Abstract
Aim: Correctly diagnosing repetitive behaviors in patients with Tourette syndrome (TS) can be challenging.
The differential diagnosis between tics and stereotypies is of particular importance, because of treatment
implications. Methods: We assessed the prevalence and clinical characteristics of stereotypies in a large
sample of adult patients with TS attending a specialist clinic. Results: Mild stereotypies were reported
by 21/148 patients (14.2%). Patients with stereotypies were significantly more likely to have a comorbid
diagnosis of Asperger syndrome, attention-deficit and hyperactivity disorder, and obsessive-compulsive
disorder, compared with patients without stereotypies. Multiple linear regression analysis revealed that
the presence of Asperger syndrome significantly predicted stereotypy severity. Conclusion: Stereotypies
are not rare in adults with TS and other neurodevelopmental conditions, especially Asperger syndrome.
