Abstract

The aim of this study is to foster an understanding of the clinical characteristics, in terms of general psychopathology, of Tourette syndrome (TS), as it manifests in adolescent patients, and to compare these results with those of previous studies conducted in Western countries. In total, 38 male and 5 female adolescent patients who visited a pediatric neurological specialty clinic for TS between 1 January and 1 March 2003, and who met the World Health Organisation criteria for TS, were studied. These patients were clinically interviewed and assessed with the Symptom-Checklist-90-R, Family APGAR and Tic Symptoms questionnaire, a self-report questionnaire based on DSM-IV TS diagnostic criteria. Among this population, the mean age of onset of motor tics was 9.65 +/- 3.7 years, and motor tics of the head and eyes were usually the first symptoms to manifest; coprolalia occurred in 44.1% (n = 19) of our patients. Many of our findings were similar to those reported in trials conducted in other regions of the world. TS symptoms showed stronger correlation with emotional distress in older patients.
