Description of intervention(s) / exposure
The goal of this study was to examine the resting-state functional connectivity within the fronto-striatal-insular network in subjects with ADHD and in healthy controls. Twenty-nine boys with ADHD engaged in resting-state fMRI scanning for 8 minutes during which they were instructed to lie with their eyes closed, think of nothing systematically, and not fall asleep.

Outcomes
Primary outcome [1] 3483 0
The reduced functional connectivity was mainly distributed among the right fronto-striatal-insular network (middle frontal gyrus, medial frontal gyrus, insula, paracentral lobule and superior frontal gyrus).
Timepoint [1] 3483 0
Assessed in neural network of children with ADHD at baseline (without any treatment).
Secondary outcome [1] 5815 0
Patients with ADHD had significantly less power in low-frequency oscillations (0.01 Hz ~ 0.1 Hz) in relation to healthy controls.
Timepoint [1] 5815 0
We assessed this outcome in children with ADHD at baseline (without any treatment).

Summary
Brief summary
The primary purpose of the present study was to use spatial ICA to identify differences in the resting-state functional connectivity of the fronto-striatal-insular network between healthy controls and patients with ADHD. We hypothesize that the pathophysiology of ADHD involves dysfunctional interaction or connectivity among regions of the fronto-striatal-insular network. ICA was used to calculate spatially independent, temporally synchronous regions (i.e., network) (Calhoun et al 2004); the fronto-striatal-insular network for each subject was selected using a spatial template to identify the network of interest. Study hypotheses were then tested by comparing the spatial-temporal characteristics of the fronto-striatal-insular network within and between groups.
