To investigate the association between exposure to anesthesia during three periods of pregnancy, delivery, and childhood and autism spectrum disorder (ASD). PubMed, Scopus, Web of Science, Embase, Google Scholar, PsycArticles, and PsycINFO were searched from the date of database inception to 1 December 2022. Studies reported the association between exposure to anesthesia during pregnancy, delivery, and childhood and ASD were included. Extracted variables included hazard ratio (HR), relative risk or odds ratio, standard error, and 95% confidence interval (CI). Effect estimates were pooled using random-effects meta-analysis. In total, 16 studies including 8,156,608 individuals were included in the meta-analysis. Labor epidural anesthesia during delivery was associated with ASD in the general population (adjusted HR = 1.16, 95% CI, 1.06-1.28) but not in the sibling population (adjusted HR = 1.06, 95% CI, 0.98-1.15). Other anesthesia during delivery was not associated with ASD (general population: adjusted HR = 1.08, 95% CI, 0.99-1.17; sibling population: adjusted HR = 1.20, 95% CI, 0.81-1.79). Three studies suggested that exposure to anesthesia during pregnancy was associated with ASD in offspring (adjusted HR = 2.15, 95% CI, 1.32-3.48). There was no significant association between exposure to general anesthesia during childhood and ASD (adjusted HR = 1.02, 95% CI, 0.60-1.72). This meta-analysis did not confirm the association between exposure to anesthesia during labour and ASD. Previous observational studies used the neurotoxicity of anesthesia to biologically explain significant associations, but in fact different controls for confounding factors led to differences in associations. The evidence for pregnancy and childhood was limited given the small number of studies in these periods.

Exercise intervention has been proven helpful to ameliorate core symptoms of Autism Spectrum Disorder (ASD). However, the underlying mechanisms are not fully understood. In this study, we carried out a 12-week mini-basketball training program (MBTP) on ASD children and examined the changes of brain functional and structural networks before and after exercise intervention. We applied individual-based method to construct functional network and structural morphological network, and investigated their alterations following MBTP as well as their associations with the change in core symptom. Structural MRI and resting-state functional MRI data were obtained from 58 ASD children aged 3-12 years (experiment group: n = 32, control group: n = 26). ASD children who received MBTP intervention showed several distinguishable alternations compared to the control without special intervention. These included decreased functional connectivity within the sensorimotor network (SM) and between SM and the salience network, decreased morphological connectivity strength in a cortical-cortical network centered on the left inferior temporal gyrus, and a subcortical-cortical network centered on the left caudate. Particularly, the aforementioned functional and structural changes induced by MBTP were associated with core symptoms of ASD. Our findings suggested that MBTP intervention could be an effective approach to improve core symptoms in ASD children, decrease connectivity in both structure and function networks, and may drive the brain change towards normal-like neuroanatomy.

Psychosexual functioning is an important aspect of human development and relationships. A previous study investigated psychosexual functioning of autistic adolescents using the Teen Transition Inventory (TTI), but there is a lack of comprehensive measurement of psychosexual functioning among autistic and non-autistic (NA) adults. To address this gap, the current study adapted the self-report TTI to the Psychosexual Functioning Survey (PSFS) and presented it to 131 autistic (n = 59) and NA adults (n = 72) in the U.S. Comparisons of psychometric properties between the original TTI and the PSFS are shared; the developmental relevancy among some items was changed, and the alphas indicated a difference in the content of certain scales. Differences emerged between autistic and NA adults in both the intra- and interpersonal domains of psychosexual functioning, but not in sexual and intimate behaviors. The findings suggest the persistence of differences from adolescence to adulthood between autistic and NA people and highlight the importance of understanding the unique experiences of adults in psychosexual functioning relative to diagnostic status.

