摘要: Abstract The apolipoprotein E ( APOE ) ɛ4 allele and high levels of beta-amyloid (Aβ) are associated with episodic memory decline risk for Alzheimer's disease. However, there is debate about independent or interactive effects on Aβ-related in healthy older adults. Healthy adults Aβ burden (n = 84) enrolled Australian Imaging, Biomarkers, Lifestyle Study were included this study. Cognition was measured using the computerized Cogstate Brief Battery at baseline, 18-, 36-, 54-month follow-ups. Mini Mental State Examination Clinical Dementia Rating scales also administered baseline each follow-up timepoint. Relative to Aβ+ noncarriers 36), carriers 48) showed significantly faster tasks, which by convention, moderate magnitude d = 0.40–0.47). positivity coupled moderately increased over a assessment period, suggesting that, preclinical stages disease, manifestation exacerbated presence ɛ4.
