Attention deficit/hyperactivity disorder symptoms moderate cognition and behavior in children with autism spectrum disorders / Benjamin E. YERYS in Autism Research, 2-6 (December 2009)  

Public ISBD [article]  inAutism Research > 2-6 (December 2009) . - p.322-333 Titre : Attention deficit/hyperactivity disorder symptoms moderate cognition and behavior in children with autism spectrum disorders Type de document : Texte imprimé et/ou numérique Auteurs : Benjamin E. YERYS, Auteur ; Gregory L. WALLACE, Auteur ; Lauren E. KENWORTHY, Auteur ; Jennifer L. SOKOLOFF, Auteur ; Devon A. SHOOK, Auteur ; Joette D. JAMES, Auteur Année de publication : 2009 Article en page(s) : p.322-333 Langues : Anglais (eng) Mots-clés : clinical-psychology neuropsychology school-age Index. décimale : PER Périodiques Résumé : Recent estimates suggest that 31% of children with autism spectrum disorders (ASD) meet diagnostic criteria for attention deficit/hyperactivity disorder (ADHD), and another 24% of children with ASD exhibit subthreshold clinical ADHD symptoms. Presence of ADHD symptoms in the context of ASD could have a variety of effects on cognition, autistic traits, and adaptive/maladaptive behaviors including: exacerbating core ASD impairments; adding unique impairments specific to ADHD; producing new problems unreported in ASD or ADHD; having no clear impact; or producing some combination of these scenarios. Children with ASD and co-morbid ADHD symptoms (ASD+ADHD; n=21), children with ASD without ADHD (ASD; n=28), and a typically developing control group (n=21) were included in the study; all groups were matched on age, gender-ratio, IQ, and socioeconomic status. Data were collected on verbal and spatial working memory, response inhibition, global executive control (EC), autistic traits, adaptive functioning, and maladaptive behavior problems. In this sample, the presence of ADHD symptoms in ASD exacerbated impairments in EC and adaptive behavior and resulted in higher autistic trait, and externalizing behavior ratings. ADHD symptoms were also associated with greater impairments on a lab measure of verbal working memory. These findings suggest that children with ASD+ADHD symptoms present with exacerbated impairments in some but not all domains of functioning relative to children with ASD, most notably in adaptive behavior and working memory. Therefore, ADHD may moderate the expression of components of the ASD cognitive and behavioral phenotype, but ASD+ADHD may not represent an etiologically distinct phenotype from ASD alone.

Interests in high-functioning autism are more intense, interfering, and idiosyncratic than those in neurotypical development / Laura G. ANTHONY in Development and Psychopathology, 25-3 (August 2013)  

Public ISBD [article]  inDevelopment and Psychopathology > 25-3 (August 2013) . - p.643-652 Titre : Interests in high-functioning autism are more intense, interfering, and idiosyncratic than those in neurotypical development Type de document : Texte imprimé et/ou numérique Auteurs : Laura G. ANTHONY, Auteur ; Lauren E. KENWORTHY, Auteur ; Benjamin E. YERYS, Auteur ; Kathryn F. JANKOWSKI, Auteur ; Joette D. JAMES, Auteur ; Madeline B. HARMS, Auteur ; Alex MARTIN, Auteur ; Gregory L. WALLACE, Auteur Article en page(s) : p.643-652 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Although circumscribed interests are pathognomonic with autism, much about these interests remains unknown. Using the Interests Scale (IS), this study compares interests between 76 neurotypical (NT) individuals and 109 individuals with high-functioning autism spectrum disorder (HF-ASD) matched groupwise on age, IQ, and gender ratio. Participants and their parents/caregivers completed diagnostic measures (the Autism Diagnostic Interview—Revised and the Autism Diagnostic Observation Schedule; HF-ASD only), cognitive tests (Wechsler IQ Scales), and questionnaires (the Repetitive Behavior Scale—Revised, the Behavior Rating Inventory of Executive Function, and the Social Responsiveness Scale), in addition to the IS. Consistent with previous research, HF-ASD and NT individuals did not differ in number of interest areas, but the types of interests and intensity of those interests differed considerably. Using only the IS intensity score, 81% of individuals were correctly classified (NT or HF-ASD) in a logistic regression analysis. Among individuals with HF-ASD, Interests Scale scores were significantly related to Autism Diagnostic Observation Schedule, Behavior Rating Inventory of Executive Function, Repetitive Behavior Scale—Revised, and Social Responsiveness Scale scores, but they were not related to Autism Diagnostic Interview—Revised scores, IQ, gender, age, or psychotropic medication use. The type and intensity, but not the number, of interests distinguish high-functioning individuals with ASD from NT individuals.
