GE, Auteur ; X. XU, Auteur Article en page(s) : p.1206-1217 Langues : Anglais (eng) Mots-clés : Chat-23  China  autism spectrum disorder  community-based  early screening Index. décimale : PER Périodiques Résumé : Most children with autism spectrum disorder (ASD) are not diagnosed until the age of 4, thus missing the opportunity for early intervention. The objective of this study was to investigate the feasibility of an early screening program for ASD applied during well-child visits in a community-based sample. The study lasted for 4 years and was divided into two stages. Stage I involved the implementation of the basic screening model in 2014. Toddlers received level 1 screening via section A of the Chinese-validated version of the Checklist for Autism in Toddlers (CHAT-23) during 18- and 24-month well-child visits in Xuhui District, Shanghai, China. Screen-positive children were referred to receive section B of the CHAT-23 for level 2 screening, and those still screen-positive were referred to undergo diagnosis and evaluation. Stage II involved the implementation of the improved screening model from 2015 to 2017 with the following modifications: (a) an added observational component in level 1 screening; (b) telephone follow-ups with the screen-positive families; and (c) dissemination of information on ASD to families. The results showed that 42 of 22,247 screened children were diagnosed with ASD. The ASD diagnosis rates were 0.1% in Stage I and 0.21% in Stage II. The screen-positive rate and the show rate of referral for level 1 screening increased by 76.92% and 58.43%, respectively, in Stage II compared to Stage I. Our results suggest that with appropriate logistic support, this two-level screening model is feasible and effective for the early screening of ASD during well-child visits. Autism Res 2018, 11: 1206-1217. (c) 2018 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: Difficulty in the timely identification of autism spectrum disorder (ASD) results in missed opportunities for many ASD children to receive early intervention. In this study, we established an early screening model for ASD among children aged 18-24 months in the community by relying on the three-level child healthcare system in China. The results showed that this model can effectively identify and diagnose ASD in children at an early age and thus enable early intervention.

This study utilized diffusion tensor imaging (DTI) and deterministic tractography to map the WM structural networks in 37 ASD toddlers and 27 age-, gender- and developmental quotient-matched controls with developmental delay (DD) toddlers aged 2-3 years old at baseline (Time 1) and at 2-year follow-up (Time 2). Furthermore, graph-theoretical methods were applied to investigate alterations in the network hubs in these patients at the two time points. The results showed that after 2 years, 17 hubs were identified in the ASD subjects compared to the controls, including 13 hubs that had not changed from baseline and 4 hubs that were newly identified. In addition, alterations in the properties of the hubs of the right middle frontal gyrus, right insula, left median cingulate gyri, and bilateral precuneus were significantly correlated with alterations in the behavioral data for ASD patients. These results indicated that at the stage of 2-5 years of age, ASD children showed distributions of network hubs that were relatively stable, with minor differences. Abnormal developmental patterns in the five areas mentioned above in ASD may contribute to abnormalities in the social and nonsocial characteristics of this disorder. Autism Res 2018, 11: 1218-1228.

LAY SUMMARY: This work studied the longitudinal developmental patterns of hubs in the whole-brain white matter (WM) structural network among toddlers with autism spectrum disorder (ASD). The findings of this study could have implications for understanding how the abnormalities in hub organization in ASD account for behavioral deficits in patients and may provide potential biomarkers for disease diagnosis and the subsequent monitoring of progression and treatment effects for patients with ASD.

Do cognitive deficits persist into adolescence in autism? / Cathriona CANTIO in Autism Research, 11-9 (September 2018)

THE AIM OF THIS STUDY WAS TO INVESTIGATE HOW THESE COGNITIVE FUNCTIONS DEVELOP OVER TIME: The three cognitive domains (ToM, EF, and LB) were examined in a group of high-functioning children (age: 8-12, mean 10.85; IQ: 78-139, mean 105.48) with ASD and a matched group of children with neurotypical development (NTD) (IQ: 75-145, mean: 109.47), and several tasks were used within each domain to ensure the validity of the cognitive measures. Approximately 3 years later (mean age: 14.34), all children and their families were invited to participate in the follow-up (ASD, N = 21; NTD, N = 30). While the understanding of other's minds does improve from childhood to adolescence, ToM impairment persists in adolescents with ASD relative to their peers. Likewise, a development in EF was observed in the ASD group, while no significant improvement was seen in the NTD group, leading the ASD group to catch up in this domain. We did not detect any group differences at any time point regarding local bias processing (LB). Individual patterns of development were seen, but remarkably, ToM deficits were present in every child with ASD in whom we could detect any cognitive impairment at baseline, and a similar pattern was found at follow-up. These findings indicate that ToM is a persistent cognitive deficit in ASD. Autism Res 2018, 11: 1229-1238. (c) 2018 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: This was the first study to investigate the development of three well-known cognitive functions into adolescence: While the understanding of other's minds improves from childhood to adolescence, adolescents with ASD are still impaired relative to their peers. The EFs, however, seem to improve to a neurotypical level in ASD as children enter adolescence, while local processing bias seems to differentiate the groups only in early childhood.

