The study, which looked at almost patients using dialysis, measured cerebral blood flow and tested each patient's cognitive function during and out-with dialysis. The researchers found that blood flow to the brain was reduced during dialysis and that patients' cognitive function was also decreased as well. The study also found that those patients who remained on dialysis were more at risk of progressive brain injury due to reduced blood flow during the procedure. Crucially, however, those who had a transplant and stopped dialysis saw an improvement in memory and verbal learning brain functions.
While cognitive impairment is commonly seen in this patient group, until now scientists didn't know exactly why this occurred. As a result of this study, researchers now believe reduced blood flow to the brain during dialysis, leading to cerebrovascular disease in the long term, may be the cause.
Professor Patrick Mark, Professor of Nephrology at the University of Glasgow, said: "This is an important study which we believe supports the current hypothesis that dialysis is associated with progressive brain injury. Crucially we found that while patients both on short and long term dialysis treatment has some form of cognitive impairment , patients who went on to receive a transplant saw an improvement in their white matter and in their memory.
The frequency of cerebrovascular disease is also 10 times more common in patients with end stage renal disease than those in the general population. Mark Findlay, from the University'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. The researchers studied patients with end stage renal disease who were undergoing hemodialysis over a 12 month period.
The researchers also used MRI scanning to assess any white matter injury to patients' brains. The paper, "Investigating the relationship between cerebral blood flow and cognitive function in hemodialysis patients' is published in the Journal American Society of Nephrology. Explore further.

Home hemodialysis HHD requires that two needles be inserted into the patient's vascular access to allow the blood to flow from the body to the machine and back into the body. Patients on HHD are trained to insert their own needles or to have their care partners insert the needles.
While learning to self-cannulate may seem a little daunting at first, new techniques, such as the buttonhole technique, have made self-cannulation much easier and more comfortable.
Patients using the buttonhole technique insert their needles into the same spot each time they do dialysis. This causes the insertion points to form scar tissue and creates a hole much like the hole in a pierced ear.

With this method, patients are able to use blunt needles instead of sharp needles, which are more comfortable and safer for the patient. It's important to note, though, that the buttonhole technique requires that a patient have a fistula, which is created by connecting an artery to a vein using your own tissue.
Patients who self-cannulate generally have a better chance of keeping their vascular access healthy and functioning for a long period of time. Patients who learn to self-cannulate often report that inserting their needles is not as difficult as they expected. In addition, once they learn to self-cannulate, most patients rarely want anyone else to cannulate for them.

Home hemodialysis HHD patients and their care partners will go through a comprehensive safety and training program at a local dialysis center. During the training program, they will learn everything they need to know about performing hemodialysis treatments safely and effectively in their homes.

Patients and their care partners will learn how to self-cannulate, operate the dialysis equipment, create a clean environment, record treatments on a log and handle needles and other supplies. Training usually takes from four to eight weeks and is conducted individually by a home training nurse. The training material is customized to the patient's medical needs and equipment choice.
Patients and their care partners start out by observing the training nurse during the dialysis process. As they learn more about the process, patients and care partners will begin assisting the training nurse, and they will continue to take on more responsibility until they are doing it on their own. In addition, the new machines are designed to require fewer supplies and less storage space within the patient's home. One of the new machines is also small and portable, making it possible for dialysis patients to travel while on dialysis. Your doctor can help you decide which machine is right for you.
Home hemodialysis is a safe and effective option for end stage renal disease ESRD patients who want to receive the care they need while maintaining the freedom they value. It is an at-home option that gives patients control over when and how they dialyze, which can dramatically improve their overall quality of life. In addition, patients who dialyze at home have the ability to achieve improved clinical outcomes.
