1. Akin-Bulbul I, Ozdemir S. Imitation Performance in Children with Autism and the Role of Visual Attention in Imitation. J Autism Dev Disord;2022 (Sep 9)

In this study, we examined imitation performance, visual attention, and the relationship between imitation and visual attention of children with autism, developmental delay (DD), and typically developing (TD) children. The study findings revealed that children with autism and DD imitated less than TD children in all imitation tasks. Results also showed that children with autism spent less time looking at the model’s face and movement area and more time looking at the external area. Lastly, the relationship between imitation and visual attention separated the study groups. The findings of the study provided new evidence that visual attention to movement area in children with autism was positively related to imitation performance in non-meaningful gestures.

2. Al Jaffal M. Barriers general education teachers face regarding the inclusion of students with autism. Front Psychol;2022;13:873248.

As the number of students diagnosed with autism spectrum disorder (ASD) present in general education (GE) classrooms has increased in the past few decades, GE teachers must adapt to meet the needs of these students. Laws and regulations require students with ASD to be educated in the least restrictive environment, as well as that they be instructed by the teachers who were qualified to teach them. Unfortunately, GE teachers face the challenges supporting students with ASD in GE settings. This qualitative research investigates the barriers that prevent teachers from successfully implementing an inclusive environment in the GE classroom. In total, four elementary school teachers at a school in the northeast of the United States were interviewed and observed. The data were analyzed to identify emerging themes. The findings showed that GE teachers lack training in how to work with students with ASD in their GE classrooms, lack collaboration opportunities with their special education colleagues to better support their students with ASD, and are not provided sufficient resources by their schools and programs to create an appropriate inclusive environment in their GE classrooms. Based on these findings, certain improvements in professional development offerings for in-service general educators on how to teach students with ASD are recommended, such as providing broader training programs that give teachers the opportunity to practice interventions and teaching plans for inclusive classrooms and receive feedback from the training instructor(s). Furthermore, certain additions to the curriculum of pre-service university education programs for GE teachers are suggested. In addition, the research found that schools must make certain resources, including technology, available to GE teachers to meet the requirements of United States law regarding educating students with disabilities, including ASD, in the least restrictive environment, which is the GE classroom.

3. Attar SM, Ibanez LV, Stone WL. Separate scoring algorithms for specific identification priorities optimize the screening properties of the Screening Tool for Autism in Toddlers (STAT). Autism Res;2022 (Sep 8)

The Screening Tool for Autism in Toddlers (STAT) is a validated stage-2 autism spectrum disorder (ASD) screening measure that takes 20 minutes to administer and comprises 12 play-based items that are scored according to specific criteria. This study examines an expanded version (STAT-E) that includes the examiner’s subjective ratings of children’s social engagement (SE) and atypical behaviors (AB) in the scoring algorithm. The sample comprised 238 children who were 24-35 months old. The STAT-E assessors had limited ASD experience to mimic its use by community-based non-specialists, and were trained using a scalable web-based platform. A diagnostic evaluation was completed by clinical experts who were blind to the STAT-E results. Logistic regression, ROC curves, and classification matrices and metrics were used to determine the screening properties of STAT-E when scored using the original STAT scoring algorithm versus a new algorithm that included the SE and AB ratings. Inclusion of the SE and AB ratings improved positive risk classification appreciably, while the specificity declined. These results suggest that the STAT-E using the original STAT scoring algorithm optimizes specificity, while the STAT-E scoring algorithm with the two new ratings optimizes the positive risk classification. Using multiple scoring algorithms on the STAT may provide improved screening accuracy for diverse contexts, and a scalable web-based tutorial may be a pathway for increasing the number of community providers who can administer the STAT and contribute toward increased rates of autism screening. LAY SUMMARY: Detecting autism in young children allows for timely access to specialized early intervention services. A new scoring system that incorporates two new ratings for the Screening Tool for Autism in Toddlers (STAT) significantly increased the number of children correctly identified at ASD risk when administered by novice STAT assessors who were trained using a web-based tutorial. Using web-based training and non-expert providers has the potential to increase the number of community providers who can administer the STAT and contribute toward increased rates of ASD screening and service access.

4. Bishop JC, Nichols C, Kranz S, Lukacs JK, Block ME. Determinants of physical activity of transitioning adult children with Autism Spectrum Disorder. Heliyon;2022 (Aug);8(8):e10150.

Many young adults on the autism spectrum do not attain the recommended minimum weekly amount of moderate to vigorous physical activity (MVPA) to prevent significant health risks. Autism symptoms as well as environmental factors may play a key role in the physical activity (PA) behaviors of young adults on the autism spectrum. The socioecological model (SEM) has been previously used to identify determinants of PA among people within many disability categories. AIMS: Explore the overall relationship between determinants of PA of MVPA among parents and their young adult child with ASD as well as MVPA determinants segmented by caregiver level of support. METHODS: 336 parents of adult children with ASD completed the Determinants of Physical Activity and Eating Behaviors for Young Adults with ASD Scale. RESULTS: Children’s weekly time spent in MVPA was predicted by parent self-reported MVPA, exercise competency, video game use, social skills, and neighborhood qualities. Parent weekly time spent in MVPA was predicted by their child’s weekly MVPA, parent exercise competency, parent discretionary time, available home exercise equipment, and parent attitude towards physical activity. CONCLUSION: These results support the administration of quality community-based motor development, motor skills, and exercise skills programs focused on increasing physical activity and parent’s influential role in their children’s weekly MVPA.

