				        	Objective To investigate the relationship between the level of serum cystatin C (CysC) and cognitive function in patients with acute cerebral lacunar infarction caused by small vessel disease . Methods One hundred twen-ty-three patients with acute cerebral lacunar infarction were divided into 3 groups according to serum cystatin C level. Patients were further divided into normal group (n=64), vascular mild cognitive impairment (VaMCI) group(n=36),and vascular dementia( VaD) group (n=23). The CysC, estimated glomerular filtration rate (eGFR), serum creatinine (Scr), TC, TG, HDL, LDL, fast glucose, HbA1C, NIHSS, MMSE, ADAS-cog score were compared between the 3 groups. Multivari-able logistic regression analysis was used to examine the association of serum CysC with cognitive function. Results Sub-jects with higher CysC levels tended to have lower MMSE score(21.98 ± 6.08 vs. 25.02 ± 4.69 vs. 25.10 ± 3.95 )and higher ADAS-cog score(17.73±14.23 vs. 12.51±10.39 vs. 10.67±7.53). The higher CysC was, the higher SCr and lower eGFR were. Subjects with severer cognition impairment tended to have higher CysC(0.93 ± 0.21 vs. 1.10 ± 0.45 vs. 1.34 ± 0.58). Multivariable logistic regression showed the regression coefficient was 7.06(P<0.05). Conclusion Elevated Serum CysC is one of the risk factors of cognitive dysfunction and associated with the severity in patients with small vessel disease-re-lated acute lacunar cerebral infarction.
