Magnetic Resonance Imaging Cerebrovascular Disease by Age Decade

Age Group, yr	No.	Silent Brain Infarcts	Cerebral Microbleeds	WMH, cm3
40–49	143	2.8%	2%	1.1 (0.7–1.9)
50–59	324	5.9%	2.5%	1.3 (0.8–2.4)
60–69	262	11.5%	9.5%	2.2 (1.3–3.8)
≥70	74	18.9%	8.1%	4.3 (1.8–9.6)

WMH is displayed as median (interquartile range). All p < 0.001 for comparisons by age.

WMH = white matter hyperintensity.
