This study provided empirical evaluation of the theoretical model by Kennedy and Adolphs (2012) positing that social competence relies on an interconnected network of four components: social brain, cognition, behavior, and functioning. Data from 243 youth (69 female, 174 male), age 10-17 years, were used to test the hypothesized mediation effect of social cognition (Theory of Mind) from social brain (event-related potential markers of face perception and memory) to social behavior (Contextual Assessment of Social Skills) and functioning (Child Behavior Checklist). An additional analysis evaluated whether the structure of the social competence model varied based on the biological sex of the autistic participants. The findings support the conceptual model of social competence where the social brain's contributions to social behavior and functioning are mediated by social cognition, with an additional direct path between the brain and behavior. The relationship among the four components of social competence is not significantly different for autistic males and females. Social competence is best represented as a network of direct and indirect connections among the neural, cognitive, and behavioral components. Thus, focusing on any single element is not sufficient for effective design of novel assessment and treatment approaches in autism.

A total of 200 eyes were ultimately enrolled in this study, sourced from 53 individuals with ASD, aged between 7 and 13 years, and an equal number of age- and sex-matched neurotypical (NT) controls. The aim of this research is to explore the changes in retinal and choroidal vasculature in children with ASD, evaluated through optical coherence tomography and its angiography, and to further investigate the potential value of retinal vascular characteristics in the auxiliary screening and diagnosis of ASD. We analyzed intergroup differences in perfusion density (PD), vessel density, flux index (FI), fractal dimension (FD), and vessel diameter (Dm) in the peripapillary region, further stratified by subquadrants and vessel types. The results show that ASD children exhibited significant differences compared to neurotypical controls, including increased PD and Dm in the supero-nasal quadrant (p < 0.01), changes in capillary FI in the nasal quadrant (p = 0.008), increased venous FD (p = 0.009), and abnormal choroidal FI in the temporal quadrant (p = 0.008). A random forest classification model constructed based on these key features demonstrated promising performance (AUC = 0.7853) in distinguishing ASD from NT individuals, highlighting the potential of retinal vascular characteristics for auxiliary ASD screening. Moreover, retinal vascular parameters were significantly correlated (p < 0.01) with blood oxygen level-dependent signals from functional magnetic resonance imaging in several brain regions, such as the amygdala (p = 0.004-0.009) and temporal lobe (p = 0.000-0.009). Further stepwise regression analysis indicates that key retinal vascular characteristics could partially predict core clinical features of ASD, such as social functioning (adjusted R² = 0.091-0.104, quantified by total and subscale scores of Social Responsiveness Scale) and cognitive ability (adjusted R² = 0.2785, quantified by total intelligence quotient scores).

To address this gap, the current study took place in Ontario, Canada's largest province, where diverse populations and varied inclusive education policies create unique challenges. The study had two primary objectives: (1) to examine the relationship between parent satisfaction with the individual education plan (IEP) process and school exclusion, and (2) to identify key factors parents perceive as predictors of school exclusion in their autistic children. A total of 412 caregivers from Ontario completed an online survey, available in English and French, between April and July 2018. Quantitative analysis revealed that greater satisfaction with the IEP process was associated with a lower likelihood of school exclusion (b = -0.297, OR = 0.743, p < 0.001). Qualitative analysis of open-ended responses identified two primary contributors to exclusion: bullying by peers and inadequate training and support for school staff. These findings highlight the need for improved supports in educational settings, including comprehensive anti-bullying initiatives, stronger collaboration with parents in the development of IEPs, greater accountability in ensuring that IEPs are properly implemented, a more inclusive approach to meeting student needs, and increased funding for support staff. Addressing these areas could help reduce the risk of exclusion and foster a more equitable learning environment for autistic students.</p>","PeriodicalId":72339,"journal":{"name":"Autism research : official journal of the International Society for Autism Research","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144710025","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Gender incongruence involves a mismatch between one's experienced and assigned gender, often accompanied by significant distress (i.e., gender dysphoria). Recent studies revealed that autistic individuals report gender dysphoria more frequently than the general population and are overrepresented in gender clinic settings. Autistic individuals also report hypersensitivity to certain sensory stimuli, which can elicit distress. When this distress is triggered by certain auditory stimuli (e.g., one's or others' biological sounds such as chewing or swallowing) it is categorized as misophonia. Misophonia appears to be highly prevalent in autism. We propose that a lesser-studied phenomenon, puberphonia, could exemplify an attempt to reduce the distress elicited by misophonia in a certain category of individuals. Puberphonia is characterized by an unusually high-pitched voice, predominantly in teenage boys and men, that can occur in the absence of identifiable physical causes. The psychogenic aspects of puberphonia are just beginning to be explored. We hereby propose an exploratory direction, suggesting that puberphonia may be an individual's attempt at diminishing a distressing auditory stimulus (misophonia) due to their deepening voice. This, in turn, may be an indicator of unrecognized gender dysphoria. Given that voice pitch has also been reported to be higher in autistic males compared to controls, we further ask whether autism is more prevalent among cases of psychogenic puberphonia. Finally, we wish to draw attention to the need for research on the epidemiology and overlap of puberphonia, gender dysphoria, misophonia, and autism.</p>","PeriodicalId":72339,"journal":{"name":"Autism research : official journal of the International Society for Autism Research","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144710026","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we conducted polysomnography (PSG)/EEG recordings during afternoon naps on 50 children aged between 2 and 6 years, diagnosed with ASD or TD. EEG recordings from 19 scalp leads were analyzed, focusing on sigma power and sleep spindle parameters.

Additional frequency-specific analyses (10-12 Hz, 12-14 Hz, 14-16 Hz) confirmed significant differences in spindle amplitude and distribution patterns, emphasizing the role of brain regions that are detectable from anterior EEG leads in ASD-related sleep abnormalities. No significant differences were found in spindle density, duration, or frequency outside specific clusters. These findings indicate that some sleep spindle parameters, particularly in frontal areas, are altered in ASD.

Most studies involving children with ASD have focused on behavioral symptoms but not GISs. This systematic review and meta-analysis investigated the effects of gut microbiota-modulating interventions (GMMIs) on GISs and gut microbial composition in children with ASD. Five databases were searched for relevant domestic and international articles published from database inception until July 15, 2024. The meta-analysis included human trials wherein children with ASD received prebiotics, probiotics, synbiotics, or fecal microbiota transplantation. Intervention effects were measured on the basis of α-diversity, and genus- and phylum-level data were analyzed using a random-effects model and forest plots. This study included 19 trials (n = 1154). The results indicated that GMMIs significantly ameliorated GISs (p = 0.0017), reduced six-item Gastrointestinal Symptom Index scores by 1.86 points (p = 0.0187), and significantly increased the relative abundance of Bifidobacterium spp. (p = 0.0205). Longer interventions (≥ 8 weeks) were more effective in ameliorating GISs. Limitations in this investigation include the fact that the included studies neither incorporated any dietary control groups nor collected relevant dietary data, and the relatively small sample size (19 studies) may have hindered the identification of sources of heterogeneity in the pooled results. Overall, our findings suggest that GMMIs, especially probiotics, ameliorate GISs in children with ASD by modulating gut microbial composition, particularly by increasing the relative abundance of Bifidobacterium spp. These interventions may alleviate symptoms such as constipation, diarrhea, abnormal stool consistency and smell, flatulence, and abdominal pain.
