A total of 558 individuals returned for a re-examination of eGFR (75% response rate, age 76 [76; 77] years, 48% males, 76 new cases of CKD). Participants with CKD had higher P-NfL levels than those with normal kidney function (median; 18.8 vs 14.1 pg/mL, p < 0.001), while MRI and CSF markers were similar between the groups. P-NfL was independently associated with CKD after adjustment for confounding variables, including hypertension and diabetes (OR; 3.231, p < 0.001), in a logistic regression model. eGFR and CSF Aβ 42/40: R = 0.23, p = 0.004 correlated in participants with Aβ42 pathology. P-NfL levels in the highest quartile were associated with incident CKD at follow-up (HR; 2.39 [1.21: 4.72]).Discussion In a community-based cohort of 70-year olds, P-NfL was associated with both prevalent and incident CKD, while CSF and/or imaging measures did not differ by CKD status. Participants with CKD and dementia presented similar levels of P-NfL.Aβ=β-amyloid; AD=Alzheimer disease; BMI=body mass index; CDR=clinical dementia rating; CKD=chronic kidney disease; COPD=chronic obstructive pulmonary disease; CRP=C-reactive protein; eGFR=estimated glomerular filtration rate; HDL=high-density lipoprotein; LDL=low-density lipoprotein; LP=lumbar puncture; NfL=neurofilament light protein; P=plasma; p=phosphorylated; t=total
