Selective Mutism

Medically reviewed · Ratel Health editorial team · Sunday, 16 August 2026

A childhood anxiety condition involving consistent failure to speak in specific social situations despite speaking normally in others.

Overview

Selective mutism involves consistent failure to speak in specific social situations, such as school, despite speaking in other situations, such as at home, persisting for at least one month.

Signs and Symptoms

Symptoms can include silence in specific settings, interference with academic or social functioning, and underlying social anxiety. Experiencing one or more of these symptoms does not necessarily mean that a person has this condition. Diagnosis requires an appropriate clinical evaluation.

Causes and Risk Factors

The exact cause is not fully understood. Anxiety proneness and temperamental behavioral inhibition are associated with increased risk.

Diagnosis

A diagnosis should be made by a qualified healthcare professional following a comprehensive clinical assessment. Clinicians may use established diagnostic frameworks such as DSM-5-TR and/or ICD-11 as part of a comprehensive assessment.

Treatment

Treatment depends on the individual’s symptoms, clinical history, severity, age, co-occurring conditions, and other relevant factors.

Psychotherapy

Behavioral therapy, often incorporating gradual exposure, has evidence supporting its use for selective mutism.

Living With Selective Mutism

Coordination between home and school on consistent, low-pressure communication strategies can support progress.

When to Seek Professional Help

Professional evaluation may be appropriate if symptoms persist, worsen, cause significant distress, or interfere with work, school, or relationships.

Emergency Situations

If a person may be in immediate danger, is experiencing a medical or psychiatric emergency, or may harm themselves or another person, seek immediate assistance through appropriate local emergency services.

Outlook

Many children improve significantly with early, consistent behavioral intervention.
