PURPOSE: Autism Spectrum Disorder (ASD) occurs in 1-1.5% of the general population and possibly in up to 20% of psychiatric outpatients. Post Traumatic Stress Disorder (PTSD) occurs at some point in life in 4% of the general population and in 14-20% of psychiatric outpatients. Knowledge about how PTSD manifests in people with ASD is important in order for it to be correctly diagnosed and intervened for. METHODS: This study investigated the relationship between PTSD and autism among adult psychiatric outpatients (N = 90) of whom 63 had ASD or subthreshold ASD based on DSM-5 criteria. The study group was subjected to in-depth psychiatric assessments using validated instruments. Diagnosis of PTSD was made based on the Mini International Neuropsychiatric Interview (MINI). RESULTS: There was a trend towards PTSD being more common among participants with ASD compared to participants without ASD, although significant differences could not be shown in this small sample. 21% of the ASD group had current PTSD, compared to 4% of the study group without ASD. There were no differences between the groups regarding exposure to trauma. There was a trend towards a relationship between number of autism symptoms and hyperarousal symptoms in PTSD. Conversely, the PTSD symptom of irritability/outbursts of anger, was significantly associated with number of autism symptoms. CONCLUSIONS: A subgroup of psychiatric outpatients with ASD also suffer from PTSD. Hyperarousal symptoms are possibly more prevalent in the presentation of PTSD in individuals/patients with ASD compared to those without ASD.

Pathogenic variants in autism gene KATNAL2 cause hydrocephalus and disrupt neuronal connectivity by impairing ciliary microtubule dynamics. Proc Natl Acad Sci U S A. 2024; 121(27): e2314702121.

Enlargement of the cerebrospinal fluid (CSF)-filled brain ventricles (cerebral ventriculomegaly), the cardinal feature of congenital hydrocephalus (CH), is increasingly recognized among patients with autism spectrum disorders (ASD). KATNAL2, a member of Katanin family microtubule-severing ATPases, is a known ASD risk gene, but its roles in human brain development remain unclear. Here, we show that nonsense truncation of Katnal2 (Katnal2Δ17) in mice results in classic ciliopathy phenotypes, including impaired spermatogenesis and cerebral ventriculomegaly. In both humans and mice, KATNAL2 is highly expressed in ciliated radial glia of the fetal ventricular-subventricular zone as well as in their postnatal ependymal and neuronal progeny. The ventriculomegaly observed in Katnal2Δ17 mice is associated with disrupted primary cilia and ependymal planar cell polarity that results in impaired cilia-generated CSF flow. Further, prefrontal pyramidal neurons in ventriculomegalic Katnal2Δ17 mice exhibit decreased excitatory drive and reduced high-frequency firing. Consistent with these findings in mice, we identified rare, damaging heterozygous germline variants in KATNAL2 in five unrelated patients with neurosurgically treated CH and comorbid ASD or other neurodevelopmental disorders. Mice engineered with the orthologous ASD-associated KATNAL2 F244L missense variant recapitulated the ventriculomegaly found in human patients. Together, these data suggest KATNAL2 pathogenic variants alter intraventricular CSF homeostasis and parenchymal neuronal connectivity by disrupting microtubule dynamics in fetal radial glia and their postnatal ependymal and neuronal descendants. The results identify a molecular mechanism underlying the development of ventriculomegaly in a genetic subset of patients with ASD and may explain persistence of neurodevelopmental phenotypes in some patients with CH despite neurosurgical CSF shunting.

3. Eken A, Nassehi F, Eroğul O. Diagnostic machine learning applications on clinical populations using functional near infrared spectroscopy: a review. Rev Neurosci. 2024; 35(4): 421-49.

