Selective mutism

Selective mutism is a mental disorder. Selective Mutism (SM) is the persistent refusal of a child to speak in some situations that require verbal communication (such as school, a stranger or crowded environment, etc.). A clinical syndrome characterized by normal speech on other occasions. Children often speak normally at home, but "refuse" to talk to teachers or classmates at school. Chinese people are more introverted, and children who do not speak when they start kindergarten or elementary school are often easily ignored by reasons such as introvertedness and shyness, which can cause children to fail to find and treat them in time. Onset usually occurs at the age of 3 to 5, and girls are more common. Because of anxiety or extreme shyness on certain occasions, patients are afraid to speak even if they can speak. As social pressure increases, social conflicts increase, social mobility increases, family problems and family conflicts increase, the factors that trigger SM increase. Not only do there exist children in China, there is also an increasing trend.
