Zaburzenie przetwarzania słuchowego
Diagnostyka i diagnoza

Zaburzenie przetwarzania słuchowego (APD), zwane także centralnym zaburzeniem przetwarzania słuchowego (CAPD), to neurologiczne schorzenie charakteryzujące się deficytami w centralnym układzie nerwowym odpowiedzialnym za przetwarzanie informacji dźwiękowych, przy zachowanej normalnej wrażliwości słuchowej. Diagnoza APD opiera się na kompleksowej ocenie audiologicznej, obejmującej testy dyskryminacji słuchowej, przetwarzania czasowego, mowy dychotycznej, zdolności słyszenia w hałasie oraz testy elektrofizjologiczne. Kryterium diagnostycznym jest uzyskanie wyników o co najmniej 2 odchylenia standardowe poniżej średniej w minimum dwóch testach. W populacji dzieci w wieku szkolnym częstość występowania APD wynosi około 2-5%, natomiast u dorosłych, zwłaszcza starszych, może sięgać 23-76%. Wczesna diagnoza jest kluczowa dla wdrożenia odpowiedniej interwencji, która może poprawić funkcje słuchowe i wsparcie edukacyjne, zwłaszcza u dzieci. Diagnostyka wymaga interdyscyplinarnego podejścia, angażującego audiologów, logopedów, psychologów i otolaryngologów, ze względu na częste współwystępowanie APD z innymi zaburzeniami, takimi jak ADHD, dysleksja czy zaburzenia językowe.

Zaburzenie przetwarzania słuchowego (APD) – definicja i specyfika

Zaburzenie przetwarzania słuchowego (APD), znane również jako centralne zaburzenie przetwarzania słuchowego (CAPD), to schorzenie neurologiczne wpływające na sposób, w jaki mózg przetwarza informacje dźwiękowe12. Jest to zaburzenie słyszenia spowodowane nieprawidłowym funkcjonowaniem części mózgu odpowiedzialnej za przetwarzanie dźwięków3. W typowym słyszeniu ośrodek słuchowy mózgu przekształca fale dźwiękowe wysyłane z uszu w rozpoznawalne dźwięki, jednak u osób z APD część słuchowa mózgu nie jest w stanie tego prawidłowo wykonać4.

Kluczowe jest zrozumienie, że APD nie jest wynikiem utraty słuchu – osoby z tym zaburzeniem zazwyczaj mają normalną wrażliwość słuchową56. APD wpływa na zdolność mózgu do przetwarzania informacji słuchowych, a nie na zdolność ucha do wykrywania dźwięków7. APD definiuje się jako zaburzenie w przetwarzaniu informacji słuchowych w ośrodkowym układzie nerwowym (nie spowodowane wyższymi funkcjami językowymi, poznawczymi lub innymi czynnikami), które można zdiagnozować na podstawie słabych wyników w jednej lub więcej umiejętności, takich jak: lokalizacja i lateralizacja dźwięków, dyskryminacja słuchowa, rozpoznawanie wzorców słuchowych, aspekty czasowe słyszenia czy zdolność rozumienia mowy w trudnych warunkach akustycznych8.

Epidemiologia zaburzeń przetwarzania słuchowego

Zaburzenie przetwarzania słuchowego dotyka ludzi w różnym wieku, choć najczęściej jest diagnozowane u dzieci w wieku szkolnym. Według szacunków Hearing Health Foundation, około 5% (2,5 miliona) dzieci w wieku szkolnym w USA doświadcza APD, podczas gdy niektórzy badacze szacują, że rzeczywista liczba może wynosić nawet do 12% populacji1. Inne źródła podają, że APD wpływa na około 3-5% dzieci w wieku szkolnym2.

W Polsce problem ten dotyczy około 2-3% dzieci w wieku 7-14 lat3. Badania z 2021 roku opublikowane w Frontiers in Neurology wykazały, że częstość występowania APD wynosiła 1,94 na 1000 dzieci według retrospektywnego badania z 2016 roku opartego na skierowaniach i diagnozach w krajowej klinice audiologicznej4. APD występowało u 5% dzieci i 0,9% dorosłych w każdym wieku, którzy zostali skierowani do ogólnej kliniki audiologicznej5.

APD jest często diagnozowane jako wtórne u dzieci z autyzmem6. Szacuje się również, że około 15% weteranów wojskowych cierpi na APD z powodu ekspozycji na wybuchy7. Osoby starsze, w tym te z typowym lub prawie typowym słuchem, mogą wykazywać deficyty w centralnym przetwarzaniu słuchowym związane z wiekiem8. U dorosłych częstość występowania jest znacznie wyższa – według jednego z badań szacuje się, że 23-76% starszych dorosłych żyje z APD9.

Znaczenie wczesnej diagnozy zaburzeń przetwarzania słuchowego

Wczesna diagnoza APD jest niezwykle istotna, ponieważ umożliwia szybką interwencję i wsparcie1. Dzieci z APD są narażone na problemy ze słuchaniem i uczeniem się w domu i w szkole, jeśli ich stan nie zostanie zidentyfikowany i odpowiednio zarządzany2. Wczesne leczenie daje dzieciom z APD najlepszą szansę na poprawę słuchania i uzyskanie wsparcia w nauce w szkole3.

Identyfikacja symptomów i dostęp do diagnozy oraz leczenia we wczesnym etapie może pomóc zmniejszyć objawy APD4. U osób dorosłych APD może prowadzić do problemów komunikacyjnych, słabych umiejętności społecznych, depresji i wpływać na codzienne funkcjonowanie podobnie jak u osób z utratą słuchu5.

Należy zaznaczyć, że diagnoza APD pozostaje kontrowersyjna, głównie ze względu na rzekome współwystępowanie z powiązanymi schorzeniami, takimi jak ADHD, trudności w uczeniu się i zaburzenia mowy-języka, a także ze względu na różnorodność objawów związanych z tym zaburzeniem6. Dlatego kompleksowa ocena przez interdyscyplinarny zespół specjalistów jest kluczowa dla prawidłowej diagnozy i zarządzania APD.

Specjaliści uprawnieni do diagnozowania zaburzeń przetwarzania słuchowego

Zaburzenie przetwarzania słuchowego (APD) jest diagnozowane wyłącznie przez audiologów posiadających specjalistyczne przeszkolenie w zakresie oceny centralnej funkcji słuchowej12. Audiolog jest jedynym klinicystą, który może postawić diagnozę APD34. Jest to istotne, ponieważ tylko audiolog posiada odpowiednie kwalifikacje i narzędzia do przeprowadzenia specjalistycznych testów oceniających różne obszary funkcji słuchowej centralnego układu nerwowego.

