Parent-reported patterns of loss and gain in communication in 1- to 2-year-old children are not unique to autism spectrum disorder / Amanda BRIGNELL in Autism, 21-3 (April 2017)
[article]
Titre : Parent-reported patterns of loss and gain in communication in 1- to 2-year-old children are not unique to autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Amanda BRIGNELL, Auteur ; Katrina WILLIAMS, Auteur ; Margot PRIOR, Auteur ; Susan DONATH, Auteur ; Sheena REILLY, Auteur ; Edith L. BAVIN, Auteur ; Patricia EADIE, Auteur ; Angela T. MORGAN, Auteur Article en page(s) : p.344-356 Langues : Anglais (eng) Mots-clés : Autism Spectrum Disorder/ psychology Child, Preschool Female Humans Infant Language Development Male Parents/ psychology Vocabulary autism spectrum disorder communication language regression skill loss trajectory Index. décimale : PER Périodiques Résumé : We compared loss and gain in communication from 1 to 2?years in children later diagnosed with autism spectrum disorder (n=41), language impairment (n=110) and in children with typical language development at 7?years (n=831). Participants were selected from a prospective population cohort study of child language (the Early Language in Victoria Study). Parent-completed communication tools were used. As a group, children with autism spectrum disorder demonstrated slower median skill gain, with an increasing gap between trajectories compared to children with typical development and language impairment. A proportion from all groups lost skills in at least one domain (autism spectrum disorder (41%), language impairment (30%), typical development (26%)), with more children with autism spectrum disorder losing skills in more than one domain (autism spectrum disorder (47%), language impairment (15%, p=0.0003), typical development (16%, p?0.001)). Loss was most common for all groups in the domain of 'emotion and eye gaze' but with a higher proportion for children with autism spectrum disorder (27%; language impairment (12%, p=0.03), typical development (14%, p=0.03)). A higher proportion of children with autism spectrum disorder also lost skills in gesture (p=0.01), sounds (p=0.009) and understanding (p=0.004) compared to children with typical development but not with language impairment. These findings add to our understanding of early communication development and highlight that loss is not unique to autism spectrum disorder.

Titre : Developmental regression among children with autism spectrum disorder: Onset, duration, and effects on functional outcomes Type de document : Texte imprimé et/ou numérique Auteurs : Robin P. GOIN-KOCHEL, Auteur ; Amy ESLER, Auteur ; Stephen M. KANNE, Auteur ; Vanessa HUS, Auteur Article en page(s) : p.890-898 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder Regression Skill loss Cognition Adaptive functioning Outcomes Index. décimale : PER Périodiques Résumé : Abstract Studies using varied methods report that developmental regression occurs in a sizeable proportion of children with autism spectrum disorder (ASD). Findings are equivocal as to whether regression is associated with poorer cognitive and adaptive functioning. This study examined retrospective parent report in 2105 Simons Simplex Collection participants with ASD. Children were classified as having “full” or “subthreshold” losses on language and/or other skills using items from the Autism Diagnostic Interview-Revised (ADI-R) and a supplemental interview to capture more subtle regressions. Overall, 36.9% of children had some type of regression (27.8% language, 27.0% other-skill loss), with the supplemental interview capturing 11.7% of losses that would have been missed using the ADI-R alone. This figure is consistent with previous parent-report studies but lower than clinician-observed rates in prospective investigations. Early language losses—either full or subthreshold—and full other-skill losses appear to be associated with more deleterious outcomes by middle childhood. Findings may signify the need for more immediate and/or intense therapies for children who have even minor skill losses, particularly in language skills. Results further demonstrate the utility of an expanded set of additional queries with slightly modified criteria to capture such early, subtle losses.

[article]
Titre : Prevalence and Age of Onset of Regression in Children with Autism Spectrum Disorder: A Systematic Review and Meta-analytical Update Type de document : Texte imprimé et/ou numérique Auteurs : Christine TAN, Auteur ; Veronica FREWER, Auteur ; Georgina COX, Auteur ; Katrina WILLIAMS, Auteur ; Alexandra URE, Auteur Article en page(s) : p.582-598 Langues : Anglais (eng) Mots-clés : autism children onset prevalence regression skill loss Index. décimale : PER Périodiques Résumé : A systematic review published in 2013 reported 32% of children on the autism spectrum experience skill loss, known as autistic regression. However, the frequency varied depending on definition and measures used to capture skills. Retrospective parent report and prospective observation indicate loss of language and/or social skills, with motor skills typically unaffected. Our aim was to update the prevalence and age of onset of autistic regression through a meta-analysis of the literature to understand if there have been changes to the reported onset and prevalence since 2010. A systematic literature search was conducted using Medline, Embase, PsycINFO, and the Cochrane Library databases and included studies published from 2010 onward. Risk of bias assessment was performed on included studies. A random effects model was used to calculate the pooled prevalence and age of onset of autistic regression. Ninety-seven studies were included in the systematic review, of which 75 studies involving 33,014 participants had sufficient data for meta-analytic syntheses. The pooled proportion of autistic regression was 30% (95% confidence interval [CI]: 27-32%) but heterogeneity was high (I(2) =?96.91) and did not reduce with sensitivity or subgroup analyses based on study design or clinical differences, respectively. Prevalence varied according to risk of bias (low: 27%) and definition of regression (language: 20%, language/social: 40%, mixed: 30%, and unspecified: 27%). Weighted average age of onset was 19.8?months. Findings from this meta-analysis highlight the importance of developing a standardized definition of autistic regression, and tools to measure this at multiple time points during early childhood development. LAY SUMMARY: About a third of children with Autism Spectrum Disorder experience loss of skills, which is also known as autistic regression. This paper provides an update of the rate of autistic regression in children and the age when they first experience loss of skills, based on current studies. The findings from this review contribute to our understanding of the onset patterns of autistic regression. Unfortunately, studies are not sufficiently similar, making it difficult to provide clear answers on the exact timing or type of regression seen in different children.
