NEW YORK (Reuters Health) – Exercise can protect against Alzheimer's by stimulating a hormone that helps regenerate brain cells, according to a recent study by scientists at Columbia University.
According to the new study, it has been shown that in the exercise of sports, "Erysin" is a hormone that decreases the presence in the brain of people with Alzheimer's disease and can protect animals from memory loss and brain damage.
The mice, who swam daily for five weeks, did not develop a memory deficit, despite the injection of beta-amyloid, a protein that blocks brain cells and is linked to patients with Alzheimer's disease.
The study showed that exercise not only protected the brain from dementia, but also that, according to the agencies, a hormone-simulating treatment "irisin" can be used to prevent the disease.
Recent research and studies have also 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 capable of regenerating cells in the brain. adulthood. In the brain that is suffering damage in people with Alzheimer's disease.
These results suggest that the hormone Erysin may help explain why sports activity improves memory and appears to play a protective role in brain diseases such as Alzheimer's disease.
Using tissue samples taken from the brain bank, scientists found that the hormone erysin was found in the area of human amenorrhea and that levels of the brain were high. hormones were lower in people with Alzheimer's disease.
Scientists are currently looking for compounds that can increase brain hormone levels or mimic their work.
