ZHANG Nan.Department of NeurologyTianjin Medical University General HospitalTianjin 300052China

    Abstract  Vascular dementia(VaD) is a syndrome characterized with acquired mental retardations due to brain damages of cerebrovascular origincausing 20% to 30% of all the elderly dementia cases.The pathogenesis of VaD involves a series of molecular and structural changes subsequent to cerebrovascular lesionswhich includes inflammatory reactionsoxidative stressapoptosisexcitotoxicity and synaptic transmission impairments.Although clinical trials have been conducted on a number of drugs including cholinesterase inhibitorsmemantinenimodipine and cerebrolysinthere is not a FDA approved drug for treating VaD so farsince the drugs are either with limited effect on ability of daily livingor with uncertain security.The treatment of VaD should be multiple targeted and further clinical trials precisely designed are needed for the effective treatment of VaD.This paper summarizes the pathogenesis and treatment of VaD.
