What is Selective Mutism?

“Selective mutism” is a type of social anxiety disorder. Patients can talk to others as usual in familiar environments, but in certain environments (such as: schools/parties) they will not speak a word and become extremely nervous, even limbs stiff. The symptoms of each patient are unique, some do not speak at all, some speak in a low voice while some can express meaning with gestures or body movements.

According to the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), the diagnostic criteria for Selective Mutism are as follows:

《精神疾病診斷與統計手冊》第五版 (dsm-5)

Selective Mutism is a relatively rare disease. According to a survey in Finland, the incidence rate of this disease in junior primary school is 2%. There is a general lack of understanding of this disease in the public, and it is difficult for many children to obtain proper support.

Early intervention and treatment can effectively improve the situation for children who have the above symptoms or who have been diagnosed.
