In Ontario, Canada, developmental data are regularly collected for all kindergarten children with the Early Development Instrument (EDI), a teacher-completed questionnaire that provides information on children's status in five domains: physical, social, emotional, language/cognitive, and communication/general knowledge. Our main research questions are: (a) are there differences in kindergarten EDI domain scores between children who are diagnosed with ASD by Grade 3 and those who develop typically or have other disabilities?; (b) do these differences show a different pattern in relation to an early (by kindergarten) or late (by Grade 3) diagnosis?; and (c) are there specific subdomains on the EDI that demonstrate a consistent pattern of differences? EDI domain and subdomain scores were compared among groups using multivariate analysis of variance controlling for age, gender, EDI year, and EDI year by age interaction. Children with ASD, regardless of timing of identification, had significantly lower scores on all domains of the EDI than typically developing children. Children with later ASD diagnosis had higher scores in kindergarten in cognitive areas but lower scores in social-emotional areas than children with other disabilities. These findings support the potential of the EDI to monitor ASD-like behaviors at the population level. Autism Res 2018, 11: 410-420.

LAY SUMMARY: Identifying behavior patterns among kindergarten children that may be specific to autism spectrum disorder (ASD) at a population level has the potential to improve intervention strategies and thus reduce the burden of the disease. In Ontario, Canada, developmental data are regularly collected with the Early Development Instrument (EDI) for all kindergarten children. The behavior in kindergarten of a sub-population of children diagnosed with developmental disabilities by age 9 is investigated here for patterns that may distinguish children with ASD from those with other disorders. Children with later ASD diagnosis had higher scores in kindergarten in cognitive areas but lower scores in social-emotional areas than children with other disabilities, indicating meaningful differences between those groups even before diagnosis. These results support the potential of using the EDI to monitor ASD-like behaviors at the population level.

Patterns of altered neural synchrony in the default mode network in autism spectrum disorder revealed with magnetoencephalography (MEG): Relationship to clinical symptomatology / R. LAJINESS-O'NEILL in Autism Research, 11-3 (March 2018)

Studies exploring brain dynamics to comprehensively characterize and link connectivity to large-scale cortical networks and clinical symptoms are lagging considerably. Patterns of neural coherence within the Default Mode Network (DMN) and Salience Network (SN) during resting state were investigated in 12 children with ASD (MAge = 9.2) and 13 age and gender-matched neurotypicals (NT) (MAge = 9.3) with magnetoencephalography. Coherence between 231 brain region pairs within four frequency bands (theta (4-7 Hz), alpha, (8-12 Hz), beta (13-30 Hz), and gamma (30-80 Hz)) was calculated. Relationships between neural coherence and social functioning were examined. ASD was characterized by lower synchronization across all frequencies, reaching clinical significance in the gamma band. Lower gamma synchrony between fronto-temporo-parietal regions was observed, partially consistent with diminished default mode network (DMN) connectivity. Lower gamma coherence in ASD was evident in cross-hemispheric connections between: angular with inferior/middle frontal; middle temporal with middle/inferior frontal; and within right-hemispheric connections between angular, middle temporal, and inferior/middle frontal cortices. Lower gamma coherence between left angular and left superior frontal, right inferior/middle frontal, and right precuneus and between right angular and inferior/middle frontal cortices was related to lower social/social-communication functioning. Results suggest a pattern of lower gamma band coherence in a subset of regions within the DMN in ASD (angular and middle temporal cortical areas) related to lower social/social-communicative functioning. Autism Res 2018, 11: 434-449. (c) 2017 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: Communication between different areas of the brain was observed in children with ASD and neurotypical children while awake, but not working on a task. Magnetoencephalography was used to measure tiny magnetic fields naturally generated via brain activity. The brains of children with ASD showed less communication between areas that are important for social information processing compared to the brains of neurotypical children. The amount of communication between these areas was associated with social and social communication difficulties.

Longitudinal development of thalamic and internal capsule microstructure in autism spectrum disorder / K. MCLAUGHLIN in Autism Research, 11-3 (March 2018)

