Purpose: The co-occurrence of autism spectrum disorder (ASD) and attention- deficit/hyperactivity disorder (ADHD) is significant and associated with a host of negative outcomes. Studies investigating social functioning in the presence of the ASD/ADHD co-occurrence have produced mixed findings. The present study further evaluated the impact of co-occurring ADHD on social functioning among youth with ASD and compared treatment response to a social competence intervention between youth with ASD and ASD + ADHD. Methods: Two-way repeated measures analyses of variance (ANOVAs) were computed with diagnostic group and time as the independent variables and measures of social functioning as dependent variables. Group and Time effects and Group by Time interactions were examined. Results: Youth with co-occurring ADHD displayed more impairments related to social awareness, but not in other social areas. Participants in both the ASD and ASD + ADHD groups demonstrated significant improvement following a social competence intervention. Conclusion: Co-occurring ADHD did not negatively affect treatment response. Youth with ASD + ADHD may benefit highly structured interventions with a scaffolded teaching design.

Research suggests that challenges associated with raising a child with an Autism Spectrum Disorder (ASD) can increase parents' risk for diminished parenting self-efficacy (PSE) and psychological wellbeing. The present study aimed to explore interrelationships between noteworthy predictors of PSE and parental psychological distress, including parental mastery beliefs and the co-parenting relationship amongst 122 Australian parents of children with autism. Results indicated that greater mastery beliefs and more favourable co-parenting relationships predicted greater PSE, and higher PSE predicted less psychological distress. PSE significantly mediated relationships between mastery beliefs and psychological distress, and between the co-parenting relationship and psychological distress. Findings have implications that can aid professionals to more effectively support parents raising children on the autism spectrum. [ABSTRACT FROM AUTHOR]

Presently, the combination of graph convolutional networks (GCN) with resting-state functional magnetic resonance imaging (rs-fMRI) data is a promising approach for early diagnosis of autism spectrum disorder (ASD). However, the prevalent approach involves exclusively full-brain functional connectivity data for disease classification using GCN, while overlooking the prior information related to the functional connectivity of brain subnetworks associated with ASD. Therefore, in this study, the multiple functional connectivity–based graph convolutional network (MFC-GCN) framework is proposed, using not only full brain functional connectivity data but also the established functional connectivity data from networks of key brain subnetworks associated with ASD, and the GCN is adopted to acquire complementary feature information for the final classification task. Given the heterogeneity within the Autism Brain Imaging Data Exchange (ABIDE) dataset, a novel External Attention Network Readout (EANReadout) is introduced. This design enables the exploration of potential subject associations, effectively addressing the dataset's heterogeneity. Experiments were conducted on the ABIDE dataset using the proposed framework, involving 714 subjects, and the average accuracy of the framework was 70.31%. The experimental results show that the proposed EANReadout outperforms the best traditional readout layer and improves the average accuracy of the framework by 4.32%. [ABSTRACT FROM AUTHOR]

(1) Background: Parents of children with autism spectrum disorders often experience psychological distress, which can affect the quality of childcare they provide. It is crucial to screen for psychiatric symptoms among these parents. The core symptom index (CSI) is a widely recognized tool used to assess general symptoms, including depression, anxiety, and somatic issues. It has proven validity and reliability across diverse Thai populations. Given the cultural similarities between Thai and Chinese populations, the CSI has been successfully implemented within the Chinese population. Nevertheless, it is crucial to research its validity and reliability in the general Chinese population. This study aimed to investigate the psychometric properties of the Chinese version of the CSI among parents of children with autism spectrum disorders using confirmatory factor analysis (CFA). (2) Methods: A total of 794 Chinese parents raising children with autism participated in this study. All completed the CSI, along with the social inhibition subscale of the Interpersonal Problems Inventory and the Couple Satisfaction Index. Factorial validity was assessed using CFA to determine how well the bifactor three-factor model fits the data. Various structural models were compared using model fit indices. Convergent and discriminant validity were examined by exploring correlations with the social inhibition subscale and the Couple Satisfaction Index. Invariance testing of the CSI was conducted across multiple groups based on gender, age, and education using CFA. The reliability of the CSI was evaluated using McDonald's omega coefficients. (3) Results: The bifactor model emerged as the best-fitting model for the data, suggesting that the total score of the CSI adequately represents overall psychiatric symptoms. The CSI exhibited significant correlations with the social inhibition subscale (r = 0.41, p < 0.01) and smaller correlation coefficients with the Couple Satisfaction Index (r = −0.16, p < 0.05), indicating both convergent and discriminant validity. The invariant test results support scalar invariance levels based on gender and age but only partial invariance for education. The Chinese version of the CSI demonstrated high consistency, with McDonald's omega coefficients ranging between 0.86 and 0.95. (4) Conclusions: The bifactor model of the Chinese version of the CSI is validated, making it a suitable tool for measuring depression, anxiety, and somatization symptoms among parent(s) of children with autism spectrum disorders. Further research on other Chinese populations is encouraged. [ABSTRACT FROM AUTHOR]

Co-occurring psychiatric conditions are very common in tic disorders and Tourette syndrome. These additional symptoms are often detrimental to quality of life and may impact upon the implementation and efficacy of evidence-based behavioural therapies (BT) for tics. Combining a review of the available literature, relevant theory, and expert clinical practice, we present a guideline for implementing behavioural and psychosocial interventions when common comorbidities are present. These include attention-deficit hyperactivity disorder (ADHD), obsessive–compulsive disorder (OCD), anxiety, disruptive behaviour, autism spectrum disorder (ASD) and depression. Practical recommendations are provided for assessment, formulation and management of specific and multiple comorbidities in BT for both children and adults. Despite comorbidities being common in tic disorders, few studies have comprehensively addressed how they may influence the efficacy or implementation of existing therapies or how such treatments may need to be modified or sequenced. We outline recommendations for future research, including randomised control trials of BT for those with specific or multiple comorbidities, as well as adequately powered sub-group analyses within larger scale trials or naturalistic study designs. Transdiagnostic models of psychiatric disorders and treatment, including modular cross-diagnostic therapies, which recognise the dimensionality of psychiatric disorders are also highlighted as an important focus in treatment development in tic disorders.

