OBJECTIVE: To study atypical eating behavior (AEB) in various variants of autism spectrum disorder (ASD) to determine the prognosis and therapeutic tactics. MATERIAL AND METHODS: One hundred and eighty patients (110 girls, 70 boys), aged 2 to 5 years (mean age 4 years), with a diagnosis of «Childhood autism» (F84.02), «Atypical autism» (F84.1), «Asperger Syndrome» (F84.5) and the presence of AEB were examined. RESULTS: Three clinical variants of ASD accompanied by AEB were identified: catatonic-regressive (n=75, 41%), catatonic (n=81, 45%) and hyperdynamic (n=24, 13%). The most pronounced AEB were in the catatonic-regressive variant, and the least in the hyperdynamic variant of ASD. The severity of AEB is associated with the severity of cognitive dysontogenesis. CONCLUSION: The characteristics of AEB are associated with the leading clinical syndrome of ASD. The severity of catatonia and regression affects the depth of AEB, which leads to secondary somatic disorders. Specialists of various profiles should participate in medical work for successful rehabilitation and prevention of somatic complications.

2. Brignell A, Harwood RC, May T, Woolfenden S, Montgomery A, Iorio A, Williams K. Overall prognosis of preschool autism spectrum disorder diagnoses. Cochrane Database Syst Rev;2022 (Sep 28);9(9):CD012749.

BACKGROUND: Autism spectrum disorder is a neurodevelopmental disorder characterised by social communication difficulties, restricted interests and repetitive behaviours. The clinical pathway for children with a diagnosis of autism spectrum disorder is varied, and current research suggests some children may not continue to meet diagnostic criteria over time. OBJECTIVES: The primary objective of this review was to synthesise the available evidence on the proportion of preschool children who have a diagnosis of autism spectrum disorder at baseline (diagnosed before six years of age) who continue to meet diagnostic criteria at follow-up one or more years later (up to 19 years of age). SEARCH METHODS: We searched MEDLINE, Embase, PsycINFO, and eight other databases in October 2017 and ran top-up searches up to July 2021. We also searched reference lists of relevant systematic reviews. SELECTION CRITERIA: Two review authors independently assessed prospective and retrospective follow-up studies that used the same measure and process within studies to diagnose autism spectrum disorder at baseline and follow-up. Studies were required to have at least one year of follow-up and contain at least 10 participants. Participants were all aged less than six years at baseline assessment and followed up before 19 years of age. DATA COLLECTION AND ANALYSIS: We extracted data on study characteristics and the proportion of children diagnosed with autism spectrum disorder at baseline and follow-up. We also collected information on change in scores on measures that assess the dimensions of autism spectrum disorder (i.e. social communication and restricted interests and repetitive behaviours). Two review authors independently extracted data on study characteristics and assessed risk of bias using a modified quality in prognosis studies (QUIPS) tool. We conducted a random-effects meta-analysis or narrative synthesis, depending on the type of data available. We also conducted prognostic factor analyses to explore factors that may predict diagnostic outcome. MAIN RESULTS: In total, 49 studies met our inclusion criteria and 42 of these (11,740 participants) had data that could be extracted. Of the 42 studies, 25 (60%) were conducted in North America, 13 (31%) were conducted in Europe and the UK, and four (10%) in Asia. Most (52%) studies were published before 2014. The mean age of the participants was 3.19 years (range 1.13 to 5.0 years) at baseline and 6.12 years (range 3.0 to 12.14 years) at follow-up. The mean length of follow-up was 2.86 years (range 1.0 to 12.41 years). The majority of the children were boys (81%), and just over half (60%) of the studies primarily included participants with intellectual disability (intelligence quotient < 70). The mean sample size was 272 (range 10 to 8564). Sixty-nine per cent of studies used one diagnostic assessment tool, 24% used two tools and 7% used three or more tools. Diagnosis was decided by a multidisciplinary team in 41% of studies. No data were available for the outcomes of social communication and restricted and repetitive behaviours and interests. Of the 42 studies with available data, we were able to synthesise data from 34 studies (69% of all included studies; n = 11,129) in a meta-analysis. In summary, 92% (95% confidence interval 89% to 95%) of participants continued to meet diagnostic criteria for autism spectrum disorder from baseline to follow-up one or more years later; however, the quality of the evidence was judged as low due to study limitations and inconsistency. The majority of the included studies (95%) were rated at high risk of bias. We were unable to explore the outcomes of change in social communication and restricted and repetitive behaviour and interests between baseline and follow-up as none of the included studies provided separate domain scores at baseline and follow-up. Details on conflict of interest were reported in 24 studies. Funding support was reported by 30 studies, 12 studies omitted details on funding sources and two studies reported no funding support. Declared funding sources were categorised as government, university or non-government organisation or charity groups. We considered it unlikely funding sources would have significantly influenced the outcomes, given the nature of prognosis studies. AUTHORS' CONCLUSIONS: Overall, we found that nine out of 10 children who were diagnosed with autism spectrum disorder before six years of age continued to meet diagnostic criteria for autism spectrum disorder a year or more later, however the evidence was uncertain. Confidence in the evidence was rated low using GRADE, due to heterogeneity and risk of bias, and there were few studies that included children diagnosed using a current classification system, such as the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) or the eleventh revision of the International Classification of Diseases (ICD-11). Future studies that are well-designed, prospective and specifically assess prognosis of autism spectrum disorder diagnoses are needed. These studies should also include contemporary diagnostic assessment methods across a broad range of participants and investigate a range of relevant prognostic factors.

