Tourette Syndrome and Other Tic Disorders in Children and Adolescents
Classification of Tic Disorders
There are three major types of tic disorder: Provisional tic disorder: Children have had motor and/or vocal tics for less than a year. Persistent tic disorder (chronic tic disorder): Children have had motor or vocal tics (but not both) for more than a year. Tourette syndrome: Children have had both motor and vocal tics for more than a year. Typically, children begin with provisional tic disorder and sometimes go on to develop persistent tic disorder or Tourette syndrome.
