脑老化和阿尔茨海默病(AD)之间的关系存在争议。一种观点认为,当大脑老化超过一个阈值时,AD就会出现。另一种观点认为AD不是大脑老化的结果。这篇评论讨论了这个难题的角度不同的调查线,试图解决它,以及从的角度来看,在AD和脑老化的细胞器,似乎发挥了作用。具体问题包括AD和脑老化是否应该在概念上集中或分裂,AD和脑老化可能共享共同分子机制的程度,β淀粉样蛋白是否应该主要被认为是AD的标志物或简单的脑老化,以及AD本身的定义。
The relationship between brain aging and Alzheimer’s disease (AD) is contentious. One view holds AD results when brain aging surpasses a threshold. The other view postulates AD is not a consequence of brain aging. This review discusses this conundrum from the perspective of different investigative lines that have tried to address it, as well as from the perspective of the mitochondrion, an organelle that appears to play a role in both AD and brain aging. Specific issues addressed include the question of whether AD and brain aging should be conceptually lumped or split, the extent to which AD and brain aging potentially share common molecular mechanisms, whether beta amyloid should be primarily considered a marker of AD or simply brain aging, and the definition of AD itself.
