Classification of Children With Autism Spectrum Disorder by Sensory Subtype: A Case for Sensory-Based Phenotypes / Alison E. LANE in Autism Research, 7-3 (June 2014)
[article]
Titre : Classification of Children With Autism Spectrum Disorder by Sensory Subtype: A Case for Sensory-Based Phenotypes Type de document : Texte imprimé et/ou numérique Auteurs : Alison E. LANE, Auteur ; Cynthia A. MOLLOY, Auteur ; Somer L. BISHOP, Auteur Article en page(s) : p.322-333 Langues : Anglais (eng) Mots-clés : sensory autism phenotypes subtypes children classification model-based cluster analysis Short Sensory Profile Index. décimale : PER Périodiques Résumé : This study examines whether sensory differences can be used to classify meaningful subgroups of children with autism spectrum disorder (ASD). Caregivers of children with ASD aged 2–10 years (n?=?228) completed the Short Sensory Profile. Model-based cluster analysis was used to extract sensory subtypes. The relationship of these subtypes to age, gender, autism symptom severity, and nonverbal intelligence quotient (IQ) was further explored. Four distinct sensory subtypes were identified: (a) sensory adaptive; (b) taste smell sensitive; (c) postural inattentive; and (d) generalized sensory difference. The sensory subtypes differ from each other on two dimensions: (a) the severity of reported sensory differences; and (b) the focus of differences across auditory, taste, smell, vestibular and proprioceptive domains. Examination of the clinical features of each subtype reveals two possible mechanisms of sensory disturbance in autism: (a) sensory hyperreactivity; and (b) difficulties with multisensory processing. Further, the sensory subtypes are not well explained by other variables such as age, gender, IQ, and autism symptom severity. We conclude that classification of children using sensory differences offers a promising method by which to identify phenotypes in ASD. Sensory-based phenotypes may be useful in identifying behavioral features responsive to specific interventions thereby improving intervention effectiveness. Further validation of the sensory-based phenotypes by establishing neural and physiological correlates is recommended.

Titre : Brief Report: Further Evidence of Sensory Subtypes in Autism Type de document : Texte imprimé et/ou numérique Auteurs : Alison E. LANE, Auteur ; Simon J. DENNIS, Auteur ; Maureen E. GERAGHTY, Auteur Année de publication : 2011 Langues : Anglais (eng) Mots-clés : Sensory processing Subtypes Autism Model-based cluster analysis Index. décimale : PER Périodiques Résumé : Distinct sensory processing (SP) subtypes in autism have been reported previously. This study sought to replicate the previous findings in an independent sample of thirty children diagnosed with an Autism Spectrum Disorder. Model-based cluster analysis of parent-reported sensory functioning (measured using the Short Sensory Profile) confirmed the triad of sensory subtypes reported earlier. Subtypes were differentiated from each other based on degree of SP dysfunction, taste/smell sensitivity and vestibular/proprioceptive processing. Further elucidation of two of the subtypes was also achieved in this study. Children with a primary pattern of sensory-based inattention could be further described as sensory seekers or non-seekers. Children with a primary pattern of vestibular/proprioceptive dysfunction were also differentiated on movement and tactile sensitivity.
