It was recently argued that autism researchers committed to rejecting ableist frameworks in their research may sacrifice « scientifically accurate » conceptualizations of autism. In this perspective piece, we argue that: (a) anti-ableism vs. scientific accuracy is a false dichotomy, (b) there is no ideology-free science that has claim to scientific accuracy, and (c) autism science has a history of false leads in part because of unexamined ableist ideologies that undergird researcher framings and interpretations of evidence. To illustrate our claims, we discuss several avenues of autism research that were promoted as scientific advances, but were eventually debunked or shown to have much less explanatory value than initially proposed. These research programs have involved claims about autism etiology, the nature of autism and autistic characteristics, and autism intervention. Common to these false leads have been ableist assumptions about autism that inform researcher perspectives. Negative impacts of this work have been mitigated in some areas of autism research, but these perspectives continue to exert influence on the lives of autistic people, including the availability of services, discourses about autism, and sociocultural conceptualizations of autistic people. Examining these false leads may help current researchers better understand how ableism may negatively influence their areas of inquiry. We close with a positive argument that promoting anti-ableism can be done in tandem with increasing scientific accuracy.

PURPOSE: The aim of the present study was to explore the meaning of work for the subjective well-being of autistic adults with and without paid (competitive) employment and to evaluate the differences and similarities between these groups. METHODS: Eight focus groups were conducted, including a total of 64 autistic adults. Four groups entailed participants with current paid employment (including part-time) and four groups entailed participants without paid employment. All discussions were audiotaped and transcribed verbatim to enable inductive thematic content analysis. Data were analyzed using ATLAS.ti 9. RESULTS: Generally, both groups viewed paid employment as very important for well-being, albeit for different reasons. Three themes were found: (1) Not having paid employment was associated with lacking societal recognition, and subsequent low self-esteem, which was a dominant theme in those without work; (2) Work can seriously damage (mental) health and well-being, found in both groups; and (3) Paid employment provides many benefits for well-being, with subthemes: ‘purpose,’ ‘social contacts,’ ‘growth and use of talents,’ ‘structure and calmness,’ and ‘income and freedom’, which was a dominant theme in those with paid employment. CONCLUSIONS: Both groups found paid employment highly important for their well-being, albeit for different reasons. However, both also agreed that paid employment can be very harmful to (mental) health and well-being. Suitable, well-supported jobs are important for well-being, may help to buffer stress in other life areas, and may even prevent autistic burnout. More studies are needed on how healthy jobs can be created where autistic individuals get positive energy and experience high well-being. This will also help to reduce socio-economic inequality.

Although the electrophysiological event-related potential in face processing (e.g. N170) is widely accepted as a face-sensitivity biomarker that is deficient in children with autism spectrum disorders, the time-varying brain networks during face recognition are still awaiting further investigation. To explore the social deficits in autism spectrum disorder, especially the time-varying brain networks during face recognition, the current study analyzed the N170, cortical activity, and time-varying networks under 3 tasks (face-upright, face-inverted, and house-upright) in autism spectrum disorder and typically developing children. The results revealed a smaller N170 amplitude in autism spectrum disorder compared with typically developing, along with decreased cortical activity mainly in occipitotemporal areas. Concerning the time-varying networks, the atypically stronger information flow and brain network connections across frontal, parietal, and temporal regions in autism spectrum disorder were reported, which reveals greater effort was exerted by autism spectrum disorder to obtain comparable performance to the typically developing children, although the amplitude of N170 was still smaller than that of the typically developing children. Different brain activation states and interaction patterns of brain regions during face processing were discovered between autism spectrum disorder and typically developing. These findings shed light on the face-processing mechanisms in children with autism spectrum disorder and provide new insight for understanding the social dysfunction of autism spectrum disorder.

INTRODUCTION: While research shows no negative effects of bilingualism on autistic children’s development, due to misconceptions around both autism and bilingualism, bilingual parents and educational/clinical practitioners who advise them often express unfounded concerns that exposing autistic children to more than one language will cause confusion and developmental delays. To understand the reasons that drive these misconceptions, this study focuses on: identifying factors that impact family decisions about (not) raising autistic children bilingually; attitudes toward bilingualism expressed by the community, doctors, family members, and teachers; sources of information about bilingualism and autism available to families. METHODS: Through a mixed-method online survey, we explored these questions in 31 UK-based bilingual families with 34 autistic children (age M = 10.6 years; SD = 7.1). RESULTS: The families reported choosing bilingualism for their autistic child primarily so that the child can communicate with family and community members. Attitudes toward bilingualism in their networks were predominantly positive, with a large portion of individuals not having opinions possibly due to lack of information. Only about 1/3 of parents had access to information on bilingualism and autism, mostly found on the internet. DISCUSSION: We discuss these findings and offer future directions for research, practice, and battling stigmas around bilingualism and autism.

