The Cohort Study of Cognitive Impairment in Chinese Hemodialysis Patients

This study is going to apply neuropsychological battery tests to measure cognitive function across multiple cognitive domains in our cohort of 600 maintenance hemodialysis patients and evaluate: 1. The presence and patterns of cognitive impairment in domains of executive function, perceptual-motor function, language, learning and memory, and complex attention; 2. Clinical characteristics of participants with and without cognitive impairment; 3. the risk factors which might be related to cognitive impairment in this group of population; 4. The association between cognitive impairment and all-cause mortality, stroke and non-fatal cardiovascular events; We hypothesize that hemodialysis patient is going to have cognitive impairment which might be associated with some risk factors. We also anticipate that cognitive impairment might have some kind of association with the clinical outcomes like all-cause mortality, stroke and other common clinical outcomes that we mentioned above.
