Titre : A Case Study of Childhood Disintegrative Disorder Using Systematic Analysis of Family Home Movies Type de document : Texte imprimé et/ou numérique Auteurs : Ruben PALOMO, Auteur ; Sally OZONOFF, Auteur ; Gregory S. YOUNG, Auteur ; Costanza COLOMBI, Auteur ; Ian COOK, Auteur ; Stacy GOLDRING, Auteur ; Meagan THOMPSON, Auteur Année de publication : 2008 Article en page(s) : p.1853-1858 Langues : Anglais (eng) Mots-clés : Childhood-disintegrative-disorder Autism Regression Index. décimale : PER Périodiques Résumé : Childhood disintegrative disorder (CDD) is a rare pervasive developmental disorder that involves regression after a period of at least 2 years of typical development. This case study presents data from family home movies, coded by reliable raters using an objective coding system, to examine the trajectory of development in one child with a reported regression at 48 months of age. Coding substantiated parent reports of mostly typical early development, followed by later catastrophic loss of skills across many developmental domains. Differential diagnosis of CDD and autism with regression is discussed.

Titre : Deferred and immediate imitation in regressive and early onset autism Type de document : Texte imprimé et/ou numérique Auteurs : Sally J ROGERS, Auteur ; Sally OZONOFF, Auteur ; Gregory S. YOUNG, Auteur ; Ian COOK, Auteur ; Angelo GIOLZETTI, Auteur Année de publication : 2008 Article en page(s) : p.449–457 Langues : Anglais (eng) Mots-clés : Autistic-disorder development developmental-delay mental-retardation pervasive-developmental-disorder preschool-children imitation Index. décimale : PER Périodiques Résumé : Deferred imitation has long held a privileged position in early cognitive development, considered an early marker of representational thought with links to language development and symbolic processes. Children with autism have difficulties with several abilities generally thought to be related to deferred imitation: immediate imitation, language, and symbolic play. However, few studies have examined deferred imitation in early autism. The present study examined both deferred, spontaneous imitation and immediate, elicited imitation on a set of carefully matched tasks in 36 young children with autism: 16 with early onset autism, 20 with regressive autism and two contrast groups, younger typically developing children (n = 20) and age matched children with significant developmental delays (n = 21). Analyses of co-variance controlling for differences in verbal mental age revealed significant main effects for task, but no main effect of group and no interaction of task by group. Deferred imitation scores were lower than immediate imitation scores for all groups. Imitation performance was related to overall intellectual functioning for all groups, and there were moderate and significant relations between imitation in the immediate elicited condition and in the spontaneous deferred condition for all groups. Finally, there were no differences between onset subgroups in imitation scores, suggesting that the two share a similar phenotype involving both types of imitation.

WILSON, Auteur ; Jurriaan M. PETERS, Auteur ; Monisha N. GOYAL, Auteur ; E. Martina BEBIN, Auteur ; Hope NORTHRUP, Auteur ; Darcy KRUEGER, Auteur ; Andrew F. LEUCHTER, Auteur ; Mustafa SAHIN, Auteur Article en page(s) : p.916-923 Langues : Anglais (eng) Mots-clés : Autism Biomarkers Eeg Tsc Index. décimale : PER Périodiques Résumé : Tuberous sclerosis complex (TSC) is a multisystem disorder with increased prevalence of autism spectrum disorders (ASDs). This project aimed to characterize the autism phenotype of TSC and identify biomarkers of risk for ASD. Because abnormalities of EEG during sleep are tied to neurodevelopment in children, we compared electroencephalographic (EEG) measures during Stage II sleep in TSC children who either did (ASD+) or did not (ASD-) exhibit symptoms of ASD over 36-month follow up. Relative alpha band power was significantly elevated in the ASD+ group at 24 months of age with smaller differences at younger ages, suggesting this may arise from differences in brain development. These findings suggest that EEG features could enhance the detection of risk for ASD.

Titre : Imitating actions on objects in early-onset and regressive autism: Effects and implications of task characteristics on performance Type de document : Texte imprimé et/ou numérique Auteurs : Sally J ROGERS, Auteur ; Sally OZONOFF, Auteur ; Gregory S. YOUNG, Auteur ; Ian COOK, Auteur ; Angelo GIOLZETTI, Auteur Année de publication : 2010 Article en page(s) : p.71-85 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : This study was designed to examine the nature of object imitation performance in early autism. We hypothesized that imitation would be relatively preserved when behaviors on objects resulted in salient instrumental effects. We designed tasks in which, in one condition, the motor action resulted in a salient, meaningful effect on an object, whereas in the other condition, the same action resulted in a less salient effect because of differing object characteristics. The motor aspects of the tasks did not vary across conditions. Four participant groups of 2- to 5-year-olds were examined: 17 children with early-onset autism, 24 children with regressive onset autism, 22 children with developmental delays, and 22 children with typical development. Groups were matched on nonverbal skills, and differences in verbal development were examined as a moderator of imitative ability. Results revealed an interaction of group by condition, with the combined autism group failing more tasks than the combined comparison groups, and failing more tasks in the less salient condition than in the more salient condition, as hypothesized. Analyses of autism subgroups revealed these effects were primarily because of the regression onset group. Accuracy of motor performance was examined by analyzing errors. Among children passing imitative acts, there were no group differences and no condition effects in the number, type, or pattern of performance errors. Among children passing the tasks, the group with autism did not demonstrate more emulation errors (imitating the goal but not the means) than other groups. There was no evidence that either motor or attentional aspects of the tasks contributed to the poorer imitative performance of the children with autism.
