BACKGROUND ADHD is diagnosed and treated more often in males than in females. Research on gender differences suggests that girls may be consistently underidentified and underdiagnosed because of differences in the expression of the disorder among boys and girls. One aim of the present study was to assess in a clinical sample of medication naïve boys and(More)
This study investigated the course of and association among changes in autism symptoms, depression symptoms and executive functions (EF) in children with high-functioning autism (HFA). Thirty-four children with HFA and 45 typically developing children (age 9-16) were assessed at baseline and after 2 years. Children with HFA had impaired scores on all(More)
OBJECTIVE To investigate the development of executive function with pronounced emotional salience (hot EF) and less pronounced emotional salience (cold EF) in boys and girls with ADHD relative to typically developing (TD) children. METHOD Seventy-five children with ADHD and 47 TD children were assessed with hot and cold EF tests at baseline and after 2(More)
Symptoms similar to those found in Attention-Deficit/Hyperactivity Disorder (ADHD) often occur in children with Autism Spectrum Disorders (ASD). The objective of the current study was to compare verbal working memory, acquisition and delayed recall in children with High-Functioning Autism (HFA) to children with ADHD and typically developing children (TDC).(More)
OBJECTIVE The aim of the study is to evaluate the long-term near-transfer effects of computerized working memory (WM) training on standard WM tasks in children with Attention-Deficit/Hyperactivity Disorder (ADHD). METHOD Sixty-seven children aged 10-12 years in Vestfold/Telemark counties (Norway) diagnosed with F90.0 Hyperkinetic disorder (ICD-10) were(More)
OBJECTIVE The aim is to investigate the everyday executive function (EF) in children with Tourette syndrome (TS), Inattentive or Combined presentations of ADHD (ADHD-I/ADHD-C), autism spectrum disorders (ASD), and typically developing children (TDC). METHOD Nineteen TS, 33 ADHD-C, 43 ADHD-I, 34 ASD, and 50 TDC participated (8-17 years). Parents completed(More)
OBJECTIVE This study investigates whether performance in a verbal response task (Color-Word Interference Test [CWIT]) and a motor response task (Conners' Continuous Performance Test [CCPT]) discriminates children with Tourette's Syndrome (TS), ADHD, and typically developing children (TDC). METHOD Nineteen children with TS, 79 with ADHD, and 50 with TDC(More)
The aim of the study was to compare executive processes with pronounced (hot) and less pronounced (cold) emotional salience in medication naïve children and adolescents with ADHD-combined (ADHD-C) and ADHD-inattentive (ADHD-I) subtypes. Thirty-six subjects with ADHD-C, 44 with ADHD-I, and 50 healthy controls between 8 and 17 years were assessed with(More)
The aim of the present study was to investigate the ability of children with attention deficit/hyperactivity disorder-combined subtype (ADHD-C) and predominantly inattentive subtype (ADHD-PI) to direct their attention and to exert cognitive control in a forced attention dichotic listening (DL) task. Twenty-nine, medication-naive participants with ADHD-C, 42(More)
The aim of this study was to analyse the development of verbal working memory in children with high-functioning autism compared to children with attention-deficit/hyperactivity disorder and typically developing children. A total of 34 children with high-functioning autism, 72 children with attention-deficit/hyperactivity disorder and 45 typically developing(More)
