Fig. 4.

This figure qualitatively compares the vascular factors (WMH volume and PSMD), the Alzheimer's factors (Aβ Ratio and pTau), and the cognition outcome measures (executive and the memory function) for the HC and the LA group in the top row and the four patient groups (LA, AD, SIVD, and MX) in the bottom row. The top row shows the similarity of LA and the healthy control group. The bottom row shows that the MRI biomarkers group AD and LA together, while the CSF biomarkers groups AD and MX together. Memory is lower in AD and MX subjects, while the executive function is lower in SIVD subjects. In the patient groups, each pair of variables is significantly correlated to the other variable. Spearman correlations and their significance is indicated.