There is increasing evidence that diseases caused by dysfunctional mitochondria (MD) are associated with autism spectrum disorder (ASD). A comprehensive meta-analysis showed that developmental regression was reported in half of the children with ASD and mitochondrial dysfunction which is much higher than in the general population of ASD. The aim of the present exploratory study was to determine lactate concentrations in urine of children with ASD, as a non-invasive large-scale screening method for metabolic abnormalities including mitochondrial dysfunction and its possible association with regression. First, clinical characteristics of MD were examined in 99 children (3-11 years) with ASD. Second, clinical characteristics of MD, severity of ASD and reported regression were compared between children with the 20% lowest lactate concentrations and those with the 20% highest lactate concentrations in urine. Third, clinical characteristics of MD and lactate concentration in urine were compared in children with (n = 37) and without (n = 62) reported regression. An association of urine lactate concentrations with mitochondrial dysfunction and regression could not be demonstrated in our large ASD cohort. However, since ASD children were reported by their parents to show a broad range of phenotypic characteristics of MD (e.g., gastro-intestinal and respiratory impairments), and lactate concentrations in urine are not always increased in individuals with MD, the presence of milder mitochondrial dysfunction cannot be excluded. Development of alternative biomarkers and their implementation in prospective studies following developmental trajectories of infants at elevated likelihood for ASD will be needed in the future to further unravel the association of ASD with mitochondrial dysfunction and eventually improve early detection.

Development of a cost of illness inventory questionnaire for children with autism spectrum disorder in South Asia. BMC Health Serv Res;2022 (Sep 8);22(1):1137.

BACKGROUND: The economic burden of autism is substantial and includes a range of costs, including healthcare, education, productivity losses, informal care and respite care, among others. In India, approximately, 2 million children aged 2-9 years have autism. Given the likely substantial burden of illness and the need to identify effective and cost-effective interventions, this research aimed to produce a comprehensive cost of illness inventory (COII) suitable for children with autism in South Asia (India) to support future research. METHODS: A structured and iterative design process was followed to create the COII, including literature reviews, interviews with caregivers, pilot testing and translation. Across the development of the COII, thirty-two families were involved in the design and piloting of the tool. The COII was forward translated (from English to Hindi) and back translated. Each stage of the process of development of the COII resulted in the further refinement of the tool. RESULTS: Domains covered in the final COII include education, childcare, relocation, healthcare contacts (outpatient, inpatient, medical emergencies, investigations and medication), religious retreats and rituals, specialist equipment, workshops and training, special diet, support and care, certification, occupational adjustments and government rebates/schemes. Administration and completion of the COII determined it to be feasible to complete in 35 minutes by qualified and trained researchers. The final COII is hosted by REDCap Cloud and is a bilingual instrument (Hindi and English). CONCLUSIONS: The COII was developed using experiences gathered from an iterative process in a metropolitan area within the context of one low- and middle-income country (LMIC) setting, India. Compared to COII tools used for children with autism in high-income country settings, additional domains were required, such as complimentary medication (e.g. religious retreats and homeopathy). The COII will allow future research to quantify the cost of illness of autism in India from a broad perspective and will support relevant economic evaluations. Understanding the process of developing the questionnaire will help researchers working in LMICs needing to adapt the current COII or developing similar questionnaires.

The Integrated Therapy Model is a practice framework designed to promote multi-disciplinary collaboration to accommodate the holistic needs of children with special education needs. This study evaluated the effectiveness of the model adopted in a pilot preschool in China on children with autism spectrum disorder (ASD). A single-case, ABAB reversal design was employed with three children with ASD, and data were collected using direct observation and semi-structured interviews. The results demonstrated that while the model piloted in China was effective at improving fine motor ability, gross motor ability, imitation and problem behavior, it had mild to questionable effects on self-care and independent living capacity. The implications for the practice and for research on preschool interventions in mainland China is discussed.

8. Descloux V, Ruffieux N, Gasser AI, Maurer R. Severe developmental topographical disorientation associated with ADHD and dyscalculia: A case report. Neuropsychologia;2022 (Sep 9);174:108331.

