Introduction: Little is known about mind wandering in Alzheimer's disease (AD). In this study, we evaluated the subjective experience of mind wandering in AD.Methods: We invited AD patients and control participants to rate the occurrence, intentionality, emotionality, visual imagery, specificity, self-relatedness and temporal orientation of mind wandering.Results: Analysis showed that AD patients rated their mind wandering as more frequent, negative, and more oriented toward the past, but less vivid and specific than that of control participants. No significant differences were observed between AD patients and control participants regarding the intentionality or self-relatedness of mind wandering.Conclusions: These findings demonstrate the negative content in AD. Regarding the reduction of visual imagery and specificity during mind wandering, this reduction may mirror a diminished subjective experience of mind wandering in AD. Regarding temporality, our results may reflect a tendency of AD patients to reminisce over past experiences. Finally, mind wandering in AD seems to trigger significant self-related content.

心智在阿尔茨海默氏病中游荡的主观经验。

简介：人们对阿尔茨海默氏病（AD）中的心灵游荡知之甚少。在这项研究中，我们评估了AD中心理游荡的主观经验。方法：我们邀请AD患者和对照组参与者对心理游荡的发生，意图，情感，视觉形象，特异性，自相关性和时间取向进行评估。分析表明，AD患者对他们的思想游荡的评价是更频繁，消极和更倾向于过去，但与对照组相比，却不那么生动和具体。在AD患者和对照参与者之间，在游荡的意向性或自我相关性方面没有观察到显着差异。结论：这些发现表明AD中的负含量。关于在游荡过程中视觉形象和特异性的降低，这种减少可能反映了AD中心理徘徊的主观体验减少。关于暂时性，我们的结果可能反映了AD患者回想过去的经历的趋势。最后，在AD中徘徊的思维似乎会触发大量与自我相关的内容。
