Reports from the MHC data base

Report from the Observation Chart (PDF)



Estimated occurrence

4:5 000 – 10 000 inhabitants


Not completely known. Genetic predisposition but also other factors that may have an effect on the development of the brain during fetal life is thought to cause the symptoms included in Tourette syndrome (TS).

General symptoms

TS is characterized by physical and vocal tics. Other problems that may appear in TS include hyperactivity, concentration difficulties, poor motor skills, compulsive behaviour and problems associated with empathy. There is sometimes overlap between TS and other diagnoses such as ADHD (Attention Deficit Hyperactivity Disorder) and OCD (Obsessive Compulsive Disorder). As a rule, the symptoms present before the age of 18.

Orofacial/odontological symptoms

There is no specific odontological problem complex. Oral motor difficulties including chewing problems, speech difficulties and drooling may occur. Tooth grinding is relatively common.

Orofacial/odontological treatment

  • Speech difficulties and oral motor problems are treated by a speech therapist.
  • Tooth grinding should be followed up and, when necessary, treated with a splint.
