As it's a developmental issue, you can't get it once your brain is fully developed.

However, your circumstances change as you become an adult and once well managed symptoms can start showing. You don't see impaired decision making when you can ask your parents about everything. You're not late when mom makes sure you get out one time. You manage all 2-3 household chores you have, but crack when you get 20-30. You manage your pocket money well enough, but not so much a full adult budget. You're fine when you know what you're supposed to be doing (the homework for tomorrow), but adult life gets you overwhelmed. Etc. Etc.
