An Observed Assessment of Sensory Responsivity in Autism Spectrum Disorders: Associations with Diagnosis, Age, and Parent Report / Sapna RAMAPPA in Journal of Autism and Developmental Disorders, 53-10 (October 2023)

Titre : An Observed Assessment of Sensory Responsivity in Autism Spectrum Disorders: Associations with Diagnosis, Age, and Parent Report Type de document : Texte imprimé et/ou numérique Auteurs : Sapna RAMAPPA, Auteur ; Ariana ANDERSON, Auteur ; Jiwon JUNG, Auteur ; Robyn CHU, Auteur ; Kaitlin K. CUMMINGS, Auteur ; Genevieve PATTERSON, Auteur ; Nana J. OKADA, Auteur ; Shulamite A. GREEN, Auteur Article en page(s) : p.3860-3872 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Sensory features are common and impairing in autism spectrum disorder (ASD), but there are few observational sensory assessments that are valid across ages. We used the Sensory Processing 3-Dimensional (SP3-D) observed Assessment and parent-reported Inventory to examine sensory responsivity in 41 ASD and 33 typically-developing (TD) youth across 7-17 years. ASD youth had higher and more variable observed and reported sensory responsivity symptoms compared to TD, but the two measures were not correlated. Observed sensory over-responsivity (SOR) and sensory craving (SC) decreased with age in ASD, though SOR remained higher in ASD versus TD through adolescence. Results suggest that in ASD, the SP3-D Assessment can identify SOR through adolescence, and that there is value in integrating multiple sensory measures.

Titre : Atypical cerebellar functional connectivity at 9 months of age predicts delayed socio-communicative profiles in infants at high and low risk for autism Type de document : Texte imprimé et/ou numérique Auteurs : Nana J. OKADA, Auteur ; Janelle LIU, Auteur ; Tawny TSANG, Auteur ; Erin NOSCO, Auteur ; Nicole M. MCDONALD, Auteur ; Kaitlin K. CUMMINGS, Auteur ; Jiwon JUNG, Auteur ; Genevieve PATTERSON, Auteur ; Susan Y. BOOKHEIMER, Auteur ; Shulamite A. GREEN, Auteur ; Shafali S JESTE, Auteur ; Mirella DAPRETTO, Auteur Article en page(s) : p.1002-1016 Langues : Anglais (eng) Mots-clés : Autism Spectrum Disorder/diagnostic imaging Autistic Disorder Cerebellum/diagnostic imaging Communication Humans Infant Magnetic Resonance Imaging Autism spectrum disorder fMRI infancy social communication Index. décimale : PER Périodiques Résumé : BACKGROUND: While the cerebellum is traditionally known for its role in sensorimotor control, emerging research shows that particular subregions, such as right Crus I (RCrusI), support language and social processing. Indeed, cerebellar atypicalities are commonly reported in autism spectrum disorder (ASD), a neurodevelopmental disorder characterized by socio-communicative impairments. However, the cerebellum's contribution to early socio-communicative development remains virtually unknown. METHODS: Here, we characterized functional connectivity within cerebro-cerebellar networks implicated in language/social functions in 9-month-old infants who exhibit distinct 3-year socio-communicative developmental profiles. We employed a data-driven clustering approach to stratify our sample of infants at high (n=82) and low (n=37) familial risk for ASD into three cohorts-Delayed, Late-Blooming, and Typical-who showed unique socio-communicative trajectories. We then compared the cohorts on indices of language and social development. Seed-based functional connectivity analyses with RCrusI were conducted on infants with fMRI data (n=66). Cohorts were compared on connectivity estimates from a-priori regions, selected on the basis of reported coactivation with RCrusI during language/social tasks. RESULTS: The three trajectory-based cohorts broadly differed in social communication development, as evidenced by robust differences on numerous indices of language and social skills. Importantly, at 9months, the cohorts showed striking differences in cerebro-cerebellar circuits implicated in language/social functions. For all regions examined, the Delayed cohort exhibited significantly weaker RCrusI connectivity compared to both the Late-Blooming and Typical cohorts, with no significant differences between the latter cohorts. CONCLUSIONS: We show that hypoconnectivity within distinct cerebro-cerebellar networks in infancy predicts altered socio-communicative development before delays overtly manifest, which may be relevant for early detection and intervention. As the cerebellum is implicated in prediction, our findings point to probabilistic learning as a potential intermediary mechanism that may be disrupted in infancy, cascading into alterations in social communication.
