According to a study published in Neurology, lower kidney function is associated with higher levels of Alzheimer’s blood biomarkers in dementia-free adults. The findings suggest that kidney health must be considered when interpreting blood-based tests for Alzheimer’s disease.
The study involved over 2,000 participants with an average age of 72, according to the report. Researchers measured kidney function using estimated glomerular filtration rate (eGFR) and evaluated several key Alzheimer’s biomarkers, including tau proteins, amyloid beta, neurofilament light chain (NfL), and glial fibrillary acidic protein (GFAP).
