    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.

    美國(guó)一項(xiàng)研究結(jié)果表明: 每天做縱橫填字游戲, 閱讀和打牌有助于延緩智力衰退患者的記憶力下降速度。

    紐約愛(ài)因斯坦醫(yī)學(xué)院研究人員對(duì)488名75至85歲的健康老年人(初期未患智力衰退癥)開(kāi)展了為期5年的研究,

    研究過(guò)程中發(fā)現(xiàn),其中101位老人后來(lái)逐漸患上了智力衰退癥。

    研究初期,這些老年人都各自匯報(bào)了其參加六項(xiàng)大腦放松活動(dòng)的活動(dòng)頻率,這六項(xiàng)活動(dòng)分別是-閱讀,書(shū)寫(xiě),做縱橫填字游戲,下棋或打牌,開(kāi)小組會(huì),以及玩音樂(lè)。

    每項(xiàng)活動(dòng)的參與給分標(biāo)準(zhǔn)如下:每天進(jìn)行一次的打7分,一周進(jìn)行幾次的打4分,每周進(jìn)行一次的打1分。

    研究發(fā)現(xiàn),后來(lái)患上智力衰退癥的被研究對(duì)象平均得分為7分,也就是說(shuō),他們平均每天都進(jìn)行一項(xiàng)活動(dòng)(上述6項(xiàng)活動(dòng)之一).

    據(jù)報(bào)告,研究對(duì)象中的10人未參加任何活動(dòng),而11人每周僅進(jìn)行一次活動(dòng)。

    研究人員對(duì)記憶力衰退開(kāi)始加劇時(shí)段的得分情況進(jìn)行分析后發(fā)現(xiàn):人們每多參加一項(xiàng)活動(dòng),其記憶力可延緩衰退0.18年。

    研究員Charles Hall表示: "每周進(jìn)行11項(xiàng)活動(dòng)可比每周僅進(jìn)行4項(xiàng)活動(dòng)使腦力衰退延緩1.29年".

    被研究對(duì)象的教育背景并未對(duì)研究結(jié)果造成影響。

    Hall說(shuō): "這些活動(dòng)有助于保持大腦活力。有關(guān)加強(qiáng)參與這些活動(dòng)是否可防止或延緩智力衰退癥,還有待于進(jìn)一步研究".

    該項(xiàng)研究由美國(guó)國(guó)家老年研究所協(xié)辦,并被刊登于Neurology雜志。
