脑子越用越灵,有研究为证

老年朋友们或许该记住要常常动动脑筋了。
Older adults might want to remember to exercise their brains regularly.
一项最新研究发现,刺激大脑运转的活动能够对老年痴呆症病发前记忆力的急速减弱起到减缓作用。
Brain-stimulating activity, according to a new study, can delay the rapid loss of memory that precedes dementia.
在长达五年的时间里,研究者跟踪调查了488名老年人,从最小75岁到最老85岁。他们在研究最开始时都没有患老年痴呆症。然后研究者记录下每周被调查者参加此类活动的次数。
For five years, researchers followed 488 adults, aged 75 to 85, who did not have dementia at the start of the study. They recorded the number of brain-stimulating activities that people participated in each week.
到研究结束时,约有五分之一的老人患上了老年痴呆。不过锻炼大脑的频率却决定了记忆力减退的早晚。
About a fifth of the participants had developed dementia by the end of the study, but the onset of memory decline appeared to vary based on the amount of mental exercise they had gotten.
刊登在8月4号《神经学》杂志上的一篇论文指出:老年人每参加一次活动,像是阅读,写作,游戏或是音乐,他或她似乎都能让记忆力减退的症状延迟两三个月发生。
Every time a senior took part in an activity such as reading, writing or playing games or music, the person appeared to delay rapid memory loss by about two to three months, the study found. A report on the study appears in the Aug. 4 issue of Neurology.
“每周参与11项活动的老人与每周仅参与4项活动的老人相比,前者记性开始加速减退的时间要晚1.29年。”在该杂志新闻发布会上,来自纽约市阿尔伯特爱因斯坦医学院的该文作者Charles B. Hall如是说。
"The point of accelerated decline was delayed by 1.29 years for the person who participated in 11 activities per week compared to the person who participated in only four activities per week," study author Charles B. Hall, of the Albert Einstein College of Medicine in New York City, said in a news release from the journal's publisher.
活动可以是阅读,写作,纵横字谜游戏,下棋,打扑克,三五成群的聊天,听音乐等等。一般而言,那些发生了老年痴呆症的调查对象一天只从事一种活动。
Activities included reading, writing, doing crossword puzzles, playing board or card games, having group discussions and playing music. On average, those who developed dementia did one activity a day.
“在晚年,这些活动的效果似乎与所受教育层次关系不大,”Hall说,“这些活动也许可以让大脑保持活跃。”
"The effect of these activities in late life appears to be independent of education," Hall said. "These activities might help maintain brain vitality."
不过Hall也认为参与此类活动是否真能延缓或预防老年痴呆症,还需要更多研究。
Hall noted, however, that further study would be needed to determine whether increasing participation in such activities might prevent or delay dementia.
