  • About one million people are affected by Alzheimer’s disease in France.
  • It is rare in people under 65 years of age.
  • For 20 years, the age of onset of the disease has been declining. Some cases are detected between 30 and 40 years.

Although Alzheimer’s disease was identified in the early 20th century, its exact causes are still difficult to identify. Only 1.2 to 2% of cases are hereditary according to Inserm. Recently, an American researcher became interested in potential environmental causes. In works published in Current Alzheimer’s research, Martin L. Pall, professor emeritus of biochemistry and medicine at the University of Washington, develops the theory of an association between electromagnetic fields and the early onset of disease. However, they are increasingly present in our daily lives, via the electronic devices we use.

Effects on intracellular calcium levels

The link between these electromagnetic fields and Alzheimer’s disease comes from calcium: For almost 25 years, scientists have been interested in the effects of this chemical element on pathology. Studies have shown that an excess of calcium in the cells can be the cause of Alzheimer’s disease. The accumulation of calcium in the cells leads to various changes in the brain, two of which are conducive to the development of the disease. First, it generates an increase in amyloid precursor protein aggregates, which then form amyloid plaques in the brain. It can also lead to various less specific neurodegenerative changes, such as those on tau protein, oxidative stress, and inflammation. Gold, electromagnetic fields act on our cells by activating voltage-gated calcium channels (VGCC). Their activation causes a rapid increase in intracellular calcium levels. “Therefore, EMF exposures produce changes that lead to excess intracellular calcium, develops the author of the study. This accumulation explains the effects on the brain of Alzheimer’s disease.

Increased exposure to electromagnetic fields

However, electronically generated pulsed electromagnetic fields (EMF) are widely used for wireless communication and produce strong electric and magnetic waves. Previous studies, performed on animal models, have shown their effect on intracellular calcium levels and on the brain. “Electromagnetic fields act via electrical tips and time-varying magnetic forcess, says Professor Pall. These peaks have increased significantly, with each increase in pulse modulation produced by smarter mobile phones, smart meters, smart cities and radars in autonomous vehicles. ” In his latest study, he gathers evidence, taken from the scientific literature, which shows the link between these EMFs and the early onset of the disease. Among them, 12 recent assessments of occupational exposure to EMFs revealed that there is a higher incidence of disease in persons occupationally exposed to these areas. Other research on rats showed that exposure to electromagnetic pulses generated neurodegeneration.

The need for further research

Very young people who are exposed to radiation from mobile phones or Wi-Fi for several hours a day can develop digital dementia. “, says Martin L. Pall. According to him, it is urgent to continue research on this topic.“The results of each of these studies should be shared with the general public.believes Martin L. Pall, so everyone can take the necessary steps to reduce the incidence of early forms of Alzheimer’s disease“.
