Conscientious people may not develop Alzheimer's

clipped from blogs.usatoday.com A new study suggests people who have a "purposeful personality" are less likely to develop Alzheimer's disease. Reuters says those who "lead a good clean life" are less prone to developing dementia in later life, according to the Rush University Medical Center study. "When the researchers took into account a combination of risk factors, including smoking, inactivity and limited social connections, they still found that the dutiful people had a 54 percent lower risk of Alzheimer's compared to people with the lowest scores for conscientiousness," the Associated Press reports.
