Anxiety, Jealousy, & Moodiness May Increase Alzheimer’s Risk in Women.
A woman’s risk for Alzheimer’s disease may be higher if she is anxious, jealous, or moody during middle-age. Over a 38-year period, researchers followed nearly 800 women who completed on-going personality tests regarding neuroticism, extraversion, and introversion. The study’s results show that women with the highest scores for neuroticism were twice as likely to develop Alzheimer’s as those with lower neuroticism scores. However, this association appeared to be greater among participants who had experienced long periods of stress. They also found that women who scored high on both neuroticism and introversion were at the highest risk for developing Alzheimer’s. Researcher Dr. Lena Johannsson writes, “Personality may influence the individual’s risk for dementia through its effect on behavior, lifestyle, or reactions to stress.”
