While I was at court for my client that was getting his carry permit, the case in front of mine was a guy that was denied because when he was in second grade (20 or so years ago) they thought he was ADD and he saw a school doctor for about a year.  It never really went anywhere and the guy has never had any other problems. In fact, the guy didn’t even remember it as it was so long ago.  Nevertheless, his permit was denied.

Of course, the State wasn’t  really going anywhere with this as they had no proof that he suffers from any disability.  Thus, his attorney was able to win the case.  However, he probably spent a good amount of money for the appeal whereas he could have saved a lot of money if he had hired one to begin with.
