Definition of Selective mutism
Selective mutism is a condition in which a child who can speak well stops speaking, usually in school or social settings.
Causes, incidence, and risk factors
The cause of selective mutism is unknown. Most experts believe that children with the condition inherit a tendency to be anxious and inhibited. Most children with this condition have some form of extreme social phobia.
Signs and tests
Teachers and counselors should consider cultural issues, such as recently moving to a new country and speaking another language. Children who are uncomfortable with a new language may not want to use it outside of a familiar setting. This is not necessarily selective mutism.
Current treatment involves behavior changes, family participation, and the child’s school. Certain medications that treat anxiety and social phobia have been used safely and successfully.
Children with this syndrome can have different outcomes. Some may need to continue therapy for shyness and social anxiety into the teenage years, and possibly into adulthood.
