Elective mutism (EM) may be linked to developmental delays. This study suggests developmental disorders could predispose children to selective speech refusal in specific situations.

Area of Science:

  • Child and Adolescent Psychiatry
  • Developmental Psychology

Background:

  • Elective mutism (EM) is defined in ICD-10 as a situational lack of speech in children with adequate language ability.
  • Previous diagnostic systems, like ICD-9, did not recognize EM as a distinct category.
  • The diagnosis of EM excludes pervasive and specific developmental disorders of speech and language.

Purpose of the Study:

  • To investigate the association between elective mutism and developmental disorders/delays.
  • To determine the extent to which EM is reported alongside developmental conditions in existing literature.

Main Methods:

  • Presentation of two case studies of children referred for EM with co-occurring developmental delays.
  • Literature search across four databases using the keyword "mutism" to inventory related studies.

  • Assessment of patients for developmental delays and cognitive function.

    • Main Results:

    • Both case studies presented with specific developmental delays; one child exhibited mild intellectual disability.
    • The literature search indicated that "mutism" is often discussed in contexts that may include developmental issues.
    • Findings suggest a potential link between EM and underlying developmental challenges.

    Conclusions:

    • Elective mutism may be associated with developmental disorder or delay.
    • Developmental delays could be a predisposing factor for the development of elective mutism.
    • Further research is warranted to explore the relationship between EM and developmental conditions.
