Tourette syndrome Definition
Caracteristics of the symptoms
Tourette syndrome – TS
Tourette Syndrome (TS) is a neurological disorder characterized by tics (rapid and sudden, recurrent, stereotyped motor movements or vocalizations that are involuntary).
Both multiple motor and one or more vocal tics can be present at some time during active phases of TS, not necessarily at the same time.
Tics can occur many times a day (usually in series) almost every day or intermittently over a period of more than one year.
We can observe a variation in the number, frequency, type, localization and intensity of tics.
Symptoms appear before age 18.
Tics are not caused by a substance (stimulant) or other medical condition.
The number, localization, frequency and severity of tics can change over time.
Vocal tics are noises, words or sounds.
Speaking obscenities can be found in less than 10% of people with TS.
Tics may diminish during adolescence and adulthood and disappear completely in certain cases.
Even when remission is complete, certain tics can reappear during stressful periods.
