Abstract:
Abstract. The cognitive reserve hypothesis postulates that lifelong cognitive stimulation establishes a buffer that is instrumental in maintaining cognitive health. To examine this conceptual proposition in detail, we applied a novel, more general conceptual view that included recent models of vulnerability and examined whether the longitudinal association between hepatobiliary diseases and later decline in executive functioning across 6 years varied by cognitive reserve. For this purpose, we investigated longitudinal data from 897 older individuals ( M = 74.33 years) tested using the Trail Making Test (TMT) in two waves 6 years apart. Individuals reported information on key commonly used indicators of lifelong cognitive reserve build-up (i.e., education, work, and participation in leisure activity) and hepatobiliary diseases. The results revealed a significant interaction of hepatobiliary diseases with participation in leisure activity on latent change in executive functioning. Specifically, only in individuals with little (but not greater) participation in leisure activity did hepatobiliary diseases significantly predict a steeper decline in executive functioning over 6 years (i.e., increases in TMT finishing time). In conclusion, the unfavorable aftereffects of hepatobiliary diseases on a later decline in executive functioning seem to be mitigated in individuals who have built up greater cognitive reserve via participation in leisure activity during their life.
