Exclusion criteria

Exclusion criteria: Healthy subjects Those with a history of or complications from neurological diseases Those who have performed MMSE or MoCAJ within 6 months Those with mental illness Those who are taking medication that may affect EEG measurement Those with severe complications (malignant tumor, myocardial infarction, heart failure, etc.) that may affect the amyloid beta PET CT test and EEG measurement Those whose physician judges that it is difficult to perform amyloid beta PET CT test due to some physical conditions (e.g., allergy to flutemetamol (18F)) Those who, for some reason (frontal trauma, frontal skin disease, skull defect, blindness, etc.), are considered to have difficulty in performing EEG measurement and tasks during EEG measurement Pregnant women, nursing mothers, and those who wish to become pregnant during the research period Those who are participating in other research.
