How many children have Tourette's

Nearly 150,000 children in the U.S. could have Tourette's syndrome. Researchers from the Centers for Disease Control and Prevention looked at data from the 2007 National Survey of Children's Health which covered 64,034 people between 6 and 17. They found that 3 in 1,000 children had Tourette's which is characterized by sometimes debilitating tics such as repetitive, stereotypical movement and inappropriate vocalizations. The syndrome is linked to higher rates of attention-deficit hyperactivity disorder (ADHD) and obsessive-compulsive disorder (OCD) and can cause learning disabilities and problems getting on with other children.
