More mobile phone use, or increased risk of Alzheimer's?

Alzheimer's disease (AD), commonly known as senile dementia, was first discovered and reported by a German doctor in 1906.

As a neurodegenerative disease, Alzheimer's disease is clinically manifested as progressive memory impairment, cognitive dysfunction and language impairment, etc. Patients will have aphasia, apraxia, agnosia and other symptoms, just like memory Eraser, erase the patient's memory little by little.

With the acceleration of the aging process, the number of people suffering from Alzheimer's disease is also increasing year by year. The International Alzheimer's Association estimates that by 2050, the number of Alzheimer's patients worldwide will soar to 152 million. A person develops Alzheimer's disease every 3 seconds, and the annual cost of dementia is currently estimated at $1 trillion, a figure that will double by 2030.

Although it has been more than a century since Alzheimer's disease was discovered, scientists have so far failed to find the true cause of Alzheimer's disease. But this does not mean that humans can only do nothing about Alzheimer's disease. Scientists increasingly agree that Alzheimer's disease prevention and treatment should be done as early as possible, and interventions should be implemented before symptoms such as memory loss appear.

Previously, the "Lancet" journal had published an article that about 35% of dementia patients were associated with nine risks . However, these nine risks can be reduced by: ensuring good childhood education; avoiding high blood pressure, obesity and smoking; controlling diabetes; avoiding depression and age-related hearing loss; maintaining physical activity; and staying socially active in old age.

Now, a new study from the University of Washington in the United States shows that excessive radiation from cell phones and wireless networks can also lead to early-onset Alzheimer's disease. The study found that the low-intensity electromagnetic fields of wireless communication also lead to accelerated growth of calcium ions in brain cells. Various previous experiments have shown that excess calcium ions in the brain are one of the key causative factors of Alzheimer's disease.

On this basis, the research team further studied the specific harm of excess calcium ions to the brain.

On the one hand, an increase in calcium ions leads to an increase in beta-amyloid. Its abnormal accumulation will cause neurons to lose some function, thereby causing neuronal tangles and more loss of brain function, which has a great impact on memory and cognitive function.

On the other hand, various low-intensity electromagnetic fields together activated voltage-gated calcium channels (VGCCs). Elevated calcium ion concentration produces excessive calcium signaling and hydrogen peroxide, which leads to oxidative stress, increased inflammatory cytokines, and mitochondrial dysfunction.

In the digital age, electromagnetic waves of various non-ionizing radiation seem to have become an unavoidable reality, but this at least gives us a reminder to play less mobile phones - Alzheimer's disease is not a doomed "terminal disease". A healthy lifestyle could be a shield against Alzheimer's disease, which has important implications for both individuals and society.
