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)

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.

Play in Relation to Autism Traits in Young Children at Elevated Likelihood for Autism Spectrum Disorder / Floor MOERMAN in Journal of Autism and Developmental Disorders, 53-4 (April 2023)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 53-4 (April 2023) . - p.1413-1430 Titre : Play in Relation to Autism Traits in Young Children at Elevated Likelihood for Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Floor MOERMAN, Auteur ; Petra WARREYN, Auteur ; Ellen DEMURIE, Auteur ; Sofie BOTERBERG, Auteur ; Julie VERMEIRSCH, Auteur ; Chloè BONTINCK, Auteur ; Eva BRUYNEEL, Auteur ; Marjolein MUÈS, Auteur ; Liedewij VERHAEGHE, Auteur ; Herbert ROEYERS, Auteur ; Team BABY STUDY, Auteur Article en page(s) : p.1413-1430 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Play of younger siblings of children with autism spectrum disorder (ASD) (siblings; n=44), very preterm children (preterms; n=44), and children at typical likelihood for ASD (n=36) was observed at 24 months. Children with ASD and atypical development engaged less in spontaneous (pre-)symbolic play than typically developing children. Total duration of spontaneous and elicited (pre-)symbolic play was associated with later ASD traits in siblings. However, no association between most play variables and ASD traits was found in preterms. This suggests possible different ASD-trajectories between siblings and preterms. Thus, spontaneous (pre-)symbolic play may be indicative of developmental challenges across several populations, and results highlight the need to move beyond studying only siblings in order to broaden our understanding of ASD.

Predictors of synchronized verbalizations in mothers of children at elevated likelihood of autism / Ines BRYS ; Lotte VAN ESCH ; Melinda MADAREVIC ; Floor MOERMAN ; Lyssa DE VRIES ; Petra WARREYN ; Jean STEYAERT ; Herbert ROEYERS ; Ilse NOENS in Research in Autism, 125 (July 2025)

Yet, the relationship, between parents" synchronized verbalizations and child development is almost. exclusively studied in a one-directional manner. We therefore investigated the, predictive value of child development (i.e. language and cognitive abilities and autism, research diagnosis) on parents" synchronized verbalizations. Methods We observed, 93 mother-child dyads containing children at elevated likelihood of autism (i.e. siblings, and preterms). Child language and cognitive abilities were assessed around 10, months, parenting behaviors around 14 months, and best estimate research diagnoses, were given around 36 months. We ran hierarchical linear regression models to predict, (a) all synchronized verbalizations and (b) synchronized verbalizations which were, posed in a non-directive manner. Results Early language abilities, but not cognitive, abilities or autism research diagnosis predicted mothers" synchronized verbalizations. Results were similar for both operationalizations of synchronized verbalizations (i.e. all and non-directive). Our findings indicate that the current uni-directional view might need to be expanded to a more transactional model.
