Prosopagnozja (ślepota twarzy)
Objawy

Prosopagnozja, czyli ślepota twarzy, to zaburzenie neurologiczne charakteryzujące się niezdolnością do rozpoznawania twarzy, mimo zachowanego prawidłowego przetwarzania innych bodźców wzrokowych i funkcji intelektualnych. Etiologia obejmuje uszkodzenie lub dysfunkcję zakrętu wrzecionowatego w prawej półkuli mózgu, kluczowego dla percepcji i pamięci twarzy. Występuje w formie rozwojowej (wrodzonej) oraz nabytej, często po udarze, urazie głowy czy chorobach neurodegeneracyjnych. Objawy obejmują trudności w rozpoznawaniu twarzy bliskich, własnej twarzy, a także problem z interpretacją emocji i cech demograficznych. Nasilenie objawów waha się od łagodnej (problemy z rozpoznawaniem nieznajomych) do skrajnej (niemożność odróżnienia twarzy od obiektów). Prosopagnozja współwystępuje z innymi zaburzeniami neurologicznymi, m.in. autyzmem (ok. 40% przypadków), achromatopsją mózgową, agnozją obiektów czy ADHD.

Prosopagnozja (ślepota twarzy) – definicja i charakterystyka

Prosopagnozja, zwana również ślepotą twarzy, jest zaburzeniem neurologicznym charakteryzującym się niezdolnością do rozpoznawania twarzy. Osoba z prosopagnozją widzi części twarzy normalnie, jednak wszystkie twarze mogą wyglądać dla niej tak samo. Jest to zaburzenie specyficzne, które wpływa na percepcję twarzy, podczas gdy inne aspekty przetwarzania wzrokowego (np. rozpoznawanie obiektów) oraz funkcjonowanie intelektualne (np. podejmowanie decyzji) pozostają nienaruszone.12

Prosopagnozja jest spowodowana problemem w części mózgu odpowiedzialnej za przetwarzanie informacji o twarzach. Obszarem mózgu najczęściej związanym z prosopagnozją jest zakręt wrzecionowaty, który aktywuje się specyficznie w odpowiedzi na twarze.34 Badania sugerują, że około 2-3% populacji ogólnej może mieć prosopagnozję, choć nowsze badania wskazują, że może to dotyczyć nawet 3,08% (jedna na 33 osoby).56

Rodzaje prosopagnozji

Prosopagnozja występuje w dwóch głównych formach:78

Dodatkowo, można wyróżnić dwa warianty prosopagnozji:1314

  • Apperceptywna prosopagnozja – osoba nie jest w stanie nawet prawidłowo postrzegać i przetwarzać poznawczo twarzy, widzi niewyraźny obraz zamiast charakterystyk twarzy.
  • Asocjacyjna/amnestyczna prosopagnozja – osoba może identyfikować cechy twarzy, ale nie może kojarzyć ich z konkretnymi osobami, które zna; informacje percepcyjne nie mogą uzyskać dostępu do wspomnień twarzy z powodu rozłączenia lub ich utraty.

Objawy prosopagnozji

Głównym objawem prosopagnozji jest trudność w rozpoznawaniu twarzy. Nasilenie tego objawu może się jednak różnić w zależności od osoby.1516

Trudności w rozpoznawaniu twarzy

Osoby z prosopagnozją doświadczają następujących trudności:171819

  • Trudności w rozpoznawaniu znajomych twarzy, w tym rodziny i przyjaciół
  • Problemy z rozpoznawaniem własnej twarzy w lustrze lub na zdjęciach
  • Niemożność odróżnienia twarzy nieznajomych
  • Trudności w rozpoznawaniu osób, które widzieli wielokrotnie
  • Poleganie na innych wskazówkach niż twarz (fryzura, ubiór, głos) w celu identyfikacji osoby
  • Problemy z rozpoznawaniem osób po zmianie ich wyglądu (np. po zmianie fryzury)

Dodatkowe objawy

Oprócz trudności w rozpoznawaniu twarzy, osoby z prosopagnozją mogą doświadczać również:202122

  • Trudności w interpretowaniu wyrazów twarzy i emocji
  • Problemy z rozpoznawaniem wieku i płci osoby na podstawie twarzy
  • Trudności w śledzeniu wzroku innych osób
  • Problemy z rozpoznawaniem postaci i śledzeniem fabuły w programach telewizyjnych lub filmach
  • Trudności w rozpoznawaniu innych rzeczy, takich jak samochody, zwierzęta czy miejsca
  • Problemy z orientacją przestrzenną i znajdowaniem drogi
  • Trudności w opisywaniu twarzy znanych osób

Ciężkość objawów

Nasilenie objawów prosopagnozji może się znacznie różnić między osobami:232425

  • Łagodna prosopagnozja – trudności w rozpoznawaniu nieznajomych lub mało znanych osób
  • Umiarkowana prosopagnozja – trudności w rozpoznawaniu dobrze znanych osób, w tym przyjaciół i rodziny
  • Ciężka prosopagnozja – niemożność rozpoznania nawet najbliższych osób, w tym współmałżonka i dzieci, a także własnej twarzy
  • Skrajna prosopagnozja – niemożność odróżnienia twarzy od obiektu

W przypadku prosopagnozji wrodzonej, osoby często nie zdają sobie sprawy ze swojego deficytu, ponieważ nigdy nie doświadczyły normalnego rozpoznawania twarzy.2627

Prosopagnozja u dzieci

Rozpoznawanie twarzy jest umiejętnością, która rozwija się przez całe dzieciństwo, osiągając pełną dojrzałość w połowie okresu dojrzewania. Prosopagnozja u dzieci może przejawiać się w następujący sposób:2829

