New research provides evidence that exercise can improve Feeling, especially after In life. The study found that older people who exercised regularly had higher levels of a protein important for their brain health than those who didn’t. these were the differences clear even in people whose brains would otherwise show potential signs of dementia, suggesting that exercise may slow Dow Progression of cognitive decline.

The study was carried out by scientists from the US, Canada and Spain. They analyzed data from an existing research project on older adults, memory and aging project Rush dropped out of University in Illinois. As part of the project, volunteers undergo annual medical tests, including measurements of their physical activity. And upon death, they also agree to donate their organs, including their brain, for further research.

the team saw More than 400 volunteers in their 70s and 80s had their physical activity measured over the years and donated their brains for the study. apart from checking For signs of neurological disorders such as Alzheimer’s disease, they examined brain tissue for the presence of proteins important for synaptic function, which is essential for nerve cells to communicate with each other and With other cells.

Overall, they found that adults with higher levels of physical activity had higher levels of these synaptic proteins. This association was also seen in people who had signs of Alzheimer’s and other types of dementia in their brains, such as plaques and tangles. the study’s findings were published This month in Alzheimer’s and Dementia: The Journal of the Alzheimer’s Association.

“The more physical activity, the higher the level of synaptic proteins in brain tissue. This suggests that every movement counts when it comes to brain health,” says the Memory and Aging Center at the University of California San Francisco. Study author Caitlin Casaleto, assistant professor of neurology in . said CNN.

This type of research can only show a connection between exercise and brain health, not demonstrate true cause and effect. But other studies suggested that regular exercise in mid to later life may possibly prevent or delay symptoms of cognitive decline. The team’s findings, Casaleto said, may indicate that exercise helps keep our synaptic function stable as we get older.

The optimal amount of exercise is considered to be at least 150 minutes a week. but this more other research Seems like That any physical activity can do an aging brain good, as long as it can be done regularly.
