Sensory hypo-responsiveness or hyper-responsiveness was considered in DSM-III as infantile autism-associated features, while DSM-III-R and DSM-IV did not include sensory abnormalities as definite diagnostic criteria. This increase is hypothesized partly due to changes in the understanding of the disorder and diagnostic methods, and partly due to an actual increase in ASD. Meanwhile, in the USA, prevalence of ASD (among children aged 8 years) has increased from one in 150 children during 2000–2002 to one in 68 during 2010–2012, reaching 1 in 59 children in the 2014 survey. The prevalence of ASD among the developmentally disabled children in Egypt was estimated to be 33.6%. Worldwide prevalence is 1–2% of the population with an average male to female ratio of 4–5:1. Early ASD screening is mandatory in families with parental consanguinity.Īutism spectrum disorder (ASD) is one of the most common neurodevelopmental disorders. SPD negatively affected the ASD symptom triad which highlights the importance of sensory integration therapy (SIT) as a major core of ASD treatment alongside the other treatment modalities. Finally, there was high percentage of parental consanguinity among the participants (80%). There was a high significant negative correlation between the severity of autistic symptoms (assessed by CARS) and the SSP total scores, and for all subscales ( p ˂ 0.001) except for low energy/weak, the correlation was significant (not highly significant) ( p ˂ 0.05). As regards communication deficits, the ADI-R (B), there was significant negative correlation with the SSP total scores and the auditory filtering held the highest negative correlation ( p ˂ 0.008), and as regards stereotypic behavior, the ADI-R (C), there was significant negative correlation with the SSP total scores and all subscales except for low energy/weak and visual/auditory sensitivity whereas taste/smell sensitivity and auditory filtering held the highest negative correlation ( p ˂ 0.001). As regards social interaction, the ADI-R (A), there was significant negative correlation with the SSP total scores and all subscales except for low energy/weak and visual/auditory sensitivity, whereas under-responsive/seeks sensation held the highest negative correlation ( p ˂ 0.008).

There was a significant negative correlation between SPD (assessed by short sensory profile: SSP) and symptom triad in ASD. To our knowledge, this issue was not studied before in Egyptian literature. The purpose of this study is to determine the relation between SPD and the symptom triad in ASD namely social interaction, communication deficits, and stereotypic behavior. In DSM-IV, the diagnostic criteria of autism consisted of three domains: impairment in social interaction, communication deficits, and stereotypic behavior, while in DSM-5 they were condensed into two domains: social communication deficits and restricted patterns of behavior to which sensory processing deficits (SPD) were added, manifested by hypo- or hyper-reactivity to sensory stimuli or uncommon interests in sensory aspects of the surrounding environment.

Autism spectrum disorder (ASD) is one of the most common neurodevelopmental disorders.