[Paired and partial correlations of immune parameters of neuro-immuno-test and coagulation parameters of thrombodynamics test in children with children’s autism]. Zh Nevrol Psikhiatr Im S S Korsakova;2022;122(9. Vyp. 2):68-73.

OBJECTIVE: To reveal paired and partial correlations of values of neuro-immuno-test and thrombodynamics test in children with childhood autism and schizophrenia in childhood in a state of exacerbation. MATERIAL AND METHODS: The study used a database of children with childhood autism, obtained by us in 2028-2019. The study included 46 patients with childhood autism (CA) aged 2 to 13 years: median age [Q1; Q3] – 5 years [4; 7], 10 girls (22%) and 36 boys (78%)). The thrombodynamics test (TD) was performed on a T-2 thrombodynamics analyzer according to the manufacturer’s instructions. RESULTS: It was shown that there is a statistically significant positive correlation (R=0.369, p=0.018) between the acquired immunity parameter: the level of serum antibodies to myelin basic protein (BMP): abBMP parameter, and the main parameter of platelet hemostasis – the time of appearance of spontaneous clots (Tsp). It can be assumed that autoantibodies to BMP block the procoagulant effect of myelin basic protein and thus have an anticoagulant effect. However, this analysis did not take into account the possible effects of other parameter of the neuro-immuno-test and thrombodynamics test. Therefore, when studying the correlation of specific parameters of the neuro-immuno-test and thrombodynamics, it is necessary to take into account the possible modifying effect of other parameters of these tests. It was shown that after subtracting the influence on the main correlation (abBMP & Tsp) of individual thrombodynamic parameters (Vi, V and D), as well as their total influence, the partial correlations become statistically insignificant. This indicates that these TD parameters can, individually or in total, determine the revealed correlation between the levels of antibodies to the basic myelin protein (Basic Myelin Protein) and the time of the appearance of spontaneous clots. CONCLUSION: Thus, it was shown that the correlations between the studied parameters of the neuro-immuno-test and the indicators of the thrombodynamics test mutually depend on the other indicators of these tests. This confirms the hypothesis that the immune system and the hemostatic system are two different sides of a single supersystem.

Health Care Bias and Discrimination Experienced by Lesbian, Gay, Bisexual, Transgender, and Queer Parents of Children With Developmental Disabilities: A Qualitative Inquiry in the United States. J Pediatr Health Care;2022 (Sep 29)

INTRODUCTION: This study explored the impact of health care (HC) bias and discrimination on lesbian, gay, bisexual, transgender, and queer (LGBTQ) parents and their children with disabilities in the United States, including the timing of developmental screening and diagnosis. METHOD: We conducted semistructured interviews with 16 LGBTQ parents of children with developmental concerns or disabilities recruited through a prior national survey. Interviews were transcribed and analyzed using a combined inductive and deductive approach. RESULTS: Discrimination types reported included noninclusive forms, disclosure challenges, and providers dismissing nongestational parents and diverse families. Few parents reported screening and diagnosis delays. Parents’ recommendations included: avoiding assumptions, honoring family diversity, increasing LGBTQ family support, improving HC forms, increasing antibias training, and convening a learning community. DISCUSSION: Our study advances the knowledge around HC bias and discrimination among LGBTQ parents of children with disabilities. Findings highlight the need for increased LGBTQ-affirming family support and research representing LGBTQ family diversity in U.S. health care.

