Mid-childhood outcomes of infant siblings at familial high-risk of autism spectrum disorder / Elizabeth SHEPHARD in Autism Research, 10-3 (March 2017)
[article]
Titre : Mid-childhood outcomes of infant siblings at familial high-risk of autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Elizabeth SHEPHARD, Auteur ; Bosiljka MILOSAVLJEVIC, Auteur ; Greg PASCO, Auteur ; Emily J. H. JONES, Auteur ; Teodora GLIGA, Auteur ; Francesca HAPPE, Auteur ; Mark H. JOHNSON, Auteur ; Tony CHARMAN, Auteur ; THE BASIS TEAM,, Auteur Article en page(s) : p.546-557 Langues : Anglais (eng) Mots-clés : high-risk siblings clinical outcomes ADHD anxiety broader autism phenotype Index. décimale : PER Périodiques Résumé : Almost 20% of infants with an older sibling with autism spectrum disorder (ASD) exhibit ASD themselves by age 3 years. The longer-term outcomes of high-risk infants are less clear. We examined symptoms of ASD, attention-deficit/hyperactivity disorder (ADHD) and anxiety, language, IQ, and adaptive behaviour at age 7 years in high- and low-risk children prospectively studied since the first year of life. Clinical outcomes were compared between high-risk children who met diagnostic criteria for ASD at age 7 (HR-ASD-7 group, n = 15), high-risk children without ASD (HR-Non-ASD-7 group, n = 24), and low-risk control children (LR group, n = 37). Diagnostic stability between age 3 and 7 years was moderate, with five children who did not meet diagnostic criteria for ASD at age 3 years being assigned the diagnosis at age 7, and three children showing the opposite pattern. The HR-ASD-7 group showed elevated ADHD and anxiety symptoms and had lower adaptive behaviour scores than LR controls. The HR-Non-ASD-7 group had higher repetitive behaviour, lower adaptive functioning and elevated scores on one anxiety subscale (Separation Anxiety) compared to LR controls, but evidence for subclinical ASD symptoms (the broader autism phenotype, BAP) was limited in the group as a whole, although we identified a subgroup with elevated ASD traits. The difficulties experienced by high-risk siblings at school-age extend beyond ASD symptoms. The pattern of difficulties exhibited by the HR-ASD-7 group may inform our understanding of developmental trajectories of co-occurring psychopathology in ASD.

We report outcomes at age 3 years using the Mullen Scales of Early Learning, the Autism Diagnostic Observation Schedule (ADOS), the Autism Diagnostic Interview—Revised (ADI-R) and adaptive functioning on the Vineland Adaptive Behavior Scales. Around 11% of high-risk siblings had mild-to-moderate levels of developmental delay, a rate higher than the low-risk controls. The groups did not differ in the proportion of toddlers with mild-to-moderate language delay. Thirty percent of high-risk siblings had elevated scores on the ADOS, double the rate seen in the low-risk controls. High-risk siblings also had higher parent reported levels of ASD symptoms on the ADI-R and lower adaptive functioning on the Vineland. Males were more likely to show higher levels of ASD symptoms and lower levels of developmental ability and adaptive behavior than females across most measures but not mild-to-moderate language delay. Lower maternal education was associated with lower developmental and adaptive behavior outcomes. These findings are evidence for early emerging characteristics related to the “broader autism phenotype” (BAP) previously described in older family members of individuals with ASD. There is a need for ongoing clinical monitoring of high-risk siblings who do not have an ASD by age 3 years, as well as continued follow-up into school age to determine their developmental and behavioral outcomes.