LAINHART, Auteur Article en page(s) : p.450-462 Langues : Anglais (eng) Mots-clés : autism spectrum disorder  diffusion magnetic resonance imaging  internal capsule  thalamus  white matter Index. décimale : PER Périodiques Résumé : The thalamus is a key sensorimotor relay area that is implicated in autism spectrum disorder (ASD). However, it is unknown how the thalamus and white-matter structures that contain thalamo-cortical fiber connections (e.g., the internal capsule) develop from childhood into adulthood and whether this microstructure relates to basic motor challenges in ASD. We used diffusion weighted imaging in a cohort-sequential design to assess longitudinal development of the thalamus, and posterior- and anterior-limbs of the internal capsule (PLIC and ALIC, respectively) in 89 males with ASD and 56 males with typical development (3-41 years; all verbal). Our results showed that the group with ASD exhibited different developmental trajectories of microstructure in all regions, demonstrating childhood group differences that appeared to approach and, in some cases, surpass the typically developing group in adolescence and adulthood. The PLIC (but not ALIC nor thalamus) mediated the relation between age and finger-tapping speed in both groups. Yet, the gap in finger-tapping speed appeared to widen at the same time that the between-group gap in the PLIC appeared to narrow. Overall, these results suggest that childhood group differences in microstructure of the thalamus and PLIC become less robust in adolescence and adulthood. Further, finger-tapping speed appears to be mediated by the PLIC in both groups, but group differences in motor speed that widen during adolescence and adulthood suggest that factors beyond the microstructure of the thalamus and internal capsule may contribute to atypical motor profiles in ASD. Autism Res 2018, 11: 450-462. (c) 2017 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: Microstructure of the thalamus, a key sensory and motor brain area, appears to develop differently in individuals with autism spectrum disorder (ASD). Microstructure is important because it informs us of the density and organization of different brain tissues. During childhood, thalamic microstructure was distinct in the ASD group compared to the typically developing group. However, these group differences appeared to narrow with age, suggesting that the thalamus continues to dynamically change in ASD into adulthood.

The present study aimed to describe functioning in ASD (as operationalized by the ICF) derived from the perspectives of diagnosed individuals, family members, and professionals. A qualitative study using focus groups and semi-structured interviews were conducted with 19 stakeholder groups (N = 90) from Canada, India, Saudi Arabia, South Africa, and Sweden. Meaningful concepts from the focus groups and individual interviews were linked to ICF categories using a deductive qualitative approach with standardized linking procedures. The deductive qualitative content analysis yielded meaningful functioning concepts that were linked to 110 ICF categories across all four ICF components. Broad variation of environmental factors and activities and participation categories were identified in this study, while body functions consisted mainly of mental functions. Body structures were sparsely mentioned by the participants. Positive aspects of ASD included honesty, attention to detail, and memory. The experiences provided by international stakeholders support the need to understand individuals with ASD in a broader perspective, extending beyond diagnostic criteria into many areas of functioning and environmental domains. This study is part of a larger systematic effort that will provide the basis to define ICF Core Sets for ASD, from which assessment tools can be generated for use in clinical practice, research, and health care policy making. Autism Res 2018, 11: 463-475. (c) 2017 The Authors Autism Research published by International Society for Autism Research and Wiley Periodicals, Inc. LAY SUMMARY: The study findings support the need to understand the living experiences of individuals with Autism Spectrum Disorder (ASD) from a broader perspective, taking into account many areas of an individual's functioning and environment. The ICF can serve as foundation for exploring these living experiences more extensively by offering tools that enable wide variety of individual difficulties and strengths to be captured along with important environmental influences. As such, these tools can facilitate interventions that meet the needs and goals of the individual.

We additionally suggest that degree of caregiver-clinician agreement on ASD symptoms may play a role in ASD assessment. Since gold standard ASD assessment integrates caregiver-reported developmental history with clinician observations, differential agreement between reporters across demographic groups may contribute to a host of detrimental outcomes. Here, we investigate whether caregiver-clinician agreement on ASD symptoms varies according to child and family characteristics. Comprehensive data from 2,759 families in the Simons Simplex Collection were analyzed. Linear models were created with caregiver reports predicting clinician reports, and moderating effects of child characteristics and family factors were examined. Poorer reporter correspondence was observed when children had higher IQ scores, stronger adaptive behavior, and more behavioral difficulties. Greater disagreement was also associated with African American racial status (for younger children), lower household income, and paternal social difficulties (for older children). Children's biological sex did not moderate caregiver-clinician agreement. Marked disagreement between caregivers and clinicians could lead to suboptimal or insufficient intervention services and negative experiences for families throughout development.

LAY SUMMARY: Evaluation of autism spectrum disorder (ASD) incorporates both caregiver and clinician perspectives of symptoms, and disagreement between these perspectives could lead to poorer outcomes for families. Using data from 2,759 families, we show that caregiver-clinician agreement on ASD symptoms is poorer for children with higher cognitive and adaptive skills, more behavioral difficulties, lower household income, and African American racial status. These children may be at higher risk for misdiagnosis, poorer family experiences during evaluations, and poorer representation in ASD research.

Defining behavioral components of social functioning in adults with autism spectrum disorder as targets for treatment / Ashley A. PALLATHRA in Autism Research, 11-3 (March 2018)  

Public ISBD [article]  inAutism Research > 11-3 (March 2018) . - p.488-502 Titre : Defining behavioral components of social functioning in adults with autism spectrum disorder as targets for treatment Type de document : Texte imprimé et/ou numérique Auteurs : Ashley A.

