Behavioral Phenotype of ASD Preschoolers with Gastrointestinal Symptoms or Food Selectivity / M. PROSPERI in Journal of Autism and Developmental Disorders, 47-11 (November 2017)

Titre : Behavioral Phenotype of ASD Preschoolers with Gastrointestinal Symptoms or Food Selectivity Type de document : Texte imprimé et/ou numérique Auteurs : M. PROSPERI, Auteur ; E. SANTOCCHI, Auteur ; Giulia BALBONI, Auteur ; A. NARZISI, Auteur ; M. BOZZA, Auteur ; F. FULCERI, Auteur ; Fabio APICELLA, Auteur ; R. IGLIOZZI, Auteur ; A. COSENZA, Auteur ; Raffaella TANCREDI, Auteur ; Sara CALDERONI, Auteur ; F. MURATORI, Auteur Article en page(s) : p.3574-3588 Langues : Anglais (eng) Mots-clés : Anxiety Problems Child Behavior Checklist 1(1/2)-5 Externalizing Problems Restrictive and repetitive behaviours Sleep Problems Young Children Index. décimale : PER Périodiques Résumé : This study investigated the prevalence and type of gastrointestinal (GI) and food selectivity (FS) symptoms in 163 preschoolers with ASD, and their possible links with core ASD features and emotional/behavioural problems. 40.5% of children with ASD had at least one severe GI symptom or FS. Preschoolers with and without GI symptoms and with and without FS were significantly different on several emotional/behavioural problems and restrictive/repetitive behaviours, whereas they did not differ significantly on performance IQ and autistic severity. The GI plus FS group presented with Sleep Problems, Self-injurious Behaviors and Anxiety Problems. Results indicated the need for early identification of GI disturbances and FS in order to design tailored intervention for these symptoms frequently associated to challenging behaviours in ASD.

Titre : Exploring sensory phenotypes in autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : N. E. SCHEERER, Auteur ; K. CURCIN, Auteur ; B. STOJANOSKI, Auteur ; Evdokia ANAGNOSTOU, Auteur ; R. NICOLSON, Auteur ; E. KELLEY, Auteur ; S. GEORGIADES, Auteur ; X. LIU, Auteur ; R. A. STEVENSON, Auteur Article en page(s) : 67 p. Langues : Anglais (eng) Mots-clés : ADHD traits Adaptive behaviour Autism spectrum disorder Cluster analysis OCD traits Restrictive and repetitive behaviours Sensory phenotypes Sensory processing Social communication have no competing interests. Index. décimale : PER Périodiques Résumé : BACKGROUND: Atypical reactions to the sensory environment are often reported in autistic individuals, with a high degree of variability across the sensory modalities. These sensory differences have been shown to promote challenging behaviours and distress in autistic individuals and are predictive of other functions including motor, social, and cognitive abilities. Preliminary research suggests that specific sensory differences may cluster together within individuals creating discrete sensory phenotypes. However, the manner in which these sensory differences cluster, and whether the resulting phenotypes are associated with specific cognitive and social challenges is unclear. METHODS: Short sensory profile data from 599 autistic children and adults between the ages of 1 and 21 years were subjected to a K-means cluster analysis. Analysis of variances compared age, adaptive behaviour, and traits associated with autism, attention-deficit and hyperactivity disorder, and obsessive and compulsive disorder across the resultant clusters. RESULTS: A five-cluster model was found to minimize error variance and produce five sensory phenotypes: (1) sensory adaptive, (2) generalized sensory differences, (3) taste and smell sensitivity, (4) under-responsive and sensation seeking, and (5) movement difficulties with low energy. Age, adaptive behaviour, and traits associated with autism, attention-deficit and hyperactivity disorder, and obsessive and compulsive disorder were found to differ significantly across the five phenotypes. LIMITATIONS: The results were based on parent-report measures of sensory processing, adaptive behaviour, traits associated with autism, attention-deficit and hyperactivity disorder, and obsessive and compulsive disorder, which may limit the generalizability of the findings. Further, not all measures are standardized, or psychometrically validated with an autism population. Autistic individuals with an intellectual disability were underrepresented in this sample. Further, as these data were obtained from established records from a large provincial database, not all measures were completed for all individuals. CONCLUSIONS: These findings suggest that sensory difficulties in autistic individuals can be clustered into sensory phenotypes, and that these phenotypes are associated with behavioural differences. Given the large degree of heterogeneity in sensory difficulties seen in the autistic population, these sensory phenotypes represent an effective way to parse that heterogeneity and create phenotypes that may aid in the development of effective treatments and interventions for sensory difficulties.
