Abstract:
Objective To investigate the relationship between cerebral atrophy and total burden of cerebral small vessel disease in patients with recent small subcortical infarct(RSSI).Methods A total of 194 elderly RSSI patients admitted to Department of Neurology of Changzhou Second People's Hospital Affiliated to Nanjing Medical University from September 2021 to November 2022 were recruited in this study.All patients completed cranial MRI examination and were divid-ed into a non-mild group 1(97 cases)and a moderate to severe group 1(97 cases)based on the to-tal burden of cerebral small vessel diseases(CSVD)imaging.Visual assessment scale was used to assess the severity of brain atrophy in the whole brain and various regions of the brain.According to the global cortical atrophy scale(GCA)score,all patients were divided into a non-mild group 2(88 cases)and a moderate to severe group 2(106 cases).Brain atrophy in various regions,medial temporal lobe atrophy(MTA)score,frontal temporal lobe atrophy(FTA)score,and posterior cortical atrophy(PA)score were evaluated.Their general clinical and imaging data were collected,multivariate logistic regression analysis was employed to analyze the relationship between GCA score and total burden of CSVD imaging in RSSI patients,and Spearman correlation analysis was further adopted to explore the correlation of GCA score and different parts of brain atrophy with total burden of CSVD imaging.Results When compared with the non-mild group 1,the moderate to severe group 1 had significantly larger proportions of having GCA score of 2-3 points,PA score of 2-3 points,MTA score of 2-4 points and FTA score of 2-4 points(P＜0.01).The ra-tio of having 2-4 points in total imaging burden score of CSVD was obviously higher in the mod-erate to severe group 2 than the non-mild group 2(P＜0.01).Multivariate logistic regression anal-ysis showed that age and total burden of CSVD imaging were independent risk factors for brain atrophy in RSSI patients(OR=1.184,95％CI:1.099-1.276,P=0.000;OR=3.537,95％CI:1.664-7.518,P=0.001).Spearman correlation analysis revealed that the total burden score of CSVD imaging was positively correlated with GCA,MTA,FTA and PA scores in RSSI patients(r=0.518,r=0.382,r=0.471,r=0.388,P=0.000).Conclusion The total burden of CSVD is an independent risk factor for GCA in elderly RSSI patients.The more serious the total burden of CSVD is,the higher the grade of GCA is.The total burden of CSVD is related to the whole brain and brain atrophy in other different regions of the brain.
