Selective mutism is a complex anxiety disorder primarily seen in children, where they consistently fail to speak in specific social situations, such as at school or with playmates, despite speaking in other settings, like at home. This condition can hinder a child's ability to communicate and interact with peers, impacting their social development and academic performance. The exact cause of selective mutism is not fully understood, but it is often linked to extreme shyness, social anxiety, or a traumatic event. Early intervention, including therapy and support from parents and teachers, can help children overcome this challenge and improve their communication skills.
