Tourette syndrome (TS) is a condition that includes repetitive, involuntary sounds and movements called tics. It is a neurological condition that can affect children, adolescents and adults. Generally, the symptoms first appear in childhood and improve in the later teen years, but, in some cases they can continue into adulthood.
The estimates of the number of people in the US affected by Tourette syndrome vary widely, but several studies show that as many as 1% of children ages 5-18 are affected by TS. The tics associated with Tourette syndrome can change over time and vary in severity. In addition, TS is often associated with other conditions, including Attention Deficit/Hyperactivity Disorder, Obsessive-Compulsive Disorder, and anxiety.
