So, basically, this is a badly reported study because so many factors are mixed up together. People who are neurotic, and thus anxious or worrywarts and NOT necessarily also jealous or moody! In fact, many neurotic people are the exact opposite: they tend to go overboard to avoid being unfair to others.
Also notice that the main factor seemed to be a certain type of what this study is calling "neuroticism", i.e. moodiness and jealousy which they mix up with anxiety, who are UNDER STRESS, seem to be more inclined to develop Alzheimer's.
Anxiety, jealousy and moodiness in middle age are associated with doubling the risk of developing Alzheimer’s, a new study finds.
The study followed 800 women for 38 years and looked at the effects of their neuroticism on the chance of developing dementia.
Neuroticism is a personality trait that includes moodiness, worrying and anxiety.
In general, people who are neurotic are more likely to be anxious, depressed, jealous or envious.
Along with the personality test, the women were also asked if they’d recently been through a stressful period in their lives that lasted one month or more.
This could have been due to work, family, or other circumstance, and it might have caused irritability, lack of sleep, anxiety or fear.
The women were also given tests of their memory, since problems with this are one of the main signs of dementia.
The results showed that more neurotic women who were under high levels of stress were more likely to develop Alzheimer’s disease.
Out of the original 800, 63 women were high on neuroticism, and of these 25%, or 16 people developed Alzheimer’s
In comparison, 64 women were low on neuroticism and only 13%, or 8 of these people, developed Alzheimer’s.
