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, cognitive decline is an inevitable result of age growth, but it may not be the case in the future. Scientists are looking for ways to maintain or improve cognitive function in aging populations to help them maintain independence while slowing down the occurrence of Alzheimers and dementia.
At present, the research object is mainly experimental mice, the study found that transplanting feces from old mice into 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.
Researcher Dr David vauzour explained: this process has an impact on protein expression in the key functions of the hippocampus - an important part of the brain that plays a crucial role in memory, learning and other functions, as well as spatial navigation, emotional behavior and emotion. In short, young mice began to behave like older mice in terms of cognitive function.
The results have raised new hope that the reversal process may have the opposite effect - transplanting feces from young, healthy subjects into older subjects may lead to beneficial changes in intestinal bacteria. However, whether such a change will occur still needs to be further studied.
