Adaptive skill trajectories in infants with fragile X syndrome contrasted to typical controls and infants at high risk for autism / Kelly E. CARAVELLA in Research in Autism Spectrum Disorders, 40 (August 2017)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 40 (August 2017) . - p.1-12 Titre : Adaptive skill trajectories in infants with fragile X syndrome contrasted to typical controls and infants at high risk for autism Type de document : Texte imprimé et/ou numérique Auteurs : Kelly E. CARAVELLA, Auteur ; Jane E. ROBERTS, Auteur Article en page(s) : p.1-12 Langues : Anglais (eng) Mots-clés : Adaptive behavior  Fragile X syndrome  Infancy  Autism infant siblings Index. décimale : PER Périodiques Résumé : AbstractBackground Adaptive behaviors are essential for optimal outcomes and independence in individuals with developmental disabilities. This study examined longitudinal trajectories of adaptive behavior in infants with fragile X syndrome (FXS), compared to typical development (TD) and infant siblings of children diagnosed with autism (ASIBs). Method Participants included 76 male infants (FXS = 25, ASIBs = 27, TD = 24) assessed up to 4 times between 6 and 24 months of age for a total of 215 assessments of adaptive behavior. A sample of 12 females with FXS was included for a comparative sex analysis. Results Results indicate that infant males with FXS displayed lower initial adaptive behavior across all domains that emerged by 9 months-of-age with slower growth rates than both comparison groups. A flat profile across the domains at 24 months was evident. Increased severity of autism symptoms was related to reduced adaptive skills at 24 months-of-age. Females with FXS displayed higher scores than males on the Socialization and Motor domains and equivalent scores on the Communication and Daily Living domains at 9 months-of-age with different rates of growth across domains. Conclusions This is the first study to provide evidence of etiological specificity in adaptive behavior profiles during infancy across two populations at high risk for ASD. These findings support targeted adaptive behavior interventions in young children with FXS beginning as early at 9 months of age to reduce identified deficits and the cascading impacts of these early impairments.

Arousal Modulation in Females with Fragile X or Turner Syndrome / Jane E. ROBERTS in Journal of Autism and Developmental Disorders, 38-1 (January 2008)

Relative to the comparison group, for whom a greater increase in skin conductance was associated with poor arithmetic performance and less risk taking behavior, females with fragile X displayed a minimal increase in heart activity that was nevertheless associated with poor performance on mental arithmetic. In contrast, no arousal–cognitive performance relationship emerged for the group with Turner syndrome. Taken together, our findings suggest that distinct profiles of arousal modulation might be associated with cognitive deficits in these syndrome populations.

Autism Spectrum Disorder Symptoms in Infants with Fragile X Syndrome: A Prospective Case Series / Abigail L. HOGAN in Journal of Autism and Developmental Disorders, 47-6 (June 2017)

This paper describes the developmental profiles of eight infants with FXS from 9 to 24 months of age. Four meet diagnostic criteria for ASD at 24 months of age, and four do not. Trends in these case studies suggest that early social-communicative deficits differentiate infants with and without later ASD diagnoses in ways that are similar to later-born siblings of children with ASD. Repetitive behaviors and cognitive and adaptive impairments are present in all FXS infants throughout development, suggesting that these deficits reflect the general FXS phenotype and not ASD in FXS specifically.

Behavioral and Physiological Responses to Child-Directed Speech of Children with Autism Spectrum Disorders or Typical Development / Linda R. WATSON in Journal of Autism and Developmental Disorders, 42-8 (August 2012)

Behavioral (looking) and physiological (heart rate and respiratory sinus arrhythmia) measures were collected. Boys with autism looked equally as much as chronological age-matched peers at nonsocial stimuli, but less at CDS stimuli. Boys with autism and language age-matched peers differed in patterns of looking at live versus videotaped CDS stimuli. Boys with autism demonstrated faster heart rates than chronological age-matched peers, but did not differ significantly on respiratory sinus arrhythmia. Reduced attention during CDS may restrict language-learning opportunities for children with autism. The heart rate findings suggest that young children with autism have a nonspecific elevated arousal level.

Brief Report: Autism Symptoms in Infants with Fragile X Syndrome / Jane E. ROBERTS in Journal of Autism and Developmental Disorders, 46-12 (December 2016)

Although 50–75?% of children with FXS meet ASD criteria, no studies have compared ASD symptoms in infants with FXS versus other high risk groups, such as siblings of children with ASD (ASIBs). Using the Autism Observation Scale for Infants, our findings indicate that 53?% of 12-month infants with FXS fall in the “at risk” category compared to 17 and 6?% for age-matched ASIBs and controls, respectively. Elevated atypical motor behaviors were associated with elevated risk for FXS. Cross-syndrome comparisons are essential to understanding the heterogeneity of ASD and identifying candidate markers that will facilitate differential diagnosis of ASD in genetic disorders such as FXS.
