Why do we need sex-balanced studies of autism? / Christine Wu NORDAHL in Autism Research, 16-9 (September 2023)

The result is that autistic females are understudied. There is a critical need to increase our understanding of autistic females, both biologically and clinically. The only way to do this is to recruit sex-balanced cohorts in studies so that similarities and differences between males and females can be evaluated in all autism research studies. The purpose of this commentary is to (1) provide historical context about how females came to be under-represented in all research, not just in the field of autism and (2) learn from other areas of health and medicine about the potentially dire consequences of not studying both sexes, and (3) draw attention to the need to recruit sex-balanced cohorts in autism research, particularly in neuroimaging studies.

Predicting self-injurious behavior at age three among infant siblings of children with autism / Adele F. DIMIAN in Autism Research, 16-9 (September 2023)  

Public ISBD [article]  inAutism Research > 16-9 (September 2023) . - p.1670-1680 Titre : Predicting self-injurious behavior at age three among infant siblings of children with autism Type de document : Texte imprimé et/ou numérique Auteurs : Adele F. DIMIAN, Auteur ; Annette M. ESTES, Auteur ; Stephen DAGER, Auteur ; Joseph PIVEN, Auteur ; Jason J. WOLFF, Auteur ; for the IBIS NETWORK, Auteur Article en page(s) : p.1670-1680 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Abstract Existing research suggests that self-injurious behavior (SIB) is a relatively common interfering behavior that can occur across the lifespan of individuals with autism spectrum disorder (ASD). We previously reported that SIB or proto-injurious SIB at 12?months was related to increased risk of SIB at 24?months among a preschool sample of children with a high familial likelihood for ASD (Dimian et al., 2017). In the present study, we extend these findings, examine SIB occurrence, and associated potential risk factors at 36?months. The present sample included 149 infants with an older sibling with ASD (65.8% male) who completed assessments at ages 12, 24, and 36?months. Descriptive analyses and binary logistic regression models were utilized. SIB was more prevalent among those children who received a diagnosis of ASD. Logistic regression indicated that presence of SIB, stereotypy, hyper- and hypo- sensory responsivity, and lower intellectual functioning at age 12?months significantly predicted the occurrence of SIB at 36?months. These findings have implications for understanding developmental processes culminating in persistent SIB and may inform prevention programming.

The developmental trajectory of functional excitation-inhibition balance relates to language abilities in autistic and allistic children / Hannah PLUECKEBAUM in Autism Research, 16-9 (September 2023)  

Public ISBD [article]  inAutism Research > 16-9 (September 2023) . - p.1681-1692 Titre : The developmental trajectory of functional excitation-inhibition balance relates to language abilities in autistic and allistic children Type de document : Texte imprimé et/ou numérique Auteurs : Hannah PLUECKEBAUM, Auteur ; Lars MEYER, Auteur ; Ann-Kathrin BECK, Auteur ; Katharina H. MENN, Auteur Article en page(s) : p.1681-1692 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Abstract Autism is a neurodevelopmental condition that has been related to an overall imbalance between the brain's excitatory (E) and inhibitory (I) systems. Such an EI imbalance can lead to structural and functional cortical deviances and thus alter information processing in the brain, ultimately giving rise to autism traits. However, the developmental trajectory of EI imbalances across childhood and adolescence has not been investigated yet. Therefore, its relationship to autism traits is not well understood. In the present study, we determined a functional measure of the EI balance (f-EIB) from resting-state electrophysiological recordings for a final sample of 92 autistic children from 6 to 17?years of age and 100 allistic (i.e., non-autistic) children matched by age, sex, and nonverbal-IQ. We related the developmental trajectory of f-EIB to behavioral assessments of autism traits as well as language ability. Our results revealed differential EI trajectories for autistic compared to allistic children. Importantly, the developmental trajectory of f-EIB values related to individual language ability. In particular, elevated excitability in late childhood and early adolescence was linked to decreased listening comprehension. Our findings provide evidence against a general EI imbalance in autistic children when correcting for non-verbal IQ. Instead, we show that the developmental trajectory of EI balance shares variance with autism trait development at a specific age range. This is consistent with the proposal that the late development of inhibitory brain activity is a key substrate of autism traits.

