Comparison of the Sensory Profile Among Autistic Individuals and Individuals with Williams Syndrome.

This study compared how autistic children and children with Williams syndrome process sensory information differently. Researchers found that both groups had similar overall sensory challenges, but there was one key difference: autistic children were more sensitive to sensory input. The study also showed that as children got older, their sensory needs changed differently depending on their condition. This helps us understand that while autistic children share some sensory experiences with other neurodivergent children, they also have unique patterns.

This comparative study examined sensory processing differences between autistic individuals (n=39, ages 4.2-14.0 years) and individuals with Williams syndrome (n=60, ages 3.4-19.8 years) using caregiver-completed Sensory Profile questionnaires. Results revealed significant between-group differences only in Sensory Sensitivity, while Low Registration, Sensation Seeking, and Sensation Avoiding scores were similar. Developmental patterns differed across conditions: both groups showed decreasing Sensation Seeking with age, but Sensory Sensitivity decreased with age only in autism, while Sensation Avoiding increased with age only in Williams syndrome. Low Registration remained stable across development in both groups.

The findings highlight both similarities and distinct developmental trajectories in sensory processing between these neurodevelopmental conditions.

Results suggest that while autistic individuals share some sensory processing similarities with other neurodevelopmental conditions, they demonstrate unique sensory sensitivity patterns. Age-related improvements in sensory sensitivity for autistic individuals indicate potential for targeted early interventions. Clinicians should consider both shared and condition-specific sensory profiles when developing treatment plans.

Small sample sizes (autism n=39, Williams syndrome n=60) limit generalizability. Reliance on caregiver reports may introduce bias. Cross-sectional design prevents definitive conclusions about developmental trajectories. Age ranges differed between groups, potentially confounding developmental comparisons.

With the current study, we aimed to reveal the similarities and differences in sensory profiles between Williams syndrome (WS) and autism spectrum disorder. Using the sensory profile questionnaire completed by the caregivers, we analyzed the WS (n = 60, 3.4-19.8 years) and autistic (n = 39, 4.2-14.0 years) groups. The Severity Analysis revealed a significant group difference in Sensory Sensitivity but not in Low Registration, Sensation Seeking, and Sensation Avoiding subscales. Age can modulate the subscale scores differently across groups.

For Sensation Seeking, the scores of both groups decreased with development. However, the scores of Sensory Sensitivity decreased with age in the autistic group but not in the WS group. Sensation Avoiding scores increased with development in the WS group but not in the autistic group. No significant developmental changes were observed in Low Registration.

This study highlights the cross-syndrome similarities and differences in sensory profiles and developmental changes in autistic individuals and individuals with WS.
