Prevalence and clinical implication of microbleeds in dementia with lewy bodies in comparison with microbleeds in Alzheimer's disease.

Background: Cerebral microbleeds (MBs) have been well investigated in Alzheimer's disease (AD), but not very extensively in non-AD dementias or in dementia with Lewy bodies (DLB).

Aims: To elucidate the clinical significance of MBs in DLB.

Methods: We compared the prevalence, locations and risk factors for MBs in 59 DLB and 81 AD patients.
