Prosopagnosia is an unusual neurological impairment that renders a person unable to do what?

Also known as face blindness, prosopagnosia (from Greek prósōpon, meaning "face", and agnōsía, meaning "non-knowledge") is the inability to recognize familiar faces - including one's own face. What's extraordinary is that the rest of the person's visual (and mental) processing is totally unaffected. In severe cases, the afflicted person may not be able to tell the difference between a familiar person's face and a physical object - a condition illustrated in the title story of the Oliver Sacks best seller, The Man Who Mistook His Wife For a Hat.
