"Identifying the Quintet of Personality Traits Linked to Dementia Risk"

A study from the University of California, Davis, involving 44,000 individuals aged 49 to 81, suggests that personality traits such as extroversion and conscientiousness may lower the risk of dementia, while neuroticism could increase it. This is linked to the concept of cognitive reserve, the brain's resilience to age-related damage, which can be bolstered by social activities, education, and lifestyle choices. The research highlights the importance of maintaining cognitive, social, and physical activities throughout life to build cognitive reserve and potentially reduce dementia risk.
