RIGHT OR WRONG. Are telephone waves responsible for early Alzheimer’s, as a recent study claims?

A study, published March 11 in the scientific journal Current Alzheimer’s Research, links the development of early cases of Alzheimer’s disease to excessive exposure to electromagnetic waves, particularly from cell phones or Wi-Fi.

An excess of intracellular calcium

To do this, the author, Dr. Martin L. Pall, professor of biochemistry and basic medicine at Washington State University, gathered evidence from the scientific literature and from research on rats. “Electromagnetic fields work through electric peaks and time-varying magnetic forces,” he explains.

Numerous studies have shown for several years that excess calcium in cells may be one of the factors of Alzheimer’s disease. According to Dr. Martin L. Pall exposure to magnetic waves generates 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 causes 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

However, when asked about this study, Sandrine Andrieu, president of the scientific council of “France Alzheimer” and professor of public health in Toulouse, calls for caution. “We cannot make any announcements based on this publication, says the scientist. First of all, the study is based on research in rats. And often there’s a discrepancy between what’s found in animals and what’s more, the study only has one author, which is quite surprising.”

Another problem: the researcher has made a synthesis of other articles here, without explaining his selection method. “So it’s possible he only took articles that interested him and went in the direction of his thinking. There may be a bias of subjectivity.”

Especially since few serious studies seem to have established a link between electromagnetic fields and Alzheimer’s disease. “There have always been articles on the effect of the cell phone, with tumors in its place. Based on Alzheimer’s disease, I don’t know, although I haven’t researched it. The subject,” says Sandrine Andrieu.

Alzheimer’s risk decreases

And are there really more cases of early Alzheimer’s than before? “Today we have a lot more attention. People ask themselves a lot more questions than before when they detect a condition. Indeed, much more work is now being done on young Alzheimer’s, but the detection is much better. Perhaps some have gone unnoticed for. the extreme ages, i.e. before 50 years and after 80 years, there are few subjects, therefore a great variability of results, and thus difficult to draw a conclusion about 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 certain age group, is lower than before. The reasons given? A better level of education and better control of cardiovascular risk factors in particular. “We don’t have fewer cases at the population level. As the population ages, more and more people are entering the risk phase, so we have more cases mathematically. However, the risk to a particular individual, at a particular age, seems less important these days.” .
