Autonomic and Electrophysiological Evidence for Reduced Auditory Habituation in Autism / T. K. GANDHI in Journal of Autism and Developmental Disorders, 51-7 (July 2021)
[article]
Titre : Autonomic and Electrophysiological Evidence for Reduced Auditory Habituation in Autism Type de document : Texte imprimé et/ou numérique Auteurs : T. K. GANDHI, Auteur ; K. TSOURIDES, Auteur ; N. SINGHAL, Auteur ; A. CARDINAUX, Auteur ; W. JAMAL, Auteur ; D. PANTAZIS, Auteur ; M. KJELGAARD, Auteur ; P. SINHA, Auteur Article en page(s) : p.2218-2228 Langues : Anglais (eng) Mots-clés : Adolescent Autistic Disorder/physiopathology Case-Control Studies Child Female Galvanic Skin Response Habituation, Psychophysiologic/physiology Humans Magnetoencephalography Male Perception/physiology Young Adult Autism Gsr Habituation Hypersensitivities Meg Index. décimale : PER Périodiques Résumé : It is estimated that nearly 90% of children on the autism spectrum exhibit sensory atypicalities. What aspects of sensory processing are affected in autism? Although sensory processing can be studied along multiple dimensions, two of the most basic ones involve examining instantaneous sensory responses and how the responses change over time. These correspond to the dimensions of 'sensitivity' and 'habituation'. Results thus far have indicated that autistic individuals do not differ systematically from controls in sensory acuity/sensitivity. However, data from studies of habituation have been equivocal. We have studied habituation in autism using two measures: galvanic skin response (GSR) and magneto-encephalography (MEG). We report data from two independent studies. The first study, was conducted with 13 autistic and 13 age-matched neurotypical young adults and used GSR to assess response to an extended metronomic sequence. The second study involved 24 participants (12 with an ASD diagnosis), different from those in study 1, spanning the pre-adolescent to young adult age range, and used MEG. Both studies reveal consistent patterns of reduced habituation in autistic participants. These results suggest that autism, through mechanisms that are yet to be elucidated, compromises a fundamental aspect of sensory processing, at least in the auditory domain. We discuss the implications for understanding sensory hypersensitivities, a hallmark phenotypic feature of autism, recently proposed theoretical accounts, and potential relevance for early detection of risk for autism.

In present study the habituation to standard tones following deviants and the auditory discriminative processes were examined in two conditions: electronic and human sounds, in a sample of 16 ASD children. ASD children presented a reduced habituation in the P1 component and a decrease in the amplitude of the mismatch negativity indicating a lower auditory discrimination with respect to controls. MMN amplitude was related to sensory sensitivity. Results suggest an increased activation to repeatedly auditory stimulus and a poor auditory discrimination, for both: electronic and human sounds with consequences on the impaired sensory behavior of ASD subjects.

As underlying factors are unknown, we examined whether ASD adults (NASD = 33; NTypically Developing = 31; 25-45 years; IQ > 70): (1) habituated slower to auditory stimuli; (2) had lower auditory detection thresholds; and (3) whether these mechanisms related to self-reported auditory sensitivities. Two auditory stimuli (tone, siren) were repeated, whilst skin conductance responses were recorded to measure habituation. Detection thresholds were measured by stepwise reductions in tone volume. We found no evidence in favor of our hypotheses, but ASD adults did rate the auditory stimuli as more arousing. Based on explorative analyses, we argue that studying the strength of physiological responses to auditory stimuli is needed to understand auditory sensitivities.

This study investigated habituation to fearful faces and houses in ASD and whether fMRI measures of brain activity discriminate between ASD and typically developing (TD) controls. Two identical fMRI runs presenting masked fearful faces, houses, and scrambled images were collected. We found significantly slower fMRI responses to fearful faces but not houses in ASD. In addition, the pattern of slow to emerge amygdala activation to faces had robust discriminability [ASD vs. TD; area under the curve (AUC) = .852, p < .001]. In contrast, habituation to houses had no predictive value (AUC = .573, p = .365). Amygdala habituation to emotional faces may be useful for quantifying risk in ASD.

Effects of ELA on brain function are well recognized, and emerging evidence suggests that caregivers may influence how environmental stressors impact children?s brain function. We investigated the hypothesis that positive interaction between mother and child can buffer against ELA effects on children?s neural responses to threat, and related symptoms. N = 53 mother-child pairs (children ages 8-14 years) were recruited from an urban population at high risk for violence exposure. Maternal caregiving was measured using the Parenting Questionnaire and in a cooperation challenge task. Children viewed fearful and neutral face stimuli during functional magnetic resonance imaging. Children who experienced greater violence at home showed amygdala sensitization, whereas children experiencing more school and community violence showed amygdala habituation. Sensitization was in turn linked with externalizing symptoms. However, maternal warmth was associated with a normalization of amygdala sensitization in children, and fewer externalizing behaviors prospectively up to 1 year later. Findings suggested that the effects of violence exposure on threat-related neural circuitry depend on trauma context (inside or outside the home) and that primary caregivers can increase resilience.
