Bonjour,
une étude récente tend à montrer l'effet bénéfique des ondes de téléphone portable sur la maladie d'Alzheimer (et plus généralement sur la mémoire) chez la souris et donc peut-être chez l'homme.
Dans le papier scientifique (pdf 2Mo) ils écrivent :
Un résumé ici: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.

In view of these and our present findings, we propose that only long-term EMF exposure may provide consistent and significant cognitive benefits to humans at cell phone level EMF strengths. Second, we propose that such EMF exposure may have the capacity to enhance cognitive function in normal, non-demented individuals. To date, there is no evidence that “high frequency” electromagnetic fields, such as those emitted by cell phones, affect the risk of AD. Indeed, the present study provides striking evidence for both protective and disease-reversing effects of long-term EMF exposure, and at cell phone-level intensities.

Ironically, we began these studies with the hypothesis that long-term EMF exposure would be deleterious to cognitive function ...

Qu'en pensez vous ?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-beta (Abeta) deposition through Abeta anti-aggregation actions and increased brain temperature during exposure periods. Several inter-related mechanisms of EMF action are proposed, including increased Abeta 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.
