Zaburzenie osobowości schizotypowe – Diagnostyka i diagnoza

Zaburzenie osobowości schizotypowe
Diagnostyka i diagnoza

Schizotypowe zaburzenie osobowości (STPD) charakteryzuje się utrwalonym wzorcem deficytów społecznych i interpersonalnych, w tym ostrym dyskomfortem w bliskich relacjach, zniekształceniami poznawczymi lub percepcyjnymi oraz ekscentrycznym zachowaniem. Diagnoza według DSM-5-TR wymaga obecności co najmniej 5 z 9 specyficznych objawów, takich jak idee odnoszące, myślenie magiczne, niezwykłe doświadczenia percepcyjne, dziwaczna mowa, podejrzliwość, ograniczony afekt, ekscentryczne zachowanie, brak bliskich przyjaciół oraz nadmierny lęk społeczny. Zaburzenie musi być wykluczone jako objaw schizofrenii, zaburzeń afektywnych z cechami psychotycznymi czy spektrum autyzmu. Alternatywny model DSM-5-TR wymaga obecności co najmniej 4 cech z zakresu zaburzeń funkcjonowania osobowości, interpersonalnego, psychotyczności, ekscentryczności, odłączenia i negatywnego afektu. ICD-11 klasyfikuje STPD jako formę schizofrenii, co odzwierciedla trwającą debatę na temat jego natury.

Schizotypal Personality Disorder – Kryteria Diagnostyczne

Schizotypal personality disorder (STPD) to zaburzenie osobowości charakteryzujące się utrwalonym wzorcem trudności społecznych i interpersonalnych, którego przejawem jest ostry dyskomfort w bliskich relacjach oraz zmniejszona zdolność do ich tworzenia, jak również zaburzenia poznawcze lub percepcyjne oraz ekscentryczne zachowania. Rozpoznanie tego zaburzenia opiera się na specyficznych kryteriach diagnostycznych, które muszą być spełnione do postawienia diagnozy.¹²

Kryteria diagnostyczne według DSM-5-TR

Zgodnie z Diagnostic and Statistical Manual of Mental Disorders, 5th Edition, Text Revision (DSM-5-TR), diagnoza zaburzenia osobowości schizotypowej wymaga obecności utrwalonego wzorca deficytów społecznych i interpersonalnych, charakteryzującego się ostrym dyskomfortem w bliskich relacjach oraz zmniejszoną zdolnością do ich tworzenia, a także zniekształceniami poznawczymi lub percepcyjnymi i ekscentrycznością zachowania. Objawy te zazwyczaj pojawiają się we wczesnej dorosłości i występują w różnych kontekstach.¹²

Do postawienia diagnozy konieczne jest stwierdzenie przynajmniej pięciu z dziewięciu następujących objawów:¹²

Idee odnoszące (z wyłączeniem urojeń odnoszących) – przekonanie, że codzienne zdarzenia mają szczególne znaczenie skierowane specjalnie do danej osoby¹²
Dziwaczne przekonania lub myślenie magiczne, które wpływa na zachowanie i jest niezgodne z normami subkulturowymi (np. przesądność, wiara w jasnowidzenie, telepatię lub „szósty zmysł”)¹²
Niezwykłe doświadczenia percepcyjne, w tym złudzenia cielesne¹²
Dziwaczne myślenie i mowa (np. nieokreślona, okoliczna, metaforyczna, przesadnie zawiła lub stereotypowa)¹²
Podejrzliwość lub myślenie paranoidalne¹²
Nieadekwatny lub ograniczony afekt¹²
Zachowanie lub wygląd dziwaczny, ekscentryczny lub osobliwy¹²
Brak bliskich przyjaciół lub powierników poza krewnymi pierwszego stopnia¹²
Nadmierna lęk społeczny, który nie zmniejsza się wraz z poznawaniem danego środowiska i ma tendencję do wiązania się z lękami paranoidalnymi, a nie negatywnymi osądami o sobie¹²

Ponadto, zgodnie z kryterium B, zaburzenie nie może występować wyłącznie podczas przebiegu schizofrenii, zaburzenia afektywnego dwubiegunowego lub depresyjnego z cechami psychotycznymi, innego zaburzenia psychotycznego lub zaburzenia ze spektrum autyzmu.¹²

