- W2947142200 abstract "Background Sleep deprivation causes a number of negative effects on cognitive functions. It disturbs the processes of attention and concentration. It reduces visual vigilance and reduces the ability to recognize complex visual information. The aim of our study was to determine the effect of 48 hours sleep deprivation on visual processes evaluated with visual evoked potentials Material and methods We examined 17 healthy volunteers aged from 21 to 24 years old, 7 men and 10 women who underwent controlled sleep deprivation for 48 hours. Basic vital parameters were monitored in all subjects. Visual evoked potentials were induced before and after 24 and 48 hours of sleep deprivation. The study was approved by the local bioethics committee. All participants gave written consent to participation in the study. Latencies and amplitudes of N75, P100 and N145 responses were analyzed. Results No significant differences in the N75 and P100 latencies and amplitudes were found. N145 response latencies were significantly longer after 24 and 48 hours of sleep deprivation. Conclusions 24 and 48 hours sleep deprivation induces prolongation of the N145 response, which may be a neurophysiological biomarker of visual perception disturbances in sleep deprivated persons." @default.
