Recognition blindness, what is the disorder of Enrica Bonacorti and Brad Pitt-

from Danilo de Diodoro

Enrica Bonacorti spoke up about it, saying she shares this issue with Brad Pitt: Some people don’t know how to recognize faces (sometimes they don’t even know theirs). A problem more prevalent than one might think, involving a million and a half people in Italy alone

Everyone knows hundreds while flying faces. An unusual skill that no one needs to learn, because it is innate. And it has always been fundamental to survival: it allows you to distinguish without hesitation between relatives, friends and enemies. However, it suffers from it in a certain percentage of individuals Uncle facial recognitionThis ability weakens from birth.

Talk to Corriere Enrica Bonaccorti, who said he shares this issue with the actor Brad Pitt. It is a disease that he also suffered Luciano de Cresenzo Who told how, at first glance, she had difficulty recognizing even her dearest friends as Marisa Loreto.

How do you know the other details?

Those who find themselves in this situation suffer from Congenital recognition unclea disorder that affects 2-3 percent of the population. The term is derived from ancient Greek Prosopon, which means, in fact, the face. To be able to orientate themselves in the everyday jungle of faces, those affected by this disorder must resort to real tricks. Forced to learn to identify people from Other Signals, such as the haircut, the way of walking, the gestures, and even the clothes that are worn. Sometimes it relies instead on details of the face itself, such as the shape of the mouth or eyebrows, since face-recognition blindness is primarily characterized by perceptual difficulty face as a wholewhile the ability to select its individual details is not affected.

How many are there: data

In addition to the congenital form, there is also an acquired form. In this condition, a person is born with a normal ability to recognize faces, but then loses it, usually after a traumatic event, such as a stroke or brain trauma. In any case, it is a disorder that can have a significant impact on social life.
People who are blind to face recognition have a large percentage Difficulties in daily lifesays Professor David Revolta, co-author of School of Psychology fromUniversity of East London, author of Faceblindness: A World of Equal Faces (Ferrari Sinibaldi, Milan). For example, they do not get acquainted with the heroes of films, but they also do not recognize family members, such as neighbors, if they meet them outside the usual context. In severe cases, diagnostic etiopathology is not even able to recognize their faces. In Italy, it is estimated that there are about one and a half million people suffering from congenital prosopagnosia, even if they are mostly unknown and discovered.

Diagnostic difficulty

The reasons for this refusal can be different. Since we are born without this ability, we tend to think that difficulties are the norm and that everyone has difficulty recognizing faces. Furthermore, this disorder is rarely mentioned and children are not tested for their ability to recognize faces. Added to this is the fact that psychologists, psychiatrists, and neurologists are often unable to diagnose facial blindness, if not for a while. Revolta explains again that there is no universal diagnosis of prosopagnosia. However, reliable tools exist today. The foremost one memory test, Cambridge face memory test, which requires people to learn and then recognize unfamiliar faces amidst many distractions. Another test we developed is to distinguish between famous and non-famous people. People with face-recognition blindness generally find it difficult to perform these tests correctly. A neuropsychologist is the professional reference person capable of diagnosing and interfering with face blindness.

Other disturbances with objects or objects

Efforts are also being made to identify technologies that can improve facial recognition in those with face-recognition blindness. Professor Rivolta’s group was published in the journal Neuropsychology A study in which the potential beneficial effects of brain stimulation With a very slight current in the areas designated for facial recognition. Acquired prosopagnosia may be associated with disturbances in other cognitive domains, such as failure to recognize objects. In fact, the areas of the brain responsible for recognizing faces and objects are close together, so the lesion, even if it primarily includes the area of ​​faces, can also affect the area of ​​​​the faces. getting to know things. Furthermore, congenital prosopagnosia may be associated with difficulty with spatial orientation or difficulty recognizing corpses, supported by changes at the temporal lobe level. “We observed this phenomenon during a study of 11 people with face blindness, compared to a control group,” Revolta says. The study published in Quarterly Journal of Experimental Psychologysuggests that these difficulties may be underpinned by altering common neurobiological processes.

Watch the monsters

Changes in the perception of faces can also occur monsters. In these cases, it’s no longer about face blindness, it’s about Prosoptometorphosis, i.e. the transformation of faces. A rare syndrome, a case of which was described in the journal Lancet by a group of Dutch neuroscientists, to whom the famous neurologist and writer Oliver Sacks referred the patient. A 52-year-old woman from adolescence had seen the image of dragon faces suddenly appear before her eyes, while the faces of the people around her also turned into dragon faces: suddenly the facial skin of relatives and friends became gloomy, features lengthened, ears grew, eyes swelled and took on a bright color, Yellow, green, blue or red.
