Event-related potentials to repeated speech in 9-month-old infants at risk for autism spectrum disorder / A. SEERY in Journal of Neurodevelopmental Disorders, 6-1 (December 2014)
[article]
Titre : Event-related potentials to repeated speech in 9-month-old infants at risk for autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : A. SEERY, Auteur ; Helen TAGER-FLUSBERG, Auteur ; C. A. NELSON, Auteur Article en page(s) : p.43 Langues : Anglais (eng) Mots-clés : Auditory evoked potentials Autism spectrum disorders Endophenotype Event-related potentials Infancy Language Speech processing Index. décimale : PER Périodiques Résumé : BACKGROUND: Atypical neural responses to repeated auditory and linguistic stimuli have been reported both in individuals with autism spectrum disorder (ASD) and their first-degree relatives. Recent work suggests that the younger siblings of children with ASD have atypical event-related potentials (ERPs) to repeated tones at 9 months of age; however, the functional significance is unclear, and it is unknown whether this atypicality is also present in response to linguistic stimuli. METHODS: We analyzed ERPs to repetitive and deviant consonant-vowel stimuli at 9 months in 35 unaffected high-risk-for-autism (HRA) infant siblings of children with ASD and 45 low-risk control (LRC) infants. We examined a positive component, the P150, over frontal and central electrode sites and investigated the relationships between this component and later behavior. RESULTS: Over frontal electrodes, HRA infants had larger-amplitude ERPs to repetitions of the standard than LRC infants, whereas ERPs to the deviant did not differ between HRA and LRC infants. Furthermore, for HRA infants, the amplitude of ERPs to the standards was positively correlated with later language ability. CONCLUSIONS: Our work suggests that atypical ERPs to repeated speech during infancy are a possible endophenotype of ASD but that this atypicality is associated with beneficial, rather than disordered, language development. Potential mechanisms driving these relationships and implications for development are discussed.

Titre : Early and late auditory event-related potentials in cognitively high functioning male adolescents with autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Stein ANDERSSON, Auteur ; Maj-Britt POSSERUD, Auteur ; Astri J. LUNDERVOLD, Auteur Article en page(s) : p.815-823 Langues : Anglais (eng) Mots-clés : Event-related potentials Autism spectrum disorders sensory processing Index. décimale : PER Périodiques Résumé : Event-related potentials (ERP) studies have offered diverging results in characterizing the basic nature of abnormal sensory processing and discrimination in autism spectrum disorders (ASDs). In the present study we report duration mismatch negativity (MMN) and later ERP components (P3a and P3b) derived from auditory odd-ball paradigms in a homogenous sample of cognitively high functioning male adolescents with ASD. We find significantly reduced frontal and temporal MMN amplitudes and no differences in P3a or P3b amplitudes or latencies compared to controls. These findings are in contrast to recent studies reporting enhanced ERP amplitudes to auditory stimuli, and are more in support of a weakened automatic auditory sensory processing as being central to the abnormal auditory behavioral responses commonly encountered in ASD.

Event-related potentials elicited by task-irrelevant sounds were used to elucidate neural correlates of auditory processing and associations with three common sensory response patterns (hyperresponsiveness; hyporesponsiveness; sensory seeking). Twenty-eight children with autism and 39 typically developing children (4–12 year-olds) completed an auditory oddball paradigm. Results revealed marginally attenuated P1 and N2 to standard tones and attenuated P3a to novel sounds in autism versus controls. Exploratory analyses suggested that within the autism group, attenuated N2 and P3a amplitudes were associated with greater sensory seeking behaviors for specific ranges of P1 responses. Findings suggest that attenuated early sensory as well as later attention-orienting neural responses to stimuli may underlie selective sensory features via complex mechanisms.

However, the involvement of successive memory processes in the profile of episodic memory in ASD needs more study. Here, we used event-related potentials (ERP) to investigate the time course of episodic recollection with an associative recognition paradigm with picture pairs. Twenty-two participants with ASD and 32 with typical development (TD), all right-handed, were included. Behavioral results confirmed difficulties in correctly recognizing identical pairs in the ASD relative to TD group. We found an unexpected amplitude decrement on the P2 (220-270?msec) and FN400 (350-470?msec) potentials, suggesting diminished priming and familiarity effects in the ASD relative to TD group. However, ERP data revealed that the recognition of associative information relies on the same electrophysiological process (old/new effect in the 600-700-msec late positive component) in ASD participants as in TD ones, with a parietal extension in the ASD group. These results suggest that the electrophysiological processes of associative recognition are qualitatively similar in individuals with and without ASD but may differ quantitatively. This difference may be driven by the reduced early processing of picture pairs that may in turn lead to their diminished integration into the semantic memory system, being partially compensated by a greater involvement of associative memory during the recollection process. Other studies would be useful to go further in identifying these cognitive processes involved in atypical recognition in ASD and their neural substrates.

However, the cognitive processing mechanisms of executive dysfunction have not been addressed. In the present study, the endogenous Posner paradigm task was administered to 15 children with ASD and 16 typically developing (TD) children to simultaneously investigate and compare the behavioral performance and event-related potentials (ERPs) measures. Children with ASD showed slower reaction time in the incongruent condition but did not significantly differ in the overall conditions and in response accuracy as compared to TD children. The ASD group also exhibited significant impairment on measures of inhibitory control. In terms of ERPs regarding early and late inhibition, there were no significant differences found with regard to N2 latency, N2 amplitude, and P3 amplitude in children with ASD relative to TD children, but the ASD group manifested prolonged latency on the P3 component to target stimuli, especially in the incongruent condition, which is indicative of slow and inefficient stimulus classification speed as compared to TD children.
