People who feel more cheerful and enthusiastic or have a positive outlook in psychological terms are less likely to undergo memory decline as they age, finds a new study.
The research, published by journal Psychological Science, adds to the growing body of work suggesting the power of positive thinking in healthy ageing.
To test the hypothesis, researchers analysed data of nearly 1,000 American adults during three time periods between 1995 to 2014.
Lead researcher and professor at Northwestern University said the findings showed that memory declines with age but 'individuals with higher levels of positive affect had a less steep memory decline over the course of almost a decade.'