Functional near-infrared spectroscopy (fNIRS) and its interaction with machine learning (ML) is a popular research topic for the diagnostic classification of clinical disorders due to the lack of robust and objective biomarkers. This review provides an overview of research on psychiatric diseases by using fNIRS and ML. Article search was carried out and 45 studies were evaluated by considering their sample sizes, used features, ML methodology, and reported accuracy. To our best knowledge, this is the first review that reports diagnostic ML applications using fNIRS. We found that there has been an increasing trend to perform ML applications on fNIRS-based biomarker research since 2010. The most studied populations are schizophrenia (n = 12), attention deficit and hyperactivity disorder (n = 7), and autism spectrum disorder (n = 6) are the most studied populations. There is a significant negative correlation between sample size (>21) and accuracy values. Support vector machine (SVM) and deep learning (DL) approaches were the most popular classifier approaches (SVM = 20) (DL = 10). Eight of these studies recruited a number of participants more than 100 for classification. Concentration changes in oxy-hemoglobin (ΔHbO) based features were used more than concentration changes in deoxy-hemoglobin (ΔHb) based ones and the most popular ΔHbO-based features were mean ΔHbO (n = 11) and ΔHbO-based functional connections (n = 11). Using ML on fNIRS data might be a promising approach to reveal specific biomarkers for diagnostic classification.

AIMS: To analyze needs and requirements of Pediatric Physical Therapists (PPTs), parents, children and adolescents with and without developmental disabilities in the future use of an activity monitor prototype (AM-p) in everyday clinical practice. METHODS: Qualitative exploratory study with a thematic analysis approach, based on Braun and Clarke’s six steps. Codes derived from the analysis and central themes were collated, based on Fleuren et al.’s groupings of determinants. RESULTS: We interviewed 25 PPTs, 12 parents, and 12 children and adolescents. Within four groupings of determinants, we found nine themes: 1) development of information materials; 2) application: output visualization and ease of use; 3) design; 4) relevance and acceptance; 5) shared decision-making; 6) compatibility in daily living; 7) finances, 8) time, and 9) legislation and regulations. CONCLUSIONS: End-users have similar basic needs, with individual fine-tuning to be addressed during further development of the AM-p. A child-friendly design, information material, and an easy-to-use application to read and interpret results, need to be developed. Efficient training for PPTs is important for the use of the AM-p and analysis of results. Communication between PPTs and children as well as parents enhances shared decision-making. We recommend involving diverse end-users to enable maximum customization of the AM-p.

Many autism spectrum disorder (ASD)-associated genes act as transcriptional regulators (TRs). Chromatin immunoprecipitation sequencing (ChIP-seq) was used to identify the regulatory targets of ARID1B, BCL11A, FOXP1, TBR1, and TCF7L2, ASD-associated TRs in the developing human and mouse cortex. These TRs shared substantial overlap in the binding sites, especially within open chromatin. The overlap within a promoter region, 1-2,000 bp upstream of the transcription start site, was highly predictive of brain-expressed genes. This signature was observed in 96 out of 102 ASD-associated genes. In vitro CRISPRi against ARID1B and TBR1 delineated downstream convergent biology in mouse cortical cultures. After 8 days, NeuN+ and CALB+ cells were decreased, GFAP+ cells were increased, and transcriptomic signatures correlated with the postmortem brain samples from individuals with ASD. We suggest that functional convergence across five ASD-associated TRs leads to shared neurodevelopmental outcomes of haploinsufficient disruption.

6. Hauw JJ, Hausser-Hauw C, Barthélémy C. Synapse and primary cilia dysfunctions in Autism Spectrum Disorders. Avenues to normalize these functions. Rev Neurol (Paris). 2024.

AIM: An update on the plasticity of the brain networks involved in autism (autism spectrum disorders [ASD]), and the increasing role of their synapses and primary non-motile cilia. METHODS: Data from PubMed and Google on this subject, published until February 2024, were analyzed. RESULTS: Structural and functional brain characteristics and genetic particularities involving synapses and cilia that modify neuronal circuits are observed in ASD, such as reduced pruning of dendrites, minicolumnar pathology, or persistence of connections usually doomed to disappear. Proteins involved in synapse functions (such as neuroligins and neurexins), in the postsynaptic architectural scaffolding (such as Shank proteins) or in cilia functions (such as IFT-independent kinesins) are often abnormal. There is an increase in glutaminergic transmission and a decrease in GABA inhibition. ASD may occur in genetic ciliopathies. The means of modulating these specificities, when deemed useful, are described. INTERPRETATION: The wide range of clinical manifestations of ASD is strongly associated with abnormalities in the morphology, functions, and plasticity of brain networks, involving their synapses and non-motile cilia. Their modulation offers important research perspectives on treatments when needed, especially since brain plasticity persists much later than previously thought. Improved early detection of ASD and additional studies on synapses and primary cilia are needed.

