In older people with mild cognitive(認(rèn)知)impairment(損害)，having a drink now and then——up to an average of one drink of alcohol each day——may delay progression to dementia(癡呆癥)，．new research suggests．

    “While many studies have assessed(評(píng)價(jià))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 didn’t drink．

    The benefit was seen with both alcohol in general and with wine in particular．
