Objective: To identify correlates of deliberate self-harm (DSH) in youth with autism and/or intellectual disability (ID).
Method: This retrospective longitudinal cohort analysis used claims data for youth ages 5 to 24 years continuously enrolled in Medicaid in a midwestern state for 6 months and diagnosed with autism and/or ID between 2010 and 2020 (N = 41,230). Cox proportional hazards regression examined associations between demographic and clinical variables and time to DSH for study cohorts with autism and/or ID.
Results: Autism was diagnosed in 34.3% of the sample, ID was diagnosed in 30.6%, and both autism and ID were diagnosed in 35.1%. Sample youth were predominantly male (73.4%) and had an internalizing (74.8%) or externalizing (62.1%) mental health condition. At least 1 DSH event was identified for 734 youths (2.6%) with autism and 686 youths (2.7%) with ID during follow-up. Increased risk of DSH was associated with older age; female sex; history of abuse or neglect; and co-occurring externalizing problems, internalizing problems, substance use, and thought problems for the autism cohort and ID cohort and with the presence of a chronic complex medical condition in the autism cohort. Risk of DSH was significantly lower for youth with moderate ID and youth eligible for Medicaid via disability and foster care.
Conclusion: Risk factors for DSH in youth with autism and ID are similar to those in neurotypical youth and include increasing age, trauma, mental health conditions, substance use, and female sex. Clinician and consumer education regarding suicide risk and its correlates in youth with autism and ID warrants study.

Autism is a neurodevelopmental condition associated with altered resting-state brain function. An increased excitation-inhibition ratio is discussed as a pathomechanism but in-vivo evidence of disturbed neurotransmission underlying functional alterations remains scarce. We compare local resting-state brain activity and neurotransmitter co-localizations between autism (N = 405, N = 395) and neurotypical controls (N = 473, N = 474) in two independent cohorts and correlate them with excitation-inhibition changes induced by glutamatergic (ketamine) and GABAergic (midazolam) medication.

Background: Autism spectrum disorder (ASD) and social communication disorder (SCD) are neurodevelopmental disorders characterized by deficits in social communication that hinder social adaptation, with limited pharmacological options for therapy owing to the absence of identified biomarkers. Individuals with ASD or SCD require lifelong interventions tailored to their development stages. However, most existing interventions primarily focus on early childhood, leaving adolescents relatively underserved.

In recent years, there has been a significant increase in minors with gender dysphoria (GD) seeking transition treatments, including puberty blockers and cross-sex hormones. The developing child's brain exhibits structural and functional differences in children with GD compared to cisgender children, particularly in areas where sex differences exist. Brain development during childhood and adolescence is strongly influenced by sex hormones.

The COVID-19 pandemic significantly worsened mental health (MH) challenges among young people. We aimed to assess changes in mental health-related outpatient care before and after the onset of the pandemic. In this nationwide cross-sectional study, we retrieved visits to general practitioners (GP) resulting in the coding of a MH disorder and/or the prescribing of any psychotropic medication for children aged 6 to 17 years, from January 1, 2016 to May 31, 2022 in France.

Objective: The goal of this study is to characterize health outcomes across 3 domains-overall well-being, behavioral health, and physical health-in a large sample of autistic and non-autistic children and adolescents in the Environmental influences on Child Health Outcomes (ECHO) program.
Method: First, we examined differences in health outcomes between autistic (N = 286) and non-autistic (N = 4,225) children and adolescents in the ECHO Program. Using a subsample of 1,809 participants (116 autistic participants) with complete outcome data, we conducted latent profile analyses (LPAs) to define profiles of health outcomes for autistic children and adolescents and for the combined sample of autistic and non-autistic participants.
