Abstract

Background: While affective disturbances are a key symptomatic indicator of behavioural variant frontotemporal dementia (bvFTD), little is known about how patients process the emotional load of their autobiographical (i.e. personal) memories.

Methods: We assessed the interplay of emotional regulation and autobiographical memory by inviting 18 bvFTD and 20 control participants to remember past personal events. For each memory, participants rated its emotional valence "then" (i.e. when the event has occurred) vs "now" (i.e. when retrieving the event).

Results: Patients with bvFTD described their memories as neutral at both times (p = .85), while control participants rated their memories as more positive during "then" than during "now" (p = .013). Autobiographical retrieval triggered fewer emotional words (p < .001) and less specificity (p < .001) in bvFTD patients compared to control participants.

Conclusions: The lack of significant differences between the emotional characteristics during "then" than "now" in patients with bvFTD (and the flattening of both) may mirror their hampered ability for emotional generation, which may be associated with difficulties in reframing their past experiences to modify and adapt their meaning. The hampered emotional regulation in bvFTD may also be associated with an avoidance strategy and a passive attitude toward the past.

中性过去：行为变异性额颞叶痴呆中自传体记忆的情绪（失调）调节。

背景：虽然情感障碍是行为变异性额颞叶痴呆（bvFTD）的一个关键症状指标，但人们对患者如何处理自传体（即个人）记忆的情感负荷知之甚少。方法：我们通过邀请18名bvFTD和20名对照参与者回忆过去的个人事件来评估情绪调节和自传体记忆的相互作用。对于每个记忆，参与者将其情绪效价评为“当时”（即事件发生时）与“现在”（即检索事件时）。结果：bvFTD患者在这两个时间段的记忆均为中性（p = .85），而对照组参与者认为他们在“当时”的记忆比“现在”的记忆更积极（p = .013）。自传检索引发的情感词汇减少（p p 结论：bvFTD患者在“当时”和“现在”期间的情绪特征之间缺乏显著差异（以及两者的扁平化），这可能反映了他们情绪生成能力的障碍，这可能与重塑他们过去的经历以修改和调整其意义的困难有关。bvFTD中受阻的情绪调节也可能与回避策略和对过去的被动态度有关。

期刊介绍： Cognitive Neuropsychiatry (CNP) publishes high quality empirical and theoretical papers in the multi-disciplinary field of cognitive neuropsychiatry. Specifically the journal promotes the study of cognitive processes underlying psychological and behavioural abnormalities, including psychotic symptoms, with and without organic brain disease. Since 1996, CNP has published original papers, short reports, case studies and theoretical and empirical reviews in fields of clinical and cognitive neuropsychiatry, which have a bearing on the understanding of normal cognitive processes. Relevant research from cognitive neuroscience, cognitive neuropsychology and clinical populations will also be considered. There are no page charges and we are able to offer free color printing where color is necessary.
