Association between spectral electroencephalography power and autism risk and diagnosis in early development / S. HUBERTY in Autism Research, 14-7 (July 2021)

Infants who are at high familial risk for, and later diagnosed with ASD, show atypical activity in multiple electroencephalography (EEG) oscillatory measures. However, infant-sibling studies are often constrained by small sample sizes. We used the International Infant EEG Data Integration Platform, a multi-site dataset with 432 participants, including 222 at high-risk for ASD, from whom repeated measurements of EEG were collected between the ages of 3-36?months. We applied a latent growth curve model to test whether familial risk status predicts developmental trajectories of spectral power across the first 3?years of life, and whether these trajectories predict ASD outcome. Change in spectral EEG power in all frequency bands occurred during the first 3?years of life. Familial risk, but not a later diagnosis of ASD, was associated with reduced power at 3?months, and a steeper developmental change between 3 and 36?months in nearly all absolute power bands. ASD outcome was not associated with absolute power intercept or slope. No associations were found between risk or outcome and relative power. This study applied an analytic approach not used in previous prospective biomarker studies of ASD, which was modeled to reflect the temporal relationship between genetic susceptibility, brain development, and ASD diagnosis. Trajectories of spectral power appear to be predicted by familial risk; however, spectral power does not predict diagnostic outcome above and beyond familial risk status. Discrepancies between current results and previous studies are discussed. LAY SUMMARY: Infants with an older sibling who is diagnosed with ASD are at increased risk of developing ASD themselves. This article tested whether EEG spectral power in the first year of life can predict whether these infants did or did not develop ASD.

Child and family characteristics moderate agreement between caregiver and clinician report of autism symptoms / E. NEUHAUS in Autism Research, 11-3 (March 2018)  

Public ISBD [article]  inAutism Research > 11-3 (March 2018) . - p.476-487 Titre : Child and family characteristics moderate agreement between caregiver and clinician report of autism symptoms Type de document : Texte imprimé et/ou numérique Auteurs : E. NEUHAUS, Auteur ; Theodore P. BEAUCHAINE, Auteur ; Raphael BERNIER, Auteur ; S. J. WEBB, Auteur Article en page(s) : p.476-487 Langues : Anglais (eng) Mots-clés : autism diagnostic observation schedule  autism spectrum disorder  diagnosis Index. décimale : PER Périodiques Résumé : Rates of autism spectrum disorder (ASD) and age at first diagnosis vary considerably across the United States and are moderated by children's sex, race, ethnicity, and availability of services. We additionally suggest that degree of caregiver-clinician agreement on ASD symptoms may play a role in ASD assessment. Since gold standard ASD assessment integrates caregiver-reported developmental history with clinician observations, differential agreement between reporters across demographic groups may contribute to a host of detrimental outcomes. Here, we investigate whether caregiver-clinician agreement on ASD symptoms varies according to child and family characteristics. Comprehensive data from 2,759 families in the Simons Simplex Collection were analyzed. Linear models were created with caregiver reports predicting clinician reports, and moderating effects of child characteristics and family factors were examined. Poorer reporter correspondence was observed when children had higher IQ scores, stronger adaptive behavior, and more behavioral difficulties. Greater disagreement was also associated with African American racial status (for younger children), lower household income, and paternal social difficulties (for older children). Children's biological sex did not moderate caregiver-clinician agreement. Marked disagreement between caregivers and clinicians could lead to suboptimal or insufficient intervention services and negative experiences for families throughout development. Such families may also be less likely to qualify for research studies, and therefore be underrepresented in the ASD literature. Modified assessment procedures may be required to improve assessment accuracy and family experiences. Autism Res 2018, 11: 476-487. (c) 2017 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: Evaluation of autism spectrum disorder (ASD) incorporates both caregiver and clinician perspectives of symptoms, and disagreement between these perspectives could lead to poorer outcomes for families. Using data from 2,759 families, we show that caregiver-clinician agreement on ASD symptoms is poorer for children with higher cognitive and adaptive skills, more behavioral difficulties, lower household income, and African American racial status. These children may be at higher risk for misdiagnosis, poorer family experiences during evaluations, and poorer representation in ASD research.

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.

Exploring the heterogeneity of neural social indices for genetically distinct etiologies of autism / C. M. HUDAC in Journal of Neurodevelopmental Disorders, 9-1 (December 2017)

EICHLER, Auteur ; Raphael BERNIER, Auteur Article en page(s) : p.24 Langues : Anglais (eng) Mots-clés : Autism spectrum disorders (ASD)  Electroencephalography (EEG)  Likely gene-disrupting mutations  Molecular subtyping  Mu rhythm attenuation  Social cognition  Social perception Index. décimale : PER Périodiques Résumé : BACKGROUND: Autism spectrum disorder (ASD) is a genetically and phenotypically heterogeneous disorder. Promising initiatives utilizing interdisciplinary characterization of ASD suggest phenotypic subtypes related to specific likely gene-disrupting mutations (LGDMs). However, the role of functionally associated LGDMs in the neural social phenotype is unknown. METHODS: In this study of 26 children with ASD (n = 13 with an LGDM) and 13 control children, we characterized patterns of mu attenuation and habituation as children watched videos containing social and nonsocial motions during electroencephalography acquisition. RESULTS: Diagnostic comparisons were consistent with prior work suggesting aberrant mu attenuation in ASD within the upper mu band (10-12 Hz), but typical patterns within the lower mu band (8-10 Hz). Preliminary exploration indicated distinct social sensitization patterns (i.e., increasing mu attenuation for social motion) for children with an LGDM that is primarily expressed during embryonic development. In contrast, children with an LGDM primarily expressed post-embryonic development exhibited stable typical patterns of lower mu attenuation. Neural social indices were associated with social responsiveness, but not cognition. CONCLUSIONS: These findings suggest unique neurophysiological profiles for certain genetic etiologies of ASD, further clarifying possible genetic functional subtypes of ASD and providing insight into mechanisms for targeted treatment approaches.
