TRUE OR FALSE. Are phone waves responsible for early Alzheimer’s, as a recent study claims?

A recent study establishes a link between smartphones and other wifi networks and the risk of early development of Alzheimer’s disease. The Midi broadcast make the point.

A study, published March 11 in the scientific journal Current Alzheimer’s research, establishes a link between the development of early cases of Alzheimer’s disease and overexposure to electromagnetic waves, especially from mobile phones or wifi.

An excess of intracellular calcium

To do this, its author, Dr. Martin L. Pall, professor of biochemistry and basic medicine at Washington State University, collected evidence, taken from the scientific literature as well as research conducted on rats. “Electromagnetic fields act through electrical tips and time-varying magnetic forces,” he explains.

For several years, numerous studies have shown that an excess of calcium in the cells may be one of the factors for Alzheimer’s disease. According to Dr. Martin L. Pall generates exposure to magnetic waves an increase in calcium levels in neuronal cells by activating voltage-gated calcium channels (pumps present in the cell walls of neurons).

“Exposure to electromagnetic fields produces changes that lead to an excess of intracellular calcium. This accumulation explains the effects on the brain in Alzheimer’s disease,” says the scientist.

A possible subjectivity bias

Asked about this study, however, Sandrine Andrieu, chair of the France Alzheimer’s Scientific Council and professor of public health in Toulouse, calls for caution. “It is not on the basis of this publication that we can make announcements,” says the scientist. First of all, the study is based on research conducted on rats. And often there is a discrepancy between what is found in animals and humans. In addition, the study has only one author, which is quite surprising. “

Another problem: the researcher has here made a synthesis of other articles without explaining his selection methodology. “So it is possible that he just took articles that interested him and that went in the direction of his mindset. There may be a bias of subjectivity.”

Especially since few serious studies already seem to have made a connection between electromagnetic fields and Alzheimer’s. “There have always been articles about the effects of the cell phone, with tumors instead. From Alzheimer’s disease, I do not know about it, even though I have not researched it. The subject,” says Sandrine Andrieu.

The risk of developing Alzheimer’s decreases

And are there really more cases of early Alzheimer’s than in the past? “Today we have a lot more attention. People are asking themselves a lot more questions than before when they perceive a disorder. There is actually a lot more work being done on young Alzheimer’s, but the discovery is much better. Maybe some went unnoticed. Before. In the extreme ages, ie before 50 years and beyond 80 years, there are few topics, therefore great variation in results, and thus difficult to conclude on these age groups “.

What is certain is that today large epidemiological studies show that the incidence of Alzheimer’s disease, in other words the number of new cases in a given age group, is lower than before. The reasons given? A better level of education and better management of cardiovascular risk factors in particular. “We do not have fewer cases at the population level. As the population gets older, we have more and more people entering the risk phase, so we have mathematically more cases. But the risk to a given individual, at a given age, seems less important in day”.
