BACKGROUND: Racial/ethnic disparities in access to diagnostic services are pervasive for autistic children. However, a few studies have examined racial/ethnic health disparities among autistic adults, who commonly experience higher rates of health conditions than non-autistic adults. We aimed at examining the intersection of autism and race/ethnicity in association with psychiatric and medical diagnoses. METHODS: The study population included adult members of Kaiser Permanente Northern California enrolled from 2008 to 2012. We ascertained 1507 adults who had an autism diagnosis documented in their electronic medical records. We sampled a matched control group of adults without an autism diagnosis (N = 15,070) at a 10:1 ratio. Our sample was 46% White, 17% Hispanic, 16% Asian, 7% Black, and 14% other race/ethnicity. We compared health diagnoses (a) between autistic and non-autistic adults within strata of race/ethnicity and (b) across race/ethnicity within strata of autistic and non-autistic adults. Lastly, we examined the interaction between autism and race/ethnicity on both multiplicative and additive scales. RESULTS: Autistic adults were more likely to be diagnosed with most medical and psychiatric conditions compared with their non-autistic counterparts of the same race/ethnicity. Among autistic adults, Black, Hispanic, and Asian adults were less likely to be diagnosed with psychiatric conditions and Black and Hispanic autistic adults were more likely to be diagnosed with obesity than their White counterparts. In interaction models, we found that adults who were Black and autistic were disproportionately less likely to be diagnosed with psychiatric conditions and autoimmune disease and more likely to be diagnosed with hypertension than expected. CONCLUSION: Health vulnerabilities may be compounded at the intersection of autism and race/ethnicity. Future research should continue to apply an intersectional lens toward understanding and addressing these disparities. Our findings likely underestimate the health disparities that exist in uninsured autistic adults and those living in other parts of the United States. WHY IS THIS AN IMPORTANT ISSUE? Very few studies have looked at how the combination of a person’s autistic and racial/ethnic identities affects their health in adulthood. Dual experiences of ableism and structural racism may have a larger negative effect on the health of autistic people of color than either one experience alone. It is important to identify potential health disparities so that they can be addressed. WHAT IS THE PURPOSE OF THIS STUDY? We wanted to understand whether autistic adults of color were more likely to be diagnosed with medical and psychiatric conditions than non-autistic and/or White peers. WHAT DID THE RESEARCHERS DO? We studied a diverse group of 1507 autistic adults and 15,070 non-autistic adults who all received health care from the same large, health plan in California. We examined electronic health records to determine whether diagnoses of health conditions differed by autism status and race/ethnicity. We then looked at whether autistic people of color were disproportionately diagnosed with these conditions compared with other groups. WHAT WERE THE RESULTS OF THE STUDY? Within every racial/ethnic group, autistic adults were more likely than non-autistic adults to be diagnosed with most medical and psychiatric conditions. Among the autistic group, Black, Hispanic, and Asian adults were less likely to be diagnosed with psychiatric conditions compared with White adults. We saw similar differences in psychiatric diagnoses by race/ethnicity among non-autistic adults. Further, the diagnostic patterns among adults who were autistic and Black suggested that this group may experience unique difficulties receiving mental health and autoimmune diagnoses. They also may be at a higher risk of hypertension. WHAT DO THESE FINDINGS ADD TO WHAT WAS ALREADY KNOWN? Previous studies have found racial/ethnic disparities in both mental health and access to health care among autistic children. This study suggests that racial/ethnic disparities, especially in mental health care, may also exist among autistic adults. WHAT ARE POTENTIAL WEAKNESSES IN THE STUDY? As a broad social label, race/ethnicity does not tell us much about people’s lived experiences. Future studies should replace race/ethnicity with more useful measures of our social environment, including economic opportunity and experiences of structural racism. In addition, health records may imperfectly represent the actual occurrence of health conditions. For example, we cannot tell from this study whether autistic people of color actually experience fewer psychiatric problems, are less likely to visit the doctor, or are more likely to have their problems missed by doctors. Lastly, because our findings are from an insured population, we have likely underestimated the health disparities that exist among autistic adults who do not have consistent insurance coverage or health care access. HOW WILL THESE FINDINGS HELP AUTISTIC ADULTS NOW OR IN THE FUTURE? We hope this study highlights the need for greater attention to the unique health risks at the intersection of autism and race/ethnicity in adults. Through more research and advocacy, we can increase awareness and understanding of these potential health disparities. This will lead to changes that promote more equal access to health care and greater well-being among autistic people of color. eng.

