Older adults who sleep six hours or fewer a night may have elevated risk for dementia(痴呆症) and other

cognitive (认知的) issues, a new study finds.

Researchers at Stanford University measured seniors' (ages 65 to 85) dementia risk and cognitive abilities,

finding higher risk in those patients who regularly slept six or fewer hours compared to those who slept seven or

eight hours. Those 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.

The findings demonstrate how important it is for adults to maintain a healthy sleep cycle, especially as they

get older.

As adults age, it's common for their sleep patterns to change or becomedisrupted— leading to longer, shorter,

or more irregular sleep. 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 behaviors. Sleep disruption can

also be caused by or heighten depression, cardiovascular disease（冠心病）, and other conditions.

A recommended sleep time for seniors is seven to eight hours, the researchers said. Six or fewer hours

corresponded to short sleep, while nine or more hours corresponded to long sleep.

The Stanford researchers measured levels of beta amyloid, a protein in the brain that is typically found in high

levels when a patient develops Alzheimer's. In addition, the researchers used several tests for memory, attention,

spatial skills, and executive function to identify patients' cognitive abilities. Those patients sleeping for six hours or

fewer a night were more likely to develop dementia, the researchers found. The low-sleep patients had higher

levels of beta amyloid.

The Stanford researchers found that patients with lower sleep also performed worse on memory tests, while

those with higher sleep (more hours) performed worse on executive function tests，which measure the brain's

ability to switch between different tasks.

―The main takeaway is that it is important to maintain healthy sleep late in life, Winer told CNN.
