What does a person with prosopagnosia see?
The former IT professional has a condition called prosopagnosia, sometimes known as "face blindness". But people with prosopagnosia aren't actually blind; they know when they see a face, but their brain can't process who it belongs to.
Can prosopagnosia be cured?
Prosopagnosia is surprisingly common and while there is no cure for prosopagnosia, individuals that have it often adopt compensatory strategies for identifying the persons with whom they deal.
Can you have a mild form of prosopagnosia?
In its most extreme form, people cannot even recognise their family or friends. Milder forms, while still distressing, can be tricky to diagnose, which is why tests are needed. People with prosopagnosia often use non-facial cues to recognise others, such as their hairstyle, clothes, voice, or distinctive features.

What is face blindness?
Face blindness, also known as prosopagnosia, refers to a neurological disorder characterized by the inability to recognize familiar faces. When looking at a face, people with face blindness understand that they are viewing a face; however, they cannot identify individuals. Individuals with face blindness may have trouble identifying a family member or themselves. There are two types of impaired facial recognition: developmental, which is estimated to occur in as many as 1 in every 50 people, and acquired, which is quite rare.
How is face blindness diagnosed and treated?
Although formal diagnostic criteria does not exist for face blindness, diagnosis typically begins with an assessment of the individual’s history and a thorough physical examination. The examination typically involves a range of tests, such as the Cambridge Face Memory Test (CFMT). Individuals may be asked to memorize and later identify the faces of people they have never seen before. They may also be asked to identify famous characters, find similarities and differences between given faces, or estimate someone’s age and facial expression. Physical examination should always involve assessment of visual acuity, which measures the clarity and sharpness of one’s vision and memory, before confirming a diagnosis of face blindness. In cases of acquired prosopagnosia, further diagnostic testing may be needed in order to identify the underlying cause. Blood tests can evaluate the presence of inflammation, and imaging, such as a computed tomography (CT) scan or magnetic resonance imaging (MRI), can reveal brain damage.
What are the most important facts to know about face blindness?
Acquired face blindness is the result of various pathologies that cause brain damage, whereas developmental, or congenital, prosopagnosia presents at birth and without any obvious brain lesions. Those unable to recognize faces often experience difficulties in their relationships, and they may also lack the ability to recognize places and objects. Thorough medical examination, including multiple tests of face recognition and an assessment of visual acuity and memory, can contribute to a diagnosis of face blindness. There are currently no curative medical interventions; however, some measures may help improve recognition abilities.

While there is no presence of obvious brain lesions, several studies have revealed that these individuals may have anatomical differences in regions ...
How does prosopagnosia affect people?
Prosopagnosia is thought to affect many aspects of life. In addition to being unable to recognize faces, individuals with face blindness may have trouble identifying facial expressions of emotion, like anger, surprise, or joy. For those who have face blindness, getting to know new people and forming relationships can be extremely difficult, and social struggles may lead to feeling isolated, lonely, or depressed. It is very common for individuals with face blindness to avoid social interaction and develop severe social anxiety, an overwhelming fear of interacting in social situations.
What is it called when you see only a blurred image of someone's face?

This variety is known as associative prosopagnosia.

How many face-selective areas are there in the brain?
The researchers examined 12 face-selective areas throughout the brain (six face-selective areas in each hemisphere). These are different parts of the brain that are interconnected and form the face processing network. The findings showed that DPs had reduced responses to faces but normal responses to objects, scenes, and bodies across all 12 of the face-selective areas.
Can't remember what faces look like?
Imagine that you're supposed to meet colleagues for dinner, only you can't remember what their faces look like. For some, this is a reality, as people with face blindness or developmental prosopagnosia (DP) have severe difficulties recognizing faces, including those of family and friends, despite having no history of brain damage (e.g., brain trauma, head injuries). A new study finds that developmental prosopagnosia often occurs as a result of a neurobiological problem in the brain, which affects visual recognition broadly.

What causes agnosia in the brain?
Agnosia is usually caused by lesions on the parietal, temporal, or occipital lobes of the brain. These lobes store semantic information and language.

What causes visual agnosia?
Apperceptive visual agnosia is usually caused by lesions to the occipito-parietal cortex.
What is the process of agnosia?
Agnosia occurs when the brain experiences damage along certain pathways. These pathways involve sensory processing areas. These parts of the brain store knowledge and information regarding perception and identification of things. Agnosia is usually caused by lesions on the parietal, temporal, or occipital lobes of the brain.
What is the loss of the ability to recognize objects, faces, voices, or places?
Agnosia is the loss of the ability to recognize objects, faces, voices, or places. It’s a rare disorder involving one (or more) of the senses.

How to diagnose prosopagnosia?
However, this test is difficult to standardize. The Benton Facial Recognition Test (BFRT) is another test used by neuropsychologists to assess face recognition skills. Individuals are presented with a target face above six test faces and are asked to identify which test face matches the target face. The images are cropped to eliminate hair and clothes, as many people with prosopagnosia use hair and clothing cues to recognize faces. Both male and female faces are used during the test. For the first six items only one test face matches the target face; during the next seven items, three of the test faces match the target faces and the poses are different. The reliability of the BFRT was questioned when a study conducted by Duchaine and Nakayama showed that the average score for 11 self-reported prosopagnosics was within the normal range.
How do prosopagnosics learn to recognize people?
Prosopagnosics often learn to use "piecemeal" or "feature-by-feature" recognition strategies. This may involve secondary clues such as clothing, gait, hair color, skin color, body shape, and voice. Because the face seems to function as an important identifying feature in memory, it can also be difficult for people with this condition to keep track of information about people, and socialize normally with others. Prosopagnosia has also been associated with other disorders that are associated with nearby brain areas: left hemianopsia (loss of vision from left side of space, associated with damage to the right occipital lobe), achromatopsia (a deficit in color perception often associated with unilateral or bilateral lesions in the temporo-occipital junction) and topographical disorientation (a loss of environmental familiarity and difficulties in using landmarks, associated with lesions in the posterior part of the parahippocampal gyrus and anterior part of the lingual gyrus of the right hemisphere).
How many faces are used in prosopagnosia?
Individuals are presented with a target face above six test faces and are asked to identify which test face matches the target face. The images are cropped to eliminate hair and clothes, as many people with prosopagnosia use hair and clothing cues to recognize faces. Both male and female faces are used during the test.
