Many males with FXS meet criteria for ASD. This study was designed to (1) describe ASD symptoms in adolescent and young adult males with FXS (n = 44) and (2) evaluate the contributions to ASD severity of cognitive, language, and psychiatric factors, as well as FMRP (the protein deficient in FXS). A few ASD symptoms on the ADOS-2 were universal in the sample. There was less impairment in restricted and repetitive behaviors (RRB) than in the social affective (SA) domain. The best predictor of overall ASD severity and SA severity was expressive syntactic ability. RRB severity was best predicted by the psychiatric factors. Implications for clinical practice and for understanding the ASD comorbidity in FXS are discussed.

2. Aran A, Cassuto H, Lubotzky A, Wattad N, Hazan E. {{Brief Report: Cannabidiol-Rich Cannabis in Children with Autism Spectrum Disorder and Severe Behavioral Problems-A Retrospective Feasibility Study}}. {Journal of autism and developmental disorders}. 2018.

Anecdotal evidence of successful cannabis treatment in autism spectrum disorder (ASD) are accumulating but clinical studies are lacking. This retrospective study assessed tolerability and efficacy of cannabidiol-rich cannabis, in 60 children with ASD and severe behavioral problems (age = 11.8 +/- 3.5, range 5.0-17.5; 77% low functioning; 83% boys). Efficacy was assessed using the Caregiver Global Impression of Change scale. Adverse events included sleep disturbances (14%) irritability (9%) and loss of appetite (9%). One girl who used higher tetrahydrocannabinol had a transient serious psychotic event which required treatment with an antipsychotic. Following the cannabis treatment, behavioral outbreaks were much improved or very much improved in 61% of patients. This preliminary study supports feasibility of CBD-based cannabis trials in children with ASD.

Does the belief that a face belongs to an individual with autism affect recognition of that face? To address this question, we used the inversion effect as a marker of face recognition. In Experiment 1, participants completed a recognition task involving upright and inverted faces labelled as either ‘regular’ or ‘autistic’. In reality, the faces presented in both conditions were identical. Results revealed a smaller inversion effect for faces labelled as autistic. Thus, simply labelling a face as ‘autistic’ disrupts recognition. Experiment 2 showed a larger inversion effect after the provision of humanizing versus dehumanizing information about faces labelled as ‘autistic’. We suggest changes in the inversion effect could be used as a measure to study stigma within the context of objectification and dehumanization.

Robots and virtual reality are gaining popularity in the intervention of children with autism spectrum disorder (ASD). To shed light on children’s attitudes towards robots and characters in virtual reality, this study aims to examine whether children with ASD show the uncanny valley effect. We varied the realism of facial appearance by morphing a cartoon face into a human face, and induced perceptual mismatch by enlarging the eyes, which has previously been shown as an effective method to induce the uncanny valley effect in adults. Children with ASD and typically developing (TD) children participated in a two-alternative forced choice task that asked them to choose one they liked more from the two images presented on the screen. We found that TD children showed the effect, i.e., the enlargement of eye size and the approaching realism reduced their preference. In contrast, children with ASD did not show the uncanny valley effect. Our findings in TD children help resolve the controversy in the literature about the existence of the uncanny valley effect among young children. Meanwhile, the absence of the uncanny valley effect in children with ASD might be attributed to their reduced sensitivity to subtle changes of face features and their limited visual experience to faces caused by diminished social motivation. Last, our findings provide practical implications for designing robots and virtual characters for the intervention of children with ASD.

