In a recent interview, actor Brad Pitt disclosed that he had prosopagnosia, a rare neurological condition commonly referred to as “facial blindness.”

In a New York Times article, Dani Blum outlines the disorder’s symptoms, underlying causes, and treatment options.

Prosopagnosia symptoms

The primary symptom of prosopagnosia, according to behavioral neurologist Borna Bonakdarpour of Northwestern Medicine, is face blindness rather than color blindness or general vision impairment.

According to the National Institute of Neurological Disorders and Stroke, there is no link between the condition and learning disabilities, vision issues, or memory loss. It is not the same as forgetting or occasionally having difficulties finding the right term, argues Blum.

A close friend or relative’s visage, for instance, could be difficult for some people to recognize, while their own reflection might be challenging for others to recognize. Furthermore, some persons might not be able to identify faces from objects.

Notably, some evidence suggests that people with prosopagnosia may have chronic anxiety or depression as a result of the isolation and fear that are typically linked to the condition.

Blum points out that some people shy away from family members and other close friends out of worry that they won’t be able to identify with or appreciate them in a meaningful way. It can be challenging to navigate fundamental social interactions when one has prosopagnosia, she adds.

In a recent interview with GQ, Pitt acknowledged that he has had problems recognizing people’s faces for years despite never receiving a formal prosopagnosia diagnosis.

In fact, Pitt stated in a 2013 interview with Esquire that he regularly felt the need to separate himself because of how difficult it was for him to recognize people’s faces. That’s why I stay at home, he said.

What is the root of the problem?

Prosopagnosia can either be a congenital condition or an acquired one, and most people who are diagnosed with it fall into one of these two groups.

However, estimates show that up to one in every 50 individuals may battle with the disorder throughout the course of their lives, and scientists theorize that it may run in families. Research, in the words of Blum, “suggests that congenital, or lifelong, prosopagnosia is less prevalent.”

Children who are born with the condition “don’t seem to have any visible structural abnormality” in the brain, according to Andrey Stojic, director of general neurology at the Cleveland Clinic. Notably, because congenital prosopagnosia patients don’t have any evident brain lesions, medical professionals are unsure of what exactly causes the condition.

Those who experience prosopagnosia later in life, however, may have brain abnormalities brought on by a traumatic event or head injury. According to Bonakdarpour, people can also have prosopagnosia after having a stroke or when dealing with Alzheimer’s disease.

What prosopagnosia treatments are available?

As of right moment, prosopagnosia cannot be treated, claims Bonakdarpour. But the issue can be resolved. People with the syndrome typically make an effort to tell people apart by focusing on physical traits like voice, stride, or hair color.

Neurologists typically reach the diagnosis with the aid of a battery of exams that gauge a person’s memory and face recognition abilities. Blum continues, “it can be a drawn-out process because doctors frequently take care to confirm that a patient’s face blindness is not a sign of a more severe degenerative neurological illness.

It’s interesting to note that many sufferers of the condition, like Pitt, won’t receive a formal diagnosis. According to Stojic, many of the challenges he is describing and the problems he is facing are common occurrences for people.

It might be relatively debilitating for some, he continued.Others find it challenging to understand.
