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, 21-2 (February 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) 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.

[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.

Autistic children (5?13 years) with sleep problems were randomised to the Sleeping Sound intervention or Treatment as Usual (TAU). At 12-month follow-up (n?=?150), caregivers of children in the Sleeping Sound group reported greater reduction in child sleep problems compared to TAU (p?.001, effect size: ? 0.4). The long-term benefits of the intervention were greater for children taking sleep medication, children of parents who were not experiencing psychological distress, and children with greater autism severity. The Sleeping Sound intervention demonstrated sustained improvements in child sleep. Identified moderators may inform treatment by indicating which subgroups may benefit from further support.

Outcome measures of interest include social and communication skill development in children, quality of life and stress for parents. Eligible (diagnosed ASD, preschool age) participants were randomised into 2 groups HB (n = 28) and CB (n = 28). A WL (n = 29) comparison group was also recruited. HB and CB groups had 12-month programs. Pre and post assessments were conducted using formal and informal measures. Children in the CB group improved significantly more than HB and WL groups on some social and communication measures. On parent measures outcomes varied with CB group parents making the most gains in perception of competence and quality of life. The small group centre-based program combined with parent program resulted in the best most cost effective outcomes for children and families however this is not an option for all. The CB program did not suit some children and families. The heterogeneity of the autism population indicates that a range of intervention options is necessary to meet the needs of children with autism and their families.