Sex differences of the triple network model in children with autism: A resting-state fMRI investigation of effective connectivity / Cuicui LI in Autism Research, 16-9 (September 2023)

Gender incoherence (GI) theory suggests that ASD is more neurally androgynous than same-sex controls. Given its central role, altered structures and functions, and sex-dependent network differences in ASD, the triple network model, including the central executive network (CEN), default mode network (DMN), and salience network (SN), has emerged as a candidate for characterizing this sex difference. Here, we measured the sex-related effective connectivity (EC) differences within and between these three networks in 72 children with ASD (36 females, 8-14?years) and 72 typically developing controls (TCs) (36 females, 8-14?years) from 5 sites of the Autism Brain Imaging Data Exchange repositories using a 2?*?2 analysis of covariance factorial design. We also assessed brain-behavior relationships and the effects of age on EC. We found significant diagnosis-by-sex interactions on EC: females with ASD had significantly higher EC than their male counterparts within the DMN and between the SN and CEN. The interaction pattern supported the GI theory by showing that the higher EC observed in females with ASD reflected a shift towards the higher level of EC displayed in male TCs (neural masculinization), and the lower EC seen in males with ASD reflected a shift towards the lower level of EC displayed in female TCs (neural feminization). We also found significant brain-behavior correlations and significant effects of age on EC.

Joint intention understanding in children with autism spectrum disorder / Wenwen HOU in Autism Research, 16-9 (September 2023)

Children were presented with a series of videos in which two actors either played with blocks based on joint intention (social condition) or played with blocks independently (nonsocial condition). In the familiarization stage, two actors demonstrated how they played with blocks three times. In the test stage, one actor left the scene, and another actor grasped a block and asked where she should place it. Children's gaze behavior was assessed by an eye tracker. After watching videos, children were asked to answer two questions: an action prediction question and an intention understanding question. The results showed that in the implicit eye movement task, children with ASD and typically developing (TD) children exhibited location-based anticipatory gaze under both conditions. However, in terms of explicit behavioral responses, TD children showed higher accuracy in response to action prediction questions and intention understanding questions than children with ASD in the social condition, while no significant group difference was found in the nonsocial condition. These results indicate that children with ASD have difficulty understanding joint intention and that their action prediction is primarily driven by bottom-up sensory inputs.

Speech-in-noise perception in autistic adolescents with and without early language delay / Diego RUIZ CALLEJO in Autism Research, 16-9 (September 2023)

Potential aggravating factors are the level of linguistic skills and impairments in auditory temporal processing. Here, we investigated autistic adolescents with and without language delay as compared to non-autistic peers, and we assessed speech perception in steady-state noise, temporally modulated noise, and concurrent speech. We found that autistic adolescents with intact language capabilities and not those with language delay performed worse than NT peers on words-in-stationary-noise perception. For the perception of sentences in stationary noise, we did not observe significant group differences, although autistic adolescents with language delay tend to perform worse in comparison to their TD peers. We also found evidence for a robust deficit in speech-in-concurrent-speech processing in ASD independent of language ability, as well as an association between early language delay in ASD and inadequate temporal speech processing. We propose that reduced voice stream segregation and inadequate social attentional orienting in ASD result in disproportional informational masking of the speech signal. These findings indicate a speech-in-speech processing deficit in autistic adolescents with broad implications for the quality of social communication.

Differences in self-other control as cognitive mechanism to characterize theory of mind reasoning in autistic and non-autistic adults / Tobias SCHUWERK in Autism Research, 16-9 (September 2023)

Yet, recent evidence, showing comparable Theory of Mind abilities in autistic and non-autistic people, draws a more complex picture and renders previous descriptions of Theory of Mind abilities in autism and their role in autistic symptomatology insufficient. Here, we addressed self-other control as a potential candidate cognitive mechanism to explain subtle Theory of Mind reasoning differences between autistic and non-autistic adults. We investigated flexible shifting between another's and one's own congruent or incongruent points of view, an ability that is important for reciprocal social interaction. Measuring response accuracy and reaction time in a multiple-trial unexpected location false belief task, we found evidence for altered self-other control in Theory of Mind reasoning in autistic adults, with a relative difficulty in flexibly considering the other's perspective and less interference of the other's incongruent viewpoint when their own perspective is considered. Our results add to previous findings that social cognitive differences are there but subtle and constitute one step further in characterizing Theory of Mind reasoning in autism and explaining communication and interaction difficulties with non-autistic people in everyday life.

