Prosopagnosia

Excerpt

Prosopagnosia is defined as the inability to recognize known and new faces. It is also known as facial/visual agnosia. Bodamer first used the word prosopagnosia in 1947 in a landmark paper that described the cases of two patients with face recognition deficits. The word comes from Greek prosopon, meaning face and agnosia, meaning lack of knowledge. Normally, an individual can recognize and remember 5000+ faces throughout their lifetime.
