Tourette Syndrome

Tourette Syndrome (also called Tourette’s Syndrome, Tourette’s Disorder, Gilles de la Tourette Syndrome, GTS or, more commonly, simply Tourette’s or TS) is an inherited neuropsychiatric disorder with onset in childhood, characterized by multiple physical (motor) tics and at least one vocal (phonic) tic. These tics characteristically wax and wane, can be suppressed temporarily, and are preceded by a premonitory urge. Tourette’s is defined as part of a spectrum of tic disorders, which includes provisional, transient and persistent (chronic) tics.

Tourette’s was once considered a rare and bizarre syndrome, most often associated with the exclamation of obscene words or socially inappropriate and derogatory remarks (coprolalia), but this symptom is present in only a small minority of people with Tourette’s. Tourette’s is no longer considered to be as rare as it was thought to be, but it is not always correctly identified because most cases are mild and the severity of tics decreases for most children as they pass through adolescence. Between 0.4% and 3.8% of children ages 5 to 18 may have Tourette’s; the prevalence of other tic disorders in school-age children is higher, with the more common tics of eye blinking, coughing, throat clearing, sniffing, and facial movements. Extreme Tourette’s in adulthood is a rarity, and Tourette’s does not adversely affect intelligence or life expectancy.
