Abstract

Gilles de la Tourette's syndrome (TS) is a neurobehavioral disorder of childhood onset that is characterized by motor and vocal tics and associated behavioral disturbances including obsessive-compulsive symptoms. We performed 30 channel quantitative electroencephalograms (EEGs) on 13 Tourette patients and 26 controls and studied both resting and manumotor/music perception activation conditions. Resting EEGs did not show any differences between patients and controls, as known from the literature. However, during simple and complex hand movements, as well as music perception tasks, there were subtle differences predominantly in alpha frequency. They suggested reduced brain activation during motor tasks in frontal and central regions, and on music perception in temporal and parietal regions, respectively. These findings may add evidence to the functional neuroanatomy of Tourette syndrome, affecting more areas than disturbed motor circuits.