Jednakże, zalecane jest podejście multidyscyplinarne, które zapewnia kompleksową ocenę. W procesie diagnostycznym mogą uczestniczyć również inni specjaliści:

  • Logopedzi – mogą przeprowadzić testy wskazujące na występowanie APD i pomóc w różnicowaniu między zaburzeniami językowymi lub fonologicznymi a APD5
  • Otolaryngolodzy (ENT) – specjaliści od uszu, nosa i gardła6
  • Psycholodzy – mogą ocenić funkcje poznawcze, uwagę i inne czynniki, które mogą wpływać na przetwarzanie słuchowe7
  • Pedagodzy – mogą dostarczyć cennych informacji na temat funkcjonowania dziecka w środowisku szkolnym8

Współpraca między audiologiem a logopedą może prowadzić do dokładniejszej diagnozy, ponieważ objawy APD mogą często nakładać się na inne zaburzenia, takie jak zaburzenia językowe9. Gdy logopeda i audiolog współpracują w procesie oceny, mogą rozróżnić zaburzenia językowe lub fonologiczne od APD, właściwie zidentyfikować APD i wszelkie współistniejące zaburzenia językowe oraz opracować odpowiednie plany leczenia10.

Ważne jest, aby pamiętać, że mimo cennych informacji dostarczanych przez multidyscyplinarny zespół w zrozumieniu ogólnych obszarów mocnych i słabych stron dziecka, żadne z narzędzi testowych używanych przez tych profesjonalistów nie są narzędziami diagnostycznymi dla APD, a rzeczywista diagnoza APD musi być postawiona przez audiologa11.

Wiek odpowiedni do diagnozowania APD

Istotnym czynnikiem w ocenie APD u dzieci jest wiek. Większość tradycyjnych testów APD wymaga, aby dziecko miało co najmniej 7 lub 8 lat12. Jest to spowodowane tym, że zmienność w funkcjonowaniu mózgu jest tak wyraźna u młodszych dzieci, że interpretacja testów może nie być możliwa3. Z tego powodu wiele dzieci nie jest diagnozowanych aż do pierwszej klasy lub później4.

Testy dla dzieci poniżej 7 roku życia nie są zalecane z kilku powodów:

  • Znaczna zmienność rozwojowa funkcji mózgu u młodszych dzieci5
  • Szeroki zakres normalnych różnic rozwojowych u młodszych dzieci6
  • Brak danych normatywnych dla materiałów testowych dla dzieci poniżej 7 lat7
  • Niedojrzałość ścieżek słuchowych u dzieci poniżej 7 lat8

Brytyjskie Towarzystwo Audiologiczne proponuje trzy typy APD: APD wtórne, APD nabyte i APD rozwojowe9. Dorosłym również można stawiać diagnozę APD, szczególnie gdy zaburzenie to pojawia się w wyniku chorób, urazów lub starzenia się10.

Metody diagnostyczne zaburzeń przetwarzania słuchowego

Diagnoza zaburzenia przetwarzania słuchowego (APD) opiera się na kompleksowym podejściu, które obejmuje szereg testów i ocen. Nie istnieje standardowy proces diagnozowania APD1, a różne towarzystwa audiologiczne na całym świecie opublikowały własne wytyczne dotyczące APD2.

Wywiad kliniczny i ocena wstępna

Proces diagnostyczny rozpoczyna się od dokładnego wywiadu klinicznego, który obejmuje:

  • Historię prenatalną i porodową3
  • Historię medyczną4
  • Historię otologiczną (w tym infekcje uszu lub operacje)5
  • Status słuchu6
  • Umiejętności poznawcze7
  • Współistniejące schorzenia8
  • Umiejętności komunikacyjne9
  • Status edukacyjny10

Istotne jest również przeprowadzenie kompleksowej oceny audiologicznej (CAE) dla wszystkich osób podejrzewanych o APD, ponieważ nawet niewielka utrata słuchu może powodować trudności podobne do tych powszechnie związanych z APD11.

Testy audiologiczne specyficzne dla APD

Po potwierdzeniu normalnej wrażliwości słuchowej, audiolog przeprowadza serię testów w dźwiękoszczelnym pomieszczeniu12. Testy te mają na celu ocenę różnych aspektów centralnego przetwarzania słuchowego:

  • Testy dyskryminacji słuchowej – oceniają zdolność rozróżniania podobnych dźwięków13
  • Testy przetwarzania czasowego i wzorców słuchowych – badają zdolność rozpoznawania i różnicowania wzorców dźwiękowych14
  • Testy mowy dychotycznej – oceniają zdolność przetwarzania różnych informacji słuchowych prezentowanych jednocześnie do obu uszu15
  • Testy mowy monoauralnej o niskiej redundancji – badają zdolność rozumienia mowy w trudnych warunkach akustycznych16
  • Testy interakcji binauralnej – oceniają, jak dobrze oba uszy współpracują w przetwarzaniu informacji słuchowych17
  • Testy zdolności słyszenia w hałasie – badają zdolność rozumienia mowy w obecności hałasu tła18
  • Testy domknięcia słuchowego – oceniają zdolność wypełniania luk w mowie19
  • Testy lokalizacji dźwięku – badają zdolność identyfikacji kierunku dźwięków20

Dodatkowo, mogą być stosowane testy elektrofizjologiczne, które mierzą odpowiedzi nerwów między uszami a mózgiem na dźwięki21. Komputer rejestruje, jak nerwy między uszami a mózgiem reagują na dźwięki, co pokazuje, jak dobrze dźwięk przemieszcza się wzdłuż nerwów łączących uszy z mózgiem22.

Kryteria diagnostyczne i interpretacja wyników

Według Amerykańskiej Akademii Audiologii, diagnoza APD może być postawiona, gdy osoba uzyskuje wyniki o dwa odchylenia standardowe lub więcej poniżej średniej w co najmniej jednym uchu w dwóch lub więcej testach z baterii1. Jednakże, nie istnieje uniwersalnie przyjęty zestaw kryteriów diagnostycznych dla APD2.

