Autistic spectrum disorder and learning disabilities are common in individuals with Möbius sequence, a brain-stem disorder. Early diagnosis and care are crucial for affected children, suggesting a link to early brain-stem damage.

Area of Science:

  • Neuroscience
  • Developmental Pediatrics
  • Genetics

Background:

  • Möbius sequence is a rare congenital disorder characterized by brain-stem dysfunction.
  • Autism spectrum disorder (ASD) and learning disabilities (LD) are complex neurodevelopmental conditions.
  • The co-occurrence of Möbius sequence with ASD and LD requires further investigation.

Purpose of the Study:

  • To determine the prevalence of autistic spectrum disorder in individuals with Möbius sequence.
  • To assess cognitive development and the incidence of learning disabilities in this population.
  • To explore potential etiological links between first-trimester brain-stem damage and ASD.

Main Methods:

  • A multidisciplinary study involving 25 individuals with Möbius sequence.

  • Comprehensive neuropsychiatric examinations, including standardized autism diagnostic interviews.
  • Cognitive development assessments were performed on 23 participants.

    • Main Results:

    • Ten out of 25 individuals (40%) were diagnosed with autistic spectrum disorder; six met full autism criteria.
    • Eight of 23 assessed patients (35%) exhibited learning disabilities.
    • Over one-third of participants presented with either ASD or LD, or both.

    Conclusions:

    • Autistic spectrum disorder and learning disabilities are frequently observed in individuals with Möbius sequence.
    • Awareness of this comorbidity is vital for accurate diagnosis and habilitation.
    • Findings support the hypothesis that first-trimester brain-stem damage may underlie a subset of ASD cases.