  • Nierozpoznawanie znajomych osób
  • Trudności w nawiązywaniu przyjaźni i wycofanie społeczne
  • Omyłkowe podchodzenie do nieznajomych
  • Czekanie na machnięcie ręką przed podejściem do rodzica przy bramie szkolnej
  • Trudności w śledzeniu programów telewizyjnych (preferowanie postaci z kreskówek)
  • Rozproszenie uwagi (szukanie wskazówek dotyczących tożsamości osoby po jej butach, torbie itp.)
  • Nierozpoznawanie kogoś po zmianie wyglądu (np. fryzury)
  • Nadmierna „przylepność” w tłumie

Dzieci z prosopagnozją mogą mieć dodatkowe wyzwania, takie jak:30

  • Brak strachu przed nieznajomymi, ponieważ nie rozróżniają znajomych od nieznajomych twarzy, co może prowadzić do potencjalnie niebezpiecznych sytuacji
  • Intensywny strach przed zgubieniem się lub odłączeniem od rodziców i nauczycieli, ponieważ wiedzą, że mieliby trudności z ich rozpoznaniem i odnalezieniem
  • Różne zachowanie w szkole i w domu, ponieważ mogą czuć się bardziej komfortowo z członkami rodziny, których łatwiej rozpoznają na podstawie innych wskazówek niż twarz (np. fryzura)

Prosopagnozja a choroby współistniejące

Prosopagnozja może współwystępować z innymi zaburzeniami neurologicznymi i rozwojowymi:3132

Zaburzenia ze spektrum autyzmu

Prosopagnozja wydaje się być bardziej rozpowszechniona wśród osób z autyzmem niż w populacji ogólnej. Badania sugerują, że około 40% osób z autyzmem może mieć również objawy prosopagnozji.3334 U osób z autyzmem i prosopagnozją, ślepota twarzy jest bardziej związana z problemami z identyfikacją społeczną i komunikacją.35

Inne zaburzenia współistniejące

Prosopagnozja była również związana z innymi zaburzeniami, które są powiązane z sąsiednimi obszarami mózgu:3637

  • Lewostronna hemianopsja (częściowa ślepota)
  • Achromatopsja mózgowa (niezdolność do postrzegania kolorów)
  • Agnozja obiektów (niezdolność do rozpoznawania obiektów)
  • Topografagnozja (deficyty nawigacyjne)
  • Deficyty w interpretacji wyrazu twarzy
  • Zespół Turnera
  • Zespół Williamsa
  • ADHD (według niektórych badań osoby z ADHD mogą mieć większe prawdopodobieństwo doświadczania ślepoty twarzy)38

Wpływ prosopagnozji na życie codzienne

Prosopagnozja może mieć znaczący wpływ na codzienne życie osoby dotkniętej tym zaburzeniem:3940

Wpływ społeczny

Trudności w rozpoznawaniu twarzy mogą utrudniać tworzenie relacji i powodować problemy w pracy lub szkole.4142 Osoby z prosopagnozją mogą:

  • Unikać sytuacji społecznych z obawy przed zakłopotaniem lub frustracją związaną z nierozpoznawaniem twarzy
  • Być postrzeganymi jako aroganckie, niegrzeczne lub zdystansowane
  • Mieć trudności w nawiązywaniu i utrzymywaniu relacji
  • Doświadczać izolacji społecznej
  • Mieć trudności w sytuacjach zawodowych, które wymagają rozpoznawania twarzy

Wpływ na zdrowie psychiczne

Trudności związane z prosopagnozją mogą wpływać na zdrowie psychiczne, prowadząc do:434445

  • Fobii społecznej i lęku społecznego
  • Depresji
  • Obniżonej samooceny
  • Poczucia wyobcowania
  • Frustracji, wstydu, niepokoju lub złości związanej z zaburzeniem

Strategie radzenia sobie

Osoby z prosopagnozją często rozwijają strategie kompensacyjne, aby radzić sobie z trudnościami w rozpoznawaniu twarzy:4647

  • Poleganie na innych wskazówkach niż twarz, takich jak głos, fryzura, chód, ubiór lub charakterystyczne cechy
  • Zapominanie używania imion lub unikanie sytuacji, gdy trzeba kogoś przedstawić
  • Kojarzenie osób z konkretnymi kontekstami lub otoczeniem
  • Bycie bezpośrednim w kwestii swojego zaburzenia (np. „Czy spotkaliśmy się wcześniej? Mam ślepotę twarzy i nie rozpoznaję osób”)
  • Unikanie miejsc, gdzie mogą spotkać znane osoby

Diagnoza prosopagnozji

Diagnoza prosopagnozji może być złożona i obejmuje różne metody oceny zdolności rozpoznawania twarzy:4849

Testy diagnostyczne

Diagnostyka prosopagnozji obejmuje trzy główne rodzaje testów:5051

  • Testy percepcji – oceniające zdolność pacjenta do rozróżniania różnych bodźców wizualnych twarzy
  • Testy rozpoznawania – oceniające krótko- i długoterminowe wzorce rozpoznawania twarzy
  • Testy identyfikacji twarzy – obejmujące inne wskazówki słuchowe lub dotykowe (takie jak nazywanie) pomagające w identyfikacji bodźców twarzy

