多项研究表明，阿尔茨海默病（AD）的自传体记忆和现象学重现存在妥协。我们研究了自传体记忆的各种现象学特征，以确定它们在AD中的相对脆弱性。为此，研究人员要求患有早期AD的参与者和认知正常的老年人对照者检索一个自传体事件，并以五分制对元认知判断（即再现、回到过去、记忆和真实性）、组成过程（即视觉图像、听觉图像、语言和情感）、叙事属性（即排练和重要性）和时空特异性（即空间细节和时间细节）进行评分。与对照组相比，AD参与者表现出较低的一般自传体记忆，以及较差的再现、时间旅行、记忆、真实性、视觉意象、听觉意象、语言、排练和空间细节，其中视觉意象的下降尤为明显。然而，AD参与者在情感和重要性方面表现出较高的评分。早期AD似乎损害了许多现象学特征，特别是视觉意象，但似乎也保留了一些其他特征。
Multiple studies have shown compromise of autobiographical memory and phenomenological reliving in Alzheimer's disease (AD). We investigated various phenomenological features of autobiographical memory to determine their relative vulnerability in AD. To this aim, participants with early AD and cognitively normal older adult controls were asked to retrieve an autobiographical event and rate on a five-point scale metacognitive judgments (i.e., reliving, back in time, remembering, and realness), component processes (i.e., visual imagery, auditory imagery, language, and emotion), narrative properties (i.e., rehearsal and importance), and spatiotemporal specificity (i.e., spatial details and temporal details). AD participants showed lower general autobiographical recall than controls, and poorer reliving, travel in time, remembering, realness, visual imagery, auditory imagery, language, rehearsal, and spatial detail a decrease that was especially pronounced for visual imagery. Yet, AD participants showed high rating for emotion and importance. Early AD seems to compromise many phenomenological features, especially visual imagery, but also seems to preserve some other features.
