A new study says that these two personality traits may increase the risk of Alzheimer’s disease
Alzheimer’s disease is a devastating and fatal condition for which there is no known cure. Not only Alzheimer’s disease The sixth leading cause of death in the United States and the fifth leading cause of death among the U.S. population aged 65 or older, but the prevalence of Alzheimer’s disease also increased by 55% in the United States between 1999 and 2014 alone, CDC . Reports.
While the means by which Alzheimer’s disease can be effectively treated are not yet broken, a new study suggests that there may be a way to predict — and possibly protect yourself from — this type of progressive dementia.
To conduct their investigation, a group led by researchers from the Departments of Geriatrics and Behavioral Sciences at Florida State University College of Medicine and the National Institutes of Health reviewed the results of participants in the Baltimore Longitudinal Study of Aging who subsequently took a personality-modified inventory of NEOs. She underwent positron emission tomography, amyloid and tau scans, and the results of 12 studies examining Alzheimer’s disease and personality.
Study researchers found that individuals who did not notice perceptual A disability was more likely to develop Alzheimer’s disease if it showed more clear signs of neuroticism. Individuals from this group who showed lower levels of conscientiousness were more likely to develop Alzheimer’s disease. These findings were based on the number of amyloid and tau deposits, the types of brain biomarkers associated with the development of Alzheimer’s disease, found in the brains of the subjects.
While this may sound like bad news for individuals with these personality traits, the study authors suggest that these biomarkers may be linked to modifiable factors, such as individuals’ emotional states and lifestyle choices.
He explained that “this protection from neurological diseases may stem from a difference in people’s emotions and behaviors for life.” Antonio Terracciano, Ph.D., professor of geriatrics at Florida State University College of Medicine, in the current situation.
“For example, previous research has shown that reduced neuroticism helps with this stress management It reduces the risk of common mental health disorders. Likewise, a higher conscience is consistently associated with healthy lifestyles, such as physical activity. Over time, more adaptive personality traits can support better metabolic and immune functions, and eventually prevent or delay the neurodegenerative process. “
Supporting this idea, research published in Biological Reviews In 2021, it was found that chronic stress and elevated levels of cortisol, a stress hormone, are associated with the development of Alzheimer’s disease. Studies have also found that both exercise And Increase antioxidants Intake is associated with lower rates of Alzheimer’s disease, indicating that your personality alone will not take an Alzheimer’s diagnosis for granted.