INTRODUCTION: Neurodevelopmental disorders have a multifactorial etiology that results from the interaction between biological and environmental factors. The biological basis of many of these disorders is only partially understood, which makes therapeutic interventions, especially pharmacological ones, particularly difficult. The impact of medical cannabis on neurological and psychiatric disorders has been studied for a long time. This study aimed to review the currently available clinical and pre-clinical studies regarding the use of cannabinoids in pediatric neurodevelopmental disorders and to draw attention to the potential therapeutic role of cannabidiol in this field. DEVELOPMENT: Cannabidiol is an endocannabinoid system modulator and exerts its effects on both developing and mature brains through numerous mechanisms. Cannabidiol holds a relatively high toxicity limit and current literature suggests that it may have anxiolytic, antipsychotic, and neuroprotective properties. Clinical evidence suggests that early treatment with cannabidiol might be a promising therapy for neurodevelopmental disorders, including intellectual disability, autism spectrum disorders, tics, and attention/deficit hyperactivity disorder. CONCLUSIONS: This review hopefully draws attention to an emerging body of evidence concerning cannabidiol’s significant potential to safely improve many of the common symptoms affecting children and adolescents with neurodevelopmental disorders, especially autism spectrum disorder.

OBJECTIVE: Fragile X premutation carriers are reported to have increased neuropsychiatric problems, and thus the term fragile X-associated neuropsychiatric disorders (FXAND) has been proposed. Unfortunately, published prevalence estimates of these phenomena are inconsistent. This systematic review clarified this issue by reviewing both fragile X premutation prevalence in patients with neurodevelopmental disorders and psychiatric disorder prevalence in premutation carriers without fragile X-associated tremor/ataxia syndrome (FXTAS). Average prevalence was derived from studies that used semistructured clinical interviews, diagnostic criteria, and validated rating scales. METHODS: Forty-six studies were reviewed. The rate of fragile X premutation in neurodevelopmental disorders was assessed from five studies. Probands with neurodevelopmental disorders were more likely than those in the general population to be premutation carriers. The rate of psychiatric disorders in premutation carriers was assessed from five studies for neurodevelopmental, 13 studies for mood, 12 studies for anxiety, and two studies for psychotic disorders. The phenotype and sex distribution among premutation carriers were similar to those with fragile X syndrome. RESULTS: Compared to control group and general population estimates, the most prevalent psychiatric disorders were neurodevelopmental disorders, anxiety disorders, and bipolar II disorder. Psychiatric disorders were also more common in males. Most studies relied only on past medical history to define the prevalence of psychiatric disorders, yielding variability in results. CONCLUSIONS: Future studies are needed to avoid bias by identifying cohorts from population-based sampling, to describe cohort demographic characteristics to elucidate differences in age and sex, and to prioritize the use of validated psychiatric assessment methods.

Autism traits are common exclusionary criteria in developmental prosopagnosia (DP) studies. We investigated whether autism traits produce qualitatively different face processing in 43 DPs with high vs. low autism quotient (AQ) scores. Compared to controls (n = 27), face memory and perception were similarly deficient in the high- and low-AQ DPs, with the high-AQ DP group additionally showing deficient face emotion recognition. Task-based fMRI revealed reduced occipito-temporal face selectivity in both groups, with high-AQ DPs additionally demonstrating decreased posterior superior temporal sulcus selectivity. Resting-state fMRI showed similar reduced face-selective network connectivity in both DP groups compared with controls. Together, this demonstrates that high- and low-AQ DP groups have very similar face processing deficits, with additional facial emotion deficits in high-AQ DPs.

The efficacy of the Australian Disability Employment Services (DES) for autistic jobseekers has not been examined and is currently undergoing Government reform. To help inform the new DES strategy, we sought the views of: 24 autistic individuals; seven family members of autistic individuals, and; 46 DES employees. Data were collected using surveys and interviews. Data were analysed using Mann Whitney tests plus deductive thematic analysis based on Nicholas and colleagues’ ecosystems model. Participants highlighted a need to adapt existing policies to enhance flexibility of the DES model. There was participant consensus that DES staff require specific education and training to meet the needs of autistic people. Suggestions to inform the new model of DES for autistic people are made.