Titre : Parent-delivered early intervention in infants at risk for ASD: Effects on electrophysiological and habituation measures of social attention Type de document : Texte imprimé et/ou numérique Auteurs : Emily J. H. JONES, Auteur ; Geraldine DAWSON, Auteur ; Jean KELLY, Auteur ; Annette ESTES, Auteur ; Sara JANE WEBB, Auteur Article en page(s) : p.961-972 Langues : Anglais (eng) Mots-clés : autism ASD infant high-risk neurocognitive social attention promoting first relationships Index. décimale : PER Périodiques Résumé : Prospective longitudinal studies of infants with older siblings with autism spectrum disorder (ASD) have indicated that differences in the neurocognitive systems underlying social attention may emerge prior to the child meeting ASD diagnostic criteria. Thus, targeting social attention with early intervention might have the potential to alter developmental trajectories for infants at high risk for ASD. Electrophysiological and habituation measures of social attention were collected at 6, 12, and 18 months in a group of high-risk infant siblings of children with ASD (N?=?33). Between 9 and 11 months of age, infant siblings received a parent-delivered intervention, promoting first relationships (PFR), (n?=?19) or on-going assessment without intervention (n?=?14). PFR has been previously shown to increase parental responsivity to infant social communicative cues and infant contingent responding. Compared to infants who only received assessment and monitoring, infants who received the intervention showed improvements in neurocognitive metrics of social attention, as reflected in a greater reduction in habituation times to face versus object stimuli between 6 and 12 months, maintained at 18 months; a greater increase in frontal EEG theta power between 6 and 12 months; and a more comparable P400 response to faces and objects at 12 months. The high-risk infants who received the intervention showed a pattern of responses that appeared closer to the normative responses of two groups of age-matched low-risk control participants. Though replication is necessary, these results suggest that early parent-mediated intervention has the potential to impact the brain systems underpinning social attention in infants at familial risk for ASD.

Index. décimale : PER Périodiques Résumé : Restricted interests and repetitive behaviours are central to the diagnosis of autism and can have profound effects on daily activities and quality of life. These challenges are also linked to other co-occurring conditions such as anxiety and sensory sensitivities. Here, we looked at whether early emerging signs of anxiety and sensory problems appear before symptoms of autism by studying infants with a family history of autism, as these infants are more likely to develop autism themselves. Studying infant siblings provides an opportunity for researchers to focus on early developmental markers of autism as these infants can be followed from birth. This study found that early infant signs of anxiety (e.g. fear/shyness) predicted later perceptual sensitivity, and those infants who scored higher on fear/shyness and sensitivity were more likely to experience more persistent repetitive behaviours, but also social and communication difficulties in toddlerhood. Early signs of anxiety and perceptual sensitivity may thus relate to both later social difficulties and repetitive behaviours. These findings support the importance of further research exploring the causal links between these domains in relation to autism, resulting in increased understanding of children who go onto develop autism in the future and guiding early interventions and supports.

Resting state EEG provides a window into spontaneous local and long-range neuronal synchronization and has been investigated in many ASD studies, but results are inconsistent. Unbiased investigation in large and comprehensive samples focusing on replicability is needed. METHODS: We quantified resting state EEG alpha peak metrics, power spectrum (PS, 2-32 Hz) and functional connectivity (FC) in 411 children, adolescents and adults (n=212 ASD, n=199 neurotypicals [NT], all with IQ?>?75). We performed analyses in source-space using individual head models derived from the participants' MRIs. We tested for differences in mean and variance between the ASD and NT groups for both PS and FC using linear mixed effects models accounting for age, sex, IQ and site effects. Then, we used machine learning to assess whether a multivariate combination of EEG features could better separate ASD and NT participants. All analyses were embedded within a train-validation approach (70%-30% split). RESULTS: In the training dataset, we found an interaction between age and group for the reactivity to eye opening (p=.042 uncorrected), and a significant but weak multivariate ASD vs. NT classification performance for PS and FC (sensitivity 0.52-0.62, specificity 0.59-0.73). None of these findings replicated significantly in the validation dataset, although the effect size in the validation dataset overlapped with the prediction interval from the training dataset. LIMITATIONS: The statistical power to detect weak effects-of the magnitude of those found in the training dataset-in the validation dataset is small, and we cannot fully conclude on the reproducibility of the training dataset's effects. CONCLUSIONS: This suggests that PS and FC values in ASD and NT have a strong overlap, and that differences between both groups (in both mean and variance) have, at best, a small effect size. Larger studies would be needed to investigate and replicate such potential effects.
