Australian scientists have made significant progress in the study of age-related degeneration of the brain. Experts have concluded that in the sunset of life in his brain processes can occur, causing an imbalance of metals necessary for the normal operation of this body. As a result, the brain just starts to rust.
According to the study authors, employees of the University of Melbourne, for the normal functioning of the human brain requires a high concentration of metals which it uses for electric reactions - in particular, iron and zinc. However, approximately 10% of people older than 60 years in the healthy functioning of the brain occur adverse effects associated with an imbalance of metals: their brain ceases to properly "processed" zinc and iron.
Why does the human brain suddenly ceases to fully absorb the metals, as he did before, scientists still can not answer. They could only find out that the imbalance of metal occurs in the brain in the case where it accumulates too much zinc. Excess zinc leads to incorrect distribution of the iron is concentrated in the gray matter, resulting in oxidative stress and destroy neurons. Simply put, the brain rusts, and the result of this process is the development of Alzheimer's disease.
At the moment, scientists are working to develop the drug with which it will be possible to normalize the balance of metals in the brain, in the hope that they will be able to win a degenerative brain disease that leads to dementia. (READ MORE)