Mind perception and moral judgment in autism / Hironori AKECHI in Autism Research, 11-9 (September 2018)

Numerous studies have investigated theory of mind in autism spectrum disorder or how autistic individuals represent the mental states of others. Here, we have examined, as an alternative, mind perception, namely how individuals perceive the minds of various animate and inanimate entities. Autistic and non-autistic participants demonstrated evidence of a similar two-dimensional mind perception; agency, capacity for doing (i.e., self-control, memory, plan), and experience, capacity for feeling (i.e., fear, hunger, pain). Some targets (e.g., human infant and dog) were perceived to have low agency but high experience, while others (e.g., robot and God) were perceived to have the reverse pattern. Moreover, in both autistic and non-autistic groups, the attribution of moral blame positively correlated with agency, whereas moral consideration positively correlated with experience. These results offer new evidence of social cognition, particularly conception of mind and morality, in autism. Autism Res 2018, 11: 1239-1244. (c) 2018 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: We found that autistic and non-autistic individuals have similar thoughts regarding the minds of various living and nonliving entities. In addition, both groups gave moral consideration or blamed entities for wrongdoing according to their conception of the minds of those entities. Autistic individuals have this mind-based moral sense, which is a pivotal element with a key role in human society.

Therefore, they are considered to have visual strength. However, whether people with ASD are cognitively superior in visual processing and what causes the difference between visual and other sensory processing remain unknown. Thus, we compared visual and auditory processing from an aspect of memory in people with ASD and controls. We conducted the Wechsler Memory Scale-Revised (WMS-R) with 64 adults with ASD and 30 controls matched for gender, age, and Full Scale Intelligence Quotient (FIQ). Our results showed that participants with ASD were inferior in visual working memory (P < .01), on a task in which a visual target was pointed every second. Another visual memory, namely, Visual Reproduction in which four geometric figures were presented each by 10 sec, and auditory memory, including working memory, revealed no significant differences between groups. Other visual memory, namely, Visual Paired Associates in which paired presentations were shown every 3 sec, had weak differences (P = .019). Thus, people with ASD might have difficulties processing rapid visual information. Autism Res 2018, 11: 1245-1252. (c) 2018 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: Autistic people are often supported by visual presentations. In this study, we inspected whether they have visual superiority. We showed that they were not visually superior in cognitive aspects, and were poor not at auditory but at visual working memory. Static visual memory in which memorization time is longer than that in working memory was intact in autism. Unusual rapid visual presentation may bother people with autism.

Insistence on sameness and broader autism phenotype in simplex families with autism spectrum disorder / A. N. ESLER in Autism Research, 11-9 (September 2018)

JACOB, Auteur Article en page(s) : p.1253-1263 Langues : Anglais (eng) Mots-clés : broader autism phenotype  insistence on sameness  subphenotypes Index. décimale : PER Périodiques Résumé : Insistence on sameness (IS) in individuals with autism spectrum disorder (ASD) and their families may have utility in identifying meaningful subgroups for studying the pathophysiological and genetic pathways affected in ASD. The primary objectives of the current study were to (1) characterize features of IS in parents of children with ASD and (2) examine their relationships with child IS symptoms. Participants were 2760 families who participated in the Simons Simplex Collection. Levels of parent IS were measured using the Broader Autism Phenotype Questionnaire (BAPQ). A factor analysis generated a BAPQ-IS scale, consisting of a subset of 11 items from the original BAPQ-Rigid scale. Correlations were run to examine the relationship between parent BAP and child IS variables. Correlations were found between parent IS and measures of child IS. Although relationships between parent and child IS features were statistically significant in this large sample, effect sizes were small. Results may be reflective of sample design that only included simplex families, where ASD severity may be predominantly driven by spontaneous mutations and less by common inherited risk from parents. In addition, child and parent measures used may have differentially captured features and severity of IS. Further research is needed on how IS can be accurately measured throughout development and across individuals with ASD and their unaffected family members to facilitate future studies on IS as a possible endophenotype for ASD. Autism Res 2018, 11: 1253-1263. (c) 2018 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: Previous research has suggested that insistence on sameness (IS) may be a heritable trait in autism spectrum disorder (ASD). The study examined whether children with high levels of IS had parents with IS tendencies. A small relationship was found between parent and child measures of IS. Future research is needed on measurement of insistence on sameness across individuals with and without ASD to further examine this relationship and improve understanding of the genetics of ASD.