BACKGROUND: Autism spectrum disorder (ASD) is mainly characterized by deficits in social interaction and communication and repetitive behaviors. Known causes of ASD are mutations of certain risk genes like the postsynaptic protein SHANK3 and environmental factors including prenatal infections. METHODS: To analyze the gene-environment interplay in ASD, we combined the Shank3Δ11-/- ASD mouse model with maternal immune activation (MIA) via an intraperitoneal injection of polyinosinic/polycytidylic acid (Poly I:C) on gestational day 12.5. The offspring of the injected dams was further analyzed for autistic-like behaviors and comorbidities followed by biochemical experiments with a focus on synaptic analysis. RESULTS: We show that the two-hit mice exhibit excessive grooming and deficits in social behavior more prominently than the Shank3Δ11-/- mice. Interestingly, these behavioral changes were accompanied by an unexpected upregulation of postsynaptic density (PSD) proteins at excitatory synapses in striatum, hippocampus and prefrontal cortex. LIMITATIONS: We found several PSD proteins to be increased in the two-hit mice; however, we can only speculate about possible pathways behind the worsening of the autistic phenotype in those mice. CONCLUSIONS: With this study, we demonstrate that there is an interplay between genetic susceptibility and environmental factors defining the severity of ASD symptoms. Moreover, we show that a general misbalance of PSD proteins at excitatory synapses is linked to ASD symptoms, making this two-hit model a promising tool for the investigation of the complex pathophysiology of neurodevelopmental disorders.

What is already known about the topic?Autistic youths increasingly enter universities. We know from existing research that autistic students are at risk of dropping out or studying delays. Using machine learning and historical information of students, researchers can predict the academic success of bachelor students. However, we know little about what kind of information can predict whether autistic students will succeed in their studies and how accurate these predictions will be.What does this article add?In this research, we developed predictive models for the academic success of 101 autistic bachelor students. We compared these models to 2,465 students with other health conditions and 25,077 students without health conditions. The research showed that the academic success of autistic students was predictable. Moreover, these predictions were more precise than predictions of the success of students without autism.For the success of the first bachelor year, concerns with aptitude and study choice were the most important predictors. Participation in pre-education and delays at the beginning of autistic students’ studies were the most influential predictors for second-year success and delays in the second and final year of their bachelor’s program. In addition, academic performance in high school was the strongest predictor for degree completion in 3 years.Implications for practice, research, or policyThese insights can enable universities to develop tailored support for autistic students. Using early warning signals from administrative data, institutions can lower dropout risk and increase degree completion for autistic students.

BACKGROUND: Parents of youth with intellectual and developmental disabilities (IDD) may have a higher prevalence of overweight and obesity and poorer weight management behaviors compared to the general population. OBJECTIVE: To describe the prevalence of overweight/obesity and related socioeconomic and lifestyle factors including diet quality, physical activity, and reported health habits in parents of youth with IDD. METHODS: We assessed: BMI (kg/m(2)), moderate-to-vigorous physical activity (MVPA), fruit and vegetable intake (FVI), parental diet and physical activity habits, and socioeconomic characteristics. Associations of BMI on MVPA and FVI were assessed with Spearman’s correlation; differences in BMI by parental diet and physical activity habits were assessed with Kruskall-Wallis tests; and the relationships of BMI to household income, race, and education were assessed with Kendall Tau-b and Mann Whitney U tests. RESULTS: Data was obtained from 110 parents (97.3% female) who were study partners for their adolescents/young adults with IDD participating in a weight loss clinical trial. Approximately 81% of parents were overweight or obese (25.7% overweight, 55.1% obese), with 46.3% and 20% meeting the recommended U.S. guidelines for MVPA and FVI, respectively. Higher FVI and higher income were significantly associated with lower parent BMI. BMI was significantly lower in parents who reported to be physically active and choose healthy food. CONCLUSION: We observed a high prevalence of overweight/obesity, low FVI and low levels of MVPA in parents of adolescents with IDD. These observations suggest that interventions designed to address these factors have the potential to improve the health and wellbeing of both parents and adolescents with IDD. CLINICAL TRIALS NUMBER: NCT02561754.

