Our objective was to use longitudinal Medicaid and Medicare data to describe the epidemiology of ADRD in publicly insured autistic adults. We used all claims and encounters from 2011 to 2019 to identify autism and ADRD. We calculated prevalence, incidence, age at onset, and created survival curves. There were 90,229 autistic adults ≥ 30 years of age and enrolled for at least 1 year in Medicaid and/or Medicare and 267 ADRD cases. Prevalence of ADRD was 2.09% (95% CI: 1.99%, 2.20%) in 2011 and 8.11% (95% CI: 7.92%, 8.30%) in 2019. Mean age at ADRD onset was 59.3 years (SD: 14.2). Mean age among men was 58.3 years (SD: 13.8) and 61.0 years among females. Incidence of ADRD was higher in autistic adults with intellectual disability with no difference by sex. ADRD is a prevalent condition in middle- and older-aged adults identified with autism in the Medicaid and Medicare system.

We examined associations between prenatal alcohol exposure during the first trimester (PAE-FT) and early learning ability, behavioral problems, and severity of autistic traits in preschool-aged children in a large multi-site case–control study, the Study to Explore Early Development. Children were classified as ASD (<i>n</i> = 1237) or population comparison without ASD (POP, <i>n</i> = 1334) after an in-person assessment covering cognitive abilities and detailed autistic traits. Mothers completed questionnaires on their child's behavior and autism-related traits, as well as their alcohol use during pregnancy. Of children in the ASD and POP groups, 18.5% and 20.2%, respectively, were exposed to PAE-FT. Exposure to 3 or more alcoholic drinks per week was associated with increased externalizing behaviors (i.e., attention deficits and aggressive behaviors) in children in both the ASD and POP groups, and with exacerbated social communication and interaction deficits in children with ASD only. First trimester exposure to 1–2 alcoholic drinks per week was associated with early learning delays for children in the ASD group, but not the POP group. As expected, our findings suggest that PAE-FT is associated with adverse behavioral development of children regardless of ASD status. However, PAE-FT may exacerbate autism-specific developmental problems and learning difficulties in children with ASD.

Here we directly compare this group with a community sample of early diagnosed autistic individuals (community autism; CA). First, we characterized the QA autism symptom profile (61.5% females) by calculating which of the 32 Social Communication Questionnaire (SCQ) items were statistically more common in the QA group than in a control group of 52 non-deprived UK adoptees (UK Control, 34.6% females) at ages 11, 15, and/or 23 years of age. The latent structure of these QA-characteristic items was explored using confirmatory factor analyses. Second, we compared the QA symptom profiles with CA profiles using a sample from the QUEST study (Salazar et al. 2015). To do this, we identified two QUEST groups, one aged 11 years on average (<i>n</i> = 21) and one aged 15 years (<i>n</i> = 24). The former were compared to ERA SCQ scores at age 11, and the latter at age 15. Nineteen SCQ items were statistically significantly more common in the QA group than in the ERA UK control group at ages 11 and 15. Ten differences persisted into adulthood. These QA-characteristic items ranged across and mapped onto all three standard SCQ domains (social reciprocity, communication, repetitive and stereotyped behaviors). The age 11 CA group scored higher than QA at 11 years across each subscale when all items were considered. However, when only QA-characteristic items were included, only scores for the Repetitive and Stereotyped subscale differentiated QA and CA. When the age 15 comparison was made, no differences were found between CA and QA subscales. QA and CA were associated with similar levels of emotional and conduct problems and overactivity/inattention levels. QA shared many features with CA. QA difficulties extended across all autism domains and were associated to a similar degree with emotional and behavioral problems. However, there were some distinctive elements. Compared to the classic autism profile, the communication domain mainly comprised persistent abnormalities of linguistic expression. In contrast, social reciprocity problems were diffuse, less severe, and declined over time. QA-characteristic repetitive and stereotyped behaviors are broadly expressed and endure into adulthood.</p>","PeriodicalId":131,"journal":{"name":"Autism Research","volume":"18 5","pages":"1062-1076"},"PeriodicalIF":5.3,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/aur.70026","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143712298","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In 2016, a survey was conducted with these early career researchers to identify existing supports and areas of need necessary for a successful and sustained autism research career. Results clearly identified three areas of need: (1) networking opportunities with “change makers,” including funding agencies, journal editors, and senior autism researchers; (2) ensuring early career researchers in the autism research field were diverse and representative of the world; and (3) support from senior researchers to help early career researchers secure their first independent grant and move through promotion. The INSAR Early Career Committee (ECC) was established and developed three initiatives to address the aforementioned gaps: Research Rapid Rounds, the Global Representatives Initiative Pilot (GRIP), and the Mentoring Initiative. The ECC has successfully connected over 34 early career researchers and 40 students/trainees to mentors in 19 unique countries through networking programs and events and has established representatives in seven different countries outside the US and UK.

A cohort of 110 intellectually able children aged 5–11 years with ASC participated in this study. Autistic traits and ED were assessed using the Autism Spectrum Quotient-Children and Child Behavior Checklist, respectively. Intrinsic ERSs, specifically cognitive reappraisal and expressive suppression, were evaluated using the Parent Emotion Regulation Questionnaire, alongside items measuring parental coregulation as an extrinsic ERS. After adjusting for comorbidities (i.e., other neurodevelopmental or neurological disorders), the findings revealed pronounced autistic traits in social skills, attention switching, communication, and imagination correlated with higher ED levels, with parental coregulation mediating this correlation. Notably, the effects of communication and imagination on ED were fully mediated by parental coregulation. Additionally, autistic traits related to imagination were demonstrated to impair the development of cognitive reappraisal, further exacerbating ED. These results provide a deeper understanding of the emotional challenges faced by intellectually able children with ASC. The findings of this study underscore the importance of interventions aimed at enhancing emotion regulation within the parent–child dyad and fostering the development of cognitive reappraisal through imitative tasks.
