In older people with mild cognitive(认知)impairment(损害)，having a drink now and then-up to an average of one drink of alcohol each day-may delay progression to dementia(痴呆症)，new research suggests．
“While many studies have assessed(评价)alcohol consumption and cognitive function in the elderly，this is the first study to look at how alcohol consumption affects the rate of progression of mild cognitive impairment to dementia,”study authors Dr．Solfrizzi and Dr．Panza, from the University of Bari in Italy, said in a statement．
In the study, reported in the medical journal Neurology, the researchers assessed the occurrence of mild cognitive impairment in 1,445 subjects and progression to dementia in 121 patients with mild cognitive impairment．
The participants were between 65 and 84 years of age at the start of study, and they were followed for 3.5 years．Alcohol use was assessed before the survey．
Drinking was not associated with the development of mild cognitive impairment, according to the report．However, once mild impairment occurred．Subjects who had one drink per day of alcohol had an 85 percent reduced risk of dementia compared with those who abstained(戒绝)．
The benefit was seen with both alcohol in general and with wine in particular．
Having more than one drink a day, however, offered no protection against dementia compared with abstaining, the report indicates．
“The mechanism responsible for why low alcohol consumption appears to protect against the progression to dementia isn’t known．However, it is possible that the arrangement of blood vessels in the brain may play a role,”Solfrizzi and Panza conclude．

Once upon a time the colors of the world started to quarrel．Green said,“Clearly I am the most important．I am the sign of life and hope．I was chosen for grass, trees and leaves．Without me, all animals would 1 ．”
Blue interrupted,“You only think about the 2 , but consider the sky and the sea． 3 the water that is the basis of life and drawn up by the clouds from the deep sea．Without my peace, you would all be 4 ．”
Yellow chuckled(笑道),“You are all so serious．I bring laughter, fun, and 5 into the world．”
Orange started next to blow her trumpet,“I am the color of health and strength．I may be 6 , but I am precious for I serve the needs of human life．When I fill the sky 7 , my beauty is so striking that no one gives another 8 to any of you．”
Red could stand it 9 and he shouted out,“I am the ruler of all of you．I am the color of danger and of bravery．I am willing to 10 truth．I am also the color of passion and of love．”
Then came Purple and Indigo(深蓝)…．
The colors went on boasting, each convinced of his or her own 11 ．Their quarreling became louder and louder．Suddenly there was a startling flash of bright lightening thunder．Rain started to pour down 12 ．The colors crouched(蜷缩)down 13 , drawing close to one another for comfort．
In the midst of the clamor(叫嚷), rain began to speak,“You foolish colors, fighting 14 yourselves, each trying to dominate 15 ．Don't you know that you were each made for a special purpose, 16 ?Join hands with 17 and come to me．”
Doing as they were told, the colors 18 and joined hands．They formed a colorful rainbow．From then on, whenever a good rain 19 the world, a rainbow appears in the sky．They remember to 20 one another．