Purpose: Relative clauses present a well-known processing asymmetry between object-extracted and subject-extracted dependencies across both typical and atypical populations. The present study aimed at exploring the comprehension of object and subject relative clauses as conceptualized by the Relativized Minimality framework in autistic children and in a group of age- and IQ-matched typically-developing children. The study also explored the way performance in relative clauses would be affected by the children's language and executive function skills.

Method: Relative clause comprehension was tested through a sentence-picture matching task and language was tested with a receptive vocabulary task. Executive functions were assessed through backward digit recall and a Flanker test.

Results: Object relative clauses were harder to parse for both groups than subject relatives, while number mismatch between the moved object Noun Phrase and the intervening subject Noun Phrase in object relatives boosted both groups' performances. Typically-developing children's performance in object relatives was predicted by both language and executive functions, while autistic children failed to use language and did not systematically draw on their executive functions in object relative clause comprehension.

Conclusion: The findings suggest that relative clause processing in autism follows a normal developmental trajectory, and that difficulty with parsing object relative clauses stems from reduced language and executive functions rather than deficits in the children's morphosyntactic skills.

Purpose: Internalizing conditions, such as anxiety and depression, and difficulties with developing and maintaining friendships are common among autistic children and adolescents. Participation in extracurricular activities may buffer against these challenges as they provide naturalistic opportunities to bring peers with shared interests and skills together. As such, the purpose of the current study was to examine associations between sport and club participation and (1) friendship success and (2) co-occurring anxiety and depression in a large sample of autistic youth.

Methods: Secondary analysis was performed using data from the 2018-2019 National Survey of Children's Health. Participants were 562 autistic children (ages 6-11 years) and 818 autistic adolescents (ages 12-17 years). Within each age group, a series of binary logistic regression analyses were conducted.

Results: Club participation was not associated with friendship or internalizing conditions. However, participation in sports was positively associated with friendship success among both children (OR = 2.07, p = .006) and adolescents (OR = 2.35, p = .001). Results also found that adolescents who participated in sports were 34% less likely to have diagnosis of depression (p = .048).

Conclusion: Findings suggest that participation in sports may play a meaningful role in protecting against depression during adolescence and serve as a context for friendship development across childhood and adolescence. Future research should address barriers to extracurricular activity participation and identify the specific components of sports that are most beneficial to autistic youth to inform activity offerings and the development of interventions targeting friendship formation and mental health outcomes.

Caring for children with different developmental trajectories brings various challenges, which are often exacerbated in low-resource settings. International research has shown that raising a child with autism strongly impacts family caregivers, particularly mothers. There is a dearth of information regarding caregiving for individuals with autism in the Kurdistan Region of Iraq (KRI) and for fathers as well as mothers. This study examined the similarities and differences in caregiving for mothers and fathers of a child with autism in KRI using validated rating scales to measure various aspects of their general well-being. Over two years, a sample of 118 parents of individuals with autism (81 mothers and 37 fathers) self-completed the rating scales, which were further discussed through individual interviews with service personnel mainly known to them. The findings indicated that mothers and fathers were similarly impacted. Although there were no statistically significant differences in the ratings of their general health, sources of stress, family functioning, and satisfaction with caregiving, the majority of parents had elevated ratings on all the measures. In addition, parents who rated their children higher on the Aberrant Behavior Checklist had significantly higher scores on their general health issues and were less satisfied with their caregiving role. Parents of female individuals with autism were also significantly more stressed compared to the male individuals with autism and parents of children who received a diagnosis before three years of age, reported fewer behavioral problems with their child compared to the parents who received a diagnosis when the child was older. In this sample, mothers and fathers seem to be similarly impacted by caring for a child with autism, which is contrary to findings from other countries. However, in this region, family bonds between couples and the wider family may have had an influence which further cross-cultural research in low-resource settings could help elucidate, notwithstanding the challenges this poses. The findings have policy implications for health authorities in the KRI to improve the support provided to both mothers and fathers who care for children with autism, which presently is rarely available to them.

