INTRODUCTION We compared the predictive validity of attention deficit hyperactivity disorder (ADHD; Diagnostic and Statistical Manual - IV Edition) and hyperkinetic disorder (HKD; International Classification of Diseases - 10th Edition) while controlling for the presence of comorbid psychopathology. METHOD ADHD and HKD criteria were used to classify 804 clinic-referred children ages 6 to 16 y...

To examine effects of group (Attention-Deficit/Hyperactivity Disorder [ADHD] versus Typically Developing [TD]), sex, and ADHD subtype on "process/optional" measures of executive functioning, children (n = 123; 54 ADHD, 69 TD) aged 8-16 completed subtests from the D-KEFS. No group, sex, or ADHD subtype effects were found on optional measures from the Trail Making, Color-Word Interference, and To...

Altered power of resting-state neurophysiological activity has been associated with autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD), which commonly co-occur. We compared resting-state neurophysiological power in children with ASD, ADHD, co-occurring ASD + ADHD, and typically developing controls. Children with ASD (ASD/ASD + ADHD) showed reduced theta and alpha...

In this study, the authors aimed to examine 4 domains of executive functioning in adults with attention-deficit/hyperactivity disorder (ADHD)--namely interference control, concept shifting, verbal fluency, and verbal working memory. Four groups of participants were included: (a) adults diagnosed with ADHD (ADHD-super(-); n = 20), (b) adults diagnosed with both ADHD and 1 or more comorbid disord...

In the last few years, several computerized tasks have been developed to increase objectivity of diagnosis attention-de?cit hyperactivity disorder (ADHD). Usually, its is based on judgment health professionals using a clinical history that often consists assessment scales completed by caregivers and/or teachers.

Some children may be intellectually gifted, and yet experience behavioral academic difficulties. We examined 82 twice exceptional (2eADHD), having an excellent General Ability Index (GAI) derived from the Wechsler Intelligence Scale for Children-IV (GAI >= 125), a diagnosis of Attention Deficit Hyperactivity Disorder (ADHD). They accounted 8.8% large sample with ADHD, which is as high proportio...

Children with attention deficit hyperactivity disorder (ADHD) or autism spectrum (ASD) individually and those co-occurring ADHD ASD experience higher rates of total anxiety psychiatric comorbidities such as gender dysphoria locomotor skills compared to their typically developing (TD) peers. In this study, it was hypothesized that youth comorbid would levels overall anxiety, specifically separat...

PURPOSE This study aimed to explore the intelligence profiles of Chinese school-aged boys with high-functioning autism spectrum disorder (HFASD) and attention-deficit/hyperactivity disorder (ADHD). Additionally, differences in intelligence quotient (IQ) between the HFASD group and the ADHD group were examined. PATIENTS AND METHODS Thirty-two boys with HFASD, 58 boys with ADHD, and 39 typicall...
