Objective To discuss the characteristic of syndrome o f Chinese medicine in vascular cognitive impairment（VCI） patients. Methods T he patients of VCI group（107 cases） and normal cognition（NC） group（142 cases） were selected among 774 subjects by neuropsychologic

imaging and biochemical e xamination.Syndromes of Chinese medicine were identified and scored.The risk of different syndromes to VCI was researched. Results Comparing with the NC group

the occurrence ra tes and syndrome scores o f phlegm turbidity clouding the orifices syndrome

stasis obstructing the networ k vessels of the brain syndrome

bowels obstruction and turbidity stagnation syn drome were significantly higher（P<0.05 or P<0.01）

while those of q i and blood deficiency syndrome and exuberant internal heat toxin syndrome were significantly l ower（P<0.05 or P<0.01）.The proportion of single syndrome was highe r in the NC group

while that of multi-syndrome was higher in the VCI group.Co ncerning the risk of different syndromes to VCI

the regression coefficient was 3.472

8.866 and 3.9 21 in phlegm turbidity clouding the orifices syndrome

stasis obstructing the ne twork vessels of the brain syndrome and bowels obstruction and turbidity stagnat ion syndrome respectively（P<0.01）.Conclusion Th e phlegm turbidity clouding the orifices syndrome

stasis obstructing the network vessels of the brain syndrome and bowels obstruction and turbidity stagnation syndrome are more frequent and s evere

which maybe a risk factor to VCI.