Language development in typically developing children (TD) has traditionally been investigated in relation to environmental factors, while language in children with autism spectrum disorder (ASD) has primarily been related to child-based factors. We employ a longitudinal corpus of 32 preschoolers with ASD and 35 linguistically matched TD peers recorded over 6 visits (ranging between 2 and 5years of age) to investigate the relative importance of child-based and environmental factors in language development for both populations. We also investigate the reciprocal interaction between children’s response to parents’ input, and parents’ response to children’s production. We report six major findings. (1) Children’s production of word types, tokens, and MLU increased across visits, and were predicted by their Expressive Language (EL) (positively) and diagnosis (negatively) from Visit 1. (2) Parents’ production also increased across visits, and was predicted by their child’s nonverbal cognition (positively) and diagnosis (negatively) from Visit 1. (3) At all visits and across groups, children and parents matched each other in lexical and syntactic production; (4) Parents who produced longer MLUs during a given visit had children who produced more word types and tokens, and had longer MLUs, at the subsequent visit. (5) When both child EL at Visit 1 and parent MLU were included in the model, both contributed significantly to future child language; however, EL accounted for a greater proportion of the variance. (6) Finally, children’s speech significantly predicted parent speech at the next visit. Taken together, these results draw more attention to the importance of child-based factors in the early language development of TD children, and to the importance of parental language factors in the early language development of children with ASD.

Importance: Prenatal exposure to certain medications has been hypothesized to influence the risk of autism spectrum disorders (ASD). However, the underlying effects on the neurotransmitter systems have not been comprehensively assessed. Objective: To investigate the association of early-life interference with different neurotransmitter systems by prenatal medication exposure on the risk of ASD in offspring. Design, Setting, and Participants: This case-control study included children born from January 1, 1997, through December 31, 2007, and followed up for ASD until January 26, 2015, within a single Israeli health maintenance organization. Using publicly available data, 55 groups of medications affecting neurotransmitter systems and prescribed to pregnant women in this sample were identified. Children prenatally exposed to medications were compared with nonexposed children. Data were analyzed from March 1, 2017, through June 20, 2018. Main Outcome and Measures: Hazard ratios (HRs) and 95% CIs of ASD risk associated with exposure to medication groups using Cox proportional hazards regression, adjusted for the relevant confounders (eg, birth year, maternal age, maternal history of psychiatric and neurologic disorders, or maternal number of all medical diagnoses 1 year before pregnancy). Results: The analytic sample consisted of 96249 individuals (1405 cases; 94844 controls; mean [SD] age at the end of follow-up, 11.6 [3.1] years; 48.8% female), including 1405 with ASD and 94844 controls. Of 34 groups of medications, 5 showed nominally statistically significant association with ASD in fully adjusted models. Evidence of confounding effects of the number of maternal diagnoses on the association between offspring exposure to medication and ASD was found. Adjusting for this factor, lower estimates of ASD risk among children exposed to cannabinoid receptor agonists (HR, 0.72; 95% CI, 0.55-0.95; P = .02), muscarinic receptor 2 agonists (HR, 0.49; 95% CI, 0.24-0.98; P = .04), opioid receptor kappa and epsilon agonists (HR, 0.67; 95% CI, 0.45-0.99; P = .045), or alpha2C-adrenergic receptor agonists (HR, 0.43; 95% CI, 0.19-0.96; P = .04) were observed. Exposure to antagonists of neuronal nicotinic acetylcholine receptor alpha was associated with higher estimates of ASD risk (HR, 12.94; 95% CI, 1.35-124.25; P = .03). Conclusions and Relevance: Most of the medications affecting neurotransmitter systems in this sample had no association with the estimates of ASD risk. Replication and/or validation using experimental techniques are required.

8. Jia H, Yu D. {{Aberrant Intrinsic Brain Activity in Patients with Autism Spectrum Disorder: Insights from EEG Microstates}}. {Brain topography}. 2018.

Autism spectrum disorder (ASD) involves aberrant organization and functioning of large-scale brain networks. The aim of this study was to examine whether the resting-state EEG microstate analysis could provide novel insights into the abnormal temporal and spatial properties of intrinsic brain activities in patients with ASD. To achieve this goal, EEG microstate analysis was conducted on the resting-state EEG datasets of 15 patients with ASD and 18 healthy controls from the Healthy Brain Network. The parameters (i.e., duration, occurrence rate, time coverage and topographical configuration) of four classical microstate classes (i.e., class A, B, C and D) were statistically tested between two groups. The results showed that: (1) the occurrence rate and time coverage of microstate class B in ASD group were significantly larger than those in control group; (2) the duration of microstate class A, the duration and time coverage of microstate class C were significantly smaller than those in control group; (3) the map configuration and occurrence rate differed significantly between two groups for microstate class D. These results suggested that EEG microstate analysis could be used to detect the deviant functions of large-scale cortical activities in ASD, and may provide indices that could be used in clinical researches of ASD.

