An ERP study Type de document : Texte imprimé et/ou numérique Auteurs : Alessandra PIATTI, Auteur ; Sara VAN DER PAELT, Auteur ; Petra WARREYN, Auteur ; Herbert ROEYERS, Auteur Article en page(s) : 101805 Langues : Anglais (eng) Mots-clés : Auditory oddball  MMN  P3a  ASD  Developmental delay  Neural adaptation Index. décimale : PER Périodiques Résumé : Background Sound perception in autism spectrum disorder (ASD) is usually at typical levels, even when auditory stimuli carry a social value, as it is the case for speech. Nevertheless, orienting to sounds in a speech context might be atypical in some individuals with ASD, which in ERP studies is reflected by a diminished P3a component. As P3 values and cognitive abilities seem to be inversely related under some circumstances, the current study investigates whether diminished attentional orienting to sounds in speech is equally observable in children with ASD with and without developmental delay (DD). Method Children with typical development (TD, n = 17) or ASD, with or without comorbid DD (ASD/DD, n = 22, and ASD/noDD, n = 12), aged 1.5 through 4 years took part in a passive auditory oddball task while EEG data were recorded. The paradigm consisted in the presentation of two deviant stimuli (one vowel sound and one complex tone) either in a speech or in a non-speech context. Results We found overall more negative MMN voltages in both ASD groups compared to TD. For P3a mean voltages, we found an attenuated response in children ASD/noDD when deviant tones were presented in speech, but not in other conditions. Children with ASD/DD did not differ from TD in P3a mean voltages. Conclusion Atypical speech sound processing might be more accentuated in children with ASD/noDD than in their peers with comorbid DD. This finding is interpreted within the theoretical framework of neural adaptation.

Atypical brain network development of infants at elevated likelihood for autism spectrum disorder during the first year of life / Fen ZHANG in Autism Research, 15-12 (December 2022)  

Public ISBD [article]  inAutism Research > 15-12 (December 2022) . - p.2223-2237 Titre : Atypical brain network development of infants at elevated likelihood for autism spectrum disorder during the first year of life Type de document : Texte imprimé et/ou numérique Auteurs : Fen ZHANG, Auteur ; Floor MOERMAN, Auteur ; Haijing NIU, Auteur ; Petra WARREYN, Auteur ; Herbert ROEYERS, Auteur Article en page(s) : p.2223-2237 Langues : Anglais (eng) Mots-clés : Infant  Humans  Autism Spectrum Disorder  Neurodevelopmental Disorders  Brain/diagnostic imaging  Phenotype  autism spectrum disorder  brain network  functional connectivity  functional near-infrared spectroscopy  neurodevelopmental disorder Index. décimale : PER Périodiques Résumé : Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by behavioral features that appear early in life. Although studies have shown that atypical brain functional and structural connectivity are associated with these behavioral traits, the occurrence and initial alterations of brain networks have not been fully investigated. The current study aimed to map early brain network efficiency and information transferring in infants at elevated likelihood (EL) compared to infants at typical likelihood (TL) for ASD in the first year of life. This study used a resting-state functional near-infrared spectroscopy (fNIRS) approach to obtain the length and strength of functional connections in the frontal and temporal areas in 45 5-month-old and 38 10-month-old infants. Modular organization and small-world properties were detected in both EL and TL infants at 5 and 10 months. In 5-month-old EL infants, local and nodal efficiency were significantly greater than age-matched TL infants, indicating overgrown local connections. Furthermore, we used a support vector machine (SVM) model to classify infants with or without EL based on the obtained global properties of the network, achieving an accuracy of 77.6%. These results suggest that infants with EL for ASD exhibit inefficiencies in the organization of brain networks during the first year of life.

Can Child Care Workers Contribute to the Early Detection of Autism Spectrum Disorders? A Comparison Between Screening Instruments with Child Care Workers Versus Parents as Informants / Mieke DEREU in Journal of Autism and Developmental Disorders, 42-5 (May 2012)

Only few studies compare the discriminative power of these instruments in the same sample. In particular comparisons of instruments that use different informants are scarce in young children. The current study compared the discriminant ability of the Checklist for Early Signs of Developmental Disorders (CESDD) filled out by child care workers with that of frequently used parent questionnaires in a sample of 357 children between 5.57 and 48.13 months old who showed signs of ASD or language delay. The discriminant power of the CESDD was as good as that of parent questionnaires. Therefore, inclusion of child care workers in the early detection of ASD seems promising.

Exploring individual trajectories of social communicative development in toddlers at risk for autism spectrum disorders / Mieke DEREU in Research in Autism Spectrum Disorders, 6-3 (July-September 2012)

The main objective was to explore these trajectories in a sample of children at risk for ASD between the ages of 2 and 4 years. After screening positive for ASD, 17 children were prospectively followed with 6-monthly assessments of social communicative skills and general development. During this study, 9 children were diagnosed with ASD. Results showed that there was growth in imitation skills and in pretend play ability. Also, a slightly increased amount of initiation of joint attention was noted. However, the quality of joint attention behaviours did not significantly improve and growth rates did not significantly differ between children with ASD and non-ASD cases. There was a great intra-individual variability, especially in the performances on the imitation tasks. Also interindividual variability was apparent: some children with ASD showed a delayed development of imitation or pretend play, whereas others had a more clearly deviant developmental profile. The importance of looking at individual trajectories and variability in the study of social communicative development in children with ASD is discussed.