We report the clinical case of AB, a right-handed 19-year-old woman who presents severe developmental topographical disorientation, a relatively rare syndrome, leading to difficulties in navigating in familiar (and novel) environments. This symptomatology appears without acquired cerebral damage (MRI described as normal) nor more global cognitive disability (high degree of education achieved). An extensive assessment of spatial cognition with different aspects of underlying cognitive processes is first presented. Second, the patient’s preserved cognitive abilities and her major difficulties in calculation, as well as her attention deficit, as seen in a detailed neuropsychological assessment, are reported. For the first time to our knowledge, we show that developmental topographical disorientation can be associated with other developmental cognitive disorders affecting number processing (dyscalculia) and attention (Attention Deficit-Hyperactivity Disorder (ADHD)). We discuss the links between these different cognitive processes in relation to visuo-spatial working memory and magnitude representation, which could represent common denominators for all these syndromes. This case report highlights the importance of thoroughly assessing potentially associated neurocognitive disorders in developmental topographical disorientation. In addition, it highlights the necessity to keep in mind the prevalence of spatial difficulties in the assessment of children and adolescents with other neurodevelopmental syndromes. Finally, this case study raises a new question about the nosology of developmental disorders affecting the visuo-spatial and spatial domains.

9. Gallant C, Roudbarani F, Ibrahim A, Maddox BB, Weiss JA. Clinician Knowledge, Confidence, and Treatment Practices in Their Provision of Psychotherapy to Autistic Youth and Youth with ADHD. J Autism Dev Disord;2022 (Sep 9)

Autistic youth have an increased risk of mental health problems. Despite the efficacy of various psychotherapeutic approaches for autistic youth, they often do not receive these interventions. Research is needed to identify patterns of effective treatment for autistic youth and whether they differ from those used for youth with other neurodevelopmental conditions (e.g., attention-deficit hyperactivity disorder; ADHD). We compared clinicians’ (N = 557) knowledge, confidence and practices when treating autistic youth and youth with ADHD. Although ratings were moderately high overall and similar interventions were used for both groups, clinicians were significantly less knowledgeable and confident when supporting autistic clients compared to clients with ADHD. Thus, improving clinician perspectives may help facilitate treatment for autistic youth with mental health problems.

Children and adolescents with ASD treated with CBD-rich cannabis exhibit significant improvements particularly in social symptoms: an open label study. Transl Psychiatry;2022 (Sep 9);12(1):375.

In recent years there has been growing interest in the potential benefits of CBD-rich cannabis treatment for children with ASD. Several open label studies and one double-blind placebo-controlled study have reported that CBD-rich cannabis is safe and potentially effective in reducing disruptive behaviors and improving social communication. However, previous studies have mostly based their conclusions on parental reports without the use of standardized clinical assessments. Here, we conducted an open label study to examine the efficacy of 6 months of CBD-rich cannabis treatment in children and adolescents with ASD. Longitudinal changes in social communication abilities and restricted and repetitive behaviors (RRB) were quantified using parent report with the Social Responsiveness Scale and clinical assessment with the Autism Diagnostic Observation Schedule (ADOS). We also quantified changes in adaptive behaviors using the Vineland, and cognitive abilities using an age-appropriate Wechsler test. Eighty-two of the 110 recruited participants completed the 6-month treatment protocol. While some participants did not exhibit any improvement in symptoms, there were overall significant improvements in social communication abilities as quantified by the ADOS, SRS, and Vineland with larger improvements in participants who had more severe initial symptoms. Significant improvements in RRB were noted only with parent-reported SRS scores and there were no significant changes in cognitive scores. These findings suggest that treatment with CBD-rich cannabis can yield improvements, particularly in social communication abilities, which were visible even when using standardized clinical assessments. Additional double-blind placebo-controlled studies utilizing standardized assessments are highly warranted for substantiating these findings.

12. Haghighi AH, Broughani S, Askari R, Shahrabadi H, Souza D, Gentil P. Combined Physical Training Strategies Improve Physical Fitness, Behavior, and Social Skills of Autistic Children. J Autism Dev Disord;2022 (Sep 9)

The present study aimed to investigate the effects of combined physical training (CPT) on social skills and physical fitness (PF) in children with ASD. Sixteen children with autism (age 6-10 years) were randomly assigned into two groups: CPT and control. The CPT group participated in a program involving ball game, rhythmic movements, and resistance training for eight weeks (three sessions per week). PF and behavior profile were assessed before and after training. CPT program had a significant effect on indicators of social skills such as stereotypic behavior and communication, as well as PF such as handgrip strength, upper and lower body power, flexibility, balance, and agility (P < 0.05). CPT in autistic children can improve indicators of social skills and PF.

13. Hunt E, Hogan A, Will EA, Roberts JE. ADHD and ASD symptoms in young males with fragile X syndrome: associations with early trajectories of inhibitory control. Child Neuropsychol;2022 (Sep 9):1-27.

Inhibitory control (IC), the ability to suppress inappropriate responses, emerges late in the first year of life and improves across typical development, concurrent with brain maturation. The development of IC is critical to various social-emotional and behavioral functions, with IC difficulties being linked to numerous neurodevelopmental disorders, including attention-deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (ASD). Fragile X syndrome (FXS) is a single-gene disorder characterized by IC difficulties, and elevated rates of ADHD and ASD, making it a useful model for understanding the early development and consequences of IC. In this longitudinal study, we characterized IC trajectories across multiple time points between 16 and 71 months of age in young males with FXS (n = 79) relative to neurotypical (NT) controls (n=49). To explore the association between behavioral outcomes and IC, we identified a subsample of 50 children with longitudinal IC data and an outcome assessment for ADHD and ASD symptoms at age 5 (FXS: n = 26, NT: n = 24). Results indicated that, compared to their NT peers, young males with FXS exhibit differences in IC as early as 24 months, with group differences increasing through age 5. Additionally, we determined that lower IC levels at 24 months were associated with later ADHD symptoms and a decreasing slope in IC over time was associated with later ASD symptoms in male children with FXS. These findings help refine early developmental phenotypes of FXS and highlight IC as a potential target for early detection and intervention of ASD and ADHD symptoms in male children with FXS.

