Abstract
BackgroundStructural and functional alterations occur in the caudate of patients with attention-deficit/hyperactivity disorder (ADHD). Here we aimed to investigate the functional connectivity between the dorsal caudate and other brain regions in ADHD children. MethodsResting-state functional connectivity from 30 ADHD and 33 age- and gender-matched “normal” children were measured by functional Magnetic Resonance Imaging. ResultsPositive connectivity with dorsal caudate was observed in the prefrontal areas, cingulate cortex and temporal lobe. Negative functional connectivity was observed in the precuneus, occipital cortices and cerebellum. The connectivity of left dorsal caudate to left inferior frontal gyrus was correlated with severity of ADHD. ConclusionsConnectivity of dorsal caudate with several brain regions was identified in ADHD children.
