Transient tic disorder is characterized by single or multiple motor tics, which are brief, repetitive, difficult-to-control movements and/or vocalizations that often resemble nervous mannerisms. To meet the criteria for this condition, these tics must have occurred almost every day for at least 4 weeks, but not have been present for more than a year.

Alternative Names

Tic - transient tic disorder

Causes, incidence, and risk factors

Transient (short-lived, temporary) tic disorder is common in children: 5% to 24% of all school-age children have had tics. The cause of transient tic disorder can be physical or psychological. It may be a mild variant of Tourette's syndrome. The child may have facial tics or tics involving movement of the arms, legs, or other areas. Tics appear to get worse with emotional stress and do not occur during sleep.

Signs and tests

Physical causes of transient tic disorder should be considered before a diagnosis is made.

Treatment

Clinicians recommend the family pay no attention to the tics at first, since unwanted attention may make the tics worse. If tics are severe enough to cause problems in school or work, behavioral techniques are recommended and medications may be considered.

Expectations (prognosis)

Simple childhood tics usually disappear over a period of months.

Complications

There are usually no complications. A chronic motor or vocal tic disorder can develop.

Calling your health care provider

Consult with your health care provider if you are concerned about a transient tic disorder, particularly if it becomes persistent or disruptive to the child's life. If there is a question whether the movements are really a tic (as opposed to a seizure , for example), consult with your health care provider immediately.
