Scientists from the United States said that in the near future a person may have a chance to overcome the natural processes of aging, and perhaps even suspend them. The study on rodents showed good results and in the plans of scientists carrying out tests on humans.

In their new research project, specialists used the blood of young mice to infuse old individuals, which resulted in improved brain activity in the experimental subjects. Now scientists plan to conduct testing in humans, perhaps this will reveal new methods to combat senile dementia.

In their experiments, scientists injected a one and a half-year-old rodent plasma of 3-month-old mice. The rodents who received similar therapy showed improved memory test results, in contrast to mice of the same age who did not receive plasma.

In the young blood of rodents, there are factors that stimulate the brain of old mice, as a result, it begins to work both at a young age. Now scientists are trying to determine what exactly triggers the work of the brain and what tissues are involved in it. At this stage, specialists can not say exactly whether the same results will be in humans, but a clinical trial involving people has already been scheduled.

As stated in the British fund for the study of Alzheimer's, the procedure of injecting young blood does improve the memory and training of elderly mice, but the significance of this method of treatment for the human body remains a mystery. Despite the fact that this research project is quite interesting, it does not allow to study the violations of cognitive functions that occur in Alzheimer's disease, which develops as a result of natural aging.

However, the following studies can establish how exactly the young blood of mice helps to improve brain performance in old rodents. In the blood of rodents, there is a certain substance that slows the aging process in the tissues of the heart, improves the functioning of the brain. A group of researchers from Harvard University have discovered mechanisms that stimulate the formation of new brain cells in old rodents after infusion of young blood, as well as restoring sense of smell. In addition, this therapy increased the strength of the muscles of old rodents.

Now it's impossible to say exactly whether people will have the same results, and how it will not be influenced by the injection of young blood into the human brain, but Scottish specialists can now say that physical activity positively affects the health of the elderly, and also helps fight senile dementia. In their report, experts from Scotland noted that walking in old age is quite useful for both physical and mental health. In the course of the research, specialists determined that in elderly people who performed walking tours daily (or several times a week), brain activity was better than that of low-active peers. Also, scientists noted that physical exercises are much more useful for the brain than for the body. In addition, physical activity has shown a greater effect on improving brain performance than active social or mental work.