Konkretne testy używane w diagnostyce prosopagnozji to:5253

  • Indeks dwudziestopunktowy prosopagnozji (PI20) – kwestionariusz samooceny składający się z 20 pozycji oceniających obecność i nasilenie cech prosopagnozji
  • Benton Face Recognition Test (BFRT) – test, w którym osoba ma dopasować daną twarz do jednej z sześciu prezentowanych twarzy, które nie są odróżniane przez nic, takiego jak włosy czy nakrycia głowy
  • Cambridge Face Memory Test (CFMT) – test oceniający zdolność uczenia się i rozpoznawania nieznanych twarzy
  • Cambridge Face Memory Test for Children (CFMT-C) – wersja dla dzieci

Badania obrazowe

Zaawansowane obrazowanie jest narzędziem badawczym wykorzystującym właściwości takie jak grubość kory mózgowej, aktywacja funkcjonalna i łączność do badania sieci zaangażowanych w różne rodzaje prosopagnozji.54 Badania te obejmują:

Leczenie i strategie kompensacyjne

Obecnie nie ma lekarstwa na prosopagnozję, a leczenie koncentruje się na strategiach kompensacyjnych i technikach radzenia sobie z trudnościami w rozpoznawaniu twarzy.5556

Strategie kompensacyjne

Osoby z prosopagnozją mogą nauczyć się korzystać z innych wskazówek do identyfikacji osób:5758

  • Wykorzystywanie wskazówek pozatwarzowych, takich jak głos, fryzura, chód, ubiór, biżuteria, akcent lub charakterystyczne cechy
  • Kojarzenie osób z konkretnymi środowiskami lub kontekstami
  • Korzystanie z pomocy technologicznych zaprojektowanych do wspomagania rozpoznawania twarzy i pamięci
  • Otwarte informowanie o swoim zaburzeniu

Terapie rehabilitacyjne

Niektóre badania sugerują, że pewne techniki mogą pomóc osobom z prosopagnozją poprawić ich zdolność rozpoznawania twarzy:5960

  • Treningi percepcyjne mające na celu poprawę umiejętności dopasowywania wewnętrznych cech twarzy
  • Techniki poprawiające zdolność całościowego przetwarzania twarzy
  • Strategie kodowania twarzy mające na celu poprawę przypominania sobie twarzy
  • Treningi poznawcze pomagające w ćwiczeniu rozpoznawania twarzy

Skuteczność tych interwencji dla osób z prosopagnozją pozostaje ograniczona, a ich zastosowanie i skuteczność podlegają różnym ograniczeniom.61 Obiecujące programy rehabilitacyjne/treningowe mogą poprawić umiejętności rozpoznawania twarzy o około 35%.62

Leczenie chorób współistniejących

Leczenie zaburzeń współistniejących, takich jak lęk społeczny i depresja, może pomóc złagodzić niektóre trudności związane z prosopagnozją:6364

  • Terapia z wykwalifikowanym psychiatrą lub psychologiem
  • Leki przeciwdepresyjne lub przeciwlękowe w razie potrzeby
  • Wsparcie psychologiczne w budowaniu pewności siebie

Przypadki szczególne

Prosopagnozja przemijająca

W niektórych przypadkach prosopagnozja może być stanem przejściowym, który poprawia się lub ustępuje z czasem. Dotyczy to zwłaszcza prosopagnozji nabytej związanej z pewnymi niedegeneracyjnymi przyczynami.6566 Na przykład, prosopagnozja związana z migreną może być przejściowa i ustępować.67

Prosopagnozja a COVID-19

Niedawne badania sugerują, że ślepota twarzy może być rzadkim objawem długiego COVID-19. W badaniu przeprowadzonym przez Dartmouth College, osoba określana jako „Annie” doświadczyła trudności w rozpoznawaniu twarzy i problemów z nawigacją po przebyciu COVID-19.6869

Badacze przeprowadzili ankietę wśród 54 innych osób z długim COVID-19 i stwierdzili, że wiele z nich zgłaszało nowe problemy z rozpoznawaniem twarzy, a także trudności z nawigacją w otoczeniu, zapamiętywaniem numerów telefonów i śledzeniem postaci w programach telewizyjnych.7071

Prosopagnozja a noszenie masek

Pandemia COVID-19 i powszechne noszenie masek na twarz stworzyły wyzwania dla wszystkich w zakresie rozpoznawania twarzy. Badanie przeprowadzone przez York University w Toronto i Ben-Gurion University w Izraelu potwierdziło ilościowe i jakościowe zmiany w przetwarzaniu [wizualnym] maskowanych twarzy, które mogą mieć znaczący wpływ na codzienne funkcjonowanie. W pewnym sensie wszyscy doświadczają obecnie pewnego stopnia ślepoty twarzy.72

Aspekty neurobiologiczne

Prosopagnozja jest uważana za wynik nieprawidłowości, uszkodzenia lub upośledzenia zakrętu wrzecionowatego w prawej półkuli mózgu, który koordynuje układy nerwowe kontrolujące percepcję i pamięć twarzy.7374

Rozpoznawanie twarzy wymaga niezwykle złożonego układu neuronów w płatach skroniowym i potylicznym, które muszą współpracować. Uszkodzenie dowolnej części sieci neuronowej, która dekoduje cechy twarzy, może spowodować rozwój ślepoty twarzy.75

U osób z prosopagnozją obserwuje się zmniejszoną aktywność w regionach mózgu związanych z wiedzą niewizualną, a także zmniejszoną łączność między regionami wizualnymi i niewizualnymi.76

Prosopagnozja jest związana przede wszystkim z zaangażowaniem zakrętów wrzecionowatych, głównie w prawej półkuli mózgu. Prawa część płatów skroniowego i potylicznego oraz łączący je zakręt wrzecionowaty są kluczowymi obszarami.77