Schizophrenia and autism spectrum disorders (ASD) were considered as two neurodevelopmental disorders and had shared clinical features. we hypothesized that they have some common atypical brain functions and the purpose of this study was to explored the shared brain spontaneous activity strength alterations in early onset schizophrenia (EOS) and ASD in the children and adolescents with a multi-center large-sample study. A total of 171 EOS patients (aged 14.25 ± 1.87), 188 ASD patients (aged 9.52 ± 5.13), and 107 healthy controls (aged 11.52 ± 2.82) had scanned with Resting-fMRI and analyzed surface-based amplitude of low-frequency fluctuations (ALFF). Results showed that both EOS and ASD had hypoactivity in the primary sensorimotor regions (bilateral primary and early visual cortex, left ventral visual stream, left primary auditory cortex) and hyperactivity in the high-order transmodal regions (bilateral SFL, bilateral DLPFC, right frontal eye fields), and bilateral thalamus. EOS had more severe abnormality than ASD. This study revealed shared functional abnormalities in the primary sensorimotor regions and the high-order transmodal regions in EOS and ASD, which provided neuroimaging evidence of common changes in EOS and ASD, and may help with better early recognition and precise treatment for EOS and ASD.

PROTACs, proteolysis targeting chimeras, are bifunctional molecules inducing protein degradation through a unique proximity-based mode of action. While offering several advantages unachievable by classical drugs, PROTACs have unfavorable physicochemical properties that pose challenges in application and formulation. In this study, we show the solubility enhancement of two PROTACs, ARV-110 and SelDeg51, using Poly(vinyl alcohol). Hereby, we apply a three-fluid nozzle spray drying set-up to generate an amorphous solid dispersion with a 30% w/w drug loading with the respective PROTACs and the hydrophilic polymer. Dissolution enhancement was achieved and demonstrated for t = 0 and t = 4 weeks at 5 °C using a phosphate buffer with a pH of 6.8. A pH shift study on ARV-110-PVA is shown, covering transfer from simulated gastric fluid (SGF) at pH 2.0 to fasted-state simulated intestinal fluid (FaSSIF) at pH 6.5. Additionally, activity studies and binding assays of the pure SelDeg51 versus the spray-dried SelDeg51-PVA indicate no difference between both samples. Our results show how modern enabling formulation technologies can partially alleviate challenging physicochemical properties, such as the poor solubility of increasingly large 'small' molecules.

Background: In families of individuals with autism spectrum disorder (ASD), the added difficulties they face may influence their perception of family quality of life (FQoL). It is important to identify factors which foster their perceived wellbeing and are susceptible to intervention. Our aim was to explore the association between mindful attention and FQoL in these families controlling their perceived social support. Method: Ninety-six parents of people with ASD were evaluated using the Mindful Attention and Awareness Scale (MAAS), the Support Questionnaire for Parents with Children with Disability, and the Spanish Family Quality of Life Scale for families with underage members with intellectual and developmental disabilities. Results: Multiple regression analyses revealed that high levels of mindful attention positively predicted FQoL after controlling the influence of social support. Conclusions: Practical implications are discussed in terms of family support interventions. We conclude that mindful attention interventions may be useful for families with children and adolescents with ASD to improve their FQoL. [ABSTRACT FROM AUTHOR]

It could be argued that autistic females, attending high school, have a distinct set of needs when compared to their male counterparts. The purpose of this review is to synthesise reported findings on what could be considered as effective for supporting the needs of autistic females in high school settings. The review adhered to PRISMA guidelines. Searches identified 12 papers that included direct perspectives of autistic females, their families and the professionals supporting them. Data were analysed using thematic synthesis. The findings indicate seven main themes for support related to: mental health; identification of specific needs and post‐diagnostic support; friendship interventions and skills development; tiered support; relationships between home and school; transitions between levels of education; self, peer and staff advocacy, and sense of belonging. Social and emotional experiences of autistic females in high school are key areas to target in ensuring successful education. Findings are discussed in relation to integrated, inclusive practices that high schools may adopt to support this cohort of students. Implications for professional practice, policy and research are discussed, which will be of interest to educators and helping professionals alike. [ABSTRACT FROM AUTHOR]

Background and Aims: Autism spectrum disorder (ASD) is a complex neurodevelopmental condition characterized by a wide range of symptoms and challenges. While ASD is primarily associated with atypical social and communicative behaviors, increasing research has pointed towards the involvement of various brain regions, including the cerebellum. This review article aims to provide a comprehensive overview of the role of cerebellar lobules in ASD, highlighting recent findings and potential therapeutic implications. Methods: Using published articles found in PubMed, Scopus, and Google Scholar, we extracted pertinent data to complete this review work. We have searched for terms including anatomical insights, neuroimaging, neurobiological, and autism spectrum disorder. Results: The intricate relationship between the cerebellum and other brain regions linked to ASD has been highlighted by neurobiological research, which has shown abnormalities in neurotransmitter systems and cerebellar circuitry. The relevance of the cerebellum in the pathophysiology of ASD has been further highlighted by anatomical studies that have revealed evidence of cerebellar abnormalities, including changes in volume, morphology, and connectivity. Conclusion: Thorough knowledge of the cerebellum's function in ASD may lead to new understandings of the underlying mechanisms of the condition and make it easier to create interventions and treatments that are more specifically targeted at treating cerebellar dysfunction in ASD patients.

