Stability, growth, and decline in adult life span development of declarative memory: cross-sectional and longitudinal data from a population-based study.
The results show that age trajectories for episodic and semantic memory differ and underscore the need to control for cohort and retest effects in cross-sectional and longitudinal studies, respectively.
Gender differences in episodic memory
The results demonstrated that women consistently performed at a higher level than did men on the episodic memory tasks, although there were no differences between men and women on the tasks assessing semantic memory, primary memory, or priming.
Structure-function correlates of cognitive decline in aging.
It is demonstrated that cognitive decline is associated with differences in the structure as well as function of the aging brain, and suggested that increased activation is either caused by structural disruption or is a compensatory response to such disruption.
The betula prospective cohort study: Memory, health, and aging
An overview of a prospective cohort study involving a total of 3,000 subjects whose ages were 35, 40, 45, 50, 55, 60, 65, 70, 75, and 80 years when first tested to determine early preclinical signs of dementia and assess premorbid memory functions.
Circadian Clock-Related Polymorphisms in Seasonal Affective Disorder and their Relevance to Diurnal Preference
Diurnal preference was associated with both SAD and seasonality, supporting the hypothesis of a link between circadian rhythms and seasonal depression and involvement of circadian clock-related polymorphisms both in susceptibility to S AD and diurnal preference.
Genetic contributions to variation in general cognitive function: a meta-analysis of genome-wide association studies in the CHARGE consortium (N=53 949)
In hypothesis-driven tests, there was significant association between general cognitive function and four genes previously associated with Alzheimer’s disease: TOMM40, APOE, ABCG1 and MEF2C.
Betula: A Prospective Cohort Study on Memory, Health and Aging
This article describes the Betula Study with respect to objectives, design, participants, and assessment instruments for health and cognition. Three waves of data collection have been completed in…
Activation of medial temporal structures during episodic memory retrieval
Results suggest that medial temporal activity is related to retrieval success rather than retrieval attempt, possibly by reflecting reactivation of stored patterns.

It can be concluded that episodic memory is unique in showing an age deficit, and is the only memory system showing gender differences in performance throughout the adult life span with a significantly higher performance for women.

The results support the reactivation hypothesis by showing that verbal-explicit memory of actions involves areas that are engaged during overt and covert motor activity.