Reduced social motivation is a hallmark of individuals with autism spectrum disorders (ASDs). Although the exact neural mechanisms are unclear, oxytocin has been shown to enhance motivation and attention to social stimuli, suggesting a potential to augment social reinforcement learning as the central mechanism of behavioral interventions in ASD. We tested how reinforcement learning in social contexts and associated reward prediction error (RPE) signals in the nucleus accumbens (NAcc) were modulated by intranasal oxytocin. Male adults with a childhood diagnosis of ASD (n = 15) and healthy controls (n = 24; aged 18-26 years) performed a probabilistic reinforcement learning task during functional magnetic resonance imaging in a single-center (research center in Germany), randomized double-blind, placebo-controlled cross-over trial. The interventions were intranasal oxytocin (Syntocinon((R)), Novartis; 10 puffs = 20 international units (IUs) per treatment) and placebo spray. Using computational modeling of behavioral data, trial-by-trial RPE signals were assessed and related to brain activation in NAcc during reinforcing feedback in social and non-social contexts. The order of oxytocin/placebo was randomized for 60 participants. Twenty-one participants were excluded from analyses, leaving 39 for the final analysis. Behaviorally, individuals with ASD showed enhanced learning under oxytocin when the learning target as well as feedback was social as compared to non-social (social vs. non-social target: 87.09% vs. 71.29%, 95% confidence interval (CI): 7.28-24.33, p = .003; social vs. non-social feedback: 81.00% vs. 71.29%, 95% CI: 2.81-16.61, p = .027). Correspondingly, oxytocin enhanced the correlation of the RPE signal with NAcc activation during social (vs. non-social) feedback in ASD (3.48 vs. -1.12, respectively, 95% CI: 2.98-6.22, p = .000), whereas in controls, this effect was found in the placebo condition (2.90 vs. -1.14, respectively, 95% CI: 1.07-7.01, p = 0.010). In ASD, a similar pattern emerged when the learning target was social (3.00 vs. -0.64, respectively, 95% CI: -0.13 to 7.41, p = 0.057), whereas controls showed a reduced correlation for social learning targets under oxytocin (-0.70 vs. 2.72, respectively, 95% CI: -5.86 to 0.98, p = 0.008). The current data suggest that intranasal oxytocin has the potential to enhance social reinforcement learning in ASD. Future studies are warranted that investigate whether oxytocin can potentiate social learning when combined with behavioral therapies, resulting in greater treatment benefits than traditional behavior-only approaches.

OBJECTIVE: While it is generally accepted that adults with intellectual and developmental disabilities (IDDs) use health services to a greater extent than the general population, there is remarkably little research that focuses on the costs associated with their health care. Using population-based data from adults with IDD in Ontario, this study aimed to estimate overall health care costs, classify individuals into high and non-high cost categories and describe differences in the demographics, clinical profiles and health care use patterns between these groups. DESIGN: A retrospective cohort study based in Ontario, Canada, was conducted with the use of linked administrative health data. METHODS: A costing algorithm developed for the general population in Ontario was applied to estimate health care costs of adults with IDD under age 65 for 2009 and 2010. Individuals were categorised into two groups according to whether their total annual health care costs were among the highest decile in the general population. These groups were compared on demographic and clinical variables, and relative mean costs for six types of health care services in the two groups were computed. In addition, we computed the proportion of individuals who remained in the high cost group over 2 years. RESULTS: Among adults with IDD, 36% had annual health care expenditures greater than $2610 CAD (top decile of all Ontario adults under 65). These individuals were more likely to be female, to be in the oldest age groups, to live in group homes and to be receiving disability income support than individuals whose expenditures were below the high cost threshold. In addition, they had higher rates of all the physical and mental health conditions studied. Greatest health care expenses were due to hospitalisations, especially psychiatric hospitalisations, continuing care/rehabilitation costs and medication costs. The majority of individuals whose health care costs placed them in the high cost category in 2009 remained in that category a year later. DISCUSSION: Adults with IDD are nearly 4 times as likely to incur high annual health care costs than those without IDD. Individuals with IDD and high health care costs have unique health and demographic profiles compared with adults with IDD whose annual health care costs are below the high cost threshold. Attending to their health care needs earlier in their health care trajectory may be an opportunity to improve health and reduce overall health care costs. It is important that we explore how to best meet their needs. Models proposed to meet the needs of adults with high health care costs in the general population may not apply to this unique group.