INTRODUCTION: While parents’ and professionals’ perceptions regarding children with autism spectrum disorder (ASD) have been studied extensively, limited data regarding the perspectives of children with ASD on their needs and the challenges they face are available. The study aimed to examine how children with ASD understand their condition and the aims of the interventions they undergo. METHODS: Nineteen children and adolescents (ages 5.7-14.2 years) formally diagnosed with ASD, with borderline to high intelligence (range 70-140), and able to converse verbally were interviewed in person at a child development clinic. A qualitative approach was used to capture children’s perceptions of their strengths and challenges and their understanding of a novel ASD treatment. The interview included direct and projective open-ended questions on each topic. Interpretive content analysis was used to evaluate the children’s answers. Medical data were extracted from medical records. The children’s parents completed questionnaires on their children’s disability levels, awareness of ASD diagnosis, and sociodemographic details. FINDINGS: Children spoke of their embodied sensations and feelings and discussed « normality » vs. « disability. » They varied in their awareness of their diagnosis/symptoms, and only one boy named his diagnosis and described its consequences in detail. Most children lacked an understanding of the educational and therapeutic aspects of the goals set for them. DISCUSSION AND CONCLUSIONS: Children with ASD are aware of their unique emotional and behavioral challenges. Nevertheless, they are frequently excluded from the process of patient information provision and lack an understanding of the goals of interventions. Findings suggest the need to explore developmentally and emotionally adaptive ways to involve children with ASD in discussions of their condition and possible interventions.

BACKGROUND: Early identification of suspected developmental delays (SDDs) is crucial for planning early interventions. This study aimed to determine the prevalence of SDDs and the associated determinants in children aged 12 months in the northeast of Iran, using the Age and Stage Questionnaire-3 (ASQ-3) as the evaluative tool. METHODS: This study conducted an analytical cross-sectional design to investigate all children who had completed the ASQ-3 screening form at 12 months of age within the time frame of 2016-2023 in the northeast of Iran. The necessary data were extracted from the electronic health record database associated with Mashhad University of Medical Sciences. To examine the factors associated with SDDs within each domain of the ASQ-3, a multiple logistic regression model was employed, and the results were presented using ORs along with 95% CIs. RESULTS: Over 7 years, 236 476 children (96.74%) underwent routine ASQ-3 screening at 12 months. After excluding certain cases, 226 076 children (95.60%) were included. Among them, 51 593 children (22.82%) had a score below -1 SD, indicating SDD prevalence in at least one domain. The social-personal domain had the highest prevalence with 22 980 children (10.16%), while the gross motor domain had the lowest with 5650 children (2.50%). Logistic regression analysis identified strong predictors of SDDs, including hospitalisation at birth (OR=1.85, 95% CI:1.69 to 2.02), prematurity (OR=1.56, 95% CI: 1.37 to 1.79), urbanisation (OR=1.51, 95% CI: 1.45 to 1.57), boys (OR=1.36, 95% CI: 1.31 to 1.40) and lack of exclusive breast feeding until 6 months (OR=1.30, 95% CI: 1.25 to 1.34). CONCLUSION: The prevalence of SDDs highlights the urgency for prompt action, while considering contributing factors. Policymakers can address modifiable risk factors associated with SDDs, including urbanisation risks, support programmes for immigrant families and the importance of exclusive breast feeding until 6 months. Additionally, it is recommended establishing gender-specific local standard cut-off points for the ASQ.

9. Krzysztofik K. Does a high threshold of sensory responsiveness affect the development of pretend play in children on the autism spectrum?. J Neurodev Disord. 2024; 16(1): 34.

