Tourette syndrome

Description

Tourette syndrome is a chronic tic disorder characterised by the presence of both chronic motor tics and vocal (phonic) tics, with onset during the developmental period. Motor and vocal tics are defined as sudden, rapid, non-rhythmic, and recurrent movements or vocalizations, respectively. In order to be diagnosed as Tourette syndrome, both motor and vocal tics must have been present for at least one year, although they may not manifest concurrently or consistently throughout the symptomatic course.