Interpretacja wyników testów APD może być często trudna, jednak postępowanie zgodnie z pewnymi zalecanymi wytycznymi może ułatwić analizę wyników testów3. Rekomendowany jest model buffalo i inne modele do klasyfikacji wyników testów słuchowych4:

  • Model Buffalo wykorzystuje pojedynczy test centralnego słuchu (Staggered Spondaic Word) z wielowymiarowym punktowaniem i opiera się na 40 czynnikach5
  • Model Bellis/Ferre (stworzony w 1992 roku) służy do klasyfikacji wyników wielu testów słuchowych6
  • Model przetwarzania języka mówionego (SL-P) (Medwetsky, 2002) to model Buffalo z dodanymi elementami prozodycznymi i pamięci zanikającej7

Zaburzenie jest zazwyczaj diagnozowane, gdy osoba ma deficyt w co najmniej dwóch obszarach ocenianych podczas testowania8. Potwierdzenie wstępnej diagnozy jest ustanawiane, jeśli wyniki co najmniej trzech z testów opisanych w metodologii nie są prawidłowe9.

Najnowsze kliniczne wytyczne zostały ustanowione przez Amerykańską Akademię Audiologii (AAA) i dotyczą diagnozy, leczenia i zarządzania dziećmi i dorosłymi z (C)APD10. Zaleca się, aby tylko dzieci i dorośli z normalnymi zdolnościami poznawczymi byli uważani za kandydatów do oceny (C)AP11.

Diagnostyka różnicowa

Diagnostyka różnicowa jest kluczowa w procesie diagnozowania APD, ponieważ wiele innych zaburzeń może mieć podobne objawy. APD często współwystępuje z innymi zaburzeniami, co może komplikować diagnozę1:

  • Dysleksja2
  • Trudności w uczeniu się3
  • Obwodowa utrata słuchu4
  • Zaburzenie przetwarzania sensorycznego5
  • Zaburzenie ze spektrum autyzmu (ASD)6
  • Zaburzenie pragmatyki społecznej7
  • Specyficzne zaburzenie językowe (SLI)8
  • Niewerbalne trudności w uczeniu się9
  • ADHD10

Diagnozowanie APD może być trudne, ponieważ często pojawia się wraz z innymi schorzeniami, takimi jak ADHD czy dysleksja. Zrozumienie różnic jest kluczowe: APD koncentruje się na trudnościach w przetwarzaniu informacji słuchowych, mimo normalnego słuchu; ADHD wiąże się z wyzwaniami w utrzymaniu uwagi, kontrolowaniu impulsów i zarządzaniu koncentracją; Dysleksja wpływa na zdolność rozpoznawania i przetwarzania języka pisanego11.

Dane z oceny mogą identyfikować obecność zaburzeń o objawach podobnych do APD (np. obwodowa utrata słuchu, ADHD, zaburzenia mowy-języka, deficyty poznawcze, zaburzenie widma neuropatii słuchowej)12. Ważne jest również wykluczenie innych potencjalnych schorzeń przed postawieniem diagnozy APD13.

Oznaczenie diagnostyczne zaburzeń przetwarzania słuchowego

Centralne zaburzenie przetwarzania słuchowego (CAPD) jest odrębną i zdefiniowaną diagnozą w międzynarodowej klasyfikacji chorób ICD-10CM, z kodem H93.2512. Odnosi się do deficytów w przetwarzaniu informacji w centralnym układzie nerwowym słuchu (CANS)3.

Zaburzenie przetwarzania słuchowego nie jest wymienione w Podręczniku Diagnostycznym i Statystycznym Zaburzeń Psychicznych (DSM-5) Amerykańskiego Towarzystwa Psychiatrycznego. Jednak objawy powszechnie związane z APD mają tendencję do zaliczania się do kategorii diagnozy zaburzeń językowych DSM-54.

W Stanach Zjednoczonych APD jest uznawane za specyficzną niepełnosprawność w uczeniu się zgodnie z Ustawą o Edukacji Osób Niepełnosprawnych (IDEA). Kwalifikuje to ucznia do rozsądnych usług i udogodnień w szkole, jeśli zostało zdiagnozowane przez audiologa56.

Istnieje pewna kontrowersja dotycząca APD. Niektórzy eksperci nie zgadzają się, że jest to oddzielne zaburzenie, a istnieją różne definicje7. APD nie ma uniwersalnego uznania jako diagnoza8 i nie ma kodu ICD-9 dla APD w Międzynarodowej Klasyfikacji Chorób CDC9.

Polityka Aetna dotycząca APD opiera się na ograniczonych dowodach na APD jako odrębną jednostkę patofizjologiczną, na braku dowodów na ustalone kryteria i dobrze zweryfikowane instrumenty do diagnozowania APD i wiarygodnego odróżnienia go od innych stanów wpływających na słuchanie i/lub rozumienie języka mówionego, oraz na braku dowodów z dobrze zaprojektowanych badań klinicznych dowodzących skuteczności interwencji w leczeniu APD10.

Trudności i wyzwania w diagnostyce zaburzeń przetwarzania słuchowego

Diagnozowanie zaburzenia przetwarzania słuchowego (APD) wiąże się z wieloma wyzwaniami i trudnościami, co przyczynia się do kontrowersji wokół tego zaburzenia. Główne problemy diagnostyczne obejmują:

Brak standardowych kryteriów diagnostycznych

Jednym z głównych wyzwań jest brak jasno ustalonych, standardowych kryteriów diagnostycznych dla APD1. Nie ma powszechnej zgody co do „złotego standardu” baterii testów do oceny tego zaburzenia2. Powoduje to znaczne różnice w diagnozach między klinicystami. W badaniu z próbką dokumentacji 150 dzieci w wieku szkolnym, które ukończyły co najmniej cztery testy CAPD, wskaźniki diagnoz wahały się od 7,3% do 96% w zależności od stosowanych kryteriów3.

Brak jest również jednolitych kryteriów dotyczących tego, jakie testy przeprowadzać, ile odchyleń standardowych pacjent musi mieć, aby się zakwalifikować, a nawet kto jest dobrym kandydatem do testowania (C)APD4. To powoduje, że diagnoza APD może być subiektywna i nieprecyzyjna.

Współistnienie z innymi zaburzeniami

APD często współwystępuje z innymi zaburzeniami, co utrudnia diagnozę różnicową5. Często zgłaszane współwystępowanie APD z innymi zaburzeniami wpływającymi na słuchanie i/lub rozumienie języka mówionego sugeruje, że APD nie jest w rzeczywistości odrębną jednostką kliniczną6.

