Tomorrow – NEW YORK (Reuters Health) – According to a recent study, exercise can protect against Alzheimer's disease by stimulating a hormone that helps regenerate brain cells.
The idea that exercise sometimes helps to reduce the risk of dementia has been known for some time or at least not by strangers, but what they do not know, it is safe to say. there is a direct link between sport and disease, reported Sky News. "The British.
After extensive studies, it turns out that when you do exercise, the hormone erysine, a hormone that decreases in the brains of people with Alzheimer's disease, is released and can protect animals from memory loss and brain damage.
The researchers found that mice swimming daily for five weeks did not develop memory deficits despite the injection of beta-amyloid, a protein that blocks brain cells and is associated with patients with dementia. # 39; Alzheimer's.
The study, published in the journal Nature Medicine, suggests that exercise not only protects the brain from dementia, but also a treatment mimicking the hormone Erysin that can prevent this disease.
Dr. Otavio Arancio, professor of pathology, cell biology and medicine at Columbia University, said he encouraged everyone to exercise, to promote brain function and to public health, but pointed out that some people could not, especially those with aging-related diseases, such as heart disease or arthritis. Or dementia.
"For these people, there is a particular need for drugs that mimic the effect of the hormone erysin, protect synaptic points and prevent cognitive and cognitive decline," he said.
There are millions of people with Alzheimer's and dementia in the world, but despite decades of research and attempts, no medicine has been found to reverse the disease or prevent its progression, pushing many large pharmaceutical companies to abandon testing and seek treatment. .
Recent research and studies have shown that erysin promotes the growth of brain cells in the hippocampus, a region of the brain linked to memory and learning.
Two brain regions can regenerate their cells in adulthood and the Ammon horn region is one of the first brain regions to be damaged in people with the disease. ; Alzheimer's.
The results have raised the idea that the hormone Erysin could help explain why sports activity improves memory and seems to play a protective role in brain diseases such as Alzheimer 's disease. Alzheimer's, said Arancio.
Using tissue samples taken from the brain bank, scientists discovered that the hormone erysin was found in the human tonsil and that hormone levels were lower in people with Alzheimer's disease.
Scientists are currently looking for compounds that can increase brain hormone levels or mimic their work.