11. Maras K, Marshall I, Sands C. {{Mock Juror Perceptions of Credibility and Culpability in an Autistic Defendant}}. {Journal of autism and developmental disorders}. 2018.

One-hundred-and-sixty jury-eligible participants read a vignette describing a male who was brought to the attention of police for suspicious and aggressive behaviours and displayed atypical behaviours in court. Half of participants were informed that he had autism spectrum disorder (ASD) and were given background information about ASD; the other half received no diagnostic label or information. The provision of a label and information led to higher ratings of the defendant’s honesty and likeability, reduced blameworthiness, and resulted in fewer guilty verdicts, and more lenient sentencing. Thematic analysis revealed that participants in the label condition were more empathetic and attributed his behaviours to his ASD and mitigating factors, while participants in the No label condition perceived the defendant as deceitful, unremorseful, rude and aggressive.

The insular cortex, hidden within the lateral sulcus of the human brain, participates in a range of cognitive, affective, and sensory functions. Autism spectrum disorder (ASD), a neurodevelopmental condition affecting all of these functional domains, has increasingly been linked with atypical activation and connectivity of the insular cortices. Here we review the latest research linking atypical insular function to a range of behaviors characteristic of ASD, with an emphasis on neuroimaging findings in the domains of social cognition and executive function. We summarize some of the recent work linking the insula to interventions in autism, including oxytocin-based pharmacological treatments and music therapy. We suggest that future directions likely to yield significant insights into insular pathology in ASD include the analysis of the dynamics of this brain region. We also conclude that more basic research is necessary on the use of oxytocin pharmacotherapy, and larger studies addressing participant heterogeneity are needed on the use of music therapy in ASD. Long-term studies are needed to ascertain sustained effects of these interventions.

Heredity has a major role in autism spectrum disorder (ASD), yet underlying causal genetic variants have been defined only in a fairly small subset of cases. The enormous genetic heterogeneity associated with ASD emphasizes the importance of identifying convergent pathways and molecular mechanisms that are responsible for this disorder. We review how recent transcriptomic analyses have transformed our understanding of pathway convergence in ASD. In particular, deep RNA sequencing coupled with downstream investigations has revealed that a substantial fraction of autistic brains possess distinct transcriptomic signatures. These signatures are in part a consequence of altered neuronal activity and have a particular impact on pre-mRNA alternative splicing patterns.

Broad Autism Phenotype (BAP) refers to the characteristics and behaviour patterns similar to the defining features of Autism Spectrum Disorder (ASD) which are sub-threshold but still qualitatively similar to ASD. Broad Autism Phenotype Questionnaire (BAPQ) has been established to be reliable tool for assessing BAP which has been translated in different languages. In this article, we describe adaptation and standardization of BAPQ in Hindi, a widely spoken language in India. The questionnaire was translated into Hindi adhering to the International Test Commission Guidelines. The reliability coefficient obtained using Cronabch’s Alphas was moderate (0.608). The self report translated version was then administered to 96 parents of children diagnosed with ASD. 68 participants scored over the cutoff to indicate presence of BAP in them. Their responses on BAPQ were analysed through confirmatory factor analysis. Factor analysis revealed different factor structure than given in the original scale. Therefore, based on the findings, a brief scale of BAP is proposed.

16. Stralin P, Hetta J. {{First episode psychosis and comorbid ADHD, autism and intellectual disability}}. {European psychiatry : the journal of the Association of European Psychiatrists}. 2018; 55: 18-22.

