą
Problemy z równowagą (zaburzenia równowagi) to stan, który powoduje, że osoba czuje się niestabilna, zawrota lub ma wrażenie ruchu, wirowania bądź unoszenia się. Patogeneza tych zaburzeń jest złożona i obejmuje dysfunkcję jednego lub więcej systemów odpowiedzialnych za utrzymanie równowagi w organizmie.12
System równowagi w organizmie człowieka
Utrzymanie równowagi zależy od prawidłowego funkcjonowania i koordynacji między trzema głównymi systemami sensorycznymi: przedsionkowym, wzrokowym i somatosensorycznym. Każdy z tych systemów dostarcza mózgowi informacji o pozycji ciała i głowy w przestrzeni oraz o ich ruchu.12
System przedsionkowy (błędnikowy) znajduje się w uchu wewnętrznym i składa się z trzech kanałów półkolistych oraz dwóch narządów otolitowych (łagiewki i woreczka). Te struktury wykrywają ruchy i zmiany pozycji głowy, a następnie przekazują sygnały do mózgu za pośrednictwem nerwu przedsionkowego.12
Kanały półkoliste wykrywają ruch obrotowy głowy, podczas gdy narządy otolitowe reagują na grawitację i przyspieszenie liniowe. W narządach otolitowych znajdują się kryształy węglanu wapnia (otoconia), które są cięższe od otaczających je struktur. Gdy głowa zmienia pozycję, grawitacja powoduje przemieszczenie tych kryształów, co pociąga za sobą warstwę galaretowatą i komórki rzęsate, generując sygnał przesyłany do mózgu.12
System wzrokowy dostarcza informacji o położeniu ciała względem otoczenia, a system somatosensoryczny (proprioceptywny) przekazuje dane o pozycji stawów i napięciu mięśni.1
Mózg integruje wszystkie te informacje, tworząc spójny obraz pozycji i ruchu ciała, a następnie wysyła sygnały do mięśni w celu utrzymania równowagi.1
Mechanizmy patofizjologiczne zaburzeń równowagi
Zaburzenia równowagi powstają, gdy system równowagi nie funkcjonuje prawidłowo z powodu uszkodzenia lub dysfunkcji jednego lub więcej jego komponentów.1
Jednym z najczęstszych mechanizmów jest dysfunkcja układu przedsionkowego w uchu wewnętrznym. Może ona być spowodowana infekcjami, urazami, zaburzeniami krążenia lub innymi chorobami wpływającymi na struktury ucha wewnętrznego.12
Łagodne napadowe położeniowe zawroty głowy (BPPV) występują, gdy otoconia (kryształy węglanu wapnia) odrywają się od narządów otolitowych i przemieszczają do kanałów półkolistych. Tam poruszają się wraz z endolimfą przy zmianach pozycji głowy, powodując nieprawidłowe pobudzenie receptorów i wysyłanie błędnych informacji do mózgu o ruchu głowy, czego efektem są zawroty głowy.12
Choroba Ménière’a to stan charakteryzujący się nadmiernym gromadzeniem się endolimfy w uchu wewnętrznym (wodniak śródchłonkowy). Patogeneza rozpoczyna się od niewystarczającego wchłaniania endolimfy i jej akumulacji w schodach środkowych ucha wewnętrznego. Powoduje to ciężkie zawroty głowy, jednostronny ubytek słuchu, szumy uszne i uczucie pełności w uchu.12
Zapalenie nerwu przedsionkowego powstaje, gdy nerw przedsionkowy, który łączy ucho wewnętrzne z mózgiem, ulega zapaleniu, najczęściej w wyniku infekcji wirusowej. Powoduje to nagłe, silne zawroty głowy i zaburzenia równowagi, które mogą utrzymywać się przez kilka tygodni, aż do czasu wykształcenia się centralnej kompensacji.12
Zapalenie błędnika występuje, gdy infekcja rozprzestrzenia się na struktury labiryntu w układzie przedsionkowym, powodując zarówno zawroty głowy, jak i utratę słuchu.1
Inne przyczyny zaburzeń równowagi
Oprócz schorzeń ucha wewnętrznego, problemy z równowagą mogą być spowodowane przez różne czynniki, w tym:12
- Zaburzenia układu nerwowego, takie jak choroba Parkinsona, stwardnienie rozsiane, choroba Alzheimera, udar mózgu czy uszkodzenie móżdżku lub pnia mózgu
- Urazy głowy i urazy mózgu
- Zaburzenia krążenia, w tym niskie ciśnienie krwi, arytmie serca, choroba niedokrwienna serca
- Efekty uboczne leków, zwłaszcza przeciwdepresyjnych, przeciwdrgawkowych, przeciwhistaminowych i leków na ciśnienie krwi
- Neuropatie obwodowe
- Problemy ze wzrokiem
- Zaburzenia mięśniowo-szkieletowe, takie jak zapalenie stawów czy bóle stawów
- Stres i zaburzenia lękowe
- Naturalne procesy starzenia się
Procesy patofizjologiczne w centralnych zaburzeniach równowagi
Centralne zaburzenia równowagi wynikają z problemów w mózgu, szczególnie w pniu mózgu lub móżdżku. Główne mechanizmy patofizjologiczne obejmują:12
Migrena przedsionkowa – zawroty głowy związane z migreną mogą wynikać z nakładania się dróg nerwowych bólu i równowagi w pniu mózgu. Podczas ataku migreny dochodzi do aktywacji tych szlaków, co prowadzi do zawrotów głowy i zaburzeń równowagi.1
Udar lub niedokrwienie mózgu – gdy dochodzi do przerwania lub ograniczenia dopływu krwi do obszarów mózgu odpowiedzialnych za równowagę, jak móżdżek czy pień mózgu, skutkuje to zaburzeniami równowagi i zawrotami głowy.12
Stwardnienie rozsiane (SM) – uszkodzenie osłonek mielinowych nerwów w centralnym układzie nerwowym zaburza przekazywanie sygnałów, co może prowadzić do problemów z równowagą. Układ immunologiczny atakuje komórki osłonki mielinowej (która chroni włókna nerwowe), co prowadzi do problemów zmniejszających zdolność centralnego układu nerwowego do komunikacji z ciałem.1
