New research published in the journal American Society of Nephrology suggests that both short- and long-term haemodialysis may be associated with brain injury.
Researchers at the University of Glasgow studied patients with end-stage kidney disease who were undergoing haemodialysis over a period of 12 months (n=97). Cerebral blood flow and cognitive function were assessed during and out-with dialysis.
The findings showed that blood flow to the brain reduced during dialysis with a subsequent decrease in the cognitive function. Those who remained on dialysis had an increased risk for progressive brain injury. However, individuals who received a transplant and discontinued dialysis witnessed improvements in memory and verbal learning functions.
Dr. Mark Findlay from the University of Glasgow's Institute of Cardiovascular and Medical Sciences said: "Based on our findings it would appear that early recognition of those patients most at risk may help to limit their brain injury, which appears potentially reversible by kidney transplant."