Research shows that parents of autistic children, on average, are stressed; however, there is likely an array of factors that characterize the parenting experience in the context of autism other than stress. Understanding the diversity in the parenting experiences of both mothers and fathers of autistic children is important in the development of family-based intervention. A total of 188 co-habiting couples with an autistic child described their parenting experiences using a series of questionnaires examining their feelings of stress, parenting competence, and parenting attitudes and behaviors. We then sorted responses into profiles-three for mothers and four for fathers. We found that children of parents who reported the least amount of stress, highest feeling of competence, and use of responsive and directive parenting strategies (the Adaptive profile) had children with the least severe behavioral problems and autism symptoms. It was not necessary for both parents to be in the Adaptive category for child emotional and behavioral problems to less severe. We found that children did just as well when one parent was Adaptive compared with when both parents fell into this category.

The Utility of Natural Language Samples for Assessing Communication and Language in Infants Referred with Early Signs of Autism. Research on child and adolescent psychopathology. 2023.
Natural Language Sampling (NLS) offers clear potential for communication and language assessment, where other data might be difficult to interpret. We leveraged existing primary data for 18-month-olds showing early signs of autism, to examine the reliability and concurrent construct validity of NLS-derived measures coded from video-of child language, parent linguistic input, and dyadic balance of communicative interaction-against standardised assessment scores. Using Systematic Analysis of Language Transcripts (SALT) software and coding conventions, masked coders achieved good-to-excellent inter-rater agreement across all measures. Associations across concurrent measures of analogous constructs suggested strong validity of NLS applied to 6-min video clips. NLS offers benefits of feasibility and adaptability for validly quantifying emerging skills, and potential for standardisation for clinical use and rigorous research design.

The current study investigated the structural validity and internal consistency of the Strengths and Stressors (SSF) questionnaire. The SSF is used in Swedish habilitation services to measure the positive and negative consequences that the fostering of a child with a developmental disability can have on family functioning in six domains: parent’s feelings and attitudes, social life, family finances, relationship to the other parent, siblings, and professional support. The proposed six-factor model was tested with confirmatory factor analysis with data collected from 291 parents of children with developmental disabilities. The six-factor model had an acceptable fit according to most fit indices, but two items were non-significant. Overall, the internal consistency was acceptable or good. The SSF, with the proposed six-factor solution, can be a useful tool when assessing parental perspectives on the impacts of having a child with a developmental disability in clinical settings and research.

Prior studies show that neurofeedback training (NFT) of mu rhythms improves behavior and EEG mu rhythm suppression during action observation in children with autism spectrum disorder (ASD). However, intellectually impaired persons were excluded because of their behavioral challenges. We aimed to determine if intellectually impaired children with ASD, who were behaviorally prepared to take part in a mu-NFT study using conditioned auditory reinforcers, would show improvements in symptoms and mu suppression following mu-NFT. Seven children with ASD (ages 6-8; mean IQ 70.6 ± 7.5) successfully took part in mu-NFT. Four cases demonstrated positive learning trends (hit rates) during mu-NFT (learners), and three cases did not (non-learners). Artifact-creating behaviors were present during tests of mu suppression for all cases, but were more frequent in non-learners. Following NFT, learners showed behavioral improvements and were more likely to show evidence of a short-term increase in mu suppression relative to non-learners who showed little to no EEG or behavior improvements. Results support mu-NFT’s application in some children who otherwise may not have been able to take part without enhanced behavioral preparations. Children who have more limitations in demonstrating learning during NFT, or in providing data with relatively low artifact during task-dependent EEG tests, may have less chance of benefiting from mu-NFT. Improving the identification of ideal mu-NFT candidates, mu-NFT learning rates, source analyses, EEG outcome task performance, population-specific artifact-rejection methods, and the theoretical bases of NFT protocols, could aid future BCI-based, neurorehabilitation efforts.

