Certain personality traits associated with cognitive functio
Personality traits reflect relatively enduring patterns of thinking and behaving, which may cumulatively affect engagement in healthy and unhealthy behaviors and thought patterns across the lifespan. The accumulation of lifelong experiences may then contribute to susceptibility of particular diseases or disorders, such as mild cognitive impairment, or contribute to individual differences in the ability to withstand age-related neurological changes. The researchers focused on the role three of the so-called "Big Five" personality traits (conscientiousness, neuroticism and extraversion) play in cognitive functioning later in life.

Researchers analyzed data from 1,954 participants in the Rush Memory and Aging Project, a longitudinal study of older adults. Participants without a formal diagnosis of dementia were recruited. Participants received a personality assessment and agreed to annual assessments of their cognitive abilities.

People who are organized, with high levels of self-discipline, may be less likely to develop mild cognitive impairment as they age, while people who are moody or emotionally unstable are more likely to experience cognitive decline late in life. There was no association between any of the personality traits and total life expectancy.
