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.

星期天媒体引用一项新的研究成果说，长期使用手机不仅可预防老年痴呆症，而且能扭转该病的某些影响。

根据由美国南弗洛里达大学研究人员进行的研究，有动物形式的老年痴呆症倾向的实验鼠，长期接触典型的手机电磁辐射延缓并扭转了病程。

研究人员说，这项研究成果为长期接触手机剂量水平的电磁辐射具有保护作用和疾病改善作用提供了令人震惊的证据。

研究还指出，即使"正常"的实验鼠记忆认知力也有改善。

但有些专家警告说，研究的学科仍在初期。

55岁以上的人中，10人中有1人患老年痴呆症。先前的数据已经表明，60岁以后，每过五年患老年痴呆症的机率翻一翻。
