What Causes Chronic motor or vocal tic disorder:
It is a variety of tic disorder in which there is or had multiple motor tics and one or more vocal tics that occur not at the same time. Almost always is marked the beginning in childhood or adolescence. It is characterized by the development of motor tics in front of the voice. Symptoms often worsens during adolescence, is characterized by preservation of elements of disorder in adulthood.
Much like an important role play the genetic factors and disorders of neurochemical functions of the central nervous system.
The combination of chronic motor or vocal tics occur in 1.6% of the population.
What are the symptoms
Vocal tic disorder is characterized by motor or vocal tics but not at the same time. Tics occur many times a day, nearly every day or intermittently for more than one year. Beginning is at the age of 18. Tics occur not only during intoxication or substance abuse as a result of certain CNS diseases (ex Huntington’s disease, viral encephalitis). Types of users and their localization are similar to the transient. Chronic vocal tics are less common than chronic motor ones. Voice tics are often loud and strong, made up of noise generated by the reduction of the larynx, abdomen, diaphragm. Rarely they are multiple with explosive, repetitive vocalizations, coughing, grunting. As with motor tics, vocal tics can be suppressed spontaneously for a while, disappear during sleep and grow under the influence of stress factors. Prognosis is somewhat better in children who get at the age of 6-8 years. If tics include limb or trunk, and not just the face, the prognosis is usually worse.
Diagnosis of chronic motor or vocal tic disorder
It is also necessary in case of tremor, mannerisms, stereotypes, or disorders in the form of bad habits (the slopes of the head, body rocking), usually occurring in childhood autism or mental retardation. Arbitrary nature of stereotypes and bad habits, lack of subjective distress over disorder distinguishes them from ticks. Treatment of hyperactivity with attention deficit psychostimulants enhances the existing tics or accelerates the development of new ticks. However, in most cases after drug withdrawal tics terminate or return to the level that existed before treatment.
How to treat chronic motor or vocal tic disorder
It depends on the severity and frequency of tics, subjective experiences of secondary violations in the school and the presence of other related psychotic disorders.
Psychotherapy plays the main role in the treatment..
Minor tranquilizers are ineffective. In some cases, haloperidol is effective, but should consider the risk of side effects of this drug, including the development of tardive dyskinesia.
