The study involved 96 mice, most of which were genetically altered to develop beta-amyloid plaques and memory problems mimicking Alzheimer's disease as they aged. Some mice were left as-is, so researchers could test the effects of the radiation on normal memory as well.
Both the Alzheimer's and normal mice were exposed to the electromagnetic field generated by standard cell phone use for two 1-hour periods each day for seven to nine months.
The mice were not actually chatting on cell phone or even packing the devices. Rather, they were housed in cages arranged around a centrally-located antenna that generated a cell-phone signal. The cages were arranged at the same distance from the antenna and exposed to the radiation typically emitted by a cell phone pressed up against a human head.
Radiation and memory
Results showed if cell phone exposure was started when the Alzheimer's mice were young adults before signs of memory impairment were apparent their cognitive ability was protected. In fact, the Alzheimer's mice performed as well on tests measuring memory and thinking skills as aged mice without dementia.
If older Alzheimer's mice already exhibiting memory problems were exposed to the cell phone radiation, their memory impairment disappeared. The researchers suggest this reversal may be due to the slight increase in brain temperature that they observed in the Alzheimer's mice after months of exposure to cell phones. The higher temperature may have helped the Alzheimer's brain to remove newly-formed beta-amyloid by causing brain cells to release it.
The cell phone exposure even boosted the memories of normal mice to above-normal levels.