This paper presents quantitative and qualitative findings from an interdisciplinary research project exploring student teachers' positive perceptions of people on the autism spectrum. The set of findings reported in this paper asked 704 student teachers from one university in England (n = 191), Finland (n = 251) and Sweden (n = 262) to write down the first three words they thought of to identify the characteristics of people on the autism spectrum. Data was analysed using a multi-layered, deductive co-rated coding approach. Through this approach repeated words were extracted as were negative and undetermined words, leaving only positive words. Examination of the positive words identified found differences in the manner student teachers focus on the positive characteristics of people on the autism spectrum as this is an understudied area of research. Finnish student teachers more frequently used language to describe the positive characteristics of people on the autism spectrum that reflected their perception of learning being their primary professional role. However, English and Swedish student teachers used language that showed they perceived their role as encompassing the social and emotional development of their pupils, with little reflection about the positive characteristics of people on the autism spectrum as learners.

Since autism diagnosis is directly linked to the availability of supportive services, identifying best practices for early diagnosis of autism has long been a concern of professionals and families. Meanwhile, studies show persistent racial disparities in autism diagnosis. Although numerous clinical diagnostic guidelines have been published, there is not enough discussion of diagnostic procedures through the lens of culturally diverse families.

Purpose: This study focuses on the autism diagnostic experiences that Korean immigrant mothers had with their children.

Methods: Eleven first-generation Korean-American mothers of children with autism were included in the study. The data was collected using semi-structured interviews in Korean.

Results: The main five factors (i.e., cultural beliefs and values, language barriers, complex emotions, immigration and navigating systems, and facilitators and assets) that mainly influence the diagnosis process were identified through thematic analysis.

Conclusion: Dynamics are interactive within and between the factors, influencing the entire diagnostic process by either delaying or facilitating the identification of a child's autism and the provision of treatment.

Objective: Attention Deficit Hyperactivity Disorder (ADHD) is a common co-occurring condition in autistic individuals. ADHD is sometimes first recognised in young adulthood because ADHD symptoms may be misattributed to autism due to superficial overlap in presentation and diagnostic overshadowing. It should be investigated whether ADHD questionnaires are accurate in screening symptoms in young adults with autism. The current study examined this.

Methods: Participants were autistic young adults (N = 119) who took part in the Special Needs and Autism Project (SNAP), a population-based cohort. ADHD research diagnoses were obtained through the parent-informed Young Adult Psychiatric Assessment. Parents and young adults (self-report sample N = 71) completed ADHD questionnaires (Aberrant Behavior Checklist hyperactivity/non-compliance subscale, Conners Adult ADHD Rating Scales ADHD Index, and Strengths and Difficulties Questionnaire ADHD subscale). Receiver operating characteristic analyses were conducted to explore if the questionnaires discriminated ADHD cases from non-cases. To assess whether results varied by intellectual functioning, subgroup analyses were completed for those with an IQ ≥ 70 vs. <70.

Results: Weighted ADHD rates were high. Overall although the measures were performing at or close to adequate levels (area under the curve was 0.66 to 0.79 for parent-report and 0.70 to 0.65 for self-report), no single measure met adequate thresholds for sensitivity and specificity simultaneously. Tool performance was not different for those with an IQ ≥ 70 vs. <70.

Conclusion: No single measure reported adequate performance for distinguishing ADHD from non-ADHD cases in this sample of young autistic adults. Use of current thresholds may lead to under-diagnosis.

This systematic literature review discusses the use of spherical video-based virtual reality (SVVR) as a training and therapy intervention for autistic individuals. The authors emphasize the need for an evidence-based framework with guidelines and design considerations to help developers and educators tailor SVVR to the diverse needs of autistic learners. The paper highlights the unique benefits of SVVR, such as being relatively easier to develop compared to other VR technologies and high compatibility with various devices, making it more affordable for educational settings. The authors also discuss the importance of the STP (Sociotechnical-Pedagogical) framework for evaluating and designing social aspects of SVVR interventions for autistic individuals.
