音乐诱发的自传式记忆（MEAMs）发生在阿尔茨海默氏痴呆症（AD）患者身上，但对其他类型痴呆症（如行为变异额颞叶痴呆（Bv-FTD））患者的这种记忆的研究有限。此外，还没有研究这些记忆随时间的完整性，也很少与其他记忆线索（如照片）进行比较。我们的目的是解决目前这方面的知识空白，并在健康老年人和阿尔茨海默病和Bv-FTD患者两种情况下（间隔6个月）描述MEAMs和光诱发自传体记忆（PEAMs）的特征。22名参与者（7名AD患者，6名Bv-FTD患者，9名健康老年人）在两次接触1930-2010年间每个十年的两首著名歌曲和两张著名事件照片后报告了记忆。所有AD患者和所有健康老年对照者在两次均报告至少一次MEAM或PEAM。相比之下，两名患有Bv-FTD的人在任何时候都没有记忆。健康老年人和AD组对歌曲和照片的记忆百分比保持稳定，而Bv-FTD患者对歌曲的记忆百分比随着时间的推移而增加。歌曲比照片更能唤起积极的记忆。触发记忆的特定音乐和照片刺激，以及被唤起的记忆主题，在所有组中都保持了6个月的稳定。我们的研究结果表明，音乐和照片是AD和Bv-FTD患者有效的记忆线索。未来对不同痴呆类型的人进行长期的大规模研究，将有助于深入了解随着痴呆的发展，音乐和照片诱发的自传体记忆的完整性。
Music evoked autobiographical memories (MEAMs) occur in people with Alzheimer’s dementia (AD), but there is limited study of such memories in people with other dementia types such as behavioral variant frontotemporal dementia (Bv-FTD). Furthermore, there has been no study of the integrity of such memories over time, and scarce comparison with other memory cues such as photos. Our aim was to address this current gap in our knowledge and to characterize MEAMs and photo-evoked autobiographical memories (PEAMs) in healthy elderly people and people with AD and Bv-FTD on two occasions, 6 months apart. Twenty-two participants (7 with AD, 6 with Bv-FTD, and 9 healthy elderly people) reported memories following exposure to two famous songs and two famous event photographs from each decade from 1930–2010 on two occasions. All people with AD and all healthy elderly controls reported at least one MEAM or PEAM at both times. In contrast, two people with Bv-FTD reported no memories at either time. The percentage of memories over time for songs and photos remained stable for the Healthy Elderly and AD groups, whilst the percentage of memories to songs increased over time for people with Bv-FTD. Songs elicited more positive memories than photos. The specific music and photo stimuli that triggered memories, and the topic of the memories that were evoked, remained stable over a 6-month period across all groups. Our results suggest that music and photos are efficient memory cues in people with AD and Bv-FTD. Future large-scale studies of people with different dementia types over a longer time period will provide insights into the integrity of music- and photo-evoked autobiographical memories as dementia progresses.
