Background: A brain healthy lifestyle, consisting of good cardiometabolic health and being cognitively and socially active in midlife, is associated with a lower risk of cognitive decline years later. However, it is unclear whether lifestyle changes over time also affect the risk for mild cognitive impairment (MCI)/dementia, and rate of cognitive decline.
Objectives: To investigate if lifestyle changes over time are associated with incident MCI/dementia risk and rate of cognitive decline.

Objective: This study aimed to investigate the relationship between childhood adversity and cognitive impairment in older adults.
Methods: We analysed data from 1568 participants aged 72-79 (M = 75.1, SD = 1.

Article Synopsis
- Changes in the brain from Alzheimer's and other age-related diseases can cause problems with thinking and behavior, even before serious symptoms appear.
- The study looked at how a person's cognitive reserve (a mix of education and experiences) relates to mild behavioral issues.
- Results showed that people with a higher cognitive reserve had better brain test scores and fewer behavior problems, which suggests that keeping mentally active might help both thinking and behavior as we get older.
Article Synopsis
- A study involving 7,801 older adults examined the connection between fruit and vegetable consumption and the development of depression, finding that higher fruit intake was linked to a lower risk of depression.
- Over a follow-up period of 3 to 9 years, 21% of participants developed depression, with fruit intake showing a significant protective effect, while vegetable intake did not show a notable association.
- The authors noted limitations due to varied measurement methods and the relatively modest sample size, suggesting further research is needed on fruit and vegetable consumption in larger, more standardized studies among older adults in low- and middle-income countries.
Article Synopsis
- This study looked at how gender affects the relationship between skills from work (occupation), education, and the risk of mild cognitive impairment (MCI) in older people in Australia.
- It found that men are more affected by their job skills compared to women when it comes to the risk of MCI.
- For both men and women, engaging in more leisure activities and having better verbal intelligence helped reduce the risk of developing MCI, even more than education or job skills.