AIM: The purpose of this study was to systematically review the neural similarities and differences in brain structure and function, measured by magnetic resonance imaging (MRI), in children with neurodevelopmental disorders that commonly co-occur to understand if and how they have shared neuronal characteristics. METHOD: Using systematic review methodology, the following databases were comprehensively searched: MEDLINE, EMBASE, CINAHL, CENTRAL, PsycINFO, and ProQuest from the earliest record up to December 2021. Inclusion criteria were: (1) peer-reviewed studies, case reports, or theses; (2) children under 18 years of age with at least one of the following neurodevelopmental disorders: autism spectrum disorder (ASD), attention hyperactivity deficit disorder (ADHD), developmental coordination disorder (DCD), and their co-occurrence; (3) studies based on MRI modalities (i.e., structural MRI, diffusion tensor imaging (DTI), and resting-state fMRI). Thirty-one studies that met the inclusion criteria were included for quality assessment by two independent reviewers using the Appraisal tool for Cross-Sectional Studies (AXIS). RESULTS: Studies compared brain structure and function of children with DCD and ADHD (n=6), DCD and ASD (n=1), ASD and ADHD (n=17), and various combinations of these co-occurring conditions (n=7). Structural neuroimaging (n=15) was the most commonly reported modality, followed by resting-state (n=8), DTI (n=5), and multi-modalities (n=3). INTERPRETATION: Evidence indicated that the neural correlates of the co-occurring conditions were more widespread and distinct compared to a single diagnosis. The majority of findings (77%) suggested that each neurodevelopmental disorder had more distinct neural correlates than shared neural features, suggesting that each disorder is distinct despite commonly co-occurring with each other. As the number of papers examining the co-occurrence of ASD, DCD, and/or ADHD was limited and most findings were not corrected for multiple comparisons, these results must be interpreted with caution.

BACKGROUND: There has been an increased emergence of the use of telerehabilitation by speech-language therapists (SLTs) in South Africa since the COVID-19 pandemic in 2020. OBJECTIVES: To explore the criteria that SLTs use when recommending telerehabilitation for children with autism spectrum disorder (ASD), the technical skills required, strategies used by SLTs, the restrictions encountered when conducting telerehabilitation and the views of SLTs on telerehabilitation in comparison to face-to-face therapy for children with ASD. METHOD: A descriptive, phenomenological, qualitative study design was utilised. Purposive and snowball sampling techniques were employed. Six SLTs from the private sector, who had experience providing telerehabilitation to children with ASD, were recruited from three provinces in South Africa. Data were gathered via semistructured online interviews and analysed using thematic analysis. RESULTS: Two out of five themes that emerged from this study are presented in this paper, i.e. approaches to telerehabilitation and the benefits of telerehabilitation. Results revealed that telerehabilitation was used to provide assessment and therapy during the COVID-19 pandemic lockdowns as an alternative method of service delivery. Assessment and treatment strategies included synchronous and asynchronous methods, family collaboration, social stories, frequent breaks and interactive sessions. Telerehabilitation reduced the client’s and SLT’s travel costs and increased caregiver and clinician satisfaction. Client progress and increased awareness of SLT were viewed as further benefits. CONCLUSION: Telerehabilitation was found to be beneficial to most children with ASD, and in most cases, the benefits far outweighed the challenges encountered. Clinical implications included the need for caregiver support in facilitating effective carryover, an increase in SLTs’ knowledge and the opportunity to provide services to a broader geographical range. Limitations of the study are included.

The formation of new phonological representations is key in establishing items in the mental lexicon. Phonological forms become stable with repetition, time and sleep. Atypicality in the establishment of new word forms is characteristic of children with developmental language disorder (DLD) and autism spectrum disorder (ASD), yet neural changes in response to novel word forms over time have not yet been directly compared in these groups. This study measured habituation of event-related-potentials (ERPs) to novel and known words within and between two sessions spaced 24 hours apart in typically developing (TD) children, and their peers with DLD or ASD. We hypothesised that modulation of the auditory N400 amplitude would mark real-time changes in lexical processing with habituation evident within and across sessions in the TD group, while the DLD group would show attenuated habituation within sessions, and the ASD group attenuated habituation between sessions. Twenty-one typically developing children, 19 children with ASD, and 16 children with DLD listened passively to known and novel words on two consecutive days, while ERPs were recorded using dry electrodes. Counter to our hypotheses, no habituation effect emerged within sessions. However, responses did habituate between sessions, with this effect being reduced in the DLD group, indicating less pre-activation of lexical representations in response to words encountered the previous day. No differences in change over time were observed between the TD and ASD groups. These data are in keeping with theories stressing the importance of sleep-related consolidation in word learning.

