| Outline of Final Research Achievements |
The aim of the present study is to clarify the neural basis of attention-deficit/ hyperactivity disorder (ADHD). We examined whether the cortico-cerebellar executive function network is altered in children with ADHD and whether catechol-O-methyltransferase (COMT) polymorphism is associated with the altered network using resting-state functional MRI. Relative to TD controls, children with ADHD showed significantly lower functional connectivity of the right Crus I/II with the left dorsolateral prefrontal cortex. Additionally, the functional connectivity of children with ADHD was modulated by COMT polymorphism. These results suggest that COMT polymorphism effects on the cortico-cerebellar executive function network, which effects on executive function and ADHD symptoms. Further imaging genetics study may lead to the development of objective diagnostic and therapeutic effect evaluation system according to ADHD pathophysiology.
