The relationship between cognitive function and the enlargement of peripheral vascular space in patients with acute ischemic stroke / 中华行为医学与脑科学杂志

ABSTRACT

Objective:To investigate the relationship between the enlarged of peripheral vascular space and cognitive function in patients with acute ischemic stroke.Methods:Totally 223 patients with first-episode acute cerebral infarction were selected from the department of neurology in Hebei general hospital from September 2016 to December 2018, who completed the test of cognitive function. All patients were divided into cognitive impairment group( n=67)and normal cognitive group( n=156)according to the score of MoCA.The risk factors of cognitive function and the relationship between the enlargement of perivascular space and cognitive function were analyzed by SPSS 21.0. Results:Age, history of coronary heart disease, Hcy, Fib, BG-EPVS and CSO-EPVS were statistically significant different in cognitive impairment group and normal cognitive group(all P<0.05). Age ( B=0.067, OR=1.070, 95% CI=1.035-1.106, P<0.05), Hcy( B=0.032, OR=1.033, 95% CI=1.007-1.060, P=0.013), and BG-EPVS( B=0.720, OR=2.055, 95% CI=1.041-4.055, P=0.038)were independent risk factors for cognitive impairment.The degree of BG-EPVS in the cognitive impairment group was negatively correlated with the total MoCA score( r=-0.332, P<0.05), visual space and execution( r=-0.256, P<0.01), attention( r=-0.256, P<0.01), language( r=-0.182, P<0.05)and orientation( r=-0.370, P<0.05). Conclusion:EPVS, especially BG-EPVS, can be used as an indicator to evaluate the early cognitive function of AIS patients.
