Background: Little is known about the influence of sex on the course of attention-deficit/hyperactivity disorder (ADHD) and its comorbid psychiatric conditions. The purpose of this study was to examine the effect of sex on the course and psychiatric correlates of ADHD from childhood into adolescence. Methods: Two identically designed,…

Despite the large number of children that the Surgeon General of the United States estimated to be suffering from a mental disorder (Office of the Surgeon General, 2000), the majority of childhood disorders are undiagnosed and untreated. The negative effect of childhood disorders on a child's academic, social, and psychological development can be…

Objective: This study aimed to replicate and extend previous work showing an association between maternal pre-pregnancy adiposity and risk for attention deficit hyperactivity disorder (ADHD) symptoms in children. Methods: A Swedish population-based prospective pregnancy-offspring cohort was followed up when children were 5 years old (N = 1,714).…

Neurophysiological studies yield contrary results whether attentional problems of patients with attention-deficit/hyperactivity disorder (ADHD) are related to early visual processing deficits or not. Evoked gamma-band responses (GBRs), being among the first cortical responses occurring as early as 90 ms after visual stimulation in human EEG, have…

In typically developing children, boys are more commonly diagnosed than girls with disruptive behavior disorders, namely, attention-deficit/hyperactivity disorder, conduct disorder, and oppositional defiant disorder. For children with intellectual disability (ID), the evidence for this gender effect is less clear. In this report we examine gender…

Rating scales developed to measure child emotional and behavioral problems typically are so long as to make their use in progress monitoring impractical in typical school settings. This study examined two methods of selecting items from existing rating scales to create shorter instruments for use in assessing response to intervention. The…

The purpose of the study was to evaluate neuropsychological and behavioral rating measures of executive functions (EF) in children with two subtypes of ADHD, Asperger syndrome (AS), and controls. Relative to the control group, the clinical groups experienced more difficulty in EF. The AS group showed the most difficulty in emotional control,…

We examined associations between children's peer relationships and (a) their parents' social competence as well as (b) their parents' behaviors during the children's peer interactions. Participants were families of 124 children ages 6-10 (68% male), 62 with ADHD and 62 age- and sex-matched comparison youth. Children's peer relationships were…

Increasing numbers of students in UK universities are presenting with a diagnosis of attention deficit hyperactivity disorder (ADHD). However, the impact of ADHD symptomatology on academic achievement in university students in the UK has not previously been explored. This study investigates the prevalence of self-reported ADHD symptoms…

This article seeks to evaluate and take further the discussion put forward by Visser and Jehan ("Emotional and Behavioural Difficulties" 14, no. 2: 127-40). It begins by focusing on the biomedical discourse, its dominance in the academic and professional literature and why the existence of Attention Deficit Hyperactivity Disorder (ADHD) as a…

Objective: In developing psychosocial approaches to augment outcomes for medication-treated adults with ADHD, it is important to understand what types of life-impairments are most affected by continued ADHD symptoms that occur despite medication treatment. This may assist in delineating targets for interventions, as well as assessments of…

Aim: To study the value and reliability of an examination of neurological soft-signs, often used in Sweden, in the assessment of children with attention-deficit-hyperactivity disorder (ADHD), by examining children with and without ADHD, as diagnosed by an experienced clinician using the DSM-III-R. Method: We have examined interrater reliability…

Objective: The present study examines the ability of children with ADHD to make inferences and monitor ongoing understanding of texts, to shed light on their academic difficulties. Method: A total of 29 boys with ADHD and 41 comparison boys between the ages of 7 and 12 participated. Three tasks measure how boys create and evaluate inferences,…

Difficulties in phonological processing and reading that characterize developmental dyslexia have been suggested also to affect those with attention-deficit/hyperactivity disorder (ADHD). However, it is not known to what extent various intervening factors, such as low intelligence quotient or age, explain the observed difficulties. In this study,…

Objective: Understanding placebo response is a prerequisite to improving clinical trial methodology. Data from placebo-controlled trials of atomoxetine in the treatment of children and adolescents with attention-deficit/hyperactivity disorder (ADHD) were analyzed to identify demographic and clinical characteristics that might predict placebo…
