PLEASE CHECK THIS OUT. Lemmy's own, and a good buddy of mine, Aeronmelon is going through some shit at the moment and could use some help. Check it out here and consider an upvote or a comment to push it into activity. Sorry, not something I do often or will be spamming. But I care about my friend and if I can get a couple more eyes on his situation then I'm going to try to do what I can.
Pretty sure it's an ADHD thing. I'm like that with people's faces. For a long time I thought I had facial blindness but realized a couple of years ago, I'm just not generally paying attention to faces enough to record them into memory. When I actually learn what someone's face looks like instead of their general shape/hair/clothes/accessories, I have no problem recognizing them in a variety of situations.
