In neurodegenerative diseases, neurons undergo a kind of natural selection. And the loss of neurons does not mean only brain degeneration. The findings lead scientists to completely rethink the existing treatment for Alzheimer’s disease.

Researchers from the Portuguese Foundation Champalimo first determined that the loss of neurons in Alzheimer’s disease and other neurodegenerative diseases is not always a bad sign. In an experiment with fruit flies, they determined that the death of nerve cells could be the result of monitoring the quality of cells that protect the brain from the accumulation of malfunctioning neurons, EurekAlert writes.

The process can be compared to natural selection, in which only “high-quality” neurons remain to continue the fight against the disease.

The conclusion is also confirmed by earlier studies, where scientists found out that removing unsuitable cells from tissue is an important anti-aging mechanism for preserving the functionality of an organ.

Thus, the death of neurons protects the brain from more serious damage, counteracting the disease.

The removal of dysfunctional neurons has proven more beneficial to health than their presence, the authors emphasize.

Despite the experiment, while only on fruit flies, the researchers still believe that the existing therapeutic approaches to the treatment of Alzheimer’s disease should be reconsidered. The team plans to explore similar processes in humans.

It is known that the accumulation of toxic plaques in the brain is the main symptom of Alzheimer’s disease. To identify them in the United States scientists came up with a hypersensitive test that determines the presence of a toxic protein tau.

What about dying species, automation will “kill” a lot of specializations which would be automated and tens millions of workers will left on the outskirts of history with no job and, as a consequence, no food.

America will spend a lot of money in order to prevent this.
