“…Evidence of aging-related decline in various aspects of episodic memory is well established (e.g., see Dixon et al, 2004;Light, 1991;Zacks et al, 2000) for reviews. Most importantly, aging appears to compromise binding mechanisms, be it the association between content and context (e.g., Spencer and Raz, 1995), the concatenation of features into a compound memory item e.g., (Chalfonte and Johnson, 1996), or the generation of relations between different items (e.g., Li et al, 2005;Naveh-Benjamin, 2000).…”

“…However, the nature and time course of dynamic interactions among brain regions that contribute to encoding efficacy remain largely unknown. Methods with higher temporal resolution than current fMRI, such as electroencephalographic (EEG) recordings, are needed to shed light on the time course of encoding-relevant brain dynamics (e.g., Dixon et al, 2004;Klimesch, 1999;Kounios et al, 2001;Summerfield and Mangels, 2005).…”

“…The individual's ability to successfully remember past events is subject to profound lifespan changes (Baltes et al, 2006a;Dixon et al, 2004;Gathercole, 1998). Relatedly, various brain regions supporting encoding operations undergo substantial neurochemical (see Ba¨ckman and Farde, 2005;Benes et al, 2000 for reviews), anatomical Raz, 2005;Simons and Spiers, 2003 for reviews), and functional (see Cabeza, 2002;Johnson, 2001 for reviews) changes throughout life.…”

In the course of their lives, individuals experience a myriad of events. Some of them leave stable traces, and others fade away quickly. Recent advances in functional imaging methods allow researchers to contrast neuronal patterns of remembered against not remembered events at initial encoding. Research on young adults using functional magnetic resonance imaging (fMRI), intracranial, and standard electroencephalographic (EEG) recordings has identified differences between remembered and not remembered items in patterns of medio-temporal and prefrontal brain activity. However, little is known about the ways in which such neuronal patterns of successful encoding evolve across the lifespan as a function of maturation, senescence, and the accumulation of experience. Here, we first review empirical evidence on neuronal correlates of successful memory from middle childhood to old age. Based on the observation that associative and strategic components of episodic memory seem to follow different age gradients, we propose a conceptual framework for predicting age changes in neuronal patterns of successful encoding. r

“…A number of other studies, however, have failed to find significant gender differences in rates of cognitive aging (e.g., Aartsen, Martin, & Zimprich, 2004;Barnes et al, 2003;De Frias, Nilsson, & Herlitz, 2006;De Luca et al, 2003;Dixon et al, 2004;Herlitz, Nilsson, & Bäckman, 1997;Larrabee, Trahan, Curtiss, & Levin, 1988; 6 out of 8 tasks in Meinz & Salthouse, 1998;Rabbitt et al, 2003;Schaie, 1996;Singer, Verhaeghen, Ghisletta, Lindenberger, & Baltes, 2003). There have also been occasional reports of greater age-related cognitive decline in females than in males (Brayne, Gill, Paykel, Huppert, & O'Connor, 1995, in the over-75s; 2 out of 8 tasks in Meinz & Salthouse, 1998).…”

Gender and Sexual Orientation Differences in Cognition Across Adulthood: Age Is Kinder to Women than to Men Regardless of Sexual Orientation

Despite some evidence of greater age-related deterioration of the brain in males than in females, gender differences in rates of cognitive aging have proved inconsistent. The present study employed web-based methodology to collect data from people aged 20-65 years (109,612 men; 88,509 women). As expected, men outperformed women on tests of mental rotation and line angle judgment, whereas women outperformed men on tests of category fluency and object location memory. Performance on all tests declined with age but significantly more so for men than for women. Heterosexuals of each gender generally outperformed bisexuals and homosexuals on tests where that gender was superior; however, there were no clear interactions between age and sexual orientation for either gender. At least for these particular tests from young adulthood to retirement, age is kinder to women than to men, but treats heterosexuals, bisexuals, and homosexuals just the same.

“…Alterations in cognition appear to occur primarily in secondary memory systems, such as memory performance (e.g. delayed recall of a story presented once) (Dixon et al, 2004), processing, working memory (Corona et al, 2013), and executive function (Siedlecki et al, 2005). Increased fruits and vegetables intake has been associated with improved cognitive function (Sofi et al, 2010;Tangney et al, 2011;Lamport et al, 2016), and may be in large part attributable to intake of polyphenols (BarbergerGateau et al, 2007).…”

-Accumulating evidence suggests that diet and lifestyle can play an important role in delaying the onset or halting the progression of age-related health disorders and to improve cognitive function. A growing number of dietary intervention studies in humans and animals and in particular those using polyphenol-rich diets have been proposed to exert a multiplicity of neuroprotective actions within the brain, including a potential to protect neurons against injury induced by neurotoxins, an ability to suppress neuroinflammation and a potential to promote memory, learning, and cognitive functions. These effects appear to be underpinned by two common processes. First, they are capable of interactions with critical protein and lipid kinase signalling cascades in the brain, leading to an inhibition of apoptosis triggered by neurotoxic species and to a promotion of neuronal survival and synaptic plasticity. Second, they induce beneficial effects on the vascular system, leading to changes in cerebrovascular blood flow capable of causing enhance vascularisation and neurogenesis, two events important in the maintenance of cognitive performances. Together, these processes act to maintain brain homeostasis and play important roles in neuronal stress adaptation and thus polyphenols might have the potential to prevent the progression of neurodegenerative pathologies.