Comparison of the Social Responsiveness Scale-2 among Individuals with Autism Spectrum Disorder and Williams Syndrome in Japan. J Autism Dev Disord;2022 (Sep 27)

This study examined the similarities/differences between the social phenotypes of Williams syndrome (WS) and autism spectrum disorder (ASD). As cultural norms may affect symptom evaluation, this study administered the Social Responsiveness Scale-2 to Japanese individuals with WS (n = 78, 4.4-44.0 years) and ASD (n = 75, 4.7-55.4 years). The scores for Social Motivation and Social Communication were significantly more severe in the ASD than WS group. Overall, the similarities and differences between the social phenotypes of the syndromes were consistent with the findings of a recent study conducted in the UK, except for the social awareness subscale score. This highlights the importance of cross-cultural investigations of WS and ASD.

A microdeletion of approximately 2.4 Mb at the 8p23 terminal region has been identified in a Taiwanese autistic boy. Among the products transcribed/translated from genes mapped in this region, the reduction of DLGAP2, a postsynaptic scaffold protein, might be involved in the pathogenesis of autism spectrum disorder (ASD). DLGAP2 protein was detected in the hippocampus yet abolished in homozygous Dlgap2 knockout (Dlgap2 KO) mice. In this study, we characterized the hippocampal phenotypes in Dlgap2 mutant mice. Dlgap2 KO mice exhibited impaired spatial memory, indicating poor hippocampal function in the absence of DLGAP2. Aberrant expressions of postsynaptic proteins, including PSD95, SHANK3, HOMER1, GluN2A, GluR2, mGluR1, mGluR5, βCAMKII, ERK1/2, ARC, BDNF, were noticed in Dlgap2 mutant mice. Further, the spine density was increased in Dlgap2 KO mice, while the ratio of mushroom-type spines was decreased. We also observed a thinner postsynaptic density thickness in Dlgap2 KO mice at the ultrastructural level. These structural changes found in the hippocampus of Dlgap2 KO mice might be linked to impaired hippocampus-related cognitive functions such as spatial memory. Mice with Dlgap2 deficiency, showing signs of intellectual disability, a common co-occurring condition in patients with ASD, could be a promising animal model which may advance our understanding of ASD.

12. Jameson C, Boulton KA, Silove N, Guastella AJ. Eczema and related atopic diseases are associated with increased symptom severity in children with autism spectrum disorder. Transl Psychiatry;2022 (Sep 28);12(1):415.

Growing evidence indicates that autism spectrum disorder (ASD) has diverse genetic, neurological, and environmental factors that contribute to its neurodevelopmental course. Interestingly, childhood ASD is often accompanied by skin disorders, such as eczema, and other related atopic manifestations. This link may be due to the shared embryonic origin of epidermal and neural tissue. Accordingly, we consider the potential influence of a skin-brain co-vulnerability and ensuing atopic cascade on ASD symptomatology by investigating whether atopic disorders (asthma, allergies, eczema and hay fever) are associated with increased symptom severity in children with ASD. Overall, 45 atopic and 93 non-atopic children with ASD were assessed using the ADOS-2 on scores of total, social and non-social symptoms. Differences in ASD symptom severity were further evaluated as a function of atopic disease type. Atopic children displayed greater symptom severity overall and in the social domain, relative to non-atopic participants. Atopic children were 2.4 times more likely to experience overall impairments classified within the ADOS-2 highest-level severity bracket and 2.7 times more likely to show social difficulties in this range. Moreover, those reporting comorbid eczema displayed increased symptom severity relative to both their non-atopic peers and those reporting asthma and allergies. Taken together, findings indicate that atopic disorders, and particularly comorbid eczema, are associated with increases in ASD symptom severity. Findings provide grounds for future investigations into this link between childhood skin diseases and ASD symptom severity to advance our understanding of neurodevelopment and to develop targeted assessment and intervention opportunities.

