All participants completed the Mini-mental State Examination and Attention Deficit Hyperactivity Disorder rating scale. We acquired 32-lead electroencephalography (EEG) data while participants performed the ANT, followed by Polysomnography.Results: Of the 87 children, 21 had no OSA, 49 had mild OSA, and 17 had moderate to severe (MS) OSA. Each group had similar questionnaire scores, similar response time and accuracy for the different ANT conditions. There are alterations in the processing of three separate components of the attentional network in children with OSA. The amplitude of the N3 component at the FZ electrode in the MS OSA group was lower than that of the non-OSA and mild OSA groups (all P< 0.05). In the executi control network phase, the energy of alpha band was higher in the MS OSA group than in the mild OSA group (Z=− 2.624, P=0.026). The mean amplitude of the N3 component at the FZ electrode was correlated with the obstructive apnea-hypopnea index (OAHI) (r=0.232, P=0.038).Conclusion: Attention impairment was observed as a reduced N3 in the frontal area in the MS OSA group, which was correlated with the OAHI. However, questionnaire and behavioral performance did not differ significantly between groups. These findings suggest that the N3 amplitude is a sensitive neuroelectrophysiological marker of OSA-related cognitive impairment.Keywords: OSA, child, attention, event-related potential, time-frequency
