Objective: To explore the association between telomere length (TL) and attention deficit hyperactivity disorder (ADHD) symptoms in children at 6-12 years. Method: Data from 1,759 children belonging to the HELIX project cohorts and the Asturias, Gipuzkoa and Valencia cohorts of INMA project were included. TL was determined by blood sample using a…

Kwangmi Ahn; Jenny Jean; Luke J. Norman; Philip Shaw – Journal of Attention Disorders, 2025
Objectives: Although extensive research has documented associations between Attention-Deficit/Hyperactivity Disorder (ADHD) and differences in resting-state electroencephalography (EEG) oscillatory activity, the causal nature of these relationships remains uncertain. This study aimed to determine whether there is a causal relationship between…

The physiological functions of micronutrients in neurodevelopment are well documented, but their protective effects on neurodevelopmental disorders remain controversial. We assessed the associations between micronutrients and three main neurodevelopmental disorders, that is, autism spectrum disorder (18,381 cases), attention-deficit/hyperactivity…

Carla A. Wall; Frederick Shic; Elizabeth A. Will; Quan Wang; Jane E. Roberts – Journal of Autism and Developmental Disorders, 2025
Purpose: Fragile X syndrome (FXS) is a single-gene disorder characterized by moderate to severe cognitive impairment and a high association with autism spectrum disorder (ASD) and Attention-Deficit/Hyperactivity Disorder (ADHD). Atypical visual attention is a feature of FXS, ASD, and ADHD. Thus, studying early attentional patterns in young…

Zequn Zheng; Dihui Cai – Journal of Attention Disorders, 2025
Background: While observational studies have established a connection between attention deficit hyperactivity disorder (ADHD), autism spectrum disorder (ASD), and heightened risk for cardiovascular diseases (CVD), the causal relationships are not well-defined. This study is designed to examine the causality between ASD, ADHD, and CVD risk as well…

Adaptive behaviour refers to the everyday skills that individuals are expected to have to function independently, based on their age and societal norms. Currently, we know little about the role of genetic and environmental factors in parent-rated adaptive behaviours in early infancy. The aim of this study was to investigate the aetiological…

Ellen C. Masters; Kevin M. Antshel; Wendy R. Kates; Natalie Russo – Journal of Autism and Developmental Disorders, 2025
Background: Sensory processing differences are reported both in children with ADHD and in children with autism. Given the substantial overlap between autism and ADHD, the current study examined which sensory features were uniquely predictive of autistic traits after controlling for ADHD symptoms, age, IQ, and sex in a sample of children and…

Yoon-Mi Hur – Journal of Attention Disorders, 2025
Objective: The association between perceived stress (PS) and ADHD symptoms in adulthood is well established, yet the underlying mechanisms remain unclear. This study employed a genetically informative design to investigate the roles of gene-environment (GE) correlation and gene-environment interaction (G×E) in explaining this association. Three…

Zuhal Koc Apaydin; Meryem Kasak; Ozlem Karakaya; Hakan Ogutlu; Mustafa Ugurlu; Fiona McNicholas – Journal of Attention Disorders, 2025
Objective: This study aimed to investigate the relationship between Cognitive Disengagement Syndrome (CDS) symptoms in children/adolescents and their parents within the Turkish population, examining the association with co-occurring ADHD symptoms, peer/social relationships, and total difficulties. Method: The study included 229 parents aged 18 to…
