The association of APOE genotypes with cerebral microbleeds (CMBs) was examined on the basis of the location of CMBs in 414 patients who were admitted primarily because of stroke. With respect to possession of the epsilon2 or epsilon4 allele, the adjusted odds ratio was 1.94 (1.05 to 3.58) for lobar CMBs but 1.21 (0.69 to 2.11) for nonlobar CMBs. This suggests that the pathogenesis of CMBs may differ depending on their location.
