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.

Feasibility of Group Parent Training for Children with Autism Spectrum Disorder and Disruptive Behavior: A Demonstration Pilot / T Lindsey BURRELL in Journal of Autism and Developmental Disorders, 50-11 (November 2020)

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.

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.

Rhythmic attentional sampling in autism / Tamar KOLODNY ; Kristin M. WOODARD ; Aydin TASEVAC ; Wesley R. GANZ ; Hannah M. REA ; Evangeline C. KURTZ-NELSON ; Sara Jane WEBB ; Scott O. MURRAY in Autism Research, 16-11 (November 2023)

MURRAY, Auteur Article en page(s) : p.2090-2099 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Abstract Individuals diagnosed with autism often display alterations in visual spatial attention toward visual stimuli, but the underlying cause of these differences remains unclear. Recent evidence has demonstrated that covert spatial attention, rather than remaining constant at a cued location, samples stimuli rhythmically at a frequency of 4-8?Hz (theta). Here we tested whether rhythmic sampling of attention is altered in autism. Participants were asked to monitor three locations to detect a brief target presented 300-1200?ms after a spatial cue. Visual attention was oriented to the cue and modified visual processing at the cued location, consistent with previous studies. We measured detection performance at different cue-target intervals when the target occurred at the cued location. Significant oscillations in detection performance were identified using both a traditional time-shuffled approach and a new autoregressive surrogate method developed by Brookshire in 2022. We found that attention enhances behavioral performance rhythmically at the same frequency in both autism and control group at the cued location. However, rhythmic temporal structure was not observed in a subgroup of autistic individuals with co-occurring attention-deficit/hyperactivity disorder (ADHD). Our results imply that intrinsic brain rhythms which organize neural activity into alternating attentional states is functional in autistic individuals, but may be altered in autistic participants who have a concurrent ADHD diagnosis.