Effects of melatonin on dopaminergic neuron development via IP3-mediated mitochondrial Ca(2+) regulation in autism spectrum disorder. Biochemical and biophysical research communications. 2023; 681: 7-12.

Melatonin entrainment of suprachiasmatic nucleus-regulating circadian rhythms is mediated by MT1 and MT2 receptors. Melatonin also has neuroprotective and mitochondrial activating effects, suggesting it may affect neurodevelopment. We studied melatonin’s pharmacological effects on autism spectrum disorder (ASD) neuropathology. Deciduous tooth-derived stem cells from children with ASD were used to model neurodevelopmental defects and differentiated into dopaminergic neurons (ASD-DNs) with or without melatonin. Without melatonin, ASD-DNs had reduced neurite outgrowth, mitochondrial dysfunction, lower mitochondrial Ca(2+) levels, and Ca(2+) accumulation in the endoplasmic reticulum (ER) compared to control DNs from typically developing children-derived stem cells. Melatonin enhanced IP3-dependent Ca(2+) release from ER to mitochondria, improving mitochondrial function and neurite outgrowth in ASD-DNs. Luzindole, an MT1/MT2 antagonist, blocked these effects. Thus, melatonin supplementation may improve dopaminergic system development in ASD by modulating mitochondrial Ca(2+) homeostasis via MT1/MT2 receptors.

Children with autism are more likely to exhibit externalizing behaviors than children without autism. A cross-sectional study was undertaken to investigate how parental mental health status and parenting practices contributed to the variance in externalizing behaviors among families of young children with autism in Chinese mainland, and whether parenting behaviors had any indirect effects on the relationship between parental mental health symptoms and externalizing behaviors. Data were drawn from the baseline assessment of a quasi-experimental study of a parent training program delivered to Chinese caregivers of children with autism aged 3 to 6 from diverse backgrounds (N = 111). Results showed that parental mental health symptoms and parenting behaviors explained the variance in child externalizing behaviors. Parental mental health problems and parental over-reactivity were linked to higher levels of child externalizing behaviors, whereas positive parenting was associated with less frequent externalizing behaviors. Positive parenting partially explained the relationship between parental mental health symptoms and externalizing behaviors. The findings of this study highlight the importance of actively attending to the psychological and parenting needs of caregivers in autism treatment programs. It points to the need for the development of culturally sensitive strategies to promote parental mental health and increase the use of positive parenting skills among parents of children with autism.

Autism Caregiver Coaching in Africa (ACACIA): Protocol for a type 1-hybrid effectiveness-implementation trial. medRxiv : the preprint server for health sciences. 2023.

BACKGROUND: While early autism intervention can significantly improve outcomes, gaps in implementation exist globally. These gaps are clearest in Africa, where forty percent of the world’s children will live by 2050. Task-sharing early intervention to non-specialists is a key implementation strategy, given the lack of specialists in Africa. Naturalistic Developmental Behavioral Interventions (NDBI) are a class of early autism intervention that can be delivered by caregivers. As a foundational step to address the early autism intervention gap, we adapted a non-specialist delivered caregiver coaching NDBI for the South African context, and pre-piloted this cascaded task-sharing approach in an existing system of care. OBJECTIVES: First, we will test the effectiveness of the caregiver coaching NDBI compared to usual care. Second, we will describe coaching implementation factors within the Western Cape Department of Education in South Africa. METHODS: This is a type 1 effectiveness-implementation hybrid design; assessor-blinded, group randomized controlled trial. Participants include 150 autistic children (18-72 months) and their caregivers who live in Cape Town, South Africa, and those involved in intervention implementation. Early Childhood Development practitioners, employed by the Department of Education, will deliver 12, one hour, coaching sessions to the intervention group. The control group will receive usual care. Distal co-primary outcomes include the Communication Domain Standard Score (Vineland Adaptive Behavior Scales, Third Edition) and the Language and Communication Developmental Quotient (Griffiths Scales of Child Development, Third Edition). Proximal secondary outcome include caregiver strategies measured by the sum of five items from the Joint Engagement Rating Inventory. We will describe key implementation determinants. RESULTS: Participant enrolment started in April 2023. Estimated primary completion date is March 2027. CONCLUSION: The ACACIA trial will determine whether a cascaded task-sharing intervention delivered in an educational setting leads to meaningful improvements in communication abilities of autistic children, and identify implementation barriers and facilitators. TRIAL REGISTRATION: NCT05551728 in Clinical Trial Registry ( https://clinicaltrials.gov ).

