  • Sleep deprivation1 may raise the risk of getting Alzheimer's disease.

    睡眠不足可能会增加罹患阿尔茨海默病的风险。

    Just one sleepless2 night has been found to cause the build-up of a protein linked to the devastating3 condition.

    研究发现,通宵熬夜一天就会引起与这种可怕疾病有关的一种蛋白质的增长。

    A night without sleep increased the beta-amyloid protein in part of the brain.

    通宵熬夜会增长大脑部分区域中的乙型淀粉样蛋白的含量。

    People with mild memory loss have 21 per cent more beta-amyloid in their brains than healthy elderly people, while those with Alzheimer's disease have 43 per cent more beta-amyloid.

    患有轻度记忆丧失症的人,其大脑中的乙型淀粉样蛋白的含量比健康老年人的要高21%,而那些患有阿尔茨海默病的人,其大脑中的乙型淀粉样蛋白的含量则要比健康的老年人高43%。

    Sleep is vital in clearing away beta-amyloid, which can form clumps4 in the brain to block important pathways for memory.

    睡眠对清除乙型淀粉样蛋白至关重要,而这种蛋白能在大脑中结块并阻塞记忆的重要通道。

    Dr Ehsan Shokri-Kojori said: 'The increase in beta-amyloid in the brains of people who were sleep-deprived is likely to be a harmful process.

    艾森·肖克里-科杰里博士表示:“睡眠不足的人大脑中增加乙型淀粉样蛋白的过程可能是有害的。

    'A reasonable prediction based on the results would be that poorer sleep habits create a risk for Alzheimer's disease.'

    “基于该结果的合理预测是,不良的睡眠习惯会造成罹患阿尔茨海默病的风险。”

    Sleep may play an important role in a natural 'waste disposal' system that clears potentially harmful material including amyloid-beta out of the brain, scientists believe.

    科学家相信,睡眠可能在人体正常的“废物处理”系统中发挥着重要的作用,它可能会清除大脑中乙型淀粉样蛋白等有害物质。

    Dr David Reynolds said: 'The study suggests that one night of sleep deprivation can raise levels of the hallmark Alzheimer's protein amyloid, strengthening suggestions that sleep is important for limiting the build-up of this protein in the brain.'

    大卫·雷诺兹博士表示:“研究表明,通宵熬夜一天可能会增加阿尔茨海默病标志性淀粉样蛋白的含量,这进一步表明睡眠对于抑制大脑中这种蛋白质的增长十分重要。”
