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