We investigated emotional regulation of autobiographical memories in Alzheimer's disease (AD). AD patients and control participants were asked to retrieve memories in response to "happy" and "sad" cues. Participants were also asked to rate the emotional valence of memories at retrieval as well as at the moment the events were encoded. Results showed that both control participants and AD patients rated memories cued by "happy" as more positive when retrieved than when encoded. Both control participants and AD patients also rated memories cued by "sad" as less negative when retrieved than when encoded. Furthermore, emotional regulation (i.e., emotional variation across retrieval and encoding of memories) was significantly correlated with depression in AD patients and control participants. These findings suggest a cognitive reappraisal strategy by which AD patients 1) attribute positive meaning to positive memories, and 2) view negative emotional memories from a less negative perspective, demonstrating an ability to re-interpret the meaning of these memories, and thereby, to change their emotional impact. This reappraisal strategy seems to be related with depression as depressive symptoms was inversely correlated with cognitive reappraisal in AD.
我们研究了阿尔茨海默病（AD）患者自传体记忆的情绪调节。AD 患者和对照组参与者被要求根据“快乐”和“悲伤”提示检索记忆。参与者还被要求在检索时以及事件编码时对记忆的情绪效价进行评分。结果表明，对照组参与者和 AD 患者在检索时对“快乐”提示的记忆的评价比编码时更为积极。对照组参与者和 AD 患者在检索时对“悲伤”提示的记忆的评价也比编码时更为消极。此外，情绪调节（即检索和编码记忆时的情绪变化）与 AD 患者和对照组参与者的抑郁程度显著相关。这些发现表明，AD 患者采用了一种认知重评策略，即 1）对积极记忆赋予积极意义，2）从较不消极的角度看待消极情绪记忆，从而能够重新解释这些记忆的意义，并改变其情绪影响。这种重评策略似乎与抑郁有关，因为 AD 患者的抑郁症状与认知重评呈负相关。
