Characterizing the autism spectrum phenotype in DYRK1A-related syndrome / Evangeline C. KURTZ-NELSON in Autism Research, 16-8 (August 2023)

While many individuals with DYRK1A syndrome are diagnosed with ASD, they may present with a unique profile of ASD traits. We present a comprehensive characterization of the ASD profile in children and young adults with LGDs in DYRK1A. Individuals with LGD variants in DYRK1A (n=29) were compared to children who had ASD with no known genetic cause, either with low nonverbal IQ (n=14) or average or above nonverbal IQ (n=41). ASD was assessed using the ADOS-2, ADI-R, SRS-2, SCQ, and RBS-R. Quantitative score comparisons were conducted, as were qualitative analyses of clinicians' behavioral observations. Diagnosis of ASD was confirmed in 85% and ID was confirmed in 89% of participants with DYRK1A syndrome. Individuals with DYRK1A syndrome showed broadly similar social communication behaviors to children with idiopathic ASD and below-average nonverbal IQ, with specific challenges noted in social reciprocity and nonverbal communication. Children with DYRK1A syndrome also showed high rates of sensory-seeking behaviors. Phenotypic characterization of individuals with DYRK1A syndrome may provide additional information on mechanisms contributing to co-occurring ASD and ID and contribute to the identification of genetic predictors of specific ASD traits.

Examining Feasibility and Outcomes of the PEERS® for Preschoolers Program / Reina S. FACTOR in Journal of Autism and Developmental Disorders, 53-5 (May 2023)

There is a paucity of evidence-based interventions explicitly targeting social skill development for young children with ASD and few actively integrate caregivers. The PEERS® program, an evidence-based caregiver-assisted social skills program, was extended for young children with ASD (i.e., PEERS® for Preschoolers (P4P)). This pilot study expands upon initial results by examining the feasibility of a briefer intervention period and the effectiveness in improving child social skills among 15 children with ASD. Results suggest P4P recruitment, participant retention, and implementation are feasible across clinicians and sites. Further, P4P appears to improve social skills, maintained post-intervention. Future research might examine mechanisms that lead to results.

We conducted an open feasibility trial of group-based RUBI parent training in 18 children (mean age 6.12 ± 1.95 years) with ASD and disruptive behaviors. Parents participated in one of five groups (3 to 4 parents per group). Eighty-three percent of participants completed the 24-week trial. Session attendance was moderate (74.2%). All parents indicated that they would recommend the treatment. Therapists demonstrated 98.8% fidelity to the manual. Eleven of 18 (64.7%) participants were rated as much/very much improved by an independent evaluator at Week 24. Preliminary efficacy findings justify further study.

Increased alpha power in autistic adults: Relation to sensory behaviors and cortical volume / Scott O. MURRAY ; Daniela L. SECZON ; Mark PETTET ; Hannah M. REA ; Kristin M. WOODARD ; Tamar KOLODNY ; Sara Jane WEBB in Autism Research, 18-1 (January 2025)

We investigated alpha-band EEG activity in autistic adults (n 29) compared with a nonautistic group (n 23) under various stimulus-driven and resting-state conditions. The autistic group showed consistently higher alpha amplitude across all time points. In addition, there was proportionally more suppression of alpha at stimulus onset in the autistic group, and alpha amplitude in this stimulus-onset period correlated with sensory behaviors. Recent research suggests a link between subcortical structures' volume and cortical alpha magnitude. Prompted by this, we explored the association between alpha power and the volume of subcortical structures and total cortical volume in ASD. Our findings indicate a significant correlation with total cortical volume and a group by hippocampal volume interaction, pointing to the potential role of anatomical structural characteristics as potential modulators of cortical alpha oscillations in ASD. Overall, the results highlight altered alpha in autistic individuals as potentially contributing to the heightened sensory symptoms in autistic compared with nonautistic adults.

While previous research has examined correlations between aggression and social skills cross sectionally, research is needed to better understand the interrelations between these behaviors over time. Method In a sample of 280 autistic children (ages 6–11 years), parallel process growth modeling and regression were used to examine changes in social skills and aggression across three time points, as well as the interrelations between social skills and aggression. A confirmatory factor analysis (CFA) was also conducted on the measure of aggression (the Aberrant Behavior Checklist), which yielded separate factors for aggression towards others and self-injurious behaviors (SIB). Results Over time, aggression towards others decreased and social skills improved, but SIB did not change. While initial levels of social skills, aggression towards others, and SIB were inter-related, there were no significant relations between initial scores and subsequent changes in any domain. Conclusions Interventions for aggression in school-aged autistic children should consider aggression towards others, SIB, and social skills as separate targets, as changes in one domain did not appear to be related to changes in other domains.