9. Greenwood E, Cooklin A, Barbaro J, Miller C. Autistic patients’ experiences of the hospital setting: A scoping review. Journal of advanced nursing. 2023.

AIM: To explore the factors that affect the experiences of autistic patients in the hospital setting. DESIGN: A scoping review. DATA SOURCES: A systematic literature search using the databases CINAHL, Medline and Google Scholar was undertaken in September 2021 and updated in January 2023. This review is based on the methodological framework of Arksey and O’Malley (International Journal of Social Research Methodology, 8(1):19-32, 2005), which was further refined by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews. RESULTS: Autistic patients, as well as their families and healthcare staff, face several barriers that can impact their healthcare experiences within hospital settings. Of 211 articles screened, 30 were eligible and included. Through our review, we identified two main themes. The first theme, ‘challenges to hospital experiences’, includes four sub-themes: (1) communication, (2) a mismatch between the needs for autistic patients and the hospital environment, (3) challenges related to parents’ experiences and (4) challenges related to hospital systems. The second theme, ‘facilitators that improve hospital experiences’, includes three sub-themes: (1) provision of care pathways, (2) partnership between parents and experts and (3) facilitators to improve hospital systems. By understanding these themes, we can work to address the barriers that autistic patients and their families face, while leveraging the facilitators to improve their hospital experiences. CONCLUSION: It is critical to understand the experiences of autistic patients in the hospital setting because they present a substantial risk of hospital admission due to their associated acute to chronic health conditions. Additionally, nurses and other medical staff must understand the unique hospital experiences and challenges of autistic patients to improve care and facilitate better hospital experiences. This review further highlights the crucial need to adopt a collaborative and inclusive approach between autistic patients, their families and healthcare staff. To achieve this, co-design initiatives that incorporate the perspectives and lived experiences of the autistic community are necessary. By placing autistic voices at the forefront of these initiatives, it is hoped that changes are meaningful, relevant and can be sustained. IMPACT: Understanding the unique hospital experiences and challenges of autistic patients can improve their quality of life and well-being by reducing stress and anxiety during hospitalization, leading to better health outcomes and potentially shorter hospital stays. It can also promote a more positive view of healthcare among autistic individuals, encouraging them to seek medical care when needed and have broader societal impacts such as reducing healthcare costs and improving the overall health and well-being of the population. Autistic patients present a substantial risk of hospital admission due to their associated acute to chronic conditions. Nurses and other medical staff must understand the unique hospital experiences and challenges of autistic patients to improve care and facilitate better hospital experiences. PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution.

BACKGROUND: Autism is a lifelong condition that seriously affects many aspects of children’s and families’ lives. The experience attained by living with a child with autism can be a valuable source of information to provide support and satisfactory services to children with autism and their families. We aimed to investigate the lived experiences of Iranian parents of children with autism. METHODS: The search was conducted in PubMed, Web of Science, Embase, Google Scholar, CINAHL, PsychInfo, SID, and Magiran until Nov 2021. Two reviewers screened the articles, applied inclusion criteria, critically evaluated articles using the Critical Appraisal Skills Program (CASP), and extracted study details according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist. Thematic synthesis was used to analyze included studies. RESULTS: From 2772 articles in the initial search, sixteen studies entered the final analysis. Four themes emerged, including treatment-related lived experience, individual lived experience, social lived experience, and occupational lived experience. Iranian parents of children with autism are confronted with negative experiences, including inaccurate diagnostic processes, lack of adequate support at the diagnosis time, low-quality treatment, psychological problems, and concern about the child’s future. Also, Parent’s experiences showed family problems, stigma, and problems with doing occupations. CONCLUSION: Practitioners, policy-makers, and regulatory organizations should urgently consider issues mentioned in the parents’ experiences to provide proper healthcare services for children with autism and their families.