Choroba Parkinsona – zmiany w produkcji dopaminy wpływają na kontrolę motoryczną, powodując spowolnienie ruchów, drżenie i sztywność, co przyczynia się do problemów z równowagą i zwiększa ryzyko upadków.12
Mechanizmy fizjologiczne zaburzające równowagę
Konflikty sensoryczne
Kiedy różne systemy sensoryczne wysyłają do mózgu sprzeczne informacje, może to prowadzić do zaburzeń równowagi. Na przykład, gdy siedzimy w stojącym pociągu i obserwujemy ruszający się sąsiedni pociąg, oczy przekazują informację o ruchu, podczas gdy system przedsionkowy i proprioceptywny sygnalizują, że ciało jest nieruchome. Mózg musi rozstrzygnąć te sprzeczne dane, aby określić rzeczywistą sytuację, co może czasowo zaburzyć poczucie równowagi.1
Starzenie się układu równowagi
Z wiekiem dochodzi do stopniowego pogorszenia funkcjonowania systemu równowagi:12
- Zmniejsza się liczba komórek nerwowych w układzie przedsionkowym
- System przedsionkowy staje się mniej wrażliwy i wolniej reaguje na ruchy
- Pogarsza się ostrość proprioceptywna
- Spada siła mięśniowa (po 50-60 roku życia następuje przyspieszony spadek, nawet o 50% do 80 roku życia)
- Pogarsza się centralne przetwarzanie informacji z systemów równowagi
Mechanizm kompensacji centralnej
Po uszkodzeniu układu przedsionkowego mózg jest w stanie dostosować się i kompensować deficyty poprzez proces zwany kompensacją centralną. Polega on na zwiększonym poleganiu na innych systemach sensorycznych (głównie wzroku i propriocepcji) w celu utrzymania równowagi.1
Ten proces adaptacyjny może trwać tygodnie lub miesiące i jest kluczowy dla poprawy funkcji równowagi po uszkodzeniu. Jeśli jednak wystąpi uszkodzenie kilku systemów równocześnie (np. przedsionkowego i móżdżku), kompensacja centralna może być utrudniona, co prowadzi do przewlekłych problemów z równowagą.1
Nadmierne obciążenie systemu równowagi
U osób z zaburzeniami równowagi, zwłaszcza tymi dotyczącymi układu przedsionkowego, system równowagi staje się znacznie bardziej zależny od informacji wzrokowych. W rezultacie system ten może być bardziej podatny na przeciążenie, gdy jest wystawiony na zbyt dużą ilość informacji wzrokowych, takich jak ruch, wzory czy migające światła. Ta nadmierna stymulacja może prowadzić do zawrotów głowy i niestabilności.1
Patofizjologia konkretnych zaburzeń równowagi
BPPV (łagodne napadowe położeniowe zawroty głowy)
Patofizjologia BPPV opiera się na przemieszczeniu otokonii (kryształów węglanu wapnia) z narządów otolitowych do jednego z kanałów półkolistych, najczęściej tylnego. Kiedy głowa zmienia pozycję, przemieszczone otoconia poruszają się w endolimfie kanału, powodując nieprawidłowe pobudzenie kupuły (struktura zawierająca komórki rzęsate) i wysyłanie błędnych sygnałów do mózgu o ruchu głowy.12
Ta nieprawidłowa informacja o pozycji głowy wysyłana do mózgu wywołuje charakterystyczne, krótkotrwałe epizody zawrotów głowy występujące przy zmianie pozycji głowy. BPPV może być wywołane przez uraz głowy, infekcję ucha wewnętrznego lub może pojawić się spontanicznie, szczególnie u osób starszych.1
Choroba Ménière’a
Patogeneza choroby Ménière’a wiąże się z nadmiernym gromadzeniem się endolimfy w uchu wewnętrznym, co prowadzi do wodniaka śródchłonkowego. Rozpoczyna się od niewystarczającego wchłaniania endolimfy i jej akumulacji w schodach środkowych ucha wewnętrznego.1
To prowadzi do charakterystycznej triady objawów: epizodów ciężkich zawrotów głowy trwających od 20 minut do 12 godzin, szumów usznych oraz fluktuacyjnego, jednostronnego ubytku słuchu, który z czasem staje się trwały. U niektórych pacjentów występują również ataki upadania (drop attacks). Z powtarzaniem się ataków, jednostronny ubytek słuchu, zwłaszcza w niskich częstotliwościach, staje się trwały.12
Zapalenie nerwu przedsionkowego i błędnika
Zapalenie nerwu przedsionkowego występuje, gdy nerw przedsionkowy łączący ucho wewnętrzne z mózgiem ulega zapaleniu, najczęściej w wyniku infekcji wirusowej. Powoduje to nagłe, silne zawroty głowy, niestabilność i nudności, ale bez utraty słuchu. Test pchnięcia głową jest dodatni, a występuje poziomy oczopląs bijący w stronę zdrowego ucha.12
Zapalenie błędnika (labiryntitis) występuje, gdy infekcja rozprzestrzenia się na struktury labiryntu w uchu wewnętrznym, powodując zarówno zawroty głowy, jak i nagłą utratę słuchu.1
Okres centralnej kompensacji po ostrym zapaleniu nerwu przedsionkowego może pozostawiać pacjenta niestabilnym przez miesiące.1
Zespół MdDS (Mal de Débarquement)
Zespół MdDS charakteryzuje się uczuciem ciągłego kołysania lub huśtania, typowo po rejsie morskim lub innej podróży morskiej. W przeciwieństwie do choroby morskiej, która ustępuje po zakończeniu podróży, objawy MdDS utrzymują się na lądzie i mogą trwać tygodniami, miesiącami, a nawet latami.1
Patofizjologia tego zaburzenia nie jest w pełni zrozumiana, ale uważa się, że jest związana z nieprawidłową adaptacją ośrodkowego układu nerwowego do rytmicznych ruchów doświadczanych podczas podróży.1
Przetoka przychłonki