Autism spectrum disorder (ASD) is a medical illness that markedly impacts the neurological function. An Individual with autism experiences challenges in acknowledging their names actively avoids establishing eye contact and demonstrates a limited capacity to express emotions. Biomedical image categorization is an important area of study that is increasingly popular among both researchers and clinicians for the purpose of detecting and diagnosing ASD disorders. The human face can function as a biological indicator since it has the ability to reflect the condition of the brain. Hence, it may be employed as a convenient and uncomplicated instrument for the early detection of ASDs. This research uses a variety of advanced techniques to detect individuals who have autism by analyzing their facial images. A range of deep learning (DL) models, including VGG16, InceptionV3, and EfficientnetB0, is used to identify autistic children by utilizing facial expressions detection. The research is carried out to empirically determine the optimal settings for the model optimizer and different hyperparameters in DL models with the goal of improving prediction accuracy. A conventional research dataset sourced from Kaggle comprising 2940 images of children analyzed as both having and not having autism is used to assess the DL models. The improved VGG16 model attained a 95% accuracy rate on the test dataset. The findings of the present study suggest that the improved VGG16 model outperforms the models created by prior studies. and can aid clinicians in validating the precision of their first assessment of ASD in pediatric patients.

The formation of the human gut microbiome initiates in utero, and its maturation is established during the first 2–3 years of life. Numerous factors alter the composition of the gut microbiome and its functions, including mode of delivery, early onset of breastfeeding, exposure to antibiotics and chemicals, and maternal stress, among others. The gut microbiome–brain axis refers to the interconnection of biological networks that allow bidirectional communication between the gut microbiome and the brain, involving the nervous, endocrine, and immune systems. Evidence suggests that the gut microbiome and its metabolic byproducts are actively implicated in the regulation of the early brain development. Any disturbance during this stage may adversely affect brain functions, resulting in a variety of neurodevelopmental disorders (NDDs). In the present study, we reviewed recent evidence regarding the impact of the gut microbiome on early brain development, alongside its correlation with significant NDDs, such as autism spectrum disorder, attention-deficit/hyperactivity disorder, Tourette syndrome, cerebral palsy, fetal alcohol spectrum disorders, and genetic NDDs (Rett, Down, Angelman, and Turner syndromes). Understanding changes in the gut microbiome in NDDs may provide new chances for their treatment in the future. [ABSTRACT FROM AUTHOR]

In the field of neuroimaging, more studies of abnormalities in brain regions of the autism spectrum disorder (ASD) usually focused on two brain regions connected, and less on abnormalities of higher-order interactions of brain regions. To explore the complex relationships of brain regions, we used the partial entropy decomposition (PED) algorithm to capture higher-order interactions by computing the higher-order dependencies of all three brain regions (triads). We proposed a method for examining the effect of individual brain regions on triads based on the PED and surrogate tests. The key triads were discovered by analyzing the effects. Further, the hypergraph modularity maximization algorithm revealed the higher-order brain structures, of which the link between right thalamus and left thalamus in ASD was more loose compared with the typical control (TC). Redundant key triad (left cerebellum crus 1 and left precuneus and right inferior occipital gyrus) exhibited a discernible attenuation in interaction in ASD, while the synergistic key triad (right cerebellum crus 1 and left postcentral gyrus and left lingual gyrus) indicated a notable decline. The results of classification model further confirmed the potential of the key triads as diagnostic biomarkers. [ABSTRACT FROM AUTHOR]

Background: Observational studies have indicated a correlation between immunological inflammation and the risk of autism spectrum disorder (ASD). However, the causal relationship between immunological inflammation and ASD remains uncertain. Methods: Immunity-wide data sources were retrieved from the GWAS catalog. Genetic summary data on ASD were retrieved from two independent GWAS. We performed two independent bi-directional, two-sample Mendelian randomization (MR) analyses and a meta-analysis based on the two independent MR estimates to assess the causal relationship between ASD and immune cell signatures. Results: We have discovered 26 potential correlations between genetic predisposition in the immunophenotypes and ASD. The meta-analysis of the two inverse variance weighted (IVW)-produced estimates provided further evidence supporting the potential causal relationship between immunophenotypes and ASD. Based on the findings of the reverse MR analysis, it was determined that there are two potential negative causal relationships between ASD and immunophenotypes. However, the meta-analysis of the two IVW-derived MR estimates indicated that immunophenotypes were not significantly influenced by ASD (OR = 0.87, 95% CI = 0.73 -1.03, P = 0.09; OR = 0.91, 95% CI = 0.81–1.01, P = 0.08). Conclusions: This study expanded immune cell subtypes that were potentially causally associated with ASD risk as well as identified ASD-specific immune cell subtypes. The discovery has the potential to lead to earlier detection and more effective treatment techniques. [ABSTRACT FROM AUTHOR]

