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…

Objective: We leveraged common genetic variation underlying ADHD, educational attainment (EA) and cognition (COG) to understand the nature of the Behavior Rating Inventory for Executive Functions (BRIEF) and its relationship to academic functioning. Method: Participants were 991 youth, ages 7 to 17, consecutively referred for neuropsychiatric…

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…

Detong Guo; Wenchao Sheng; Yingzi Cai; Jianbo Shu; Chunquan Cai – Journal of Attention Disorders, 2024
Background: Lipid metabolism plays an essential role in nervous system development. Cholesterol deficiency leads to a variety of neurodevelopmental disorders, such as autism spectrum disorder and fragile X syndrome. There have been a lot of efforts to search for biological markers associated with and causal to ADHD, among which lipid is one…

Objective: There is growing evidence of involvement of inflammatory mechanisms in ADHD. Previous studies found significantly higher rates of ADHD among children with FMF. The present study examined the rate of exposure to FMF in children with a later (within a 5-year period) diagnosis of ADHD compared to non-ADHD children. Methods: A…

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…

Objective: Although ADHD is highly heritable, some environmental factors contribute to its development. Given the growing evidence that gut microbiota was involved in psychiatric disorders, we aimed to identify the characteristic composition of the gut microbiota in ADHD. Methods: We recruited 47 medication-naive children and adolescents with…

Israel Moses Gross; Yangfeifei Gao; Mary J. Lee; Alison E. Hipwell; Kate Keenan – Journal of Attention Disorders, 2024
Objective: The goal of the present study is to describe the ADHD phenotype from childhood to adolescence in Black and White girls in a community sample. Method: Primary caregivers enrolled in the population-based, longitudinal Pittsburgh Girls Study reported on girls' ADHD symptoms and impairment from ages 7 to 17; diagnostic subtypes were…

Children born to parents with fewer years of education are more likely to have depression, anxiety, and attention-deficit hyperactivity disorder (ADHD), but it is unclear to what extent these associations are causal. We estimated the effect of parents' educational attainment on children's depressive, anxiety, and ADHD traits at age 8 years, in a…

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…

Russell Schachar; Jennifer Crosbie – Journal of Attention Disorders, 2024
Objective: To examine the theoretical and empirical contribution of Joe Biederman and his colleagues to the understanding of executive function (EF) and ADHD. Method: We searched PubMed for references to EF in Biederman's publications and conducted a narrative review of this literature. Results: In 50 or more papers using neuropsychological tests,…

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…

Marrium Mansoor; Benjamin Katz – Journal of Attention Disorders, 2023
Objective: Understanding the association between polygenic risk for ADHD and cognition throughout aging has not been widely studied. This study aimed to determine whether ADHD risk influences cognitive performance among individuals at both young-old and middle-old age. Method: Participants from the Health and Retirement Study, a biennial survey of…

Daniel A. Geller; Mia Grossman – Journal of Attention Disorders, 2024
Objective: To use a family genetic study to evaluate familial risk of obsessive compulsive disorder (OCD) and common comorbid illnesses in first-degree relatives of pediatric-onset probands with primary OCD. Method: One hundred and thirty youth with OCD and their 133 siblings and 241 parents and 49 pediatric controls were directly evaluated along…
