The nature of time-processing alterations in ADHD was assessed by means of duration judgments and temporal set-shifting tasks lasting several seconds and milliseconds. After training with visual sample stimuli for long and short durations, 31 children with ADHD and 29 controls estimated the durations of test stimuli. During testing, the temporal co...

"Jitter" involves randomization of intervals between stimulus events. Compared with controls, individuals with ADHD demonstrate greater intrasubject variability (ISV) performing tasks with fixed interstimulus intervals (ISIs). Because Gaussian curves mask the effect of extremely slow or fast response times (RTs), ex-Gaussian approaches have been ap...

Few studies of ADHD prevalence have used population-based samples, multiple informants, and Diagnostic and Statistical Manual of Mental Disorders (4th ed.; DSM-IV) criteria. Moreover, children who are asymptomatic while receiving ADHD medication often have been misclassified. Therefore, we conducted a population-based study to estimate the prevalen...

Given the burden of ADHD, efforts should be made to establish a system for the early identification and management.

Methylphenidate (MPH) is the most often prescribed medication for treatment of ADHD. However, many of its specific cellular and molecular mechanisms of action, as well as developmental consequences of treatment, are largely unknown. This review provides an overview of current understanding of MPH efficacy, safety, and dosage in adult and pediatric ...

The objective of this study was to test whether physicians' attitudes regarding the impact of ADHD on health-related quality of life (HRQL) explain differences in practices for prescribing psychostimulants in children. In a cross-sectional survey, U.S.-based pediatricians and psychiatrists ("physicians") used the Paper-Standard Gamble--a widely use...

This suggests that the EF pathway in contemporary multiple pathway models of ADHD etiology may be particularly relevant in higher SES parts of the population.

The comorbidity of ADHD and reading difficulties (ADHD + RD) is believed to be a disability distinct from ADHD alone, with unique challenges faced by individuals suffering from one disability versus the other. We aimed to examine the differential effect of 8 weeks of cognitive training on reading abilities and on executive functions, through use of...

Bilingualism might prove to be an added burden for adults with ADHD, leading to reduced EF abilities. Alternatively, the current findings might be ascribed to over- or under-diagnosis of ADHD due to cultural differences between groups. These issues should be pursued in future research.

These findings support the hypotheses that EFs develop hierarchically and that EF deficits in ADHD are more prominent in actively developing EFs. They also emphasize ADHD as a developmental disorder.