17. Lampinen LA, Zheng S, Taylor JL, Adams RE, Pezzimenti F, Asarnow LD, Bishop SL. Patterns of sleep disturbances and associations with depressive symptoms in autistic young adults. Autism Res;2022 (Sep 9)

Autistic individuals are at an increased risk for both sleep disturbances and depression. While studies in the general population and in autistic adults have drawn general links between sleep disturbances and mental health, few studies have examined the extent to which specific sleep problems may be implicated in the extremely high rates of depression among autistic adults. This study aimed to describe the patterns of sleep disturbances in autistic young adults, and their associations with depressive symptoms while controlling for relevant demographic factors. A sample of 304 legally independent adults (age 18-35 years old) with a childhood diagnosis of autism spectrum disorder self-reported on their average sleep behaviors during the past week and depressive symptoms on the Beck Depressive Inventory-II. A significant proportion (86.01%) of autistic young adults experienced at least one of the primary sleep disturbances of interest, including short total sleep time (39.59%), poor sleep efficiency (60.07%), and delayed sleep phase (36.18%). Additionally, lower sleep efficiency and delayed sleep phase were both associated with higher depressive symptoms. The associations between sleep and depressive symptoms identified in our study suggest that sleep treatments may hold potential for ameliorating depressive symptoms in autistic adults who also experience sleep problems. Further research using daily sleep diaries and objective measures of sleep behaviors, as well as longitudinal studies, are needed to understand how changes in sleep may relate to changes in depressive symptoms in autistic adults. LAY SUMMARY: Studies in the general population show that sleep disturbances may have a negative effect on mood. However, this relationship has not been sufficiently studied in autistic adults. More than 80% of autistic young adults in the study sample had sleep disturbances. Adults with certain sleep disturbances reported more depressive symptoms. Understanding the associations between sleep disturbances and depression in autistic adults may offer new avenues for mental health treatments in this population.

18. Li JC, Tsai SJ, Chen TJ, Chen MH. Sexually Transmitted Infection Among Adolescents and Young Adults with Autism Spectrum Disorder: A Nationwide Longitudinal Study. J Autism Dev Disord;2022 (Sep 8)

The association between autism spectrum disorder (ASD) and subsequent sexually transmitted infections (STIs) and the potential effects of medications on STI risk remain unknown. In all, 5076 adolescents and young adults with ASD and 57,060 age-/sex-matched individuals without ASD were enrolled between 2001 and 2009 and followed-up to the end of 2011 for identification of subsequent STIs. The results revealed that patients with ASD were prone to acquiring an STI [hazard ratio (HR) 3.36] compared with the comparison group. Long-term use of atypical antipsychotics was associated with a lower risk of acquiring an STI later in life compared with nonuse (HR 0.34). We recommend that clinicians closely monitor risky sexual behaviors and STI risk in patients with ASD.

PURPOSE: Although the challenges encountered by parents of children on the autism spectrum during the intervention process have garnered scholarly attention, how parents subjectively review those challenges and construct meanings of their experiences remained underexamined. By applying the narrative analysis framework, we investigated the lived experiences of parents of children on the autism spectrum regarding challenges they faced in the intervention process, along with the meanings of those experiences that they constructed in the sociocultural context of mainland China. METHODS: We purposively sampled 16 parents to narrate their experiences following semistructured interviews. Each participant had one child who had participated in autism intervention for more than two years. RESULT: The narrative analysis revealed that parents experienced a series of challenges imposed by structural barriers in the intervention process, which resulted in psychological distress and negative perceptions of their parental identities. Albeit susceptible to those adversities, the parents actively constructed new meanings of parenthood and their children’s situations through reflexive dialogues. CONCLUSION: Our results indicate the essential role of meaning-oriented coping in helping parents with children on the autism spectrum to mitigate the negative influence of challenges on their parental identity, strengthen their parent-child relationships, and readjust their priorities for intervention.IMPLICATIONS FOR REHABILITATIONThe role of encouraging new meanings through reflexive dialogues was found to be particularly important among parents with children on the autism spectrum to cope with the challenges they faced in the intervention process.New meanings assigned can mitigate the negative impact of challenges on parents’ parental identity, strengthening their parent-child relationships, and readjusting their priorities for intervention within the Chinese socio-cultural context.It is crucial for social workers and other practitioners to support parents in mainland China by facilitating them to assign new meanings to the challenging situations.It is important for social workers and other practitioners to encourage parents to cultivate inner strengths and self-value to support their children on the autism spectrum.

