Titre : Alpha Asymmetry in Infants at Risk for Autism Spectrum Disorders Type de document : Texte imprimé et/ou numérique Auteurs : Laurel GABARD-DURNAM, Auteur ; Adrienne L. TIERNEY, Auteur ; Vanessa VOGEL-FARLEY, Auteur ; Helen TAGER-FLUSBERG, Auteur ; Charles A. NELSON, Auteur Article en page(s) : p.473-480 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder Infant siblings Electroencephalography Frontal alpha asymmetry Endophenotype Index. décimale : PER Périodiques Résumé : An emerging focus of research on autism spectrum disorder (ASD) targets the identification of early-developing ASD endophenotypes using infant siblings of affected children. One potential neural endophenotype is resting frontal electroencephalogram (EEG) alpha asymmetry, a metric of hemispheric organization. Here, we examined the development of frontal EEG alpha asymmetry in ASD high-risk and low-risk infant populations. Our findings demonstrate that low and high-risk infants show different patterns of alpha asymmetry at 6 months of age and opposite growth trajectories in asymmetry over the following 12 months. These results support the candidacy of alpha asymmetry as an early neural ASD endophenotype.

Recent work suggests performance on these paradigms may associate with clinical features of ASD. We evaluate metrics from a visual exploration paradigm in 4-to-11-year-old children with ASD (n?=?23; 18 males) and typical development (TD; n?=?23; 13 males). Presented with arrays containing faces and nonsocial stimuli, children with ASD looked less at (p?=?0.002) and showed fewer fixations to (p?=?0.022) faces than TD children, and spent less time looking at each object on average (p?=?0.004). Attention to the screen and faces correlated positively with social and cognitive skills in the ASD group (ps?.05). This work furthers our understanding of objective measures of visual exploration in ASD and its potential for quantifying features of ASD.

NELSON, Auteur Article en page(s) : p.187-198 Langues : Anglais (eng) Mots-clés : autism EEG coherence face processing hemispheric specialization endophenotype gamma infancy Index. décimale : PER Périodiques Résumé : Among the many experimental findings that tend to distinguish those with and without autism spectrum disorder (ASD) are face processing deficits, reduced hemispheric specialization, and atypical neurostructural and functional connectivity. To investigate the earliest manifestations of these features, we examined lateralization of event-related gamma-band coherence to faces during the first year of life in infants at high risk for autism (HRA; defined as having an older sibling with ASD) who were compared with low-risk comparison (LRC) infants, defined as having no family history of ASD. Participants included 49 HRA and 46 LRC infants who contributed a total of 127 data sets at 6 and 12 months. Electroencephalography was recorded while infants viewed images of familiar/unfamiliar faces. Event-related gamma-band (30–50?Hz) phase coherence between anterior–posterior electrode pairs for left and right hemispheres was computed. Developmental trajectories for lateralization of intra-hemispheric coherence were significantly different in HRA and LRC infants: by 12 months, HRA infants showed significantly greater leftward lateralization compared with LRC infants who showed rightward lateralization. Preliminary results indicate that infants who later met criteria for ASD were those that showed the greatest leftward lateralization. HRA infants demonstrate an aberrant pattern of leftward lateralization of intra-hemispheric coherence by the end of the first year of life, suggesting that the network specialized for face processing may develop atypically. Further, infants with the greatest leftward asymmetry at 12 months where those that later met criteria for ASD, providing support to the growing body of evidence that atypical hemispheric specialization may be an early neurobiological marker for ASD.

Titre : Commentary: Developmental origins of autism and ADHD – a commentary on Johnson et al. () Type de document : Texte imprimé et/ou numérique Auteurs : Charles A. NELSON, Auteur Article en page(s) : p.248-250 Langues : Anglais (eng) Mots-clés : Autism ADHD neurodevelopmental origins early experience neural and molecular mechanisms Index. décimale : PER Périodiques Résumé : Autism (autistic spectrum disorder, ASD) and attention deficit hyperactivity disorder (ADHD) are two highly prevalent neurodevelopmental disorders. Current estimates for autism exceed 1% For ADHD, the 2013 US-based life time prevalence figure is 11%. Both disorders are also highly heritable. Intriguingly, approximately 50% of children with ASD also meet criteria for ADHD. Between their high heritability and comorbidity, some have wondered whether these two seemingly different disorders might in fact be related at some deep neurobiological level. The notion that these two disorders may be related is surprising when one considers the fact that autism generally appears in the first 1–2 years of life, whereas it is virtually impossible to identify ADHD during this time frame; indeed, inattentiveness and hyperactivity tend to be traits that are shared by nearly all toddlers, making a stable diagnosis of ADHD virtually impossible until early childhood (although a reliable diagnosis can generally be made during the preschool period). Like many neurodevelopmental disorders, early identification and early treatment are essential to easing the life time burden of these disorders. Of course, early treatment is predicated on early identification and it is for this reason that the review article by Johnson and colleagues is so intriguing, as it sets out to determine whether these disorders can be identified in the infancy period. It also raises a number of puzzling issues that remain undiscussed.
