Prosopagnosia is a neurological disorder characterized by the inability to recognize faces. It is also called "facial blindness" or "facial agnosia" (as a subtype of the visual agnosia).
Its name derives from two Greek terms: prosopon (face) and agnosia (lack of knowledge).
Oliver Sacks is probably one of the most recognized neurologists in the world. He is the author of the book "The man who mistook his wife for a hat". All his knowledge about neurology has not prevented him from also suffering from Prosopagnosia as is reflected in the following video:
A triple categorization has been proposed for prosopagnosia:
Occasionally, prosopagnosia has been described as the opposite of Capgras syndrome. People who suffer from this syndrome perfectly recognize the visual representation of their family and friends but believe that they are actually imposters with the same appearance.
The main cause of prosopagnosia is injuries caused by a trauma craniocerebral or by infections that affect the Central Nervous System. Even so, cases of prosopagnosia have also been found congenital present from birth.
There is a movie called "The face of the murderer " that (without going into assessing its cinematographic quality) tries in a more or less creative way to get the viewer to put himself in the shoes of a person suffering from this disorder. Below you can see the trailer.
Below you can see several short videos, interviews and documentaries that I have found about this disorder and have found them interesting.
