Moving and running also help keep the brain in shape. Of course, the Latins already knew that a healthy body makes the soul feel good. But when science clearly confirms the grandmother’s sayings, wise things also become true.
The credit for the discovery (published in November in the Journal of Neuroscience) goes to the University of California San Francisco and the Medical Center of Chicago, which analyzed data from the “Rush Memory Aging” project. This is a large study by Rush University in Chicago, which has been regularly monitoring hundreds of seniors over 80 for years.
Volunteers undergo memory tests and monitoring of their physical activity for a week. Over the years, many of these people have died, giving researchers a chance to analyze their brain tissues. Doctors were able to analyze the material of 167 people.
Post mortem analyzes aimed at identifying the presence of microglia cells. These are cells that take care of the first and main immune defense active in the central nervous system. The activity of these cells has long been known thanks to numerous studies in mice. They are involved in “repairing” brain cells and help keep the brain healthy.
The analysis of the elderly in Chicago highlighted a close relationship between physical movement and microglia, especially in the parts of the brain related to memory. The microglia of people who were more physically active were healthier and more capable of intervening. Not so those of the more sedentary seniors, who also scored lower on cognitive tests.
Same relationship also in brains that showed signs of Alzheimer’s. For those who had even had only late physical activity, the microglia appeared healthy and had no memory loss, despite the presence of the disease.
This study, conducted for the first time directly on brain tissue, shows that physical activity reduces degenerative processes in the brain and also protects against Alzheimer’s.
Here, now you have one more reason to go running. It doesn’t matter if you are young or mature – just do it, it’s for the sake of your brain and your memory. Don’t forget it.
