大脑淀粉样蛋白可以用正电子发射断层扫描来测量。关于淀粉样蛋白测量是否与认知(特别是记忆)测量相关,这取决于评估的队列和认知域,有各种不同的报告。在阿尔茨海默病(AD)患者和AD高危人群中,认知表现可能与经典AD病理(淀粉样斑块和神经纤维角)的水平和程度有关,但也受到神经退行性变、神经认知储备和血管健康的影响。我们讨论了最近的神经成像研究在AD认知缺陷方面的发现,并为未来的研究提供了建议。
Brain amyloid can be measured using positron emission tomography. There are mixed reports as to whether amyloid measures are correlated with measures of cognition (in particular memory) depending on the cohorts and cognitive domains assessed. In Alzheimer's disease (AD) patients and those at heightened risk for AD, cognitive performance may be related to the level and extent of classical AD pathology (amyloid plaques and neurofibrillary angles), but it is also influenced by neurodegeneration, neurocognitive reserve, and vascular health. We discuss what recent neuroimaging research has discovered about cognitive deficits in AD, and offer suggestions for future research.