  • #1 Prosopagnosia (face blindness) – NHS
    https://www.nhs.uk/conditions/face-blindness/
    Prosopagnosia, also called face blindness, is a condition where you have difficulty recognising people’s faces. […] The main symptom of prosopagnosia is having difficulty recognising faces. You’ll still see the parts of a face normally, but all faces may look the same to you. […] It affects people differently. Some people may not be able to tell the difference between strangers or people they do not know well. Others may not recognise the faces of friends and family, or even their own face. […] Other symptoms of prosopagnosia can include difficulty with recognising emotions on people’s faces, recognising people’s age and gender, recognising characters and following plots in TV programmes or films, recognising other things, such as cars or animals, and finding your way around. […] Difficulty recognising faces may make it harder to form relationships, or cause problems at work or school.
  • #2 Prosopagnosia – Wikipedia
    https://en.wikipedia.org/wiki/Prosopagnosia
    Prosopagnosia, also known as face blindness, is a cognitive disorder of face perception in which the ability to recognize familiar faces, including one’s own face (self-recognition), is impaired, while other aspects of visual processing (e.g., object discrimination) and intellectual functioning (e.g., decision-making) remain intact. […] The brain area usually associated with prosopagnosia is the fusiform gyrus, which activates specifically in response to faces. […] Acquired prosopagnosia results from occipito-temporal lobe damage and is most often found in adults. […] In congenital prosopagnosia, the individual never adequately develops the ability to recognize faces. […] There are no widely accepted treatments. […] Prosopagnosia has also been associated with other disorders that are associated with nearby brain areas: left hemianopsia, achromatopsia, and topographical disorientation.

    This may affect your mental health and may lead to social anxiety or depression. […] Prosopagnosia is caused by a problem with the part of the brain that processes information about faces. […] It can happen if you do not develop the ability to recognise faces – this is the most common type and may run in families, from brain damage, such as following a stroke, head injury, inflammation of the brain (encephalitis), or Alzheimer’s disease, or if you’re autistic.

    Living with prosopagnosia, especially if you are born with it, makes you unconsciously compensate by using other aspects of a person to recognize them, like their voice, mannerisms, gait, and other unique characteristics. […] People with face blindness start observing other aspects of a person more closely and depend less on facial features for recognition. […] Children can have face blindness. Congenital prosopagnosia is more common than the acquired type, and there is often a family history. […] It was earlier believed that approximately 2-2.5% of the world population may have face blindness, but recent research suggests that 3.08% (one in 33 persons) may have it.
  • #6 Face Blindness May Affect More than 3% of People, Study Finds
    https://www.psychiatrist.com/news/face-blindness-may-affect-more-than-3-of-people-study-finds/
    Prosopagnosia affects about 10 million Americans and can be caused by brain injury or developmental abnormalities. […] Poor facial recall can limit employment opportunities and cause social distress, but cognitive training and coaching may help those with milder forms. […] The results showed that face blindness lies on a continuum. Of the 3,341 people tested, 31 (.9 percent) had major prosopagnosia, while 72 (2.2 percent) had a milder form. […] DeGutis said that the facial recall challenges can be caused by a brain injury to occipital or temporal regions, referred to as acquired prosopagnosia, or it can be the result of a lifelong condition related to genetic or developmental abnormalities, referred to as developmental prosopagnosia. […] Face blindness can be a socially debilitating disorder that can limit employment opportunities. For example, networking is extremely difficult for people with prosopagnosia and can cause social distress and embarrassment. […] Recent evidence suggests that people with milder forms of face blindness may benefit from treatments that include cognitive training to enhance perceptual abilities or coaching aimed directly at improving face associations.

    Some people are born without the ability to recognize faces, known as congenital or developmental prosopagnosia. Children with this type of face blindness may not realize their inability to recognize faces until they are much older. […] Congenital prosopagnosia is not caused by any structural differences in the brain or brain damage. Some researchers believe that congenital prosopagnosia may be inherited since the condition tends to run in families. […] Acquired prosopagnosia may occur after brain damage from a head injury, stroke, or neurodegenerative diseases. Individuals with this type of prosopagnosia were previously able to recognize faces. Research suggests they are unlikely to gain back this ability, though they may learn to compensate. […] The neurological basis for prosopagnosia is not well understood.
  • #8 Face Blindness in Children and Current Interventions
    https://www.mdpi.com/2076-328X/13/8/676
    Children with prosopagnosia, also known as face blindness, struggle to recognize the faces of acquaintances, which can have a negative impact on their social interactions and overall functioning. […] Prosopagnosia, also known as face blindness, is a condition in which individuals are unable to easily and accurately recognize others by their faces. […] Prosopagnosia can manifest in two primary forms: acquired prosopagnosia (AP) and developmental prosopagnosia (DP). […] DP is more prevalent in the general population, affecting approximately 2–2.5% of adults and 1.2–4% of children. […] Prosopagnosia can have lasting effects on children’s ability to form and maintain social relationships. […] Nearly all individuals with prosopagnosia had trouble recognizing people they knew well, such as friends, co-workers, and family members.

    It is a neurological disorder that causes a person to not recognize or distinguish faces. This condition is not related to memory loss, vision impairment, or learning disabilities. With a prevalence of 2.5%, prosopagnosia can happen in two different ways, either as an acquired condition or as a congenital problem. Acquired prosopagnosia results from a stroke in the brain, a traumatic brain injury, Alzheimer’s, dementia, or another neurodegenerative disease. Congenital prosopagnosia refers to a disorder where a child is born with it due to the inheritance of some genes or the occurrence of a genetic mutation. Sometimes, this disorder appears in people with Autism Spectrum Disorder (ASD), Asperger Syndrome (AS), or Turner Syndrome (TS); this could be the cause of the social interaction challenges they face.