Autism Res 2018, 11: 1253-1263. (c) 2018 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: Previous research has suggested that insistence on sameness (IS) may be a heritable trait in autism spectrum disorder (ASD). The study examined whether children with high levels of IS had parents with IS tendencies. A small relationship was found between parent and child measures of IS. Future research is needed on measurement of insistence on sameness across individuals with and without ASD to further examine this relationship and improve understanding of the genetics of ASD.

Sex differences in social attention in autism spectrum disorder / Clare HARROP in Autism Research, 11-9 (September 2018)  

Public ISBD [article]  inAutism Research > 11-9 (September 2018) . - p.1264-1275 Titre : Sex differences in social attention in autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Clare HARROP, Auteur ; Desiree R. JONES, Auteur ; Shuting ZHENG, Auteur ; Sallie W. NOWELL, Auteur ; Brian A. BOYD, Auteur ; Noah J. SASSON, Auteur Article en page(s) : p.1264-1275 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Although reduced social attention and increased nonsocial attention have been reported in individuals with autism spectrum disorder (ASD), the studies have relied on predominantly male samples and have been underpowered to examine sex differences. These processes may differ for females with ASD, who have been shown to be dissimilar to males in social motivation and nonsocial features, including circumscribed interests (CI). The goal of this study was to compare social and nonsocial visual attention between males and females with ASD on a validated eye-tracking paradigm. Eighty-five school-aged (6–10 years) males and females with and without ASD completed a paired preference task of face and object stimuli (half of which related to common CI). After covarying for chronological and mental age, the presence of concurrently presented CI images reduced prioritization and attention to faces for males more than females, replicating previous findings. ASD females maintained comparable attention patterns to typically developing females, suggesting that previous findings of reduced social attention and increased attention to CI-related objects in autism may be specific to males. These findings are also inconsistent with the “extreme male brain” theory of autism. The more normative orienting and attention to social stimuli for females with ASD may indicate distinct phenotypic characteristics relative to males and possibly serve as a protective effect. Autism Res 2018, 11: 1264–1275. © 2018 International Society for Autism Research, Wiley Periodicals, Inc. Lay Summary As autism is more commonly diagnosed in males, less is known about females with autism. Two areas of interest include the interests held by individuals with autism and how socially motivated they are. We used eye tracking as a way to understand these two areas. Our data reveal that elementary school-aged females (6–10 years) with autism attended to faces comparatively to females without autism, suggesting that (1) they were more socially motivated than males with autism and (2) the images of common interests were less motivating to them.

Differences in anticipatory versus reactive stress to social evaluative threat in adults versus adolescents with autism / Julie LOUNDS TAYLOR in Autism Research, 11-9 (September 2018)  

Public ISBD [article]  inAutism Research > 11-9 (September 2018) . - p.1276-1285 Titre : Differences in anticipatory versus reactive stress to social evaluative threat in adults versus adolescents with autism Type de document : Texte imprimé et/ou numérique Auteurs : Julie LOUNDS TAYLOR, Auteur ; R. A. MUSCATELLO, Auteur ; B. A. CORBETT, Auteur Article en page(s) : p.1276-1285 Langues : Anglais (eng) Mots-clés : HPA axis  adolescence  adults  autism spectrum disorder  cortisol  stress Index. décimale : PER Périodiques Résumé : Social evaluative threat is a potent activator of the hypothalamic-pituitary-adrenocortical (HPA) axis in typically developing (TD) populations. Studies have shown that children and adolescents with autism spectrum disorder (ASD) show a blunted cortisol response to this type of stressor; yet, a previous study in adults with ASD reported a more prototypical stress response. The current study compared 24 adolescents and 17 adults with ASD to investigate a possible developmental lag in autism resulting in a more adaptive stress response to social evaluation with development. Participants were exposed to the trier social stress test (TSST), and salivary cortisol was collected before and after stress induction. Multilevel modeling revealed that relative to adolescents, young adults with ASD evidenced a significant increase in cortisol in response to anticipatory stress, and 23.5% were classified as anticipatory responders. Adolescents, however, had a significant change in slope in response to the TSST, with 37.5% classified as reactive responders. In both groups, the majority of participants did not have a robust stress response to the TSST as would be expected in TD participants. Findings suggest significant differences in the cortisol trajectory; adults with ASD were more likely to show an anticipatory response to being socially evaluated, which was maintained throughout the stressor, whereas the adolescents had a more reactive response pattern with no anticipatory response. Further research is needed to determine if such patterns are adaptive or deleterious, and to determine underlying factors that may contribute to distinct stress profiles and to the overall diminished stress responses. Autism Res 2018, 11: 1276-1285. (c) 2018 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: Many individuals have increased stress when being socially evaluated. The current study shows that adults with ASD have increased stress in anticipation of a task in which individuals are required to give a speech to unfamiliar raters, while adolescents with ASD tend to show a stress response only during the task itself. Further research is necessary to understand whether developmental influences on stress response in ASD have significant impacts on other areas of functioning often affected by stress.

