Greater functional connectivity between sensory networks is related to symptom severity in toddlers with autism spectrum disorder / Bosi CHEN in Journal of Child Psychology and Psychiatry, 62-2 (February 2021)
[article]
Titre : Greater functional connectivity between sensory networks is related to symptom severity in toddlers with autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Bosi CHEN, Auteur ; Annika LINKE, Auteur ; Lindsay OLSON, Auteur ; Cynthia IBARRA, Auteur ; Sarah REYNOLDS, Auteur ; Ralph-Axel MULLER, Auteur ; Mikaela KINNEAR, Auteur ; Inna FISHMAN, Auteur Année de publication : 2021 Article en page(s) : p.160-170 Langues : Anglais (eng) Mots-clés : Brain networks autism spectrum disorders early childhood functional connectivity neuroimaging Index. décimale : PER Périodiques Résumé : BACKGROUND: Symptoms of autism spectrum disorder (ASD) emerge in the first years of life. Yet, little is known about the organization and development of functional brain networks in ASD proximally to the symptom onset. Further, the relationship between brain network connectivity and emerging ASD symptoms and overall functioning in early childhood is not well understood. METHODS: Resting-state fMRI data were acquired during natural sleep from 24 young children with ASD and 23 typically developing (TD) children, aged 17-45 months. Intrinsic functional connectivity (iFC) within and between resting-state functional networks was derived with independent component analysis (ICA). RESULTS: Increased iFC between visual and sensorimotor networks was found in young children with ASD compared to TD participants. Within the ASD group, the degree of overconnectivity between visual and sensorimotor networks was associated with greater autism symptoms. Age-related weakening of the visual-auditory between-network connectivity was observed in the ASD but not the TD group. CONCLUSIONS: Taken together, these results provide evidence for disrupted functional network maturation and differentiation, particularly involving visual and sensorimotor networks, during the first years of life in ASD. The observed pattern of greater visual-sensorimotor between-network connectivity associated with poorer clinical outcomes suggests that disruptions in multisensory brain circuitry may play a critical role for early development of behavioral skills and autism symptomatology in young children with ASD.

OLSON, Auteur ; Lisa E. MASH, Auteur ; Annika LINKE, Auteur ; Christopher H.

Index. décimale : PER Périodiques Résumé : We investigated whether children and adolescents with autism spectrum disorders show sex-specific patterns of brain function (using functional magnetic resonance imaging) that are well documented in typically developing males and females. We found, unexpectedly, that boys and girls with autism do not differ in their brain functional connectivity, whereas typically developing boys and girls showed differences in a brain network involved in thinking about self and others (the default mode network). Results suggest that autism may be characterized by a lack of brain sex differentiation.
