Having a positive approach to life may help protect against dementia, reducing the risk of developing it by at least 15%, according to a new study.
There is growing evidence that an optimistic attitude helps people stay physically and mentally active well into old age. This study is among the first to directly examine the link between optimism and dementia risk in older adults with normal cognitive function.
Researchers followed more than 9,000 adults in the U.S. for about 14 years, with an average age of 73. Optimism was measured through a standard test that assesses expectations for the future, where participants expressed their level of agreement with statements such as: “In uncertain situations, I usually expect the best” or “I am optimistic about my future.”
In this context, optimism does not simply mean positive thinking, but the way individuals deal with life's challenges. In contrast, pessimism is associated with negative expectations and a focus on problems.
The results showed that for every six-point increase in optimism level, the risk of dementia decreased by about 15%.
To ensure the accuracy of the link, the researchers continuously monitored the participants' mental health and excluded cases where dementia appeared in the early stages of the study. Even after these analyses, the link between optimism and lower risk remained strong.
The exact reasons why optimism has this protective effect aren't entirely clear, but experts suggest several possible mechanisms. A positive attitude is linked to lower stress levels, a healthier immune system, and stronger social networks. Optimistic people are also more likely to be physically active.
Experts emphasize that research into dementia prevention is essential, as a large proportion of cases are related to factors that can be changed, such as lifestyle or social isolation.
Currently, around 900,000 people are living with dementia in the UK, and this number is expected to rise significantly in the coming decades. However, it is believed that many cases could be prevented through simple lifestyle changes – including a more positive approach to life.
In conclusion, optimism is not just a character trait, but may be an important factor for brain health and healthy aging. /GazetaExpress/
