Tourette Syndrome is a chronic neurological disorder characterized by repeated involuntary movements and vocalizations called tics. There are significant associated conditions which compound the impact on patient's lives. Approximately 50-70% have Attention Disorder (ADD) or Attention Deficit Hyperactivity Disorder (ADHD). In addition, learning disabilities, obsessive compulsive behaviors, impulse control difficulties, sleep disorders, and mood disorders often accompany TS. It is not uncommon for an affected individual to have several, if not all, of these to some degree over the course of a lifetime. Clinical experience suggests that these associated conditions are more troublesome than the tics for the person with TS.
