The classification of covert cerebral small vessel disease (SVD) SVD type 1 = isolated white matter hyperintensities (WMH; ≥ 50th WMH volume/total intracranial volume ratio in the total population = 0.7 × 10− 3); SVD type 2 = WMH with lacune(s) but without cerebral microbleed (CMB); SVD type 3 = mixed CMB; SVD type 4 = strictly-lobar CMB.