This systematic review evaluated the treatment effects of communication-focused parent-mediated interventions (CF-PMT), a form of intervention that involves therapists observing parent-child interactions and giving feedback to parents on how they can practice positive parenting strategies to prevent or reduce externalizing behaviours in children with developmental disabilities. A literature search was conducted on three electronic databases. To be included in the review, studies had to: evaluate CF-PMT where therapists give feedback after observing parent-child interactions; examine changes in externalizing behaviours amongst children with any forms of developmental disability; and adopt a randomised controlled trial study design. Fifteen studies met eligible criteria for the literature review, of those, 13 studies had available data on changes in the primary (child externalizing behaviours) and secondary outcomes (parental stress, child linguistic abilities and child social responsiveness). We found significant treatment effects for CF-PMT in reducing child externalizing behaviours (d = -.60) but not for any of the secondary outcomes. A sensitivity analysis showed a small but significant treatment effect for parental stress (d = -.18). Considerable bias was observed due to the lack of available information reported by studies on aspects measured by the Mixed Methods Appraisal Tool. Overall, we found evidence to support the benefits of complex interventions which incorporate direct parent-child observations and feedback to improve behavioural outcomes amongst children with developmental disabilities.

BACKGROUND: Resting state Functional Magnetic Resonance Imaging fMRI (rs-fMRI) has been used to study brain function in psychiatric disorders, yielding insight into brain organization. However, the high dimensionality of the rs-fMRI data presents challenges, and requires dimensionality reduction before applying machine learning techniques. Neural networks, specifically variational autoencoders (VAEs), have been instrumental in extracting low-dimensional latent representations of resting state functional connectivity patterns, addressing the complex nonlinear structure of rs-fMRI. However, interpreting those latent representations remains a challenge. This paper aims to address this gap by creating explainable VAE models and testing their utility using rs-fMRI data in autism spectrum disorder (ASD). METHODS: One-thousand one hundred and fifty participants (601 HC and 549 patients with ASD) were included in the analysis. We extracted functional connectivity correlation matrices from the preprocessed rs-fMRI data using Power atlas with 264 ROIs. Then VAEs were trained in an unsupervised fashion. Lastly, we introduce our latent contribution scores to explain the relationship between estimated representations and the original rs-fMRI brain measures. RESULTS: We quantified the latent contribution scores for the ASD and control groups at the network level. We found that both ASD and control groups share the top network connectivity that contribute to all estimated latent components. For example, latent 0 was driven by resting state functional connectivity patterns (rsFC) within ventral attention network in both the ASD and control. However, significant differences in the latent contribution scores between the ASD and control groups were discovered within the ventral attention network in latent 0 and the sensory/somatomotor network in latent 2. CONCLUSION: This study introduced latent contribution scores to interpret nonlinear patterns identified by VAEs. These scores effectively capture changes in each observed rsFC features as estimated latent representation changes, enabling an explainable deep learning model to better understand the underlying neural mechanism of ASD.

Association of adverse childhood experiences and cortical neurite density alterations with posttraumatic stress disorder symptoms in autism spectrum disorder. Frontiers in psychiatry. 2023; 14: 1215429.

BACKGROUND: Posttraumatic stress disorder (PTSD) can be a source of significant social and daily distress in autism spectrum disorder (ASD). Compared to typically developed (TD) individuals, people with ASD are at an increased risk of adverse childhood experiences (ACEs), which can result in abnormal neuronal development. However, whether or how ACEs influence abnormal neural development and PTSD symptoms in ASD has not been fully elucidated. METHODS: Thirty-nine TD individuals and 41 individuals with ASD underwent T1-weighted magnetic resonance imaging and neurite orientation dispersion and density imaging (NODDI), with axonal and dendritic densities assessed in terms of the orientation dispersion index and neurite density index (NDI), respectively. Voxel-based analyses were performed to explore the brain regions associated with PTSD symptoms, and the relationships between the severity of ACEs and PTSD symptoms and NODDI parameters in the extracted brain regions were examined. RESULTS: There was a significant positive association between PTSD symptom severity and NDI in the bilateral supplementary motor area; right superior frontal, left supramarginal, and right superior temporal gyrus; and right precuneus in the ASD group, but not in the TD group. ACE severity was significantly associated with NDI in the right superior frontal and left supramarginal gyrus and right precuneus in the ASD group. Moreover, NDI in the right precuneus mainly predicted the severity of PTSD symptoms in the ASD group, but not the TD group. CONCLUSION: These results suggest that ACE-associated higher neurite density is of clinical importance in the pathophysiology of PTSD symptoms in ASD.