Background: The VPS50 protein functions in synaptic and dense core vesicle acidification, and perturbations of VPS50 function produce behavioral changes in Caenorhabditis elegans. Patients with mutations in VPS50 show severe developmental delay and intellectual disability, characteristics that have been associated with autism spectrum disorders (ASDs). The mechanisms that link VPS50 mutations to ASD are unknown. Results: To examine the role of VPS50 in mammalian brain function and behavior, we used the CRISPR/Cas9 system to generate knockouts of VPS50 in both cultured murine cortical neurons and living mice. In cultured neurons, KO of VPS50 did not affect the number of synaptic vesicles but did cause mislocalization of the V-ATPase V1 domain pump and impaired synaptic activity, likely as a consequence of defects in vesicle acidification and vesicle content. In mice, mosaic KO of VPS50 in the hippocampus altered synaptic transmission and plasticity and generated robust cognitive impairments. Conclusions: We propose that VPS50 functions as an accessory protein to aid the recruitment of the V-ATPase V1 domain to synaptic vesicles and in that way plays a crucial role in controlling synaptic vesicle acidification. Understanding the mechanisms controlling behaviors and synaptic function in ASD-associated mutations is pivotal for the development of targeted interventions, which may open new avenues for therapeutic strategies aimed at ASD and related conditions.

AbstractIndependent component analysis (ICA) is widely used to estimate spatial resting-state networks and their time courses in neuroimaging studies. It is thought that independent components correspond to sparse patterns of co-activating brain locations. Previous approaches for introducing sparsity to ICA replace the non-smooth objective function with smooth approximations, resulting in components that do not achieve exact zeros. We propose a novel Sparse ICA method that enables sparse estimation of independent source components by solving a non-smooth non-convex optimization problem via the relax-and-split framework. The proposed Sparse ICA method balances statistical independence and sparsity simultaneously and is computationally fast. In simulations, we demonstrate improved estimation accuracy of both source signals and signal time courses compared to existing approaches. We apply our Sparse ICA to cortical surface resting-state fMRI in school-aged autistic children. Our analysis reveals differences in brain activity between certain regions in autistic children compared to children without autism. Sparse ICA selects coactivating locations, which we argue is more interpretable than dense components from popular approaches. Sparse ICA is fast and easy to apply to big data. Supplementary materials for this article are available online, including a standardized description of the materials available for reproducing the work. [ABSTRACT FROM AUTHOR]

Background: We aimed to examine the hypothesized negative associations between childbirth post-traumatic stress disorder (PTSD) symptoms (using the two-factor model of birth-related and general symptoms), social support, and a couple's relationship quality at 8-12 weeks postpartum. This analysis considered the longitudinal positive shared variance with acute stress disorder (ASD) symptoms measured shortly after birth, while accounting for obstetric and demographic variables. Methods: Participants included 246 mothers who gave birth at the maternity ward of a tertiary healthcare center. Self-report questionnaires were used 1-4 days postpartum (T1): Demographic information, the Birth Satisfaction Scale-Revised (BSS-R), and the National Stressful Events Survey Acute Stress Disorder Short Scale (NSESSS). At T2 (8-12 weeks postpartum), the Multidimensional Scale of Perceived Social Support (MSPSS), the Dyadic Adjustment Scale (DAS-7), and the City Birth Trauma Scale (BiTS). Results: In partial support of our hypotheses, three hierarchical regression analyses revealed a significant positive contribution of ASD symptoms to childbirth PTSD general symptoms (β = .33, p <.001) and the total score (β = .29, p <.001), but not to birth-related symptoms. Social support (β = -.21, p = .003) and the quality of the couple's relationship (β=-.20, p = .003) showed negative associations with the BiTS general symptoms. Conclusion: Our study enhances understanding of the shared variance between childbirth ASD and PTSD, supporting the factor structure of general and birthrelated symptoms as different aspects of childbirth PTSD and highlighting the negative association of social support and the quality of a couple's relationship with PTSD general symptoms, suggesting potential avenues for targeted interventions.

Shared book-reading (SBR) is a commonplace interaction in the home, yet for families with autistic children, little is known about the types of books parents read with their children, their frequency of reading these books, or how this routine relates to those in families with non-autistic children. This study thus compared the frequency of SBR amongst parents of autistic/non-autistic children, focusing on various book genres (narrative, informational, alphabet, wordless). We also took parents’ variables (age, education, self-efficacy) into consideration. Participants were 216 parents (183 mothers, 33 fathers): 74 with autistic children (Mage = 6.56, SD = 1.33), and 142 without an autism diagnosis (Mage = 4.79, SD = 1.30). Parents of autistic children read wordless picturebooks, narratives, and alphabet books significantly more frequently with their children than those without autism, with no significant differences in terms of overall frequency of SBR. Understanding how these variables relate and interact can facilitate the creation of programmes that more effectively support families’ promotion of children’s literacy development, especially children with autism.

