Abstract

Chronic kidney disease (CKD) is a condition in which damaged kidneys cannot properly filter blood throughout the body. This results in excess fluid and waste products to remain in the bloodstream, which can lead to other health complications if not treated. Kidney failure occurs when an individual has 10-15% of optimal kidney functioning, resulting in toxic levels of waste in the bloodstream. Recent literature has demonstrated that individuals receiving dialysis have poorer cognitive functioning compared to the general population, especially in regard to executive functioning. The purpose of the current study was to identify the executive functioning abilities in a sample of kidney dialysis patients and to determine the feasibility of conducting neuropsychological assessments within a dialysis clinic setting. Preliminary data from a small sample revealed that, overall, participants did not demonstrate clinically significant deficits in subjective or objective executive functioning abilities. However, two clinically noteworthy profiles were analyzed. Findings also suggested that the use of the BRIEF-A and the TMT, Parts A and B, are feasible and useful within a dialysis clinic. Clinical implications are discussed and include the need for a behavioral health presence in dialysis clinics and routine neuropsychological testing. Additional implications regarding the impact of cognitive impairment on medical adherence are also discussed.
