Researchers found that the more people use their brains at work, the better they seem to be protected against thinking and memory problems that come with older age. In a study of more than 7,000 Norwegians in 305 occupations, those in the least mentally demanding jobs had a 66% greater risk of mild cognitive impairment, and a 31% greater risk of dementia after the age of 70.
The study highlighted the importance of work in maintaining cognitive function, emphasizing the significance of engaging in mentally stimulating tasks throughout one's career. Engaging in challenging cognitive tasks can potentially reduce the risk of cognitive decline as individuals age.
The research also revealed that individuals who started work in less mentally stimulating jobs were more likely to remain in those roles throughout their careers, suggesting the importance of early exposure to cognitive challenges in the workforce.