Background: The brain cortex is responsible for many higher-level cognitive functions. Disruptions during cortical development have long-lasting consequences on brain function and are associated with the etiology of brain disorders. We previously found that the protein tyrosine phosphatase receptor delta Ptprd, which is genetically associated with several human neurodevelopmental disorders, is essential to cortical brain development. Loss of Ptprd expression induced an aberrant increase of excitatory neurons in embryonic and neonatal mice by hyper-activating the pro-neurogenic receptors TrkB and PDGFRβ in neural precursor cells. However, whether these alterations have long-lasting consequences in adulthood remains unknown. Results: Here, we found that in Ptprd+/- or Ptprd-/- mice, the developmental increase of excitatory neurons persists through adulthood, affecting excitatory synaptic function in the medial prefrontal cortex. Likewise, heterozygosity or homozygosity for Ptprd also induced an increase of inhibitory cortical GABAergic neurons and impaired inhibitory synaptic transmission. Lastly, Ptprd+/- or Ptprd-/- mice displayed autistic-like behaviors and no learning and memory impairments or anxiety. Conclusions: These results indicate that loss of Ptprd has long-lasting effects on cortical neuron number and synaptic function that may aberrantly impact ASD-like behaviors. [ABSTRACT FROM AUTHOR]

Background: Increased parental self-efficacy has been found to have positive effects on parental skills and stress levels, as well as behavioural outcomes for children. This is particularly relevant in relation to neurodivergent children and young people, who tend to present with more behavioural challenges related to emotion regulation difficulties. To assist with the issue of long wait times, a pilot parent group intervention was delivered to parents of children awaiting neurodevelopmental assessment who were presenting with emotion regulation difficulties. The aim of this study was to increase parental self-efficacy. Method: Psychoeducational parent group sessions were delivered online over five sessions to nine families. The sessions included psychoeducation around emotion regulation difficulties and strategies for managing these at home. Results: Parental self-efficacy scores significantly increased following intervention. Conclusions: Parental self-efficacy can be increased via group psychoeducation sessions aimed at understanding and improving emotion regulation. [ABSTRACT FROM AUTHOR]

Emerging research suggests that episodic memory challenges are commonly encountered by autistic individuals; however, the specific nature of these memory challenges remains elusive. Here, we address critical gaps in the literature by examining pattern separation memory, the ability to store distinct memories of similar stimuli, and its links to the core autistic trait of repetitive, restricted interests and behaviors. Utilizing a large sample of over 120 autistic children and well-matched non-autistic peers, we found that autistic children showed significantly reduced performance on pattern separation memory. A clustering analysis identified three distinct pattern separation memory profiles in autism, each characterized by reduced or increased generalization abilities. Importantly, pattern separation memory was negatively correlated with the severity of repetitive, restricted interest and behavior symptoms in autism. These findings offer new evidence for challenges in pattern separation memory in autism and emphasize the need to consider these challenges when assessing and supporting autistic individuals in educational and clinical settings. Memory challenges remain understudied in childhood autism. Our study investigates one specific aspect of memory function, known as pattern separation memory, in autistic children. Pattern separation memory refers to the critical ability to store unique memories of similar stimuli; however, its role in childhood autism remains largely uncharted. Our study first uncovered that the pattern separation memory was significantly reduced in autistic children, and then showed that reduced memory performance was linked to their symptoms of repetitive, restricted interest and behavior. We also identified distinct subgroups with profiles of reduced and increased generalization for pattern separation memory. More than 72% of autistic children showed a tendency to reduce memory generalization, focusing heavily on unique details of objects for memorization. This focus made it challenging for them to identify commonalities across similar entities. Interestingly, a smaller proportion of autistic children displayed an opposite pattern of increased generalization, marked by challenges in differentiating between similar yet distinct objects. Our findings advance the understanding of memory function in autism and have practical implications for devising personalized learning strategies that align with the unique memory patterns exhibited by autistic children. This study will be of broad interest to researchers in psychology, psychiatry, and brain development as well as teachers, parents, clinicians, and the wider public. [ABSTRACT FROM AUTHOR]

A lack of response to voices, and a great interest for music are part of the behavioral expressions, commonly (self-)reported in Autism Spectrum Disorder (ASD). These atypical interests for vocal and musical sounds could be attributable to different levels of acoustical noise, quantified in the harmonic-to-noise ratio (HNR). No previous study has investigated explicit auditory pleasantness in ASD comparing vocal and non-vocal sounds, in relation to acoustic noise level. The aim of this study is to objectively evaluate auditory pleasantness. 16 adults on the autism spectrum and 16 neuro-typical (NT) matched adults rated the likeability of vocal and non-vocal sounds, with varying harmonic-to-noise ratio levels. A group by category interaction in pleasantness judgements revealed that participants on the autism spectrum judged vocal sounds as less pleasant than non-vocal sounds; an effect not found for NT participants. A category by HNR level interaction revealed that participants of both groups rated sounds with a high HNR as more pleasant for non-vocal sounds. A significant group by HNR interaction revealed that people on the autism spectrum tended to judge as less pleasant sounds with high HNR and more pleasant those with low HNR than NT participants. Acoustical noise level of sounds alone does not appear to explain atypical interest for voices and greater interest in music in ASD. [ABSTRACT FROM AUTHOR]

The current study was a secondary analysis of cross-sectional data collected in New Zealand. Parents (n = 291) of an autistic child completed an online survey that included temporal/demographic questions relating to the parent and child, and parent ratings of the child's core ASD symptoms, their parenting stress, and psychological well-being. Child and parent ages were related to ASD core symptoms, parenting stress, and psychological well-being, the parent-child age gap was not. Diagnostic delay was only positively associated with parent depression and negatively associated with child communication impairment. Findings indicated that temporal variables can be predictive of parent well-being and child autism symptoms. The findings suggest that focusing interventions on communication abilities may have positive impacts parental mental health. [ABSTRACT FROM AUTHOR]

