..A voxel based investigation of cerebral blood flow was conducted to identify brain function differences in the resting state between children with Attention Deficit Hyperactivity Disorder (ADHD) and normal controls...

..The current findings suggest that non-responders to MPH may have different patterns of rCBF in brain regions, which have been known as a part of frontal-striatal circuitry and posterior attentional system, respectively...

..In addition, our results provide evidence for the possible role of these two polymorphisms in ADHD symptom expression, such as increased response time variability...

..Our aim was to examine whether the presence of a risk allele of the ADRA2A MspI polymorphism is associated with differences in regional cerebral blood flow in boys with ADHD...

..Further studies should clearly elucidate the relationship between treatment response and functional connectivity in the brain according to this genetic polymorphism...

..The aims of this study were to examine the association of the SLC6A2 -3081(A/T) and G1287A polymorphisms with MPH response in ADHD...

..The main objective of this study was to investigate the comorbid disorders and temperamental profiles of full syndrome and subthreshold attention-deficit/hyperactivity disorder (ADHD)...

..001, P=0.036, eta(2)(p)=0.185; F(1)=7.237, P=0.013, eta(2)(p)=0.248). These results suggest that OROS MPH in open-label treatment does not seem to impair sleep and may even improve some aspects of sleep...

..The present study assessed the association between blood lead and urinary cotinine levels and inattentive and hyperactive symptoms and neurocognitive performance in children...

..Our findings do not support SLC6A2 as a major genetic susceptibility factor in ADHD...

..In addition, our results provide evidence that the temperament of Novelty Seeking and ADHD might share molecular genetic characteristics related to the noradrenergic system...

..These findings are in general the same results in other studies on ADHD children in other countries. However, the cross-sectional study design prevents our ability to assess causal relationships...

..We examined the relationship between polymorphisms in the norepinephrine transporter SLC6A2 gene and attentional performance before and after medication in children with ADHD...

..We aimed to explore the relationships between ADHD and BDNF gene polymorphism...

..Although several genome-wide studies on ASD have suggested a number of candidate genes, few studies have reported the association or linkage of specific endophenotypes to ASDs...

..Future studies will examine the validity and reliability of the K-SADS-PL-K in larger samples, including adolescents and community samples on a variety of child and adolescent psychiatric disorders...

..The present study investigated whether teacher ratings and parent ratings of inattentive or hyperactive/impulsive symptoms were differently associated with intelligence or cognitive performance in Korean children...

..This study evaluated neurocognitive changes after switching from immediate release forms of methylphenidate (MPH-IR) to osmotic release oral system methylphenidate (OROS-MPH)...

....

..We retrospectively examined the therapeutic dosage, clinical response, and side effect profiles of long-term clozapine treatment in Korean children and adolescents with refractory EOS or very early onset schizophrenia (VEOS)...

..The results of this study suggest that temperament/character patterns should be considered in accounts of the etiology of problematic Internet use...

....

..Children and adolescents with anxiety disorders have different temperaments and character profiles in accordance with diagnostic groups, which implies the specific pathophysiological mechanism of each anxiety disorder...

..The results of this study suggest that aripiprazole augmentation may be used safely in maladaptive behaviors of some populations of PDD. However, future studies are required to confirm these preliminary findings...

....

..To explore the idiopathic ASD-associated copy number variations (CNVs), we conducted case-control study using whole-genome copy number analysis...

..These changes might be associated with improving ADHD to control attention and motor response to irrelevant environmental stimuli after methylphenidate treatment...

..Mercury (Hg) is toxic to both the reproductive and nervous systems. In addition, glutathione S-transferases (GSTs), which conjugate glutathione to a variety of electrophilic compounds, are involved in the detoxification of Hg...

..025), whereas a population-based case-control study, however, showed no association between ASD and GABRB3 microsatellite polymorphism. Our data provide preliminary evidence that GABRB3 gene is associated with ASD in Korea...
