Characteristic Executive Dysfunction for High-Functioning Autism Sustained to Adulthood / Rao XIE in Autism Research, 13-12 (December 2020)  

Public ISBD [article]  inAutism Research > 13-12 (December 2020) . - p.2102-2121 Titre : Characteristic Executive Dysfunction for High-Functioning Autism Sustained to Adulthood Type de document : Texte imprimé et/ou numérique Auteurs : Rao XIE, Auteur ; Xiao SUN, Auteur ; Li YANG, Auteur ; Yanqing GUO, Auteur Article en page(s) : p.2102-2121 Langues : Anglais (eng) Mots-clés : Asperger's syndrome  executive function  high-functioning autism spectrum disorder  meta-analysis Index. décimale : PER Périodiques Résumé : The comprehensiveness and severity of executive dysfunction in high-functioning autism (HFA) spectrum disorder have not reached a unified conclusion especially in patients in adulthood. Clarifying this issue is critical for guiding clinical diagnosis and targeted intervention. The primary objective of the present meta-analysis was to study the characteristics of executive function (EF) in adults with HFA compared to typically developing (TD) adults, by taking five key components into consideration, including inhibition, working memory, flexibility, planning, and fluency. The PubMed and Embase databases were searched to identify peer-reviewed studies that compared EF in adults with and without HFA from 1980 to November 2018. Hedges' g effect sizes were computed to measure the primary outcome. Moderators like age, sex, and diagnostic tools were controlled using meta-regressions. Forty-two studies satisfying the selection criteria were included, which resulted in a large sample size of 2419 participants. A moderate overall effect size for reduced EF across domains was found in adults with HFA, compared with TD (g = 0.57, 95% confidence interval 0.47-0.66). Subsequently, a broad executive dysfunction was found in adults with HFA in this study (flexibility [g = 0.69], planning [g = 0.64], inhibition [g = 0.61], working memory [g = 0.48], fluency [g = 0.42]), with the predominated impairment on flexibility and planning. Taken together, these results provide evidence for the executive dysfunction hypothesis and may assist in the clinical diagnosis and targeted intervention, suggesting the necessity of sustained intervention on EF for individuals with HFA from childhood to adulthood. LAY SUMMARY: The meta-analysis explored the characteristics of EF in adults with high-functioning autism (HFA) comparing to typically developing controls. Moderate effect sizes for reduced EF across domains were found in adults with HFA, with the flexibility and planning being the most predominately impaired. A comprehensive measurement of EF in adults with HFA has important clinical implications for the diagnosis, treatment, prognosis, and a fundamental understanding for developmental trajectory of these patients.

The possible involvement of genetic variants of NET1 in the etiology of attention-deficit/hyperactivity disorder comorbid with oppositional defiant disorder / Lu LIU in Journal of Child Psychology and Psychiatry, 56-1 (January 2015)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 56-1 (January 2015) . - p.58-66 Titre : The possible involvement of genetic variants of NET1 in the etiology of attention-deficit/hyperactivity disorder comorbid with oppositional defiant disorder Type de document : Texte imprimé et/ou numérique Auteurs : Lu LIU, Auteur ; Jia CHENG, Auteur ; Haimei LI, Auteur ; Li YANG, Auteur ; Qiujin QIAN, Auteur ; Yufeng WANG, Auteur Article en page(s) : p.58-66 Langues : Anglais (eng) Mots-clés : ADHD  ODD  NET1  association Index. décimale : PER Périodiques Résumé : Background Attention-deficit/hyperactivity disorder (ADHD) and oppositional defiant disorder (ODD) often coexist and shared some genetic influences. Evidence from the existing literature indicated that comorbid with ODD may increase the heterogeneity of ADHD genetics. Our present study sought to investigate the role of norepinephrine transporter gene (NET1) for ADHD comorbid with ODD. Methods Six single nucleotide polymorphisms (SNPs) of NET1 were genotyped for a total of 1,815 ADHD cases, including 587 subjects (32.3%) with ODD. Chi-square tests were conducted for pseudo case–control study comparing allelic and genotypic distributions between ADHD with and without ODD. Among them, there were 1,249 probands together with their parents composing trios for family-based association studies using transmission disequilibrium tests (TDTs). In addition, 1,337 ADHD probands have detailed information of ODD symptoms and were included for quantitative analyses with genotypes using analyses of covariance (ANCOVA). To consider the overlap and correlation of other comorbidities with ODD and eliminate their potential confounding effect, we further repeated above analyses for ‘pure ADHD+ODD’ versus ‘ADHD-only’ after excluding other comorbidities except for ODD. Results The pseudo case–control study showed different allelic and genotypic distributions of SNP rs3785143 between ADHD with ODD and those without ODD. Family-based association tests indicated overtransmission of the T allele of rs3785143 in ADHD with ODD trios, but no biased transmission in those without ODD. ANCOVA showed association between genotypes of rs3785143 with ODD symptoms in ADHD probands, especially with ‘Argumentative/Defiant Behavior (ADB)’ dimension after controlling gender, age, clinical subtypes and intelligence. Above association still existed after removing the samples with other comorbidities. Conclusion NET1 was associated with comorbidity of ODD and ODD symptoms in ADHD probands. Our findings emphasize the importance of considering the comorbidity of ODD in ADHD genetic studies, especially ADHD with ADB. However, further replication in independent sample or different populations is still needed.

