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新的研究成果說，長期使用手機不僅可預防老年癡呆癥，而且能扭轉該病的某些影響。

    根據由美國南弗洛里達大學研究人員進行的研究，有動物形式的老年癡呆癥傾向的實驗鼠，長期接觸典型的手機電磁輻射延緩并扭轉了病程。

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

    研究還指出，即使"正常"的實驗鼠記憶認知力也有改善。

    但有些專家警告說，研究的學科仍在初期。

    55歲以上的人中，10人中有1人患老年癡呆癥。先前的數據已經表明，60歲以后，每過五年患老年癡呆癥的機率翻一翻。