Recent discoveries have highlighted the effects of oxytocin (OT) on social behavior and perception among autistic individuals. However, a gap persists in the literature regarding the potential effects of OT and the neural temporal dynamics due to OT administration. We explored the effect of OT on autistic individuals using magnetoencephalography (MEG), focusing on M100, M170, and M250, social perception-related components that tend to show atypical patterns in autistic individuals. Twenty-five autistic adolescents participated in this randomized, double-blind MEG study. Autistic individuals arrived at the lab twice and received an acute dose of intranasal OT or placebo in each session. During the scans, participants were asked to identify pictures of social and non-social stimuli. Additionally, 23 typically developing (TD) adolescents performed the same task in the MEG as a benchmark that allowed us to better characterize neural regions of interest and behavioral results for this age group in this task. A source-model beamformer analysis revealed that OT enhanced neural activity for social stimuli in frontal regions during M170. Additionally, in each of the preselected time windows, OT increased activation in the left hemisphere, regardless of the content of the presented stimuli. We suggest that OT increased the processing of social stimuli through two separate mechanisms. First, OT increased neural activity in a nonspecific manner, allowing increased allocation of attention toward the stimuli. Second, OT enhanced M170 activity in frontal regions only in response to social stimuli. These results reveal the temporal dynamics of the effects of OT on the early stages of social and non-social perception in autistic adolescents.Trial registration: This study was a part of a project registered as clinical trial October 27th, 2021. ClinicalTrials.gov Identifier: NCT05096676.

BACKGROUND: Fragile X syndrome (FXS) is the most frequent cause of inherited X-linked intellectual disability. Conventional FXS genetic testing methods mainly focus on FMR1 CGG expansions and fail to identify AGG interruptions, rare intragenic variants, and large gene deletions. METHODS: A long-range PCR and long-read sequencing-based assay termed comprehensive analysis of FXS (CAFXS) was developed and evaluated in Coriell and clinical samples by comparing to Southern blot analysis and triplet repeat-primed PCR (TP-PCR). RESULTS: CAFXS accurately detected the number of CGG repeats in the range of 93 to at least 940 with mass fraction of 0.5% to 1% in the background of normal alleles, which was 2-4-fold analytically more sensitive than TP-PCR. All categories of mutations detected by control methods, including full mutations in 30 samples, were identified by CAFXS for all 62 clinical samples. CAFXS accurately determined AGG interruptions in all 133 alleles identified, even in mosaic alleles. CAFXS successfully identified 2 rare intragenic variants including the c.879A > C variant in exon 9 and a 697-bp microdeletion flanking upstream of CGG repeats, which disrupted primer annealing in TP-PCR assay. In addition, CAFXS directly determined the breakpoints of a 237.1-kb deletion and a 774.0-kb deletion encompassing the entire FMR1 gene in 2 samples. CONCLUSIONS: Long-read sequencing-based CAFXS represents a comprehensive assay for identifying FMR1 CGG expansions, AGG interruptions, rare intragenic variants, and large gene deletions, which greatly improves the genetic screening and diagnosis for FXS.

15. Lisøy RS, Pfuhl G, Sunde HF, Biegler R. Sweet spot in music-Is predictability preferred among persons with psychotic-like experiences or autistic traits?. PLoS One;2022;17(9):e0275308.

People prefer music with an intermediate level of predictability; not so predictable as to be boring, yet not so unpredictable that it ceases to be music. This sweet spot for predictability varies due to differences in the perception of predictability. The symptoms of both psychosis and Autism Spectrum Disorder have been attributed to overestimation of uncertainty, which predicts a preference for predictable stimuli and environments. In a pre-registered study, we tested this prediction by investigating whether psychotic and autistic traits were associated with a higher preference for predictability in music. Participants from the general population were presented with twenty-nine pre-composed music excerpts, scored on their complexity by musical experts. A participant’s preferred level of predictability corresponded to the peak of the inverted U-shaped curve between music complexity and liking (i.e., a Wundt curve). We found that the sweet spot for predictability did indeed vary between individuals. Contrary to predictions, we did not find support for these variations being associated with autistic and psychotic traits. The findings are discussed in the context of the Wundt curve and the use of naturalistic stimuli. We also provide recommendations for further exploration.