An earlier diagnosis of autism spectrum disorder might lead to earlier intervention. However, people living in Latin American and Caribbean countries do not have much knowledge about autism spectrum disorder symptoms. It has been suggested that the older a child is when diagnosed, the fewer opportunities he or she will have to receive services. We asked 2520 caregivers of autistic children in six different Latin America and Caribbean Countries, the child’s age when they noticed some developmental delays and their child’s age when they received their first autism spectrum disorder diagnosis. Results indicate that, on average, caregivers were concerned about their child’s development by 22 months of age; however, the diagnosis was received when the child was 46 months of age. In addition, older children with better language abilities and public health coverage (opposed to private health coverage) were diagnosed later. On the contrary, children with other medical problems and more severe behaviors received an earlier diagnosis. In our study, children were diagnosed around the time they entered formal schooling, delaying the access to early intervention programs. In summary, the characteristics of the autistic person and the type of health coverage influence the age of diagnosis in children living in Latin America and Caribbean Countries.

BACKGROUND: Cystic Fibrosis (CF) and autism spectrum disorder (ASD) are life-long conditions with intense treatment burdens for patients and families. Patients with a concurrent diagnosis (CF-ASD) experience unique obstacles to CF care. This study describes the experiences of our multidisciplinary CF team in caring for patients with CF-ASD and provides insight into provider and parental perspectives on clinical management. METHODS: This is a three-part qualitative study involving 1) retrospective chart review of patients with CF-ASD, 2) surveys with multi-disciplinary care team members, and 3) semi-structured interviews with caregivers of patients with CF-ASD. Challenges in clinical management of this specific cohort were compiled using data from chart review and care team surveys. Strategies to address these concerns were identified and rated by individual families based on relevance and practicality. RESULTS: Within our CF center, 12 patients have an official diagnosis of ASD. Median age of patients with CF-ASD was 8.5 years (range 3-20 years), 67% were male, and 83% were on highly effective modulator therapy. Clinical barriers included sensory processing issues, environmental overstimulation, intolerance to procedures and to disrupted routines. Potentially impactful strategies include patient-specific coping plans, guided behavioral interventions, parental advocacy, and improved communication between the family and multidisciplinary team. CONCLUSION: Children with CF-ASD face extraordinary challenges beyond the experience of neurotypical children with CF. Increased awareness of this complex dual diagnosis will help providers be sensitive to the unique needs of these patients, help build consistent and trustworthy relationships with their families and deliver effective clinical care despite limitations.

