Glasgow scientists have discovered a link between kidney dialysis and progressive brain injury in those who receive the treatment for many years.

Research done at Glasgow University found that the process can cause short term "cerebral stunning" and found that short and long term hemodialysis is associated with brain injury.

Dialisys is life changing for many patients awaiting a kindey transplant or not suitable for a transplant.

The study, which looked at almost 100 patients using dialysis, measured cerebral blood flow and tested each patient's cognitive function during and outwith dialysis.

The researchers discovered that patients' cognitive function was decreased during dialysis as well as blood flow to the brain.

The study also found those patients who remained on dialysis were more at risk of progressive brain injury due to decreased blood flow to the brain during the procedure.

Crucially, however, those who had a transplant improved in memory and verbal learning brain functions.
