It's a lot better recognized and studied than it was in the 80s and 90s. Especially the recognition that while for some it goes into remission (somehow???) or at least becomes sub-clinical, there are a large number of us who continue to struggle with it our whole lives. It's kind of demeaning when it's seen as a children's disorder.

When you're a kid it's not that bad cos you have structure provided for you and little to no responsibility. You're just a constant pain in the ass. That's why it's named after all the things that piss people off about it and not named after what the lived experience is like or how it affects us internally. When you're an adult and you are responsible for structure and getting things done and holding down job it can silently and slowly crush you. It's a much bigger problem once you're an adult.
