“You meet so many damned people,” he added. “And then you meet ’em again.”

People with prosopagnosia, or face blindness, typically avoid social interactions and can develop social anxiety disorder.

There are two types of prosopagnosia, developmental and acquired, according to the U.K’s National Health Service. Developmental refers to those who have the condition without brain injury, which can be genetic. Studies show 1 in 50 people may have developmental prosopagnosia.

Acquired refers to those who have the condition following brain injury like a stroke or head injury.

Dr. Leah Croll, assistant professor of neurology at Temple University Hospital, recently told Good Morning America that prosopagnosia is “a very real syndrome” that can come with a wide spectrum of symptoms impacting everyday life.

“For some people, it may be just some minor difficulties in remembering people’s names and keeping strangers straight,” she told the outlet. “And for other people, it may be more severe such that they have issues with recognizing their own friends and family or even issues recognizing their own reflection.”

“I think that Brad Pitt is experiencing something that many patients experience which is this funny feeling that something is off, but they’re not quite sure what it is or where to go for help,” Croll continued, emphasizing that she has not diagnosed Pitt herself. “So someone thinking that Brad Pitt story sounds familiar to them or that they’re having similar symptoms, I would recommend they go see a neurologist and get formally tested and evaluated.”

Though there is no treatment for prosopagnosia, therapy can help patients “develop compensatory strategies,” per the NIH.