PURPOSE: The majority of autistic toddlers present with clinically significant levels of internalizing or externalizing behaviors. Despite the prevalence of internalizing and externalizing behaviors in caseloads, the overwhelming majority of speech-language pathologists (SLPs) have not received specialized instruction in how to support children with these behaviors. The purpose of this study was to identify which child and caregiver characteristics are most associated with internalizing and externalizing behaviors in autistic toddlers in order to consider how SLPs may tailor their treatment to better support the individual needs of autistic children. METHOD: Participants included 109 mothers and their autistic children between 18 and 48 months of age. This study was a secondary analysis of data from a randomized clinical trial. Participants’ baseline data included a variety of child (i.e., expressive language, receptive language, restricted and repetitive behavior [RRB], and nonverbal cognition) and caregiver (i.e., self-efficacy and responsiveness) characteristics. Seemingly unrelated regressions were conducted to determine which characteristics were associated with internalizing and externalizing behaviors in autistic toddlers. RESULTS: Higher RRB scores were associated with both higher internalizing and externalizing behavior scores. A lower nonverbal cognition score was also associated with higher internalizing behavior scores but to a lesser extent than RRB. CONCLUSION: These findings suggest that SLPs may support internalizing and externalizing behaviors in autistic children by taking RRBs and nonverbal cognition into consideration.

The effect of background elements of pictures on the visual attention among ASD children with intellectual disabilities, children with intellectual disabilities and typical development: Evidence from eye-tracking and fMRI. Research in developmental disabilities. 2023; 141: 104602.

Traditional picture books for children come with colourful images and a multitude of elements to attract attention and increase the reading interest of typical-developing (TD) children. However, children with Autism Spectrum Disorder (ASD) are less capable of filtering out unimportant elements in pictures and focusing on social items (e.g., human faces). This study proposed that the removal of background and less important elements in the pictures of children’s storybooks could facilitate better attention and enhance children with ASD’s focus on the main object and thus the intended meaning of the storybook. We adopted pictures from a well-known children’s book and modified them by removing the inessential background elements. Then, ASD children with intellectual disabilities (ASD+ID) (n = 40), children with ID (n = 38) and TD (n = 40) were asked to view the original and modified pictures in an eye-tracking experiment, respectively. Additionally, brain activation of ASD+ID participants (n = 10) was recorded as they were viewing those pictures in an fMRI scan. Eye-tracking found that ASD+ID children viewed the modified pictures with significantly longer average fixations, fewer fixations, fewer saccades, and higher fixation/saccade duration ratio. Contrary to the original pictures, no significant differences were found among ASD+ID, ID only and TD. Especially, ASD+ID group showed highly similar visual patterns to the TD participants when viewing the modified pictures and particularly focusing on the main character in the pictures. Additional fMRI evidence on ASD+ID group also revealed that modified pictures were associated with enhanced activation in bilateral fusiform gyri as compared to those from original pictures, which might suggest increased visual attention. Theoretical and practical implications were discussed in light of our findings.

17. Liu M, Brady NC, Boorom O, Fleming K, Yue J, Liu Q. Prelinguistic communication complexity predicts expressive language in initial minimally verbal autistic children. International journal of language & communication disorders. 2023.

BACKGROUND: Prelinguistic communication complexity refers to the use of different communication forms such as eye gaze, gestures and vocalisations and the degree to which these forms are coordinated and how directed to a communication partner. To date, little is known about the relationship between prelinguistic communication complexity and expressive language in minimally verbal autistic children. AIMS: To test the hypothesis that prelinguistic communication complexity predicts expressive language 12 months later in autistic children and explore whether there are any differences in specific prelinguistic intentional communicative behaviours that are related to later expressive language levels. METHODS & PROCEDURES: This longitudinal study examined 37 minimally verbal autistic children (29-71 months old). The Communication Complexity Scale (CCS) was used to measure participants’ prelinguistic communication behaviours, which were extracted from a semi-structured play interaction at Time 1. The Chinese Communicative Development Inventory (CCDI) was used to examine participants’ expressive language at Time 1 and Time 2 (12 months later). According to Time 2 vocabulary size, participants were divided into two groups: Low CCDI, between 0 and 62 words, and High CCDI, more than 100 words. Linear regression was used to examine the relationship between early prelinguistic communication complexity and later expressive language. Binary logistic regression was used to determine which of the early communication behaviours were uniquely significantly related to later expressive language levels. OUTCOMES & RESULTS: There was a significant positive relationship between prelinguistic communication complexity and expressive language 12 months later, even after controlling for age and concurrent language. Findings revealed a group difference in the frequency of gesture and vocalisation combinations between the Low and High CCDI groups at Time 1. Gesture-vocalisation combinations also predicted better expressive language levels at Time 2. CONCLUSIONS & IMPLICATIONS: Our findings suggest that it may be beneficial to incorporate different complex communication behaviours into prelinguistic intervention targets for minimally verbal autistic children. The CCS hierarchies can be used as a reference for the intervention goals of minimally verbal autistic children. These findings highlight the importance of targeting gesture and vocalisation combinations when autistic children transition from single prelinguistic communication behaviours to multimodal behaviours. WHAT THIS PAPER ADDS: What is already known on this subject Children use eye gaze, gestures and vocalisations to communicate with others before they learn spoken language. There is strong evidence suggest that the frequency of prelinguistic communication predicts later linguistic achievements in autistic children. However, less is known about whether prelinguistic communication complexity also predicts later language and which specific behaviours are most predictive of language outcomes. What this study adds Minimally verbal autistic children who exhibit more complex prelinguistic communication behaviours have better expressive language 12 months later. Gestures combined with vocalisations predict better expressive language in minimally verbal autistic children. What are the clinical implications of this work? When identifying intervention targets for minimally verbal autistic children, the clinicians may reference the prelinguistic communication behaviours from the CCS. The gesture and vocalisation combinations are the key behaviours when targets transit from single form to two-form behaviours.