16. Mahajan R, Sagar R. Adequate Management of Autism Spectrum Disorder in Children in India. Indian J Pediatr;2022 (Sep 29)

Despite the significant burden of neurodevelopmental disorders such as autism spectrum disorder (ASD) in India, there are areas of unmet needs at every level of the health care system. This includes screening and recognition, reliable and valid tools to evaluate, and to adequately manage ASD. There are also gaps in education and training of medical professionals, paraprofessionals, special education teachers and the related services. Lack of public awareness and cultural factors contribute to delays in early recognition and interventions. A framework is suggested to address these unmet needs at various levels to improve the care of these children with ASD. These include a) a focus on education of medical professionals, paraprofessionals, and teachers; b) setting up infrastructure at community, regional, and statewide levels, with adequate funding; and c) use of audiovisual technology and collaboration with international expertise.

17. Mandecka A, Regulska-Ilow B. The importance of nutritional management and education in the treatment of autism. Rocz Panstw Zakl Hig;2022;73(3):247-258.

Autism spectrum disorders (ASDs) are an early-onset neurodevelopmental disorders. The key symptoms of ASD include social deficits, verbal and non-verbal communication deficits, and restricted, repetitive patterns of behaviour, interests, or activities. Dietary patterns have been evidenced to be related to maternal nutritional status that might lead to different metabolic conditions, and maternal metabolic dysfunction has been observed to be associated with ASD. Furthermore growing evidence suggests that the gut microbiota has a role in the pathophysiology of ASD. Differences in composition of the gastrointestinal (GI) microbiota in children with ASD compared to unaffected siblings and/or healthy unrelated controls have been reported in various studies. The above-mentioned ASD factors and symptoms can be regulated by proper nutrition. The importance of nutrition and its possible impact on ASD patients is key to integral therapy. According to numerous research studies, various nutritional approaches succeeded in reducing the severity of patients’ core ASD symptoms. The numerous options for diet that is used in the ASD therapy, as described in the scientific literature, are related to the problem of choosing an appropriate nutritional treatment. Each nutrition programme needs to be personalised and tailored to an individual patient. The aim of the paper is to review the available literature on dietary interventions in children with ASD and provide up-to-date evidence.

OBJECTIVE: Assessing treatment fidelity in effectiveness research is critical to interpreting study findings. This paper details the development and initial psychometric evaluation of the Modular Evidence-Based Practices for Youth with Autism Fidelity Scale (MEYA-FS) designed to support the assessment of cognitive-behavioral treatments for youth with autism in effectiveness research. METHOD: Recorded treatment sessions (N = 338) were randomly selected from 77 youth (M age = 9.65 years, SD = 1.87; 50.67% White; 85.33% male) who received the Schema, Emotion, and Behavior-Focused Therapy for Children (SEBASTIEN) (n = 51) or Coping Cat (n = 24) program. RESULTS: The MEYA-FS Adherence items displayed acceptable interrater reliability, but more than half of the MEYA-FS Competence items did not. The magnitude and pattern of correlations supported the score validity of the MEYA-FS Adherence and Competence items and subscales. However, some corresponding Adherence and Competence items displayed significant overlap. Scores on each Adherence subscale distinguished between the SEBASTIEN and Coping Cat programs, providing support for discriminant validity. Finally, higher Adherence and Competence subscales predicted significant improvements in youth clinical outcomes (adjustment problems in the school setting, social-communication difficulties, restrictive/repetitive behaviors, and externalizing problems), providing initial evidence for predictive validity. CONCLUSIONS: The psychometric properties of the MEYA-FS make it appropriate for supporting efforts to evaluate cognitive-behavioral interventions for youth with autism in effectiveness and implementation research.

Social participation has been linked to healthy aging, yet little is known about social participation during extended periods of time for adults with intellectual and developmental disabilities. The social participation of 777 adults with intellectual and developmental disabilities (aged 18-77 years), during a 4-year period, was examined. Sociodemographic, physical, and behavioral health-related correlates of engagement in social participation were investigated. Findings indicated that the majority of adults with intellectual and developmental disabilities engaged in at least a moderate level of social participation during the 4-years. Employment status, physical health, and Special Olympics participation were associated with a higher level of social participation. Findings have implications for supports and services seeking to promote social participation opportunities for adults with intellectual and developmental disabilities.

Multiscale neural gradients reflect transdiagnostic effects of major psychiatric conditions on cortical morphology. Commun Biol;2022 (Sep 27);5(1):1024.

