What is Tourette syndrome?

Tourette syndrome, rare inherited neurological disorder characterized by recurrent motor and phonic tics (involuntary muscle spasms and vocalizations). It is three times more prevalent in males than in females. Although the cause of Tourette syndrome is unknown, evidence suggests that there may be an abnormality of one or more chemical neurotransmitters in the brain. It is named for Georges Gilles de la Tourette, who first described the disorder in 1885. The English author Samuel Johnson may have suffered from a form of the disorder, based on contemporary descriptions of his facial tics and of the strange vocalizations interrupting his normal speech.
