Hyperactivity is another very common symptom associated with Tourettes. Although Attention Deficit Hyperactivity Disorder is a completely separate condition from Tourettes, it frequently accompanies the disorder. ADHD is a condition where a person experiences habitual inattention and impulsive, hyperactive behavior that inhibits his or her development and daily life. This may present itself in several ways in the person’s life such as the inability to organize for completion of tasks, difficulty in listening, carelessness in school or work, the dislike of tasks that require long periods of concentration, and forgetfulness. A 2003 study published in the Journal of the American Academy of Child and Adolescent Psychiatry reported that nearly 65% of children with Tourettes also meet the diagnostic criteria for ADHD.Next
