Cellular phone radiation triggers ADHD-like symptoms
Radiation in the womb leads to brain and behavioral changesRead out
Cellular phone radiation could interfere with the brain development of unborn children in the womb. Evidence has been found by researchers in experiments with mice. If they exposed pregnant mouse mice to the electromagnetic radiation of a mobile phone, their boys later developed behavioral disorders. These would have been similar to those of human children with attention deficit ADHD. The mice exposed in the womb of the radiation are hyperactive, less anxious and would have shown memory problems, the researchers report in the scientific journal "Scientific Reports".
Radiation exposure in the womb also triggered physiological changes in the brain of the mouse, as the scientists observed. This disrupted the transmission of the brain messenger glutamate in these animals. Most affected by these changes is the so-called prefrontal cortex, a brain center that also plays an important role in ADHD, the researchers say.
Pathological changes in brain functions
"This is the first experimental demonstration of pathological changes in brain function caused by exposure to womb-to-mobile radiation, " write Tamir Aldad of Yale University, New Haven, and colleagues. It is not surprising that similar effects have not yet been found in studies with adult animals. Because the unborn child's brain is particularly sensitive to environmental influences.
The effects observed in mice can not simply be transferred to humans, the researchers emphasize. But even in humans, it is known that during the development of the fetus there are critical time windows in which the brain is particularly sensitive to environmental influences. "We now need more experiments to find out if human radiation exposure poses a risk to the human body, " say Aldad and his colleagues.
Cellphone on the mouse cage
For their study, the researchers had held 53 pregnant female mice in cages, on top of which a mobile phone was attached. In the control group, this phone remained off. The mobile phone emitted radiation with a specific absorption rate (SAR) of less than 1.6 watts per kilogram (W / kg). The legal upper limit in the European Union is 2 W / kg. display
The researchers subjected the offspring of all mouse worms to several tests, which were repeated at intervals of several weeks. The animals' memory, anxiety and activity were tested. Significant differences between irradiated and unirradiated mice have been found in all tests, say the scientists. Further tests also revealed the underlying neurophysiological differences.
