The current study extended examination of these processes to children with autism spectrum disorder (ASD), a group at considerable risk for sleep problems. Participants included 54 children with ASD (aged 6-10 years, 43% Hispanic). RSA data were collected via a wired MindWare system during a 3-min baseline and a 3-min challenge task. Parents reported on their children's sleep problems and sleep duration using the Children's Sleep Habits Questionnaire, Abbreviated. Although no significant correlations emerged between RSA indices and parent-reported child sleep, baseline RSA and RSA reactivity interacted in the prediction of sleep problems. For children with higher RSA reactivity, higher baseline RSA was associated with fewer sleep problems, but for children with lower RSA reactivity, baseline RSA was not predictive. No main effects or interactions of RSA predicted sleep duration. Findings suggest resilience against sleep problems for children with ASD presenting with higher baseline RSA and higher RSA reactivity. Implications of these results center upon directly targeting psychophysiology (i.e., parasympathetic nervous system regulation) as a possible mechanism to improve sleep in children with ASD, and developing personalized interventions based on physiological markers of risk and resilience.

Parasympathetic withdrawal indexes risk for emotion dysregulation in children with autism spectrum disorder / Jason K. BAKER in Autism Research, 15-11 (November 2022)  

Public ISBD [article]  inAutism Research > 15-11 (November 2022) . - p.2064-2068 Titre : Parasympathetic withdrawal indexes risk for emotion dysregulation in children with autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Jason K.

Theory and empirical evidence suggest substantial biological contributions to regulatory challenges, which may be related to core ASD symptoms. Respiratory sinus arrythmia (RSA) is a measure of parasympathetic nervous system activity that serves as a putative biomarker for emotion regulation. Higher baseline RSA and more RSA reactivity (parasympathetic withdrawal; RSA-R) in response to challenge appear adaptive in non-clinical populations, but existing evidence for children with ASD remains inconclusive. The current study examined correlates of observed emotion dysregulation in 61 children with ASD between the ages of 6 and 10 years, including ASD symptom levels as well as both baseline RSA and concurrent RSA reactivity. Consistent with previous research, ASD symptom level was significantly correlated with observed dysregulation whereas additional factors such as child IQ were not. Baseline RSA was unrelated to observed dysregulation, but higher RSA reactivity predicted concurrent dysregulation above and beyond the contribution of child ASD symptoms. Findings contribute to an emerging understanding of dysregulation in these children, raise questions about the utility of traditional baseline RSA measures for this population, and clarify the functional significance of RSA reactivity as a risk factor for emotion dysregulation in children with ASD.

Autonomic Dysregulation During Sensory Stimulation in Children with Autism Spectrum Disorder / Roseann C. SCHAAF 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.461-472 Titre : Autonomic Dysregulation During Sensory Stimulation in Children with Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Roseann C.

SENDECKI, Auteur Article en page(s) : p.461-472 Langues : Anglais (eng) Mots-clés : Autism spectrum disorders  Sensation  Autonomic nervous system  Parasympathetic nervous system  Sympathetic nervous system Index. décimale : PER Périodiques Résumé : Autonomic nervous system (ANS) activity during sensory stimulation was measured in 59 children with autism spectrum disorder (ASD) ages 6–9 in comparison to 30 typically developing controls. Multivariate comparisons revealed significant differences between groups in the respiratory sinus arrhythmia (parasympathetic measure) vector of means across sensory stimuli (p = 0.02) and in change from domain to domain (p = 0.01). Sympathetic activity, measured by pre-ejection period, did not differ significantly between groups, although it was higher in ASD participants. Findings suggest that participants with ASD demonstrated a different pattern of parasympathetic activity during sensory stimulation. Findings are discussed in relation to the biological mechanisms of sensory processing in autism, insight into the autism phenotype, and the utility of ANS activity as an outcomes marker.

Reduced heart rate variability in adults with autism spectrum disorder / R. THAPA in Autism Research, 12-6 (June 2019)  

Public ISBD [article]  inAutism Research > 12-6 (June 2019) . - p.922-930 Titre : Reduced heart rate variability in adults with autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : R.

