Abstract

Background: Healthy people have a leftward spatial attentional bias, called pseudoneglect. Individuals with end-stage renal disease (ESRD) who are receiving hemodialysis often demonstrate an increase in their leftward spatial attentional bias. Whereas a successful kidney transplant often improves the cognitive functions of individuals who previously received hemodialysis, the effect of a kidney transplant on this abnormal allocation of spatial attention has not been investigated. Objective: To investigate the effects of kidney transplant on individuals who were being treated with dialysis and had an increase in their left spatial attentional bias. Method: The performance of 20 hemodialyzed individuals with ESRD on the line bisection test was compared to that of 17 demographically matched individuals with ESRD, who had received a kidney transplant, and 23 demographically matched healthy controls (HC). Results: All of the participants exhibited a left spatial bias on the line bisection task. When compared with the HC, the hemodialyzed individuals demonstrated a significantly greater left spatial bias. There was, however, no difference in spatial bias between the HC and the individuals who had received a kidney transplant. Conclusion: A successful kidney transplant can improve patients’ abnormal leftward allocation of spatial attention. However, future studies are needed to better understand the mechanisms of this spatial attentional bias in hemodialyzed individuals and the normalization of bias following transplantation.

肾移植成功后血液透析患者的左空间注意偏差正常化
背景:健康人有一种向左的空间注意偏向,称为伪忽视。接受血液透析的终末期肾病(ESRD)患者通常表现出向左空间注意偏差的增加。尽管成功的肾移植通常能改善先前接受血液透析的个体的认知功能,但肾移植对这种空间注意力异常分配的影响尚未得到研究。目的:研究肾移植对接受透析治疗且左空间注意偏向增加的患者的影响。方法:将20名血液透析的ESRD患者与17名接受过肾移植的ESRD人口统计学匹配患者和23名人口统计学匹配的健康对照组(HC)在平分线测试中的表现进行比较。结果:所有参与者在直线平分任务中都表现出左空间偏向。与HC相比,血液透析的个体表现出明显更大的左空间偏差。然而,HC和接受肾移植的个体之间的空间偏差没有差异。结论:成功的肾移植可以改善患者空间注意力的异常向左分配。然而,需要未来的研究来更好地了解血液透析患者这种空间注意偏差的机制,以及移植后偏差的正常化。

期刊介绍: Cognitive and Behavioral Neurology (CBN) is a forum for advances in the neurologic understanding and possible treatment of human disorders that affect thinking, learning, memory, communication, and behavior. As an incubator for innovations in these fields, CBN helps transform theory into practice. The journal serves clinical research, patient care, education, and professional advancement. The journal welcomes contributions from neurology, cognitive neuroscience, neuropsychology, neuropsychiatry, and other relevant fields. The editors particularly encourage review articles (including reviews of clinical practice), experimental and observational case reports, instructional articles for interested students and professionals in other fields, and innovative articles that do not fit neatly into any category. Also welcome are therapeutic trials and other experimental and observational studies, brief reports, first-person accounts of neurologic experiences, position papers, hypotheses, opinion papers, commentaries, historical perspectives, and book reviews.
