This longitudinal, prospective, observational study aims to examine the association between intellectual engagement and cognitive ability in later life, and determine whether the maintenance of intellectual engagement will offset age related cognitive decline.

Overall, findings suggest that high performing adults engage and those that engage more being protected from relative decline.
