Visual perception of ADHD children with sensory processing disorder.

Area of Science:

• Neuroscience
• Developmental Psychology
• Pediatrics

Background:

• Attention Deficit Hyperactivity Disorder (ADHD) is a common neurodevelopmental disorder.
• Sensory Processing Disorder (SPD) affects how individuals process sensory information.
• The interplay between ADHD, SPD, and visual perception in children requires further investigation.

Purpose of the Study:

• To compare visual perception between children with ADHD and those with ADHD and SPD.
• To explore the relationship between sensory processing and visual perception in children with ADHD.

Main Methods:

• 38 children aged 6-8 diagnosed with ADHD were divided into two groups: with and without SPD.
• Sensory processing was assessed using the Sensory Sensitivity Scale (SSP).
• Visual perception was evaluated using the Kaufman Assessment Battery for Children (K-DTVP-2).
• Statistical analyses included Spearman correlation and Mann-Whitney-U tests.

Main Results:

• Children with ADHD and comorbid SPD showed significantly lower visual perception scores compared to those with ADHD alone.
• General Visual Perception (GVP) scores correlated with Movement Sensitivity and Low Energy/Weakness sections of the SSP.
• Specific visual-perceptual quotients were negatively impacted by the presence of SPD.

Conclusions:

• Co-occurring SPD in children with ADHD is associated with diminished visual perception.
• Sensory processing, particularly vestibular and proprioceptive functions, appears related to visual perception in this population.
• Clinical interventions for children with ADHD should consider the impact of sensory processing deficits on visual perception and academic outcomes.
