The study was conducted by researchers from the Faculty of Medicine at Columbia University and was published in the latest issue of Nature Medicine.
The researchers said that athletes know that intense exercise can stimulate the body to release a torrent of endorphins, which helps relieve pain, provides a sense of comfort and improvement, and is a good hormone to promote mood.
They said that physical activity was known to improve memory, and studies suggest that it could also reduce the risk of Alzheimer's disease, but researchers do not understand why.
In a rat study, the team discovered a link between a hormone called irisin that increases dramatically during exercise and between the prevention of Alzheimer's disease.
The researchers found that the secretion of this hormone greatly protects the brain and memory clamps in the hippocampus region and improves brain health.
After analyzing tissue samples from human brain libraries, the researchers also found that hormone levels in the cerebral hippocampus were decreasing in people with Alzheimer 's disease.
"It is now proven that exercise produces a hormone that could improve memory and protect against Alzheimer's disease," said Dr. Otavio Arancio, team leader.
"A few years ago, researchers discovered the role of erysin in improving the body's ability to burn fat and energy, but new research has revealed that this hormone could also promote the growth of neurons in the cerebral region of the hippocampus, an essential area of learning and memory. "
Alzheimer's disease is the most common form of dementia, leading to continuous brain damage and memory loss.
The disease is progressively developing to lose the ability to work daily, to communicate with the ocean, and the state can deteriorate to the point of becoming ineffective.
