There is bad news for all people with pessimistic nature! Seeing the glass half empty doesn't do you any good for your brain! A recent study, published in CNN, found that repeated negative thoughts were linked to Alzheimer's disease at a late stage in life.
Thinking negatively most of the time is a new risk factor that affects dementia. Behaviors of negative thoughts, such as all that has happened in the past or constant concern for the future, were studied in 350 people around the age of 55 for a period of 2 years.
About a third of participants underwent a brain scan to measure tau and beta amyloid deposits, two deposits that cause Alzheimer's, the most common type of dementia.
From the scanner?s result, it was concluded that people who spend more time thinking bad things have more pronounced memory problems compared to those who are optimistic in nature.
On the other hand, there was no increase in the deposits of the two proteins responsible for people suffering from anthocyanins and depression, leading researchers to suspect that repeated negative thoughts are one of the main reasons why anxiety and depression contribute to Alzheimer's disease.
This is the first study that deals with the link between thoughts and memory loss, but although other experiments are needed, many people do not know how much impact negative thoughts have on our brains.
People who always look at life from a positive perspective are more likely to avoid death due to cardiovascular problems.