12. Rifai OM, Fletcher-Watson S, Jiménez-Sánchez L, Crompton CJ. Investigating Markers of Rapport in Autistic and Nonautistic Interactions. Autism in adulthood : challenges and management. 2022; 4(1): 3-11.
BACKGROUND: Autism is considered to entail a social impairment whereby autistic people experience difficulty interpreting others’ mental states. However, recent research has shown that nonautistic people also have difficulty understanding the mental states of autistic people. This mismatch of understanding may explain lower rapport in interactions between autistic and nonautistic people. As mental states can be expressed externally through socially normed signals, it is important to investigate the role of such signals in autistic, nonautistic, and mixed interactions. This study explores variability in two social signals between autistic, nonautistic, and mixed interactions, and how their use may affect rapport within interactions. METHODS: Videos from a previous study of autistic, nonautistic, and mixed pair interactions in a diffusion chain context in which participants were aware of others’ diagnostic status were video coded for mutual gaze and backchanneling as candidate indicators of interactional rapport. RESULTS: Although use of mutual gaze and backchanneling was lower in mixed pairs than in nonautistic pairs, corresponding to lower ratings of interactional rapport, less backchanneling in autistic pairs of both nonverbal and verbal subtypes corresponded to higher ratings of rapport. CONCLUSIONS: We observed differences in the use of candidate rapport markers between autistic, mixed, and nonautistic interactions, which did not map onto patterns of rapport scores, suggesting differences in reliance on these cues between autistic and nonautistic people. These results suggest that visible markers of rapport may vary by neurotype or pairing and give clues to inform future investigations of autistic interaction. WHY IS THIS AN IMPORTANT ISSUE? When someone is autistic, society generally assumes they have difficulty interacting with others. Social difficulties between autistic and nonautistic people are thought to be due to the autistic person not being able to interact using nonautistic social behaviors. This belief can lead to many autistic people feeling alienated. However, recent research supports what autistic people have been saying for a long time: that autistic people are capable of having successful and rewarding interactions with other autistic people. This suggests that social difficulties between autistic and nonautistic people may be due to a mismatch in social norms leading to difficulty for both people, not just the autistic person. WHAT WAS THE PURPOSE OF THIS STUDY? In this study, we wanted to investigate whether certain social signals are used differently between autistic and nonautistic people. We also questioned whether using these signals helped or hurt the interaction depending on who was involved. WHAT DID THE RESEARCHERS DO? We recorded people passing a story down a chain of people, like the game telephone, to see how they interacted with each other. Afterward, people wrote down scores for how much they enjoyed their interaction. We focused on two parts of the interaction: how much people were looking at each other and when they made short verbal responses such as “mhm” to show they were listening (backchanneling). We watched the recordings back and analyzed how long or how many times these actions were occurring. WHAT WERE THE RESULTS OF THE STUDY? We found that when one autistic and one nonautistic person were interacting, they looked at each other and backchanneled less than two nonautistic people. This seemed to be linked with a less enjoyable interaction for them. However, backchanneling seemed to matter less in interactions between two autistic people. They backchanneled less while still having enjoyable interactions. WHAT DO THESE FINDINGS ADD TO WHAT WAS ALREADY KNOWN? Research has previously suggested that different social norms exist between autistic and nonautistic people. This study shows specific examples of this and how they may affect the interaction in a natural setting. WHAT ARE POTENTIAL WEAKNESSES IN THE STUDY? This study has some weaknesses. For example, we measured when people looked at each other’s faces rather than eye contact specifically, which can only be done with an eye tracker. Also, the people in the study knew whether the person they were talking to was autistic. This can be similar to normal life, as people do sometimes know this, although we would also be interested to see what the effect of not knowing would be. HOW WILL THESE FINDINGS HELP AUTISTIC ADULTS NOW OR IN THE FUTURE? This line of research has important implications for how autistic people can be supported in society. Not only will understanding of social differences between autistic and nonautistic people help the way autistic people are perceived, but it will also help nonautistic people better understand and support the autistic people in their lives. eng.

