Association of sleep disturbances with cognitive impairment and depression in maintenance hemodialysis patients.

Background: There are few data on the relationship of sleep with measures of cognitive function and symptoms of depression in dialysis patients.

Methods: We evaluated the relationship of sleep with cognitive function and symptoms of depression in 168 hemodialysis patients, using multivariable linear and logistic regression. Sleep disturbances were assessed using the sleep subscale battery of the Choices for Healthy Outcomes in Caring for ESRD (CHOICE) Health Experience Questionnaire.