Przetoka przychłonki to stan, w którym płyn z ucha wewnętrznego przecieka do ucha środkowego przez nieprawidłowe połączenie. Może być spowodowana urazem głowy, intensywnym wysiłkiem fizycznym, infekcjami ucha lub zmianami ciśnienia atmosferycznego.1
Wyciek płynu zaburza normalne funkcjonowanie układu przedsionkowego, powodując problemy z równowagą i zawroty głowy.1
Nerwiak nerwu słuchowego
Nerwiak nerwu słuchowego (schwannoma przedsionkowy) to niezłośliwy guz rozwijający się na nerwie przedsionkowym, który łączy ucho wewnętrzne z mózgiem. Objawy obejmują postępujący jednostronny ubytek słuchu, szumy uszne oraz zawroty głowy lub zaburzenia równowagi.12
Wraz ze wzrostem guza, uciska on na struktury mózgu, co może prowadzić do nasilenia objawów neurologicznych.1
Patofizjologia zaburzeń równowagi w chorobach neurologicznych
Choroba Parkinsona i zaburzenia równowagi
W chorobie Parkinsona zaburzenia równowagi wynikają głównie z dwóch mechanizmów:1
- Zamarznięcie chodu (FOG) – nagłe, krótkotrwałe epizody niemożności rozpoczęcia lub kontynuowania chodu, które mogą prowadzić do upadków, szczególnie do przodu. Aby rozpocząć chodzenie, pacjenci z FOG wymagają szerszych ruchów od tyłu do przodu niż osoby bez FOG, a ten szerszy ruch do przodu może skutkować upadkiem do przodu.1
- Zaburzenia równowagi – wynikające z dysfunkcji ośrodków kontroli postawy w mózgu. Funkcja równowagi jest kluczowa dla unikania upadków, a strategie zapobiegawcze koncentrujące się na niestabilności postawy, takie jak rehabilitacja równowagi, mogą zmniejszyć liczbę upadków u pacjentów z chorobą Parkinsona.1
Spowolnione ruchy, drżenie i sztywność utrudniają poruszanie się osobom żyjącym z chorobą Parkinsona i narażają je na ryzyko upadków.1
Stwardnienie rozsiane i zaburzenia równowagi
Stwardnienie rozsiane (SM) to choroba autoimmunologiczna wpływająca na centralny układ nerwowy (mózg i rdzeń kręgowy). Układ odpornościowy atakuje komórki osłonki mielinowej (która chroni włókna nerwowe), co prowadzi do problemów zmniejszających zdolność centralnego układu nerwowego do komunikacji z ciałem.1
Problemy z równowagą i chodzeniem mogą być bezpośrednim wynikiem uszkodzenia przez SM części układu nerwowego odpowiedzialnych za mobilność lub mogą być spowodowane pośrednio przez inne objawy SM, takie jak zmęczenie, osłabienie mięśni, spastyczność czy zaburzenia czucia.1
Uszkodzenie w określonej części mózgu odpowiedzialnej za równowagę (móżdżku) może prowadzić konkretnie do utraty równowagi, co następnie może prowadzić do niestabilności podczas chodzenia.1
Udar mózgu i zaburzenia równowagi
Udar mózgu często powoduje osłabienie jednej strony ciała, co może utrudniać utrzymanie równowagi. Ponadto, udar może uszkodzić części mózgu odpowiedzialne za koordynację i równowagę, takie jak móżdżek i pień mózgu.1
Drugim głównym czynnikiem wpływającym na równowagę po udarze jest utrata czucia w dotkniętej chorobą stronie, szczególnie w nogach. Po udarze poruszanie się i utrzymanie równowagi może wymagać większej koncentracji, co jest trudne.1
U niektórych osób może wystąpić zawroty głowy, jeśli udar wystąpi w móżdżku lub pniu mózgu, obszarach kontrolujących równowagę w mózgu.1
Niektóre osoby doświadczają ataksji, czyli trudności z kontrolowaniem płynnych ruchów, a inne cierpią na zespół pushera, gdzie mają wrażenie, że są wyprostowane, nawet gdy mocno przechylają się na słabszą stronę.12
Pourazowe zaburzenia równowagi
Urazy mózgu, w tym wstrząśnienia mózgu, mogą uszkodzić system przedsionkowy i mózgowe ośrodki kontroli równowagi, prowadząc do zaburzeń równowagi. Około połowa osób z urazem mózgu (TBI) doświadcza zawrotów głowy i utraty równowagi na pewnym etapie swojego powrotu do zdrowia.1
Uraz ucha wewnętrznego może uszkodzić narządy odpowiedzialne za równowagę. Jeśli TBI uszkodzi system przedsionkowy, mogą wystąpić problemy z równowagą, zawroty głowy lub nagłe uczucie wirowania.1
Urazowe uszkodzenie pnia mózgu i móżdżku (części mózgu kontrolujące ruch) może utrudniać chodzenie i utrzymywanie równowagi.1
Ze względu na traumatyczny charakter tych urazów, łatwo zrozumieć, dlaczego równowaga może być zaburzona później, oprócz innych deficytów motorycznych, sensorycznych i poznawczych. Problemy z równowagą mogą być spowodowane samym TBI lub nawet lekami przepisanymi w celu wspomagania powrotu do zdrowia.1
Patofizjologia zaburzeń równowagi związanych z innymi systemami
Zaburzenia równowagi związane z układem krążenia
Problemy z układem krążenia mogą wpływać na równowagę poprzez zaburzenie przepływu krwi do mózgu i ucha wewnętrznego:1
- Niskie ciśnienie krwi – zwłaszcza ortostatyczne (występujące przy nagłej zmianie pozycji), może powodować zawroty głowy i niestabilność przez zmniejszenie dopływu krwi do mózgu
- Arytmie serca – mogą prowadzić do nieregularnego dopływu krwi do mózgu, powodując zawroty głowy
- Miażdżyca tętnic (stwardnienie tętnic) – ogranicza przepływ krwi przez naczynia krwionośne
- Niewydolność serca – zmniejsza ogólny przepływ krwi w organizmie
- Choroby zastawek serca – mogą zaburzać przepływ krwi
Inne stany mogące wpływać na przepływ krwi to odwodnienie i anemia.1
Zaburzenia równowagi związane z cukrzycą i poziomem cukru we krwi
