Summary: Physical activity is associated with better episodic memory function and may prevent potential decline in diabetic patients. No significant association was found between physical activity and executive function.

Summary: This study investigated the effects of normal cognitive aging on executive functions and verbal episodic memory in the old Greek Cypriots. It found that education level was predictive of verbal episodic memory and executive function performance.

Summary: This study examined the effects of repeated testing and aging on episodic memory and executive function in older adults. Results showed that retest effects were significant for memory but not for executive function. When practice effects were removed, aging effects were evident for both memory and executive function.

Summary: This study aims to assess the differential prognostic value of cognitive performance in older men versus women. Through longitudinal analysis, it was found that in the cognitively unimpaired population, episodic memory and verbal fluency were more related to the risk of future AD in women, while naming, attention, and executive function were more related to the risk of future AD in men in the mild cognitive impairment population.

Summary: With the aging of the population, it is important to keep individuals cognitively healthy. Vascular aging has a negative impact on cognitive skills, increasing the risk of dementia. This study focuses on two groups - adults with vascular risk factors and those with both vascular risk factors and mild cognitive impairment. The findings show that global cognitive status and short-term memory decline in individuals with vascular risk factors, while Theory of Mind abilities can better capture the impairment in those with both risk factors and mild cognitive impairment.

Summary: Depressive symptoms were predictive of lower episodic memory and executive function. Nurses should pay attention to depressive symptoms in older adults with SCD, as managing depressive symptoms may help prevent cognitive decline more typical of early Alzheimer's dementia.

Summary: Limited research has been done on the relationship between social stress and cognitive decline in aging individuals. The study found that lower subjective social status and discrimination stress had adverse effects on episodic memory, with women reporting lower social status and more discrimination stress than men. Marital risk had negative effects on episodic memory in men, while daily discrimination had adverse effects on executive functioning in all individuals. Strategies for public health should focus on reducing social stress, particularly subjective social status and discrimination stress.

Summary: This study found that racial disparities in executive function and episodic memory in middle-aged and older adults can be partly explained by cumulative stress exposures across the life course.

Summary: This study found that cumulative stress exposure is associated with poorer cognitive function and faster cognitive decline. Both high stress in childhood and adulthood were linked to lower executive function and episodic memory. However, there was little evidence to suggest that the rate of decline in cognitive function differed across levels of stress exposure.

Summary: The relationship between APOE status and CSF p-tau may be mediated by the interaction between sex and cerebrospinal fluid Al3. These findings suggest that tau accumulation may be independent of Al3 in females, but not in males.

Summary: Laboratory studies have shown that stress impairs memory retrieval of individual parts of a memory, particularly linked to the stress hormone cortisol. This study aimed to investigate the effects of pharmacologically elevated cortisol levels on item and associative memory retrieval, as well as any potential sex differences. The results demonstrated that cortisol levels distinctly affect associative memory in female and male participants, but have no effect on item memory, suggesting a complex interaction for stress effects on memory.

Summary: Considerable evidence supports sex differences in episodic memory. This study found that the hormones estradiol and oxytocin can modulate these sex differences, with separate treatments significantly reducing the differences and combined treatment having no effect. The results suggest the importance of these hormones in regulating sex differences in episodic memory, and possible antagonistic interactions between estradiol and oxytocin.

Summary: Black students attending historically Black colleges and universities (HBCUs) report more discrimination and worse mental health outcomes compared to those attending predominantly White institutions (PWIs), potentially offsetting the established benefits of college for lowering dementia incidence.

Summary: The study in a rural South African community examined the association between APOE genetic variation and cognitive function. Results suggest marginally significant associations between APOE genotype and executive function and visuospatial ability in African populations, highlighting the need for larger studies to confirm these associations.
