We found that participants with ASDs showed significantly longer PLR latency, smaller constriction amplitude and lower constriction velocity than children with typical development. The PLR latency alone can be used to discriminate the ASD group from the control group with a cross-validated success rate of 89.6%. By adding the constriction amplitude, the percentage of correct classification can be further improved to 92.5%. In addition, the right-lateralization of contraction anisocoria that was observed in participants with typical development was not observed in those with ASDs. Further studies are necessary to understand the origin and implications of these observations. It is anticipated that as potential biomarkers, these pupillary light reflex measurements will advance our understanding of neurodevelopmental differences in the autism brain.

Atypical Pupillary Light Reflex and Heart Rate Variability in Children with Autism Spectrum Disorder / Chathuri DALUWATTE in Journal of Autism and Developmental Disorders, 43-8 (August 2013)

Heart rate variability (HRV) was measured simultaneously to study potential impairments in the autonomic nervous system (ANS) associated with ASD. The results showed that the ASD group had significantly longer PLR latency, reduced relative constriction amplitude, and shorter constriction/redilation time than those of the TD group. Similar atypical PLR parameters were observed in the NDD group. A significant age effect on PLR latency was observed in children younger than 9 years in the TD group, but not in the ASD and NDD groups. Atypical HRV parameters were observed in the ASD and NDD groups. A significant negative correlation existed between the PLR constriction amplitude and average heart rate in children with an ASD, but not in children with typical development.

Atypical pupillary light reflex in 2–6-year-old children with autism spectrum disorders / Dinalankara M.R. DINALANKARA in Autism Research, 10-5 (May 2017)

A total of 117 medication-free 2–6-year-old boys participated in this study. Sixty participants were diagnosed with ASD (the “ASD group”) and the other 57 were in the control group of typical development (the “TD group”). A questionnaire was completed by the parent/guardian for assessing potential dysfunctions in the autonomic nervous system (ANS). The base pupil radius, PLR latency, and constriction time showed a significant age-related trend in both the ASD and TD groups. The base pupil size increased with age in the typically developing children, but not in the ASD group. The ASD group showed more symptoms related to ANS dysfunctions. An association between abnormal sweating with base pupil radius and PLR constriction was observed in the TD group but not the ASD group. The different association of PLR parameters with ANS dysfunction may suggest disrupted autonomic controls in children with ASD.

Cognitive behavioral treatment of insomnia in school-aged children with autism spectrum disorder: A pilot feasibility study / Christina S. MCCRAE in Autism Research, 13-1 (January 2020)

MAZUREK, Auteur Article en page(s) : p.167-176 Langues : Anglais (eng) Mots-clés : autism  behavior  child  cognitive behavioral therapy  insomnia  parent Index. décimale : PER Périodiques Résumé : Insomnia is common in autism and associated with challenging behavior and worse parent sleep. Cognitive behavioral treatment for childhood insomnia (CBT-CI) is efficacious in typically developing children, but not yet tested in school-aged children with autism. This single arm pilot tested 8-session CBT-CI in 17 children with autism and insomnia (M age = 8.76 years, SD = 1.99) and their parent(s) (M age = 39.50 years, SD = 4.83). Treatment integrity was assessed for each session [delivery (by therapist), receipt (participant understanding), and enactment (home practice)]. Children and parents wore actigraphs and completed electronic diaries for 2-weeks to obtain objective and subjective sleep onset latency (SOL), total sleep/wake times (TST/TWT), and sleep efficiency (SE) at pre/post/1-month follow-up. Parents also completed the Aberrant Behavior Checklist [irritability, lethargy, stereotypy, hyperactivity, inappropriate speech (e.g., excessive/repetitive, loud self-talk)] at pre/post/1-month. Fifteen children completed all sessions. Average integrity scores were high [90%-delivery/receipt, 87.5%-enactment]. Parents found CBT-CI helpful, age-appropriate, and autism-friendly. Paired samples t-tests (family-wise error controlled) found CBT-CI improved child sleep (objective SOL-18 min, TWT- 34 min, SE-5%; subjective SOL-29 min, TST-63 min, TWT-45 min, SE-8%), and decreased irritability, lethargy, stereotypy, and hyperactivity. At 1-month, objective TST improved, inappropriate speech decreased, but hyperactivity was no longer decreased. Other gains were maintained. Parent sleep (objective SOL-12 min, TST-35 min, TWT-21 min, SE-4%; subjective SOL-11 min, TWT- 31min, SE-11%) and fatigue also improved. At 1-month, gains were maintained. This pilot shows CBT-CI is a feasible treatment that holds promise for improving child and parent sleep and functioning and suggests a randomized controlled trial in school-aged children with autism is worth conducting. Autism Res 2020, 13: 167-176. (c) 2019 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: Insomnia is common in autism and associated with challenging behaviors and poor parent sleep and stress. Cognitive behavioral treatment for childhood insomnia (CBT-CI) has not been tested in school-aged children with autism. This pilot study shows therapists, parents, and children were able to use CBT-CI to improve child and parent sleep, child behavior, and parent fatigue. Parents found CBT-CI helpful, age-appropriate, and autism-friendly. CBT-CI holds promise for treating insomnia in school-aged children with autism and deserves further testing.

Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : BACKGROUND: Heterogeneous mental health outcomes during the COVID-19 pandemic are documented in the general population. Such heterogeneity has not been systematically assessed in youth with autism spectrum disorder (ASD) and related neurodevelopmental disorders (NDD). To identify distinct patterns of the pandemic impact and their predictors in ASD/NDD youth, we focused on pandemic-related changes in symptoms and access to services. METHODS: Using a naturalistic observational design, we assessed parent responses on the Coronavirus Health and Impact Survey Initiative (CRISIS) Adapted For Autism and Related neurodevelopmental conditions (AFAR). Cross-sectional AFAR data were aggregated across 14 European and North American sites yielding a clinically well-characterized sample of N=1275 individuals with ASD/NDD (age=11.0+3.6 years; n females=277). To identify subgroups with differential outcomes, we applied hierarchical clustering across eleven variables measuring changes in symptoms and access to services. Then, random forest classification assessed the importance of socio-demographics, pre-pandemic service rates, clinical severity of ASD-associated symptoms, and COVID-19 pandemic experiences/environments in predicting the outcome subgroups. RESULTS: Clustering revealed four subgroups. One subgroup-broad symptom worsening only (20%)-included youth with worsening across a range of symptoms but with service disruptions similar to the average of the aggregate sample. The other three subgroups were, relatively, clinically stable but differed in service access: primarily modified services (23%), primarily lost services (6%), and average services/symptom changes (53%). Distinct combinations of a set of pre-pandemic services, pandemic environment (e.g., COVID-19 new cases, restrictions), experiences (e.g., COVID-19 Worries), and age predicted each outcome subgroup. LIMITATIONS: Notable limitations of the study are its cross-sectional nature and focus on the first six months of the pandemic. CONCLUSIONS: Concomitantly assessing variation in changes of symptoms and service access during the first phase of the pandemic revealed differential outcome profiles in ASD/NDD youth. Subgroups were characterized by distinct prediction patterns across a set of pre- and pandemic-related experiences/contexts. Results may inform recovery efforts and preparedness in future crises; they also underscore the critical value of international data-sharing and collaborations to address the needs of those most vulnerable in times of crisis.
