Cerebral microbleeds (CMB) represent a common magnetic resonance imaging marker of cerebral small vessel disease, increasingly recognized as a subclinical marker of stroke and dementia risk. CMB detection may reflect the cumulative effect of vascular risk burden and be a marker of higher mortality. We investigated the relation of CMB to risk of death in community dwelling participants free of stroke and dementia.

CMBs may represent the deleterious effect of cardiovascular risk factors in the cerebral vasculature. Although their presence was associated with increased all-cause mortality, the effect was no longer present after accounting for vascular risk factors and preventive treatment use.
