Some Personality Traits Appear to Be Linked to Cognitive Impairment Later in Life

Having specific personality traits might be connected to our risk of developing cognitive problems later on in life, new research suggests – and that in turn might point to better ways of treating issues like dementia.

A total of 1,954 volunteers without a formal diagnosis of dementia took part in the study, filling out personality questionnaires that were cross-checked against their health records and any cognitive problems as they got older. Curiously enough, organized and self-disciplined people appeared less likely to develop mild cognitive impairment, whereas neurotic people were more prone to it.

As this was a correlational study, it’s not clear if there are fundamental aspects of biology underpinning the link, but the researchers have their suspicions.
