Subcortical structural changes have been associated with restricted and repetitive behavior (RRB), a core component of ASD. Behavioral studies have identified insistence on sameness (IS) as a separable RRB dimension prominent in high-functioning ASD, though no simple brain-behavior relationship has emerged. Structural covariance, a measure of morphological coupling among brain regions using magnetic resonance imaging (MRI), has proven an informative measure of anatomical relationships in typical development and neurodevelopmental disorders. In this study, we use this measure to characterize the relationship between brain structure and IS.

A preliminary study of self-reported food selectivity in adolescents and young adults with autism spectrum disorder / Emily S. KUSCHNER in Research in Autism Spectrum Disorders, 15-16 (July 2015)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 15-16 (July 2015) . - p.53-59 Titre : A preliminary study of self-reported food selectivity in adolescents and young adults with autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Emily S. KUSCHNER, Auteur ; Ian W. EISENBERG, Auteur ; Bako ORIONZI, Auteur ; W. Kyle SIMMONS, Auteur ; Lauren KENWORTHY, Auteur ; Alex MARTIN, Auteur ; Gregory L. WALLACE, Auteur Article en page(s) : p.53-59 Langues : Anglais (eng) Mots-clés : Autism  Food  Taste  Sensory  Adolescent  Adult Index. décimale : PER Périodiques Résumé : Although it is well-established that picky eating is a common feature of early development in autism spectrum disorder (ASD), far less is known about food selectivity during adolescence and adulthood. Using portions of the Adult/Adolescent Sensory Profile, food selectivity self-ratings were obtained from 65 high-functioning adolescents/young adults with ASD and compared to those of 59 typically developing controls matched on age, IQ, and sex ratio. Individuals with ASD reported preferring familiar foods (food neophobia) and disliking foods with particular textures and strong flavors. Providing linkage to everyday behavior, parent ratings of daily living skills were lower among individuals with ASD and food neophobia than among those without food neophobia. Food selectivity continues to be an important issue for adolescents/young adults with ASD.
