Selective Mutism (SM)

Selective Mutism in Children 

Selective Mutism (SM) is an anxiety-related behavioral disorder in which a child consistently fails to speak in certain situations (typically at school), despite speaking normally in others. This inability to speak leads to significant impairment in academic and/or social functioning. Most, but not all, children with SM also show additional symptoms of social anxiety that are not specifically related to speaking. The onset of SM is usually early, often becoming noticeable when children enter school (around ages 4–5). Cognitive behavior therapy (CBT), particularly approaches focused on gradual exposure to speaking, and/or SSRI medication are considered the most effective treatments for Selective Mutism.
