Alcohol use was assessed before the survey. 　　Drinking was not associated the development of mild cognitive impairment, according to the report. However, once mild impairment occurred, subjects who had up to one drink per day of alcohol had an 85 percent reduced risk of dementia compared with those who abstained. 　　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 isnt known. However, it is possible that the arrangement of blood vessels in the brain may play a role, Solfrizzi and Panza conclude. 　　有轻度认知损害的老年人可以喝点酒，一项必威体育精装版研究发现，每天喝点酒可以延缓病情向痴呆症的发展。 　　研究报告撰写者、意大利巴里大学的温森佐·索尔弗里兹博士和弗朗西斯科·潘萨博士在一份声明中说：“此前有很多研究对老年人饮酒与认知功能间的关系进行过探讨，而此项研究则首次对饮酒会如何影响轻度认知损害向痴呆症的发展速度进行了探究。” 　　此项研究结果在《神经学》医学期刊上发表。研究人员对1445名研究对象中轻度认知损害的发生及121名有轻度认知损害的病人向痴呆症的发展进行了研究。