Audiologiczne dane oceniające mogą identyfikować obecność zaburzeń o objawach podobnych do APD, takich jak obwodowa utrata słuchu, ADHD, zaburzenia mowy-języka, deficyty poznawcze czy zaburzenie widma neuropatii słuchowej7. Te nakładające się symptomy mogą prowadzić do błędnej diagnozy lub nierozpoznania APD.

Problemy metodologiczne w testowaniu

Testowanie APD wymaga, aby dziecko miało co najmniej 7 lat, co opóźnia diagnozę dla młodszych dzieci8. Jest to problematyczne, ponieważ wczesna interwencja jest kluczowa dla optymalnych wyników9.

Nawet jeśli jeden nieprawidłowy wynik z testów opisanych w metodologii wystarczy do rozpoznania APD, zarówno jego czułość, jak i swoistość jest niska10. Może to prowadzić do fałszywie pozytywnych lub fałszywie negatywnych diagnoz.

Ponadto, metody używane do testowania APD muszą uwzględniać, że każda forma oceny słuchu bada zarówno przetwarzanie sensoryczne, jak i poznawcze11. Ignorowanie aspektów poznawczych może prowadzić do nieprecyzyjnych diagnoz.

Kontrowersje naukowe

Istnieją znaczące kontrowersje naukowe dotyczące konstruktu APD12. Niektórzy badacze kwestionują, czy APD jest odrębnym zaburzeniem klinicznym13.

Błędne przekonanie, które wydaje się leżeć u podstaw wielu fundamentów APD, polega na tym, że pogorszone funkcjonowanie słuchowe u osoby z normalnym audiogramem musi być spowodowane zaburzeniami przetwarzania w centralnym układzie słuchowym14.

Ponadto, istnieje problem z terminem „zaburzenie przetwarzania słuchowego” (APD), ponieważ problemy, które próbuje opisać, nie ograniczają się do centralnego układu słuchowego15.

Wpływ tych wyzwań na diagnozę i leczenie

Audiolog może opracować kategorie diagnostyczne „Słabość”, ponieważ duża liczba skierowanych dzieci ma wyraźne problemy, ale nie spełnia kryteriów AAA/ASHA do diagnozy „Zaburzenia”16.

Prosta diagnoza APD oparta na obecnych wytycznych nie jest ani realistyczna, biorąc pod uwagę obecnie stosowane testy, ani odpowiednia, zgodnie z oceną audiologów świadczących usługi17.

Te wyzwania diagnostyczne podkreślają potrzebę współpracy między specjalistami, aby w pełni zrozumieć zachowania wykazywane przez dzieci prezentujące trudności w słuchaniu18.

Typowe objawy zaburzeń przetwarzania słuchowego

Osoby z zaburzeniem przetwarzania słuchowego (APD) mogą wykazywać różnorodne objawy, które mogą wpływać na ich zdolność do przetwarzania i rozumienia dźwięków, mimo normalnego słuchu. Amerykańska Akademia Audiologii (AAA) i Amerykańskie Stowarzyszenie Mowy-Języka-Słuchu (ASHA) wymieniają następujące częste objawy APD1:

  • Trudności w rozumieniu mowy w obecności hałasu tła2
  • Trudności w rozumieniu szybkiej, niewyraźnej lub zniekształconej mowy3
  • Częste prośby o powtórzenie tego, co zostało powiedziane (mówienie „hm?” i „co?”)4
  • Trudności w podążaniu za ustalnymi wskazówkami lub poleceniami5
  • Błędne interpretowanie sarkazmu lub żartów6
  • Rozpraszalność7
  • Trudności akademickie, w tym problemy z czytaniem, pisownią i uczeniem się8
  • Trudności w utrzymaniu uwagi9
  • Trudności w lokalizowaniu dźwięku10

Według nowozelandzkich wytycznych dotyczących zaburzeń przetwarzania słuchowego (2017), następująca lista kluczowych objawów APD lub chorób współistniejących może być używana do identyfikacji osób, które powinny zostać skierowane na badanie audiologiczne i ocenę APD11:

  • Trudności w śledzeniu ustnych wskazówek, chyba że są krótkie i proste12
  • Trudności w koncentracji uwagi i zapamiętywaniu informacji mówionych13
  • Powolność w przetwarzaniu informacji mówionych14
  • Trudności w rozumieniu w obecności innych dźwięków15
  • Przytłoczenie złożonymi lub „zatłoczonymi” środowiskami dźwiękowymi, np. klasami szkolnymi, centrami handlowymi16
  • Słabe umiejętności słuchania17
  • Niewrażliwość na ton głosu lub inne niuanse mowy18
  • Nabyty uraz mózgu19
  • Historia częstej lub przewlekłej choroby ucha środkowego (zapalenie ucha środkowego, „ucho klejowe”)20

Najczęstsze objawy wśród pacjentów, u których zdiagnozowano APD, to: późny rozwój mowy (96%), wady wymowy (91,4%), problemy z nauką języka (91,67%)21. Najczęstszym problemem wśród pacjentów zdiagnozowanych z APD jest opóźniony rozwój mowy w dzieciństwie, problemy w szkole (głównie w nauce języków i matematyki), zaburzenia mowy i opóźnienia22.

Osoby dorosłe z APD często zgłaszają, że słyszą, ale czasami mają trudności ze zrozumieniem tego, co słyszą23. APD może szczególnie wpływać na rozumienie w trudnych sytuacjach słuchowych, takich jak w obecności innych rozpraszających dźwięków lub podczas słuchania złożonych informacji24.

Ważne jest, aby pamiętać, że te i inne częste objawy APD nie są unikalne dla APD i nie powinny być traktowane jako definitywne znaki, że APD jest obecne25. Również należy zauważyć, że u dzieci APD może współistnieć z innymi zaburzeniami, w tym językowymi, czytania, uczenia się lub deficytu uwagi26.

