Alpha oscillatory activity during attentional control in children with Autism Spectrum Disorder (ASD), Attention-Deficit/Hyperactivity Disorder (ADHD), and ASD+ADHD / Roser CAÑIGUERAL in Journal of Child Psychology and Psychiatry, 63-7 (July 2022)

Titre : Alpha oscillatory activity during attentional control in children with Autism Spectrum Disorder (ASD), Attention-Deficit/Hyperactivity Disorder (ADHD), and ASD+ADHD Type de document : Texte imprimé et/ou numérique Auteurs : Roser CAÑIGUERAL, Auteur ; Jason PALMER, Auteur ; Karen L. ASHWOOD, Auteur ; Bahar AZADI, Auteur ; Philip ASHERSON, Auteur ; Patrick F. BOLTON, Auteur ; Gráinne MCLOUGHLIN, Auteur ; Charlotte TYE, Auteur Article en page(s) : p.745-761 Langues : Anglais (eng) Mots-clés : Attention Deficit Disorder with Hyperactivity/diagnosis Autism Spectrum Disorder/diagnosis Child Executive Function/physiology Humans Reaction Time/physiology Adhd Autism Spectrum Disorder attention comorbidity Index. décimale : PER Périodiques Résumé : BACKGROUND: Autism Spectrum Disorder (ASD) and Attention-Deficit/Hyperactivity Disorder (ADHD) share impairments in top-down and bottom-up modulation of attention. However, it is not yet well understood if co-occurrence of ASD and ADHD reflects a distinct or additive profile of attention deficits. We aimed to characterise alpha oscillatory activity (stimulus-locked alpha desynchronisation and prestimulus alpha) as an index of integration of top-down and bottom-up attentional processes in ASD and ADHD. METHODS: Children with ASD, ADHD, comorbid ASD+ADHD, and typically-developing children completed a fixed-choice reaction-time task ('Fast task') while neurophysiological activity was recorded. Outcome measures were derived from source-decomposed neurophysiological data. Main measures of interest were prestimulus alpha power and alpha desynchronisation (difference between poststimulus and prestimulus alpha). Poststimulus activity linked to attention allocation (P1, P3), attentional control (N2), and cognitive control (theta synchronisation, 100-600?ms) was also examined. ANOVA was used to test differences across diagnostics groups on these measures. Spearman's correlations were used to investigate the relationship between attentional control processes (alpha oscillations), central executive functions (theta synchronisation), early visual processing (P1), and behavioural performance. RESULTS: Children with ADHD (ADHD and ASD+ADHD) showed attenuated alpha desynchronisation, indicating poor integration of top-down and bottom-up attentional processes. Children with ADHD showed reduced N2 and P3 amplitudes, while children with ASD (ASD and ASD+ADHD) showed greater N2 amplitude, indicating atypical attentional control and attention allocation across ASD and ADHD. In the ASD group, prestimulus alpha and theta synchronisation were negatively correlated, and alpha desynchronisation and theta synchronisation were positively correlated, suggesting an atypical association between attentional control processes and executive functions. CONCLUSIONS: ASD and ADHD are associated with disorder-specific impairments, while children with ASD+ADHD overall presented an additive profile with attentional deficits of both disorders. Importantly, these findings may inform the improvement of transdiagnostic procedures and optimisation of personalised intervention approaches.

METHODS: We explored parent-reported and directly-observed ASD symptoms on the Autism Diagnostic Interview-Revised (ADI-R) and the Autism Diagnostic Observation Schedule (ADOS) in children referred to ASD-specialty clinics who received diagnoses of either ADHD (n = 48) or ASD (n = 164). RESULTS: Of the ADHD sample, 21 % met ASD cut-offs on the ADOS and 30 % met ASD cut-offs on all domains of the ADI-R. Four social communication ADOS items (Quality of Social Overtures, Unusual Eye Contact, Facial Expressions Directed to Examiner, and Amount of Reciprocal Social Communication) adequately differentiated the groups while none of the items on the ADI-R met the criteria for adequate discrimination. CONCLUSIONS: Results of this work highlight the challenges that clinicians and researchers face when distinguishing ASD from other disorders in verbally fluent, school-age children.

Its original version and others in different countries are known to be effective tools in identifying individuals with autism spectrum disorder. This study examined whether the Hong Kong Chinese versions of the Autism-Spectrum Quotient-Child and Autism-Spectrum Quotient-Adolescent were effective in identifying autism spectrum disorder children and adolescents. On top of comparing them with their typically developing peers, this study also included a group of children/adolescents with attention deficit/hyperactivity disorder, a disorder with similar social difficulties as autism spectrum disorder. Results showed that both the Autism-Spectrum Quotient questionnaires were effective in differentiating the autism spectrum disorder group from the typically developing and attention-deficit/hyperactivity disorder groups, separately and jointly. On the contrary, they could not identify the attention-deficit/hyperactivity disorder group from the typically developing group so that they were not misclassifying attention-deficit/hyperactivity disorder as autism spectrum disorder. These findings supported that both the Autism-Spectrum Quotient-Child and Autism-Spectrum Quotient-Adolescent were not general measures of child and adolescent psychopathology, but could claim to be specific measures of autism spectrum disorder. Such capability would enormously enhance their utility in clinical practice for identifying autism spectrum disorder children/adolescents from their typically developing peers and from those with attention-deficit/hyperactivity disorder. This is because, the latter is a common neurodevelopmental disorder frequently presented to child psychiatric clinics alongside with autism spectrum disorder.

One new approach to this is prospective studies of infants with an elevated likelihood of developing ADHD. METHODS: We used a prospective design to examine an oscillatory electroencephalography profile that has been widely studied in both children and adults with ADHD - the balance between lower and higher frequencies operationalised as the theta-beta ratio (TBR). In the present study, we examined TBR in 136 10-month-old infants (72 male and 64 female) with/without an elevated likelihood of developing ADHD and/or a comparison disorder (Autism Spectrum Disorder; ASD). RESULTS: Infants with a first-degree relative with ADHD demonstrated lower TBR than infants without a first-degree relative with ADHD. Further, lower TBR at 10months was positively associated with temperament dimensions conceptually related to ADHD at 2years. TBR was not altered in infants with a family history of ASD. CONCLUSIONS: This is the first demonstration that alterations in TBR are present prior to behavioural symptoms of ADHD. However, these alterations manifest differently than those sometimes observed in older children with an ADHD diagnosis. Importantly, altered TBR was not seen in infants at elevated likelihood of developing ASD, suggesting a degree of specificity to ADHD. Taken together, these findings demonstrate that there are brain changes associated with a family history of ADHD observable in the first year of life.
