Abstract
Generally, dementia is defined as a general term for sustainable decline of memory, language and
other thinking abilities, therefore, the early detection is important. However, it is often failed
because it is difficult to articulate dementia problem verbally. In this paper, from the perspective
of narrative approach, I analyzed semi-structured interview data stored in DIPEx-Japan, a
database of individual experiences of health and illness, and discussed the difficulty of early
detection of dementia. I concluded the importance of narratives without specific events because
they are less influenced by cognitive bias.