Alternatywny model diagnostyczny

DSM-5-TR wprowadził alternatywny model diagnostyczny dla zaburzeń osobowości w sekcji „Emerging Measures and Models”. W tym modelu, diagnoza zaburzenia osobowości schizotypowej opiera się na następujących kategoriach objawów:¹²

Ogólne zaburzenia funkcjonowania osobowości i poczucia własnego „ja” (tożsamość i samoukierunkowanie)
Zaburzenia funkcjonowania interpersonalnego (empatia, intymność)
Specyficzne dla STPD patologiczne cechy osobowości, określane jako psychotyczność, ekscentryczność, dysregulacja poznawcza i percepcyjna oraz nietypowe przekonania i doświadczenia
Odłączenie charakteryzujące się ograniczonym afektem i wycofaniem
Negatywny afekt charakteryzujący się podejrzliwością

Diagnoza w tym modelu wymaga obecności co najmniej czterech z powyższych cech.¹²

Różnice w klasyfikacjach

Warto zauważyć, że podczas gdy DSM-5-TR nadal klasyfikuje schizotypowe zaburzenie osobowości jako zaburzenie osobowości, Światowa Organizacja Zdrowia w Międzynarodowej Klasyfikacji Chorób, wydanie 11 (ICD-11), przeklasyfikowała je jako formę schizofrenii. Ta rozbieżność odzwierciedla trwającą debatę na temat natury tego zaburzenia.¹²

W DSM-5, zaburzenie to jest wymienione zarówno jako zaburzenie osobowości, jak i jako zaburzenie ze spektrum schizofrenii. Jest to spowodowane tym, że niektórzy eksperci medyczni uważają schizotypowe zaburzenie osobowości za wczesny objaw schizofrenii.¹²

Proces diagnostyczny

Prawidłowa diagnoza zaburzenia osobowości schizotypowego wymaga dokładnej i kompleksowej oceny przeprowadzonej przez wykwalifikowanego specjalistę w dziedzinie zdrowia psychicznego, takiego jak psychiatra lub psycholog.¹²

Wywiad kliniczny

Diagnoza opiera się przede wszystkim na dokładnym wywiadzie klinicznym, podczas którego specjalista zbiera informacje na temat objawów, historii osobistej i medycznej pacjenta, w tym wcześniejszych terapii.¹²

Podczas wywiadu klinicznego specjalista może koncentrować się na następujących obszarach:¹

Historia dzieciństwa
Relacje interpersonalne
Historia zawodowa
Testowanie rzeczywistości (zdolność do odróżniania rzeczywistości od fantazji)

Ponieważ osoby z zaburzeniem osobowości schizotypowym mogą nie być świadome problematycznych aspektów swojego zachowania lub sposobu myślenia, specjaliści często współpracują z rodziną i przyjaciółmi pacjenta, aby zebrać dodatkowe informacje o jego zachowaniu i historii.¹

Badanie fizykalne

Przed postawieniem diagnozy, lekarz przeprowadza badanie fizykalne, aby wykluczyć inne schorzenia medyczne, które mogłyby powodować podobne objawy.¹²

Nie istnieją specyficzne testy laboratoryjne, które mogłyby jednoznacznie określić, czy dana osoba ma zaburzenie osobowości schizotypowe. Diagnoza opiera się na objawach klinicznych i wywiadzie.¹²

Narzędzia diagnostyczne

Do diagnozowania zaburzenia osobowości schizotypowego mogą być stosowane różne narzędzia psychometryczne, które pomagają w ocenie objawów i postawieniu diagnozy:¹²

Schizotypal Personality Questionnaire-Brief (SPQ-Brief) – skrócona wersja kwestionariusza do badania cech schizotypowych
Personality Diagnostic Questionnaire-4 (PDQ-4+) – kwestionariusz diagnostyczny do badania zaburzeń osobowości, bardziej odpowiedni do wstępnej selekcji
Personality Inventory for DSM-5 (PID-5) – inwentarz osobowości zgodny z kryteriami DSM-5
Minnesota Multiphasic Personality Inventory (MMPI) – wielowymiarowy kwestionariusz osobowości
Structured Interview for DSM (SIDP) i Structured Clinical Interview for DSM (SCID-II) – ustrukturyzowane wywiady kliniczne, które są odpowiednie do diagnozowania STPD

Badania potwierdzają, że SIDP dla DSM-III, SIDP-R dla DSM-III-R oraz SCID-II dla DSM-IV są odpowiednie do diagnozowania STPD, podczas gdy PDQ-4+ jest bardziej odpowiedni do wstępnej selekcji.¹²

