According to a study published Monday Nature Medicine the hormone irisine, which the body releases in greater amounts during exercise, can prevent memory loss related to Alzheimer's disease.
When the body is exercising, muscle tissue releases the hormone irisin, which circulates in the body and is able to improve cognitive ability, as evidenced by the specialists of the Federal University of Rio de Janeiro and Columbia University (The authors of the study, Ottavio Arancio, Sergio Ferreira and Fernanda de Felice, demonstrated that the increase in the number Irisine, as well as its precursor protein, FNDC5, reduces memory deficit and learning in rodents with Alzheimer's disease
They also observed that when the occurrence of this substance in the brain of sick mice was blocked,
Scientists said the exercise was said to improve cognitive abilities and delay the progression of neurodegenerative disorders, but further studies are needed to better understand how irisine comes into play and interacts with the brain. In addition, they stated that better knowledge was needed to determine if the protein had a similar beneficial cognitive effect in humans.
They however pointed out that the recent discovery could pave the way for new therapeutic strategies serve to alleviate cognitive deterioration in patients with Alzheimer's disease, an incurable disease.
