Tourette Syndrome • Tourette Spectrum

Tourette syndrome — also called Tourette’s syndrome, Tourette Spectrum (TS), Tourette’s disorder, or Gilles de la Tourette syndrome is a neurological or neurochemical disorder characterized by tics: involuntary, rapid, sudden movements or vocalizations that occur repeatedly in the same way. Symptoms include multiple motor and one or more vocal tics present at some time during the disorder although not necessarily simultaneously; the occurrence of tics many times a day (usually in bouts) nearly every day or intermittently throughout a span of more than one year; the periodic change in the number, frequency, type and location of the tics, and in the waxing and waning of their severity; symptoms disappearing for weeks or months at a time; and onset before the age of 18.

Vocal tics may fall into various categories, including echolalia (the urge to repeat words spoken by someone else after being heard by the person with the disorder), palilalia (the urge to repeat one’s own previously spoken words), lexilalia (the urge to repeat words after reading them) and, most controversially, coprolalia (the spontaneous utterance of socially objectionable words, such as obscenities and racial or ethnic slurs). There are many other vocal tics besides those categorized by word repetition – in fact, a TS tic can be almost any possible short vocal sound, with the most common tics resembling throat clearing, short coughs, grunts, or moans. Motor tics can be of endless variety and may include hand-clapping, banging the knuckles together, and contorted facial grimacing.

Other commonly associated disorders are obsessive-compulsive disorder (OCD) and attention deficit hyperactivity disorder (ADHD).

According to the DSM-IV, TS is indicated when a person exhibits both multiple motor and one or more vocal tics (although these do not need to be concurrent) over the period of 1 year, with no more than 3 consecutive tic-free months. This disturbance must cause distress or impairment in the individual’s normal functioning. The onset must have been before the age of 18, and cannot be attributed to the use of a substance or another medical condition.

It is estimated that as many as 1 in 200 experience some form of TS. Males are affected 3 to 4 times more often than females. Some cases decrease in severity or cease entirely upon reaching adulthood.

As it is a spectrum disorder, the severity of the condition can range vastly. Those with mild cases are often highly functioning, so much so that others would not know of their condition. More severe cases can inhibit or prevent the individual from engaging in common activities such as holding a job, having a fulfilling social life, or maintaining his/her basic needs.