Oral microbiome activity in children with autism spectrum disorder / S. D. HICKS in Autism Research, 11-9 (September 2018)

MIDDLETON, Auteur Article en page(s) : p.1286-1299 Langues : Anglais (eng) Mots-clés : autism spectrum disorder  developmental delay  gastrointestinal disturbance  microbiome  oropharynx  saliva Index. décimale : PER Périodiques Résumé : Autism spectrum disorder (ASD) is associated with several oropharyngeal abnormalities, including buccal sensory sensitivity, taste and texture aversions, speech apraxia, and salivary transcriptome alterations. Furthermore, the oropharynx represents the sole entry point to the gastrointestinal (GI) tract. GI disturbances and alterations in the GI microbiome are established features of ASD, and may impact behavior through the "microbial-gut-brain axis." Most studies of the ASD microbiome have used fecal samples. Here, we identified changes in the salivary microbiome of children aged 2-6 years across three developmental profiles: ASD (n = 180), nonautistic developmental delay (DD; n = 60), and typically developing (TD; n = 106) children. After RNA extraction and shotgun sequencing, actively transcribing taxa were quantified and tested for differences between groups and within ASD endophenotypes. A total of 12 taxa were altered between the developmental groups and 28 taxa were identified that distinguished ASD patients with and without GI disturbance, providing further evidence for the role of the gut-brain axis in ASD. Group classification accuracy was visualized with receiver operating characteristic curves and validated using a 50/50 hold-out procedure. Five microbial ratios distinguished ASD from TD participants (79.5% accuracy), three distinguished ASD from DD (76.5%), and three distinguished ASD children with/without GI disturbance (85.7%). Taxonomic pathways were assessed using the Kyoto Encyclopedia of Genes and Genomes microbial database and compared with one-way analysis of variance, revealing significant differences within energy metabolism and lysine degradation. Together, these results indicate that GI microbiome disruption in ASD extends to the oropharynx, and suggests oral microbiome profiling as a potential tool to evaluate ASD status. Autism Res 2018, 11: 1286-1299. (c) 2018 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: Previous research suggests that the bacteria living in the human gut may influence autistic behavior. This study examined genetic activity of microbes living in the mouth of over 300 children. The microbes with differences in children with autism were involved in energy processing and showed potential for identifying autism status.

The autism spectrum phenotype in ADNP syndrome / Anne B. ARNETT in Autism Research, 11-9 (September 2018)

EICHLER, Auteur ; Raphael BERNIER, Auteur Article en page(s) : p.1300-1310 Langues : Anglais (eng) Mots-clés : Adnp  autism spectrum disorder  developmental disorder  genetic syndrome  intellectual disability Index. décimale : PER Périodiques Résumé : Pathogenic disruptions to the activity-dependent neuroprotector homeobox (ADNP) gene are among the most common heterozygous genetic mutations associated with autism spectrum disorders (ASDs). Individuals with ADNP disruptions share a constellation of medical and psychiatric features, including ASD, intellectual disability (ID), dysmorphic features, and hypotonia. However, the profile of ASD symptoms associated with ADNP may differ from that of individuals with another ASD-associated single gene disruption or with ASD without a known genetic cause. The current study examined the ASD phenotype in a sample of representative youth with ADNP disruptions. Participants (N = 116, ages 4-22 years) included a cohort with ADNP mutations (n = 11) and three comparison groups with either a mutation to CHD8 (n = 11), a mutation to another ASD-associated gene (other mutation; n = 53), or ASD with no known genetic etiology (idiopathic ASD; n = 41). As expected, individuals with ADNP disruptions had higher rates of ID but less severe social affect symptoms compared to the CHD8 and Idiopathic ASD groups. In addition, verbal intelligence explained more variance in social impairment in the ADNP group compared to CHD8, other mutation, and idiopathic ASD comparison groups. Restricted and repetitive behaviors in the ADNP group were characterized by high levels of stereotyped motor behaviors, whereas the idiopathic ASD group showed high levels of restricted interests. Taken together, these results underscore the role of ADNP in cognitive functioning and suggest that social impairments in ADNP syndrome are consistent with severity of verbal deficits. Autism Res 2018, 11: 1300-1310. (c) 2018 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: Disruptions to the ADNP gene (i.e., ADNP syndrome) have been associated with autism spectrum disorder (ASD). This article describes intellectual disability, mild social difficulties, and severe repetitive motor movements in a group of 11 youth with ADNP Syndrome. We found lower rates of ASD than previously reported. Verbal skills explained individual variability in social impairment. This pattern suggests that the ADNP gene is primarily associated with learning and memory, and level of social difficulties is consistent with level of verbal impairment.