The current study aims to examine the factors that facilitate or act as barriers to the marital relationships of parents of children with ASD. In total, 150 parents of children with ASD participated in this study. An online qualitative survey tool was utilized to collect data, which were subsequently subjected to thematic analysis. Through qualitative analysis, three major themes emerged: (1) Psychological and Emotional Experiences, (2) Sense of Partnership, and (3) The Rich get Richer, including sub-themes such as formal support systems, a strong marital relationship prior to ASD diagnosis, and limited family resources. The findings suggest that elements of the marital relationship can serve as valuable resources for parents of children with ASD in coping with the challenges of parenthood. Conversely, the study highlights certain factors that act as barriers to the marital relationship. [ABSTRACT FROM AUTHOR]

To study whether milk is restricted/excluded from diets of Autism Spectrum Disorders (ASD) children in Mumbai and whether GFCF (gluten-free casein-free) diet is adhered to. Information regarding dietary restrictions, milk consumption, adherence to the GFCF diet, and gastrointestinal distress symptoms was obtained from parents of 50 ASD children. Mean age of children was 9.5 years and mean age at diagnosis was 3.1 years. Almost all parents considered milk healthy. Only nine parents were concerned about its purity and one parent considered it a causative factor. All children had consumed milk before ASD diagnosis, and 40 children continued to consume milk postdiagnosis without any adverse effects. 25% of parents were only aware of A1/A2 milk, but most did not know much. Fourteen parents had attempted the GFCF diet and 8 opined that it had benefitted their children. For many children, sugar was restricted to reduce hyperactivity. These findings indicate that milk is not restricted in the diets of ASD children, by parents or physicians. Parents who included milk did not observe worsening of symptoms. Since some studies have implicated the need to exclude milk from ASD children's diets, further studies are warranted, especially among Indian children. [ABSTRACT FROM AUTHOR]

Neurodevelopmental disorders such as autism spectrum disorder (ASD) and attention-deficit hyperactivity disorder (ADHD) are clinically distinct, yet share synaptic dysfunction as a common brain pathophysiology. Neurodegenerative diseases such as Huntington's disease (HD) entail a neuroinflammatory cascade of molecular and cellular events which can contribute to the death of neurons. Emerging roles for supportive glial cells such as microglia and astrocytes in the ongoing regulation of neural synapses and brain excitability raise the possibility that some of the synaptic pathology and/or inflammatory events could be a direct consequence of malfunctioning glial cells. Focusing on microglia, we cross-examined 12 recently published studies in which microglial dysfunction was induced/identified in a cell-autonomous manner and its functional consequence on neural development, brain volume, functional connectivity, inflammatory response and synaptic regulation were evaluated; in many cases, the onset of symptoms relevant to all three neurodevelopmental disorders were assessed behaviorally. Challenging the classic notion of microglial activation as an inflammatory response to neuropathology, our compilation clarifies that microglial dyshomeostasis itself can consequently disrupt neural homeostasis, leading to neuropathology and symptom onset. This further warranted defining the molecular signatures of context-specific microglial pathology relevant to human diseases. [ABSTRACT FROM AUTHOR]

Key Clinical Message: The key takeaway from this clinical scenario is to choose the most appropriate and reasonable treatment plan when dealing with a patient who has atrial septal defect (ASD) and concurrent atrial and mediastinal masses. In such cases, a heart‐oncology team should make the therapeutic decision. Right atrial masses are not pretty rare and might be a diagnostic challenge. Thrombosis, tumors, and vegetations are primary differential diagnoses. Workup for these masses usually includes multimodality imaging and biopsy in selected cases. We report a case of a 37‐year‐old lady who presented with cough, dyspnea, and head and neck swelling after a cesarean section. Echocardiography revealed a right atrial mass accompanied by a secundum type atrial septal defect (ASD). Pulmonary CT Angiography was performed, in which a lobulated mass in the anterior mediastinum was detected, and a heart‐oncology team made the therapeutic decision. The patient was scheduled for surgical ASD closure and concomitant tissue biopsy. The pathology results were in favor of poorly differentiated germ cell tumors, and chemotherapy was started following the surgery. After two sessions of chemotherapy, the tumor did not respond to the primary regimen. Thus, an updated regimen was initiated. Compliance with the updated regimen was acceptable, and the patient is currently under treatment and follow‐up. [ABSTRACT FROM AUTHOR]

Autism spectrum disorder (ASD) is a complex and highly variable neurodevelopmental disorder. This manuscript describes an observational study aimed at evaluating the impact of behavioral and pharmacological treatments on autistic patients at a Jordanian Autism Institution. Patients were evaluated every three months to assess their progress in behavioral treatment using the ABLLS (Assessment of Basic Language and Learning Skills) method, which evaluates 25 skills based on a child’s performance. The researcher collected all previous assessments and observed at least two evaluation periods. Males comprised 90.38% of the study population. Among psychiatric conditions, hyperactivity (36.54%) and irritability (30.77%) showed the highest prevalence. The first interval served as the baseline. Results from the second and third intervals showed slight differences but were not statistically significant. In contrast, the fourth interval demonstrated a statistically significant difference (P < 0.0001). In conclusion, combining pharmacological and behavioral treatments appears more beneficial than behavioral therapy alone, although this benefit may take at least a year to manifest effectively.

