What is Tourettes syndrome'
Tourette Syndrome (TS) is a neurological disorder characterized by tics. According to Bruun, Cohen, and Leckman (1984), tics are involuntary, repetitive, and stereotyped movements of individual muscle groups.

People with this disorder may have outbursts that are not intentional. Symptoms usually appear before the age of 18. Greene (2002), reported, Tourettes syndrome is named for Georges Gilles de la Tourette who first described the condition in 1885. Tics (involuntary, nonrhythmic movements) are the hallmark of the disease. Symptoms can sometimes disappear for weeks or months and come back.

These changes are influenced by genetics, by neurobiology, and by what is going on in the childs life. Tourette Syndrome Association, Inc. (2000-2002) says, Most people with TS lead productive lives and participate in all professions.
