Accumulating evidence from neuroimaging studies has implicated widespread disruptions in brain connectivity in autism spectrum disorder (ASD), with altered connectivity patterns reported as early as infancy. However, it remains unexplored whether functional connectivity differences are evident prior to birth in the brain of fetuses who will later exhibit autistic traits in early childhood. In this study, we leveraged a longitudinal sample of 62 children with both quality-assured fetal brain resting-state MRI data and a parent-report measure of autistic traits at age 3 years. Enrichment analysis was employed to identify network pairs significantly correlated with autistic traits. Specificity analysis was conducted by additionally controlling for other childhood psychopathology. Our results demonstrated significant correlations between autistic traits and functional connectivity in the cingulate-left temporal and right prefrontal-left operculum network pairs in both the primary and specificity analyses. Visual network connectivity with prefrontal and opercular regions was also implicated. These network pairs demonstrated positive associations with autistic traits, indicating that stronger connectivity between these network pairs was associated with higher autistic traits. In contrast, weaker cerebellum-right operculum connectivity was associated with higher autistic traits, uniquely in the specificity analysis. This study provides the first in vivo evidence prospectively linking variation in functional network connectivity in the fetal brain to autistic traits in toddlerhood. These findings extend the current understanding of the prenatal brain origins of ASD and highlight the potential of fetal rs-fMRI as a tool to identify neural signatures related to social-emotional development and ASD likelihood.

BACKGROUND:Risky sexual behaviours (RSB) and attention deficit hyperactivity disorder (ADHD) are both major concerns among university students. However, their association remains insufficiently understood. This study aimed to evaluate the relationship between ADHD symptoms and a broad range of RSB in university students. METHODS:A total of 13 085 French students enrolled in the i-Share (Internet-based Students' Health Research Enterprise study (mean age: 20.6 years, SD=2.4) completed self-reported questionnaires assessing ADHD symptoms (Adult Self-Report Scale V.1.1), RSB, sociodemographic characteristics and alcohol and cannabis use. Logistic regression models were used to examine the cross-sectional associations between ADHD symptoms and RSB, adjusting for relevant confounders. RESULTS:A high level of ADHD symptoms was observed in 5.3% of students. In multivariate models, ADHD symptoms were associated with a wide range of RSB, including early first sexual intercourse (adjusted OR (aOR) 1.26; 95% CI 1.06 to 1.51), inconsistent condom use in the last 12 months (aOR 1.26; 95% CI 1.05 to 1.51), diagnosis of a sexually transmitted infection in the last 12 months (aOR 1.60; 95% CI 1.16 to 2.22) and having had multiple sexual partners in the last 12 months (adjusted incidence rate ratio 1.20; 95% CI 1.14 to 1.27). Among female students, ADHD symptoms were associated with lower current use of any form of contraception (aOR 0.59; 95% CI 0.48 to 0.71), and higher odds of having ever used emergency contraception (aOR 1.22; 95% CI 1.02 to 1.47), and having ever had an abortion (aOR 1.77; 95% CI 1.21 to 2.58). CONCLUSIONS:University students with a high level of ADHD symptoms are at increased risk of engaging in a wide range of RSB. Targeted preventive strategies may be particularly beneficial for this population.

BACKGROUND/UNASSIGNED:Sleep deprivation among young adults is a pervasive problem driven by high levels of stress, excessive screen time, disruptive school and living environments, irregular sleep habits, high academic demands, early school start times, and low rates of physical activity. Difficulties with emotion regulation, high rates of anxiety and depression, and poor academic performance are only a few of the struggles faced by sleep deprived young adults. Although sleep apps and wearables are increasingly popular, knowledge of positive sleep health without the proper tools to motivate and instill behavior change can contribute to anxiety and negative cognitions about sleep, which only further fuel the problem. METHODS/UNASSIGNED:In this report we describe a series of undergraduate university curricula, housed within a unique undergraduate department, designed to enhance not only knowledge of sleep, but also associated behavior changes that have been demonstrated to improve sleep, mood, and anxiety among university students. RESULTS/UNASSIGNED:Numerous courses within the Child and Adolescent Mental Health Studies (CAMS) department at New York University address sleep directly, teaching students about the science of sleep and how they can improve their own sleep to enhance overall wellbeing. Our work to date demonstrates that students find these courses desirable and impactful. CONCLUSION/UNASSIGNED:College courses present a unique opportunity to improve the health and wellbeing of young adults by teaching about sleep health. Undergraduate campuses may represent an underutilized locale from which to address population health.

