Colin, another child who suffers from Tourette's, isn't shy about his disease. His mother Dorene even says he's an advocate of sorts for other children with the neurological disorder.
When Colin feels a tic coming on—like the need to shake his head—he says he can't help but give in to his urges.
"It's kind of like a little man in your head, and he's just saying, 'You've got to tic,'" Colin says. "[The tic] keeps nagging and nagging and nagging at you until finally you just say, 'Okay.' And then you shake your head or you cough or you do whatever."