    Prosopagnosia is the inability of the brain to process the visual information about facial features that the eyes send to the brain. There can also be an inability to retain or recall the memory of information associated with a face. […] Prosopagnosia can occur following a stroke, trauma to the brain, or neurodegenerative diseases. […] Currently, there is no cure for face blindness. Treatment of prosopagnosia is mainly supportive and involves developing coping mechanisms to help manage the condition better.

  • #13 Prosopagnosia – StatPearls – NCBI Bookshelf
    https://www.ncbi.nlm.nih.gov/books/NBK559324/
    Prosopagnosia is defined as the inability to recognize known and new faces. It is also known as facial/visual agnosia. There are varying degrees of impairment in prosopagnosia, including: The inability to recognize, Discriminate, Identify different or own faces, Discern differences between faces and surrounding objects. This impairment causes a psychological and social impact leading to functional impairment, unemployment, social isolation, depression, anxiety, and other mood disorders. Prosopagnosia can be acquired or hereditary. Acquired cases can result from ischemic or hemorrhagic stroke, traumatic brain injury, certain neurodegenerative and neuropsychiatric illnesses (Alzheimer disease, depression, and schizophrenia). The prevalence can approach 2.5% of the population. Patients with juvenile prosopagnosia cannot recognize faces throughout their life, and a strong family history is usually present. Variants of prosopagnosia include an apperceptive variant (deficits in facial structure perception), and amnestic or associative variant (unable to remember faces even though they can perceive them; the perceptual information cannot access facial memories because of a disconnection or loss of them). The pathophysiology is still not completely understood and is a prominent area of research. Diagnostic tests can divide into three main types. First, perception tests that can accurately evaluate the patient’s ability to discriminate between different visual facial stimuli. Second, recognition tests that can specifically assess short and long term recognition patterns of faces. Third, facial identification tests that involve other auditory or tactile cues (such as naming) to help identify facial stimuli. Advanced imaging is a research tool that uses properties such as cortical thickness, functional activation, and connectivity to study the networks involved in different types of prosopagnosia. At this time, there is no evidence-based study that guides the creation of an interdisciplinary team for prosopagnosia.
  • #14 Prosopagnosia – EyeWiki
    https://eyewiki.org/Prosopagnosia
    Prosopagnosia, also known as face blindness, refers to the neuro-ophthalmic disorder in which a patient has difficulty perceiving or recognizing faces. […] Apperceptive prosopagnosia is defined as the inability to even perceive and cognitively process the face. Associative prosopagnosia is defined as inability to recognize or apply any meaning to the face, despite perceiving it. […] The diagnosis of prosopagnosia is made clinically. […] A patient with apperceptive prosopagnosia will claim they are unable to even perceive a face at all, let alone recognize who the face belongs to. […] A patient with associate prosopagnosia will claim no issue perceiving a face but will not be able to attach meaning to the face. […] Currently there are no effective treatments for prosopagnosia. […] Spontaneous recovery of prosopagnosia has been rarely noted in the literature.
  • #15 Prosopagnosia: Causes and managementMedical News Today
    https://www.medicalnewstoday.com/articles/prosopagnosia
    Prosopagnosia is a neurological condition where a person is unable to recognize faces. It typically arises due to problems or damage in specific areas of the brain that process facial information. […] Also known as face blindness or facial agnosia, this condition results in the inability to recognize faces. […] The primary symptom of prosopagnosia is an inability to recognize faces. However, the severity of this symptom can vary among those living with face blindness. […] Symptoms may also depend on the type of prosopagnosia. For example, a type of prosopagnosia known as apperceptive prosopagnosia describes when a person sees a blurry image instead of a person’s facial characteristics. Associative prosopagnosia refers to when a person can identify facial features but cannot associate the faces with individuals they know.
  • #16 Face Blindness (Prosopagnosia): Test, Symptoms, and CausesHealthline
    https://www.healthline.com/health/neurological-health/face-blindness
    Face blindness, or prosopagnosia, is a rare brain disorder characterized by the inability to recognize or differentiate faces. […] People with face blindness may have difficulty noticing differences in the faces of strangers. Others may even have a hard time recognizing familiar faces. […] The most common symptom of face blindness is an inability to recognize or discriminate between faces. This may make forming relationships more difficult, both in a personal and professional setting. […] People with minor prosopagnosia may just struggle to differentiate or identify faces of strangers or people they don’t know well. Those with moderate to severe face blindness may struggle to recognize faces of people they see regularly, including family members and close friends. […] In very severe cases, people with face blindness may not recognize their own faces. This may cause social anxiety or depression.
  • #17 Understanding Prosopagnosia – Faceblind
    https://www.faceblind.org/research/
    Prosopagnosia, also called face blindness, is an impairment in the recognition of facial identity. Prosopagnosics often have difficulty recognizing family members, close friends, and even themselves. […] Prosopagnosics have difficulty knowing whether they have seen a face before, and they often have problems recognizing faces they have encountered many times. In extreme cases, prosopagnosics have trouble recognizing even those people that they spend the most time with such as their spouse and children. […] One of the telltale signs of prosopagnosia is great reliance on non-facial information such as hair, gait, clothing, voice, and other information. […] Developmental prosopagnosics have never recognized faces normally so their impairment is often not readily apparent to them. As a result, many developmental prosopagnosics are unaware of their prosopagnosia even as adults.

    Face blindness (prosopagnosia) People with face blindness have difficulty recognizing the faces of people. […] Prosopagnosia is a brain disorder characterized by the inability to recognize or differentiate between faces of people.

