Abstract: Objective To explore the characteristics of prospective memory (PM) in the elderly patients undergoing maintenance hemodialysis (MHD), and to explore the influencing factors. Methods A total of 60 elderly patients in Blood Purification Center of Zhongda Hospital were enrolled as the MHD group, and 60 elderly community residents matched by age who did not receive MHD were enrolled as the control group. All subjects in the two groups underwent the neuropsychological assessments, including Mini-Mental State Examination (MMSE), verbal fluency test (VFT), digital span test (DST), Rey auditory verbal learning test (RAVLT), Stroop color-word test (SCWT), event-based prospective memory (EBPM) and time-based prospective memory (TBPM). Results There was no significant difference in the DST score between the two groups (P>0.05). However, compared with the control group, the MMSE score was lower (P<0.01), SCWT reaction time was longer, RAVLT and VFT (fruit) scores were lower, EBPM and TBPM scores were lower, and the number of clock checking was significantly lower in the MHD group (P<0.01). Conclusions EBPM and TBPM are impaired in the elderly MHD patients. PM assessment may be useful in screening cognitive impairment and improving the treatment compliance and prognosis.
