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)
[article]
Titre : Autism Spectrum Disorder Symptoms in Infants with Fragile X Syndrome: A Prospective Case Series Type de document : Texte imprimé et/ou numérique Auteurs : Abigail L. HOGAN, Auteur ; Kelly E. CARAVELLA, Auteur ; Jordan EZELL, Auteur ; Lisa RAGUE, Auteur ; Kimberly HILLS, Auteur ; Jane E. ROBERTS, Auteur Article en page(s) : p.1628-1644 Langues : Anglais (eng) Mots-clés : Fragile X syndrome Autism spectrum disorder Infants Case studies Index. décimale : PER Périodiques Résumé : No studies to date have prospectively examined early autism spectrum disorder (ASD) markers in infants with fragile X syndrome (FXS), who are at elevated risk for ASD. 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.

Titre : Neural correlates of face processing among preschoolers with fragile X syndrome, autism spectrum disorder, autism siblings, and typical development Type de document : Texte imprimé et/ou numérique Auteurs : Maggie W. GUY, Auteur ; Abigail L. HOGAN, Auteur ; Jane E. ROBERTS, Auteur Article en page(s) : p.89-108 Index. décimale : PER Périodiques Résumé : Abstract The current study examined patterns of event-related potential (ERP) responses during a face processing task in groups of preschoolers uniquely impacted by autism spectrum disorder (ASD), including (1) children with ASD; (2) children with fragile X syndrome (FXS); (3) children with familial risk for ASD, but without a diagnosis (i.e., ASIBs); and (4) a low-risk control (LRC) group. Children with FXS have a high incidence of ASD diagnoses, but there have been no studies of the ERP response to faces in children with FXS and little work focused on children with ASD who have cognitive impairment. The current study examined children's ERP responses to faces and houses in four groups: LRC (N?=?28, age?=?5.2?years), ASIB (N?=?23, age?=?5.5?years), FXS (N?=?19, age?= 5.82?years), and ASD (N?=?23, age?=?5.5?years). The FXS and ASD groups were characterized by the presence of cognitive impairment. Pictures of upright and inverted faces and houses were presented while recording EEG with a 128-channel system. The N170 occurred at about 200?ms post stimulus onset, was largest on the posterior-lateral electrodes, and was larger for faces than houses. The P1 and N170 ERP components were larger for the FXS group than for the other three groups. The N170 ERP amplitude for the ASD and ASIB groups was smaller than both the LRC and FXS groups, and the LRC and FXS groups had the largest N170 responses on the right side. No difference was found in N170 latency between groups. The similarity of the ASD and ASIB responses suggest a common genetic or environmental origin of the reduced response. Although children with FXS have a high incidence of ASD outcomes, they differed from ASD and ASIB children in this study. Specifically, the children with FXS were hyperresponsive to all stimulus types while the ASD and ASIB groups showed attenuated responses for specific stimuli.
