The aim of this study is to investigate whether the anatomical organization of large-scale brain systems would change in ADHD patients compared to healthy controls. We utilized a structural covariance network (SCN) mapping approach to investigate large-scale networks in 30 drug-naïve ADHD boys and 30 gender- and age-matched controls. The regions showing(More)
Attention deficit/hyperactivity disorder (ADHD) is one of the most prevalent childhood psychiatric disorders. During the past decades, studies have focused on its genetic background and the abnormality of the brain structure and function. Recently, an advanced technique linking these two areas, namely, the imaging genetics emerged and kept growing. Imaging(More)
BACKGROUND The cognitive function of children with either attention deficit hyperactivity disorder (ADHD) or learning disabilities (LDs) is known to be impaired. However, little is known about the cognitive function of children with comorbid ADHD and LD. The present study aimed to explore the cognitive function of children and adolescents with ADHD and(More)
Cognitive-behavioral therapy (CBT) is an efficacious psychological treatment for adults with attention-deficit/hyperactivity disorder (ADHD), but the neural processes underlying the benefits of CBT are not well understood. This study aims to unravel psychosocial mechanisms for treatment ADHD by exploring the effects of CBT on functional brain networks. Ten(More)
Studies of brain alterations in children with attention-deficit/hyperactivity disorder (ADHD) have shown heterogeneous results. The aims of the current study were to investigate white matter microstructure in children using both categorical and dimensional definitions of ADHD and to determine the functional consequences of observed alterations. In a large(More)
As candidate genes of attention--deficit/hyperactivity disorder (ADHD), monoamine oxidase A (MAOA), and synaptophysin (SYP) are both on the X chromosome, and have been suggested to be associated with the predominantly inattentive subtype (ADHD-I). The present study is to investigate the potential gene-gene interaction (G × G) between rs5905859 of MAOA and(More)
OBJECTIVE To explore the memory characteristic in boys with attention-deficit/hyperactivity disorder (ADHD) plus learning disability (LD). METHODS A total of 97 ADHD boys with comorbid LD (ADHD+LD), 97 ADHD boys without comorbid LD (ADHD-LD) and 97 healthy controls (based on the criteria of DSM-IV) were recruited from the outpatient clinic of Peking(More)
OBJECTIVE Mounting evidence suggests that attention deficit/hyperactivity disorder (ADHD) is related with abnormal anatomical asymmetry in some brain regions, such as basal ganglia.However, few cross-sectional studies have examined the abnormalities of anatomical asymmetry in whole brain of ADHD. Thus this cross-sectional study was to explore the anatomical(More)
