Abstract: Objective To compare the neuropsychological performance between vascular cognitive impairment (VCI) and mild cognitive impairment (MCI).Methods The patients were measured by BMDC-NPTB-CR and ADL. The diagnosis of dementia, questionable dementia and normal ability based on the DSM-Ⅳ and the ICD-10 criteria, Hachinski Ischemia Scale, Cornell Scale of Depression in Dementia and the Clinical Dementia Rating.Results VCI group( n =44)had lower scores than MCI group( n =62) in total score(239.33±38.35, 273.90±50.53, P <0.001), language in MMSE(7.29±0.94, 7.76±0.94, P <0.05), WAIS-R score(30.25±4.19, 33.26±6.17, P <0.01), similarities(9.23±2.12, 10.81±2.97, P <0.01), picture completion(9.07±1.77, 10.06±2.60, P <0.05), speed(79.66±25.84, 104.29±22.49, P <0.001), and no significant differences in visuospatial function subtest and total scores of language and central executive, MMSE, memory test.Conclusion The cognitive function is worse in VCI patients than that of in MCI, especially in cognitive speed, abstract thought and language function.
