What kind of doctor treats Selective Mutism?
A child psychologist or child psychiatrist, a mental health expert for children, often treats selective mutism. A speech and language therapist, a specialist in speech and communication, may also guide treatment. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What is selective mutism?
Selective mutism is an anxiety disorder. A person with it cannot speak in certain social situations, such as with classmates at school. The same person can speak freely with people they know well.
In most cases, the child is truly unable to speak in certain settings. It is not the same as mutism, where a person never speaks.
It usually starts during childhood. If it is not treated, it can continue into adulthood. It affects about 1 in 140 young children.
Symptoms
The main warning sign is a big difference in how a child talks with different people. A child may show a sudden stillness and a frozen face when expected to talk to someone outside their comfort zone. Other signs include:
- Being able to speak at home with family.
- Being unable to speak in certain social situations.
- Fear or anxiety around people they do not know well.
- Avoiding eye contact.
- Looking clingy, shy, or withdrawn.
- Looking stiff or tense.
Some children use gestures, such as nodding or shaking the head. More severely affected children tend to avoid any form of communication.
Some school-aged children avoid eating and drinking all day so they do not have to ask to leave the room. Without treatment, it can lead to isolation, low self-esteem, and social anxiety disorder.
Causes and who gets it
The cause is not always clear, but it is linked to anxiety. Most experts believe that affected children inherit a tendency to be anxious and inhibited, which means held back by fear. Some have a family history of selective mutism, extreme shyness, or anxiety disorders.
A speech and language disorder or a hearing problem can make speaking even more stressful. Selective mutism is not the same as autism, but a person can have both. It is more common in girls.
How doctors diagnose it
There is no test for selective mutism. The diagnosis is based on the person's history of symptoms. The pattern must be seen for at least 1 month, and the first month of school does not count.
Doctors also check that the problem is not better explained by another behavior, mental health, or communication disorder. A child who is learning a new language may not want to use it outside a familiar setting. This is not selective mutism.
A person may not be able to speak during the visit, and the clinician should be ready for this. The clinician may watch the child play or watch a video of the child speaking in a comfortable place.
Treatment
Treatment involves behavior changes, and the child's family and school should be involved. Treatment does not focus on the speaking itself. It focuses on lowering the anxiety linked to speaking.
It starts by removing pressure on the person to speak. The person then moves step by step, from relaxing in the setting to saying single words and sentences to one person. The final goal is speaking freely to all people in all settings.
Older children may need one-on-one support to lower their anxiety. Cognitive behavioral therapy (CBT) helps a person face fears through graded exposure. In graded exposure, the situations that cause the least anxiety are tackled first.
Medicine is only really appropriate for older children, teenagers, and adults whose anxiety has led to depression and other problems. It should never be used instead of behavior approaches.
When to see a doctor
Contact your child's health care provider if your child has symptoms of selective mutism and it is affecting school and social activities. Do not accept the opinion that your child will grow out of it. Without treatment, symptoms may get worse.
If you or someone you know is thinking about hurting yourself or others, call or text 988 (the Suicide and Crisis Lifeline) right away. You can also call 911 or go to the emergency room.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. Such a doctor can listen to your concerns and refer your child to a mental health professional or a speech and language therapist. They can also help the family and school stay on the same page.
Common questions
Is selective mutism just shyness?
No, selective mutism is an anxiety disorder and not simple shyness. A child with it does not choose to stay quiet. The child is truly unable to speak in certain settings.
Can adults have selective mutism?
Yes, selective mutism that is not treated can continue into adulthood. It is possible for adults to overcome it.
Can children overcome selective mutism?
Yes, with the right help most children can overcome selective mutism. The older a child is when it is diagnosed, the longer treatment will take.
How can I help my child at home?
Do not pressure or bribe your child to speak. Reassure your child that smiling and waving are fine until they feel better about talking. Do not praise your child in public for speaking, because this can cause embarrassment.