Cukrzyca może powodować zawroty głowy i problemy z równowagą poprzez wpływ na inne układy. Gdy cukrzyca jest słabo kontrolowana, bardziej prawdopodobne są problemy ze wzrokiem i neuropatie obwodowe. Cukrzyca może również przyczyniać się do niskiego ciśnienia krwi.1
Ponadto, wpływ cukrzycy na poziom cukru we krwi może również przyczyniać się do zawrotów głowy i problemów z równowagą. Wysoki lub niski poziom cukru we krwi może powodować niewyraźne widzenie, dezorientację, zawroty głowy, osłabienie i brak koordynacji motorycznej.1
Zaburzenia równowagi związane ze stresem i lękiem
Stres emocjonalny i lęk mogą powodować zmiany w organizmie, które wpływają na równowagę. Po pierwsze, stres zmienia sposób, w jaki mózg reaguje i przetwarza bodźce. Możliwe jest utracenie niektórych automatycznych odruchów równowagi w okresach zwiększonego stresu.1
Stres i lęk mogą również wywołać hiperwentylację, która zmniejsza ilość tlenu docierającego do mózgu. Prowadzi to do uczucia lekkości i zawrotów głowy.1
U osób z przetrwałymi zawrotami głowy typu położeniowo-percepcyjnego (PPPD), mózg przechodzi stresujące lub alarmujące wydarzenie, takie jak migrena, atak paniki, epizod depresyjny lub omdlenie. Hormony stresu aktywują reakcję walki lub ucieczki, co może zmienić sposób, w jaki mózg postrzega ruch i przestrzeń.1
Zaburzenia równowagi związane z lekami
Zarówno leki na receptę, jak i dostępne bez recepty mogą powodować zawroty głowy lub problemy z równowagą. Częste przykłady to:1
- Leki przeciwhistaminowe
- Środki nasenne
- Środki uspokajające
- Leki na ciśnienie krwi
- Leki przeciwdepresyjne
- Narkotyki
- Leki przeciwdrgawkowe
Łączenie tych leków z alkoholem może nasilić zawroty głowy i problemy z równowagą.1
Niektóre leki są znane z ototoksycznego działania, co oznacza, że mogą uszkadzać ucho wewnętrzne, w tym struktury odpowiedzialne za równowagę, prowadząc do dysfunkcji przedsionkowej.1
Patofizjologia zaburzeń równowagi związanych z wiekiem
Problemy z równowagą często zaczynają pojawiać się w późniejszych latach życia człowieka. Z wiekiem następuje pogorszenie funkcjonowania systemu równowagi prowadzące do problemów z równowagą.12
Główne zmiany związane z wiekiem, które wpływają na równowagę, to:1
- Zmniejszenie liczby komórek nerwowych w układzie przedsionkowym
- Pogorszenie ostrości widzenia i innych funkcji wzrokowych
- Zmniejszenie siły mięśniowej i elastyczności
- Pogorszenie propriocepcji (świadomości pozycji ciała w przestrzeni)
- Zmiany w układzie krążenia, w tym zmniejszona elastyczność naczyń krwionośnych
- Zmiany w strukturach ucha wewnętrznego
Ponadto, niepełnosprawność fizyczna, taka jak zapalenie stawów i ból stawów, również przyczyniają się do problemów z równowagą u osób starszych.1
Z ogólnym spadkiem równowagi, który towarzyszy procesowi starzenia się, istotne jest, aby zawroty głowy lub problemy z równowagą nie były przypisywane wyłącznie normalnym konsekwencjom starzenia się, dopóki nie zostanie przeprowadzona dokładna ocena.1
Implikacje kliniczne patofizjologii zaburzeń równowagi
Zrozumienie patofizjologii zaburzeń równowagi ma kluczowe znaczenie dla właściwego diagnozowania i leczenia tych stanów. Złożoność ludzkiego systemu równowagi stwarza wyzwania w diagnozowaniu i leczeniu podstawowej przyczyny zaburzeń równowagi.1
Kluczowa integracja informacji uzyskanych przez układy przedsionkowy, wzrokowy i proprioceptywny oznacza, że zaburzenia wpływające na pojedynczy układ mogą znacznie zakłócić normalne poczucie równowagi u człowieka.1
Dysfunkcja przedsionkowa jako przyczyna zaburzeń równowagi stanowi szczególnie złożone wyzwanie ze względu na interakcję układu przedsionkowego z funkcjonowaniem poznawczym oraz stopień wpływu, jaki ma on na kontrolę ruchów oczu i postawy.1
Badania finansowane przez NIDCD mają na celu opracowanie potrzebnych testów do odpowiedniego diagnozowania zaburzeń równowagi, co może prowadzić do bardziej skutecznych strategii leczenia w przyszłości.1
Zrozumienie patofizjologii zaburzeń równowagi jest również ważne dla rozwoju ukierunkowanych interwencji rehabilitacyjnych, takich jak ćwiczenia rehabilitacji przedsionkowej, które mogą pomóc pacjentom lepiej koordynować elementy ich układu przedsionkowego i poprawić ogólną funkcję równowagi.1

- #1 Balance disorder – Wikipediahttps://en.wikipedia.org/wiki/Balance_disorder
A balance disorder is a disturbance that causes an individual to feel unsteady, for example when standing or walking. It may be accompanied by feelings of giddiness, or wooziness, or having a sensation of movement, spinning, or floating. Balance is the result of several body systems working together: the visual system (eyes), vestibular system (ears) and proprioception (the body’s sense of where it is in space). Degeneration or loss of function in any of these systems can lead to balance deficits. […] Problems with balance can occur when there is a disruption in any of the vestibular, visual, or proprioceptive systems. Abnormalities in balance function may indicate a wide range of pathologies from causes like inner ear disorders, low blood pressure, brain tumors, and brain injury including stroke.
