Selective mutism (SM), formerly known as elective mutism, is a psychiatric disorder most commonly found in children. It is characterized by a persistent failure (for more than one month) to speak in select settings. Affected children understand spoken language and have the ability to speak. In most cases, affected children speak to their parents and a few selected others. In some cases, they do not speak to certain individuals in their household. The exact cause of this disorder is not known.
