Tourette syndrome (TS) is an inherited, neurological disorder characterized by repeated involuntary movements and uncontrollable vocal (phonic) sounds called tics. In a few cases, such tics can include inappropriate words and phrases.
Although the basic cause of TS is unknown, current research suggests that there is an abnormality in the gene(s) affecting the brain's metabolism of neurotransmitters such as dopamine, serotonin, and norepinephrine. Neurotransmitters are chemicals in the brain that carry signals from one nerve cell to another.
Using new technology it is possible to diagnose whether or not a person will have Tourettes.
