Prosopagnosia - Wikipedia

.. a cognitive disorder of face perception in which the ability to recognize familiar faces, including one's own face (self-recognition), is impaired, while other aspects of visual processing (e.g., object discrimination) and intellectual functioning (e.g., decision-making) remain intact.

I believe I have this condition although have never been officially diagnosed (not even sure if there is a way to diagnose it clinically). However it has led to some extremely embarrassing situations!
