A study published on Wednesday in the journal Neurology showed stressed-out middle-aged people were more likely to show symptoms of memory loss. The study revealed that middle-aged people with high levels of a hormone called cortisol in their blood have apparently impaired memory when compared to those with average levels of the hormone. 周三于《神经病学》期刊上发布的一篇研究表明：备受压力的中年人更易出现健忘症状。该研究表明：与血液中皮质醇激素水平处于平均值的中年人相比，该激素水平更高的中年人记忆力明显受损。 Cortisol, produced by the adrenal glands, helps the body respond to stress and it can also help reduce inflammation, control blood sugar and blood pressure. High cortisol levels can be caused by stress, medical conditions or medications. 皮质醇由肾上腺产生，有助于身体对压力做出反应，同时有助于消炎、控制血糖和血压。高的皮质醇水平可能是由于压力、医疗条件或药物引起的。 "Cortisol affects many different functions so it is important to fully investigate how high levels of the hormone may affect the brain," said the study's author Justin B. Echouffo-Tcheugui with Harvard Medical School. "皮质醇影响许多不同的功能，所以对皮质醇的水平会如何影响大脑进行充分研究是非常重要的，"来自哈佛医学院的研究作者Justin B. Echouffo-Tcheugui说道。 |
