For the first time, Australian scientists have demonstrated the dependence of dietary patterns on the risk of developing Alzheimer's disease, a brain disease that is manifested by a decrease in mental performance and personality disorders. The researchers carried out the experiments on mice, writes the journal PLoS Biology.
It is noted that scientists were aware of the effect of amyloid plaques accumulating in brain tissues on the formation of Alzheimer's disease. However, it was not known where this beta-amyloid comes from and why it is deposited in the brain.
Therefore, Australian researchers have developed a mouse model in which human beta-amyloid is produced in liver cells. It was then transferred to the brain through the blood. And the mice demonstrated the development of neurodegeneration and brain atrophy.
This discovery shows that the abundance of toxic protein deposits in the blood influences the development of Alzheimer's disease. But it can potentially be eliminated with a low-fat diet and some drugs that, by acting on lipoprotein amyloid, slow the progression of the disease.
As the site kp.ru previously wrote, doctors from Tomsk are embarking on a large study on the effect of a new coronavirus infection on the mental activity of a person who has had this disease.
