Researchers exposed genetically modified Alzheimer's mice to 1950 MHz radiofrequency radiation (similar to cell phone frequencies) for 3 months to see if it worsened memory problems. The EMF exposure did not make memory deficits worse or increase harmful brain protein deposits. This suggests cell phone radiation may not accelerate Alzheimer's-like brain damage, at least in this animal model.
