New shot at treating Alzheimer’s patients

A BRAIN-BOOSTING injection which boasts the benefits of a workout could be developed for those at risk of Alzheimer’s.

Exercise has been widely hailed as a positive step in keeping the disease at bay, and irisin, a hormone released during exercise, is now thought to be the key.

Dr Fernanda Felice, who produced the study, done on mice, said: “If researchers are able to move to human clinical studies, in the future there could be an injection of irisin which could help elderly people who cannot exercise.”

It is hoped irisin could work to prevent the disease getting worse in those already affected.
