Abstract
We sought to determine whether Tourette syndrome (TS) was related to attent ional disturbance independent of Attention Deficit Hyperactivity disorder ( ADHD) and obsessive-compulsive symptoms (OCS), two comorbid conditions asso ciated with attentional problems in other populations. Participants were 74 children [21 with uncomplicated TS (TS-Only), 14 with TS and ADHD (TS-ADHD ), 21 with ADHD, and 18 controls]. Impaired sustained attention and impulsi vity on a Continuous Performance Task were uncommon in the TS-Only group, b ut common in TS-ADHD and ADHD. The TS-ADHD group was less impulsive than th e ADHD group, but had a higher rate of whole-body ties than the TS-Only gro up, raising questions about the diagnosis of ADHD in TS. OCS was not an ind ependent risk factor for attention problems. However, the association of ti c severity and impulsivity was consistent with the theory that TS involves dysfunction in cortical-subcortical circuits mediating behavioral inhibitio n.