GUASTELLA, Auteur Année de publication : 2019 Article en page(s) : p.922-930 Langues : Anglais (eng) Mots-clés : autonomic nervous system  biological marker  heart rate variability  mental health  parasympathetic nervous system  social development  sympathetic nervous system Index. décimale : PER Périodiques Résumé : A growing body of research has suggested heart rate variability (HRV) may be reduced in autism spectrum disorder (ASD) in comparison to neurotypical cohorts. While there have been several studies investigating HRV in children diagnosed with ASD, few studies have been conducted in adults. The objective of the current study was to investigate autonomic nervous system activity as assessed by HRV in adults diagnosed with ASD. We hypothesized that adults with ASD would show a reduction in HRV compared to neurotypical participants. Participants diagnosed with ASD (n = 55) were recruited from the Autism Clinic for Translational Research at the Brain and Mind Centre (University of Sydney) between 2013 and 2017. Neurotypical participants were recruited from advertisements and online media. Resting state heart rate was measured for 5 min while participants sat in an upright position. Results showed there was an overall significant difference in resting-state HRV between adults diagnosed with ASD compared to the neurotypical control group. Logarithmically transformed high frequency (HF) and root mean square of successive differences were particularly decreased in the ASD group, suggesting lower parasympathetic activity. The use of psychotropic medications and comorbidities were associated with reductions in low frequency of HRV. Our data suggest an overall dysregulation in resting autonomic activity in adults with ASD. This may represent an important physiological mechanism leading to potential cardiovascular risk in ASD, which warrants further investigation. Autism Res 2019, 12: 922-930. (c) 2019 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: ASD is commonly associated with a range of physical and mental health comorbidities. Autonomic disruptions underlying reductions in heart rate variability (HRV) have been linked to a range of mental and physical health conditions. We assessed resting-state HRV in adults diagnosed with ASD in comparison to healthy individuals. Our results showed reduced heart rate variability in people diagnosed with ASD compared to adults without ASD. These findings implicate a role for autonomic activity as a potentially modifiable risk factor for ASD.

Unusual sensory features are related to resting-state cardiac vagus nerve activity in autism spectrum disorders / Kanae MATSUSHIMA in Research in Autism Spectrum Disorders, 25 (May 2016)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 25 (May 2016) . - p.37-46 Titre : Unusual sensory features are related to resting-state cardiac vagus nerve activity in autism spectrum disorders Type de document : Texte imprimé et/ou numérique Auteurs : Kanae MATSUSHIMA, Auteur ; Jun MATSUBAYASHI, Auteur ; Motomi TOICHI, Auteur ; Yasuko FUNABIKI, Auteur ; Takeo KATO, Auteur ; Tomonari AWAYA, Auteur ; Toshihiro KATO, Auteur Article en page(s) : p.37-46 Langues : Anglais (eng) Mots-clés : Autism spectrum disorders  Sensory features  Parasympathetic nervous system  Resting state  Heart rate variability Index. décimale : PER Périodiques Résumé : The relationship between unusual sensory features (hyper-reactivity, hypo-reactivity, and unusual sensory interests) and the parasympathetic nervous system in autism spectrum disorder (ASD) has recently garnered interest. The purpose of this study was to investigate whether unusual sensory features are associated with resting-state cardiac vagus nerve activity in ASD children. Electrocardiogram signals were recorded during three 2-min resting periods to quantify the high frequency (HF) component of heart rate variability (HRV) in 37 children with ASD aged 6–12 and 32 typically developing children. Parent-reported questionnaires (Short Sensory Profile, SSP; Social Responsiveness Scale-2, SRS-2) assessed atypical sensory behaviors in daily life and autistic traits. Children with ASD consistently showed lower HF-HRV than typically developing children across the three resting periods. The SSP “Visual/Auditory Sensitivity” score was correlated with resting-state HF-HRV in the ASD group, indicating that ASD children with more severe visual/auditory hyper-reactivity in daily life have lower vagus nerve activity. The SRS-2 “Restricted Interests and Repetitive Behavior” score was also correlated with resting-state HF-HRV in the ASD group. These findings suggest that ASD children with lower vagus nerve activity may have inadequate self-regulatory capacity and difficulty regulating behavioral responses to unpredictable and unavoidable visual/auditory stimuli in daily life.
