Few studies have examined factors associated with parental stress in early childhood. Even fewer have investigated the simultaneous influence of sociodemographic, clinical, and developmental variables on parental stress. We examined factors associated with stress in parents of young children with ASD. Multiple regression models were used to test for associations between socioeconomic indices, developmental measures, and parental stress. Externalizing behaviors, communication, and socialization skills accounted for variance in parental stress, controlling for ASD diagnosis. Results highlight the importance of interventions aimed at reducing externalizing behaviors in young children as well as addressing stress in caregivers of children with ASD.

Functional connectivity patterns differ as a function of co-occurring attentional problems in preschoolers with autism / Alex BOXBERGER in Journal of Neurodevelopmental Disorders, 17 (2025)  

Public ISBD [article]  inJournal of Neurodevelopmental Disorders > 17 (2025) Titre : Functional connectivity patterns differ as a function of co-occurring attentional problems in preschoolers with autism Type de document : texte imprimé Auteurs : Alex BOXBERGER, Auteur ; Bosi CHEN, Auteur ; Lindsay OLSON, Auteur ; Michaela CORDOVA, Auteur ; Judy MAHMALJI, Auteur ; Adriana RIOS, Auteur ; Annika C. LINKE, Auteur ; Inna FISHMAN, Auteur Langues : Anglais (eng) Mots-clés : Humans  Child, Preschool  Male  Female  Autism Spectrum Disorder/physiopathology/diagnostic imaging/complications  Attention Deficit Disorder with Hyperactivity/physiopathology/diagnostic  imaging/complications/epidemiology  Magnetic Resonance Imaging  Infant  Connectome  Brain/physiopathology/diagnostic imaging  Nerve Net/physiopathology/diagnostic imaging  Child Development/physiology  Attention  Autism spectrum  Early development  Functional MRI  Network connectivity  was approved by the institutional review boards of the University of California  San Diego and San Diego State University (Joint Review IRB #151091).

Index. décimale : PER Périodiques Résumé : BACKGROUND: Symptoms of attention-deficit/hyperactivity disorder (ADHD) are common in children with autism spectrum disorder (ASD), and are associated with greater developmental challenges, poorer clinical outcomes, and alterations in functional connectivity (FC) of the brain. However, despite the consensus that ASD and other neurodevelopmental conditions emerge early in life, little is known about the trajectories of brain and behavioral development during the first years of life in children with ASD and co-occurring attention problems (AP). METHODS: In a sample of 122 young children (ages 1.5-5 years) with and without ASD, we examined whether toddlers and preschoolers with ASD and co-occurring AP already differ from peers with ASD without co-occurring AP on adaptive and developmental skills, ASD symptoms, and FC of the frontoparietal and salience networks, which have been previously linked to ADHD symptoms in older children with ASD and ADHD. RESULTS: Results of general linear model analyses revealed lower developmental and adaptive skills across multiple domains in children with ASD and elevated AP compared with their peers with lower AP, despite equivalent levels of ASD symptoms. Further, children with ASD and elevated AP showed reduced FC within the frontoparietal network (p = .027), between the frontoparietal and language networks (p = .004), and the frontoparietal and default mode networks (p = .046) in comparison to their peers with lower AP. No group differences in FC of the salience network were observed (all p > .05). CONCLUSIONS: These findings provide evidence that neurodevelopmental and behavioral differences in children with ASD and co-occurring AP emerge very early in life, before a reliable diagnosis of ADHD is typically made. Specifically, these results demonstrate that early inattention symptoms are associated with unique connectivity patterns in executive circuitry as early as the first years of life in toddlers and preschoolers with ASD, likely contributing to the phenotypic and neural heterogeneity recognized in autism. Thus, our results underscore the importance of considering co-occurring conditions early in developmental research and clinical care, as further understanding these trajectories can inform early interventions during the critical time period when they have the greatest potential for positive impact.

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)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 62-2 (February 2021) . - p.160-170 Titre : Greater functional connectivity between sensory networks is related to symptom severity in toddlers with autism spectrum disorder Type de document : texte imprimé 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.
