Tics

tics

Tics are movement disorders caracterized by a coordinated, repetitive movement involving one or more muscles.

Types

They are of two types depending on the pathology, namely

  • Motor tics: The condition in which motor movements are altered.
  • Vocal tics: Tics that involve sounds are called vocal tics.

These tics can either be simple or complex one. In case of simple motor tics there is involvement of only one muscle group and in case of simple vocal tics, the sound is not so distorted but meaning full. In case of complex motor tics, there is involvement of more than one muscle group and in complex vocal tics the sound is not meaning full.

There is a possibility that these may occur in any part of the body like hands, arms, shoulder and face. It has seemed that these tics result whenever there is feeling of fatigue, emotion, anxiety or excitement. Tics usually occur in the children.

Transient tics disorder: There is another variety of tics called transient tics disorder which occur for some period and then sets off.

Chronic Tic: Some tics remain there and could not go away. These are called chronic tics.

Signs and Symptoms

  • There may be repeated blinking of eye, wrinkling of nose, biting of lip, head twitching, shoulder shrugging, and kicking etc. These are motor tics signs.
  • The phonic or vocal tics signs and symptoms include clearing of throat, sniffing, hissing, barking coughing and grunting etc

Diagnosis

It is made after taking complete history and on physical examination. Test for various other diseases are done to role out the other disease like thyroid disease. So TSH levels are checked. MRI is done to see whether any abnormality present in the brain. Other chromosomal disorders are also checked to exclude them.

Treatment*

The treatment of tics includes education of the children about them plus certain therapies which are helpful in controlling. These include different trainings e.g.

Awareness Training: In this, they aim to make the children aware of the time during which they feel it. Ask them to see and notice them. It is for their self knowing about these tics.

Relaxation Training:  This targets muscle relaxation so that child remains free of stress and does not produce vocal tics as well as motor tics.

Competing Response Training: Here children are kept buy in those activities which are against the tics or by which tics may be stopped.

Management Training: Here a physician along with child evaluates about the tic condition whether they settle or progress.

These all trainings allow the children to cope up with their tics so that they do not feel embarrass about them and lose confidence. By performing these trainings, children get a confidence and better control on them.

Throughout a period family support is an essential component. They should encourage them and praise them for learning about tics and fighting with them.

Medical therapy is also done. Certain medicines are helpful like pimozide, resperidone and haloperidol. These drugs are neuroleptics and can lessen the conditions.
