Tic - transient tic disorder
Causes, incidence, and risk factors
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.
The child may have facial tics or tics involving movement of the arms, legs, or other areas.
Tics may involve:
Movements that occur again and again and don't have a rhythm
An overwhelming urge to make the movement
Brief and jerky movements that include the following:
Clenching the fists
Curling the toes
Flaring the nostrils
Jerking the arms
Opening the mouth
Raising the eyebrows
Shrugging the shoulders
Sticking out the tongue
The tics often look like nervous behavior. Tics appear to get worse with stress and do not occur during sleep.
Sounds may also occur, such as:
Signs and tests
The health care provider should 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.
Other disorders such as anxiety, attention deficit disorder, myoclonus, obsessive-compulsive disorder, epilepsy, and focal dystonia, may need to be ruled out.
Health care providers recommend that family members do NOT call attention to the tics at first, because unwanted attention may make the tics worse. If tics are severe enough to cause problems in school or work, behavioral techniques and medications may help.
Simple childhood tics usually disappear over a period of months.
Talk to your health care provider if you are concerned about a transient tic disorder, especially if it continues or disrupts your child's life. If you are not sure whether the movements are a tic or a seizure, call your health care provider right away.
