老年人睡眠差加速大腦退化

Older adults who sleep six hours or fewer a night may have elevated risk for dementia and other cognitive issues, a new study finds.

一項新研究發(fā)現(xiàn)，每晚睡眠時間不足6個小時的老年人患癡呆癥和其他認知障礙的風險會增高。

Researchers at Stanford University measured the dementia risk and cognitive abilities of seniors ages 65 to 85, finding higher risk in patients who regularly slept six or fewer hours compared to those who slept seven or eight hours.

斯坦福大學的研究人員通過對年齡在65歲到85歲之間的老年人的癡呆風險和認知能力測評發(fā)現(xiàn)，平時睡眠不足6個小時的人相比睡7個或8個小時的人癡呆風險更高。

Seniors who slept nine or more hours also had lower cognitive functions and other health issues, but the researchers didn't find the same high dementia risk in this group.

平時睡9個小時以上的人也出現(xiàn)了認知能力低下和其他健康問題，但是研究人員發(fā)現(xiàn)該群體的癡呆風險不像睡眠不足的人群這么高。

This disruption may be linked to Alzheimer's and other forms of dementia, impacting seniors' ability to remember information, problem-solve, and go through everyday tasks.

睡眠紊亂可能和老年癡呆癥或其他類型的癡呆癥有關，影響著老年人記憶信息、解決問題的能力，并會影響日常行為。

Sleep disruption can also be caused by - or heighten - depression, cardiovascular disease, and other conditions.

睡眠紊亂還可能由抑郁癥、冠心病和其他疾病導致或加劇這些病癥。
