Baseline CSF measures of SNAP-25 and SNAP-25/Aβ42 as predictors of conversion from MCI to AD. Survival from AD as a function of CSF SNAP-25 (a) and SNAP-25/Aβ42 (b) measures (dichotomized at the median values) are shown. Analyses were adjusted for age and gender. Cutoff values were 5.4 pg/ml and 0.037 for SNAP-25 and SNAP-25/Aβ42, respectively. Aβ amyloid-β, AD Alzheimer’s disease, SNAP-25 synaptosomal-associated protein 25
