Scatter plots presenting Pearson’s correlations between CSF levels of NFL and verbal episodic memory (a, b), T-tau and verbal episodic memory (c, d), GFAP and processing speed (e, f), and GFAP and executive functions (g, h) within the whole cohort and by CSF profile. *Cognitive domains were adjusted for covariates (age and education). Without the bottom corner GFAP outlier in the CSF AD profile group, Pearson’s correlations were slightly lower for f processing speed (r = − 0.58, p = 0.001) and h executive functions (r = − 0.28, p = 0.15)