INTRODUCTION/UNASSIGNED:Over recent decades, research has identified both overlapping and distinct characteristics, risk factors, and genetic as well as neurobiological correlates associated with Attention-Deficit/Hyperactivity Disorder (ADHD) and Autism Spectrum Disorder (ASD). This expanding body of evidence is increasingly informing the clinical management of individuals with comorbid ADHD and ASD. AREAS COVERED/UNASSIGNED:Based on a targeted PubMed search conducted up to March 24,2025,24.03.25, prioritizing meta-analyses or umbrella reviews over primary studies (whenever relevant), with terms encompassing autism, assessment, and treatment, this review addresses: 1) Shared and distinct phenotypic characteristics, neuropsychological features, and genetic and neuroimaging correlates of ADHD and ASD; 2) The assessment of individuals presenting with both ASD and ADHD symptoms; 3) Pharmacological and non-pharmacological strategies for the management for individuals with comorbid ASD and ADHD. EXPERT OPINION/UNASSIGNED:The comorbidity of ADHD and ASD should not be overlooked. Nevertheless, before diagnosing comorbid ASD and ADHD, clinicians should perform a thorough differential diagnosis, ensuring that ADHD symptoms are not better explained by ASD. Regarding treatment, further research is warranted to develop personalized approaches, support long-term management strategies, and evaluate real-world outcomes such as quality of life, which are often underrepresented in clinical trials.

INTRODUCTION/BACKGROUND:Females with disabilities have greater preconception health risks and adverse perinatal outcomes than those without disabilities. Characterization of reproductive health care utilization among females with disabilities in the United States is limited. We examined health care receipt before, during, and after pregnancy by extent of disability among U.S. females with recent live births. METHODS:This cross-sectional study used Pregnancy Risk Assessment Monitoring System data (collected 2018-2020 and analyzed in 2025) from 24 states that included the Washington Group Short Set of Questions on Disability. Participants self-reported health care visits in the year prior to pregnancy; receipt and timing of prenatal care; and receipt of a postpartum checkup. Disability was assessed as extent of difficulty (none, some, and a lot of difficulty). Associations between extent of disability and health care utilization were estimated using multivariable modified Poisson regression (adjusted prevalence ratios, aPR, and 95% confidence intervals, CI). RESULTS:trimester initiation of prenatal care, but they had a 171% (aPR=2.71, 95% CI: 1.49-4.94) and 63% (aPR=1.63, 95% CI: 1.40-1.91) higher prevalence of not having any prenatal care and not having a postpartum checkup, respectively, than females with no difficulty. CONCLUSIONS:Females with some and a lot of difficulty reported lower receipt of reproductive, prenatal, and postpartum care than those with no difficulty. Strategies are needed to establish and coordinate comprehensive reproductive health care among females with disabilities.

Individuals with Alzheimer's disease (AD) have an increased incidence of seizures, which worsen cognitive decline. Using a transgenic mouse model of AD neuropathology that exhibits spontaneous seizures, we previously found that seizure activity stimulates and accelerates depletion of the hippocampal neural stem cell (NSC) pool, which was associated with deficits in neurogenesis-dependent spatial discrimination. However, the precise molecular mechanisms that drive seizure-induced activation and depletion of NSCs are unclear. Here, using mice of both sexes, we performed RNA-sequencing on the hippocampal dentate gyrus and identified differentially-expressed regulators of neurogenesis in the Wnt signaling pathway that regulates many aspects of cell proliferation. We found that the expression of sFRP3, a Wnt signaling inhibitor, is altered in a seizure-dependent manner and might be regulated by ΔFosB, a seizure-induced transcription factor. Increasing sFRP3 expression prevented NSC depletion and improved spatial discrimination, suggesting that the loss of sFRP3 might mediate seizure-driven impairment in cognition in AD model mice, and perhaps also in AD.Significance statement There is increased incidence of seizures in individuals with Alzheimer's disease (AD), but it is unclear how seizures contribute to cognitive decline. Here, we uncover a molecular mechanism by which seizures in AD induce expression of a long-lasting transcription factor in the hippocampal dentate gyrus that suppresses expression of sFRP3, an inhibitor of neural stem cell division, accelerating the depletion of a finite pool of neural stem cells and dysregulating adult hippocampal neurogenesis. We found that restoring sFRP3 expression prevents accelerated use and depletion of neural stem cells and improves performance in an adult neurogenesis-dependent cognitive task. Our findings have implications for AD, epilepsy, and other neurological disorders that are accompanied by seizures.