Autism spectrum disorder (ASD) is significantly known as social interaction impairment that can be reduced through early school-age intervention. The quasi-experimental research design was used to examine the effect of applied behavior analysis treatment on ASD children's interpersonal skills. The researchers used a purposive sampling technique to select 30 participants who have symptoms of ASD, which were divided into two groups (control and experimental) without gender discrimination. The assessment of basic language and learning skills (ABLLS-R) protocol and portage guide of early education was used to develop a questionnaire comprising four factors. The results indicate a statistically significant difference between the experimental and control groups in terms of students' interpersonal skills and the pretest and post-test scores of the experimental group. It is suggested that parents and therapists should develop a sharing ability among children with autism symptoms so they can understand social reinforcement. [ABSTRACT FROM AUTHOR]

Autism spectrum disorder (ASD) has been intensely investigated since the term was first used over 80 years ago. The prevalence of ASD is constantly rising, and, currently, 1:36 children are diagnosed with this disorder. Despite the intense interest in ASD, the origins of this disorder remain obscure. This article explores motor issues and proprioceptive interoception difficulties as the prodrome of ASD. The importance of early intervention in the prognosis of ASD is common knowledge. Yet, since the communicational and social behaviors typical of ASD are observable only after the age of 18 months, diagnosis and early intervention are delayed. Therefore, the quest into the involvement of sensory–motor difficulties as a source of ASD traits, or at least as a potential early indicator, is warranted, with the intention of enabling early diagnosis and early intervention. This article examines the justification for this new avenue of early diagnosis and intervention and may open up a completely different way of viewing ASD. This new point of view may suggest an original path of assessment and intervention in infancy with this group of clients, possibly leading to improved prognosis for children and their families.

Background: The prevalence of Autism Spectrum Disorder (ASD) in Indonesia was predicted to increase by 500 people annualy form 2010, and there are still many nutrition problems found in this group. Nutritional status in ASD is affected by several factors, including mother’s education level, parenting style, knowledge of balanced nutrition and parental income. Objectives: To analyze the relationship between mother’s education level, parenting style, knowledge of balanced diet and parental income on the nutritional status of persons with ASD in Special Schools in the JABODETABEK (Jakarta, Bogor, Depok, Tangerang, Bekasi) area. Methods: This study was an observational study with a cross-sectional design. The population in this study were people with ASD in Special Schools in the JABODETABEK area. Sampling was conducted using the Quota Sampling method, conducted in MarchMay 2023 with a total sample of 114 respondents. The data analysis used was the Spearman rank test. Results: Results showed that children and adolescent with ASD in our study had a good nutritional status (average Z-Score=0.81). The bivariate test shows that there was a fairly strong relationship between parenting style (p-value=0.007; r=0.250) and the nutritional status of children and adolescent with ASD. However, there was no relationship between the mother’s education level (p-value=0.949), knowledge of balanced diet (pvalue=0.728), and parental income (p-value=0.976) with the nutritional status of people with ASD. Conclusions: Parenting style shows a significant positive correlation with the nutritional status of people with ASD in Special Schools in the JABODETABEK area. [ABSTRACT FROM AUTHOR]

This review aimed to synthesize the group design literature to identify the evidence-based reading comprehension interventions for children with ASD. The primary aim was to identify which reading comprehension interventions had demonstrated positive effects for students with ASD in group design studies. This review was initiated using both PsychInfo and ERIC in October 2019 with a second review completed in April 2020. For studies to be included, they had to include pre-/post-data on a reading comprehension intervention and include students with ASD as well as to be (1) peer-reviewed, (2) written in English, and (3) published between 2000 and 2019. The decision to review articles from 2000 forward was based on the publication of the National Reading Panel report (2000) and the wealth of research on the Big Five areas of reading. Five studies were found that met criteria, with a total of 141 students and 87% of the intervention group meeting criteria for ASD. Results showed effectiveness for reading comprehension interventions using anaphoric questions, direct instruction, and comprehension training strategies. These instructional strategies are consistent with single-case design study findings showing efficacy for these strategies with individual students and are important in supporting the variability of executive functioning skills needed for integrating passage information with whole group instruction as well.

(1) Background and Objectives: This review aims to identify the latest literature on the possible effect of bilingualism on the linguistic skills of children with autism spectrum disorder (ASD) residing in Greece. (2) Materials and Methods: The literature was searched in the databases of Scopus and PubMed by selecting articles and by reviewing four studies published in peer-reviewed journals. This Scoping Review is based on the standards of PRISMA recommendations for scoping reviews, while the PCC framework was used as a guide to construct clear and meaningful objectives and eligibility criteria. (3) Results: The publications included in the review addressed a variety of language-related skills, including morphology, the syntax–pragmatics interface, narrative ability, as well as both receptive and expressive language skills. (4) Conclusions: Three out of four studies provide evidence that bilingual ASD children are not disadvantaged compared to monolingual peers but rather enjoy some benefits, to a certain extent, due to bilingualism. However, the number of the reviewed studies as well as the limitations of the studies themselves render this conclusion tentative. Additionally, the findings set guidelines that speech therapists, educators, psychologists, and doctors in the Greek context need to follow when treating or educating bilingual children with ASD.

Analyzing data from students in the NCES High School Longitudinal Study dataset, we drew upon expectancy-value theory to examine the role of student motivation (measured by self-efficacy, identity, utility, and interest), as mediators between 9th grade math test scores and final math GPA for autistic students. In predicting final high school math GPA, math identity was the strongest predictor for autistic students with above average test scores. Findings for autistic students contrast with results for non-autistic students whose final math GPA is strongly predicted by the direct effects of 9th grade test scores. These results suggest that seeing oneself as a math person may be particularly influential for autistic students with higher 9th grade math performance.

