View Original AbstractCell phone frequency EMF reversed Alzheimer's brain damage in mice, suggesting therapeutic potential at everyday exposure levels.
Plain English Summary
Researchers exposed very old mice with Alzheimer's-like brain damage to cell phone frequency radiation (978 MHz) for two months. The EMF treatment actually reversed the buildup of toxic brain plaques and improved memory function without causing brain heating. This suggests that certain electromagnetic frequencies might help break down the protein clumps that characterize Alzheimer's disease.
Why This Matters
This study challenges conventional thinking about EMF exposure and brain health. While most research focuses on potential harm from wireless radiation, this work by Arendash and colleagues demonstrates that specific EMF frequencies might actually provide therapeutic benefits for neurodegenerative conditions. The 978 MHz frequency used here is very close to cell phone frequencies (around 850-1900 MHz), operating at power levels similar to what your phone produces. What makes this particularly significant is that the cognitive improvements occurred without brain heating, the mechanism regulators claim is the only way EMF can affect biology. The researchers found that EMF treatment broke apart the amyloid plaques that define Alzheimer's pathology and enhanced memory function in both diseased and healthy aging mice. This adds to a growing body of evidence that EMF bioeffects extend far beyond simple thermal heating, supporting the need for exposure standards that account for non-thermal mechanisms.

Study Details
Few studies have investigated physiologic and cognitive effects of “long-term" electromagnetic field (EMF) exposure in humans or animals. Our recent studies have provided initial insight into the long-term impact of adulthood EMF exposure (GSM, pulsed/modulated, 918 MHz, 0.25–1.05 W/kg) by showing 6+ months of daily EMF treatment protects against or reverses cognitive impairment in Alzheimer's transgenic (Tg) mice, while even having cognitive benefit to normal mice. Mechanistically, EMF-induced cognitive benefits involve suppression of brain β-amyloid (Aβ) aggregation/deposition in Tg mice and brain mitochondrial enhancement in both Tg and normal mice. The present study extends this work by showing that daily EMF treatment given to very old (21–27 month) Tg mice over a 2-month period reverses their very advanced brain Aβ aggregation/deposition.
These very old Tg mice and their normal littermates together showed an increase in general memory fu...
These results demonstrate that long-term EMF treatment can provide general cognitive benefit to very old Alzheimer's Tg mice and normal mice, as well as reversal of advanced Aβ neuropathology in Tg mice without brain heating. Results further underscore the potential for EMF treatment against AD.