For most autistic children, spoken language emergence and development happen after the age of 3. Once they start developing and using spoken language, some eventually manage to reach typical levels of language abilities, while others remain minimally speaking into adulthood. It is therefore difficult to consider young autistic preschoolers as a homogeneous group in terms of spoken language levels. In our study, we breakdown a representative and inclusive group of children on the spectrum aged from 3 to 5 into five subgroups that correspond to different linguistic profiles. To do so, we qualitatively described children’s (pre)verbal productions elicited during interactions with a parent and with an experimenter. We then used a type of statistical analysis called cluster analysis to group together the children that had a similar expressive (pre)linguistic behavior. Using this analysis, we were able to delineate five linguistic profiles with qualitatively different patterns of vocal production. Two of these profiles are composed of speaking children; the three others are composed of non- or minimally speaking children. Our findings show that traditional binary division of speaking versus nonspeaking autistic children is not precise enough to describe the heterogeneity of early spoken language in young autistic children. They also support the use of qualitative descriptions of vocal productions and speech to accurately document children’s level of language, which could, in turn, help design very finely tailored language intervention specific to each child.

Autism is associated with inter-individual variations of gray and white matter morphology. Biol Psychiatry Cogn Neurosci Neuroimaging;2022 (Sep 5)

BACKGROUND: Although many studies have explored atypicalities in gray and white matter (GM, WM) morphology of autism, most of them rely on unimodal analyses that do not benefit from the likelihood that different imaging modalities may reflect common neurobiology. We aimed to establish brain patterns of modalities that differentiate between autism and controls and explore associations between these brain patterns and clinical measures. METHODS: We studied 183 individuals with autism and 157 non-autistic individuals (6-30 years) in a large deeply phenotyped autism dataset (EU-AIMS LEAP). Linked Independent Component Analysis was utilized to link all participants’ GM volume and WM diffusion tensor images, and group comparisons of modality shared variances were examined. Subsequently, we performed univariate and multivariate brain-behavior correlation analyses to separately explore the relations between brain patterns and clinical profiles. RESULTS: One multimodal pattern was significantly related to autism. This pattern was primarily associated with GM volume in bilateral insula, frontal, pre- and post-central, cingulate, and caudate areas, and co-occurred with altered WM features in the superior longitudinal fasciculus. The brain-behavior correlation analyses showed a significant multivariate association primarily between brain patterns that involved variation of WM, and symptoms of restricted and repetitive behavior in the autism group. CONCLUSIONS: Our findings demonstrate the assets of integrated analyses of GM and WM alterations to study the brain mechanisms that underpin autism, and show that the complex clinical autism phenotype can be interpreted by brain covariation patterns that are spread across the brain involving both cortical and subcortical areas.

22. Montenegro JTP, Seguin D, Duerden EG. Joint attention in infants at high familial risk for autism spectrum disorder and the association with thalamic and hippocampal macrostructure. Cereb Cortex Commun;2022;3(3):tgac029.

Autism spectrum disorder (ASD) is a heritable neurodevelopmental disorder. Infants diagnosed with ASD can show impairments in spontaneous gaze-following and will seldom engage in joint attention (JA). The ability to initiate JA (IJA) can be more significantly impaired than the ability to respond to JA (RJA). In a longitudinal study, 101 infants who had a familial risk for ASD were enrolled (62% males). Participants completed magnetic resonance imaging scans at 4 or 6 months of age. Subcortical volumes (thalamus, hippocampus, amygdala, basal ganglia, ventral diencephalon, and cerebellum) were automatically extracted. Early gaze and JA behaviors were assessed with standardized measures. The majority of infants were IJA nonresponders (n = 93, 92%), and over half were RJA nonresponders (n = 50, 52%). In the nonresponder groups, models testing the association of subcortical volumes with later ASD diagnosis accounted for age, sex, and cerebral volumes. In the nonresponder IJA group, using regression method, the left hippocampus (B = -0.009, aOR = 0.991, P = 0.025), the right thalamus (B = -0.016, aOR = 0.984, P = 0.026), as well as the left thalamus (B = 0.015, aOR = 1.015, P = 0.019), predicted later ASD diagnosis. Alterations in thalamic and hippocampal macrostructure in at-risk infants who do not engage in IJA may reflect an enhanced vulnerability and may be the key predictors of later ASD development.

Insistence on sameness is common in autistic individuals and continues into adulthood. Research shows it may be a way to cope with environments because of their sensory sensitivity, intolerance to uncertainty, and anxiety. Understanding the reasons for insistence on sameness from the perspective of autistic adults is important. To study the meanings of insistence on sameness for autistic adults, we interviewed 16 Brazilian autistic adults. All 10 formally diagnosed participants were diagnosed in adulthood. Six participants identified as being on the autism spectrum without formal diagnosis. During the interviews by email, we first asked about participants’ experiences with autism diagnosis, either formal diagnosis or self-diagnosis. Then, we asked about their experiences in places for eating out and grocery shopping. We found they tended to always go to the same places and use protective accessories to eat or shop comfortably. But their such behaviors were considered weird habits, first by other people and later by themselves. While trying to control their weird habits because of social pressure, they often suffered anxiety and meltdowns. When they finally learned of their autism in adulthood, they began to better understand who they are and why they experience the environment differently from others. This new understanding taught them that their so-called weird habits are actually part of their authentically autistic ways to cope with the weirder world. This study suggests that autistic adults’ insistence on sameness is an authentically autistic way to exercise their right to comfortably co-exist and live as human beings and as themselves.

