A daily jab of a bone hormone could reverse memory loss, offering hope for millions of older people who struggle with the cognitive problem as they age.
The amount of osteocalcin – a hormone produced by bone cells – we have in our bodies naturally declines as we age, beginning from age 30 in women and 50 in men.
Now it has been found memory loss can be restored by bringing levels back to when we were young.
Researchers said because it is naturally produced by the body an injection of osteocalcin would be safe.
