Personality and Alzheimer's Disease
Apart from biological factors such as amyloid plaques and tau tangles, new research suggests some personality traits may be risk factors for Alzheimer's disease. The factors have been proven to be causal but may be associated with Alzheimer's and related dementias.
Specifically, scientists found that neuroticism -- the personality trait that describes someone who gravitates toward unsettling emotions, such as anxiety and depression -- may increase the likelihood of developing amyloid plaques and tau tangles in the brain.
Conversely, the personality trait of conscientiousness -- being responsible, careful, goal- and detail-oriented -- may reduce the likelihood of developing them.
