Seed-based functional connectivity (FC) analysis was performed.Results: Four brain areas with higher FC values were identified in ADHD children. These four areas were the left middle frontal gyrus, right middle frontal gyrus, right superior temporal gyrus and left parahippocampal gyrus (P < 0.05). The results of the CPT show that the number of omission errors was significantly higher in the children with ADHD than in the TD group (5.13± 5.12 vs 2.18± 2.36, P = 0.000). The commission number in the ADHD group was also significantly higher than that of the TD group (4.03± 6.56 vs 2.00± 2.85, P = 0.002). However, no statistically significant difference was observed in the correct reaction time between the two groups (641.54± 146.79 ms vs 584.81± 145.82 ms, P = 0.835).Conclusion: The dysfunction of cerebellar functional connectivity in specific brain regions may be one of the pathological and physiological causes of cognitive impairment of ADHD.Keywords: attention deficit hyperactivity disorder, cerebellum, children, functional connectivity, resting-state functional magnetic resonance imaging
