IT'S time to put on those rose-tinted glasses - optimism has now been scientifically proven to lower your risk of dementia.
A US study followed more than 9,000 cognitively healthy adults with an average age of 73 for around 14 years.
The adults took part in a Life Orientation Test every four years, with 10 questions about their expectations of the future.
"Together with previous studies, our findings provide support for the possibility that optimism causally contributes to cognitive health and may be considered an asset for brain health," wrote the researchers.
Participants also did repeated memory tests to spot any issues around probable dementia.
The researchers suggested that optimism may be able to protect individuals against dementia through its link to a healthier immune response, and noted it also contributes to having more psychosocial resources, such as stronger social networks, and is associated with having lower levels of stress.