Rozpoznanie różnicowe

Diagnostyka różnicowa zaburzenia osobowości schizotypowego jest szeroka. Objawy STPD muszą być odróżnione od:¹²

Zaburzeń neurorozwojowych, w tym zaburzeń ze spektrum autyzmu
Zmian osobowości spowodowanych innymi schorzeniami medycznymi
Zaburzeń związanych z używaniem substancji psychoaktywnych
Innych zaburzeń psychicznych z objawami psychotycznymi, takich jak schizofrenia, zaburzenia afektywne dwubiegunowe lub zaburzenia depresyjne z cechami psychotycznymi
Innych zaburzeń osobowości, szczególnie z klastra A (paranoidalne, schizoidalne)

Szczególnie ważne jest odróżnienie STPD od schizofrenii. Podstawowa różnica polega na tym, że osoby z STPD zazwyczaj mogą być świadome tego, jak ich zniekształcone idee różnią się od rzeczywistości, podczas gdy osoby ze schizofrenią mają trudności z interpretacją i zarządzaniem rzeczywistością. Ponadto, osoby z STPD nie doświadczają psychozy, halucynacji czy urojeń, które są charakterystyczne dla schizofrenii.¹²

Czynniki kulturowe

Podczas diagnozowania STPD należy uwzględnić czynniki kulturowe. Przekonania takie jak życie po śmierci, mówienie w językach, voodoo, szamanizm, czytanie w myślach, szósty zmysł, złe oko, magiczne przekonania związane ze zdrowiem i chorobą oraz inne kwestie związane z kulturą muszą być brane pod uwagę przy ocenie zniekształceń poznawczych i percepcyjnych.¹²

Wyzwania diagnostyczne

Diagnoza zaburzenia osobowości schizotypowego wiąże się z wieloma wyzwaniami, które mogą utrudniać prawidłowe rozpoznanie i leczenie.¹²

Trudności w diagnozowaniu

Zaburzenia osobowości, w tym STPD, są często niedodiagnozowane, ponieważ lekarze czasami koncentrują się na objawach lęku lub depresji, które są znacznie częstsze w ogólnej populacji niż zaburzenia osobowości.¹

Postawienie diagnozy STPD może wymagać wielu spotkań, zanim zostanie ostatecznie ustalona. Jest to spowodowane złożonością objawów i potrzebą wykluczenia innych zaburzeń.¹

Dodatkowo, osoby z STPD mogą szukać pomocy u specjalisty z powodu innych objawów, takich jak lęk, depresja lub problemy z radzeniem sobie w sytuacjach społecznych, a także w celu leczenia nadużywania substancji, a nie z powodu samego zaburzenia osobowości.¹

Wiek diagnozy

STPD zazwyczaj diagnozuje się we wczesnej dorosłości, chociaż niektóre cechy tego stanu mogą pojawić się już w dzieciństwie i okresie dojrzewania. Objawy, takie jak większe zainteresowanie aktywnościami wykonywanymi samodzielnie lub wysoki poziom lęku społecznego, mogą być widoczne już w okresie dojrzewania.¹²

Podobnie jak w przypadku innych zaburzeń osobowości, osoba z STPD zazwyczaj jest nastolatkiem lub dorosłym, zanim można ocenić, czy spełnia pełne kryteria objawowe dla diagnozy tej choroby.¹

Współwystępowanie innych zaburzeń

STPD może współwystępować z innymi zaburzeniami, w tym z zaburzeniem osobowości z pogranicza (borderline), ADHD, zaburzeniem lękowym społecznym i zaburzeniem ze spektrum autyzmu, co może dodatkowo komplikować diagnozę.¹

Zaburzenie osobowości schizotypowej rzadko jest widziane jako główny powód leczenia w warunkach klinicznych, ale często występuje jako współistniejące zaburzenie z innymi zaburzeniami psychicznymi.¹

Znaczenie prawidłowej diagnozy

Prawidłowa diagnoza STPD jest kluczowa dla określenia odpowiednich opcji leczenia i poprawy rokowania.¹²

Konsekwencje nieleczonego zaburzenia

Nieleczone STPD może prowadzić do wielu potencjalnych powikłań, w tym zwiększonego ryzyka używania substancji psychoaktywnych, samookaleczenia i hospitalizacji.¹

