A literal infusion of some “young blood” has the ability to turn back the clock and restore the mental capabilities of old mice, according to a study conducted by researchers at the Stanford University School of Medicine. If similar results are seen in humans, the simple technique could lead to new treatments for forms of dementia, such as Alzheimer’s disease.
The study builds on previous research conducted in 2011 that showed key regions of the brains of old mice produced more nerve cells when exposed to blood from young mice than did old mice exposed to blood from old mice. Previous experiments also showed that the opposite effect in terms of nerve-cell production was seen when the brains of young mice were exposed to blood from old mice, with their ability to navigate their environments also reduced.