BACKGROUND: Among the current avenues of research into the origins and development of the autism spectrum, those concerning atypical levels of sensory responsiveness are gaining increasing relevance. Researchers note the relationship of sensory responsiveness in children on the autism spectrum to their motor, cognitive and social development. Current research reports combines the responsiveness to sensory stimuli also with the development of pretend play. Aim of this study was to verify the relationship between the level of development of pretend play and the level of sensory responsiveness in children on the autism spectrum. METHODS: A study was conducted in a group of 63 children with a diagnosis of autism spectrum aged from 3 years and 7 months to 9 years and 3 months using: Pretend Play subscale from the Theory of Mind Mechanism Scale and Sensory Experiences Questionnaire version 2.1. RESULTS: The results revealed that elevated sensory hyporesponsiveness predicted low pretend play skills in the group of participating children. CONCLUSION: The study verified the contribution of the level of sensory hyporesponsiveness to explaining the atypical development of pretend play in children on the autism spectrum.

AIM: Adults with intellectual and developmental disabilities (IDD) have a significantly higher prevalence of Type 2 diabetes than the general population. Evidence that lifestyle and/or behavioural interventions, such as participation in Special Olympics, decreases the risk of developing diabetes in adults with IDD could help minimize health disparities and promote overall health in this population. METHODS: This was a 20-year retrospective cohort study of adults with IDD (30-39 years) in the province of Ontario, Canada, that compared hazard rates of diabetes among Special Olympics participants (n = 4145) to non-participants (n = 31,009) using administrative health databases housed at ICES. Using cox proportional hazard models, crude and adjusted hazard ratios were calculated for the association between the primary independent variable (Special Olympics participation status) and the dependent variable (incident diabetes cases). RESULTS: After controlling for other variables, the hazard ratio comparing rates for developing diabetes between Special Olympics participants and non-participants was 0.85. This represents a 15% reduction in the hazard among Special Olympics participants when followed for up to 20 years. This result was statistically significant and represents a small effect size. CONCLUSIONS: Special Olympics could be considered a complex intervention that promotes physical activity engagement through sport participation, health screenings, and the promotion of healthy eating habits through educational initiatives. This study provides evidence that Special Olympics participation decreases the rate for developing diabetes.

This study examined the differences between children and adolescents with autism spectrum disorder (ASD) and neurotypically developing (NTD) in terms of balance, postural control, and motor skills. It also examined which motor skills are most affected and whether scores on different assessment tests in ASD children are correlated. A cross-sectional observational study with two research groups was conducted. Timed up and go test (TUG), short form of Bruininks-Oseretsky test of Motor Proficiency version 2 (SFBOT-2), and pediatric balance scale (PBS) were used. A total of 100 participants 50 with ASD and 50 with NTD engaged in the research. Statistically significant differences were obtained between control group and ASD group in TUG test and in SFBOT-2 standard score and total score (p-value = <0.01). A statistically significant difference (p-value = <0.01) was seen between ASD group's and control group's PBS scores. Poor correlation was noted between TUG and SFBOT-2, as well as between PBS and TUG. A moderate correlation was also found between SFBOT-2 and PBS. Children with ASD present difficulties in motor skills and in static and dynamic balance compared to children with NTD. Differences were observed in the motor skills of strength followed by manual dexterity, running speed and agility, fine motor precision, fine motor integration, and balance. The PBS item that showed the greatest difference between the ASD group and control group was maintaining monopodial support with hands on hips. Finally, poor to moderate correlations were obtained between the different tests with statistically significant differences.

Hypnotic treatment improves sleep architecture and EEG disruptions and rescues memory deficits in a mouse model of fragile X syndrome. Cell Rep. 2024; 43(6): 114266.

Fragile X syndrome (FXS) is associated with disrupted cognition and sleep abnormalities. Sleep loss negatively impacts cognitive function, and one untested possibility is that disrupted cognition in FXS is exacerbated by abnormal sleep. We tested whether ML297, a hypnotic acting on G-protein-activated inward-rectifying potassium (GIRK) channels, could reverse sleep phenotypes and disrupted memory in Fmr1(-/y) mice. Fmr1(-/y) mice exhibit reduced non-rapid eye movement (NREM) sleep and fragmented NREM architecture, altered sleep electroencephalogram (EEG) oscillations, and reduced EEG coherence between cortical areas; these are partially reversed following ML297 administration. Treatment following contextual fear or spatial learning restores disrupted memory consolidation in Fmr1(-/y) mice. During memory recall, Fmr1(-/y) mice show an altered balance of activity among hippocampal principal neurons vs. parvalbumin-expressing interneurons; this is partially reversed by ML297. Because sleep disruption could impact neurophysiological phenotypes in FXS, augmenting sleep may improve disrupted cognition in this disorder.