SCHULTZ, Auteur ; Edward S. BRODKIN, Auteur Article en page(s) : p.488-502 Langues : Anglais (eng) Mots-clés : adult autism spectrum disorder  anxiety  cognition  motivation  skills  social functioning  treatment Index. décimale : PER Périodiques Résumé : There is increasing recognition that adults with autism spectrum disorder (ASD) would benefit from treatment to improve social functioning, a key factor in adults' overall quality of life. However, the various behavioral components of social functioning (i.e., categories of behaviors underlying social functioning), including social motivation, social anxiety, social cognition, and social skills, have not all been assessed together in any sample of adults with ASD, making it difficult to know the relative levels of impairment in these various categories, the relationships among these categories, or promising targets for treatments. We hypothesized there would be significant correlations among measures within the same category, but fewer correlations of measures between categories, indicating the heterogeneity of impairments in adults with ASD. Twenty-nine adults with ASD without co-occurring intellectual disability completed multiple assessments measuring social motivation, social anxiety, social cognition, and social skills, as well as measures of overall ASD symptom levels and community functioning. Results revealed significant positive correlations among measures within most categories; positive correlations between measures of social motivation and all other categories, except for social cognition; as well as positive cross-domain correlations between measures of anxiety and ASD phenotype; measures of social skills and community functioning; and measures of social skills and ASD phenotype. Further studies are warranted to determine causal relationships among these behavioral categories, across developmental stages. However, the lack of correlations between many categories suggests the potential importance of multidimensional treatments that target the particular components of social functioning most in need of improvement in individuals. Autism Res 2018, 11: 488-502. (c) 2017 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: The goal of this study was to measure behaviors that contribute to social functioning difficulties in adults with ASD, with the ultimate goal of guiding treatment development. We found that motivation to interact with others was significantly related to social anxiety and social skill. Our results suggest that motivation may be important to target in treatment, and that treatments should be tailored to the areas most in need of improvement in each individual.

Utility of an abbreviated version of the stanford-binet intelligence scales (5(th) ed.) in estimating 'full scale' IQ for young children with autism spectrum disorder / C. TWOMEY in Autism Research, 11-3 (March 2018)

Set within a public early intervention team service, the current cross-sectional study investigated the utility of the ABIQ in estimating FSIQ for 40 children with autism spectrum disorder (ASD) aged 3-5 years. A strong ABIQ-FSIQ association was yielded (r = 0.89; r(2) = 0.808) and the ABIQ did not over-estimate mean FSIQ above a clinically-relevant threshold; however, clinically significant over-estimation occurred in 17.5% of individual cases. While the findings provide support for the utility of the ABIQ in estimating FSIQ for young children with ASD, caution relating to the over-estimation of FSIQ is warranted. Careful clinical judgment-ideally based on examination of previous cognitive assessment results (if available), thorough interactional observations, and close multi-disciplinary consultation-is necessary to determine the applicability of the ABIQ to individual cases.

Visual Motion Prediction and Verbal False Memory Performance in Autistic Children / F. G. TEWOLDE in Autism Research, 11-3 (March 2018)  

Public ISBD [article]  inAutism Research > 11-3 (March 2018) . - p.509-518 Titre : Visual Motion Prediction and Verbal False Memory Performance in Autistic Children Type de document : Texte imprimé et/ou numérique Auteurs : F.

MANNING, Auteur Article en page(s) : p.509-518 Langues : Anglais (eng) Mots-clés : autism  child development  memory  motion perception  neurodevelopmental disorders  visual perception Index. décimale : PER Périodiques Résumé : Recent theoretical accounts propose that atypical predictive processing can explain the diverse cognitive and behavioral features associated with autism, and that difficulties in making predictions may be related to reduced contextual processing. In this pre-registered study, 30 autistic children aged 6-14 years and 30 typically developing children matched in age and non-verbal IQ completed visual extrapolation and false memory tasks to assess predictive abilities and contextual processing, respectively. In the visual extrapolation tasks, children were asked to predict when an occluded car would reach the end of a road and when an occluded set of lights would fill up a grid. Autistic children made predictions that were just as precise as those made by typically developing children, across a range of occlusion durations. In the false memory task, autistic and typically developing children did not differ significantly in their discrimination between items presented in a list and semantically related, non-presented items, although the data were insensitive, suggesting the need for larger samples. Our findings help to refine theoretical accounts by challenging the notion that autism is caused by pervasively disordered prediction abilities. Further studies will be required to assess the relationship between predictive processing and context use in autism, and to establish the conditions under which predictive processing may be impaired. Autism Res 2018, 11: 509-518. (c) 2017 The Authors Autism Research published by International Society for Autism Research and Wiley Periodicals, Inc. LAY SUMMARY: It has been suggested that autistic individuals have difficulties making predictions and perceiving the overall gist of things. Yet, here we found that autistic children made similar predictions about hidden objects as non-autistic children. In a memory task, autistic children were slightly less confused about whether they had heard a word before, when words were closely related in meaning. We conclude that autistic children do not show difficulties with this type of prediction.