BACKGROUND: Autistic adults have an elevated risk of many health problems compared with the general population, making health care access extra critical. Unfortunately, autistic people often find health care settings quite aversive, and many medical providers report feeling unsure about how to interact with autistic patients. We aimed at characterizing specific challenges regarding sensory experiences and communicative barriers in health care settings. METHODS: We recruited adults to complete an anonymous online questionnaire on the topic of improving health care experiences for everyone. The questions covered demographics, sensory experiences in medical settings, and communication with health care providers. We quantified the associations between autism diagnosis and experiences of sensory discomfort and communication barriers in health care settings. We also did a qualitative analysis of text responses to questions on how to improve sensory environments and communication with providers. RESULTS: Swedish adults (62 autistic and 36 nonautistic) participated in the study. The cohort was well educated, and autistic participants received their autism diagnosis late in life (median age 36 years, range 13-57). Compared with nonautistic participants, autistic participants reported greater discomfort with background sound levels in health care settings and felt more misunderstood by health care providers. Thematic analyses showed that auditory stimuli and proximity to other people were particularly bothersome for autistic participants, causing stress or avoidance and affecting the ability to interact with providers. Providers contributed to communication barriers by failing to recognize the need for individualized information, especially when respondents’ difficulties were not visible or taken seriously. Participants requested greater clarity and supplementary written information. Providers also misunderstood autistic adults’ body language or eye contact patterns, as they interpreted their clients through the lens of neurotypical expectations. CONCLUSIONS: Our results extend previous research by emphasizing sensory aspects of health care settings and suggesting specific and reasonable adaptations. The results also highlight how the provider’s implicit expectations of nonverbal communication caused misinterpretations of autistic people who were socially skilled but did not use typical body language. Based on the data, we suggest specific adaptations, many of which may also benefit nonautistic people. WHY WAS THIS STUDY DONE? Health care needs of autistic adults are often unmet. This may contribute to poorer health outcomes in autistic compared with nonautistic adults. Autistic differences may not be obvious in this group because of behavioral compensation strategies. Health care providers may underestimate the support needs of autistic adults, leading to decreased quality of care. By analyzing autistic adults’ own experiences, we may better understand barriers to effective health care. WHAT WAS THE PURPOSE OF THIS STUDY? We aimed at identifying patterns of sensory and communicative experiences that autistic adults find problematic in health care settings. WHAT DID THE RESEARCHERS DO? In an online questionnaire, we asked autistic and nonautistic adults how they experienced various medical settings. We focused on specific sensory inputs, such as light levels and background sounds, in waiting rooms and other medical contexts. We also asked questions about communication between patients and providers. Finally, we did a qualitative analysis on free-text responses about sensory environments for both groups, and about communication for the autistic group. WHAT WERE THE RESULTS OF THE STUDY? Ninety-eight people (62 autistic) participated. Most of the cohort was female or gender-diverse, middle-age, and well educated. Autistic participants identified auditory inputs as one of the greatest stressors in medical settings. They discussed the impact of light levels and other people’s presence on their energy levels and ability to communicate. Health care providers often misunderstood their autistic patients, leading to a failure in transferring medical information. Participants described how providers underestimated their needs, even when they were aware of the autism diagnosis. Participants wanted to get information delivered at a slower pace and with a greater amount of detail, to be better able to process medical or procedural information. WHAT DO THESE FINDINGS ADD TO WHAT WAS ALREADY KNOWN? The study contributes with information on specific sensory challenges and suggests that auditory noise is particularly problematic for autistic people. On the topic of communication, the findings point to a “double empathy” problem, whereby the provider’s own limitations contribute significantly to communication barriers. This was apparent in accounts of nonverbal communication, where the provider’s expectations of neurotypical body language caused misunderstandings that were difficult to overcome. WHAT ARE THE POTENTIAL WEAKNESSES IN THE STUDY? The sample was small and comprised an ethnically narrow demographic group. Thus, the results are not generalizable to other autistic populations, such as minimally verbal adults. We also did not measure health status beyond diagnosed conditions. HOW WILL THESE FINDINGS HELP AUTISTIC ADULTS NOW OR IN THE FUTURE? The consequences of sensory and communicative barriers may go entirely unnoticed when autistic differences are not visible. Unsuccessful interactions with the health care system may have enormous effects on the health and quality of life of autistic people. Therefore, educators and providers may use the insightful information provided by autistic participants in this study to inform decisions on staff training or design of sensory environments. eng.

Autism spectrum disorder (ASD) is characterized by social communicative disturbance. Social communication requires rapid processing and accurate cognition regarding others’ emotional expressions. Previous electrophysiological studies have attempted to elucidate the processes underlying atypical face-specific N170 responses to emotional faces in ASD. The present study explored subliminal affective priming effects (SAPEs) on the N170 response and time-frequency analysis of intertrial phase coherence (ITPC) for the N170 in ASD. Fifteen participants [seven participants with ASD and eight typically developing (TD) controls] were recruited for the experiment. Event-related potentials were recorded with a 128-channel electroencephalography device while participants performed an emotional face judgment task. The results revealed enhanced N170 amplitude for supraliminal target-face stimuli when they were preceded by subliminal fearful-face stimuli, in both the ASD and TD groups. Interestingly, TD participants exhibited higher alpha-ITPC in the subliminal fearful-face priming condition in the right face-specific area in the N170 time window. In contrast, there were no significant differences in ITPC in any frequency bands between the subliminal fearful and neutral priming conditions in the ASD group. Asynchronous phase-locking neural activities in the face-specific area may underlie impaired nonconscious face processing in ASD, despite the presence of common features of SAPEs for the N170 component in both the ASD and TD groups.

