Heterogeneity of autism symptoms in community-referred infants and toddlers at elevated or low familial likelihood of autism / Torrey L. COHENOUR in Autism Research, 16-9 (September 2023)
[article]
Titre : Heterogeneity of autism symptoms in community-referred infants and toddlers at elevated or low familial likelihood of autism Type de document : Texte imprimé et/ou numérique Auteurs : Torrey L. COHENOUR, Auteur ; Amanda GULSRUD, Auteur ; Connie KASARI, Auteur Article en page(s) : p.1739-1749 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Abstract Evidence suggests autistic individuals at elevated familial likelihood of autism spectrum disorder (by virtue of having an autistic sibling) have stronger cognitive abilities on average than autistic individuals with no family history of the condition, who have a low familial likelihood of autism. Investigating phenotypic differences between community-referred infants and toddlers with autism symptoms at elevated or low familial likelihood of autism may provide important insight into heterogeneity in the emerging autism phenotype. This study compared behavioral, cognitive, and language abilities of community-referred infants and toddlers with confirmed autism symptoms at elevated (EL) or low familial likelihood of autism (LL). Participants were 121 children aged 12 to 36?months who participated in two larger randomized trials of parent-mediated interventions for children with autism symptoms. Behavioral phenotypes were compared across three groups: children with at least one autistic sibling (EL-Sibs, n=30), those with at least one older, non-autistic sibling and no family history of autism (LL-Sibs, n=40), and first-born children with no family history of autism (LL-FB, n=51). EL-Sibs had less severe autism symptoms and stronger cognitive abilities than children in LL groups. While the rate of receptive language delay was similar across groups, the rate of expressive language delay was markedly lower among EL-Sibs. After controlling for age and nonverbal cognitive ability, EL-Sibs were significantly less likely to present with expressive language delay than LL-Sibs. Familial likelihood of autism may play an important role in shaping the emerging autism phenotype in infancy and toddlerhood.
