Cardiac Reactivity and Stimulant Use in Adolescents with Autism Spectrum Disorders with Comorbid ADHD Versus ADHD / Marleen BINK in Journal of Autism and Developmental Disorders, 45-2 (February 2015)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 45-2 (February 2015) . - p.481-494 Titre : Cardiac Reactivity and Stimulant Use in Adolescents with Autism Spectrum Disorders with Comorbid ADHD Versus ADHD Type de document : texte imprimé Auteurs : Marleen BINK, Auteur ; Arne POPMA, Auteur ; Ilja L. BONGERS, Auteur ; G.J.M. VAN BOXTEL, Auteur ; A.

However, previous studies are not conclusive whether psychophysiological correlates, like cardiac reactivity, are different for ASD with comorbid ADHD (ASD+) compared to ADHD. Therefore, the current study investigated (dis)similarities in cardiac reactivity and attention task performance. In a clinical sample, adolescents diagnosed with ASD+ (n = 20) versus ADHD (n = 36) and stimulant medication use (56 %) were compared during a baseline with eyes closed and task performance. Results for cardiac reactivity were similar for both diagnostic groups. Stimulant-medicated adolescents showed decreased adaptation of LF/HF ratio and faster reaction times than stimulant-free adolescents. The current study underlines the psychophysiological overlap of ADHD symptoms in adolescents with ASD+ and adolescents with ADHD.

Vagal Tone as a Putative Mechanism for Pragmatic Competence: An Investigation of Carriers of the FMR1 Premutation / Jessica KLUSEK in Journal of Autism and Developmental Disorders, 49-1 (January 2019)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 49-1 (January 2019) . - p.197-208 Titre : Vagal Tone as a Putative Mechanism for Pragmatic Competence: An Investigation of Carriers of the FMR1 Premutation Type de document : texte imprimé Auteurs : Jessica KLUSEK, Auteur ; Amanda J. FAIRCHILD, Auteur ; Jane E. ROBERTS, Auteur Article en page(s) : p.197-208 Langues : Anglais (eng) Mots-clés : Fragile X carrier  Hrv  Rsa  Social (Pragmatic) Communication Disorder  Social communication Index. décimale : PER Périodiques Résumé : Pragmatic language skills exist across a continuum in typical and clinical populations, and are impaired in many neurodevelopmental disorders, most notably autism. The mechanisms underlying pragmatic impairment are poorly understood, although theory suggests dampened vagal tone plays a role. This study investigated the FMR1 premutation as a genetic model that may lend insight into the relationship between vagal function and pragmatic ability. Participants included 38 women with the FMR1 premutation and 23 controls. Vagal tone accounted for significant variance in pragmatics across both groups and statistically mediated the effect of FMR1 premutation status on pragmatic ability. Results support vagal tone as a biophysiological correlate of pragmatic ability, which informs potential mechanistic underpinnings and could have implications for targeted treatment.