- #1 Balance System Disordershttps://www.asha.org/practice-portal/clinical-topics/balance-system-disorders/?srsltid=AfmBOopX6Qc0upw6OsKwMmE9fgh9kiLpl1VXY4oVa_0dGrKhZ-Lzlm7n
A functioning balance system allows a person to move through the environment without falling and to be aware of ones physical position in relation to gravity. The human balance system is complex. It includes input from and coordination of three sensory systems: vestibular, visual, and somatosensory. Disturbances to one or more of these systems may result in a balance system disorder, which can have a negative impact on balance and/or cause symptoms such as dizziness. […] The underlying causes of balance disorders and the resulting symptoms are many and varied. They include causes related to the vestibular system and causes related to other body systems and conditions. Conditions and events resulting in imbalance and/or dizziness may resolve spontaneously or may become chronic. […] Causes of balance system disorders may include, but not be limited to, the following: acute injury to the vestibular system, aging vestibular system, alcohol and/or drug ingestion, anatomic brain changes, autoimmune inner ear disease, benign paroxysmal positional vertigo (BPPV), circulatory or cardiovascular conditions, cochlear implant surgery, enlarged vestibular aqueduct syndrome, genetic disorders, infectious disease (viral or bacterial), inflammatory process of the inner ear, mal de dbarquement syndrome, medication side effects, Mnires disease, metabolic disorders, musculoskeletal conditions, neurological impairment/event/disease, otosclerosis, ototoxicity, peripheral neuropathy, persistent postural-perceptual dizziness, psychological disorders, space-occupying lesions of the auditory nerve, superior semicircular canal dehiscence, temporal bone fracture, traumatic brain injury, vestibular migraine and other migraine variants. […] A review of current literature indicates that the most common causes of dizziness in children are otitis media, migraine headache, benign paroxysmal vertigo of childhood, trauma, and vestibular neuritis.
- #1 In brief: How does our sense of balance work? – InformedHealth.org – NCBI Bookshelfhttps://www.ncbi.nlm.nih.gov/books/NBK279394/
The vestibular system is made up of three semicircular canals and two otolith organs, which are found diagonally under the semicircular canals. […] The otolith organs detect changes in speed of linear movements (in a straight line) for instance, when you fall, take an elevator, or accelerate or brake in a car. […] The vestibular system is especially sensitive in children, and reacts more slowly to movements as we grow older. Inner ear infections and other problems may also affect how well our sense of balance works.
- #1 Balance Disorders: An Overview – American Hearing Research Foundationhttps://www.american-hearing.org/disease/balance-disorders-an-overview/
These crystals are heavier than any of the other surrounding components of the ear. So, when the head tilts, gravity forces the crystals downward, causing a pull on the jelly-like layer and the sensory hair cells that it’s attached to. This pull sets off a signal from the hair cells that travels along the vestibular nerve to the brain for processing.
- #1 Dizziness & Balance Problems Related to Vision | Neuro-Optometric Rehabilitation Associationhttps://noravisionrehab.org/patients-caregivers/about-brain-injuries-vision/dizziness-balance-problems-related-to-vision
Vision plays a significant role in our ability to balance, orient ourselves in space, and process movement of things in our environment. […] If the vestibular system is damaged by disease, aging, head injury, or sometimes for no apparent reason, persons with a vestibular disorder often experience extreme difficulty with balance and movement, as well as with their perception of space. […] Common symptoms associated with vestibular disorders include: Imbalance and Spatial disorientation. […] Following are some common visual dysfunctions that may contribute to dizziness and balance problems: Aniseikonia – A visual condition where there is a significant difference in the perceived size of images, one eye to the other. This can cause disorientation, eyestrain, headache, and dizziness and balance disorders.
- #1 The Inner Ear: Understanding the Balance Systemhttp://healthlibrary.umcno.org/Library/DiseasesConditions/Adult/3,85837
Balance is a group effort of your eyes, inner ear, joints, and muscles. They each send signals to the brain about body position and head movement. The brain uses this information to balance the body. When you have an inner ear problem, the brain may get conflicting signals. This can cause symptoms, such as the feeling of spinning (vertigo). […] Inside the inner ear are three semicircular canals. Each canal contains tiny hairs, crystals, and fluid. These structures help the canals sense up-and-down, forward-and-backward, and side-to-side motion. Nerves carry the signals from the canals to the brain. […] Signals from all over your body travel to the brain. Once the signals arrive, the brain decides what they mean. Sometimes signals conflict. Have you ever sat on a stopped train and watched a moving train go by? When that happens, your eyes signal that you’re moving. But your inner ear and body signal that you’re still. The brain weighs conflicting data, such as this, and decides what’s true. The result is balance.
