Intestinal bacteria affect brain health: Study

A new study has found that bacteria in the intestines play an important role in the health of our brain.

Researchers from Washington University School of Medicine in St. Louis, Missouri, us, have found that bacteria in the intestines affect the behavior of immune cells throughout the body. These affected cells also include brain cells, which can damage the brain tissue and cause neurological problems, such as Alzheimer’s.

The findings, published January 13 in the journal Science, showed advances in the possibility of using intestinal bacteria to prevent or treat neurological problems.

According to senior author David M. Holtzman, in the study, the mice were given antibiotics for a week and in their intestinal bacteria, a permanent change in their immune response was observed and it was observed to what extent neurological problems with age were related to a protein called tau.

Interestingly, making changes in these bacteria could be a way to affect the brain rather than inserting something directly into the brain, he said.

There is growing evidence that intestinal bacteria in Alzheimer’s patients may differ from those in healthy individuals. But it is not clear whether these differences are the cause of the disease or the cause of the disease and what effects the changes in bacteria can have during the disease
