NEFL and frontotemporal dementia: Cross-sectional NfL correlated with the BNT (table 2, figure 3A, rs=−0.32, p=0.002), trended towards an association with annual change of MMSE (table 3, uncorrected p=0.04), but not with age, disease duration at CSF collection, cross-sectional MMSE, CDR-SB or FTD-CDR-SB.
