Coffee is a drink that many of us enjoy and, as most of us know, the main ingredient in coffee is caffeine, a stimulant that excites the nervous system and is responsible for that pick-me-up feeling. Scientists have known for a long time that caffeine can provide us with a short boost to our attentional processing, as well as our memory. So it seems logical to think that something that helps our cognition might actually be beneficial for diseases that impair our cognition.

咖啡是我们许多人喜欢的一种饮料。正如我们大多数人所知道的,咖啡的主要成分是咖啡因,它是一种刺激神经系统并负责挑剔感觉的兴奋剂。很长一段时间科学家已经知道,咖啡因可以为我们短暂提高我们的注意处理能力和我们的记忆力。因此,认为帮助我们的认知可能实际上会有益于修复疾病对我们的认知能力的损害似乎是合乎逻辑的。


Some studies have observed coffee drinkers over a long period of time and found that moderate coffee consumption may be associated with reduced dementia risk.

在很长一段时间内观察咖啡饮用者的一些研究发现中等的咖啡消费可能与减少患认知症的风险有关。


Unfortunately, this finding has not been consistently replicated. Other researchers have suggested that it might be the caffeine itself, rather than the coffee, that is beneficial to reducing dementia risk.

不幸的是,这一发现并没有持续地被重复出来。其他研究人员认为可能是由于咖啡因本身,而不是咖啡,有利于减少患认知症的风险的缘故。


However, a recent meta-analysis, looking at many of these observational studies, was unable to reliably link caffeine consumption with a reduced risk of developing diseases like Alzheimer’s.

然而最近的一项考察了许多这些观察性研究的荟萃分析,仍然无法可靠地将咖啡因消费与发展如阿尔茨海默症等疾病的风险的降低联系起来。


It is important to remember that coffee is a stimulant, and that too much coffee can have major ramifications for your health. Overall, its status as a protective factor against diseases like Alzheimer’s remains unclear, and certainly it represents an area where more research is needed.

重要的是要记住,咖啡是一种兴奋剂,喝太多的咖啡会严重影响你的健康。总体而言,咖啡作为对抗阿尔茨海默病等疾病的保护因子的地位仍不清楚,并且它确实代表了一个需要更多研究的领域
