Attention-deficit/hyperactivity disorder (ADHD) has been shown to continue into old age. Studies in children and younger adults show a reduction in hyperactive-impulsive symptoms, whereas the number of inattentive symptoms stays stable. The current study examined the lifetime stability of ADHD symptoms up to old age. Data on ADHD diagnosis and symptoms were collected in a two-phase side-study (...

Emotional-motivational dysfunctions may significantly contribute to symptoms of attention-deficit/hyperactivity disorder (ADHD). Hyperactive-impulsive symptoms and sensation seeking could be the result of a search for reinforcers, and cognitive dysfunctions might be due to a low motivational drive. Emotional-motivational dysfunctions could also explain social dysfunctions in ADHD patients becau...

Introduction: ADHD is one of the most common disorders among school children throughout the world. Parents of these children are faced with more conflicts than normal children's parents. The Purpose of his study was to evaluate and compare the mental health status of mothers having children with attention deficit / hyperactivity disorder versus mental health of mothers having normal primary sch...

Handedness is associated with cerebral hemispheric differences. Normal patterns of brain asymmetries are needed for the neural processing of attention. In order to identify ADHD (Attention Deficit Hyperactive Disorder) children, the use of checklists allows a greater level of accuracy. Here, we will review our data on this subject. Our first study investigated the psychometric properties of a s...

The objective of this study was to evaluate the relationship between attention deficit hyperactive symptoms and temperament and character profiles among preschool-age children. Total 694 preschool age children (mean age=5.7±0.45) were recruited for the study. The preschool Temperament and Character Inventory (psTCI) and DuPaul ADHD rating scale (K-ARS) were applied to evaluate the children. Sta...

Introduction: Attention Deficit Hyperactive Disorder (ADHD) has been described by the American Psychiatric Association (APA, 1994) as age-inappropriate inattention, impulsivity, and hyperactivity. Children with attention deficit hyperactive disorder comprise a heterogeneous population considerable variation across children to extent in which they demonstrate all symptoms. is currently understoo...

This study aims to compare maternal uniparental disomy 15 (mUPD) and a paternal deletion of 15q11-13 (DEL) of Prader-Willi syndrome (PWS) in regard to autism spectrum disorders (ASD). Forty-five Japanese individuals with PWS were recruited from a single recruitment center. The participants consisted of 22 children (aged from 6 to 12) and 23 adolescents (aged from 13 to 19). Six children and sev...

Two core symptoms characterize Attention Deficit Hyperactivity Disorder (ADHD) subtypes: inattentiveness and hyperactivity-impulsivity. While previous brain imaging research investigated ADHD as if it was a homogenous condition, its two core symptoms may originate from different brain mechanisms. We, therefore, hypothesized that the functional connectivity of cortico-striatal and attentional ne...

Although advances in neonatal care over the past century have resulted in increased rates of survival among at-risk births, including infants with low birth weight, we have much to learn about psychological outcomes in this population. In particular, despite growing evidence that low birth weight may be associated with an increased risk for Attention-Deficit/Hyperactive Disorder (ADHD) symptoms...

BACKGROUND The aims of this study were to determine the time course of improvements in attention deficit hyperactivity disorder (ADHD) clinical symptoms and neurocognitive function in a realistic clinical setting, and the differences in ADHD symptom improvement using different classifications of ADHD subtypes. METHODS The Child Behavior Checklist (CBCL) was completed by parents of ADHD childr...