Autism and attention-deficit hyperactivity disorder (ADHD) are among the most common neurodivergent neurotypes worldwide. Epidemiological evidence shows that sleep and circadian disturbances, such as difficulty initiating and maintaining sleep, and delayed sleep-wake phase, are highly prevalent in autistic children, children with ADHD, and those with both neurotypes. Despite scientific advancements, a comprehensive framework integrating sleep and circadian mechanisms with targeted interventions for autism and ADHD remains underdeveloped. In this Review we examine sleep and circadian rhythm differences in autistic children and adolescents, and in those with ADHD or both neurotypes, focusing on the underlying biological mechanisms. We discuss recent advances in the genetic and molecular links between sleep, circadian rhythms, and neuroplasticity, alongside the influence of these systems on physiology and therapeutic strategies. Both pharmacological and non-pharmacological interventions are considered, with an emphasis on the need for an integrated support model that accounts for the dynamic interplay between sleep and circadian rhythms in these populations. We identify key gaps in the current evidence base, particularly in relation to non-pharmacological interventions, and outline future research directions. Although most randomised controlled trials in children and adolescents have focused on behavioural sleep interventions, we also discuss emerging findings from trials using alternative approaches, such as targeted light therapy in adults, with implications for paediatric populations. Finally, we emphasise the importance of incorporating the perspectives of autistic children and adolescents and those with ADHD, as well as their parents and caregivers, into research designs.

OBJECTIVE/UNASSIGNED:To examine pharmacotherapy and psychotherapy treatment recommendations among different races and socioeconomic groups of young children. A secondary objective evaluated whether changes in the 2007 American Academy of Child and Adolescent Psychiatry (AACAP) guidelines for attention-deficit/hyperactivity disorder (ADHD) treatment affected community prescribing practices. Hypotheses were that non-White children would be less likely to have psychotherapeutic treatments recommended for mental health issues and children with lower socioeconomic status index scores would be less likely to receive a psychotropic medication prescription. METHOD/UNASSIGNED:test and logistic regression models. RESULTS/UNASSIGNED:= .03). CONCLUSION/UNASSIGNED:Children's socioeconomic status, race/ethnicity, and insurance did not affect treatment recommendations of clinicians. However, children whose first prescription of psychotropic medication was from a primary care physician or pediatrician were less likely to have a recommendation for psychotherapy compared with children who were seen by psychiatrists. DIVERSITY & INCLUSION STATEMENT/UNASSIGNED:One or more of the authors of this paper self-identifies as a member of one or more historically underrepresented racial and/or ethnic groups in science. One or more of the authors of this paper self-identifies as a member of one or more historically underrepresented sexual and/or gender groups in science. We actively worked to promote sex and gender balance in our author group.

The use of complementary, alternative and integrative medicine (CAIM) is highly prevalent among autistic individuals, with up to 90% reporting having used CAIM at least once in their lifetime. However, the evidence base for the effects of CAIM for autism remains uncertain. Here, to fill this gap, we conducted an umbrella review of meta-analyses exploring the effects of CAIM in autism across the lifespan and developed a web platform to disseminate the generated results. Five databases were searched (up to 31 December 2023) for systematic reviews with meta-analyses exploring the effects of CAIM in autism. Independent pairs of investigators identified eligible papers and extracted relevant data. Included meta-analyses were reestimated using a consistent statistical approach, and their methodological quality was assessed with AMSTAR-2. The certainty of evidence generated by each meta-analysis was appraised using an algorithmic version of the GRADE framework. This process led to the identification of 53 meta-analytic reports, enabling us to conduct 248 meta-analyses exploring the effects of 19 CAIMs in autism. We found no high-quality evidence to support the efficacy of any CAIM for core or associated symptoms of autism. Although several CAIMs showed promising results, they were supported by very low-quality evidence. The safety of CAIMs has rarely been evaluated, making it a crucial area for future research. To support evidence-based consideration of CAIM interventions for autism, we developed an interactive platform that facilitates access to and interpretation of the present results ( https://ebiact-database.com ).
