Earlier studies stated that exposure to cell phone radiations for more than 10 years could increase the chances of getting brain tumor. But, a recent study negating this belief said cell phone radiations could treat Alzheimer's disease or act as a preventive measure for the disease.

Researchers from University of South Florida conducted a study on 96 mice. They were genetically modified that enabled them to develop Alzheimer’s disease. All animals for two one-hour sections were exposed to the radiation for seven to nine months every day.

"It surprised us to find that cell phone exposure, begun in early adulthood, protects the memory of mice otherwise destined to develop Alzheimer's symptoms," said Gary Arendash Ph. D., lead author of the study published today in the Journal of Alzheimer's Disease.

Researchers were further surprised to notice that in older Alzheimer’s mice impaired memory was reversed after they were treated at the electromagnetic wavelengths.

A health observer however issued warnings that following this study people should not resort to cell phones as a means to treat the disease. He also said that it would be interesting to see over a period of time that how many people in the U. S. get the disease as almost everyone uses a cell phone now.
