As we get older, it becomes more crucial to take care of our minds by engaging in brain-challenging activities and eating a nutritious diet. The completion of crossword puzzles to the consumption of fish high in omega-3 fatty acids are only a few of the methods we might lower our risk of cognitive decline. Nonetheless, there is one vitamin in particular that we don’t typically consider when it comes to improving brain health: selenium.
Scientists from Australia, Germany, and China collaborated on a new study, which was released in the journal Cell Metabolism, to investigate the effects of selenium in the treatment of mental decline. They were interested in learning more about why exercise boosts the creation of brain cells. To this end, they conducted a number of rigorous studies on laboratory mice in order to learn more. In reaction to exercise, the researchers discovered that the mice had generated very high quantities of selenoproteins (proteins holding selenium).
In one trial, the researchers looked at whether it may aid in the improvement of short-term memory. When they gave one group of mice water combined with a selenium solution, they got a different result than when they gave the other group of mice pure water. When it came to memorizing visual signals in order to avoid getting a jolt, the researchers discovered that the mice who drank selenum performed far better than the other group. Following that, the scientists required all of the mice to go through a labyrinth. In this experiment, the selenium-fed mice outperformed the control group once again because they were able to recall their surroundings and locate a route out of the labyrinth more quickly and easily.
During another trial, the scientists looked at the impact of selenium on mice who had had a stroke and were showing cognitive deterioration. They found that it was beneficial. It was discovered that when they gave a few of the mice selenium, the mice’s cognitive ability and memory were restored to normal levels. Mice who suffered a stroke but did not get the mineral supplement, however continued to show cognitive impairment.
The study team discovered that selenium aids in the activation of neural precursor cells, which are cells that have the potential to form new brain cells. It also contributed to the preservation of the quantity of precursor cells which were already in the process of maturing into new neurons. Due to the fact that latent neural precursor cells are a major contributor to cognitive loss in aging individuals, this is significant.
