在年轻人中，最近学到的情景记忆在慢波睡眠（SWS）期间被重新激活和巩固。有趣的是，SWS在整个生命周期中都会下降，但很少有研究调查睡眠依赖性记忆巩固是否会发生在老年人身上。在目前的研究中，年轻的成年人和健康的老年人在早上或晚上编码单词对，然后在睡眠或不睡眠的间隔后返回。睡眠阶段评分采用家庭睡眠阶段监测系统。在年轻成人组中，单词记忆与SWS的数量呈正相关。相比之下，老年人的记忆与SWS之间没有显著的正相关，但有显著的负相关。这些发现表明，通常在年轻人中观察到的情景记忆和SWS之间的联系可能在健康的老年人中被削弱或改变。
In younger adults, recently learned episodic memories are reactivated and consolidated during slow-wave sleep (SWS). Interestingly, SWS declines across the lifespan but little research has examined whether sleep-dependent memory consolidation occurs in older adults. In the present study, younger adults and healthy older adults encoded word pairs in the morning or evening and then returned following a sleep or no-sleep interval. Sleep stage scoring was obtained using a home sleep-stage monitoring system. In the younger adult group, there was a positive correlation between word retention and amount of SWS. In contrast, the older adults demonstrated no significant positive correlations, but one significant negative correlation, between memory and SWS. These findings suggest that the link between episodic memory and SWS that is typically observed in younger adults may be weakened or otherwise changed in the healthy elderly.
