They can be stopped voluntarily for brief periods. Sounds that are made involuntarily are called vocal tics. Most tics are mild and hardly noticeable. However, in some cases they are frequent and severe and can affect many areas of a child's life. Children with Tourette's disorder have both body and vocal tics.
Some tics disappear by early adulthood and some continue.
Children with Tourette's disorder may have problems with attention and concentration. They may act impulsively or they may develop obsessions and compulsions. Sometimes people with Tourette's disorder may blurt out obscene words, insult people, or make obscene gestures or movements. They cannot control these sounds and movements, and they should not be blamed for them. Punishment by parents, teasing by classmates, and scolding by teachers will not help the child to control the tics but will hurt the child's self-esteem.
