APOE moderates the association between lifestyle activities and cognitive performance: evidence of genetic plasticity in aging.

ABSTRACT: The current study examined independent and interactive effects between Apolipoprotein E (APOE) genotype and two types of cognitively-stimulating lifestyle activities (CSLA)-integrated information processing (CSLA-II) and novel information processing (CSLA-NI)-on concurrent and longitudinal changes in cognition. Three-wave data across 6 years of follow-up from the Victoria Longitudinal Study (n=278; ages 55-94) and linear mixed model analyses were used to characterize the effects of APOE genotype and participation in CSLA-II and CSLA-NI in four cognitive domains. Significant CSLA effects on cognition were observed. More frequent participation in challenging activities (i.e., CSLA-NI) was associated with higher baseline scores on word recall, fact recall, vocabulary and verbal fluency. Conve
