ANXIOUS, jealous, moody or distressed middle-aged women may be putting themselves at risk of developing Alzheimer's according to a 38-year long study.
The claim, in Neurology online, comes after scientists used personality and memory tests to track the health and welfare of 800 women, average age 46.
They found that 19 per cent of those women developed dementia in later life.
The tests also looked at neuroticism levels, which involves being easily distressed and can be linked to worrying, jealousy and moodiness, as well as whether they appeared to be shy and reserved or were outgoing characters.
Study author Lena Johannsson of the University of Gothenburg, Sweden, said: "Most Alzheimer's research has been devoted to factors such as education, heart and blood risk factors, head trauma, family history and genetics.
"Personality may influence the individual's risk for dementia through its effect on behaviour, lifestyle or reactions to stress."
Why are you making commenting on The Herald only available to subscribers?
It should have been a safe space for informed debate, somewhere for readers to discuss issues around the biggest stories of the day, but all too often the below the line comments on most websites have become bogged down by off-topic discussions and abuse.
heraldscotland.com is tackling this problem by allowing only subscribers to comment.
We are doing this to improve the experience for our loyal readers and we believe it will reduce the ability of trolls and troublemakers, who occasionally find their way onto our site, to abuse our journalists and readers. We also hope it will help the comments section fulfil its promise as a part of Scotland's conversation with itself.
We are lucky at The Herald. We are read by an informed, educated readership who can add their knowledge and insights to our stories.
That is invaluable.
We are making the subscriber-only change to support our valued readers, who tell us they don't want the site cluttered up with irrelevant comments, untruths and abuse.
In the past, the journalist’s job was to collect and distribute information to the audience. Technology means that readers can shape a discussion. We look forward to hearing from you on heraldscotland.com
