Consonants in Cri du chat syndrome: a case study

Area of Science:

• Speech-language pathology
• Genetics
• Developmental psychology

Background:

• Cri du chat syndrome is a genetic disorder associated with developmental delays.
• Articulation disorders are common in children with genetic syndromes.
• Understanding speech sound development in rare genetic conditions is crucial for early intervention.

Observation:

• A longitudinal case study observed consonant productions in a Norwegian girl with Cri du chat syndrome from age 4 to 9.
• The study documented articulation errors including differentiation, coordination, sequencing, and omissions.
• Segmental omissions were frequently noted throughout the observation period.

Findings:

• The girl exhibited both delayed and deviant consonant productions compared to typically developing children.
• Articulation errors decreased in frequency and severity as the child aged.
• Improved accuracy in word production was observed over the study period.

Implications:

• Case studies like this provide valuable insights into the speech development trajectory of individuals with Cri du chat syndrome.
• Findings can inform targeted speech therapy interventions for children with similar genetic conditions.
• Longitudinal data highlights the potential for speech development and improvement in individuals with rare genetic disorders.