    People with prosopagnosia cannot recognize familiar faces and often cannot distinguish among the faces of strangers. […] They may also have trouble recognizing familiar places or objects or recognizing the difference between a person’s face and another object. Some people with prosopagnosia even have difficulty recognizing themselves. […] When it comes to prosopagnosia, “face blindness” is a bit of a misnomer. Someone with this condition might be looking directly at a person’s face, but be unable to see the entire visage. They might only be able to focus on and identify individual features. Once the face is out of their field of vision, they are unable to retrieve any memory of it. In addition to face blindness, people with prosopagnosia may find it difficult to recognize facial cues and remember places.

You’ll still see the parts of a face normally, but all faces may look the same to you. […] It affects people differently. Some people may not be able to tell the difference between strangers or people they do not know well. Others may not recognise the faces of friends and family, or even their own face. […] Other symptoms of prosopagnosia can include difficulty with recognising emotions on people’s faces, recognising people’s age and gender, recognising characters and following plots in TV programmes or films, recognising other things, such as cars or animals, and finding your way around.

    Face recognition is a highly complex cognitive process involving a dedicated network of brain regions. Prosopagnosia may present as degrees of impairment — some people are mildly affected, others might not recognize their own reflection. […] The onset of prosopagnosia, Postal says, depends on what caused it. With a stroke, it’s sudden: A patient wakes up in the hospital and recognizes the person keeping vigil at their bedside only when they speak. For those with dementia, there might be a slow decline in the ability to recognize faces. […] Some days the symptoms might be more prominent, “the next less so, but the trajectory is for increasing problems over time,” Postal says. “In the case of developmental prosopagnosia, it is usually a parent’s dawning realization that a child cannot distinguish one face from another.”

    Face recognition is an ability that develops through childhood, only reaching full maturity in mid-adolescence. However, if a child exhibits a number of these symptoms it may be worth considering whether they might have face blindness, particularly if other family members also have difficulty recognising familiar faces. Children with Prosopagnosia may: Fail to recognise familiar people […] Have difficulty making friends and appear withdrawn […] Mistakenly approach strangers […] Wait for you to wave before coming up to you at the school gate […] Have difficulty following TV shows (preferring cartoon characters) […] Appear distracted (seeking clues to someone’s identity from their shoes, bag etc) […] Failing to recognise someone when their appearance changes (e.g. their hair style or colour)
  • #29 Prosopagnosia in Childhood
    https://lab.faceblind.org/dpkids/dpkids
    Developmental prosopagnosia (DP), also known as congenital prosopagnosia, is defined by extreme difficulties with face recognition resulting from the failure to develop the necessary neural mechanisms for processing faces. Many individuals with DP are unable to recognize even very familiar faces. They struggle with the faces of family and friends, and some even fail to recognize their own face in a mirror. […] DP is estimated to affect 2-2.9% of the population, and there are many different factors that are thought to contribute to a person’s risk of DP. These include genetic factors, neurological factors, and experiential factors. Exposure to faces at an early age is crucial to the development of normal face recognition abilities. […] Prosopagnosia can be difficult to identify because individuals with the disorder have normal intelligence and otherwise normal vision. In addition, abnormal behaviors that are often associated with prosopagnosia, such as social avoidance and failure to make eye contact, can be mistaken for other disorders, such as autism spectrum disorder. People with prosopagnosia often experience failure to recognize someone, especially if they have changed their appearance or are seen out of context, anxiety and fear that they will be unable to recognize friends or family members, loss of self-confidence due to social isolation, avoidance of social situations, and past social embarrassment, and difficulty following the plots of TV shows with human characters, as they can fail to recognize a character after a change in scene and/or clothing.

    Prosopagnosia is defined as the inability to recognize known and new faces. It is also known as facial/visual agnosia. There are varying degrees of impairment in prosopagnosia, including: The inability to recognize, Discriminate, Identify different or own faces, Discern differences between faces and surrounding objects. This impairment causes a psychological and social impact leading to functional impairment, unemployment, social isolation, depression, anxiety, and other mood disorders. Prosopagnosia can be acquired or hereditary. Acquired cases can result from ischemic or hemorrhagic stroke, traumatic brain injury, certain neurodegenerative and neuropsychiatric illnesses (Alzheimer disease, depression, and schizophrenia). The prevalence can approach 2.5% of the population. Patients with juvenile prosopagnosia cannot recognize faces throughout their life, and a strong family history is usually present. Variants of prosopagnosia include an apperceptive variant (deficits in facial structure perception), and amnestic or associative variant (unable to remember faces even though they can perceive them; the perceptual information cannot access facial memories because of a disconnection or loss of them). The pathophysiology is still not completely understood and is a prominent area of research. Diagnostic tests can divide into three main types. First, perception tests that can accurately evaluate the patient’s ability to discriminate between different visual facial stimuli. Second, recognition tests that can specifically assess short and long term recognition patterns of faces. Third, facial identification tests that involve other auditory or tactile cues (such as naming) to help identify facial stimuli. Advanced imaging is a research tool that uses properties such as cortical thickness, functional activation, and connectivity to study the networks involved in different types of prosopagnosia. At this time, there is no evidence-based study that guides the creation of an interdisciplinary team for prosopagnosia.

    Diagnosing prosopagnosia is difficult because there is no clear line between this condition and having a below-average ability to remember faces. There are neurological and sensory tests that ensure healthy vision, as well as other tests to rule out any mental deficiencies, and for memory and the ability to identify objects, to rule out any kind of blindness the inability to perceive a sensory stimulus. There are also diagnostic tests, such as Computerized Tomography (CT) scans, Electroencephalogram (EEG), and Magnetic Resonance Imaging (MRI); in addition to special tests for facial recognition, such as the Benton Face Recognition Test (BFRT), in which a person is asked to match a given face to one of six presented faces that are not distinguished by anything, such as hair or hats. […] To date, there is no treatment for prosopagnosia; however, if the reason for this condition is curable, whether medically or surgically, it would be a feasible solution. Other cases are trained to adapt to this disorder using different tip-offs to recognize people, such as the speaker’s voice, clothes, hairstyle, perfume, height, and ornaments. Several questions remain about this disorder, as well as attempts to understand and find ways to cure it.

