That’s super young. 😉 I was diagnosed at age 45, which is 4 years ago. Never too late. I think it’s easier when you’re diagnosed young. It avoids a lot of “why questions” like:why I can’t do small talk? Why can’t I multitask? Why do I suck at team work? Why I get things fixed while others can’t? And so on… Placement is a good thing. 🙂
Now that ASD is seen as a more common and more research has been done on it diagnosing it has been done at an earlier, so while there are some adults who weren’t diagnosed until the age of say 45, or 22, it is becoming less common to see someone diagnosed that late. Especially with the current culture popularizing autism and aspergers. I myself was not diagnosed until i was 16 which is currently considered a “late” diagnosis by most.
