There is new hope for millions of people suffering from Alzheimer's disease? Medical researchers at the University of South Florida in Tampa have in the scientific journal "Journal of Alzheimer's Disease" (vol. 19, p. 191) now published the surprising results of their study.
And this is like a sensation: Just the often demonized phone radiation to prevent or alleviate an existing Alzheimer's disease, at least - the result of a study with mice.
In healthy animals, the radiation also improved the memory. As the health effects would not be triggered, nor precisely known, write the doctors to Gary Arendash. Nevertheless, they consider their results to humans is relevant.
Scientists at the Alzheimer's Research Center of the University had included nearly 100 mice in their tests. Most of them were "mouse model for Alzheimer's, then genetically modified animals, whose brains are in the typical deposits of beta-amyloid peptide.
The mice were in cages, which were grouped around an antenna. They sent out a standard for mobile telephones electromagnetic radiation with a frequency of 918 megahertz - twice a day each for one hours, seven to nine months long. The dose of 0.25 watts per kilogram was in line of those who interact with holding down the phone to his ear to the human brain, the doctors reported.
In young, not yet infected animals were formed - in contrast to normal - during the test no beta-amyloid plaques in the brain, analysis showed. Behavioral tests revealed that her cognitive abilities were intact. In older animals with Alzheimer's disease, the physicians found that they in performance after several months of radiation therapy showed good results as well as completely healthy mice. There were fewer deposits in the brain.
And that was not all, contact the medical healthy, not genetically modified mice from the electromagnetic waves, then cut them off better in memory tests than previously.
It is assumed that the results are also relevant for humans, the researchers emphasize. Possibly would result in a new and effective Alzheimer's therapy. The cause of the effects, however, must be further investigated.
Had previously only demonstrated that the temperature of the brain in Alzheimer's mice in the experimental course, some increase. The temperature rise may support the replacement of harmful deposits, participate in the research.
The increased brain activity of healthy animals, the doctors explain the fact that by radiation, the activity of brain cells would be stimulated, the blood flow and the total energy sales were higher.
The exact mechanisms are still unclear, however, give the researchers argued. That the potential positive effects of mobile phone radiation remained hidden in the memory so far that they could be because there had been no long term studies about this, it is said in the statement of the university.