    Prosopagnosia is defined as the inability to recognize known and new faces. It is also known as facial/visual agnosia. There are varying degrees of impairment in prosopagnosia, including: The inability to recognize, Discriminate, Identify different or own faces, Discern differences between faces and surrounding objects. This impairment causes a psychological and social impact leading to functional impairment, unemployment, social isolation, depression, anxiety, and other mood disorders. Prosopagnosia can be acquired or hereditary. Acquired cases can result from ischemic or hemorrhagic stroke, traumatic brain injury, certain neurodegenerative and neuropsychiatric illnesses (Alzheimer disease, depression, and schizophrenia). The prevalence can approach 2.5% of the population. Patients with juvenile prosopagnosia cannot recognize faces throughout their life, and a strong family history is usually present. Variants of prosopagnosia include an apperceptive variant (deficits in facial structure perception), and amnestic or associative variant (unable to remember faces even though they can perceive them; the perceptual information cannot access facial memories because of a disconnection or loss of them). The pathophysiology is still not completely understood and is a prominent area of research. Diagnostic tests can divide into three main types. First, perception tests that can accurately evaluate the patient’s ability to discriminate between different visual facial stimuli. Second, recognition tests that can specifically assess short and long term recognition patterns of faces. Third, facial identification tests that involve other auditory or tactile cues (such as naming) to help identify facial stimuli. Advanced imaging is a research tool that uses properties such as cortical thickness, functional activation, and connectivity to study the networks involved in different types of prosopagnosia. At this time, there is no evidence-based study that guides the creation of an interdisciplinary team for prosopagnosia.

    Prosopagnosia is the inability of the brain to process the visual information about facial features that the eyes send to the brain. There can also be an inability to retain or recall the memory of information associated with a face. […] Prosopagnosia can occur following a stroke, trauma to the brain, or neurodegenerative diseases. […] Currently, there is no cure for face blindness. Treatment of prosopagnosia is mainly supportive and involves developing coping mechanisms to help manage the condition better. […] Face blindness can lead to the following complications: Depression, Social anxiety, Social withdrawal, Lack of confidence, Difficulty building and maintaining relationships, Difficulty following characters in movies or TV shows. […] Face blindness cannot be cured with our current knowledge of the condition.

    Developmental prosopagnosia appears during childhood and may have genetic roots or arise as a result of a prenatal or childhood brain abnormality or damage. Acquired prosopagnosia can occur in older men and women after a brain injury, stroke, or the onset of degenerative disease. […] There is currently no cure for prosopagnosia. Treatment focuses on the development of compensatory skills for recognizing individuals, including friends, family members, and acquaintances, such as attending to cues like unique physical characteristics or voice. […] An area of the brain called the fusiform gyrus is responsible for recognizing human faces in greater detail than similarly complex but inanimate objects. It is also thought to be connected with memory. One theory states that prosopagnosia occurs when the fusiform gyrus is deformed or damaged in some way. […] While there is no cure for the prosopagnosia itself, people with this condition may experience symptoms of anxiety or depression that can be alleviated with the help of a professional.

    Currently, there is no cure for prosopagnosia. However, several strategies can assist individuals in managing the condition: Non-Facial Cues: Encouraging the use of other identifying markers such as voice, clothing, or distinctive features. Environmental Context: Associating people with specific environments or contexts to aid recognition. Technological Aids: Utilizing apps and devices designed to assist with facial recognition and memory. […] Acquired prosopagnosia, often resulting from brain injury, presents unique challenges. The sudden loss of facial recognition ability can be particularly distressing, affecting personal relationships and professional life. […] The ability to recognize faces is deeply intertwined with social perception and personal identity. Prosopagnosia can impact one’s self-esteem, social interactions, and sense of belonging. Raising awareness about the condition is essential in fostering understanding and empathy within the community.

    Prosopagnosia sufferers deal with significant practical and social difficulties. Some are dismissed as “snobs” or unfriendly, and Gilbert says the condition means she sometimes struggles to understand deep emotion. […] “It’s not that I don’t care about the people in my life, but when I’m not with them, they are no longer in my head. I have no face to remember, nothing to attach an emotion to,” she said. “Imagine going on vacation by yourself. You can recall the places you visited, the food you ate and the things you did, but there are no people in the memories. That’s been my life from the time I was born. It can be lonely.” […] Experts agree, however, that most prosopagnosics develop strategies to compensate. […] Gilbert says she is upfront about her condition now: “I come right out and say, ‘Have we met before? I have face blindness and can’t recognize people, not even myself.’ My real friends come up to me and say their names and remind me what we last did together. I call those my memory prompts. I may not have the person in my memory, but I can recall an event or conversation.”

    A handful of treatments are available for face blindness, some that target fixing the impairment, while others provide ways to work around it, says Joseph DeGutis, a collaborator at Faceblind.org and director of the Boston Attention and Learning Lab. […] He say his lab and others have “focused on improving face perception abilities, for example, by enhancing matching internal facial features or improving holistic processing abilities: the ability to integrate all the parts of the face into a single representation.” […] The lab has developed a training approach focused on memory to improve “face encoding strategies to enhance face recollection,” DeGutis says, because those with prosopagnosia typically lack “the ability to automatically recall semantic and contextual details when they see a face, although they may have a vague feeling of knowing.”

