Sensory processing patterns in developmental coordination disorder, attention deficit hyperactivity disorder and...

Area of Science:

• Neuroscience
• Developmental Psychology
• Pediatrics

Background:

• Sensory processing difficulties (SPD) are common in children with Developmental Coordination Disorder (DCD) and Attention Deficit and Hyperactivity Disorder (ADHD).
• Limited research exists on the variability of sensory processing within these specific pediatric populations.
• Understanding SPD is crucial for addressing developmental challenges in children.

Purpose of the Study:

• To investigate and compare sensory processing patterns in children with DCD, ADHD, and co-occurring symptoms against typically developing (TD) children.
• To examine the influence of social confounders on the relationship between DCD, ADHD, and SPD.
• To identify specific sensory processing differences associated with each condition.

Main Methods:

• A population-based sample of 452 children aged 6-12 years was recruited.
• Sensory processing patterns were assessed using the Short Sensory Profile-2.
• Multiple linear regression analyses were performed, controlling for social covariates.

Main Results:

• Children with DCD and ADHD symptoms demonstrated greater variability in atypical sensory processing compared to TD children.
• The DCD group showed higher prevalence of low registration and sensory sensibility issues.
• ADHD and co-occurring symptoms groups exhibited increased rates of low registration, sensory sensibility, and sensory seeking behaviors.

Conclusions:

• Significant variability in sensory processing exists among children with DCD, ADHD, and co-occurring symptoms.
• These findings underscore the complex relationship between neurological and social factors across these diagnoses.
• The study provides a foundation for better understanding and potentially intervening in SPD within these pediatric groups.
