P 46 Tourette syndrome and attention deficit hyperactivity disorders

Abstract

Background Tourette syndrome (TS) and related tic disorders are commonly associated with obsessive-compulsive disorder (OCD) and attention deficit hyperactivity disorder (ADHD). It has been argued, however, that any observed association between TS and these and other psychopathologies may be due to ascertainment bias in that individuals with multiple problems are more likely to be referred for medical evaluation. A tic is a sudden, uncontrollable movement which can occur anywhere in the body or be vocal. Tics are often very mild and may not be noticeable to others but tics can also be grandiose. It is common for some tics to normally occur in people, particularly children. Methods In order to overcome the potential confounding by ascertainment bias, we conducted a community-based study of school children using direct interviews to determine the prevalence of tic disorders and any comorbid psychopathology. A standard psychiatric interview and standardized rating scales were utilized to diagnose childhood behavioral disorders. Results Of the 325 children interviewed, 71 were identified as having tics. The following psychopathologies were found more commonly (p Conclusion The behavioral spectrum of tic disorders includes OCD, other anxiety disorders, a mood disorder, and attention-deficit and disruptive behavior disorders.