    Although face blindness causes difficulty recognizing and remembering faces, it is not associated with memory impairment or intellectual deficits. The affected person has normal learning abilities and vision. […] Currently, there is no specific cure or treatment for face blindness. The affected person, however, can learn ways to cope with the disease with the help of doctors or therapists. They can help the person develop other mechanisms to identify people rather than their face alone. This may be through their hair, gait (way of walking), voice, or the way they dress. Face blindness may cause significant social anxiety and stress and may even lead to depression. Appropriate and timely help from a qualified psychiatrist must be obtained to cope with these problems. Children with face blindness may need particular care so that they are not harmed due to their inability to identify parents or caregivers. A pediatric psychologist may help build the childs confidence and allay any anxiety due to the condition.

    Approximately 2.5% of all people are thought to be born with facial blindness and have difficulty with facial recognition. […] Acquired prosopagnosia is currently believed to impact approximately one in 30,000 people worldwide. […] Depending on the cause of brain damage, facial processing difficulties may be reversible, and a person may retain the ability to recognize familiar faces. […] Because prosopagnosia usually impacts the way individuals view those they love, the condition can lead to significant mental distress and may be associated with conditions like depression and anxiety. […] Because facial blindness is a neurological condition often caused by severe brain damage or genetics, it is generally not considered “curable.” […] However, some people with acquired face blindness may find that it is a temporary condition for them, as in the case of a stroke or seizure whose impacts heal over time.

[…] We aim to assess demographic, clinical and imaging characteristics and neurological and neuropathological disorders associated with a diagnosis of prosopagnosia in a large cohort. […] The most common degenerative diagnoses were posterior cortical atrophy, primary prosopagnosia syndrome, Alzheimer’s disease dementia and semantic dementia, with each diagnosis accounting for >10% of this group. […] We identified a group of patients with non-degenerative transient prosopagnosia in which facial recognition loss improved or resolved over time.

    Prosopagnosia or “face blindness” is a neurological condition in which someone can’t recognize another person’s face, even someone they know well. It appears to be a “disconnect” between otherwise normal visual input and the brain functions that translate that input into facial recognition. […] While many cases are permanent (often congenital or caused by stroke, injury, or degenerative brain disease), a recent study revealed that’s not always the case — especially when it’s connected to migraine. […] Two of the most interesting findings in the patients with a non-degenerative diagnosis were the association of prosopagnosia with migraines and the observation that prosopagnosia can be transient and resolve over time. […] Prosopagnosia as a feature of classic migraine is rarely described in the literature since the first report over two decades ago.

[…] Despite the lack of clear treatments, it remains helpful to get diagnosed, DeGutis said, because it provides insight into how poor someone is at face recognition whether they are at the lower end of normal or truly at a disadvantage. […] It’s not that people with prosopagnosia can’t ever recognize a face, but it takes a lot more exposures for that face to become familiar. […] It is possible to improve facial recognition with practice, DeGutis said, though it’s not a cure and it’s not easy.

    Prosopagnosia is a neurological disorder characterized by the inability to recognize faces. Prosopagnosia is also known as face blindness or facial agnosia. Depending upon the degree of impairment, some people with prosopagnosia may only have difficulty recognizing a familiar face; others will be unable to discriminate between unknown faces, while still others may not even be able to distinguish a face as being different from an object. Some people with the disorder are unable to recognize their own face. Prosopagnosia can result from stroke, traumatic brain injury, or certain neurodegenerative diseases. In some cases it is a congenital disorder, present at birth in the absence of any brain damage. Children with congenital prosopagnosia are born with the disability and have never had a time when they could recognize faces. Prosopagnosia can be socially crippling. Individuals with the disorder often have difficulty recognizing family members and close friends. […] Prosopagnosia is thought to be the result of abnormalities, damage, or impairment in the right fusiform gyrus, a fold in the brain that appears to coordinate the neural systems that control facial perception and memory.

Similar to enduring blindness or hearing loss, face blindness can be a hugely isolating condition that has a profound impact on those living with it. […] In order for the brain to recognize a face, an extremely intricate series of neurons in the occipital and temporal lobes must work in conjunction. Damage to any part of the neural network that decodes facial features can cause face blindness to develop. […] In cases of acquired face blindness, there have been several studies to determine the root cause of the issue. Unfortunately, because of the complex nature of the cognitive system governing facial recognition, a lot of different ailments can result in someone being unable to recognize faces, even those belonging to family members.

    Psychologists learned more about face blindness (prosopagnosia), a neurological condition that makes it difficult to distinguish one face from another. Researchers have been working to learn more about face blindness (prosopagnosia), a brain disorder affecting an estimated 2 percent of the population that makes it difficult for people to distinguish one face from another. People with face blindness showed less activity in regions of the brain associated with nonvisual knowledge as well as less connectivity between visual and nonvisual regions. We found that activity in these nonvisual regions was significantly reduced as was the connectivity between the visual and nonvisual regions. The condition can vary in severity, ranging from having trouble recognizing acquaintances to being unable to recognize partners or even their own faces. People can be born with prosopagnosia (congenital prosopagnosia) due to issues in the initial wiring of the brain’s facial perception network or it can be acquired as the result of damage caused by a brain tumor, stroke, head trauma or Alzheimer’s disease. There is no cure for facial blindness. Currently, people experiencing problems should talk to a healthcare provider to find behavioral and physical therapies to help cope and compensate for the condition. The findings also suggest that people with face blindness have difficulty reading social situations because they are unable to use nonvisual information about people.
