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).
