RESUMEN
Objective To investigate the correlation between the severity of subcortical ischemic lesions and vascular cognitive impairment in encephalorrhagia patients. Methods One hundred and twenty-four encephalorrhagia patients were enrolled into two groups, the normal cognition group (60 cases, without cognitive impairment) and the cognitive impairment group (64 cases, with vascular cognitive impairment). Parameters of the lesion diameters, various lesion locations, white matter lesions severity and NIHSS scale score, modified Bathel index score were compared between these two groups. The correlations between the above indexes and the vascular cognitive impairment degree were analyzed by Logistic regression proceduress. Results Compared to the normal cognition group, the indexes of lesion number of frontal area and basal ganglia, lesion diameters, white-matter severity and NIHSS scale score of cognitive impairment group were higher (P0.05, respectively) in the cognitive impairment group. Result of Logistic regression analysis showed a positive correlation between the severity of white-matter and the degree of vascular cognitive impairment (OR =4.705, P=0.009). Conclusion The severity of white-matter can effectively assess the degree of vascular cognitive impairment of encephalorrhagia patients.
