ADHD and autism symptoms in youth: a network analysis / L. 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 et/ou numérique Auteurs : L. C. FARHAT, Auteur ; Helena BRENTANI, Auteur ; V. H. C. DE TOLEDO, Auteur ; E. SHEPHARD, Auteur ; P. MATTOS, Auteur ; Simon BARON-COHEN, Auteur ; A. THAPAR, Auteur ; E. 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.

Commentary: Identifying individualized predictions of response in ADHD pharmacotherapy - a commentary on Rodrigues et al. (2020) / L. C. FARHAT in Journal of Child Psychology and Psychiatry, 62-6 (June 2021)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 62-6 (June 2021) . - p.701-703 Titre : Commentary: Identifying individualized predictions of response in ADHD pharmacotherapy - a commentary on Rodrigues et al. (2020) Type de document : Texte imprimé et/ou numérique Auteurs : L. C. FARHAT, Auteur ; Michael H. BLOCH, Auteur Article en page(s) : p.701-703 Langues : Anglais (eng) Mots-clés : Atomoxetine Hydrochloride/pharmacology  Attention Deficit Disorder with Hyperactivity/drug therapy  Autism Spectrum Disorder/drug therapy  Child  Guanfacine/pharmacology  Humans  Methylphenidate/pharmacology Index. décimale : PER Périodiques Résumé : In this issue, Rodrigues et al. (2020) present a systematic review with meta-analyses that reports the efficacy of five treatments for children with attention-deficit hyperactivity disorder symptoms in the context of autism spectrum disorder - (a) methylphenidate; (b) atomoxetine; (c) guanfacine; (d) aripiprazole; and (e) risperidone. In this commentary, we highlight the contrast between the scarce evidence base of treatment for ADHD in the context of autism and other subpopulations, such as tic disorders and intellectual disability, and the extensive evidence base of treatment for ADHD in general. The commentary weighs about the conundrum clinicians face of whether to rely on the limited evidence base of treatment for ADHD in subpopulation, or to derive conclusions from the larger body of evidence of treatment for ADHD in general. The commentary also discusses potential avenues for future research to address this clinical problem.
