dc.description.abstractObjective: The effects of sleep deprivation on cerebral metabolism and blood flow have been investigated using different methods. To evaluate cerebral blood flow (CBF) changes and reactivity using transcranial Doppler (TCD) sonography in response to visual stimulation before and after sleep deprivation.Materials and Methods: The study included twenty healthcare professionals. For each cerebral hemisphere, the flow velocities of the two posterior cerebral arteries (PCA) were measured using TCD with eyes closed before and after sleep deprivation. Again, before and after sleep deprivation, visual stimulation was given with eyes open and flow velocity in PCA was recorded. The visual reactivity value was calculated for the right and left hemispheres before and after sleep deprivation. Reactivity is calculated as relative changes in blood flow velocity [?BFv = 100*( Vs-Vr)/Vr].Results: It was found that CBF velocity increased significantly in response to visual stimulus before and after sleep deprivation in the right and left hemispheres (p<0.001).In both hemispheres, CBF velocities measured after sleep deprivation without visual stimulus increased compared with those measured before sleep deprivation, but this increase showed statistical significance only for the right hemisphere (p=0.008). It was observed that the visual reactivity value calculated after sleep deprivation from the right and left hemispheres significantly decreased compared with that before sleep deprivation (p<0.001).Conclusion: We found that visual reactivity values in healthcare professionals were significantly reduced after sleep deprivation. This decrease in visual reactivity value may cause decreased attention and prolongation of reaction time in healthcare professionals.en_US
