Popis: | INTRODUCTION: Questions remain about whether APOE-ε4 effects on cognitive decline are similar in men and women and how APOE-ε4 and age interact to influence decline in different cognitive domains. METHODS: In sex stratified analyses, age-dependent associations between APOE-ε4 status and longitudinal cognitive trajectories were examined in cognitively normal older adults (631 men, 561 women, baseline age range: 50–93, 6733 assessments). Where age-dependent relationships were found, age of divergence in trajectories for APOE genotypes was estimated. RESULTS: In men, APOE-ε4 had significant age-dependent effects on longitudinal decline in memory and executive function detectible from baseline age of 64 and 68, respectively. In women, APOE-ε4 had a significant age-dependent effect on longitudinal decline in attention detectible at baseline age of 66. No significant APOE-ε4 effects were found for language, visual-spatial ability or processing speed. DISCUSSION: Results highlight the importance of considering sex and age when assessing APOE-ε4 associated vulnerability to cognitive decline. |
