title: Abnormal neural activity in children with attention deficit hyperactivity disorder: a resting-state functional magnetic resonance imaging study.
abstract: In this study, a newly reported regional homogeneity approach was used to analyze blood oxygen level-dependent functional magnetic resonance imaging data on resting state in boys with attention deficit hyperactivity disorder. Boys with attention deficit hyperactivity disorder showed decreased regional homogeneity in the frontal-striatal-cerebellar circuits, but increased regional homogeneity mainly in the occipital cortex. Our findings are consistent with the hypothesis of abnormal frontal-striatal-cerebellar circuits in attention deficit hyperactivity disorder. The regional homogeneity approach may be a potentially useful method in exploring the pathophysiology of attention deficit hyperactivity disorder.