Jeśli nie jest leczone, rokowanie dla zaburzenia osobowości schizotypowego jest na ogół złe. Zaburzenie to upośledza zdolność osoby do interpretowania wskazówek społecznych i może znacząco wpływać na jakość życia.¹²

Możliwość progresji do schizofrenii

Zaburzenie osobowości schizotypowej nie zawsze prowadzi do schizofrenii. Niektórzy badacze szacują, że od 24% do 40% osób z tym zaburzeniem może ostatecznie otrzymać diagnozę schizofrenii.¹

Podobieństwa między STPD a schizofrenią są powodem, dla którego DSM-5 uważa STPD za zaburzenie ze spektrum schizofrenii. Oznacza to, że STPD może być w niektórych przypadkach postrzegane jako mniej poważna odmiana schizofrenii.¹

Jednak istnieje różnica między tymi dwoma stanami, która często znajduje się w intensywności, czasie trwania i częstotliwości objawów.¹

Odpowiednie leczenie

Skuteczne leczenie STPD opiera się na nawiązaniu i utrzymaniu kontaktu terapeutycznego. Wykazano, że rysperydon, a w ograniczonym zakresie olanzapina, mają najlepsze dowody na skuteczność w STPD.¹²

Literatura na temat psychoterapii jest ograniczona i nie pozwala na sformułowanie konkretnych zaleceń, choć trening umiejętności społecznych wydaje się być skuteczny i powinien być oferowany pacjentom z STPD.¹²

Dla osób z STPD zaleca się leczenie pierwszego rzutu w postaci długoterminowej, psychodynamicznie zorientowanej psychoterapii. Leczenie farmakologiczne jest preferowane w celu ukierunkowanego łagodzenia objawów w kontekście psychoterapii.¹

Epidemiologia STPD

Szacowana częstość występowania zaburzenia osobowości schizotypowego wynosi od 1% do 4%, chociaż te liczby mogą być zniekształcone przez nakładanie się objawów i możliwe błędne diagnozy innych zaburzeń psychicznych z objawami psychotycznymi.¹²

Zaburzenie osobowości schizotypowe ma tendencję do występowania u prawie 4% dorosłych, częściej u mężczyzn niż u kobiet.¹²

Osoby z STPD są bardziej narażone na ryzyko, jeśli członek rodziny cierpi na schizofrenię lub inne zaburzenie psychotyczne.¹²

Podsumowanie

Diagnoza zaburzenia osobowości schizotypowego wymaga dokładnej oceny klinicznej przeprowadzonej przez wykwalifikowanego specjalistę zdrowia psychicznego. Diagnoza opiera się na spełnieniu co najmniej pięciu z dziewięciu kryteriów diagnostycznych określonych w DSM-5-TR, a także na wykluczeniu innych zaburzeń, które mogą powodować podobne objawy.¹²

Zaburzenie to często współwystępuje z innymi zaburzeniami psychicznymi i może prowadzić do znacznego upośledzenia funkcjonowania społecznego i zawodowego. Wczesna diagnoza i odpowiednie leczenie są kluczowe dla poprawy rokowania i jakości życia osób z STPD.¹²

Pomimo wyzwań diagnostycznych, dostępne są rzetelne narzędzia do badania przesiewowego i diagnozowania STPD. Jednak ze względu na heterogeniczność badań i małe próby, nadal nie jest możliwe sformułowanie zaleceń opartych na dowodach dotyczących leczenia.¹²

Despite these research efforts, evidence-based recommendations are still lacking for the diagnosis and treatment of STPD. […] Our evaluation of diagnostic instruments made clear that the diagnosis of STPD has changed over time. […] Nearly all the diagnostic instruments discussed for STPD have adequate inter-rater and testretest reliability. […] Our review confirms that the SIDP for DSM-III, SIDP-R for DSM-III-R, and SCID-II for DSM-IV are suitable for diagnosing STPD, but we found that the diagnostic tool PDQ-4+ is more suitable for screening. […] The articles on treatment clearly showed that antipsychotics are the most frequently used drugs. […] When we considered only studies that were of acceptable methodological quality, risperidone had the best, but still limited, evidence for reducing clinical symptoms in patients with STPD. […] The literature on psychotherapy is sparse and does not allow us to make any recommendations, although social skills training seems to be effective and should be offered to patients with STPD.
