Inclusion criteria

Inclusion criteria: 1) Those who have cognitive impairment suspected of having MCI and early AD based on the diagnostic criteria of NIA-AA or DSM-5 2) 40 to 90 years old, regardless of gender 3) A person who can obtain written consent from the person or his / her substitute. 4) MRI imaging including 3DT1 weighted image has already been performed within 90 days at the time of obtaining consent.

Exclusion criteria

Exclusion criteria: 1) Those who have gross lesions (brain tumor, cerebral vascular malformation, cortical infarction, etc.) on brain MRI. 2) Those who have serious complications, or those who have a history of these and are judged by the investigator and the investigator to be ineligible for this study. 3) In addition, those who are judged by the principal investigator and the investigator to be ineligible for this study.

Design outcomes

Primary
