movie in which the hero has the mental disorder to shout in between the conversation?

Hallmark Hall of Fame, "Front of the Class" (2008)

IMDb synopsis:

This is based on the true story of Brad Cohen (Jimmy Wolk), who, after being challenged by Tourette's Syndrome from a very young age, defied all odds to become a gifted teacher.

I think there might be a couple of others, but I'd have to look around for them as I haven't seen them, only read about them.

EDIT: The Tic Code (1999)

IMDb synopsis:

A 10-year-old gifted boy wants to be a jazz pianist much to the chagrin of his more classical-oriented piano instructor. With his mother's help, he is an underage regular at a local nightspot, where he is teamed up with a sax superstar. Both come to learn that each suffers from Tourette's Syndrome (thus the film title). The older man has developed mannerisms to cover up his own fallibilities and resents the boy and his mother's acceptance of the disease.
