I have an 8 year old son that has been on multiple different medications for his ADHD. He started out on Ritilin and immediately developed a tick. He was blinking constantly. He was switched to Adderol and the blinking slowed but he developed another one. He would open his mouth as far as he could like he was trying to stretch his jaw out. He was switched to Clonidine and the ticks were still there. The dr had me take him off all of the medications during the summer so we knew they were all out of his system. All summer long the blinking continued. About a month before school started we started him on Focalin and it seemed to really help acedemically but the blinking got worse. He is now on Intuniv and the jaw thing has come back. Last year he went from barely passing the 2nd grade to getting straight A's. The medicine is helping him socially and acedemically but I am getting worried that there might be some underlying problem because the ticks have never gone away.View Thread
