People with personality traits such as conscientiousness, extroversion, and positive affect were found to be less likely to be diagnosed with dementia than those with neuroticism and negative affect. [사진= 게티이미지뱅크]There are many factors that contribute to the onset of dementia. There are genetic factors and environmental factors. However, research has shown that certain personality traits such as conscientiousness, extroversion, and positive emotions can lower the risk of dementia diagnosis.

A study published in the Alzheimer’s Association journal, Alzheimer’s & Dementia, found that people with personality traits such as conscientiousness, extroversion, and positive affect were less likely to be diagnosed with dementia than those with neuroticism and negative affect.

Researchers from the University of California and Northwestern University analyzed data from eight published studies involving more than 44,000 people, 1,703 of whom had dementia. They compared five key personality traits (conscientiousness, extraversion, openness to experience, neuroticism and agreeableness) and subjective well-being (positive and negative affect, satisfaction with life) with clinical symptoms of dementia (cognitive test scores) and brain pathology at autopsy. ) was investigated.

The study found that scoring high on negative traits (neuroticism, negative affect) and low on positive traits (conscientiousness, extraversion, positive affect) increased the risk of being diagnosed with dementia. High scores on openness to experience, agreeableness, and life satisfaction appeared to have a protective effect.

“Rather than being related to the physical damage to brain tissue found in dementia patients, it is more likely to be related to the way certain personality traits help overcome dementia-related disabilities,” the researchers said. “In general, personality is influenced by behavior. It is thought to be related to the risk of dementia. “For example, people who score high on conscientiousness are more likely to eat well and take care of their health, which may lead to better health in the long term.”

Notably, no correlation was found between these personality traits and the actual neuropathology found in people’s brains after death. “This was the most surprising finding for us,” the researchers said. “The fact that personality predicts performance on cognitive tests, but not pathology, suggests that some personality traits may increase resilience to damage from diseases such as Alzheimer’s. “He said. People with high levels of some personality traits are able to cope with their disorders and find ways to work around them, whether they are aware of it or not.

Emory Beck, first author of the paper, said, “Changing personality traits through intervention early in life may be a way to reduce the risk of dementia in the long term.”
