A diagnosis of Tourette’s requires multiple motor tics and at least one verbal tic.

EDIT: “vocal,” I should say, not “verbal”

> Tics are sudden twitches, movements, or sounds that people do repeatedly. People who have tics cannot stop their body from doing these things. For example, a person with a motor tic might keep blinking over and over, or a person with a vocal tic might make a grunting sound unwillingly.

> The tic disorders differ from each other in terms of the type of tic present (motor or vocal, or a combination of both)
