The prevalence of CMBs in Lewy body disease with cognitive impairment. The prevalence of CMBs in MCI-LB, DLB, PD-MCI and PDD were shown by proportions (column) with 95%CI (error bars), and there was significant difference among the four groups (p = 0.019). When the four groups were compared separately, the prevalence of CMBs was significantly higher in the DLB group than in the PD-MCI group after Bonferroni correction (p = 0.005). CMBs, cerebral microbleeds; MCI-LB, mild cognitive impairment with Lewy bodies; PD-MCI, Parkinson’s disease with mild cognitive impairment; DLB, dementia with Lewy bodies; PDD, Parkinson’s disease dementia
