Tourette’s Syndrome: What is Tourette’s Syndrome?

This information was taken directly from the Centers for Disease Control and Prevention

Tourette Syndrome (TS) is a condition of the nervous system. TS causes people to have “tics”.

Tics are sudden twitches, movements, or sounds that people do repeatedly. People who have tics cannot stop their body from doing these things. For example, a person might keep blinking over and over again. Or, a person might make a grunting sound unwillingly.

Having tics is a little bit like having hiccups. Even though you might not want to hiccup, your body does it anyway. Sometimes people can stop themselves from doing a certain tic for awhile, but it’s hard. Eventually the person has to do the tic.

Types of Tics

There are two types of tics—motor and vocal:

Motor Tics

Motor tics are movements of the body. Examples of motor tics include blinking, shrugging the shoulders, or jerking an arm.

Vocal Tics

Vocal tics are sounds that a person makes with his or her voice. Examples of vocal tics include humming, clearing the throat, or yelling out a word or phrase. Tics can be either simple or complex:

Simple Tics

Simple tics involve just a few parts of the body. Examples of simple tics include squinting the eyes or sniffing.

Complex Tics

Complex tics usually involve several different parts of the body and can have a pattern. An example of a complex tic is bobbing the head while jerking an arm, and then jumping up.

Symptoms

The main symptoms of TS are tics. Symptoms usually begin when a child is 5 to 10 years of age. The first symptoms often are motor tics that occur in the head and neck area. Tics usually are worse during times that are stressful or exciting.

They tend to improve when a person is calm or focused on an activity. The types of tics and how often a person has tics changes a lot over time. Even though the symptoms might appear, disappear, and reappear, these conditions are considered chronic.

In most cases, tics decrease during adolescence and early adulthood, and sometimes disappear entirely. However, many people with TS experience tics into adulthood and, in some cases, tics can become worse during adulthood.1 Although the media often portray people with TS as involuntarily shouting out swear words (called coprolalia) or constantly repeating the words of other people (called echolalia), these symptoms are rare, and are not required for a diagnosis of TS.