24. Penton T, Bowling N, Vafeiadou A, Hammond C, Bird G, Banissy MJ. Attitudes to Interpersonal Touch in the Workplace in Autistic and non-Autistic Groups. J Autism Dev Disord;2022 (Sep 9)

Unemployment and underemployment have consistently been shown to be higher in autistic adults relative to non-autistic adults. This may be due, in part, to a lack of workplace accommodations being made for autistic people. One factor that may contribute to employment inequalities in autistic people is differences in attitudes towards interpersonal touch. This study acts as a preliminary investigation into whether employed autistic and non-autistic participants differ in their attitudes towards touch in the workplace, and in their loneliness and wellbeing. The current dataset was drawn from a larger online survey (the Touch Test) designed to explore attitudes and experiences towards touch. We found that employed autistic participants had more negative attitudes to general, social and workplace touch relative to non-autistic participants. Autistic participants also experienced greater loneliness and reduced wellbeing. Attachment-related anxiety was the only significant predictor of wellbeing in employed autistic adults. However, attachment-related anxiety, general attitudes to touch and the role of touch in the workplace predicted wellbeing in employed non-autistic adults. With regards to loneliness, general attitudes to touch and the role of touch in the workplace predicted loneliness in autistic participants. We also replicated the finding that a greater proportion of autistic participants were unemployed relative to non-autistic participants. Collectively, this research highlights the importance of considering touch in research investigating employment, and its impact on loneliness and wellbeing, in autistic participants.

PURPOSE: Literature supports the use of technological tools such as augmented reality, 3 D avatars and mobile devices to improve individuals with autism spectrum disorder skills. Possibilities of including these technological tools in intervention and the critical issues related to intervention design are essential research questions. The aim of the current work is to present an interdisciplinary research study on the design of an autism intervention considering these technologies. MATERIALS AND METHODS: This study used qualitative evidence and thematic analysis to identify the main design guidelines. A semi-structured interview was administered to a total of twenty participants representing four stakeholder categories: ASD, clinicians, therapists and caregivers. Interviews focussed on three dimensions related to user, technology and environment since they represent a complex system within which the individual using technology is situated. RESULTS: Thematic analysis of the interviews identified a total of 10 themes considered central to the design of the technological intervention. CONCLUSIONS: Since the application of technology in autism intervention is a relatively new area, the guidelines related to the potential incentives and barriers of the proposed technology are helpful to inform future treatment studies.Implications for RehabilitationThis study highlights the strengths and barriers associated with the use of smartphones and augmented reality in autism spectrum disorder interventions considering the dimensions within which the user using assistive technology is located.Strengths and major concerns that emerged are key points to consider during the development of the technological intervention.Considering these points can foster the use of technology within the intervention and promote its effectiveness.

Existing research has compared Family Quality of Life (FQOL) in autism spectrum disorder (ASD) populations and typically developing populations but has not yet explored differences in FQOL across ASD, attention-deficit/hyperactivity disorder (ADHD), and comorbid ASD and ADHD populations (ASD + ADHD). In the present study, 117 North American mothers of 92 sons and 25 daughters (ages 6-11) with ASD, ADHD, or ASD + ADHD completed an online survey exploring FQOL. An ANOVA failed to show group differences in overall FQOL, however, mothers of children with ASD + ADHD reported significantly lower family Emotional Well-being than mothers of children with ASD only. The results of this study provide insight into FQOL in families of children with ASD and/or ADHD. Greater research is needed in this area to understand how mothers of children with ASD, ADHD, or ASD + ADHD experience FQOL. The COVID-19 pandemic, which ran concurrent with this study, potentially influenced results.

Shurtz L, Schwartz C, DiStefano C, McPartland JC, Levin AR, Dawson G, Kleinhans NM, Faja S, Webb SJ, Shic F, Naples AJ, Seow H, Bernier RA, Chawarska K, Sugar CA, Dziura J, Senturk D, Santhosh M, Jeste SS. Concomitant medication use in children with autism spectrum disorder: Data from the Autism Biomarkers Consortium for Clinical Trials. Autism;2022 (Sep 9):13623613221121425.

Children with autism spectrum disorder are prescribed a variety of medications that affect the central nervous system (psychotropic medications) to address behavior and mood. In clinical trials, individuals taking concomitant psychotropic medications often are excluded to maintain homogeneity of the sample and prevent contamination of biomarkers or clinical endpoints. However, this choice may significantly diminish the clinical representativeness of the sample. In a recent multisite study designed to identify biomarkers and behavioral endpoints for clinical trials (the Autism Biomarkers Consortium for Clinical Trials), school-age children with autism spectrum disorder were enrolled without excluding for medications, thus providing a unique opportunity to examine characteristics of psychotropic medication use in a research cohort and to guide future decisions on medication-related inclusion criteria. The aims of the current analysis were (1) to quantify the frequency and type of psychotropic medications reported in school-age children enrolled in the ABC-CT and (2) to examine behavioral features of children with autism spectrum disorder based on medication classes. Of the 280 children with autism spectrum disorder in the cohort, 42.5% were taking psychotropic medications, with polypharmacy in half of these children. The most commonly reported psychotropic medications included melatonin, stimulants, selective serotonin reuptake inhibitors, alpha agonists, and antipsychotics. Descriptive analysis showed that children taking antipsychotics displayed a trend toward greater overall impairment. Our findings suggest that exclusion of children taking concomitant psychotropic medications in trials could limit the clinical representativeness of the study population, perhaps even excluding children who may most benefit from new treatment options.