COHENOUR, Auteur ; Amanda GULSRUD, Auteur ; Connie KASARI, Auteur Article en page(s) : p.1739-1749 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Abstract Evidence suggests autistic individuals at elevated familial likelihood of autism spectrum disorder (by virtue of having an autistic sibling) have stronger cognitive abilities on average than autistic individuals with no family history of the condition, who have a low familial likelihood of autism. Investigating phenotypic differences between community-referred infants and toddlers with autism symptoms at elevated or low familial likelihood of autism may provide important insight into heterogeneity in the emerging autism phenotype. This study compared behavioral, cognitive, and language abilities of community-referred infants and toddlers with confirmed autism symptoms at elevated (EL) or low familial likelihood of autism (LL). Participants were 121 children aged 12 to 36?months who participated in two larger randomized trials of parent-mediated interventions for children with autism symptoms. Behavioral phenotypes were compared across three groups: children with at least one autistic sibling (EL-Sibs, n=30), those with at least one older, non-autistic sibling and no family history of autism (LL-Sibs, n=40), and first-born children with no family history of autism (LL-FB, n=51). EL-Sibs had less severe autism symptoms and stronger cognitive abilities than children in LL groups. While the rate of receptive language delay was similar across groups, the rate of expressive language delay was markedly lower among EL-Sibs. After controlling for age and nonverbal cognitive ability, EL-Sibs were significantly less likely to present with expressive language delay than LL-Sibs. Familial likelihood of autism may play an important role in shaping the emerging autism phenotype in infancy and toddlerhood.

No differences in implicit hand maps among different degrees of autistic traits / Souta HIDAKA in Autism Research, 16-9 (September 2023)

LONGO, Auteur ; Makoto WADA, Auteur Article en page(s) : p.1750-1764 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Abstract People with autism spectrum disorder (ASD) or higher levels of autistic traits have atypical characteristics in sensory processing. Atypicalities have been reported for proprioceptive judgments, which are tightly related to internal bodily representations underlying position sense. However, no research has directly investigated whether self-bodily representations are different in individuals with ASD. Implicit hand maps, estimated based on participants' proprioceptive sensations without sight of their hand, are known to be distorted such that the shape is stretched along the medio-lateral hand axis even for neurotypical participants. Here, with the view of ASD as falling on a continuous distribution among the general population, we explored differences in implicit body representations along with autistic traits by focusing on relationships between autistic traits and the magnitudes of the distortions in implicit hand maps (N?~?100). We estimated the magnitudes of distortions in implicit hand maps both for fingers and hand surfaces on the dorsal and palmar sides of the hand. Autistic traits were measured by questionnaires (Autism Spectrum [AQ] and Empathy/Systemizing [EQ-SQ] Quotients). The distortions in implicit hand maps were replicated in our experimental situations. However, there were no significant relationships between autistic traits and the magnitudes of the distortions as well as within-individual variabilities in the maps and localization performances. Consistent results were observed from comparisons between IQ-matched samples of people with and without a diagnosis of ASD. Our findings suggest that there exist perceptual and neural processes for implicit body representations underlying position sense consistent across levels of autistic traits.

Autism, pets, and the importance of seeing human / Gray ATHERTON in Autism Research, 16-9 (September 2023)

Anthropomorphism is particularly prolific regarding the humanization of pets. Some research suggests that people with autism may not anthropomorphize to the same degree as neurotypicals. In this study, we explored whether there were differences in how autistic and neurotypical pet owners anthropomorphized their pets. We also examined differences in levels of connectedness to nature and experiences of loneliness and how this corresponded to autistic traits in the entire sample. We found anthropomorphism was as common among autistic pet owners as in neurotypicals. However, autistic pet owners reported greater loneliness and were more likely to substitute pets for people. We also found that neurotypical pet owners rated pets more highly on physical, non-anthropomorphic traits (i.e., muscular, active). In contrast, autistic pet owners were likelier to rate pets equally between physical and anthropomorphic traits. Moreover, we found that anthropomorphism and connection to nature were positively correlated with autistic traits. These findings challenge accounts stating that individuals with autism may not anthropomorphize to the same degree as neurotypicals. Implications for animal-based interventions supporting adults on the spectrum are discussed.

No evidence for high inflexible precision of prediction errors in autism during lexical processing / Philippa L. HOWARD in Autism Research, 16-9 (September 2023)

This study tested an approach to autistic cognition that suggests learning occurs via prediction errors, and autistic people have very precise and inflexible predictions that result in more sensitivity to meaningless signal errors than non-autistic readers. We used this theoretical background to investigate whether differences in prediction coding influence how orthographic (Experiment 1) and semantic information (Experiment 2) is processed by autistic readers. Experiment 1 used a lexical decision task to test whether letter position information was processed less flexibly by autistic than non-autistic readers. Three types of letter strings: words, transposed letter and substituted letters nonwords were presented. Experiment 2 used a semantic relatedness task to test whether autistic readers processed words with high and low semantic diversity differently to non-autistic readers. Results showed similar transposed letter and semantic diversity effects for all readers; indicating that orthographic and semantic information are processed similarly by autistic and non-autistic readers; and therefore, differences in prediction coding were not evident for these lexical processing tasks.

