| Study characteristics | |||
| Patient sampling | All participants were aged 65 and over and were recruited from among attenders at a community dementia care centre in Seoul where people without dementia can request memory testing. Most of the non‐dementia participants were recruited from this centre. AD patients were registered outpatients at Seoul National Hospital but it is not clear whether they had also attended the community dementia care centre. Thus sampling frame is unclear. | ||
