- n. A form of visual agnosia characterised by difficulty with face recognition despite intact low-level visual processing. Also known as PA.
Apparently derived from the German title of a 1947 paper by neurologist Joachim Bodamer describing the condition, titled Die Prosop-Agnosie, derived from Ancient Greek πρόσωπον (prosopon, "face") and αγνωσία (agnosia, "non-knowledge"). (Wiktionary)
