Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Cognitive tasks using a tablet device, stool sample collection, and brain activity measurement with a handheld NIRS device (for those who wish to participate) will be conducted from one to a maximum of six times, at intervals of 30 or 90 days. Each cognitive task will be performed over two days per session. During breaks between tablet-based cognitive tasks, participants will complete the Japanese versions of the POMS Short Form and MoCA. Participants who consent to wearing a smart ring or smartwatch will wear the device as much as possible throughout the study period. Data will be provided via the participant's smartphone. | — |