BACKGROUND: Comorbidity between neurodevelopmental disorders and psychotic disorders is common, but little is known about how neurodevelopmental disorders influence the presentation and outcome of first episode psychosis. METHODS: A nation-wide cohort (n = 2091) with a first hospitalization for psychosis between 2007-2011 and at ages between 16-25 at intake was identified from Swedish population registries. Comorbid diagnoses of neurodevelopmental disorders were identified at first psychosis hospitalization and for ADHD also by dispensations of psychostimulants before the first psychosis hospitalization. Data from the registers on hospitalizations and dispensations of antipsychotic and psychostimulant medications during the year before and 2 years after the first psychosis hospitalization were analysed. Self-harm and substance use disorders were identified by ICD10 codes at hospitalizations. RESULTS: 2.5% of the cohort was identified with a diagnosis of intellectual disability, 5.0% with autism and 8.1% with ADHD. A larger proportion of cases with Autism (OR = 1.8, p < 0.05) and intellectual disability (OR = 3.1, p < 0.01) were using antipsychotic medication year 2 compared to the rest of the cohort. Delusional disorder was more common in the autism group (OR = 2.3, p < 0.05) at first psychosis hospitalization. ADHD was associated with higher risks for substance use disorders and self-harm both before and after the first psychosis hospitalization. Year 2 substance use disorder had a OR = 2.6 (p < 0.001) and self-harm OR = 4.1 (p < 0.001). CONCLUSIONS: Psychosis with comorbid ADHD is associated with high risks for substance use disorders and for self-harm, while psychosis with comorbid autism and intellectual disability is associated with longer treatment and higher doses of antipsychotic medication.

The objective of the study was to investigate the association between catatonia in autism spectrum disorder (ASD) and the levels of hair and serum trace elements and minerals in children with ASD. The levels of hair and serum trace elements and minerals of boys suffering from ASD with (n = 30) and without (n = 30) catatonia, as well as 30 age- and sex-matched neurotypical controls were assessed using ICP-MS. Hair calcium (Ca) and selenium (Se) levels were lower in ASD patients as compared to the controls. Hair mercury (Hg) levels in ASD patients were more than 3-fold and 2-fold higher as compared to the controls and children with catatonia in ASD. Hair iodine (I) and manganese (Mn) were the lowest and the highest in ASD + Catatonia, respectively. Serum aluminium (Al) and cadmium (Cd) levels in healthy controls were significantly higher in comparison to the patients of both groups. Serum chromium (Cr), copper (Cu) levels were significantly increased in patients with ASD and catatonia, whereas vanadium (V) levels were elevated in patients both with and without catatonia. Multiple regression analysis demonstrated that hair Hg and serum Al and Cd levels were negatively associated with catatonia in ASD in crude and adjusted models. Although the etiology of catatonia in ASD is unclear, the obtained data demonstrate that catatonic symptoms in ASD may be at least partially mediated by altered trace element levels. Further studies are required to elucidate the role of trace elements in the potential signaling mechanisms of catatonia.

In typical development, listeners can use semantic content of verbs to facilitate incremental language processing-a skill that is associated with existing language skills. Studies of children with ASD have not identified an association between incremental language processing in semantically-constraining contexts and language skills, perhaps because participants were adolescents and/or children with strong language skills. This study examined incremental language processing and receptive language in young children with ASD with a range of language skills. Children showed a head start when presented with semantically-constraining verbs (e.g., Read the book) compared to neutral verbs (e.g., Find the book). Children with weaker receptive language showed a smaller head start than children with stronger receptive language skills, suggesting continuity between typical development and ASD.

Sentence comprehension relies on the abilities to rapidly integrate different types of linguistic and non-linguistic information. The present study investigated whether Mandarin-speaking preschool children with autism spectrum disorder (ASD) are able to use verb information predictively to anticipate the upcoming linguistic input during real-time sentence comprehension. 26 five-year-olds with ASD, 25 typically developing (TD) five-year-olds and 24 TD four-year-olds were tested using the visual world eye-tracking paradigm. The results showed that the 5-year-olds with ASD, like their TD peers, exhibited verb-based anticipatory eye movements during real-time sentence comprehension. No difference was observed between the ASD and TD groups in the time course of their eye gaze patterns, indicating that Mandarin-speaking preschool children with ASD are able to use verb information as effectively and rapidly as TD peers to predict the upcoming linguistic input.
