  1. Because of missing information of possible confounders, these multiple group analyses were analyzed by using 537 participants in 70s and 518 in 80s in Model 1, and 482 in 70s and 483 in 80s in Model 2
  2. aModel1 adjusted for sex and MoCA-J score
  3. bModel2 adjusted for sex, MoCA-J score, Body Mass Index, histories of stroke and heart disease, economic condition, education, hypertension, dyslipidemia, and diabetes
  4. cEquality constrained model was constrained with equality constrained across age groups
