PROSOPAGNOSIA. !!!!!!

Prosopagnosia , or face blindness.  I suffer from it and have done so for as long as I can remember.  Does anyone else here have similar problems?

It's very embarrassing when someone greets me and I have no idea who they are or where do I know them from.  Related to this problem is name blindness where I find it very very difficult to remember people's names.

Recently I was greeted by a man in a park and I struggled badly to remember who he was.  I mostly remember people from their voices and other visual clues such what they wear, where they usually sit.  He turned out to be a colleague from a health and fitness course I recently attended.

How common is it for autistics to suffer from prosopagnosia ?
