Individuals with personality traits such as conscientiousness, extraversion, and positive affect are less likely to be diagnosed with dementia than those with neuroticism and negative affect, according to a new analysis by researchers at the University of California, Davis, and Northwestern University. The difference was not linked to physical damage to brain tissue found in dementia patients, but more likely to how certain personality traits help people navigate dementia-related impairments.
The work was recently published in Alzheimer’s & Dementia: The Journal of the Alzheimer’s Association.
Previous studies have tried to establish links between personality traits and dementia, but these were mostly small and represented only specific populations, said Emorie Beck, assistant professor of psychology at UC Davis and first author on the paper.
