Physical exercise can help counter the loss of memory caused by Alzheimer’s as well as delay the onset of the most common type of dementia, said a study.
Researchers at the Federal University of Rio de Janeiro (UFRJ), established a link between levels of irisin, a hormone produced by the body during exercise, and the development of the progressive disease, Xinhua news agency reported. The tests, carried out on rats with Alzheimer’s, showed low levels of irisin in the brains of Alzheimer’s sufferers, and a reversal in memory loss when irisin levels were boosted through physical exercise. The study showed that “the levels of this hormone are in fact decreased in the brains of patients with Alzheimer’s”, said Sergio Ferreira, a scientist who teaches at the UFRJ.
