Brain-health drugs may reduce alpine disease

effects of thin air are not limited to the body.

, more and more people are visiting high-altitude areas, whether for work, sports, religious pilgrimages, or military missions. However, even the most physically robust people suffer from thin air: lower oxygen levels can have cognitive effects, including memory loss and difficulty concentrating.
in preventing these symptoms, there is little people can do but adapt. However, adaptation takes time and does not always work. A drug called oxalasitan may solve the problem.
researchers took the troops to an altitude of 4,000 meters. Everyone lives in a town about 1,800 meters above sea level. During the study, they stayed at the altitude for eight days, then climbed for three days and reached an altitude of 4,000 meters. There, they stayed for a month.
the first 15 days of the study, 20 percent of the participants took 800 milligrams of oxytam three times a day. At the same time, another 20 per cent of the subjects did not accept any intervention. These people took attention and memory tests at the beginning and end of the study.
study found that all participants experienced cognitive decline at an altitude of 4,000 meters. However, those who took oxalasitam showed much smaller declines than the control group. Using a technique that measures the brain's response to sound, the researchers found that participants who took the drug also showed a smaller decline in the speed at which they processed sensory information.
blood flow measurements show that at high altitudes, specific parts of the brain circulation system contract and expand in a way that causes blood to flow to the brain drain. This is not surprising, as the brain is playing a key role in the maintenance of basic life characteristics.
study also found that the cost of receiving blood from the brain's brain is damage to the brain region responsible for more advanced cognitive function. However, for those taking oxytaine, more arteries dilation, resulting in increased blood flow throughout the brain. This may explain why the drug appears to alleviate cognitive problems associated with low oxygen. In the long run, it is not known whether the transmission of blood in this way will have any negative effects. (Source: Science Network Xu Xu)
