Exploring brainstem auditory evoked potentials and mental development index as early indicators of autism spectrum disorders in high-risk infants / Xiaoyan WANG in Autism Research, 15-11 (November 2022)

Titre : Exploring brainstem auditory evoked potentials and mental development index as early indicators of autism spectrum disorders in high-risk infants Type de document : Texte imprimé et/ou numérique Auteurs : Xiaoyan WANG, Auteur ; Xianming CARROLL, Auteur ; Ping ZHANG, Auteur ; Jean-Baptist DU PREL, Auteur ; Hong WANG, Auteur ; Haiqing XU, Auteur ; Sandra LEEPER-WOODFORD, Auteur Article en page(s) : p.2012-2025 Langues : Anglais (eng) Mots-clés : Infant Humans Evoked Potentials, Auditory, Brain Stem/physiology Autism Spectrum Disorder/diagnosis Mass Screening Odds Ratio China Evoked Potentials, Auditory absolute latencies autism spectrum disorders brainstem auditory evoked potential infants interpeak latencies mental development index Index. décimale : PER Périodiques Résumé : This study of infants from Hubei Province, China examined brainstem auditory evoked potentials (BAEP) and mental development index (MDI) as possible early indicators associated with autism spectrum disorders (ASD). The 34 ASD cases and 102 controls who had recovered from perinatal conditions were matched for age, sex, gestational age, birth weight and maternal age. BAEP absolute latencies (AL) I, III, V and interpeak latencies (IPL) I-III, III-V, I-V were compared in ASD cases and controls at ages 1, 3 and 6Â months. MDI scores were compared in these infants from 1Â month to 2 years old. Multiple logistic regression analysis was performed to test associations among ASD, BAEP and MDI. Results showed BAEP AL I, V and IPL III-V prolonged in the ASD group (p < 0.001), and MDI scores in ASD cases sharply declining from 12 to 24 months (p < 0.001). Regression analysis revealed odds ratios (OR) indicating that ASD was likely associated with abnormal values of BAEP AL I at 1 and 3Â months (OR(AL I) : 4.27; OR(AL I) : 4.13), and AL V at 6Â months (OR(AL V) : 7.85). Lower MDI scores (MDI < 80) in infants at 1, 3, and 6Â months were likely associated with ASD (OR(MDI) : 2.58; OR(MDI) : 3.83; OR(MDI) : 4.87). These data show that abnormal BAEP values and low MDI scores are independent factors associated with ASD, and that monitoring of BAEP and MDI during infancy might facilitate screening for ASD development.

Titre : Individuals With Autism Have No Detectable Deficit in Neural Markers of Prediction Error When Presented With Auditory Rhythms of Varied Temporal Complexity Type de document : Texte imprimé et/ou numérique Auteurs : Emily J. KNIGHT, Auteur ; Leona OAKES, Auteur ; Susan L. HYMAN, Auteur ; Edward G. FREEDMAN, Auteur ; John J. FOXE, Auteur Article en page(s) : p.2058-2072 Langues : Anglais (eng) Mots-clés : auditory perceptual disorders autism spectrum disorder communication disorders electroencephalography evoked potentials, auditory mismatch negativity Index. décimale : PER Périodiques Résumé : The brain's ability to encode temporal patterns and predict upcoming events is critical for speech perception and other aspects of social communication. Deficits in predictive coding may contribute to difficulties with social communication and overreliance on repetitive predictable environments in individuals with autism spectrum disorder (ASD). Using a mismatch negativity (MMN) task involving rhythmic tone sequences of varying complexity, we tested the hypotheses that (1) individuals with ASD have reduced MMN response to auditory stimuli that deviate in presentation timing from expected patterns, particularly as pattern complexity increases and (2) amplitude of MMN signal is inversely correlated with level of impairment in social communication and repetitive behaviors. Electroencephalography was acquired as individuals (age 6-21?years) listened to repeated five-rhythm tones that varied in the Shannon entropy of the rhythm across three conditions (zero, medium-1 bit, and high-2 bit entropy). The majority of the tones conformed to the established rhythm (standard tones); occasionally the fourth tone was temporally shifted relative to its expected time of occurrence (deviant tones). Social communication and repetitive behaviors were measured using the Social Responsiveness Scale and Repetitive Behavior Scale-Revised. Both neurotypical controls (n = 19) and individuals with ASD (n = 21) show stepwise decreases in MMN as a function of increasing entropy. Contrary to the result forecasted by a predictive coding hypothesis, individuals with ASD do not differ from controls in these neural mechanisms of prediction error to auditory rhythms of varied temporal complexity, and there is no relationship between these signals and social communication or repetitive behavior measures. LAY SUMMARY: We tested the idea that the brain's ability to use previous experience to influence processing of sounds is weaker in individuals with autism spectrum disorder (ASD) than in neurotypical individuals. We found no difference between individuals with ASD and neurotypical controls in brain wave responses to sounds that occurred earlier than expected in either simple or complex rhythms. There was also no relationship between these brain waves and social communication or repetitive behavior scores.
