Skeptics are more likely to develop dementia

(Persons looking at the world around a negative perspective are at increased risk of cognitive decline later.

For the first time, a study has shown that skeptics, who don't trust others, are three times more likely to develop dementia than those who trust others.

Scientists believe that those who achieve everything they want by being motivated by selfishness and lies are likely to increase the risk of cognitive decline in later life.

That means a thorough health check, especially Alzheimer's disease for the grumpy elderly. According to previous studies, skepticism is related to health problems such as heart disease, but this is the first time it has been shown to be linked to dementia.

'These results increase evidence of people's views on life and their personalities that can affect health, ' said researcher Dr. Anna-Maija Tolppanen from Eastern Finland University. .

'Understanding how personality traits (such as skepticism ) affect the risk of dementia helps us to have a better understanding of reducing the risk of dementia.'

Researchers surveyed nearly 1,500 people, an average of 71 years old, and asked them to fill out a questionnaire to assess skepticism. They were asked questions like, do you agree with the statement: 'I think most people lie to achieve success',' Don't trust who is the safest ',' Most people will use deceitful explanation to increase profit or advantage for yourself rather than to lose it. '

The researchers followed for eight years and during that time 46 people were diagnosed with dementia. At the same time, they found that those with high scores in the skeptic test were three times more likely to develop dementia.

Scientists have also adjusted other factors that may affect the risk of dementia such as high blood pressure, high cholesterol levels and smoking, the results remain the same. Of the 164 people with high levels of skepticism, 14 were insane compared to 9 out of 212 people with low levels of skepticism. However, charities also warned that symptoms of Alzheimer's disease and dementia can make people more skeptical about life.

"While this study attempts to create a link between higher levels of skepticism and the risk of dementia, there are too few people in the study who actually suffered Alzheimer. So it is difficult to draw any firm conclusions'.

'However, we also know that some people with dementia with symptoms of delusion, confusion and mood disorders can lead to suspicion and suspicion.'

'Giving deeper knowledge of the less-known symptoms of dementia including changes in personality and depression will help us better understand this problem and may improve things. treatment and care as well as giving them support '.

Researchers don't know what makes this connection. It may be due to an increase in stress hormones known to increase the risk of dementia. The author also said that this result shows the role of dementia affecting people's attitudes - a problem that doctors can consider.

However, this study does not find a link between skepticism and premature death. The study is published online in the journal Neurology, a medical journal of the American Neurological Institute (AAN).
