The trait may encourage people to keep their mind active, which is a protective factor against dementia.
People who are open to experience have a lower risk of developing dementia.
This personality trait, one of the five major aspects of personality, is linked to being more imaginative, sensitive to feelings, intellectually curious and seeking variety.
Openness may encourage people to keep their mind active, which a protective factor against dementia.
People who are more open also tend to have higher levels of education, which also reduces dementia risk.
The second personality trait linked to dementia in the study was neuroticism.
However, not all traits are protective: being neurotic increased the risk of developing dementia by 6 percent, the researchers found.
The major personality trait of neuroticism involves a tendency towards worry and moodiness.
People who are neurotic are more likely to experience negative emotions like depression, anxiety, guilt and envy.
Other studies have found that being neurotic may double the risk of developing dementia later in life.
Neurotic people are particularly sensitive to chronic stress.
Personality, though, is not destiny, when it comes to dementia — good brain health is about nature and nurture.
Many factors reduce dementia risk, such as a healthy lifestyle, which includes eating properly and getting enough exercise.
Indeed, making four out of five critical lifestyle changes can reduce the risk of Alzheimer’s by 60 percent.
Keeping the mind active is thought to reduce dementia risk.
Learning new activities, travelling and deepening social relationships may all be beneficial.
The present study included 524 people who were given tests of personality and symptoms of pre-dementia.
Ms Emmeline Ayers, the study’s first author, explained:
“While more studies are needed, our results provide evidence that personality traits play an independent role in the risk for or protection against specific pre-dementia syndromes.
From a clinical perspective, these findings emphasize the importance of accounting for aspects of personality when assessing for dementia risk.”
