KEEHN, Auteur Article en page(s) : p.2946-2955 Langues : Anglais (eng) Mots-clés : Attentional disengagement  Autism  Infant siblings  Social orienting  Touch Index. décimale : PER Périodiques Résumé : Atypical response to tactile input is associated with greater socio-communicative impairments in individuals with autism spectrum disorder (ASD). The current study examined overt orienting to caregiver-initiated touch in 12-month-olds at high risk for ASD (HRA) with (HRA+) and without (HRA-) a later diagnosis of ASD compared to low-risk comparison infants. Findings indicate that infants that go on to receive a diagnosis of ASD may more frequently fail to shift their attention in response to caregiver touch and when they do, they may be more likely to orient away from touch. Additionally, failure to respond to touch predicts ADOS severity scores at outcome suggesting that atypical response to touch may be an early indicator of autism severity.

Brief Report: Parents' Declarative Use of Deictic Gestures Predict Vocabulary Development in Infants at High and Low Risk for Autism Spectrum Disorder / B. CHOI in Journal of Autism and Developmental Disorders, 52-2 (February 2022)

We found that parents in the three groups produced similar numbers of declarative and imperative gestures during a 10-minute parent-child interaction in the lab at 12 months and that 12-month parental declarative gesture use was significantly, positively associated with children's 36-month vocabulary scores. Encouraging parental use of declarative gestures with infants could have important implications for language development.

Among high-risk siblings (with and without ASD), as well as among 583 low-risk controls, girls exhibited higher performance on the Mullen Scales of Early Learning, as well as lower restricted and repetitive behavior severity scores on the Autism Diagnostic Observation Schedule (ADOS) than boys. That is, female-favoring sex differences in developmental performance and autism traits were evident among low-risk and non-ASD high-risk children, as well as those with ASD. Constantino (Mol Autism) suggests that sex differences in categorical ASD outcomes in Messinger et al. should be understood as a female protective effect. We are receptive to Constantino's (Mol Autism) suggestion, and propose that quantitative sex differences in autism-related features are keys to understanding this female protective effect.

Deletion and duplication of 16p11.2 are associated with opposing effects on visual evoked potential amplitude / J. J. LEBLANC in Molecular Autism, 7 (2016)  

Public ISBD [article]  inMolecular Autism > 7 (2016) . - 30p. Titre : Deletion and duplication of 16p11.2 are associated with opposing effects on visual evoked potential amplitude Type de document : Texte imprimé et/ou numérique Auteurs : J. J. LEBLANC, Auteur ; C. A. NELSON, Auteur Article en page(s) : 30p. Langues : Anglais (eng) Mots-clés : Adolescent  Child  Child, Preschool  Chromosomes, Human, Pair 16/genetics  DNA Copy Number Variations  Developmental Disabilities/diagnosis/physiopathology  Electroencephalography  Evoked Potentials, Visual/physiology  Female  Gene Deletion  Gene Duplication  Humans  Male  Visual Cortex/diagnostic imaging  16p11.2 copy number variation  Visual cortex  Visual evoked potential Index. décimale : PER Périodiques Résumé : BACKGROUND: Duplication and deletion of the chromosomal region 16p11.2 cause a broad range of impairments, including intellectual disability, language disorders, and sensory symptoms. However, it is unclear how changes in 16p11.2 dosage affect cortical circuitry during development. The aim of this study was to investigate whether the visual evoked potential (VEP) could be used as a noninvasive quantitative measure of cortical processing in children with 16p11.2 copy number variation. METHODS: Pattern-reversal VEPs were successfully recorded in 19 deletion carriers, 9 duplication carriers, and 13 typically developing children between the ages of 3 and 14 years. The stimulus was a black and white checkerboard (60') that reversed contrast at 2 Hz. VEP responses were extracted from continuous EEG recorded using a high-density elasticized electrode net. RESULTS: Quantitative analysis of the VEP waveform revealed that, relative to controls, deletion carriers displayed increased amplitude and duplication carriers displayed diminished amplitude. Latencies of the VEP waveform components were unaffected by 16p11.2 status. P1 amplitude did not correlate with age, IQ, or head circumference. CONCLUSIONS: The results of this study suggest that recording VEP is a useful method to assay cortical processing in children with 16p11.2 copy number variation. There is a gene dosage-dependent effect on P1 amplitude that merits further investigation. The VEP is directly translatable to animal models, offering a promising way to probe the neurobiological mechanisms underlying cortical dysfunction in this developmental disorder.

Development of fine motor skills is associated with expressive language outcomes in infants at high and low risk for autism spectrum disorder / B. CHOI in Journal of Neurodevelopmental Disorders, 10-1 (December 2018)  

Public ISBD [article]  inJournal of Neurodevelopmental Disorders > 10-1 (December 2018) . - 14 p. Titre : Development of fine motor skills is associated with expressive language outcomes in infants at high and low risk for autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : B. CHOI, Auteur ; K. A. LEECH, Auteur ; Helen TAGER-FLUSBERG, Auteur ; C. A. NELSON, Auteur Année de publication : 2018 Article en page(s) : 14 p. Langues : Anglais (eng) Mots-clés : Autism  Early development  Expressive language  Fine motor skills  Infant siblings Index. décimale : PER Périodiques Résumé : BACKGROUND: A growing body of research suggests that fine motor abilities are associated with skills in a variety of domains in both typical and atypical development. In this study, we investigated developmental trajectories of fine motor skills between 6 and 24 months in relation to expressive language outcomes at 36 months in infants at high and low familial risk for autism spectrum disorder (ASD). METHODS: Participants included 71 high-risk infants without ASD diagnoses, 30 high-risk infants later diagnosed with ASD, and 69 low-risk infants without ASD diagnoses. As part of a prospective, longitudinal study, fine motor skills were assessed at 6, 12, 18, and 24 months of age and expressive language outcomes at 36 months using the Mullen Scales of Early Learning. Diagnosis of ASD was determined at the infant's last visit to the lab (18, 24, or 36 months) using the Autism Diagnostic Observation Schedule. RESULTS: Hierarchical linear modeling revealed that high-risk infants who later developed ASD showed significantly slower growth in fine motor skills between 6 and 24 months, compared to their typically developing peers. In contrast to group differences in growth from age 6 months, cross-sectional group differences emerged only in the second year of life. Also, fine motor skills at 6 months predicted expressive language outcomes at 3 years of age. CONCLUSIONS: These results highlight the importance of utilizing longitudinal approaches in measuring early fine motor skills to reveal subtle group differences in infancy between ASD high-risk and low-risk infant populations and to predict their subsequent language outcomes.
