MMSE, Mini–Mental State Examination; MoCA, Montreal Cognitive Assessment; STM, short–term memory; ARWMC, Age–related white matter change; MARS, Microbleed anatomical rating scale; PVSE, enlargement of the perivascular space; CS, centrum semiovale; BG, basal ganglia; ICH, intracerebral hemorrhage; CAA, cerebral amyloid angiopathy; SVD, small vessel disease.

Spearman's rank correlation coefficient was calculated to explore correlations between variables. Dark gray block: moderate-to-strong correlation, 0.6 ≤ |r_s|. Light gray block: fair correlation, 0.3 ≤ |r_s| <0.6.
