I learned I had a mild form when I was about 40, though I had symptoms dating back to college. Mine is sort of the inverse of yours: I will see someone, I know for certain that I’m supposed to know who they are, but draw a complete blank. Like the instant of recognition wipes my memory. Only happens with people who I encounter out of whatever the normal place would be. e.g. I ran into a former roommate at an airport. Knew I was supposed to know who she was but drew a complete blank (luckily, as a former roommate she knew I had this problem).
