1. Introduction
Decline in both associative memory and the structural and functional integrity of the hippocampus is common in healthy aging [1–4]. There are however limitations to our knowledge about the effects of aging on the hippocampus and associative memory; such as older groups primarily being compared to young groups and rarely middle-aged, as well as age-related effects being assessed independently of sex, implying the assumption that age affects the hippocampus and associative memory equally in men and women − two groups that separately have been reported to differ in both associative memory performance and rates of age-related hippocampal atrophy [5,6]. Here, we assess the effects of age on associative memory performance and the volume and function of the hippocampus in middle-aged and older adults, specifically taking sex into account. The hippocampus is thought to primarily contribute to memory processes requiring the formation and retrieval of associations between items [7–9], as reported in both patient studies [10–13] and neuroimaging studies on healthy young adults [14–17]. Hippocampal involvement is often evident in successful encoding and retrieval, as studied with event-related paradigms [18,19], and in general, associative memory commonly involves the anterior part of the hippocampus, with activation lateralized to the left when the material tested is verbal and otherwise most often to the right [19,20]. The volume of the anterior hippocampus is also predictive of associative memory performance in young adults [21]. As the hippocampus, and primarily its anterior regions, has been shown to be especially sensitive to age-related atrophy [2,3,22–26]; but see Ref. [27], it is plausible that associative memory is particularly susceptible to the effects of aging. This has in fact been reported by several studies [28,29]; see Ref. [30] for a metaanalysis], and termed the Associative Deficit Hypothesis (ADH). It predicts larger age-related deficits in associative memory as compared to single-item memory [1], and although it is most often compared between younger and older groups, it has also been demonstrated across a life-spansample includingmiddle-aged participants [6].