Podsumowanie procesu diagnostycznego zaburzeń przetwarzania słuchowego

Proces diagnostyczny zaburzenia przetwarzania słuchowego (APD) wymaga kompleksowego podejścia multidyscyplinarnego, którego celem jest dokładne zidentyfikowanie i scharakteryzowanie zaburzenia. Poniżej przedstawiono kluczowe elementy procesu diagnostycznego:

Kluczowe etapy procesu diagnostycznego

  1. Wstępna ocena i wywiad: Proces rozpoczyna się od szczegółowego wywiadu dotyczącego historii przypadku i objawów1. Zbierane są informacje na temat historii prenatalnej, porodowej, medycznej, otologicznej, słuchowej, poznawczej oraz edukacyjnej2.
  2. Podstawowe badanie słuchu: Audiolog przeprowadza standardowe badanie słuchu, aby wykluczyć utratę słuchu jako przyczynę trudności3.
  3. Specjalistyczne testy APD: Jeśli wykluczono utratę słuchu, audiolog przeprowadza serię specjalistycznych testów w dźwiękoszczelnym pomieszczeniu, które oceniają różne aspekty centralnego przetwarzania słuchowego4. Są to testy behawioralne i elektrofizjologiczne5.
  4. Ocena interdyscyplinarna: W zależności od potrzeb, mogą być zaangażowani inni specjaliści, tacy jak logopedzi, psycholodzy czy pedagodzy, którzy przeprowadzają dodatkowe oceny67.
  5. Interpretacja wyników: Audiolog analizuje wyniki wszystkich testów i ocen, aby określić, czy pacjent spełnia kryteria diagnostyczne APD8.
  6. Diagnoza i określenie typu APD: Po postawieniu diagnozy, określany jest charakter zaburzenia, aby można było zalecić zindywidualizowane działania zarządzające i terapeutyczne, które będą odpowiadać konkretnym obszarom trudności9.

Narzędzia i metody diagnostyczne

Bateria testów używanych w ocenie APD może obejmować10:

  • Testy przetwarzania czasowego słuchowego11
  • Testy przetwarzania wzorców słuchowych12
  • Testy separacji binauralnej13
  • Testy integracji binauralnej14
  • Testy wydajności słuchowej z degradowanymi sygnałami akustycznymi15

Testy stosowane w ocenie APD mogą się różnić w zależności od objawów prezentowanych przez pacjenta16. Z tego powodu kody oceny APD (92620 i 92621) są kodami czasowymi, które pozwalają audiologom na elastyczność w wykorzystaniu najbardziej odpowiednich miar dla każdej indywidualnej sytuacji17.

Indywidualizacja podejścia diagnostycznego

Proces diagnostyczny powinien być zindywidualizowany dla każdego pacjenta1. Badania powinny być uszeregowane hierarchicznie, aby umożliwić sukcesywne badanie konkretnych hipotez dotyczących charakteru problemów dziecka2.

Audiolog może dostosować baterie testów w zależności od wieku, objawów, statusu poznawczego i innych czynników3. Ta elastyczność jest kluczowa, ponieważ nie ma jednego podejścia diagnostycznego, które byłoby odpowiednie dla wszystkich dzieci z APD4.

Wyzwania diagnostyczne

Pomimo postępów w dziedzinie diagnostyki APD, nadal istnieją znaczące wyzwania1:

  • Brak uniwersalnie przyjętej metody przesiewowej dla APD2
  • Kontrowersje dotyczące etiologii, prezentacji i diagnozy APD, szczególnie w populacji osób dorosłych3
  • Brak ustalonych wytycznych dotyczących skierowań na ocenę APD podczas rutynowych wizyt audiologicznych4
  • Ograniczenia w testowaniu młodszych dzieci (poniżej 7 lat)5

Potrzebne jest szybkie narzędzie przesiewowe, aby informować o skierowaniach na kompleksowe testy APD6. Na podstawie badań, WIN, QuickSIN lub RDDT mogą być przydatnymi narzędziami przesiewowymi do motywowania skierowania na kompleksowe testy APD7.

Znaczenie wczesnej i dokładnej diagnozy

Wczesna diagnoza jest niezwykle ważna, ponieważ jeśli stan nie zostanie zidentyfikowany i leczony wcześnie, dziecko jest narażone na problemy ze słuchaniem i uczeniem się w domu i w szkole1.

Niezależnie od tego, ile objawów APD ma dziecko, tylko staranna i dokładna diagnoza może określić, czy rzeczywiście obecne jest APD2. Diagnoza APD nie może być postawiona na podstawie listy kontrolnej objawów34.

Dokładna diagnoza jest kluczowa dla właściwego leczenia5. Im bardziej specyficzna diagnoza, tym bardziej specyficzne leczenie, co zwykle oznacza lepsze i dłużej trwające wyniki leczenia6.

Audiologiczna diagnoza APD powinna być podstawą do opracowania zindywidualizowanego planu leczenia, który odpowiada specyficznym potrzebom każdego pacjenta78.

Przyszłe kierunki w diagnostyce zaburzeń przetwarzania słuchowego

W dziedzinie diagnostyki zaburzeń przetwarzania słuchowego (APD) prowadzone są intensywne badania nad nowymi technikami obrazowania, które mogłyby być wykorzystane w przyszłości do właściwej diagnozy APD1. Ze względu na jego wyniszczający wpływ i nakładanie się z innymi zaburzeniami neurorozwojowymi, istnieje pilna potrzeba opracowania narzędzi i kryteriów do odpowiedniej diagnozy2.

Do tej pory żadne badania nie zgłosiły rutynowego stosowania obrazowania w diagnozie APD3, co wskazuje na obszar, który wymaga dalszych badań i rozwoju. Przyszłe badania powinny skupić się na opracowaniu bardziej obiektywnych i standaryzowanych metod diagnostycznych.

Istnieje również potrzeba lepszego zrozumienia związku między APD a innymi zaburzeniami, takimi jak ADHD, dysleksja czy zaburzenia językowe. Badacze sugerują, że audiologowie powinni współpracować z innymi specjalistami, aby pełniej zrozumieć zachowania przejawiające się u dzieci prezentujących trudności w słuchaniu4.

Przyszłe podejścia diagnostyczne mogą obejmować zarówno testy behawioralne, jak i elektrofizjologiczne, a także nowe technologie obrazowania mózgu, aby zapewnić bardziej kompleksową i dokładną ocenę funkcji słuchowej centralnego układu nerwowego.

Szczególnie obiecujące jest wykorzystanie potencjałów korowych jako części baterii testów, gdy jest to właściwe5. Dodatkowe badania w tym obszarze mogą prowadzić do bardziej niezawodnych i ważnych diagnostycznie miar APD.

