There’s a great deal of public paranoia surrounding the possible side effects of cell phone use on our fragile little brains. Now there’s a study to get excited about which has shown that mice with Alzheimer’s that were exposed to the common 900 MHz mobile phone band radiation (918 MHz; 250 mW/kg) actually performed better in cognitive tests than those without exposure. The researchers from University of South Florida’s Alzheimer’s Disease Research Center are now conducting further tests using other frequency and power setting to narrow down which settings produce the greatest benefit to the mice.
Here’s the abstract of the article in the Journal of Alzheimer’s Disease:
Despite numerous studies, there is no definitive evidence that high-frequency electromagnetic field (EMF) exposure is a risk to human health. To the contrary, this report presents the first evidence that long-term EMF exposure directly associated with cell phone use (918 MHz; 250 mW/kg) provides cognitive benefits. Both cognitive-protective and cognitive-enhancing effects of EMF exposure were discovered for both normal mice and transgenic mice destined to develop Alzheimer’s-like cognitive impairment. The cognitive interference task utilized in this study was designed from, and measure-for-measure analogous to, a human cognitive interference task. In Alzheimer’s disease mice, long-term EMF exposure reduced brain amyloid-β (Aβ) deposition through Aβ anti-aggregation actions and increased brain temperature during exposure periods. Several inter-related mechanisms of EMF action are proposed, including increased Aβ clearance from the brains of Alzheimer’s disease mice, increased neuronal activity, and increased cerebral blood flow. Although caution should be taken in extrapolating these mouse studies to humans, we conclude that EMF exposure may represent a non-invasive, non-pharmacologic therapeutic against Alzheimer’s disease and an effective memory-enhancing approach in general.
