Brief Summary
The objective of this study is to identification of neuropsychological, genetic and neuroimaging markers and treatment response predictors of attention-deficit/hyperactivity disorder (ADHD). Participants who take the standardized pharmacotherapy (methylphenidate or atomoxetine) for ADHD will be observed for 52 weeks. They will do several neuropsychological, neuroimaging and genetic tests at visit 1\~6.

Outcome Measures
Primary Outcomes (5)
Wide genome analysis regarding genetic polymorphisms as predictors of treatment response in Attention-Deficit/Hyperactivity Disorder(ADHD).
Genome wide case-control association analysis will be operated with qualified phenotype and assigned intermittent phenotype.
visit 1 (-week 8)
Neuroimaging analysis as predictors of treatment response in Attention-Deficit/Hyperactivity Disorder(ADHD).
Thickness of cortex, anatomical relation will be compared with 3 tesla MRI. In addition, brain circuit for delayed aversion, delayed frustration, time processing and resting state.
visit 1 (-week 8)
Drug effectiveness is assessed using ADHD rating scale, CGI -S (Clinical Global Impression - Severity scale) and CGI-I (Clinical Global Impression - Improvement scale).
visit 1 (-week 8)
Neuropsychological markers as the treatment response predictable factor of ADHD using a complex neuropsychological test consisting of SSRT, delayed aversion, delayed frustration, time processing, ATA
Using a complex neuropsychological test consisting of The stop-signal reaction time (SSRT) task, delayed aversion, delayed frustration, time processing, Advanced tets of Attention (ATA).
visit 1 (-week 8)
Comorbidity assessment using a composite measure consisting of K-PRC, C-SSRS, TCGI, and DCDQ
It is assessed using a composite measure consisting of Korean Personality Rating Scale for Children (K-PRC), Columbia Suicide Severity Rating Scale (C-SSRS), The Tic Severity Scale (TCGI), and The Developmental Coordination Disorder Questionnaire (DCDQ).
visit1 (-week 8)
Other Outcomes (8)
Change from baseline in treatment response effectiveness of pharmacotherapy at week12
visit 3 (week12)
Change from baseline in treatment response effectiveness of pharmacotherapy at week 24
visit 4 (week 24)
Change from baseline in treatment response effectiveness of pharmacotherapy at week 36
visit 5 (week 36)

Study Arms (2)
ADHD group
Children and adolescents who met the Diagnostic and Statistical Manual IV Text Revision (DSM-IV-TR) diagnostic criteria for ADHD and needed pharmacotherapy. Subjects will be taking Methylphenidate or Atomoxetine for 52 weeks.
Normal control group
Children and adolescents will be recruited by advertisement, and will be assigned to normal group if they do not meet the Diagnostic and Statistical Manual IV Text Revision (DSM-IV-TR) diagnostic criteria for ADHD .
Interventions
Subjects of ADHD group will be taking methylphenidate or atomoxetine for 52 weeks.