Wreszcie, istnieje potrzeba opracowania szybkich i dokładnych narzędzi przesiewowych, które mogą być stosowane podczas rutynowych wizyt audiologicznych, aby identyfikować pacjentów, którzy mogą potrzebować pełnej oceny APD6. Takie narzędzia mogłyby znacznie poprawić wczesną identyfikację i interwencję w przypadku APD.

    Auditory processing disorder, also called APD, is a type of hearing loss caused by something affecting the part of the brain that processes how you hear. […] APD is also sometimes called central auditory processing disorder (CAPD). […] The cause of auditory processing disorder (APD) is sometimes unknown. […] In typical hearing, the brain’s auditory center takes the sound waves sent from the ears and turns them into sounds you know. But with auditory processing disorder (APD), the auditory part of the brain can’t do this. […] If you have trouble hearing or understanding what you hear, talk to a health care professional.

    APD can affect people of all ages, but it is most common in school-aged children. According to the Hearing Health Foundation, approximately 5% (2.5 million) of school-aged children in the US experience APD, while researchers estimate the real number could be up to 12% of the population. […] APD in children is often missed because the child’s hearing assessments show normal or near normal hearing, which is why Denton Hearing Health Care makes the extra effort to test for and treat auditory processing disorder in both children and adults whenever it is suspected. […] The disorder is usually most noticeable when there is a lot of background noise, multiple conversations taking place at the same time, or the individual is not facing the speaker. […] Because APD causes most to assume that the person is experiencing hearing challenges when hearing tests are normal, many doctors fail to identify the cause.

    Auditory processing disorder (APD) is a hearing problem that affects about 3%5% of school-aged children. […] Early diagnosis is important. If the condition is not identified and managed early, a child is at risk for listening and learning problems at home and school. […] If you think your child is having trouble hearing or understanding when people talk, have an audiologist (hearing specialist) examine your child. Only audiologists can diagnose auditory processing disorder. […] The most common way to diagnose APD is to use a specific group of listening tests. […] Most traditional APD tests require a child to be at least 7 years old. So, many kids aren’t diagnosed until first grade or later. […] APD is not technically considered a learning disability, and kids with APD usually aren’t put in special education programs. Depending a child’s degree of difficulty in school, they may be eligible for an accommodation plan such as an individualized education program (IEP) or a 504 plan that would outline any special needs for the classroom.

    https://nwauditoryprocessing.com/services-what-is-apd/
    Auditory Processing Disorder (APD), also commonly referred to as Central Auditory Processing Disorder (CAPD), is the inability to attend to, discriminate among or between, recognize, or understand auditory information. APD is a sensory processing deficit that commonly impacts listening, spoken language, comprehension, and learning. APD is associated with some sort of dysfunction within the central auditory nervous system. […] APD, also referred to as central auditory processing disorder (CAPD), is diagnosed by an audiologist who has received specialized training in the evaluation of central auditory function. My goals for each individual are accomplished by an accurate diagnosis coupled with a treatment/therapy regime targeted to remediate the identified auditory processing deficits. A battery of normed tests is essential to assess the six areas of potential processing deficits, yielding a profile that outlines auditory strengths and weaknesses.

    Auditory processing is the brain’s ability to accurately perceive speech in both quiet and noisy settings. The brain can detect and analyze small differences in pitch, loudness, and duration. Some children with normal hearing have difficulty with this ability, leading to problems with discriminating speech. This is a (central) auditory processing disorder or (C)APD. (C)APD can impact the listener’s ability to develop language, succeed academically, and/or communicate effectively. […] Audiologists are uniquely trained to administer specific diagnostic tests to diagnose (C)APD. These tests are designed to assess the maturity of the auditory neural pathways, from ear to brain, with performance compared to age based normative data. History information is collected and includes results of other/multidisciplinary assessment to assist with differential diagnosis. Testing includes assessment of hearing sensitivity. […] Diagnosis should be individualized, with the nature of disorder based on patterns of performance. Performance may be monitored over time as the neural pathways mature.

    CAPD, a distinct and defined diagnosis (ICD-10CM Code: H93.25), refers to deficits in the processing of information in the central auditory nervous system (CANS). […] CAPD assessment typically results in appropriate diagnoses of the specific auditory process or processes that are deficient. […] Only audiologists who have undergone extensive training in this professional area should undertake the evaluation and diagnosis of CAPD. […] In terms of diagnosis, a test battery approach, using behavioral tests with high sensitivity and specificity, and possibly electrophysiological tests as well, are favored. […] In conclusion, it is essential that remediation of aspects of CAPD be prescribed by the audiologist, based upon assessment and tailored to the specific deficits demonstrated, as well as the learning and language needs of a given individual.

    Auditory processing disorder (APD), a neurological condition also known as central auditory processing disorder (CAPD), affects the brain’s ability to process auditory input, making it difficult to understand speech, follow oral instructions, or distinguish speech in noisy environments. […] Though APD awareness has increased in recent years, confusion about the disorder abounds. It can appear simultaneously with conditions such as attention deficit/hyperactivity disorder, so it’s important that those with APD symptoms get evaluated by an audiologist for proper diagnosis. […] A trained audiologist is uniquely qualified to diagnose APD. In addition to conducting an initial exam to ensure the ears are healthy and to rule out hearing acuity problems, the audiologist performs special tests to assess the brain’s various auditory processing functions. The specific selection of tests will depend on the patient’s age, symptoms, cognitive status, and other factors.

    Auditory processing disorder (APD) is a hearing problem that affects about 3%5% of school-aged children. […] Early diagnosis is important. If the condition is not identified and managed early, a child is at risk for listening and learning problems at home and school. […] If you think your child is having trouble hearing or understanding when people talk, have an audiologist (hearing specialist) examine your child. Only audiologists can diagnose auditory processing disorder. […] The most common way to diagnose APD is to use a specific group of listening tests. […] Most traditional APD tests require a child to be at least 7 years old. So, many kids aren’t diagnosed until first grade or later. […] APD is not technically considered a learning disability, and kids with APD usually aren’t put in special education programs. Depending a child’s degree of difficulty in school, they may be eligible for an accommodation plan such as an individualized education program (IEP) or a 504 plan that would outline any special needs for the classroom.

    https://silverliningsclinic.com/blog/auditory-processing-disorder-apd-frequently-asked-questions
    Why would I want to get tested for APD? APD is a difficult disorder to diagnose, and many children and adults may have deficits in listening skills. Testing can help you identify your child’s or your key issue and help you pursue more appropriate services. The more specific the diagnosis, the more specific the treatment. More specific treatment usually means that there are better and longer lasting results from treatment. School systems and colleges often require a diagnosis of APD to provide accommodations in classrooms. […] How is it treated? The treatment of APD is generally broken into 3 approaches: Environmental modifications: This approach improves access to the auditory information by changing the environment to allow the individual to process it more easily. An example may be using amplification systems or even having the teacher write out instructions on the board to supplement spoken directions. Compensatory strategies: This approach focuses on teaching the individual how to use problem solving skills to overcome the APD. An example may be learning to listen actively. Targeting the APD itself: This approach works on each area that the individual with APD struggles with. Some programs are computer-based while others may be provided in therapy settings. An example may be a task to work on speech-in-noise training to help the individual more easily separate noise from the important information they need to listen for.

