Brief Report: Differential Persistence of Primary Reflexes for Children with Autism Spectrum Disorder: A Systematic...

Area of Science:

• Neurodevelopmental Pediatrics
• Developmental Psychology
• Autism Spectrum Disorder Research

Background:

• Primary reflexes are automatic newborn movements.
• Understanding their persistence can offer insights into neurodevelopmental conditions.
• Autism Spectrum Disorder (ASD) is a complex neurodevelopmental condition.

Purpose of the Study:

• To investigate the prevalence of five primary reflexes in children with ASD.
• To identify variables predicting the persistence of these reflexes.
• To compare reflex presence in children with ASD, developmental disabilities, and typically developing children.

Main Methods:

• Assessed five primary reflexes (snout, visual rooting, sucking, tactile rooting, grasp).
• Analyzed reflex presence and persistence in three groups: ASD, developmental disability, and typically developing children.
• Matched typically developing children to ASD participants by chronological age.

Main Results:

• Children with ASD showed a higher prevalence of snout and visual rooting reflexes.
• Specific reflex patterns differed between the ASD group and controls.
• Persistence of certain reflexes was noted in the ASD cohort.

Conclusions:

• The persistence of primary reflexes may serve as a potential biomarker for Autism Spectrum Disorder (ASD).
• Further research is warranted to validate these findings for early ASD detection.
• This study highlights the link between early motor patterns and neurodevelopmental outcomes.
