Swallowing difficulties in children with Down syndrome may stem from oral hypersensitivity and disordered pharyngeal phases. Silent aspiration, often undetected, is a key factor in respiratory illnesses for this population.

Area of Science:

  • Pediatric Medicine
  • Speech-Language Pathology
  • Genetics

Background:

  • Down syndrome is associated with various health complications, including feeding and swallowing issues.
  • Oral hypersensitivity can affect food acceptance and oral phase function.
  • Pharyngeal phase dysfunction and aspiration are potential risks in children with Down syndrome.

Purpose of the Study:

  • To investigate the swallowing behavior in children with Down syndrome.
  • To identify the impact of oral hypersensitivity on the oral phase of swallowing.
  • To assess the prevalence and characteristics of pharyngeal phase disorders and aspiration.

Main Methods:

  • Review of swallowing behavior in 19 children with Down syndrome.
  • Assessment of oral phase function, considering oral hypersensitivity.

  • Identification of pharyngeal phase disorders and aspiration events.

    • Main Results:

    • Oral hypersensitivity may impact the oral phase and acceptance of textured foods.
    • A disordered pharyngeal phase was observed in 16 out of 19 children.
    • Aspiration occurred in 10 children, with 8 experiencing silent aspiration.
    • Silent aspiration did not correlate with oral phase severity.

    Conclusions:

    • Oral hypersensitivity can significantly affect the oral phase of swallowing in children with Down syndrome.
    • Pharyngeal phase dysfunction and aspiration are prevalent, with silent aspiration being a significant concern.
    • Aspiration should be considered a contributing factor to the high incidence of respiratory illnesses in this population.
