Abstract:
Objective:To investigate the correlation between global burden of small vessel disease(CSVD) on MRI and impaired spatial navigation in patients with CSVD.Methods:Patients with CSVD admitted to the Department of Neurology, Nanjing Jiangning Hospital from November 2020 to June 2022 were selected as the research subjects. The global burden of CSVD was scored according to the head MRI findings, and was divided into mild group (0-1 points), moderate group (2 points), and severe group (3-4 points). All patients were tested for spatial navigation function. Multivariate linear regression model was used to analyze the correlation between the global burden of CSVD and the spatial navigation function.Results:A total of 101 patients with CSVD were enrolled, including 37 patients in the mild group (36.6%), 28 in the moderate group (27.7%), and 36 in the severe group (35.6%). Age, glycosylated hemoglobin, total cholesterol, low-density lipoprotein cholesterol and creatinine, as well as the proportions of hypertension, diabetes, previous stroke or transient ischemic attack in the moderate group and the severe group were significantly higher than those in the mild group, while the high-density lipoprotein cholesterol was significantly lower than that in the mild group (all P<0.05). The spatial navigation function test showed that the environment + self-navigation, self-navigation and environment navigation functions of the moderate group and the severe group decreased significantly compared with the mild group (all P<0.05). Multivariate linear regression analysis showed that after adjusting for age, sex, hypertension, previous stroke or transient ischemic attack history and years of education, the global burden of CSVD and environment + self-navigation ( β=0.518, P<0.001), self-navigation ( β=0.481, P<0.001) and environmental navigation ( β=0.699, P<0.001) function had significant correlation. Conclusion:The global burden of CSVD is correlated with spatial navigation functions.
