Data were presented with mean (standard deviation). Group comparisons: independent T test (age, education, MMSE, MoCA, and CDR), gender (chi-square test). MMSE = Mini-Mental State Examination, MoCA = Montreal Cognitive Assessment, CDR = Clinical Dementia Rating. Statistical significance set at P < 0.05
