Abstract

OBJECTIVE:

Given the widely recognized genetic basis for Gilles de la Tourette syndrome (TS) and the suggestion that the putative TS gene(s) may be expressed as or associated with a variety of psychiatric illnesses, this study was undertaken to assess the prevalence of tics and TS in a psychiatric inpatient population.

DESIGN:

Cross-sectional study.

SETTING AND PATIENTS:

200 consecutive adult patients who were admitted to the psychiatric wards of University College London Teaching Hospitals.

OUTCOME MEASURES:

TS and related behaviours, as assessed by the comprehensive semi-structured National Hospital Interview Schedule.

RESULTS:

None of the 200 patients had definite TS, but 2 were observed to have motor tics; 10 had a history of tics (present for less than a year), and 7 reported a family history of tics. Thus, 19 (9.5%) inpatients qualified for inclusion in a broadly defined TS diathesis. These rates are significantly lower than those reported in a similar community based epidemiological study of adolescents (p = 0.018).

CONCLUSIONS:

Our findings do not support the theory that TS and related behaviours are over-represented among adult inpatients with psychiatric illnesses.
