Data containing demographic, biomarker and cognitive data in a subgroup of cognitively normal older adults who underwet PET neuroimaging for amyloid, and who had completed 18 month assessments of a brief computerized cognitive battery as part of the Australian Imaging, Biomarkers and Lifestyle (AIBL) Study.本数据集收录了某亚组认知正常老年人群的人口统计学数据、生物标志物数据与认知数据。该亚组人群曾接受针对淀粉样蛋白的正电子发射断层扫描（PET）神经成像检查，且作为澳大利亚影像、生物标志物与生活方式（AIBL）研究的一部分，完成了为期18个月的简易计算机化认知测验组合评估。