It is increasingly recognized that multiple psychiatric conditions are underpinned by shared neural pathways, affecting similar brain systems. Here, we carried out a multiscale neural contextualization of shared alterations of cortical morphology across six major psychiatric conditions (autism spectrum disorder, attention deficit/hyperactivity disorder, major depression disorder, obsessive-compulsive disorder, bipolar disorder, and schizophrenia). Our framework cross-referenced shared morphological anomalies with respect to cortical myeloarchitecture and cytoarchitecture, as well as connectome and neurotransmitter organization. Pooling disease-related effects on MRI-based cortical thickness measures across six ENIGMA working groups, including a total of 28,546 participants (12,876 patients and 15,670 controls), we identified a cortex-wide dimension of morphological changes that described a sensory-fugal pattern, with paralimbic regions showing the most consistent alterations across conditions. The shared disease dimension was closely related to cortical gradients of microstructure as well as neurotransmitter axes, specifically cortex-wide variations in serotonin and dopamine. Multiple sensitivity analyses confirmed robustness with respect to slight variations in analytical choices. Our findings embed shared effects of common psychiatric conditions on brain structure in multiple scales of brain organization, and may provide insights into neural mechanisms of transdiagnostic vulnerability.

BACKGROUND: Conventional dental care is often impossible in patients with Autism Spectrum Disorder (ASD). Non-collaborative behaviors, sometimes associated with aggressiveness, are usual justifications for premedication in this population. Thereby, this research focuses on the effects of oral midazolam versus oral ketamine plus midazolam as preanesthetic medication in ASD. METHODS: The sample included 64 persons with ASD, aged 2-59 years, scheduled for dental care under general anesthesia. The primary objective of this study was to compare degrees of sedation between two parallel, double-blinded, equally proportional groups randomized to receive oral midazolam (0.5 mg.kg(-1), maximum 15 mg) or oral midazolam (0.5 mg.kg(-1)) associated with oral S(+)-ketamine (3 mg.kg(-1), maximum 300 mg). The secondary outcomes were the need of physical stabilization to obtain intravenous line, awakening time, and occurrence of adverse events. RESULTS: According to the dichotomous analysis of sedation level (Ramsay score 1 and 2 versus Ramsay ≥ 3), oral association of S(+)-ketamine and midazolam improved sedation, with increased probability of Ramsay ≥ 3, Relative Risk (RR) = 3.2 (95% Confidence Interval [95% CI] = 1.32 to 7.76) compared to midazolam alone. Combined treatment also made it easier to obtain venous access without physical stabilization, RR = 2.05 (95% CI = 1.14 to 3.68). There were no differences between groups regarding awakening time and the occurrence of adverse events. CONCLUSION: The association of oral S(+)-ketamine with midazolam provides better preanesthetic sedation rates than midazolam alone and facilitates intravenous line access in patients with autism.

OBJECTIVE: Although many autistic adults show high posttraumatic stress, PTSD is underdiagnosed in this population. This study aims to examine correlates of autistic adults screening positive for PTSD (PTSD +) and predictors of a professional PTSD diagnosis (Diagnosis +) in the PTSD + subgroup. METHOD: Self-identified autistic adults (N = 677) completed an online survey on their demographic characteristics, mental health symptoms, and trauma history. T tests and chi-squares were used to compare subgroups, and logistic regression was used to predict diagnosis status. RESULTS: PTSD + participants were less likely to be employed or to identify as cisgender men, had more mental health symptoms and worse functional impairment, and had experienced a higher number of traumas and more interpersonal trauma. The same was true for Diagnosis + participants, who were also older and more likely to have a marginalized racial/ethnic identity. Among participants who were PTSD +, older age, being a woman or gender minority, being unemployed or on disability, having increased posttraumatic stress, having more co-occurring conditions, and having lower functional impairment predicted being Diagnosis +. The final model explained 35% of variance in diagnosis. CONCLUSION: PTSD is associated with significant impairment in autistic adults, but it often goes unrecognized. In particular, autistic cisgender men might be underdiagnosed with PTSD because of gendered stereotypes. High functional impairment may also increase barriers to obtaining an appropriate diagnosis. Future research should include participant treatment history as a potential factor. Clinicians should be aware of these potential signs of PTSD and diagnostic barriers when working with autistic clients. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

