Learn about the relationship between the percentage of oxygen in the blood and the incidence of Alzheimer's .. A study reveals


A research study by scientists from the University of Sussex in Britain has found experimental evidence on why the area, which is generally referred to as the "brain memory center", is damaged and degenerated, which is a precursor to Alzheimer's disease. They attributed this to levels of oxygen in the blood that lead to memory loss, which is the early symptoms of the disease. Alzheimer's.


According to a report by the Time Now News website, scientists from the University of Sussex recorded the oxygen levels in the blood and provided experimental evidence for why the area, commonly referred to as the brain memory center, was damaged and degenerated, and it is an introduction to Alzheimer's disease to understand the cause of the sensitivity of this region, where the researchers headed by Dr. Catherine Hall of the School of Psychology and Neurosciences in Sussex studied brain activity and blood flow in the brains of mice and then the researchers used simulations to predict that the amount of oxygen provided to neurons in the brain is only sufficient for the cells to continue functioning normally.


These results are an important step in the search for preventive measures and treatments for Alzheimer's disease because they indicate that increasing blood flow in the hippocampus, "one of the areas of the brain", may be really effective in preventing damage, said Dr. Catherine Hall, senior lecturer in psychology at the University of "Sussex". It was true that increased blood flow in the hippocampus is important in protecting the brain from diseases such as Alzheimer's. This will lead to weight gain behind the importance of regular exercise and a low-cholesterol diet for long-term brain health.


She added that oxygen levels in this area of ​​the brain drop to levels that prevent neurons from working, which is most likely the reason why Alzheimer's disease first causes memory problems because the early decrease in blood flow prevents cells in the brain from working properly.



Dr. Kira Shaw, a psychology researcher at the University of Sussex who conducted the main experiments, added: "We found that blood flow and oxygen levels in the brain's hippocampus region were lower than those in the visual cortex as well. When neurons are active, there is a significant increase in blood flow and oxygen levels." In the visual cortex, this provides energy for hungry neurons, but in the hippocampus, these responses were much less. "


Scientists also found that blood vessels in the hippocampus contain fewer mRNA copies (codes for making proteins) for the proteins that make up the aneurysms.In addition, the cells that make small blood vessels, called pericytes, were different in the hippocampus than in the visual cortex.
