Not recognising the faces of others is the symptom known as 
'prosopagnosia'. This is supposedly more common in disorders causing 
lesions in the non-dominant parietal lobe of the brain. Not recognising 
one's own face is 'autoprosopagnosia' or the 'mirror sign'. This can be a 
distressing symptom in Alzheimer's disease, for instance, where the 
patient misinterprets the image in a mirror as a stranger. Many other 
neurological diseases can result in these symptoms which are part of the 
more general class of symptoms resulting in difficulty in reconising a 
variety of images - the agnosias.

Hope this helps
