Objectives: Tourette syndrome is a disorder with motor and vocal tics, which has many psychiatric comorbidities. Attention Deficit Hyperactivity Disorder (ADHD) is one of co-morbid features of this syndrome. The aim of this research is studying Tourette and co morbidity ADHD in school age children. One of our purposes is to identify the range of ADHD in Iranian Tourette patients.

Methods: Thirty children with Tourette syndrome attended in an adolescence psychiatry disorders clinic studied during one year using a descriptive, cross sectional method. Control group selected from students of Tehran schools matched to first group in age and sex. K-SADS questionnaire used to investigate the presence of ADHD in both groups. Results analyzed with SPSS.

Results: A clear pattern of co-morbidity was demonstrated with ADHD. Seventy percent of Tourette group had ADHD this co–morbidity in both sexes was different (20% of girls and 80% of boys).

Disussion: Although the frequency of ADHD co-morbidity with Tourette is high, but in our study was higher (50-60% versus 70%). Hence every Tourette patients must be studied for co–morbidity. Regarding to small size of studied people, similar studies must be performed with larger sample size.