- #1 Balance Disorders â Causes, Types & Treatment | NIDCDhttps://www.nidcd.nih.gov/health/balance-disorders
A balance disorder can be caused by certain health conditions, medications, or a problem in the inner ear or the brain. […] Causes of balance problems include medications, ear infection, a head injury, or anything else that affects the inner ear or brain. […] Unfortunately, many balance disorders start suddenly and with no obvious cause. […] When the signals from any of these sensory systems malfunction, you can have problems with your sense of balance, including dizziness or vertigo. […] If you have additional problems with motor control, such as weakness, slowness, tremor, or rigidity, you can lose your ability to recover properly from imbalance.

Vertigo is a symptom — a feeling that either you or the space around you is spinning. Conditions that affect the inner ear cause it most often, but those that have an impact on the brain can also do it. […] A cold or flu virus, or sometimes bacteria, infect the maze of fluid-filled channels deep in your ear. This „labyrinth,” which normally helps you keep your balance, swells up, confuses your brain, and causes vertigo. […] A virus causes sudden swelling of the vestibular nerve that connects your inner ear and the brain. This could make you dizzy, unsteady, and sick to your stomach, but doesn’t normally cause hearing loss or tinnitus. […] Though rare, Meniere’s disease can cause serious vertigo that lasts from 20 minutes to several hours, often with nausea and vomiting. […] A blow to your head can tear a hole in the tissue that divides your air-filled middle ear from your fluid-filled inner ear. This can lead to balance problems.

Vertigo is not the same as being lightheaded. People with vertigo feel as though they are actually spinning or moving, or that the world is spinning around them. […] Peripheral vertigo is due to a problem in the part of the inner ear that controls balance. These areas are called the vestibular labyrinth, or semicircular canals. The problem may also involve the vestibular nerve. This is the nerve between the inner ear and the brain stem. […] Central vertigo is due to a problem in the brain, usually in the brain stem or the back part of the brain (cerebellum). […] The main symptom is a sensation that you or the room is moving or spinning. The spinning sensation may cause nausea and vomiting. […] Physical therapy may help improve balance problems. You’ll be taught exercises to restore your sense of balance. Exercises can also strengthen your muscles to help prevent falls. […] Vertigo can interfere with driving, work, and lifestyle.

Balance impairment is associated with increased fall risk. […] An impairment in any of these systems can result in a deficit in balance control. Such impairment may be due to specific pathology or the progressive decline of function in the course of normal aging. […] The combination of senescent decline in organ function and the higher prevalence of diseases of the balance control systems in older adults predisposes this population subset to balance impairment. […] Proprioceptive acuity declines with normal aging. […] Muscle strength is typically maintained at peak levels into the 5th or 6th decade. Thereafter, accelerated decline occurs, with as much as 50% lost by age 80. […] Lower extremity muscle weakness is highly correlated with fall risk in older adults. […] The integrity of balance function is essential for activities of daily living efficacy. Its deterioration with aging and disease places older adults at increased risk of falls and dependency. […] Central processing deteriorates with advancing age.
- #1 The balance system | Ménièreâs Societyhttps://www.menieres.org.uk/information-and-support/the-balance-system
The balance system works by coordinating information in your brain from the three senses used for balance: your balance organ in your inner ear, your eyes, the internal sense of position/movement in your body. […] If you feel dizzy, it means that your brain has not been able to coordinate the information from all the balance senses properly. This could be due to a problem in the brain or with any of the balance senses. […] In vestibular disorders (e.g. Mnires), the balance organ in the inner ear is affected. As the balance organ is faulty, the brain becomes more dependent on information coming from the eyes and sensors in your body. This makes you much more sensitive to situations which can cause dizziness, such as disorientating environments and times when you are under stress. Therefore, not all the symptoms of dizziness experienced will be due to the balance organ, some will be caused because your balance system cannot cope with the situation you are in.
- #1 Neurology Clinic – Clinical Website – Dr Michael Grosshttp://neurologyclinic.org.uk/articles/balance_disorders.html
The key message for all people who have suffered BPPV from whatever cause including trauma is that the more one treats the condition with specialised therapists, then the more likely the better outcome with a good prognosis. […] Disorders of the balance mechanism can be investigated by vestibular function tests. Although these tests are objective, they are limited in the way they can test the mechanism. […] The central nervous system is able to adopt a number of adapted mechanisms to cope with disturbances of the balance mechanism. If there is a combination of damage to the balance mechanism together with damage to other parts of the nervous system such as the cerebellum, reticular formation of the brain stem or spinal cord as can occur in head injury, then the disability can be much greater. This is because the compensatory mechanisms are less able to function. […] As indicated above, there is an urgent need for balance rehabilitation soonest after acute vertigo with nausea or vomiting has passed. There will be a natural compensation by the balance mechanism. Equally there will be ongoing natural recovery from any insult or injury.
- #1 The balance system | Ménièreâs Societyhttps://www.menieres.org.uk/information-and-support/the-balance-system
Dizziness and imbalance can also be the result of damage to areas of the brain that coordinate balance and are often the cause of dizziness in people who have multiple sclerosis, stroke or Parkinsons disease. […] In Mnires and other inner ear balance disorders, your brain must rely more on your sense of vision to balance more than people who do not have a balance disorder. As a result of this, your balance system can be more sensitive to confusing or disorienting information about your balance coming from your eyes. […] The balance system can also become overloaded when you take in more visual information than you are used to dealing with. Too much visual information can include motion, patterns or flickering lights. This visual information conflicts with information coming from your other balance senses resulting in dizziness and unsteadiness. […] When fewer signals are being sent from your body, your balance system is more reliant on the signals from your eyes and balance organ.
