Older people who have higher levels of neuroticism are more likely to have worse cognitive function than those with other personality traits. Researchers say personality traits may be related to how well people can maintain their cognitive function, despite developing neuropathology associated with aging and dementia.
Certain personality traits could increase the risk of developing mild cognitive impairment, a new study reports. Openness was associated with a 6% reduced risk of developing a pre-dementia condition, while those who scored higher for neuroticism had a 6% increased risk of MCI.
According to researchers, having high levels of neuroticism may put people at higher risk of mood disorders. However, if the person is also extroverted or conscientious, the combined personality traits may act as a buffer against depression and anxiety.
Researchers have created a model of what they consider a 'healthy personality type', using contemporary trait perspective.
A new, comprehensive data analysis study challenges existing paradigms in psychology relating to personality types. Researchers report there appear to be four major clusters of personality types.
Higher polygenetic risk scores for schizophrenia, depression, neuroticism, and alcohol use disorder are indicators for higher risk of nicotine dependence.
Study reports a slightly elevated genetic risk of depression, schizophrenia, and neuroticism among adoptees. However, no association was found between the interaction of genetics and adoption on mental health. While adopted children had a slightly elevated risk for mental health disorders, the adoption process did not appear to increase the impact of the genetic risk.
People who are historically more reliant on the coal industry tend to have more negative personality traits, University of Cambridge researchers report. The researchers believe this could be a lasting effect of the Industrial Revolution.
People with high levels of neuroticism can be more avoidant in daily life as a coping mechanism, and this can commonly manifest into an addiction to the internet and social media.
