Is inhibitory control a 'no-go' in adolescents with autism spectrum disorder? / Anji VARA in Molecular Autism, (January 2014)  

Public ISBD [article]  inMolecular Autism > (January 2014) Titre : Is inhibitory control a 'no-go' in adolescents with autism spectrum disorder? Type de document : Texte imprimé et/ou numérique Auteurs : Anji VARA, Auteur ; Elizabeth W. PANG, Auteur ; Krissy DOYLE-THOMAS, Auteur ; Julie VIDAL, Auteur ; Margot J. TAYLOR, Auteur ; Evdokia ANAGNOSTOU, Auteur Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Autism spectrum disorder (ASD) refers to a range of neurodevelopmental conditions characterized by social communication deficits, repetitive behaviours, and restrictive interests. Impaired inhibition has been suggested to exacerbate the core symptoms of ASD. This is particularly critical during adolescence when social skills are maturing to adult levels. Using magnetoencephalography (MEG), we identified the location and timing pattern of neural activity associated with inhibition in adolescents with autism, compared to typically developing adolescents. The MEG data from 15 adolescents with ASD and 15 age-matched controls (13 to 17 years) were collected during a go/no-go task with inverse ratios of go/no-go trials in two conditions: an inhibition condition (1:2) and a baseline condition (2:1). No-go trials from the two conditions were analyzed using beamformer source localizations from 200ms to 400ms post-stimulus onset. Significant activations were determined using permutation testing. Adolescents with ASD recruited first the right middle frontal gyrus (200 to 250ms) followed by the left postcentral gyrus (250 to 300ms) and finally the left middle frontal and right medial frontal gyri (300 to 400ms). Typically developing adolescents recruited first the left middle frontal gyrus (200 to 250ms), followed by the left superior and inferior frontal gyri (250 to 300ms), then the right middle temporal gyrus (300 to 350ms), and finally the superior and precentral gyri and right inferior lobule (300 to 400ms). Adolescents with ASD showed recruitment limited largely to the frontal cortex unlike typically developing adolescents who recruited parietal and temporal regions as well. These findings support the presence of an atypical, restricted inhibitory network in adolescents with ASD compared to controls.

White matter and development in children with an autism spectrum disorder / Kathleen M. MAK-FAN in Autism, 17-5 (September 2013)  

Public ISBD [article]  inAutism > 17-5 (September 2013) . - p.541-557 Titre : White matter and development in children with an autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Kathleen M. MAK-FAN, Auteur ; Drew MORRIS, Auteur ; Julie VIDAL, Auteur ; Evdokia ANAGNOSTOU, Auteur ; Wendy ROBERTS, Auteur ; Margot J. TAYLOR, Auteur Article en page(s) : p.541-557 Langues : Anglais (eng) Mots-clés : autism spectrum disorder  brain structure  development  white matter  diffusion tensor imaging  diffusivity Index. décimale : PER Périodiques Résumé : Recent research suggests that brain development follows an abnormal trajectory in children with autism spectrum disorders (ASD). The current study examined changes in diffusivity with age within defined white matter tracts in a group of typically developing children and a group of children with an ASD, aged 6 to 14 years. Age by group interactions were observed for frontal, long distant, interhemispheric and posterior tracts, for longitudinal, radial and mean diffusivity, but not for fractional anisotropy. In all cases, these measures of diffusivity decreased with age in the typically developing group, but showed little or no change in the ASD group. This supports the hypothesis of an abnormal developmental trajectory of white matter in this population, which could have profound effects on the development of neural connectivity and contribute to atypical cognitive development in children with ASD.