- #1 Balance problems: What are the causes? | Top Doctorshttps://www.topdoctors.co.uk/medical-articles/what-causes-balance-problems
The ability to balance depends on various factors. This includes on how well the brain, nerves, eyes, muscles and joints, function, as well as the vestibular system, which is the group of structures behind the ear drum. […] Leading consultant adult paediatric ENT surgeon Miss Victoria Alexander looks at the most common causes of balance problems in connection to the vestibular system, their symptoms and treatment. […] Balance disorders happen when your experience of body movement changes. […] Consequently, this can affect the ability to walk and how you interact in your day-to-day life. […] This condition can cause short episodes of dizziness when you move your head. Its caused by small crystals in the inner ear that become dislodged, for example after a head trauma or an inner ear infection.

- #1 Balance Disorders – National Dizzy & Balance Centerhttps://www.nationaldizzyandbalancecenter.com/resources/balance-disorders/
A balance disorder is a disturbance that causes an individual to feel unsteady, giddy, woozy, or have a sensation of movement, spinning, or floating. An organ in our inner ear, the labyrinth, is an important part of our vestibular (balance) system. The labyrinth interacts with other systems in the body, such as the visual (eyes) and skeletal (bones and joints) systems, to maintain the body’s position. These systems, along with the brain and the nervous system, can be the source of balance problems. […] Infections (viral or bacterial), head injury, disorders of blood circulation affecting the inner ear or brain, certain medications, and aging may change our balance system and result in a balance problem. Individuals who have illnesses, brain disorders, or injuries of the visual or skeletal systems, such as eye muscle imbalance and arthritis, may also experience balance difficulties. A conflict of signals to the brain about the sensation of movement can cause motion sickness (for instance, when an individual tries to read while riding in a car). Some symptoms of motion sickness are dizziness, sweating, nausea, vomiting, and generalized discomfort.

- #1 Falling Direction can Predict the Mechanism of Recurrent Falls in Advanced Parkinsonâs Disease | Scientific Reportshttps://www.nature.com/articles/s41598-017-04302-7
Falls are a common and disabling symptom in patients with Parkinsons disease (PD). For prevention, it is important to understand the pathophysiology of falls in PD patients, but the predictors for the possible mechanisms underlying such falls have not been clearly elucidated. […] Our results indicate that FOG and balance impairment are two major mechanisms for recurrent falling in PD patients, and falling direction is an important predictor for these mechanisms. […] In this study, we identified two major mechanisms underlying recurrent falls in PD patients; FOG and balance impairment. Similarly, FOG and balance impairment were also suggested as major factors related to falls in previous studies, but none of them investigated the relationship between the aforementioned mechanisms and falling direction.
- #1 Falling Direction can Predict the Mechanism of Recurrent Falls in Advanced Parkinsonâs Disease | Scientific Reportshttps://www.nature.com/articles/s41598-017-04302-7
We demonstrated FOG was predictor for falling forward. […] Therefore, to initiate walking, PD patients with FOG require wider posterior-to-anterior movements than those without FOG, and this wider movement in the forward direction can result in a forward fall. […] Based on these results, we suggest that the severity of FOG is important, and more severe FOG can cause more forward falls in PD patients. […] Therefore, balance function is crucial to avoiding falls, and prevention strategies focusing on postural instability, such as balance rehabilitation, could reduce falls in PD patients. […] Considering that balance ability is more needed when changing posture, PD patients with postural instability tend to fall during sitting/standing or turning. On the other hand, FOG is common when patients try to start walking or turn, so PD patients with FOG tend to fall forward during walking or turning. […] In conclusion, we demonstrated that FOG and balance impairment are two major mechanisms of recurrent falls in PD patients and suggest falling direction as an important and convenient predictor to identify the falling mechanism.
- #1 Balance and Walking – MS Australiahttps://www.msaustralia.org.au/symptom/balance-and-walking/
Problems with balance and walking may be the direct result of MS causing damage to parts of the nervous system responsible for mobility or may be caused indirectly by other MS symptoms. […] Its important to note that balance and walking are separate issues but may have a direct influence on each other. For instance, lesions in a certain part of the brain responsible for balance (the cerebellum) can lead specifically to a loss of balance, which can then lead to unsteadiness when walking. […] Walking problems can be caused by slowed or altered nerve conduction resulting in muscle weakness, spasm or spasticity (muscle stiffness) or extreme fatigue. […] Other MS symptoms that can impact on walking and balance and increase the risk of falling include pain, tremor, dizziness and vertigo and visual problems. […] There are several different approaches that may improve balance, including exercise, yoga, tai chi and Pilates. […] Treatment of walking problems varies depending on the cause.
- #1 Balance problems after stroke | Stroke Associationhttps://www.stroke.org.uk/stroke/effects/physical/balance-problems-after-stroke
A stroke can change the way your brain controls balance and you could feel unsteady or uncoordinated. […] There are some other causes of balance problems, and treating an underlying condition can help improve your balance. […] A stroke often causes weakness on one side of your body, which can make it difficult to balance. […] The second main factor affecting balance is loss of sensation in your affected side, particularly your legs. […] After a stroke, moving around and keeping your balance may require more concentration, which is hard work. […] Vision is an important part of balance. Vision problems are common after stroke. […] Spatial neglect, or inattention, means that your brain is not processing sensory information from one side. […] Some people experience the sensation that they are upright even when they are leaning heavily to their weak side, sometimes to the extent that they cannot sit up safely. This is called pusher syndrome.
