Reduced kidney function is linked to an increased risk of dementia. In people with a normal kidney filtration rate of 90 to104 mL per minute, there were seven cases of dementia per 1,000 person-years. Incidence rates (IR) of dementia were progressively higher with lower estimated glomerular filtration rate (eGFR): from 6.56 per 1,000 person-years in persons with eGFR of 90 to 104 milliliters (ml) per min; to 30.28 per 1,000 person-years in those with eGFR less than 30ml per minute. Chronic kidney disease occurs when a person’s kidneys progressively lose their . . .
