Does problem-solving really protect against cognitive decline in old age?

Press/Media: Articles in 'The Conversation'


“Use it or lose it” is the received wisdom when it comes to cognitive ability. But is there any truth in this old saw? Our latest study suggests that it depends how much “it” you have to start with.

Previous observational studies that looked at the effect of doing mentally stimulating activities, such as puzzles, on cognitive ability have largely supported the “use it or lose it” hypothesis. However, these studies have often been based on snapshots in time – so-called cross-sectional studies. To find out if there really is a link between mental engagement over a lifetime and cognitive ability in old age, you need to track people’s habits and mental abilities over a lifetime.
