Barking Up the Wrong Tree-Motor-Sensory Elements as Prodrome in Autism

Area of Science:

• Neuroscience
• Developmental Psychology
• Pediatrics

Background:

• Autism spectrum disorder (ASD) diagnosis and intervention are often delayed due to reliance on social and communication behaviors observable after 18 months.
• The rising prevalence of ASD (1:36 children) necessitates earlier diagnostic and intervention strategies.
• The precise origins of ASD remain largely unknown despite extensive research.

Purpose of the Study:

• To explore motor difficulties and proprioceptive interoception deficits as potential early indicators (prodrome) of ASD.
• To investigate the potential of sensory-motor challenges for enabling earlier diagnosis and intervention in ASD.
• To propose a novel perspective on ASD assessment and intervention in infancy.

Main Methods:

• Review and analysis of existing research on sensory-motor development in relation to ASD.
• Exploration of proprioceptive interoception and motor control as potential early markers.
• Conceptual framework development for early identification and intervention strategies.

Main Results:

• Sensory-motor difficulties, including issues with proprioception, may precede the emergence of typical ASD social and communication traits.
• These early sensory-motor signs could serve as crucial indicators for timely ASD diagnosis.
• Focusing on these prodromal signs offers a new pathway for infant assessment and intervention.

Conclusions:

• Motor and proprioceptive interoception challenges represent a promising avenue for the early detection of ASD.
• Early identification through sensory-motor assessments can facilitate timely intervention, potentially improving long-term outcomes for children with ASD and their families.
• This approach may shift the paradigm for viewing and managing ASD, starting from infancy.
