VCI: vascular cognitive impairment; VH: visual hallucination; : number of cases; NA: not applicable; NS: nonsignificance; MTA: medial temporal lobe atrophy; OR: odds ratio. Adjusted ORs of variables were ORs adjusted for age, gender, and disease severity by Clinical Dementia Rating scale. Cerebral microbleeds in MRI T2 gradient imaging among 94 VH+ and 760 VH−.