OBJECTIVE: To identify clinical features that could distinguish children presenting with autistic-like features and a history of severe early maltreatment from children with idiopathic autism spectrum disorders (ASDs). DESIGN: Matched-comparison study. SETTING: Great Ormond Street Hospital, UK. PARTICIPANTS: 46 children with a history of early maltreatment, mean (SD) age 10.6 (3.3) years and 47 children with an ASD, mean (SD) age 10.4 (2.9) years. MAIN OUTCOME MEASURES: A range of standardised interview and observational measures that are designed to quantify autistic traits. Caregiver and teacher reports were obtained on broader aspects of behavioural and emotional adjustment. RESULTS: Both groups had normal range IQ and were predominantly male. On the basis of autistic traits alone, caregiver interview and structured observation concurred that over 60% of the formerly maltreated children met criteria for an ASD. Autistic symptom profiles were very similar in both groups, although children with idiopathic ASD had significantly more marked repetitive and stereotyped behaviours. Teacher and caregiver reports indicated that children from both groups had an increased and broadly similar prevalence of emotional and behavioural disorders. CONCLUSION: Children presenting with a history of early maltreatment, who show autistic traits of behaviour, have a high risk of meeting diagnostic criteria for ASD. Their symptom profiles are virtually indistinguishable from children with idiopathic autism.

PURPOSE: To identify gene signatures that are shared by autism spectrum disorder (ASD) and epilepsy (EP) and explore the potential molecular mechanism of the two diseases using WGCNA analysis. Additionally, to verify the effects of the shared molecular mechanism on ADHD, which is another neurological comorbidity. METHODS: We screened the crosstalk genes between ASD and EP based on WGCNA and differential expression analysis from GEO and DisGeNET database and analyzed the function of the genes’ enrichment by GO and KEGG analyses. Then, with combination of multiple datasets and multiple bioinformatic analysis methods, the shared gene signatures were identified. Moreover, we explored whether the shared gene signature had influence on the other neurological disorder like ADHD by analyzing the difference of the relative genes’ expression based on bioinformatic analysis and molecular experiment. RESULTS: By comprehensive bioinformatic analysis for multiple datasets, we found that abnormal immune response and abnormal lipid metabolic pathway played important roles in coincidence of ASD and EP. Base on the results of WGCNA, we got the hub genes in ASD and EP. In attention deficit and hyperactivity disorder (ADHD) animal model, we also found a significant difference of gene expression related to sulfatide metabolism, indicating that the abnormal sphingolipid metabolism was common in multiple neurological disorders. CONCLUSION: This study reveals shared gene signatures between ASD and EP and identifies abnormal sphingolipid metabolism as an important participant in the development of ASD, EP, and ADHD.

This study aims to explore the effects of zinc water on autism-like behavior, convulsion threshold, and neurogenesis in ASD model animals. This study used the young BTBR ASD mouse model to explore the effect of a 6-week zinc water supplementation on ASD-like behaviors such as repetitive behavior and social communication disorder, seizure threshold, and the correlation with excitability regulation. The mice were divided into four groups of normal controls (B6) and models (BTBR) who did and did not receive zinc supplementation in water (B6, B6 + zinc, BTBR, and BTBR + zinc). For morphological changes in the hippocampus, we selected two indicators: hippocampal mossy fiber sprouting and neurogenesis. ASD-like behavior testing, seizure threshold determination, Timm staining, and neurogenesis-related assays-represented by Ki67 and DCX-were performed after 6 weeks of zinc supplementation. Our results show that zinc water can prevent autism-like behavior, reduce susceptibility to convulsions, and increase the proliferation of hippocampal progenitor cells in BTBR mice but has less effect on mossy fiber sprouting and neural progenitor cell differentiation. Zinc water reduces autism-like behavior in a partially inherited autism model mice-BTBR-which may be associated with hippocampal neural precursor cell proliferation and reversed hyperexcitability.