BACKGROUND: An individual with autism spectrum disorder (ASD) has social skill, motor skill, and motion perception deficits. However, the relationship among them was not clarified. Therefore, this study aimed to evaluate the effects of motor skills on social skills and motion perception. METHODS: Five typically developed children and fourteen children with ASD participated in our study. The N200 component, a brain activity indicating motion perception, was induced in mid-temporal (MT/V5) brain area by watching a random dot kinematograph, and was recorded using a scalp electroencephalogram. Furthermore, the social responsiveness scale (SRS) indicating the social skill deficit, the developmental coordination disorder questionnaire (DCDQ) estimating the developmental coordination disorder (DCD), and the movement assessment battery for children second edition (MABC-2) indicating motor skills were recorded in the children with ASD. A hierarchical multiple regression analysis was conducted to examine the modulation effects of motor skills on the relationship between social skills and motion perception. The dependent variable was the N200 latency, and the independent variables were SRS, MABC-2, and combined MABC-2 and SRS. RESULTS: The N200 latency was more delayed in children with ASD relative that in typically developed children. Intact balance ability modulated the relationship between social skills and N200 latency in children with ASD. Within the high balance ability, when the social skills worsened, the N200 latency was shortened. CONCLUSIONS: This is the first report that intact motor skills could modulate the relationship between social skills and motion perception.

Sensory features are part of the diagnostic criteria for autism and include sensory hypo/hyper reactivity and unusual sensory interest; however, additional sensory differences, namely differences in sensory integration, have not been routinely explored. This study characterized sensory integration differences in a cohort of children (n = 93) with a confirmed diagnosis of autism (5-9 years) using a standardized, norm-referenced battery. Mean z scores, autism diagnostic scores, and IQ are reported. Participants showed substantial deficits in tactile perception, praxis, balance, visual perception, and visual-motor skills. Relationship with autism diagnostic test scores were weak or absent. Findings suggest additional sensory difficulties that are not typically assessed or considered when characterizing sensory features in autism. These data have implications for a greater understanding of the sensory features in the autism phenotype and the development of personalized treatments.

There are increasing efforts to scale up services globally for families raising children with developmental disabilities (DDs). Existing interventions, often developed in high income, Western settings, need substantial adaptation before they can be implemented in different contexts. The aim of this study was to explore perspectives on the role that context plays in the adaptation and implementation of interventions targeting caregivers of children with DDs across settings. The study question was applied to the Caregiver Skills Training (CST) programme of the World Health Organization specifically, as well as to stakeholder experiences with caregiver interventions more broadly. Two focus group discussions (FGDs; n = 15 participants) and 25 individual semi-structured interviews were conducted. Participants were caregivers of children with DDs and professionals involved in adapting or implementing the CST across five continents and different income settings. Data were analysed thematically. Four main themes were developed: 1) Setting the scene for adaptations; 2) Integrating an intervention into local public services; 3) Understanding the reality of caregivers; 4) Challenges of sustaining an intervention. Informants thought that contextual adaptations were key for the intervention to fit in locally, even more so than cultural factors. The socio-economic context of caregivers, including poverty, was highlighted as heavily affecting service access and engagement with the intervention. Competing health priorities other than DDs, financial constraints, and management of long-term collaborations were identified as barriers. This study validates the notion that attention to contextual factors is an essential part of the adaptation of caregiver interventions for children with DDs, by providing perspectives from different geographical regions. We recommend a stronger policy and research focus on contextual adaptations of interventions and addressing unmet socio-economic needs of caregivers.

For autistic young adults, deciding whether to disclose their autism at work is complex. Minimal research explores what they need to support disclosure and what influences decisions. To understand disclosure needs and influencers, we explored (i) disclosure decision-making experiences and (ii) perceptions of the disclosure process among autistic young adults. We conducted focus groups using the Capability, Opportunity, Motivation, Behaviour Model and Theoretical Domains Framework (TDF). We analyzed data from 23 participants and mapped onto the TDF to develop five themes: (1) workplace environment, (2) perceptions of disclosure outcomes, (3) personal factors and identity, (4) disclosure-related ambitions and determination, and (5) know-hows of disclosure. Future work should prioritize developing disclosure decision-making supports and investigate employer roles in fostering inclusive workplaces.