OBJECTIVE: Depression scores in caregivers of autistic children often fall in the clinical range. The attention of clinically depressed individuals tends to be biased toward negatively toned information. Whether caring for an autistic child might also be characterized by a negative attentional bias was explored here. METHODS: A sample of N = 98 (57 caregivers and 41 controls) completed questionnaires assessing depressive symptoms. Orienting attention to (i.e., vigilance), and shifting attention away from (i.e., disengagement), negative information was assessed via an online version of the emotional face dot probe task. RESULTS: Mean depression scores in caregivers, falling in the borderline clinical range, were significantly higher compared with controls. Groups, however, were indistinguishable with respect to vigilance and disengagement, and these attentional indices were unrelated to depression scores. CONCLUSION: Caring for an autistic child, while associated with borderline clinical depression scores, was not characterized by a negative attentional bias. Findings are discussed in the context of methodological shortcomings and recommendations for future research.

Individuals with autism spectrum disorder (ASD) exhibit a diverse range of behavioral features and genetic backgrounds, but whether different genetic forms of autism involve convergent pathophysiology of brain function is unknown. Here, we analyze evidence for convergent deficits in neural circuit function across multiple transgenic mouse models of ASD. We focus on sensory areas of neocortex, where circuit differences may underlie atypical sensory processing, a central feature of autism. Many distinct circuit-level theories for ASD have been proposed, including increased excitation-inhibition (E-I) ratio and hyperexcitability, hypofunction of parvalbumin (PV) interneuron circuits, impaired homeostatic plasticity, degraded sensory coding, and others. We review these theories and assess the degree of convergence across ASD mouse models for each. Behaviorally, our analysis reveals that innate sensory detection behavior is heightened and sensory discrimination behavior is impaired across many ASD models. Neurophysiologically, PV hypofunction and increased E-I ratio are prevalent but only rarely generate hyperexcitability and excess spiking. Instead, sensory tuning and other aspects of neural coding are commonly degraded and may explain impaired discrimination behavior. Two distinct phenotypic clusters with opposing neural circuit signatures are evident across mouse models. Such clustering could suggest physiological subtypes of autism, which may facilitate the development of tailored therapeutic approaches.

Independent and joint association of cord plasma pantothenate and cysteine levels with autism spectrum disorders and other neurodevelopmental disabilities in children born term and preterm. Precision nutrition. 2023; 2(2): e00036.