    Central Auditory Processing Disorder (CAPD) is a condition that children can be born with or develop over time. […] its only after a careful and accurate evaluation from an audiologist that you will have a reliable diagnosis. […] If you notice any of these symptoms in your child, CAPD is possible. Its a good idea to bring them to a trained professional to get a proper diagnosis and begin treatment so they can get back to learning in school. […] In regard to testing for CAPD: Your child must be older than age 6 — children younger than 6 dont have a fully mature auditory system and diagnosing CAPD might be difficult. […] Testing includes listening to speech that has been degraded in various ways, which is designed to tax the auditory system and determine if the brain is processing normally. […] The CCHAT Center performs CAPD evaluations for anyone who is interested.

    Auditory Processing Disorder is diagnosed by an audiologist. However, a team of both audiologists and speech language pathologists can make for a more accurate overall diagnosis. APD symptoms can often overlap with other disorders, such as language disorders. When a speech pathologist and an audiologist work together in the evaluation process, they can differentiate between language or phonological disorders from APD, properly identify APD and any co-occurring language disorders, and develop appropriate treatment plans. […] Assessment for APD includes a case history, an audiologic assessment, and an evaluation of the central auditory nervous system. A thorough case history includes prenatal and birth history, medical history, otologic history (including ear infections or surgeries), hearing status, cognitive skills, coexisting conditions, communication skills, and educational status. It is also important to conduct an audiologic assessment in order to determine if any hearing loss is present. In addition, the audiologist administers an auditory processing test. These may include auditory discrimination tests, auditory temporal processing and patterning tests, dichotic speech tests, monaural low-redundancy speech tests, and binaural interaction tests.

    Disorder is typically diagnosed when the individual has a deficit in two or more areas assessed during testing. […] Auditory Processing Disorder (APD) can be identified in elementary-aged children. […] APD is diagnosed by an audiologist, but is often assessed in a multidisciplinary approach between a team of professionals in order to fully understand the multitude of challenges exhibited by those with APD. […] Although an individual may exhibit many of the characteristics consistent with APD, diagnosis is only confirmed after careful testing and evaluation. […] Following testing, treatment and remediation are recommended based on the specific areas showing deficits in performance. […] Treatment for APD usually focuses on three primary areas: changing the communication environment, learning to use higher-order skills to help compensate for the deficits, and remediation of the auditory deficit itself.

[…] APD is diagnosed by an audiologist following administration of a test battery that assesses a variety of auditory processes. According to the American Academy of Audiology, a diagnosis of APD can be made when the individual scores two standard deviations or more below the mean in at least one ear on two or more tests within the battery. […] Intervention options for APD should be individualized and specific to the patients case history and test results. A multi-disciplinary team management approach is often used, and may include speech-language pathologists, teachers, parents, etc. Recommendations made on a case-specific basis may include direct skills training, compensatory strategies, and environmental modifications, just to name a few.

    A recent submission to Ear and Hearing on early diagnosis of APD ended up on my desk after three expert reviewers and another member of our Editorial Board provided a highly detailed critique of the paper. What most caught my attention was that 2 of 3 reviewers questioned the premise of whether an earlier diagnosis of APD will ultimately prove useful since the status of APD is so controversial or difficult to verify. […] Numerous international audiology societies have published their own guidelines on APD, but I would like to cite one part of the British Society of Audiology guidelines that may help define and limit what it is I object to. The BSA proposed three types of APD: Secondary APD, Acquired APD and Developmental APD. […] However, the notion that children with listening difficulties have a disorder of central auditory function that may be diagnosed with some arbitrary combination of the commonly used clinical tests for APD is unjustified in the view of many scientists and clinicians, including the Editorial Board of this Journal. Such a diagnosis could even be harmful if it prevents children receiving evidence-based and soundly reasoned diagnosis and treatment.

    Auditory processing disorder (APD) is a neurodevelopmental disorder affecting the way the brain processes sounds. Individuals with APD usually have normal structure and function of the ear, but cannot process the information they hear in the same way as others do, which leads to difficulties in recognizing and interpreting sounds, especially the sounds composing speech. It is thought that these difficulties arise from dysfunction in the central nervous system. […] The American Academy of Audiology notes that APD is diagnosed by difficulties in one or more auditory processes known to reflect the function of the central auditory nervous system. […] According to the New Zealand Guidelines on Auditory Processing Disorders (2017), the following checklist of key symptoms of APD or comorbidities can be used to identify individuals who should be referred for audiological and APD assessment: Difficulty following spoken directions unless they are brief and simple, Difficulty attending to and remembering spoken information, Slowness in processing spoken information, Difficulty understanding in the presence of other sounds, Overwhelmed by complex or „busy” auditory environments e.g. classrooms, shopping malls, Poor listening skills, Insensitivity to tone of voice or other nuances of speech, Acquired brain injury, History of frequent or persistent middle ear disease (otitis media, „glue ear”).

    Auditory processing disorder (APD) is a neurodevelopmental disorder affecting the way the brain processes sounds. Individuals with APD usually have normal structure and function of the ear, but cannot process the information they hear in the same way as others do, which leads to difficulties in recognizing and interpreting sounds, especially the sounds composing speech. It is thought that these difficulties arise from dysfunction in the central nervous system. […] The American Academy of Audiology notes that APD is diagnosed by difficulties in one or more auditory processes known to reflect the function of the central auditory nervous system. […] According to the New Zealand Guidelines on Auditory Processing Disorders (2017), the following checklist of key symptoms of APD or comorbidities can be used to identify individuals who should be referred for audiological and APD assessment: Difficulty following spoken directions unless they are brief and simple, Difficulty attending to and remembering spoken information, Slowness in processing spoken information, Difficulty understanding in the presence of other sounds, Overwhelmed by complex or „busy” auditory environments e.g. classrooms, shopping malls, Poor listening skills, Insensitivity to tone of voice or other nuances of speech, Acquired brain injury, History of frequent or persistent middle ear disease (otitis media, „glue ear”).