Nonlinear features of gaze behavior during joint attention in children with autism spectrum disorder / Hongan WANG in Autism Research, 16-9 (September 2023)  

Public ISBD [article]  inAutism Research > 16-9 (September 2023) . - p.1786-1798 Titre : Nonlinear features of gaze behavior during joint attention in children with autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Hongan WANG, Auteur ; Xin ZHAO, Auteur ; Dongchuan YU, Auteur Article en page(s) : p.1786-1798 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Abstract Since children with autism spectrum disorder (ASD) might exhibit a variety of aberrant response to joint attention (RJA) behaviors, there is growing interest in identifying robust, reliable and valid eye-tracking metrics for determining differences in RJA behaviors between typically developing (TD) children and those with ASD. Previous eye-tracking studies have not been deeply investigated nonlinear features of gaze time-series during RJA. As a main motivation, this study aimed to extract three nonlinear features (i.e., complexity, long-range correlation, and local instability) of gaze time-series during RJA in children with ASD, which can be measured by fractal dimension (FD), Hurst exponent (H), and largest Lyapunov exponent (LLE), respectively. To illustrate our idea, this study adopted a publicly accessible database, including eye-tracking data collected during RJA from 19 children with ASD (7.74?+?2.73) and 30 TD children (8.02?+?2.89), and conducted a battery of nonparametric analysis of covariance (ANCOVA), where gender was used as covariable. Findings showed that gaze time-series during RJA in autistic children may generally have greater FD but lower H than that in TD controls. This implies that children with ASD possess more complex and unpredictable gaze behaviors during RJA than TD children. Furthermore, nonlinear metrics outperformed traditional eye-tracking metrics in obtaining higher identification performance with an accuracy of 82% and an AUC value of 0.81, distinguishing the differences between successful and failed RJA trails, and predicting the severity of ASD symptoms. Findings might bring some new insights into the understanding of the impairments in RJA behaviors for children with ASD.

Observational learning of atypical biological kinematics in autism / Nathan C. FOSTER in Autism Research, 16-9 (September 2023)

HAYES, Auteur Article en page(s) : p.1799-1810 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Abstract Observing and voluntarily imitating the biological kinematics displayed by a model underpins the acquisition of new motor skills via sensorimotor processes linking perception with action. Differences in voluntary imitation in autism could be related to sensorimotor processing activity during action-observation of biological motion, as well as how sensorimotor integration processing occurs across imitation attempts. Using an observational practice protocol, which minimized the active contribution of the peripheral sensorimotor system, we examined the contribution of sensorimotor processing during action-observation. The data showed that autistic participants imitated both the temporal duration and atypical kinematic profile of the observed movement with a similar level of accuracy as neurotypical participants. These findings suggest the lower-level perception-action processes responsible for encoding biological kinematics during the action-observation phase of imitation are operational in autism. As there was no task-specific engagement of the peripheral sensorimotor system during observational practice, imitation difficulties in autism are most likely underpinned by sensorimotor integration issues related to the processing of efferent and (re)afferent sensorimotor information during trial-to-trial motor execution.

Physical activity intervention for core symptoms of ASD were retrieved by computer from the PubMed Cochrane Library, Web of Science, APA PsycNet, and CNKI database during December 1, 2022. Two researchers evaluated the quality of the included literature and extracted the data. Sixteen studies were eventually included, with a total of 587 patients with ASD. Meta-analysis showed that the core symptoms of ASD patients decreased after physical activity intervention, ES(g)=0.681(95% CI: 0.380-0.982, p=0.000), specifically, physical activity improved the reduction of social disorder ES(g)=0.749(95% CI: 0.524-0.973) and repeated rigid behavior ES(g)=0.553 (95% CI: ?0.079 to 1.186). Subgroup analysis showed that preschool children with ASD who were 3-6?years old, exercised for more than 12?weeks, more than 3 times a week, and exercised for more than 90?min per session had better improvement in core symptoms after participating in physical activity. The conclusion of this paper is that physical activity intervention can improve the core symptoms of ASD, especially the reduction of social disorders and repetitive behaviors.

