Have you ever failed to recognize a close friend or family member, blind especially when you see them unexpectedly at a public event or after they get a new hairstyle?
If so, you may have a disorder called prosopagnosia, which is officially called prosopagnosia.
About 1 in 50 people suffer from some degree of facial blindness, although many live normal lives without realizing they have the disorder.
How do you know if you have face blindness?
Symptoms vary widely among people with this condition. Some may find it difficult to recognize the facial expressions of others.
While for some, watching TV or movies can be a daunting task, as people with this condition struggle to remember the different characters at work.
When meeting someone new, people with face blindness may also try to remember their clothes or hairstyle instead of their face, according to the NHS website.
Not surprisingly, another trait commonly associated with face blindness is social anxiety. Because not understanding facial expressions can make it difficult to form relationships, make friends, or interact normally in groups.
People with facial blindness may also avoid social interaction, develop social anxiety disorder, and even experience periods of depression and other mental disorders.
What is the suffering of people with blindness to recognize faces?
Heather Sellers, author of You Don’t Look Like Anyone I Know, told TIME in a 2010 interview that face blindness makes people with the problem look like they have a learning disability. The disorder is likened to “dyslexia” when a person cannot distinguish words.
Studies show that prosopagnosia is not associated with general intelligence or broader memory in the affected person’s mental abilities. It is usually a lifelong problem in sufferers.
The causes of this disorder and the people most susceptible to it
Developmental prosopagnosia, which refers to face blindness without brain damage, is the most common type in sufferers worldwide.
The disorder is also highly heritable, according to the results of a scientific study led by a team of German researchers in 2006.
One of the study’s authors, Thomas Grotter of the Institute of Human Genetics in Germany, speculated that the condition was most likely caused by a defect in a single dominant gene. This could mean that if one parent has prosopagnosia, each child will have a 50% chance of inheriting the disorder.
The aforementioned German study indicates that about 2% of people show signs of developmental face blindness.
Although distinguishing the features of others is among the greatest challenges for people with autism, face blindness is not always a standard symptom of autism, but it appears to be more common in people with autism than in the general population.
Proto-blindness is suppose to be part of what sometimes hinders the social development of people with autism, according to Healthline.
On the other hand, some people also develop face blindness after suffering brain damage, such as a head injury, stroke or concussion. This is known as acquire prosopagnosia, and it is relatively rare compared to the developmental type due to a genetic defect, according to experts.
