摘要

嗅觉和陈述性记忆表现是相关的,因为这两种功能都是通过重叠的内侧颞叶和前额叶结构以及老年人的衰退来处理的。虽然嗅觉识别能力的下降可能与陈述性记忆的下降有关,但嗅觉检测阈值和陈述性记忆力之间的关系尚不清楚。在这项荟萃分析中,我们评估了(1)认知正常的老年人的嗅觉识别/检测阈值与言语陈述性记忆之间的关系,以及(2)年龄对这些关系的影响。我们根据以下标准纳入了PsychNet、PubMed和Academic Search Complete的文章:1)纳入认知正常的老年人;2) 情节记忆或语义记忆的评估;以及3)嗅觉识别或检测阈值的评估。17项研究和22个效应大小符合条件并纳入本荟萃分析。嗅觉识别与情节(小效应大小:r=.19;k=22)和语义记忆(小效应尺寸:r=.16;k=23)相关。类似地,嗅觉检测阈值与情节(中小效应大小:r=.25;k=5)和语义记忆(小效应大小:r=.17;k=7)有关。年龄被发现调节嗅觉检测阈值和记忆表现之间的关系。老年人的嗅觉识别和检测阈值表现都与陈述性记忆有关,年龄只调节嗅觉检测阈值和陈述性记忆力表现之间的关系。

Olfaction and declarative memory in aging: a meta-analysis.

Olfactory and declarative memory performances are associated, as both functions are processed by overlapping medial-temporal and prefrontal structures and decline in older adults. While a decline in olfactory identification may be related to a decline in declarative memory, the relationship between olfactory detection threshold and declarative memory remains unclear. In this meta-analysis, we assessed (i) the relationship between olfactory identification/detection threshold and verbal declarative memory in cognitively normal older adults, and (ii) the effect of age on these relationships. We included articles from PsychNet, PubMed, and Academic Search Complete according to the following criteria: (i) inclusion of cognitively normal older adults; (ii) assessment of episodic or semantic memory; and (iii) assessment of olfactory identification or detection threshold. Seventeen studies and 22 effect sizes were eligible and included in this meta-analysis. Olfactory identification was associated with episodic (small effect size: r = 0.19; k = 22) and semantic memory (small effect size: r = 0.16; k = 23). Similarly, the olfactory detection threshold was associated with both episodic (small to medium effect size: r = 0.25; k = 5) and semantic memory (small effect size: r = 0.17; k = 7). Age was found to moderate the relationship between olfactory detection threshold and memory performance. Both olfactory identification and detection threshold performances are associated with declarative memory in older adults, and age only moderates the relationship between olfactory detection threshold and declarative memory performances.
