The term refers to fast repetitive movements which are frequently stereotyped and are alterable at will.
Tics occur most often in school-going children and usually represent emotional disturbance or Mal- adjustment. Generally, they may be an outlet for the suppressed anger and worrysomeness following control of aggression by the parents or the teacher.
A kind of tics in which extensive and varied bodily movements are accompanied by vocalization (barking or shouting obscene words) has been termed as Gills de la Tourette syndrome.
Severe variety of tics requires psychiatric evaluation. In Tourette syndrome, 1 to 5 mg haloperidol, given orally daily, as such or together with an antiparkinsonian drug, is indicated.
