Speech development and retention in Rett syndrome vary significantly. While many individuals lose speech, some retain words or phrases, with underlying brain differences noted.

Area of Science:

  • Neuroscience
  • Developmental Biology
  • Genetics

Background:

  • Rett syndrome is a rare genetic neurodevelopmental disorder.
  • Speech and language impairments are common in individuals with Rett syndrome.
  • Understanding speech development and retention is crucial for intervention.

Purpose of the Study:

  • To investigate speech development and retention patterns in a cohort of individuals with Rett syndrome.
  • To explore the neurobiological underpinnings of speech processing in Rett syndrome.
  • To describe the cognitive profile and coping strategies in adults with Rett syndrome and speech.

Main Methods:

  • Retrospective analysis of speech development in 265 individuals with Rett syndrome.
  • Morphological studies of speech area cytoarchitecture in 14 cases.

  • Comparison of cognitive profiles between 10 adults with Rett syndrome and speech and age-matched controls.

    • Main Results:

    • 30% never gained words, 55% lost words, 15% retained words, and 6% used phrases.
    • Morphological studies revealed interhemispheric differences in speech processing areas.
    • A consistent cognitive profile was observed across varying severity levels in adults with Rett syndrome.

    Conclusions:

    • Speech development in Rett syndrome is highly variable, with a significant proportion experiencing loss.
    • Interhemispheric differences in speech areas may contribute to speech processing variations.
    • Despite severity variations, a consistent cognitive profile exists, aiding in understanding and support.
