Tourette Syndrome (TS) or to be factually correct Gilles de la Tourette syndrome (George Gilles de la Tourette was the doctor who first recognised the symptoms) is a neurological condition of unknown origin, thought to be affecting one child in a hundred. It is characterised by tics, involuntary and uncontrollable sounds and movements. It is sometimes known as multiple tic disorder or tic spectrum disorder.
Tourette syndrome is also associated in the majority of cases with other behaviours, notably Obsessional Compulsive Disorder and Attention Deficit Disorder. Coprolalia (involuntary bad language), the most reknown but most misunderstood feature, affects only one person in ten.
TS starts in childhood. For about half of children with TS, the condition continues into adulthood is known to run in families, although some cases - known as sporadic Tourette syndrome - are not inherited. TS usually begins in childhood or the teenage years and is caused by problems with the development of the central nervous system. TS affects over three times more males than females.
