While numerous neuroimaging studies have investigated executive circuits as putative neural substrates of repetitive behavior, recent work implicates affective neural circuits in restricted interests. We sought to explore the role of affective neural circuits and determine how restricted interests are distinguished from hobbies or interests in typical development. Methods We compared a group of children with ASD to a typically developing (TD) group of children with strong interests or hobbies, employing parent report, an operant behavioral task, and functional imaging with personalized stimuli based on individual interests. Results While performance on the operant task was similar between the two groups, parent report of intensity and interference of interests was significantly higher in the ASD group. Both the ASD and TD groups showed increased BOLD response in widespread affective neural regions to the pictures of their own interest. When viewing pictures of other children's interests, the TD group showed a similar pattern, whereas BOLD response in the ASD group was much more limited. Increased BOLD response in the insula and anterior cingulate cortex distinguished the ASD from the TD group, and parent report of the intensity and interference with daily life of the child's restricted interest predicted insula response. Conclusions While affective neural network response and operant behavior are comparable in typical and restricted interests, the narrowness of focus that clinically distinguishes restricted interests in ASD is reflected in more interference in daily life and aberrantly enhanced insula and anterior cingulate response to individuals’ own interests in the ASD group. These results further support the involvement of affective neural networks in repetitive behaviors in ASD.

A community-based sleep educational intervention for children with autism spectrum disorder / Lydia L. MACDONALD in Research in Autism Spectrum Disorders, 81 (March 2021)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 81 (March 2021) . - 101719 Titre : A community-based sleep educational intervention for children with autism spectrum disorder Type de document : texte imprimé Auteurs : Lydia L. MACDONALD, Auteur ; Laura GRAY, Auteur ; Whitney A. LORING, Auteur ; Amanda WYATT, Auteur ; Kemberlee BONNET, Auteur ; David SCHLUND, Auteur ; Mary Landis GAST, Auteur ; Beth A. MALOW, Auteur Article en page(s) : 101719 Langues : Anglais (eng) Mots-clés : Sleep education  Autism spectrum disorder  Community  Children’s Sleep Habits Questionnaire Index. décimale : PER Périodiques Résumé : Background Sleep problems are common in children with autism spectrum disorder (ASD). Sleep education, effective in improving sleep in ASD, may be difficult to access. We determined if community-based pediatric therapists could successfully deliver sleep educational interventions to caregivers of children with ASD. Methods A seven-week feasibility study was conducted consisting of 10 children and caregivers. This feasibility study informed the development of a 16-week preliminary effectiveness study, which consisted of 33 children and caregivers. Children, ages 2–12 years, with a clinical diagnosis of autism and caregiver-reported sleep onset delay of 30 min were included. Community therapists underwent comprehensive training in sleep education and then met with caregiver participants to provide sleep education to each family. Semi-structured qualitative interviews were conducted with all families who completed study procedures. In the feasibility and preliminary effectiveness studies, child participants wore an actigraphy watch (at baseline and after sleep education) and caregivers completed the Child Sleep Habits Questionnaire and Family Inventory of Sleep Habits at baseline and after sleep education; the Child Behavior Checklist was also completed by caregivers in the preliminary effectiveness study. Results Educator fidelity to the manualized curriculum was maintained. Caregivers showed appropriate understanding, comfort, and implementation of the curriculum. Qualitative and quantitative measures, including caregiver surveys and actigraphy, showed improvements in child sleep and behavior. Conclusions Community-based therapists can successfully deliver sleep education to families of children with ASD, which has favorable implications for improving access to care in this population.

A pilot investigation of an iOS-based app for toilet training children with autism spectrum disorder / Daniel W. MRUZEK in Autism, 23-2 (February 2019)

YORK, Auteur ; Katherine ZANIBBI, Auteur Article en page(s) : p.359-370 Langues : Anglais (eng) Mots-clés : autism spectrum disorder  enuresis  randomized controlled trial  technology  toilet training  urine alarm Index. décimale : PER Périodiques Résumé : We developed an iOS-based app with a transmitter/disposable sensor and corresponding manualized intervention for children with autism spectrum disorder. The app signaled the onset of urination, time-stamped accidents for analysis, reminded parents to reinforce intervals of continence, provided a visual outlet for parents to communicate reinforcement, and afforded opportunity for timely feedback from clinicians. We compared this intervention with an intervention that uses standard behavioral treatment in a pilot randomized controlled trial of 33 children with autism spectrum disorder aged 3-6 years with urinary incontinence. Parents in both groups received initial training and four booster consultations over 3 months. Results support the feasibility of parent-mediated toilet training studies (e.g., 84% retention rate, 92% fidelity of parent-implemented intervention). Parents used the app and related technology with few difficulties or malfunctions. There were no statistically significant group differences for rate of urine accidents, toilet usage, or satisfaction at close of intervention or 3-month follow-up; however, the alarm group trended toward greater rate of skill acquisition with significantly less day-to-day intervention. Further development of alarm and related technology and future comparative studies with a greater number of participants are warranted.
