Chronic motor tic disorder Causes and Risks:
The incidence of chronic motor or vocal tic disorder is greater than Tourette's Disorder. The incidence of this disorder range from 1 to 2%. It is, however, rare compared to the common short-lived childhood tic ( transient tic disorder ). Tics appear to get worse during emotional stress and are absent during sleep. The cause is unknown.
Prevention:
There is no known prevention for this condition. However, stimulants (such as methylphenidate or amphetamines) may hasten the appearance of tics or may make the tics worse in children with attention deficit disorder (ADD) .
Symptoms:
- vocalizations (grunts, abdominal ar diaphragmatic contractions)
- facial tics or other tics
- rapid, recurrent movement of the arms, legs, or other areas
Signs and Tests:
Diagnosis of a tic is generally made during physical examination . No tests are usually necessary
Treatment:
Treatment of chronic motor or vocal tic disorder depends on its severity, distress to the patient, and the effects the tics have on school or job performance. Psychotherapy and medication have been useful in treating this disorder.
Prognosis:
Prognosis for children who develop this disorder between the ages of 6 to 8 are good. Symptoms will last 4 to 6 years and then abate in early adolescence.
Complications:
There are usually no complications.
Call Your Healthcare Provider:
There is usually no need to see the health care provider for a tic unless it is severe or becomes 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.