CROEN, Auteur ; program collaborators for Environmental influences on Child Health OUTCOMES, Auteur Article en page(s) : p.1825-1835 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Abstract This study evaluated the association between prenatal depression and offspring autism-related traits. The sample comprised 33 prenatal/pediatric cohorts participating in the Environmental influences on Child Health Outcomes program who contributed information on prenatal depression and autism-related traits. Autism-related traits were assessed continuously and at the diagnostic cut-off using the Social Responsiveness Scale for children up to 12?years of age. Main analyses included 3994 parent-child pairs with prenatal depression diagnoses data; secondary analyses included 1730 parent-child pairs with depression severity data. After confounder adjustment, we observed an increase in autism-related traits among children of individuals with prenatal depression compared to those without (adjusted ?=1.31 95% CI: 0.65, 1.98). Analyses stratified by child sex documented a similar significant association among boys (a?=1.34 95%CI: 0.36, 2.32) and girls (a?=1.26 95% CI: 0.37, 2.15). Prenatal depression was also associated with increased odds of moderate to severe autism-related traits (adjusted odds ratio: 1.64, 95%CI: 1.09, 2.46), the screening threshold considered high risk of autism spectrum disorder (ASD) diagnosis. Findings highlight the importance of prenatal depression screening and preventive interventions for children of pregnant individuals with depression to support healthy development. Future research is needed to clarify whether these findings reflect overlap in genetic risk for depression and ASD-related traits or another mechanism.

The sample comprised 33 prenatal/pediatric cohorts participating in the Environmental influences on Child Health Outcomes program who contributed information on prenatal depression and autism-related traits. Autism-related traits were assessed continuously and at the diagnostic cut-off using the Social Responsiveness Scale for children up to 12?years of age. Main analyses included 3994 parent-child pairs with prenatal depression diagnoses data; secondary analyses included 1730 parent-child pairs with depression severity data. After confounder adjustment, we observed an increase in autism-related traits among children of individuals with prenatal depression compared to those without (adjusted ?=1.31 95% CI: 0.65, 1.98). Analyses stratified by child sex documented a similar significant association among boys (a?=1.34 95%CI: 0.36, 2.32) and girls (a?=1.26 95% CI: 0.37, 2.15). Prenatal depression was also associated with increased odds of moderate to severe autism-related traits (adjusted odds ratio: 1.64, 95%CI: 1.09, 2.46), the screening threshold considered high risk of autism spectrum disorder (ASD) diagnosis. Findings highlight the importance of prenatal depression screening and preventive interventions for children of pregnant individuals with depression to support healthy development. Future research is needed to clarify whether these findings reflect overlap in genetic risk for depression and ASD-related traits or another mechanism.

Risk factors and clinical characteristics of autism spectrum disorder with regression in China / Lu HAN in Autism Research, 16-9 (September 2023)  

Public ISBD [article]  inAutism Research > 16-9 (September 2023) . - p.1836-1846 Titre : Risk factors and clinical characteristics of autism spectrum disorder with regression in China Type de document : Texte imprimé et/ou numérique Auteurs : Lu HAN, Auteur ; Luyang GUAN, Auteur ; Ziyi ZHANG, Auteur ; Wenqing LI, Auteur ; Jinhui LI, Auteur ; Chenxi BAO, Auteur ; Mei YE, Auteur ; Min TANG, Auteur ; Xiaoyan KE, Auteur Article en page(s) : p.1836-1846 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Abstract Autism spectrum disorder with regression (ASD-R) is characterized by the loss of previously acquired skills during the initial year of life. This study aimed to investigate the clinical characteristics, patterns of regression, and potential risk factors associated with ASD-R in the Chinese Han population. A case-control study was conducted between September 2020 and March 2022. A total of 186 children were enrolled, including 58 children with ASD-R, 70 with ASD without regression (ASD-NR), and 58 typically developing children. Demographic information, clinical characteristics, and potential risk factors related to ASD-R were assessed using a combination of questionnaires, interviews, and physician assessments. The results revealed that children with ASD-R exhibited more severe impairments in social communication and stereotyped behaviors compared with those with ASD-NR. Language regression, constituting 40% of cases within the ASD-R group, was found to be the most common type of regression. Furthermore, our analysis revealed that fever (OR=4.01, 95% CI: 1.26-12.76) and diarrhea (OR=6.32, 95% CI: 1.38-29.03) were identified as significant risk factors for ASD-R. These findings contribute to our understanding of the heterogeneity of ASD and highlight the importance of considering immune responses and gastrointestinal factors in the etiology of ASD-R.
