Statistics: Correlation analyses revealed significant associations between accumulating cSVD burden and decreased performance on all cognitive domains (all p ≤ 0.001). Results remained significant for information processing speed (r = −0.181, p = 0.013) and overall cognition (r = −0.178, p = 0.017), after correction for age and sex. Testing of trend using linear regression analyses revealed the same results.
