Vascular dementias, VD, are dementias due to cerebrovascular lesions. Subgroups of VD include multi-infarct dementia, single infarct (or strategic infarct) dementia, subcortical ischemic vascular dementia, hemorrhagic dementia, hypoperfusion dementia. VD are also related to post-stroke dementia, mixed Alzheimer's disease and vascular dementia and vascular cognitive impairment. These various entities allow to characterize more homogenous subgroups within the heterogeneous group of vascular dementias. However, ambiguities in their definitions, associated with frequent overlaps as well as lack of consensual definition for mixed dementia limit both their theoretical value and use in clinical practice. The diagnosis of cerebrovascular diseases should be dissociated from that of dementia, which could be associated with other pathologies.
