Given the importance of interpersonal interactions for hyperactive children, we evaluated the impact of methylphenidate on specific categories of social behavior in 25 boys, aged 6-12, with attention deficit-hyperactivity disorder (ADHD). These children participated in a 3-week, double-blind, crossover trial with placebo and low (0.3 mg/kg) and moderate (0.6 mg/kg) dosages of methylphenidate during a naturalistic summer research program. Fifteen comparison boys, without problems in attention and behavior, were also observed. In addition to decreasing noncompliance, methylphenidate reduced a combined category of physical and verbal aggression for the ADHD boys, with a significant linear trend across dosages. The medication decreased aggression to levels comparable with those of the comparison boys. There were no medication effects on the frequency of nonsocial or prosocial behaviors. Results are discussed in light of the need to effect durable change in both the quantity and quality of social behavior for hyperactive children.

Purpose: Attention-deficit/hyperactivity disorder (ADHD) increases the risk of road traffic injuries through various mechanisms including higher risky driving behaviors. Therefore, drivers with ADHD are shown to be more prone to road traffic injuries. This study was conducted in a community-based sample of drivers to determine how ADHD affects driving behavior components.

Cognitive control deficits and increased intra-subject variability have been well established as core characteristics of attention deficit hyperactivity disorder (ADHD), and there is a growing interest in their expression at the neural level. We aimed to study neural variability in ADHD, as reflected in theta inter-trial phase coherence (ITC) during error processing, a process that involves cognitive control. We examined both traditional event-related potential (ERP) measures of error processing (i.

Objectives: This study examined the neurocognitive profiles of early adulthood attention-deficit/hyperactivity disorder (ADHD) patients using the Korean version of the Wechsler Adult Intelligence Scale, 4th Edition (K-WAIS-IV) and Continuous Performance Test 3rd Edition (CPT-3) assessment results.
Methods: A total of 105 individuals underwent the K-WAIS-IV assessment, and 68 participants completed the CPT-3. We examined the differences between intelligence subindex scores using paired t-tests and applied Pearson's correlation analysis to determine the correlation between the K-WAIS-IV and CPT-3 scores.

Background: Attention Deficit Hyperactivity Disorder (ADHD) is a prevalent neurodevelopmental disorder which poses challenges for the individuals with the disorder and their families. While stimulant medications are effective, a comprehensive approach, including psychosocial and behavioral interventions, is recommended. There is a growing body of research exploring the potential benefits of mindfulness-based interventions for children with ADHD.

The current paper aimed to estimate the network structure of general psychopathology (internalizing and externalizing symptoms/disorders) among 239 gifted children in Jordan. This cross-sectional study with a convenience sampling method was conducted between September 2023 and October 2024 among gifted children aged 7-12. The Child Behavior Checklist (CBCL) was employed to assess six symptom clusters: conduct problems, attention-deficit/hyperactivity disorder (ADHD), and oppositional defiant problems as externalizing symptoms, and affective problems, anxiety issues, and somatic complaints as internalizing symptoms.
