Transient tic disorderTic - transient tic disorder
Transient tic disorder is a condition in which a person makes 1 or many brief, repeated, movements or noises (tics). These movements or noises are involuntary (not on purpose).
Transient tic disorder is common in children.
The cause of transient tic disorder can be physical or mental (psychological). It may be a mild form of Tourette syndrome .
Tourette syndrome is a condition that causes a person to make repeated, quick movements or sounds that they cannot control.
The child may have facial tics or tics involving movement of the arms, legs, or other areas.
A facial tic is a repeated spasm, often involving the eyes and muscles of the face.
Tics may involve:
- Movements that occur again and again and do not have a rhythm
- An overwhelming urge to make the movement
- Brief and jerky movements that include blinking, clenching the fists, jerking the arms, kicking, raising the eyebrows, sticking out the tongue.
The tics often look like nervous behavior. Tics appear to get worse with stress. They do not occur during sleep.
Sounds may also occur, such as:
- Throat clearing
Exams and Tests
The health care provider will consider physical causes of transient tic disorder before making a diagnosis.
In order to be diagnosed with transient tic disorder, the child must have had tics almost every day for at least 4 weeks, but less than a year.

Doctors recommend that family members do not call attention to the tics at first. This is because unwanted attention may make the tics worse. If the tics are severe enough to cause problems at school or work, behavioral techniques and medicines may help.
Simple childhood tics usually disappear over a period of months.
There are usually no complications. A chronic motor tic disorder can develop.
Chronic motor tic disorder
Chronic motor tic disorder is a condition that involves quick, uncontrollable movements or vocal outbursts (but not both).