INTRODUCTION: Children with atopic dermatitis (AD) are more at risk for the neurodevelopmental disorders attention-deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (ASD) with parallel increases in global prevalences. Children afflicted with these conditions appear to share similar problems in sensory modulation but investigational studies on the underlying aetiology are scarce. This scoping review aims to find knowledge gaps, collate hypotheses and to summarise available evidence on the shared pathophysiology of AD, ADHD and ASD in children. METHODS AND ANALYSIS: Our study will follow the methodological manual published by the Joanna Briggs Methodology for Scoping Reviews and will be reported in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analyses Extension for Scoping Reviews. The following electronic databases will be searched for studies focused on children with AD and symptoms of ADHD and/or ASD: Medline ALL via Ovid, Embase, Web of Science Core Collection and the Cochrane Central Register of Controlled Trials via Wiley. ETHICS AND DISSEMINATION: This review does not require ethics approval as it will not be conducted with human participants. We will only use published data. Our dissemination strategy includes peer review publication and conference reports.

Frontal Cortex Hyperactivation and Gamma Desynchrony in Fragile X Syndrome: Correlates of Auditory Hypersensitivity. bioRxiv. 2024.

Fragile X syndrome (FXS) is an X-linked disorder that often leads to intellectual disability, anxiety, and sensory hypersensitivity. While sound sensitivity (hyperacusis) is a distressing symptom in FXS, its neural basis is not well understood. It is postulated that hyperacusis may stem from temporal lobe hyperexcitability or dysregulation in top-down modulation. Studying the neural mechanisms underlying sound sensitivity in FXS using scalp electroencephalography (EEG) is challenging because the temporal and frontal regions have overlapping neural projections that are difficult to differentiate. To overcome this challenge, we conducted EEG source analysis on a group of 36 individuals with FXS and 39 matched healthy controls. Our goal was to characterize the spatial and temporal properties of the response to an auditory chirp stimulus. Our results showed that males with FXS exhibit excessive activation in the frontal cortex in response to the stimulus onset, which may reflect changes in top-down modulation of auditory processing. Additionally, during the chirp stimulus, individuals with FXS demonstrated a reduction in typical gamma phase synchrony, along with an increase in asynchronous gamma power, across multiple regions, most strongly in temporal cortex. Consistent with these findings, we observed a decrease in the signal-to-noise ratio, estimated by the ratio of synchronous to asynchronous gamma activity, in individuals with FXS. Furthermore, this ratio was highly correlated with performance in an auditory attention task. Compared to controls, males with FXS demonstrated elevated bidirectional frontotemporal information flow at chirp onset. The evidence indicates that both temporal lobe hyperexcitability and disruptions in top-down regulation play a role in auditory sensitivity disturbances in FXS. These findings have the potential to guide the development of therapeutic targets and back-translation strategies.

15. Schoondermark F, Spek A, Kiep M. Evaluating an Autistic Burnout Measurement in Women. J Autism Dev Disord. 2024.

This study evaluated the suitability of an unpublished autistic burnout assessment tool, focusing on autistic women. Distinguishing autistic burnout from conditions like depression or anxiety is crucial for effective interventions, emphasizing the need for nuanced research and refined measures in understanding and addressing autistic burnout. The Dutch version of the AASPIRE Autistic Burnout Measure (AABM-NL) was evaluated within a sample of 45 autistic women from the Autism Expertise Center. Preliminary findings of the AABM-NL scores demonstrated promising evidence of good internal consistency and convergent validity. Positive associations were observed between AABM-NL scores and a Likert scale assessing identification with autistic burnout, as well as with an instrument measuring physical and psychological complaints (SCL-90-R; Symptom Checklist-90-Revised). Specifically, anxiety, somatization, cognitive-performance deficits, and depression were correlated with the severity of autistic burnout. There was no significant difference between work status and the severity of autistic burnout, implying no employment-related connection. The AABM-NL effectively differentiated between women with and without autistic burnout, with 62 points as a suitable cut-off point. However, these results may not be generalized to women requiring daily living support, individuals beyond outpatient psychiatric settings, or those in institutionalized populations. The preliminary findings provide empirical evidence supporting the use of the AABM-NL as a potential tool for assessing autistic burnout in women receiving outpatient psychiatric care. Its implementation may contribute to programs aimed at recognizing and preventing autistic burnout in women. Further research is needed to enhance intervention strategies for mitigating the risk of autistic burnout.

