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…

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…

Background: ADHD often overlaps with pediatric asthma, leading to difficulties in treatment and management in clinical work. Previous research has explored their correlations but gained different conclusions. Thus, this work aims to fill this evidence gap. Methods: Initially, we conducted a cross-sectional study based on data from the National…

Objectives: There is a need to examine the utility of objective measures of attention-deficit/hyperactivity disorder (ADHD) symptoms in children. Objective measures of ADHD symptoms, such as physical activity, may provide a more nuanced assessment of behavior that can be used to augment traditional cross-informant ratings of ADHD symptoms by…

Background: ADHD and alcohol use are prevalent among college students, but few studies have examined internal restlessness (i.e., the mental discomfort experienced when suppressing hyperactive behaviors) in relation to alcohol use. Consequently, the current study sought to examine a path model testing associations between internal restlessness,…

Background: Research examining the potential effects of stimulant exposure in childhood on subsequent development of substance use disorder (SUD) have focused on differences in the brain reward system as a function of risk. Methods: 18 drug naïve children ages 7 to 12 years (11 High Risk [ADHD + ODD/CD]; 7 Low Risk [ADHD only]), underwent fMRI…

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…

Objective: Around 70% of adolescents with ADHD experience sleep and/or homework problems. Both impairments have been previously associated with neuropsychological deficits but have not been simultaneously examined in adolescents with ADHD and clinical sleep problems. Therefore, this study investigated how sleep problems are associated with…

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…

Objective: ADHD is a neurodevelopmental condition associated with elevated symptoms of inattention and hyperactivity/impulsivity. Symptoms of ADHD typically persist into adulthood and can impair functioning and overall quality of life. In females (including women and people assigned female at birth), ADHD is under-recognized, and knowledge about…

Objective: To examine the association between threatened miscarriage, and neurodevelopmental disorders, including autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD) in offspring by age 14 years. Methods: We used data from the Millennium Cohort Study, a nationally representative longitudinal study of children born in…

Exposure to heavy metals has been associated with affecting children's neurodevelopment, particularly increasing the risk of developing attention-deficit hyperactivity disorder (ADHD). The current exploratory study aims to investigate potential associations between presence of 15 different heavy metals in urine and ADHD. A total of 190 urine…

Objectives: Previous studies have widely demonstrated that inhibition of return (IOR) with audiovisual targets decreases due to audiovisual integration (AVI). It is currently unclear, however, whether the impaired AVI in children with ADHD has effects on IOR. The present study used the cue-target paradigm to explore differences between the IOR of…

Objective: We examined the association between the number, magnitude, and frequency of febrile episodes during the 0 to 4 years of life and subsequent diagnosis of ADHD. Methods: This population-based case-control study in an Israeli HMO, Leumit Health Services (LHS), uses a database for all LHS members aged 5 to 18 years between 1/1/2002 and…

Objective: In recent years, it has been emphasized that various growth factors that affect neurogenesis may lead to ADHD. In this study, we aimed to investigate the role of VEGF, IGF-1, and HIF-1[alpha] growth factors in the etiopathogenesis of ADHD. Method: Levels of VEGF, IGF-1, and HIF-1[alpha] were compared between 40 ADHD children and 40…
