Personality Traits, Do They Predict Cognitive Decline?

According to new research, extraverts and disciplined people are less likely to experience cognitive decline later in life, whereas neurotic people are more likely to experience cognitive dysfunction.

The researchers analysed data from nearly 2000 participants in the Rush Memory and Aging Project (MAP), a longitudinal study of older adults living in the greater Chicago metropolitan region and northeastern Illinois that began in 1997 and is still ongoing today. Participants were given a personality assessment as well as annual cognitive ability assessments.