    Testing for Auditory Processing Disorder (APD) refers to evaluation of the central auditory system. Several tests of central auditory function comprise an auditory processing test battery. These separate tests may include but are not limited to evaluation of different auditory processing functions, such as auditory temporal processing, auditory pattern processing, binaural separation, binaural integration and auditory performance with degraded acoustic signals. […] The ICD code H93.25 Central auditory processing disorder is most appropriate for reporting a diagnosis of auditory processing disorder. […] The tests used in an APD evaluation may vary based on patients presenting symptoms. It is for this reason that the APD evaluation codes (92620 and 92621) are timed codes which allow audiologists the flexibility to utilize the most appropriate measures for each individual situation.

    Auditory Processing Disorder is diagnosed by an audiologist. However, a team of both audiologists and speech language pathologists can make for a more accurate overall diagnosis. APD symptoms can often overlap with other disorders, such as language disorders. When a speech pathologist and an audiologist work together in the evaluation process, they can differentiate between language or phonological disorders from APD, properly identify APD and any co-occurring language disorders, and develop appropriate treatment plans. […] Assessment for APD includes a case history, an audiologic assessment, and an evaluation of the central auditory nervous system. A thorough case history includes prenatal and birth history, medical history, otologic history (including ear infections or surgeries), hearing status, cognitive skills, coexisting conditions, communication skills, and educational status. It is also important to conduct an audiologic assessment in order to determine if any hearing loss is present. In addition, the audiologist administers an auditory processing test. These may include auditory discrimination tests, auditory temporal processing and patterning tests, dichotic speech tests, monaural low-redundancy speech tests, and binaural interaction tests.
  • #13 What Is Auditory Processing Disorder (APD) And How to Treat It
    https://www.soundly.com/blog/auditory-processing-disorder
    Do you hear well but have trouble making sense of speech? You may have Auditory Processing Disorder. Also known as APD, this disorder affects how your brain processes the sounds it receives. […] Diagnosing APD involves ruling out other etiologies that can interfere with focus, concentration, or attention. […] Audiologists who specialize in APD testing play a key role in the diagnosis, once other possibilities have been ruled out. […] It is critical to highlight that people with APD can understand complex concepts when they receive them in other ways, such as through reading or if a speaker talks slowly and there is no background noise. […] An audiologist will conduct a series of tests to determine whether an APD diagnosis is appropriate. […] Its important to note that APD is a diagnosis of exclusion.

    https://oatext.com/Auditory-Processing-Disorder-APD-Be-vigilant-and-aware.php
    Auditory Processing Disorder (APD) are defects of the auditory sense, which result from abnormalities in the functioning of the auditory path at the level of the central nervous system from the center of the Cochlea to the auditory cortex. This is a problem that 2-3% of children, aged 7-14 suffer from in Poland. […] The aim of this paper is to establish a spectrum of the most common symptoms as well as to determine the most common age range of the children that have been diagnosed. […] The most common symptoms among patients who have been diagnosed with APD were as follows: late speech development (96%), speech defects (91.4%), problems with learning a language (91.67%). […] The accuracy of the initial diagnosis was the highest in the 6 to 7 age group (96.15%). […] The aim of this paper is to establish a spectrum of the most common symptoms as well as to determine the most common age range of the children that have been diagnosed with auditory processing disorder.

    To diagnose auditory processing disorder (APD), your health care team may ask questions about your symptoms and how long you have had them, as well as order tests. […] Several specialists on your health care team might help diagnose you or your child with auditory processing disorder (APD). […] A hearing specialist called an audiologist may do tests to see what is happening when you or your child hear sounds. […] The computer records how the nerves between the ears and the brain respond to the sounds. […] This test shows how well sound travels along the nerves that connect the ears to the brain. […] For auditory processing disorder, some basic questions to ask include: What tests are needed? […] Your health care team is likely to ask you questions, such as: What, if anything, helps you hear better?

    The introduction of tests for these disorders was preceded by complete electrophysiological test as well as imaging tests of the auditory pathway. […] Even though one abnormal result from among the tests described in the methodology is enough to recognize APD, both its sensitivity and specificity is low. […] The results of this paper speak for the necessity of increasing APD awareness among people close to a child as the problems that emerge are common and a lot of the diagnoses late. […] The confirmation of the initial diagnosis was established if the results of at least three of the following tests were not correct. […] The most common issue among patients diagnosed with APD is a delayed development of speech during childhood, problems at school (mainly in learning languages and math), speech impediments and delayed.

    Auditory processing disorder (APD), sometimes referred to as central auditory processing disorder (CAPD), is a general term for hearing disorders in which the ears process sound normally but the hearing centres and circuits of the brain dont always process incoming information sufficiently quickly or accurately. […] APD can also arise in adulthood as a consequence of disease, injury or ageing. APD is a common consequence of brain injury and stroke. […] Adults with APD often report that they can hear but they sometimes have trouble understanding what they hear. […] APD can especially affect understanding in challenging listening situations such as in the presence of other distracting sound or when listening to complex information. […] Sometimes adults who receive an APD diagnosis conclude that APD may explain past difficulty at school with academic progress, social and behavioural difficulties.

    These, and other common signs of APD, are not unique to APD and should not be treated as definitive signs that an APD is present. It is also important to note that in children, APD may coexist with other disorders, including language, reading, learning, or attention deficit. […] There is no uniform criteria for the assessment and diagnosis of APD and therefore estimates to the prevalence of APD are variable. Common estimates regarding the prevalence of APD in the pediatric population are low (2-3%), with a higher estimated prevalence in older adults. […] Age is a primary consideration for the evaluation of APD in children. Individuals 7 years of age or older can be tested for APD. This is due to age-related variability in brain function, language proficiency, and cognitive status. […] A comprehensive audiologic evaluation (CAE) is recommended for all individuals suspected of having APD, as even a mild hearing loss can cause difficulties similar to those commonly associated with APD.
