Researchers from the University of East Anglia say fecal transplantation may be the “fountain of youth” for cognitive function. Fecal transplantation is usually used to treat patients with Clostridium difficile infection. In some studies involving intestinal bacteria and their potential role in human health, fecal transplantation has become an interesting research topic. New research has found that transplanting bacteria from old people to young people can cause changes in gut bacteria related to deterioration of memory and learning ability. < p > < p > fecal transplantation is to obtain fecal samples from healthy subjects and transplant them to unhealthy subjects. This procedure is not without risks, but it is a good way to treat some dysfunction related to intestinal bacteria. Many studies in recent years have linked healthy gut bacteria to overall health – unfortunately, they seem to age with us and change with age. At present, the decline of cognitive ability is the inevitable result of aging, but it may not be the case in the future. Scientists are looking for ways to maintain or improve cognitive function in the aging population, help them maintain independence, and delay the occurrence of Alzheimer’s disease and dementia. < / P > < p > at present, the research object is mainly experimental mice. It is found that the feces of old mice transplanted to young mice will make significant changes in their intestinal bacteria. This change has a negative impact on cognitive function, and the researchers report that rodents have decreased memory and spatial learning abilities. Dr David vauzour, a researcher, explained: “this process has an impact on protein expression in the key functions of the hippocampus, an important part of the brain, which plays a crucial role in many functions such as memory and learning, as well as spatial navigation, emotional behavior and emotion. In short, young mice began to behave like older mice in terms of cognitive function. < / P > < p > the results of the study have raised new hope that the reversal process may have the opposite effect – the beneficial change of intestinal bacteria may be caused by the fecal transplantation of young, healthy subjects into elderly subjects. However, whether such a change will occur still needs to be further studied. Chinese version of K-car: reading a10e design drawing exposure
