Use it or lose it: Engaged lifestyle as a buffer of cognitive decline in aging?

Article Abstract:

The hypothesis that maintaining intellectual engagement through participation in everyday activities acts as a buffer against cognitive decline in later life was examined using data from the Victoria Longitudinal Study. A link between changes in intellectually related activities and changes in cognitive functioning was found, consistent with the hypothesis. However an alternative model agrees with the hypothesis that high ability individuals lead intellectually active lives until cognitive decline limits their activities in old age.
