Event-related potential study on vigilant attention in children with sleep disordered breathing
Objective To explore the vigilant attention function and behavioral changes in sleep disordered breathing(SDB)children.Methods Thirty SDB children(SDB group)and 30 normal children(control group)were selected from June 2022 to August 2023.All participants underwent continuous per-formance test(CPT-AX)(Go/Nogo)and behavioral test.The latency and amplitude of contingent negative variation(CNV)components under cue/uncue conditions in leads F3,Fz and F4 were measured.The t-test and Mann-Whitney U test were used to conduct statistical analysis by SPSS 25.0 software.Results(1)There were no statistically significant differences in the number of correct responses,reaction time and num-ber of false alarms between the SDB group and the control group(all P＞0.05).(2)The latencies of cue-CNV in the SDB group(F3:618.00(582.50,644.50)ms,Fz:603.00(579.50,634.00)ms,F4:(606.87±25.07)ms)were longer than those in the control group(F3:(508.47±25.82)ms,Fz:502.00(470.00,520.50)ms,F4:514.00(487.00,536.50)ms)in leads F3,Fz and F4.The latency of cue-CNV of lead F4 in the SDB group was higher than that in the control group,and the difference was statistically significant(P＜0.05).The latencies of uncue-CNV in lead F3 and Fz in the SDB group were higher than those in the control group,and the differences were statistically significant(both P＜0.05).Conclusion SDB children have shown activation in the right brain area during attentional tasks,and the prolonged CNV latency may be a sensitive neuroelectrophysiological marker for early clinical assessment of vigilant attention dysfunction.
