For analysis, Chi-Square test, Fisher’s Exact test and independent t-test, Repeated Measure ANOVA, Contrast test, Repeated Measure ANCOVA, and Wilks’ lambda test were carried out. In result, when senior citizens with mild cognitive impairments took vitamin pills, the blood-homocysteine level continuously reduced in week 4, week 8 and week 12, and cognitive functions continuously increased every week. Such results show that by having senior citizens with mild cognitive impairments orally take vitamin pills, which are relatively cheap and easy to take compared to other methods, it can prevent addition drop in cognitive functions and prevent dementia.
