Assessing the Contribution of Measures of Attention and Executive Function to Diagnosis of ADHD or Autism / Kelsey HARKNESS in Journal of Autism and Developmental Disorders, 55-4 (April 2024)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 55-4 (April 2024) . - p.1353-1364 Titre : Assessing the Contribution of Measures of Attention and Executive Function to Diagnosis of ADHD or Autism Type de document : texte imprimé Auteurs : Kelsey HARKNESS, Auteur ; Signe BRAY, Auteur ; Chelsea DURBER, Auteur ; Deborah DEWEY, Auteur ; Kara MURIAS, Auteur Article en page(s) : p.1353-1364 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Attention and executive function (EF) dysregulation are common in a number of disorders including autism and attention-deficit/hyperactivity disorder (ADHD). Better understanding of the relationship between indirect and direct measures of attention and EF and common neurodevelopmental diagnoses may contribute to more efficient and effective diagnostic assessment in childhood. We obtained cognitive (NIH Toolbox, Little Man Task, Matrix Reasoning Task, and Rey Delayed Recall) and symptom (CBCL, and BPMT) assessment data from the Adolescent Brain and Cognitive Development (ABCD) database for three groups, autistic (N = 110), ADHD (N = 878), and control without autism or ADHD diagnoses (N = 9130) and used ridge regression to determine which attention and EF assessments were most strongly associated with autism or ADHD. More variance was accounted for in the model for the ADHD group (31%) compared to the autism group (2.7%). Finally, we ran odds ratios (using clinical cutoffs where available and 2 standard deviations below the mean when not) for each assessment measure, which generally demonstrated a greater significance within the indirect measures when compared to the direct measures. These results add to the growing literature of symptom variably across diagnostic groups allowing for better understanding of presentations in autism and ADHD and how best to assess diagnosis. It also highlights the increased difficulty in differentiating autism and controls when compared to ADHD and controls and the importance of indirect measures of attention and EF in this differentiation.

Atypical Tactile Perception in Early Childhood Autism / Svenja ESPENHAHN in Journal of Autism and Developmental Disorders, 53-7 (July 2023)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 53-7 (July 2023) . - p.2891-2904 Titre : Atypical Tactile Perception in Early Childhood Autism Type de document : texte imprimé Auteurs : Svenja ESPENHAHN, Auteur ; Kate J. GODFREY, Auteur ; Sakshi KAUR, Auteur ; Carly MCMORRIS, Auteur ; Kara MURIAS, Auteur ; Mark TOMMERDAHL, Auteur ; Signe BRAY, Auteur ; Ashley D. HARRIS, Auteur Article en page(s) : p.2891-2904 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : We assessed different aspects of tactile perception in young children (3-6 years) with autism. Autistic and neurotypical children completed vibrotactile tasks assessing reaction time, amplitude discrimination (sequential and simultaneous) and temporal discrimination (temporal order judgment and duration discrimination). Autistic children had elevated and more variable reaction times, suggesting slower perceptual-motor processing speed and/or greater distractibility. Children with autism also showed higher amplitude discrimination and temporal order judgement thresholds compared to neurotypical children. Tactile perceptual metrics did not associate with social or tactile sensitivities measured by parent-reports. Altered tactile behavioral responses appear in early childhood, can be quantified but appear dissociated from sensitivity. This implies these measures are complementary, but not necessarily related, phenomena of atypical tactile perception in autism.

Functional connectivity based brain signatures of behavioral regulation in children with ADHD, DCD, and ADHD-DCD / Christiane S. ROHR in Development and Psychopathology, 35-1 (February 2023)  

Public ISBD [article]  inDevelopment and Psychopathology > 35-1 (February 2023) . - p.85-94 Titre : Functional connectivity based brain signatures of behavioral regulation in children with ADHD, DCD, and ADHD-DCD Type de document : texte imprimé Auteurs : Christiane S.

Here, we investigated transdiagnostic brain signatures associated with behavioral regulation. Resting-state fMRI data were collected from 115 children (31 typically developing (TD), 35 ADHD, 21 DCD, 28 ADHD-DCD) aged 7-17 years. Behavioral regulation was measured using the Behavior Rating Inventory of Executive Function and was found to differ between children with ADHD (i.e., children with ADHD and ADHD-DCD) and without ADHD (i.e., TD children and children with DCD). Functional connectivity (FC) maps were computed for 10 regions of interest and FC maps were tested for correlations with behavioral regulation scores. Across the entire sample, greater behavioral regulation problems were associated with stronger negative FC within prefrontal pathways and visual reward pathways, as well as with weaker positive FC in frontostriatal reward pathways. These findings significantly increase our knowledge on FC in children with and without ADHD and highlight the potential of FC as brain-based signatures of behavioral regulation across children with differing neurodevelopmental conditions.
