my son Ryan has got adhd and he developed tourettes aged 10 (hes 21 now) as a part of it all, it was absolute hell for him and if one more person had told me I had a nasty/wierd son I swear i would have whacked them , he developed a twitch more then the swearing but he did swear when stressed, luckly with pills he managed it and now he can manage it totally, so much so you would'nt know about it, think it could raise its horrible head again if he got badly stressed , so I know what its like to live with it, hope they dont this guy a bad time , he cant help it, I'm surprised they let him on it to be honest, he must have a great deal of confidence to cope with the remarks,