BACKGROUND: Pantothenate (vitamin B5) is a precursor for coenzyme A (CoA) synthesis, which serves as a cofactor for hundreds of metabolic reactions. Cysteine is an amino acid in the CoA synthesis pathway. To date, research on the combined role of early life pantothenate and cysteine levels in childhood neurodevelopmental disabilities is scarce. OBJECTIVE: To study the association between cord pantothenate and cysteine levels and risk of autism spectrum disorder (ASD), attention deficit hyperactivity disorder (ADHD) and other developmental disabilities (DD) in children born term and preterm. METHODS: The study sample (n = 996, 177 born preterm) derived from the Boston Birth Cohort included 416 neurotypical children, 87 ASD, 269 ADHD, and 224 other DD children, who were mutually exclusive. Participants were enrolled at birth and were followed up prospectively (from October 1, 1998, to June 30, 2018) at the Boston Medical Center. Cord blood sample was collected at birth. Plasma pantothenate and cysteine levels were measured using liquid chromatography-tandem mass spectrometry. RESULTS: Higher cord pantothenate (≥50th percentile vs. <50th percentile) was associated with a greater risk of ASD (adjusted odds ratio [aOR]: 1.94, 95% confidence interval [CI]: 1.06, 3.55) and ADHD (aOR: 1.66, 95% CI: 1.14, 2.40), after adjusting for potential confounders. However, cord cysteine alone was not associated with risk of ASD, ADHD, or other DD. When considering the joint association, greater ASD risk was noted when both cord pantothenate and cysteine levels were elevated (≥50th percentile) (aOR: 3.11, 95% CI: 1.24, 7.79), when compared to children with low cord pantothenate (<50th percentile) and high cysteine. Even though preterm and higher pantothenate independently increased the ASD risk, the greatest risk was found in preterm children who also had elevated pantothenate (≥50th percentile), which was true for all three outcomes: ASD (aOR: 5.36, 95% CI: 2.09, 13.75), ADHD (aOR: 3.31, 95% CI: 1.78, 6.16), and other DD (aOR: 3.39, 95% CI: 1.85, 6.24). CONCLUSIONS: In this prospective birth cohort, we showed that higher cord pantothenate individually and in combination with higher cysteine or preterm birth were associated with increased risk of ASD and ADHD. More study is needed to explore this biologically plausible pathway.

Autistic people have long been conceptualized from a deficit-based model of disability, but recent self-advocates and scholars have asserted the importance of recognizing autism as both a disability and an important part of a person’s social identity. The autistic identity is subject to specific stigma and stressors beyond everyday discrimination and prejudice, which can have many downstream implications on mental health and well-being. Prior research on camouflaging has explained both quantitatively and qualitatively how autistic people conform to norms and mask their autistic traits to better fit in with non-autistic societal standards. Given this paradigm shift in understanding autistic peoples’ lived experiences, researchers must also begin to reshape the theories guiding their work in order to improve diagnosis, intervention, and supports. This review examines the extant research on identity-related stigma and camouflaging and their subsequent impacts on mental health outcomes in autism. A model is proposed integrating identity-based theories-specifically the social model of disability, social identity theory, and minority stress model-to explain relationships across research areas and better explain the experiences of autistic people. We discuss how identity-based theories can be applied in autism research to better understand the impacts of stigma and camouflaging on autistic peoples’ lived experiences and reduce disparities in their mental health outcomes.

22. Rutten AX, Vermeiren R, Bongers IL, Van Nieuwenhuizen C. Likelihood of identifying autistic traits with the autism spectrum quotient (AQ) in male juveniles with autism spectrum disorder (ASD) and severe behavioral problems (SBPs). BMC psychiatry. 2023; 23(1): 694.

BACKGROUND: When screening for autism spectrum disorders (ASD), the Autism Spectrum Quotient (AQ) is generally considered to be useful. Whether the AQ is also a suitable screener for ASD in juveniles with severe behavioral problems (SBPs) is unknown. Due to the overlap of symptoms between ASD and SBPs, particularly in juveniles low on empathy, the screening capacity of the AQ might be constrained. The aim of the present study was to investigate whether (comorbid) SBPs affect the screening capacity of the AQ. The hypothesis is that male juveniles with SBPs – but without a diagnosis of ASD – will score higher than male juveniles without both SBPs and ASD. METHOD: The AQ was completed by 216 male juveniles aged 15-18 years treated at an outpatient department of child and adolescent psychiatry. The 216 participants were categorized into four groups according to a clinical diagnosis of ASD and SBPs (defined as disruptive behavior disorder and/or delinquent behavior). Using multinomial logistic regression, we investigated whether the four identified groups, based on a diagnosis of ASD and SBPs, scored differently for the total score and subscales of the AQ. RESULTS: Participants in the group with ASD (ASD(+)) but without SBPs (SBP(-)) were more likely to report higher levels of autistic traits than the reference group without both ASD and SBPs (ASD(-)SBP(-)), except for the subscale on attention to detail (ASD(+)SBP(-) OR = 1.04; 95%CI = 0.98-1.11). Participants in the group with both ASD and SBPs were more likely to report higher levels for the total AQ score (ASD(+)SBP(+) OR = 1.03; 95%CI = 1.00-1.05) and the communication subscale of the AQ (ASD(+)SBP(+) OR = 1.18; 95%CI = 1.07-1.31) than the reference group without both ASD and SBPs. CONCLUSION: In outpatient male juveniles, SBPs do not affect the screening capacity of the AQ for autistic traits. In spite of the well-known overlap of symptoms between ASD and SBPs, male juveniles with SBPs but without a diagnosis of ASD do not score higher on the AQ than male juveniles without SBPs and without a diagnosis of ASD.