BackgroundAutism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by symptoms that include social interaction deficits, language difficulties and restricted, repetitive behavior. Early intervention through medication and behavioral therapy can eliminate some ASD-related symptoms and significantly improve the life-quality of the affected individuals. Currently, the diagnosis of ASD is highly limited.MethodsTo investigate the feasibility of early diagnosis of ASD, we tested extracellular vesicles (EVs) proteins obtained from ASD cases. First, plasma EVs were isolated from healthy controls (HCs) and ASD individuals and were analyzed using proximity extension assay (PEA) technology to quantify 1,196 protein expression level. Second, machine learning analysis and bioinformatic approaches were applied to explore how a combination of EV proteins could serve as biomarkers for ASD diagnosis.ResultsNo significant differences in the EV morphology and EV size distribution between HCs and ASD were observed, but the EV number was slightly lower in ASD plasma. We identified the top five downregulated proteins in plasma EVs isolated from ASD individuals: WW domain-containing protein 2 (WWP2), Heat shock protein 27 (HSP27), C-type lectin domain family 1 member B (CLEC1B), Cluster of differentiation 40 (CD40), and folate receptor alpha (FRalpha). Machine learning analysis and correlation analysis support the idea that these five EV proteins can be potential biomarkers for ASD.ConclusionWe identified the top five downregulated proteins in ASD EVs and examined that a combination of EV proteins could serve as biomarkers for ASD diagnosis.

This study examined the sensory profile of three groups of children (those with visual impairment, typical development or autism spectrum disorder) aged 3 to 12. The principal aim was to find out whether the Sensory Profile (SP) of children with visual impairment was a good predictor of behaviors typical of ASD. The data was collected through a sensory profile filled out by parents of 37 visually impaired children, 30 with autism spectrum disorder (ASD) and 42 with typical development (TD). To assess the risk of ASD, the Social Communication Questionnaire (SCQ) was also administered. The results indicate that children with visual impairment are at increased risk of exhibiting signs of ASD, and that the sensory profile is a good predictor of risk of autistic signs in children with visual impairment. This study provides for the first time strong evidence for the need to systematically assess the sensory profile in children with visual impairment.

Summary: Autism spectrum disorder (ASD) is a neurodevelopmental disorder (NDD) that affects approximately 4% of males and 1% of females in the United States. While causes of ASD are multi-factorial, single rare genetic variants contribute to around 20% of cases. Here, we report a case series of seven unrelated probands (6 males, 1 female) with ASD or another variable NDD phenotype attributed to de novo heterozygous loss of function or missense variants in the gene LARP1 (La ribonucleoprotein 1). LARP1 encodes an RNA-binding protein that post-transcriptionally regulates the stability and translation of thousands of mRNAs, including those regulating cellular metabolism and metabolic plasticity. Using lymphocytes collected and immortalized from an index proband who carries a truncating variant in one allele of LARP1, we demonstrated that lower cellular levels of LARP1 protein cause reduced rates of aerobic respiration and glycolysis. As expression of LARP1 increases during neurodevelopment, with higher levels in neurons and astrocytes, we propose that LARP1 haploinsufficiency contributes to ASD or related NDDs through attenuated metabolic activity in the developing fetal brain.

BackgroundAutism spectrum disorder (ASD) is a neurodevelopmental disorder (NDD) characterized by significant impairments in social, communicative, and behavioral abilities. However, only a limited number of studies address the genetic basis of ASD in the African population. This study aims to document the genes associated with ASD in Africa and the techniques used to identify them. Additionally, genes identified elsewhere but not yet in Africa are also noted.MethodsOnline databases such as Wiley Online Library, PubMed, and Africa Journal Online were used. The review was conducted using the keyword related to genetic and genomic ASD study in the African population.ResultIn this scoping review, 40 genetic studies on ASD in Africa were reviewed. The Egyptian and South African populations were the most studied, with 25 and 5 studies, respectively. Countries with fewer studies included Tunisia (4), East African countries (3), Libya (1), Nigeria (1), and Morocco (1). Some 61 genes responsible for ASD were identified in the African population: 26 were identified using a polymerase chain reaction (PCR)-based method, 22 were identified using sequencing technologies, and 12 genes and one de novo chromosomal aberration were identified through other techniques. No African study identified any ASD gene with genome-wide association studies (GWAS). Notably, at least 20 ASD risk genes reported in non-African countries were yet to be confirmed in Africa’s population.ConclusionThere are insufficient genetic studies on ASD in the African population, with sample size being a major limitation in most genetic association studies, leading to inconclusive results. Thus, there is a need to conduct more studies with large sample sizes to identify other genes associated with ASD in Africa’s population using high-throughput sequencing technology.

This review explores the clinical presentation of similarities and differences in Attention-Deficit/Hyperactivity Disorder (ADHD) and Autism Spectrum Disorder (ASD). This paper investigates the deficits in executive function, social function, and emotional intelligence that are seen in both conditions and how the presence of both conditions can exacerbate these deficiencies. Understanding the clinical presentations in these domains is critical to refine diagnostic methods and treatments and improve outcomes for those affected by these neurodevelopmental disorders. The similarities in clinical presentation between ADHD and ASD present a significant diagnostic challenge, with individuals often exhibiting similar behaviors and difficulty navigating the complexities that encompass reacting to their environment. Further research is paramount in gaining more knowledge of the disorders and challenges faced by these individuals, especially those with the presence of both conditions.
