    Doing crossword puzzles, reading, and playing cards daily may delay the rapid memory decline that occurs if people develop dementia, according to a U.S. study.

    Researchers from New York's Albert Einstein College of Medicine spent five years following 488 people aged 75 to 85 who did not have dementia at the start of the study.

    During the study period, 101 of these people developed dementia.

    At the start of the study the participants reported how often they participated in six leisure mind activities - reading, writing, doing crossword puzzles, playing board or card games, having group discussions, and playing music.

    For each activity, daily participation was rated at seven points, several days a week was rated at four points, and weekly participation was rated at one point.

    The average score for those who later developed dementia was seven points, meaning they took part in one of the six activities each day on average.

    Ten people reported no activities, and 11 reported only one activity per week.

    The researchers then looked at the point when memory loss started accelerating rapidly and found that for every additional activity a person participated in, the onset of rapid memory loss was delayed by 0.18 years.

    "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," said researcher Charles Hall in a statement.

    He said that the results remained valid after researchers factored in the education level of the participants.

    "These activities might help maintain brain vitality. Further studies are needed to determine if increasing participation in these activities could prevent or delay dementia," said Hall.

    The study, published in the journal Neurology, was supported by the National Institute on Aging.

    美国一项研究功效剖明: 天天做纵横填字游戏, 阅读和打牌有助于延缓智力衰退患者的影象力降落速率。

    纽约因斯坦医学院研究职员对488名75至85岁的康健老年人(初期未患智力衰退症)开展了为期5年的研究,

    研究历程中发明,其中101位白叟厥后徐徐患上了智力衰退症。

    研究初期,这些老年人都各自陈述请问了其介入六项年夜脑放松勾当的勾当频率,这六项勾当分袂是-阅读,誊写,做纵横填字游戏,下棋或打牌,开小组会,以及玩音乐。

    每项勾当的参预给分标准如下:天天举办一次的打7分,一周举办屡次的打4分,每周举办一次的打1分。

    研究发明,厥后患上智力衰退症的被研究器材均匀得分为7分,也便是说,他们均匀天天都举办一项勾当(上述6项勾当之一).

    据呈报,研究器材中的10人未介入任何勾当,而11人每周仅举办一次勾当。

    研究职员对影象力衰退起头加剧时段的得分情形举办剖析后发明:人们每多介入一项勾当,其影象力可延缓衰退0.18年。

    研究员Charles Hall暗示: "每周举办11项勾当可比每周仅举办4项勾当使脑力衰退延缓1.29年".

    被研究器材的教诲背景并未对研究功效造成影响。

    Hall说: "这些勾当有助于贯串毗邻年夜脑活力。有关加强参预这些勾当是否可灌注贯注或延缓智力衰退症,另有待于进一步研究".

    该项研究由美国国家老年研究所协办,并被刊登于Neurology杂志。
