Johns Hopkins: Elderly Patients on Dialysis Have A High Risk of Dementia

Older kidney disease patients who are sick enough to require the blood-filtering treatment known as dialysis are at high risk of dementia, including Alzheimer’s disease, according to a study led by scientists at Johns Hopkins Bloomberg School of Public Health.

The study, published Aug. 9 in the Clinical Journal of the American Society for Nephrology, found evidence that older kidney disease patients had a substantially higher risk of being diagnosed with dementia than community-dwelling older adults.
