The relationship between autism symptoms and arousal level in toddlers with autism spectrum disorder, as measured by electrodermal activity / Emily Barbara PRINCE in Autism, 21-4 (May 2017)

Titre : The relationship between autism symptoms and arousal level in toddlers with autism spectrum disorder, as measured by electrodermal activity Type de document : Texte imprimé et/ou numérique Auteurs : Emily Barbara PRINCE, Auteur ; Elizabeth S KIM, Auteur ; Carla A. WALL, Auteur ; Eugenia GISIN, Auteur ; Matthew S GOODWIN, Auteur ; Elizabeth SCHOEN SIMMONS, Auteur ; Kasia CHAWARSKA, Auteur ; Frederick SHIC, Auteur Article en page(s) : p.504-508 Langues : Anglais (eng) Mots-clés : ASD electrodermal activity galvanic skin response language naturalistic environment play skin conductance toddlers Index. décimale : PER Périodiques Résumé : Electrodermal activity was examined as a measure of physiological arousal within a naturalistic play context in 2-year-old toddlers (N?=?27) with and without autism spectrum disorder. Toddlers with autism spectrum disorder were found to have greater increases in skin conductance level than their typical peers in response to administered play activities. In the autism spectrum disorder group, a positive relationship was observed between restrictive and repetitive behaviors and skin conductance level increases in response to mechanical toys, whereas the opposite pattern was observed for passive toys. This preliminary study is the first to examine electrodermal activity levels in toddlers with autism spectrum disorder during play-based, naturalistic settings, and it highlights the potential for electrodermal activity as a measure of individual variability within autism spectrum disorder and early development.

Titre : Lower Electrodermal Activity to Acute Stress in Caregivers of People with Autism Spectrum Disorder: An Adaptive Habituation to Stress Type de document : Texte imprimé et/ou numérique Auteurs : Nicolás RUIZ-ROBLEDILLO, Auteur ; Luis MOYA-ALBIOL, Auteur Article en page(s) : p.576-588 Langues : Anglais (eng) Mots-clés : Electrodermal activity Caregivers Autism spectrum disorder Autonomic nervous system Health Index. décimale : PER Périodiques Résumé : Caring for a relative with autism spectrum disorder (ASD) entails being under chronic stress that could alter body homeostasis. Electrodermal activity (EDA) is an index of the sympathetic activity of the autonomic nervous system related to emotionality and homeostasis. This study compares EDA in response to acute stress in the laboratory between parents of people with (n = 30) and without (n = 34) ASD (caregivers and non-caregivers, respectively). Caregivers showed lower EDA in response to acute stress than non-caregivers. They also presented higher trait anxiety, anger, depression, and somatic symptoms than non-caregivers. Higher EDA was related to a worse mood and more severe somatic symptoms only in caregivers. These results could reflect an adaptive habituation to stress and establish that high EDA in response to acute stress depends on caregivers’ health.

[article]
Titre : Trial-to-Trial Variability in Electrodermal Activity to Odor in Autism Type de document : Texte imprimé et/ou numérique Auteurs : Sarah M. HAIGH, Auteur ; Yaara ENDEVELT-SHAPIRA, Auteur ; Marlene BEHRMANN, Auteur Article en page(s) : p.2083-2093 Langues : Anglais (eng) Mots-clés : autism electrodermal activity faces fear trial-to-trial variability Index. décimale : PER Périodiques Résumé : Abnormal trial-to-trial variability (TTV) has been identified as a key feature of neural processing that is related to increased symptom severity in autism. The majority of studies evaluating TTV have focused on cortical processing. However, identifying whether similar atypicalities are evident in the peripheral nervous system will help isolate perturbed mechanisms in autism. The current study focuses on TTV in responses from the peripheral nervous system, specifically from electrodermal activity (EDA). We analyzed previously collected EDA data from 17 adults with autism and 19 neurotypical controls who viewed faces while being simultaneously exposed to fear (fear-induced sweat) and neutral odors. Average EDA peaks were significantly smaller and TTV was reduced in the autism group compared to controls, particularly during the fear odor condition. Amplitude and TTV were positively correlated in both groups, but the relationship was stronger in the control group. In addition, TTV was reduced in those with higher Autism Quotient scores but only for the individuals with autism. These findings confirm the existing results that atypical TTV is a key feature of autism and that it reflects symptom severity, although the smaller TTV in EDA contrasts with the previous findings of greater TTV in cortical responses. Identifying the relationship between cortical and peripheral TTV in autism is key for furthering our understanding of autism physiology. LAY SUMMARY: We compared the changes in electrodermal activity (EDA) to emotional faces over the course of repeated faces in adults with autism and their matched controls. The faces were accompanied by smelling fear-inducing odors. We found smaller and less variable responses to the faces in autism when smelling fear odors, suggesting that the peripheral nervous system may be more rigid. These findings were exaggerated in those who had more severe autism-related symptoms.

Thirty-four families participated in a laboratory visit that included continuous measurement of electrodermal activity (EDA) during a battery of naturalistic and structured parent–child, child alone, and direct testing tasks. Multiple indices of EDA were considered. Greater variability in EDA was associated with higher levels of ASD symptoms, with findings generally consistent across tasks. Intellectual functioning did not moderate the relation between EDA and ASD symptoms. Sympathetic arousal tendencies may represent an important individual difference factor for this population. Future directions and conceptualizations of EDA are discussed.

Few studies have systematically assessed the resting physiological activity in ASD with co-occurring anxiety disorders. We tested 75 participants divided in four groups: youth with ASD, with (ASD?+?Anxiety?=?22, 6F, 12.29 ± 2.83 years old) and without co-occurring anxiety (ASD Alone?=?15, 6F, 11.59 ± 2.85 years old) and compared their physiological profile with that of matched typically developing controls (TDC) with (Anxiety Alone?=?16, 6F, 11.24 ± 3.36 years old) and without co-occurring anxiety disorders (TDC?=?22, 8F, 11.88 ± 2.88 years old). Results indicated reduced sympathetic and parasympathetic activity at rest in ASD as compared to TDC youth. ASD?+?Anxiety and Anxiety Alone groups showed different sympathetic, but similar parasympathetic activity. These findings suggest that autonomic profile-based approaches may advance research, diagnosis, and treatment of ASD and anxiety.
