Evaluation of the effect of hemodialysis treatment on the spatial distribution of attention in end-stage renal disease patients

Background: We aimed to evaluate the change in attention and concentration after hemodialysis (HD) treatment in patients with chronic renal failure by line bisection test. Material and Method: 40 chronic renal failure patients (17 women, 23 men) with a mean age of 64.65±10.24 who had HD treatment and 40 controls with a mean age of 64.88±10.07 were included in the study. The control group was selected from HD patients with similar demographic characteristics. A line splitting test was performed twice, and just once before the end of HD and immediately after the end of HD. Results: There was no difference between HD patients and controls when analyzing the mean mean score of all lines, before and after dialysis, nor when HD patients were compared with the control group (p=0.348).When separated into short and long lines, there was no difference between the groups either on HD nor after HD on long lines. Conclusion: According to our data hemodialysis procedure doesn’t have any effect on attention. Further testing is needed to test this hypothesis.
