Long term cell phone usage may not only prevent Alzheimer's, it may even reverse some of the effects of the disease, a new study was quoted as saying by media reports Sunday.

    In mice prone to an animal form of Alzheimer's disease, long-term exposure to electromagnetic radiation typical of cell phones slowed and reversed the course of the illness, according to the study conducted by researchers from the University of South Florida in the Unitd States.

    The findings provide "striking evidence for both protective and disease-reversing effects" of long-term exposure to radiation at cell phone levels, researchers said.

    The study also suggested that even the "normal" mice showed improved memory cognition.

    But some experts cautioned that the science in the study is still very early.

    Alzheimer's disease affects 1 in 10 adults over the age of 55. Previous data has shown that every 5 years after the age of 60, the odds for developing Alzheimer's disease doubles.

    星期天媒體引用一項(xiàng)新的研究成果說，長(zhǎng)期使用手機(jī)不僅可預(yù)防老年癡呆癥，而且能扭轉(zhuǎn)該病的某些影響。

    根據(jù)由美國(guó)南弗洛里達(dá)大學(xué)研究人員進(jìn)行的研究，有動(dòng)物形式的老年癡呆癥傾向的實(shí)驗(yàn)鼠，長(zhǎng)期接觸典型的手機(jī)電磁輻射延緩并扭轉(zhuǎn)了病程。

    研究人員說，這項(xiàng)研究成果為長(zhǎng)期接觸手機(jī)劑量水平的電磁輻射具有保護(hù)作用和疾病改善作用提供了令人震驚的證據(jù)。

    研究還指出，即使"正常"的實(shí)驗(yàn)鼠記憶認(rèn)知力也有改善。

    但有些專家警告說，研究的學(xué)科仍在初期。

    55歲以上的人中，10人中有1人患老年癡呆癥。先前的數(shù)據(jù)已經(jīng)表明，60歲以后，每過五年患老年癡呆癥的機(jī)率翻一翻。
