The most common feature of selective mutism is when your child does not speak in social situations, including school, even though he can speak and understand spoken language. It used to be called elective mutism.
You may notice your child is overly shy when she enters preschool or kindergarten and seems unable to talk to others in the new class. You may have noticed that your child had a limited group of people she spoke to before starting school. Then, after your child is in school for several months, you find out that your child is not talking there.
Some characteristics of selective mutism are:
Many parents are confused by their children's inability to speak because their children are often very outgoing and animated at home. Some children will talk easily on the phone to people they are unable to talk to face-to-face.
The cause of selective mutism is not clear. Over the years, experts have suggested that an unpredictable environment might be a cause. Being a witness to a family conflict, experiencing a trauma before age 3, or being overly attached to one's mother may cause the mutism. More recently, researchers are suggesting that selective mutism is a sign of an anxiety disorder. Social phobia is an anxiety disorder in which people fear situations where they might say or do something embarrassing. People with this disorder often fear speaking in public or to strangers. People with social phobia often report being fearful of speaking when they were very young.
As children become older, there are fewer reports of selective mutism. This means that some children are able to begin speaking in public places without special help. Experts suggest that if the problem has lasted at least 6 months, parents should get professional help for their child.
Selective mutism is relatively rare. Your child's doctor should refer you to a therapist who knows about the disorder and has treated it before. It is important that the therapist get a very thorough medical, social, and psychological history from the child and family. Any treatment plan must involve the parents and include ways of dealing with this behavior at home.
It is also important to include teachers in the treatment plan. Many times teachers are unable to find out how much the child is learning. Often the treatment plan includes an educational in-service program for the teacher as well as specific recommendations for increasing the number of people your child will talk to.
Therapy
A number of treatments have been used by speech therapists, social workers, psychologists, and psychiatrists. The best results have come from behavioral therapy. Behavioral therapy is a treatment that helps families identify the problem and then plan a way to change it.
Many treatment plans begin by having the therapist watch your child through a one-way mirror while he plays with you. This is a good way to check if there are any problems with language development that are causing the mutism. If there are no language problems and your child acts normal, then the therapist "fades-in" slowly to become included in the family group. When your child is talking freely with the therapist, then the therapist can begin to help your child slowly expand the variety of people with whom she is able to talk. Often a reward system of some type is used as well.
Medication
In some recent cases in which anxiety was a problem, medication has been used along with behavioral therapy to help the child. This treatment should only be considered if the child has not responded to other therapy and is supervised by a pediatric psychiatrist familiar with the disorder.
