Adaptive Behaviour and Cognitive Skills: Stability and Change from 7 Months to 7 Years in Siblings at High Familial Risk of Autism Spectrum Disorder / Erica SALOMONE in Journal of Autism and Developmental Disorders, 48-9 (September 2018)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 48-9 (September 2018) . - p.2901-2911 Titre : Adaptive Behaviour and Cognitive Skills: Stability and Change from 7 Months to 7 Years in Siblings at High Familial Risk of Autism Spectrum Disorder Type de document : texte imprimé Auteurs : Erica SALOMONE, Auteur ; Elizabeth SHEPHARD, Auteur ; Bosiljka MILOSAVLJEVIC, Auteur ; Mark Henry JOHNSON, Auteur ; Tony CHARMAN, Auteur Article en page(s) : p.2901-2911 Langues : Anglais (eng) Mots-clés : Adaptive behaviour  Cognitive ability  High familial risk  Prospective study Index. décimale : PER Périodiques Résumé : Cognitive and adaptive behaviour abilities early in life provide important clinical prognostic information. We examined stability of such skills in children at high familial risk for ASD who either met diagnostic criteria for ASD at age 7 years (HR-ASD, n = 15) or did not (HR-non-ASD, n = 24) and low-risk control children (LR, n = 37), prospectively studied from infancy. For both HR groups, cognitive skills were consistently lower across time than those of LR children. HR-ASD children showed increasing difficulties in adaptive behaviour over time compared to LR children, while the HR-non-ASD children showed no such difficulties. This pattern of change may inform our understanding of developmental profiles of HR siblings beyond core ASD symptoms.

ADHD and autism symptoms in youth: a network analysis / Luis C. FARHAT in Journal of Child Psychology and Psychiatry, 63-2 (February 2022)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 63-2 (February 2022) . - p.143-151 Titre : ADHD and autism symptoms in youth: a network analysis Type de document : texte imprimé Auteurs : Luis C. FARHAT, Auteur ; Helena BRENTANI, Auteur ; Victor Hugo Calegari DE TOLEDO, Auteur ; Elizabeth SHEPHARD, Auteur ; Paulo MATTOS, Auteur ; Simon BARON-COHEN, Auteur ; Anita THAPAR, Auteur ; Erasmo CASELLA, Auteur ; Guilherme V. POLANCZYK, Auteur Article en page(s) : p.143-151 Langues : Anglais (eng) Mots-clés : Attention-deficit hyperactivity disorder  autism spectrum disorder  comorbidity  network analysis  neurodevelopmental Index. décimale : PER Périodiques Résumé : BACKGROUND: Previous research investigating the overlap between attention-deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (henceforth, autism) symptoms in population samples have relied on latent variable modeling in which averaged scores representing dimensions were derived from observed symptoms. There are no studies evaluating how ADHD and autism symptoms interact at the level of individual symptom items. METHODS: We aimed to address this gap by performing a network analysis on data from a school survey of children aged 6-17 years old (N = 7,405). ADHD and autism symptoms were measured via parent-report on the Swanson, Nolan, Pelham-IV questionnaire and the Childhood Autism Spectrum test, respectively. RESULTS: A relatively low interconnectivity between ADHD and autism symptoms was found with only 10.06% of possible connections (edges) between one ADHD and one autism symptoms different than zero. Associations between ADHD and autism symptoms were significantly weaker than those between two symptoms pertaining to the same construct. Select ADHD symptoms, particularly those presenting in social contexts (e.g. 'talks excessively', 'does not wait turn'), showed moderate-to-strong associations with autism symptoms, but some were considered redundant to autism symptoms. CONCLUSIONS: The present findings indicate that individual ADHD and autism symptoms are largely segregated in accordance with diagnostic boundaries corresponding to these conditions in children and adolescents from the community. These findings could improve our clinical conceptualization of ADHD and autism and guide advancements in diagnosis and treatment.

Anxiety and Attentional Bias to Threat in Children at Increased Familial Risk for Autism Spectrum Disorder / Bosiljka MILOSAVLJEVIC in Journal of Autism and Developmental Disorders, 47-12 (December 2017)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 47-12 (December 2017) . - p.3714-3727 Titre : Anxiety and Attentional Bias to Threat in Children at Increased Familial Risk for Autism Spectrum Disorder Type de document : texte imprimé Auteurs : Bosiljka MILOSAVLJEVIC, Auteur ; Elizabeth SHEPHARD, Auteur ; Francesca HAPPE, Auteur ; Mark Henry JOHNSON, Auteur ; Tony CHARMAN, Auteur Année de publication : 2017 Article en page(s) : p.3714-3727 Langues : Anglais (eng) Mots-clés : Anxiety  Autism Spectrum Disorder  High-risk siblings  Threat bias Index. décimale : PER Périodiques Résumé : Anxiety and threat bias were examined in 6-8-year-old children at familial-risk for Autism Spectrum Disorder (ASD) and low-risk (LR, n = 37) controls. The high-risk (HR) group was divided into those who met diagnostic criteria for ASD (HR-ASD, n = 15) and those who did not (HR-non ASD, n = 24). The HR-ASD group had highest levels of parent-reported anxiety. The HR-non ASD group exhibited increased threat bias on a spatial-cueing task, while the HR-ASD group did not. Anxiety symptoms were associated with both threat bias and ASD severity. These findings suggest that the mechanisms underlying anxiety in HR siblings without ASD are similar to those in non-ASD populations. However, among children with ASD, hypersensitivity to threat may not underlie anxiety symptoms.

Brief Report: Associations Between Cognitive Control Processes and Traits of Autism Spectrum Disorder (ASD), attention-Deficit/Hyperactivity Disorder (ADHD) and Anxiety in Children at Elevated and Typical Familial Likelihood for ASD / Priscilla B.G.

We investigated how different cognitive control processes (inhibitory control, conflict resolution, cognitive flexibility) associated with traits of autism spectrum disorder (ASD), attention-deficit/hyperactivity disorder (ADHD) and anxiety in 7-year-old children at elevated (n = 44) and typical (n = 37) familial likelihood for ASD. Poor inhibitory control was associated with higher ADHD traits. Better inhibitory control and poorer cognitive flexibility predicted higher anxiety traits. Cognitive control processes were not associated dimensionally with autistic traits, though better conflict resolution predicted greater likelihood of meeting diagnostic criteria for ASD in categorical analysis. These findings suggest that different cognitive control alterations are associated with ASD, ADHD and anxiety.
