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.

Everyone can be angry. But if you take the time to actually examine your anger instead of just “feeling” angry, you’ll have a better understanding of yourself. Knowing why you feel so angry can provide you with some surprising answers. These answers can enable you to suddenly grow spiritually and mentally.

I can give you a personal example. I went to a meeting once and I was verbally attacked over an application I supported at my workplace. Various people went on and on about how terrible this system was and that it never worked. That didn’t bother me that much. I was used to that but one of the comments that was said was, “Your job is pointless.” This really upset meand at the time, I was ly furious(发怒地) with that comment.

I was so angry and upset that they would treat me that way. Once I took the time to think about what was really making me so mad. I learned a lot. I realized that the comment was more truethan I wanted to admit. In the big scheme of things, my job was pointless. It wasn’t what I really wanted to be doing with my life and this was what frustrated me the most. Here I was pouring part of my heart and soul into a job I didn’t even really want to do. I was using it as a crutch(拐杖) because I didn’t have the confidence in myself to take the scary road towards what I really wanted to do. As soon as I realized that, a lot of my anger just melted away. I also realized that I needed to start focusing on what I really wanted to do.

I now consider this incident as a great gift It got me back on track to moving in the direction I wanted to go with my life. I probably wouldn’t be where I am today if I hadn’t taken the time to figure out why I was really so angry.