28. Villegas-Lirola F. Prevalence of Autism Spectrum Disorder in Children in Andalusia (Spain). J Autism Dev Disord;2022 (Sep 8)

Autism Spectrum Disorder (ASD) is socially relevant because of its number and the intensity of the medical and socio-educational response it requires. In Andalusia, one in 70 children will be diagnosed with ASD in 2021. It is much more frequent in boys than in girls, being 5.91 times more likely to present it as a boy than as a girl. The age of diagnosis is increasingly younger, standing at 4.4 years. In more than half of primary schools and more than 75% of secondary schools there are an average of three students with ASD per school. It is necessary to develop a network of preferential care centers for students with ASD to generalize specialized care in ordinary modalities.

It has been known for a long time that individuals diagnosed with autism spectrum disorder perceive the world differently. In this study, we investigated how people with or without autism perceive visual and auditory information. We know that an auditory and a visual stimulus do not have to be perfectly synchronous for us to perceive them as synchronous: first, when the two are within a certain time window (temporal binding window), the brain will tell us that they are synchronous. Second, the brain can also adapt quickly to audiovisual asynchronies (rapid recalibration). Although previous studies have shown that people with autism spectrum disorder have different temporal binding windows, and less rapid recalibration, we did not find these differences in our study. However, we did find that both processes develop over age, and since previous studies tested only young people (children, adolescents, and young adults), and we tested adults from 18 to 55 years, this might explain the different findings. In the end, there might be quite a complex story, where people with and without autism spectrum disorder perceive the world differently, even dependent on how old they are.

Disrupted processing of social cues and altered social behaviors are among the core symptoms of autism spectrum disorders (ASDs), and they emerge as early as the first year of life. These differences in sensory abilities may affect the ability of children with ASDs to securely attach to a caregiver and experience caregiver buffering of stress. Prenatal exposure to valproic acid (VPA) has been used to model some aspects of ASDs in rodents. Here, we asked whether prenatal VPA exposure altered infant rats’ behavioral responsivity to maternal olfactory cues in an Odor Preference Test (OPT) and affected maternal buffering of infants’ stress responsivity to shock. In the odor preference test, 1-week old rats treated with VPA during pregnancy appeared to have impaired social recognition and/or may be less motivated to approach social odors in early infancy. These effects were particularly prominent in female pups. In 2-week old rats, VPA-exposed pups and saline-exposed pups showed similar preferences for home cage bedding. Although VPA-exposed pups may initially have a deficit in this attachment-related behavior they do recover typical responses to home cage bedding in later infancy. Both control and VPA-exposed pups showed robust stress hormone responses to repeated shocks, an effect which was blocked when a calm mother was present during shock exposure. No sex differences in the effect of maternal presence on the stress response to shock and no interactions between sex and prenatal drug exposure were observed. Although VPA-exposed pups may show impaired responsivity to maternal cues in early infancy, maternal presence is still capable of regulating the stress response in VPA-exposed pups. In this study we demonstrate the importance of utilizing multiple batteries of tests in assessing behavior, dissecting the behavior on one test into different components. Our results inform about the underlying behavioral characteristics of some of the ASD phenotypes, including sex differences reported by clinical studies, and could shed light on potential opportunities for intervention.

31. Zhang Y, Li D, Yang T, Chen C, Li H, Zhu C. Characteristics of emotional gaze on threatening faces in children with autism spectrum disorders. Front Psychiatry;2022;13:920821.

Most evidence suggested that individuals with autism spectrum disorder (ASD) experienced gaze avoidance when looking at the eyes compared to typically developing (TD) individuals. Children with ASD magnified their fears when received threatening stimuli, resulting in a reduced duration of eye contact. Few studies have explored the gaze characteristics of children with ASD by dividing emotional faces into threatening and non-threatening pairs. In addition, although dynamic videos are more helpful in understanding the gaze characteristics of children with ASD, the experimental stimuli for some of the previous studies were still emotional pictures. We explored the viewing of dynamic threatening and non-threatening faces by children with ASD in different areas of interest (AOIs). In this study, 6-10 years old children with and without ASD viewed faces with threatening (fearful and angry) and non-threatening (sad and happy) expressions, respectively, with their eyes movements recorded. The results showed that when confronted with threatening faces, children with ASD, rather than TD, showed substantial eye avoidances, particularly non-specific avoidances in the fixation time on the mouths and significantly less time gazing at the mouths in any emotions, which was not observed for non-threatening faces. No correlations were found between the severity of symptoms and characteristics of gaze at the eyes and mouths in children with ASD. These results further enhance the understanding of the gaze characteristics of children with ASD on threatening and non-threatening faces and possibly provide additional evidence for their social interaction improvements.
