Language regression is associated with faster early motor development in children with autism spectrum disorder / Liora MANELIS in Autism Research, 13-1 (January 2020)
[article]
Titre : Language regression is associated with faster early motor development in children with autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Liora MANELIS, Auteur ; Gal MEIRI, Auteur ; Michal ILAN, Auteur ; Hagit FLUSSER, Auteur ; Analya MICHAELOVSKI, Auteur ; Michal FAROY, Auteur ; Orly KERUB, Auteur ; Ilan DINSTEIN, Auteur ; Idan MENASHE, Auteur Article en page(s) : p.145-156 Langues : Anglais (eng) Mots-clés : autism spectrum disorder early development language regression motor development Index. décimale : PER Périodiques Résumé : Language regression (LR) is a consistent and reproducible phenomenon that is reported by ~25% of parents who have children with autism spectrum disorder (ASD). However, there is controversy regarding the etiological and clinical significance of this phenomenon. Here, we examined data from a cohort of 218 children with ASD from the Negev Autism Center in Israel. We identified 36 children with ASD who were reported to exhibit clear LR by their parent on three independent occasions and compared them to 104 children whose parents did not report any concern of regression (NR). We compared a variety of key developmental characteristics across these two groups. We found that the age at which children with ASD in the LR group achieve key developmental milestones of crawling, walking, and use of first words is significantly younger than the age of children in the NR group, and comparable to the age of typically developing children. In contrast, no differences were observed in physical growth characteristics such as head circumference, weight, or height between the groups. Furthermore, almost all children with LR were born close to full term (>35 weeks) and none had a history of hypotonia. Notably, despite their apparently typical early development, children with LR were diagnosed with more severe symptoms of ASD than children with NR. These results strengthen the motivation to continue and study LR among children with ASD and suggest that early detection and intervention studies of ASD may benefit from stratifying children into LR and NR groups. Autism Res 2020, 13: 145-156. (c) 2019 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: The presence of language regression (LR) among children with autism is still a matter of scientific debate. Here, we show that children with autism and reported LR start to crawl, talk, and walk at the same age as other typically developing children and significantly earlier than other children with autism. These findings, along with other medical differences between these groups, suggest that children who experienced LR comprise a distinct subgroup within the autism spectrum.

Nicole TAKAHASHI, Auteur ; Wenchuan QI, Auteur ; Kristina ALDRIDGE, Auteur ; Minqi ZHANG, Auteur ; Shi-Qing XIN, Auteur ; Ying HE, Auteur ; Ye DUAN, Auteur Article en page(s) : p.1302-1317 Langues : Anglais (eng) Mots-clés : Autism Cluster analysis Language regression Facial phenotype Biomarker Outcome indicators Index. décimale : PER Périodiques Résumé : Varied cluster analysis were applied to facial surface measurements from 62 prepubertal boys with essential autism to determine whether facial morphology constitutes viable biomarker for delineation of discrete Autism Spectrum Disorders (ASD) subgroups. Earlier study indicated utility of facial morphology for autism subgrouping (Aldridge et al. in Mol Autism 2(1):15, 2011). Geodesic distances between standardized facial landmarks were measured from three-dimensional stereo-photogrammetric images. Subjects were evaluated for autism-related symptoms, neurologic, cognitive, familial, and phenotypic variants. The most compact cluster is clinically characterized by severe ASD, significant cognitive impairment and language regression. This verifies utility of facially-based ASD subtypes and validates Aldridge et al.’s severe ASD subgroup, notwithstanding different techniques. It suggests that language regression may define a unique ASD subgroup with potential etiologic differences.
