Mental Activity and Healthy Aging: What the Research Suggests
What the cognitive reserve idea says about staying mentally active, and what research can and cannot show.
Key Research Takeaways
- Cognitive reserve is the idea that some people cope better with age-related brain changes because of their experiences and habits.
- Long-term studies, including the Nun Study, have linked mental activity with later cognitive health. Those links do not prove that puzzles cause better health.
- Physical activity, sleep and social contact are also widely linked with brain health.
The cognitive reserve idea
Neuropsychologist Yaakov Stern at Columbia University developed the cognitive reserve hypothesis to explain why people with similar brain changes can have different levels of thinking ability. Reserve may come from education, work and leisure activities that keep the mind engaged.
What the studies show
Research such as the Nun Study and the Rush Memory and Aging Project followed people for many years. Those studies found that mental activity is linked with better later-life cognition. The findings are observational, so engaged people may also differ in other ways.
A balanced approach
Puzzles are one part of a wider routine. Regular physical activity, enough sleep and time with other people are also associated with better brain health. Smotix is a fun way to keep your mind active. It is not a treatment for any condition.