- #1 Balance problems after stroke | Stroke Associationhttps://www.stroke.org.uk/stroke/effects/physical/balance-problems-after-stroke
People with ataxia have difficulty with controlling smooth movements. […] You may be left with vertigo if a stroke happens in your cerebellum or brainstem, the areas that control balance in the brain. […] Some medicines commonly prescribed after stroke can cause dizziness or weakness, including some high blood pressure medication. […] A range of other conditions not directly related to stroke can also cause dizziness and loss of balance. […] Improvement tends to be fastest in the first few days or weeks after stroke, but can continue slowly for months or even years. […] A physiotherapist can assess you.

The second most common cause is vestibular neuritis, an inflammatory disorder. With vestibular neuritis, the nerves that help with balance in your inner ear dont function normally because of inflammation. […] The third most common cause of dizziness is a condition called persistent postural-perceptual dizziness (PPPD). This disorder causes you to feel like youre floating or rocking and tends to be worse when you stand or are in a visually complex environment, like a crowded shopping center. […] PPPD develops after your brain undergoes a stressful or alarming event, like a migraine, panic attack, depressive episode, or passing out. Your stress hormones activate your flight or fight response, which can change how your brain perceives motion and space. […] Other common causes of balance disorders include: Vestibular migraine (migraine with dizziness), Acoustic neuroma (a benign tumor), Stroke or heart disease, Circulatory issues (e.g., low blood pressure; hypertension), Mnires disease, Spinal cord or brain injuries, Swelling in the inner ear (labyrinthitis), Low blood sugar, Dehydration, Pregnancy, Parkinsons disease, Multiple sclerosis, Peripheral neuropathy, Dementia and Alzheimers disease.

- #1 Balance Problems: Causes, Diagnosis & Improvement Tips – Harvard Healthhttps://www.health.harvard.edu/topics/balance
Balance problems often begin to appear in a person’s later years. […] Because so many parts of the body are involved in maintaining balance, balance disorders may arise from a wide range of conditions. […] A key area implicated in balance problems is the inner ear’s vestibular system. […] When these structures are damaged, or when vestibular nerve cells decrease with age, we are more likely to experience dizziness and vertigo. […] While aging can affect any of the above systems, so might prescription medications. […] Benign paroxysmal positional vertigo (BPPV), labyrinthitis, and Meniere’s disease are considered vestibular disorders because they are problems stemming directly from dysfunction within the vestibular system, a series of miniscule structures and nerves within the inner ear that send signals to the brain regarding the body’s orientation. […] But many other conditions can lead to a balance disorder. […] Diseases of the central nervous system, such as Parkinson’s, dementia, and multiple sclerosis, can all disrupt balance thanks to their effects on nerves and on the parts of the brain associated with body movements.

Balance disorders are disturbances that make us feel unsteady on our feet or dizzy, as though were moving, spinning, or floating. The dizziness can happen when were standing, sitting down, or lying down. […] Our balance is maintained by our eyes, ears, and proprioception, the bodys sense of where it is. Disturbances to any of those senses can affect our balance. […] Certain medical conditions can cause balance disorders. Other causes include medications, problems in the inner ear or eyes, brain injuries including strokes, or low blood pressure. […] Balance (vestibular) disorders encompass such things as dizziness, vertigo, disequilibrium, or a general sense of being unsteady on your feet. More than 25 million Americans are affected by balance disturbances. […] With the general decrease in balance that accompanies the aging process, it is essential that your dizziness or balance problems are not solely attributed to the normal consequences of aging until you undergo a thorough evaluation.
- #1 The Human Balance System – Vestibular Disorders Associationhttps://vestibular.org/article/what-is-vestibular/the-human-balance-system/the-human-balance-system-how-do-we-maintain-our-balance/
Maintaining balance depends on information received by the brain from the eyes, muscles and joints, and vestibular organs in the inner ear. When this system is disrupted by damage to one or more components through injury, disease, or the aging process you may experience impaired balance accompanied by other symptoms such as dizziness, vertigo, vision problems, nausea, fatigue, and concentration difficulties. […] Impaired balance can be accompanied by other symptoms such as dizziness, vertigo, vision problems, nausea, fatigue, and concentration difficulties. […] The complexity of the human balance system creates challenges in diagnosing and treating the underlying cause of imbalance. The crucial integration of information obtained through the vestibular, visual, and proprioceptive systems means that disorders affecting an individual system can markedly disrupt a persons normal sense of balance. Vestibular dysfunction as a cause of imbalance offers a particularly intricate challenge because of the vestibular systems interaction with cognitive functioning, and the degree of influence it has on the control of eye movements and posture.

- #2 Balance Disorders: An Overview – American Hearing Research Foundationhttps://www.american-hearing.org/disease/balance-disorders-an-overview/
The research that AHRF funds pertains to balance disorders related to the inner ear. […] Most balance disorders are linked to the vestibular system, which is contained within the labyrinth of the inner ear. […] The semi-circular canals and the otolith organs (the utricle and saccule) are the specific organs of the inner ear that must function properly for people to be able to maintain their sense of balance. […] A fluid called endolymph fills each of these canals and shifts when the head changes position. When the endolymph moves, it triggers receptors in the semi-circular canals to send signals to the brain, via the vestibular nerve, about the change in the head’s position. […] The otolith organs help with balance by responding to gravity. They sense linear acceleration vertically, as in an elevator, and horizontally, as in a car. Sensory hair cellsâreceptorsâare inside the utricle and saccule.

A balance disorder can be caused by conditions affecting one or more parts of this system. […] The vestibular system in each inner ear is made up of three semi-circular canals and two pockets, called the otolith organs, which together provide constant feedback to the cerebellum about head movement. […] The two otolith organs (called the saccule and utricle) send messages to the brain about body movement in a straight line (backwards and forwards or upwards and downwards) and also about where the head is in relation to gravity, such as tilting, leaning or lying down. These organs contain small crystals (otoconia) that are displaced during these movements to stimulate tiny hairs, which transmit the message via the vestibular, or balance nerve to the cerebellum.
