Abstract


OBJECTIVE
This study aimed to find the sex differences of the way how educational attainment influence on cognitive function in the mild cognitive impairment patients.
METHODS
A total of 1,704 patients were recruited from a large hospital-based multi-center cohort. Cognitive subdomains were evaluated using the Seoul Neuropsychological Screening Battery-Dementia version. We employed multiple linear regression analysis to compare the score of cognitive subdomains between the groups with high versus low educational attainment based on the high school graduate. Interaction between educational attainment and sex was also included in the analysis
RESULTS
High and low educational attainment group had 41.2% and 58.8% of patients in the study population. In the multiple regression analysis, score of all cognitive subdomains were significantly higher in the high educational attainment group. The score of attention, language, and visuospatial function were also significantly affected by interaction between educational attainment and sex.
CONCLUSION
In the female patients, educational attainment showed higher influence on the attention, language, and visuospatial function score.
