Abstract:
Aims: Unlike autobiographical memory (i.e., memory for personal information) in Alzheimer’s
Disease (AD), little is known about Self-Defining Memories (SDM) (i.e., memories of highly
significant personal events) in AD.
Methods: The characteristics of self-defining memories in AD were evaluated by analyzing their specificity,
emotional valence, and integration, as well as their centrality and contribution to self-continuity.
Results demonstrated fewer specific SDM in AD participants than in controls.
Results: No significant differences were observed between AD participants and controls regarding the
production of positive or integrated SDM. Furthermore, no significant differences were observed between
AD participants and controls regarding the rating of the centrality of SDM and their contribution
to self-continuity. These results demonstrate that, although AD participants produce fewer specific SDM
than controls, both populations have similar levels of emotional valence, integration, centrality, and selfcontinuity
of these memories.
Conclusion: It is concluded that patients with AD, at least those in the mild stages of the disease, can
build on significant personal events and experiences (i.e., SDM) to reflect on how these events have
changed the way they see themselves.
