Vascular dementia (VaD) is a dementia syndrome produced by vascular damage to the brain and increases in incidence with ad-vancing age. Early Identification and diagnosis of VaD is particularly importent since its course may be modifiable through control-ling vascular risk factors. VaD is heterogeneous and consists of several syndromes : multi-infarct dementia, strategic single infarcts dementia, and subcortical vascular dementia. The diagnosis of VaD is based on several features 1) dementia, 2) evidence of cere-brovascular disease, and 3) temporal relationship between dementia and cerebrovascular disease. Treatment of VaD includes control of vascular risk factors, prevention of further vascular injury and treatment of cognitive impairment. Cholinesterase inhibitors pro-vide symptomatic benefits in treatment of VaD.