The trajectory of attention deficit hyperactivity disorder symptoms and its dynamic relationship with inhibitory control / Tao PANG in Journal of Child Psychology and Psychiatry, 66-7 (July 2025)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 66-7 (July 2025) . - p.980-993 Titre : The trajectory of attention deficit hyperactivity disorder symptoms and its dynamic relationship with inhibitory control Type de document : Texte imprimé et/ou numérique Auteurs : Tao PANG, Auteur ; Li YANG, Auteur ; Yuxin LIU, Auteur ; Suhua CHANG, Auteur Article en page(s) : p.980-993 Langues : Anglais (eng) Mots-clés : Attention Deficit Hyperactivity Disorder  inhibitory control  longitudinal study  latent growth curve model  bivariate latent change score model Index. décimale : PER Périodiques Résumé : Background Attention Deficit Hyperactivity Disorder (ADHD) is a prevalent neurodevelopmental disorder in childhood, characterized by symptoms of inattention, hyperactivity, and impulsivity. Impaired inhibitory control is observed in the majority of individuals with ADHD. Understanding the relationship between inhibitory control and the developmental trajectory of ADHD is essential for informing clinical prognosis and guiding early interventions. Methods We utilized Latent Growth Curve Modeling (LGCM) to map the developmental course of ADHD symptoms using data from the Adolescent Brain Cognitive Development study. Concurrently, we examined the longitudinal correlation between inhibitory control and ADHD symptoms at corresponding time points. Additionally, a Bivariate Latent Change Score Model (BLCSM) was employed to investigate the relationship between changes in inhibitory control and ADHD symptoms. We also integrated Polygenic Risk Scores (PRS) into the LGCM as predictors to explore the impact of genetic factors associated with inhibitory control and ADHD on the trajectory of ADHD symptoms. Results The LGCM analysis demonstrated that baseline inhibitory control influenced both the initial state and the rate of change of ADHD symptoms. Inhibitory control exhibited both concurrent and prospective associations with ADHD symptoms. Notably, the BLCSM revealed that changes in inhibitory control could predict future changes in ADHD symptoms, and vice versa. Dynamic changes in inhibitory control were found to affect future changes in ADHD symptoms. Additionally, the PRS for inhibitory control and ADHD were significantly linked to the initial state and rate of change of ADHD symptoms. Conclusions Our findings underscore a sustained correlation between inhibitory control and ADHD symptoms, highlighting the critical association between inhibitory control and the developmental trajectory of ADHD in children. Furthermore, the predictive value of inhibitory control for ADHD suggests a new avenue for early intervention, potentially improving the prognosis for ADHD patients.