Autism spectrum disorder (ASD) is a neurodevelopmental condition characterized by pervasive deficits in social interaction, communication impairments, and the presence of restricted and repetitive behaviors. This complex disorder is a significant public health concern due to its escalating incidence and detrimental impact on quality of life. Currently, extensive investigations are underway to identify prospective susceptibility or predictive biomarkers, employing a physiological biomarker-based framework. However, knowledge regarding physiological biomarkers in relation to Autism is sparse. We performed a scoping review to explore putative changes in physiological activities associated with behaviors in individuals with Autism. We identified studies published between January 2000 and June 2023 from online databases, and searched keywords included electroencephalography (EEG), magnetoencephalography (MEG), electrodermal activity markers (EDA), eye-tracking markers. We specifically detected social-related symptoms such as impaired social communication in ASD patients. Our results indicated that the EEG/ERP N170 signal has undergone the most rigorous testing as a potential biomarker, showing promise in identifying subgroups within ASD and displaying potential as an indicator of treatment response. By gathering current data from various physiological biomarkers, we can obtain a comprehensive understanding of the physiological profiles of individuals with ASD, offering potential for subgrouping and targeted intervention strategies.

The Selective Social Attention task in children with autism spectrum disorder: Results from the Autism Biomarkers Consortium for Clinical Trials (ABC-CT) feasibility study. Autism research : official journal of the International Society for Autism Research. 2023.

The Selective Social Attention (SSA) task is a brief eye-tracking task involving experimental conditions varying along socio-communicative axes. Traditionally the SSA has been used to probe socially-specific attentional patterns in infants and toddlers who develop autism spectrum disorder (ASD). This current work extends these findings to preschool and school-age children. Children 4- to 12-years-old with ASD (N = 23) and a typically-developing comparison group (TD; N = 25) completed the SSA task as well as standardized clinical assessments. Linear mixed models examined group and condition effects on two outcome variables: percent of time spent looking at the scene relative to scene presentation time (%Valid), and percent of time looking at the face relative to time spent looking at the scene (%Face). Age and IQ were included as covariates. Outcome variables’ relationships to clinical data were assessed via correlation analysis. The ASD group, compared to the TD group, looked less at the scene and focused less on the actress’ face during the most socially-engaging experimental conditions. Additionally, within the ASD group, %Face negatively correlated with SRS total T-scores with a particularly strong negative correlation with the Autistic Mannerism subscale T-score. These results highlight the extensibility of the SSA to older children with ASD, including replication of between-group differences previously seen in infants and toddlers, as well as its ability to capture meaningful clinical variation within the autism spectrum across a wide developmental span inclusive of preschool and school-aged children. The properties suggest that the SSA may have broad potential as a biomarker for ASD.

INTRODUCTION: Self-determination is a fundamental human right positively related to quality of life. However, Autistic people are reported to be less self-determined than non-autistic people. We aimed to (1) understand what self-determination means to Autistic people from their perspective, (2) explore their perceptions of current barriers to being self-determined, and (3) learn from Autistic people about how they would like to be supported to be self-determined. METHODS: Semi-structured interviews were done with 19 Autistic adults without co-occurring intellectual disability. Data were analyzed by three Autistic and two non-autistic researchers through an iterative process of data familiarization, coding, and theme development, informed by reflexive thematic analysis. Autistic Community Partners (ACP) were also engaged throughout the study, and provided substantive feedback on all methods and results. RESULTS: Self-determination held the same meaning for Autistic people as non-autistic people. More specifically, participants discussed having the opportunity and support to make choices and decisions in life without unnecessary control from others. Experiences of self-determination were centered around: (1) lack of opportunity, influenced by ableist expectations and discrimination, and (2) executive processing differences that interfered with choice and decision-making. Desired areas of support related to providing opportunities to (1) make choices and exert autonomy, (2) be supported to unmask and be valued as one’s authentic Autistic self, and (3) offering pragmatic support for executive processing differences. CONCLUSION: Autistic adults desire to be self-determined and can flourish with support, as they determine to be appropriate, which might look different from support commonly offered or sought by non-autistic people. Although individualized support was discussed, the ideal desired support was for an inclusive society that values and respects their neurodivergence, rather than imposing ableist expectations. An inclusive society is only achievable through reduced (or eliminated) stigma and prejudice against Autistic people.