This study examined the efficacy of cognitive enhancement therapy (CET) for improving core cognitive and employment outcomes in adult autism. Verbal adult outpatients with autism spectrum disorder (N = 54) were randomized to an 18-month, single-blind trial of CET, a cognitive remediation approach that integrates computer-based neurocognitive training with group-based training in social cognition, or an active enriched supportive therapy (EST) comparison focused on psychoeducation and condition management. Primary outcomes were composite indexes of neurocognitive and social-cognitive change. Competitive employment was a secondary outcome. Intent-to-treat analyses indicated that CET produced significant differential increases in neurocognitive function relative to EST (d = .46, P = .013). Both CET and EST were associated with large social-cognitive improvements, with CET demonstrating an advantage at 9 (d = .58, P = 0.020), but not 18 months (d = .27, P = 0.298). Effects on employment indicated that participants treated with CET were significantly more likely to gain competitive employment than those in EST, OR = 6.21, P = 0.023, which was mediated by cognitive improvement. CET is a feasible and potentially effective treatment for core cognitive deficits in adult autism spectrum disorder. The treatment of cognitive impairments in this population can contribute to meaningful improvements in adult outcomes. Autism Res 2018, 11: 519-530. (c) 2017 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: Cognitive enhancement therapy (CET), an 18-month cognitive remediation intervention designed to improve thinking and social understanding, was found to be more effective than supportive therapy at improving mental quickness, attention, and employment in adults living with autism. Social understanding was equally improved in CET and supportive therapy. Cognitive remediation interventions are feasible and may confer significant functional benefits to adults with autism.

Is food refusal in autistic children related to TAS2R38 genotype? / M. P. RICCIO in Autism Research, 11-3 (March 2018)  

Public ISBD [article]  inAutism Research > 11-3 (March 2018) . - p.531-538 Titre : Is food refusal in autistic children related to TAS2R38 genotype?

A link between bitter taste perception, namely PROP/PTC sensitivity and food preferences is known in healthy children. The aim of this study is to investigate whether genetic variants of the TAS2R38 taste receptor responsible for different bitter sensitivity could affect foods preferences and consequently food refusal in ASD children. We recruited 43 children with ASD and 41 with normotypic development (TD) with or without food selectivity, aged between 2 and 11 years. Children were characterized for bitter sensitivity by means of PROP strips and FACS analysis and genotyped for TAS2R38 polymorphisms. Food selectivity was assessed by a validated food preference questionnaire filled by parents. A statistically significant correlation between PROP sensitivity and food refusal was observed. Furthermore, a prevalence of the PAV-sensitive haplotype compared to the AVI-insensitive one was seen in ASD children with food selectivity. In agreement with the initial hypothesis the results show that food refusal in ASD children is mediated by bitter taste sensitivity thus suggesting that the bitter sensitivity test may be used as a device to orientate tailored food proposals for the practical management of food selectivity in ASD. Autism Res 2018, 11: 531-538. (c) 2017 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: A variation of the gene TAS2R38, associated with bitter taste sensitivity, can cause a different perception of some foods. In particular, some children are hypersensitive to bitterness and show a more restricted repertoire of accepted foods. We evaluate bitter sensitivity in ASD children with or without food selectivity, through a simple bitter taste test with edible strips. The results show that food refusal in ASD children can be mediated by bitter taste sensitivity thus suggesting that the bitter sensitivity test may be used as a device to orientate tailored food proposals for the practical management of food selectivity in ASD.

Infants were assessed prospectively at 12 and 18 months of age using the clinician administered Autism Observational Scale for Infants (AOSI) and the Autism Parent Screen for Infants (APSI) and underwent a blind independent diagnostic assessment for ASD at 36 months of age. Direct comparison of parent and clinician ratings showed poor agreement on all early behavioral signs, with parent-reported symptoms being better able to differentiate between children with and without ASD at both 12 and 18 months of age compared to clinician observations during a brief office visit. The results suggest that parents may detect some clinically informative behaviors based on their day-to-day observations more readily than do clinicians during brief clinical assessments, a result that needs to be replicated in a non-sibling cohort. Autism Res 2018, 11: 539-547. (c) 2018 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: Parents of children at high-risk of autism spectrum disorder (ASD; have an older sibling with ASD) and clinicians were compared on their reporting of 19 early signs of autism. Direct comparison of parent and clinician ratings showed poor agreement on all early behavioral signs, with parent-reported symptoms being better able to differentiate between children with and without ASD at both 12 and 18 months of age compared to clinician observations during a brief office visit. This suggests that parents may have important information regarding early development of their high-risk child.
