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.

目的：与阿尔茨海默病 (AD) 中的自传体记忆 (即个人信息记忆) 不同，对 AD 中的自我定义记忆 (SDM)（即对非常重要的个人事件的记忆）知之甚少。

方法：通过分析自我定义记忆的特异性、情感效价和整合性，以及它们的中心性和对自我连续性的贡献，评估 AD 中自我定义记忆的特征。结果表明 AD 参与者的特定 SDM 少于对照组。

结果：在阳性或综合 SDM 的产生方面，在 AD 参与者和对照组之间没有观察到显着差异。此外，关于 SDM 的中心性评级及其对自我连续性的贡献，在 AD 参与者和对照组之间没有观察到显着差异。这些结果表明，虽然 AD 参与者产生的特定 SDM 比对照组少，但两个人群的情绪效价、整合、中心性和这些记忆的自我连续性水平相似。

结论：得出的结论是，AD 患者，至少是处于疾病轻度阶段的患者，可以基于重要的个人事件和经历（即 SDM）来反思这些事件如何改变了他们看待自己的方式。
