Brad Pitt says he has face blindness. So what is prosopagnosia?

Brad Pitt says he believes he has prosopagnosia, a neurological disorder characterized by the inability to recognize faces

The condition, also known as "face blindness," can effect as many as 1 in 50 people

 according to Faceblind.org, which researches the disorder. 

The 58-year-old actor, who has never been formally diagnosed with the condition

has said in the past that he struggles to remember and recognize faces, and that has made him seem aloof, he told GQ

 He said he's ashamed of it and said he wants to meet another person who can relate. 

Prosopagnosia affects people in varying ways. Some people can't recognize familiar faces

even their own family members, according to the National Institute of Neurological Disorders and Stroke (NINDS)

The disorder can be caused by several things – a stroke, traumatic brain injury, or certain neurodegenerative diseases

 But it can also be a congenital disorder, present at birth, and it appears to run in families

That means, it is likely to be the result of a genetic mutation or deletion. 

Some children with autism can also have some degree of prosopagnosia, according to NINDS.
