Study: a hormone released by the body during sports protects from Alzheimer's disease

The study was conducted by researchers from the Faculty of Medicine at Columbia University and was published in the latest issue of Nature Medicine.

Highlights of the study

• 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.
• Physical activity is known to improve memory, and studies suggest that it could also reduce the risk of Alzheimer's disease, but researchers do not understand why.
• As part of this study, the team discovered for the first time a link between a hormone called erysin-irisin, which increases significantly during exercise, and between the prevention of Alzheimer's disease.
• The researchers found that the secretion of this hormone greatly protects the brain forceps and memory in the hippocampus and improves brain health.
• After badyzing 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.

Statements from the head of the research team:

• "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 found that this hormone promotes also the growth of neurons in the hippocampus of the brain, a space of learning and memory.
• Alzheimer's disease is the most common form of dementia, resulting in continued deterioration of thinking skills, brain function and memory loss.
• The disease is progressively moving towards a loss of ability to perform daily work, to communicate with the ocean, and the condition can deteriorate to the point of becoming ineffective.