BACKGROUND: Children living in food insecure households have poorer mental health outcomes compared with their food-secure peers; however, the relationship between the severity of food insecurity and diagnosed mental health conditions in young children remains unknown. This study examined the association between household food insecurity and reported diagnosed mental health conditions among children aged 5-11 years in Canada. METHODS: This study included 16 216 children aged 5-11 years living in Canada, from the 2019 Canadian Health Survey on Children and Youth. We measured household food insecurity using the Household Food Security Survey Module. We measured diagnosed mental health conditions by parent/caregiver report of health professional-diagnosed anxiety, depression, autism spectrum disorder or attention-deficit/hyperactive disorder. We developed a multivariable logistic regression model to assess the association between severities of food insecurity and mental health, controlling for potentially confounding variables. RESULTS: 17.0% of children lived in households reporting some level of food insecurity (5.4% marginal, 8.0% moderate and 3.6% severe). The prevalence of at least one diagnosed mental health condition in the same population was 10.9%. After adjusting for sociodemographic characteristics, children from marginal, moderate and severe food insecure households had a 1.39 (95% CI 0.99 to 1.97), 1.46 (95% CI 1.13 to 1.89) and 1.67 (95% CI 1.18 to 2.35) increased odds of having a diagnosed mental health condition, respectively. CONCLUSION: Household food insecurity is associated with an increased presence of diagnosed mental health conditions in children aged 5-11 years. This study adds to the body of research showing that social and economic inequities, including household food insecurity, negatively impact the health of children.

18. Wadley C, Stagnitti K. Implementation of Learn to Play Therapy for Children in Special Schools. Am J Occup Ther. 2024; 78(4).

IMPORTANCE: Play is the primary occupation in childhood and fundamental to occupational therapy practice. OBJECTIVE: To evaluate a play intervention in special school settings. DESIGN: Pre- and postinvolvement of a 7-mo play program. SETTING: Four special schools in Victoria, Australia, for children with IQs < 70. PARTICIPANTS: Thirty-eight children with diagnoses including intellectual disability, autism, and global developmental delay, 7 teachers, 2 speech pathologists, and 2 occupational therapists. INTERVENTION: Learn to Play Therapy for 1 hr per week over a 7-mo period. OUTCOMES AND MEASURES: Pre-post outcome measures included children's pretend play skills, language, social skills, emotional regulation, and academic competence. RESULTS: Mean age of 38 children (15 girls and 23 boys) at baseline was 5 yr 7 mo (SD = 0.46 yr). Results showed significant changes in children's pretend play (p = .03), ability to recall sentences (p = .02), social skills (p = .022), and academic competence (p = .012). Learn to Play had a large effect on children's narrative skills (d = 2.72). At follow-up, object substitution at baseline influenced expressive language (p < .001), narrative mean language utterance (MLU; p = .015), social skills (p < .001), and academic competence (p < .001); elaborate play at baseline plus time influenced social skills (p < .001); and elaborate play at baseline influenced narrative MLU (p =. 016), sentence recall (p = .009), and academic competence (p = .001). CONCLUSIONS AND RELEVANCE: Embedding pretend play within practice positively influenced children's language, narrative, social, and academic skills. Plain-Language Summary: This study adds to the limited research on play-based therapy programs in special school settings for children with an IQ of less than 70. Children participated in Learn to Play Therapy, during which an occupational therapist, who has observed and assessed the child's play and understands the child's play abilities, played beside the child. Learn to Play Therapy is a child-centered therapy that is used to increase a child's ability to self-initiate and enjoy pretend play. The positive impacts of supporting the children's pretend play ability were highlighted by increases in their pretend play, language, social skills, academic competence, and narrative language after participating in Learn to Play Therapy in their special schools.
