Vascular cognitive impairment(VCI) encompasses the entire range of cognitive deficits associated with cerebrovascular disease(CVD), from mild deficits with little or no functional impairment, such as vascular cognitive impairment-no dementia(VCIND), to full-blown vascular dementia(VaD). Accurate diagnosis of vascular cognitive impairment is important but may be difficult. In this review we report advances in VCI in the following areas: etiology, subtypes, neuropsychology, biomarkers, neuroimaging, and diagnostic criteria.
