About 6 to 12 out of 100 people have
tics at some time in their lives.1 And about 1 child out of 100 may have
Tourette's disorder.1, 2 It is hard to know exactly how many children with tics may
have Tourette's disorder, especially when the tics are mild.
Boys are about 3 times more likely to have Tourette's disorder than
girls.3
