Subjects who meet the entry criteria and agree with participation among visitors to clinical sites in this trial from April 2016 to the end of March 2023 will be included in this trial. The onset status of dementia (including Alzheimer's disease) of the subjects will be followed for 3 years (for subjects of mild cognitive impairment) after blood collection and measurement of plasma-free amino acids at the baseline.
