Tourette Syndrome And ADHD Frequently Occur Together

ScienceDaily (Apr. 20, 2009) — The most disabling aspect of Tourette syndrome is that in 90% of cases, it exists in conjunction with another disorder. The most frequent co-occurring condition in people with Tourette is attention deficit hyperactivity disorder (ADHD), though the cause of this association is uncertain. Having one disorder can be disabling enough, but having two means coping with more than twice the disability.
