Age reversal

An experimental drug for Alzheimer's disease appears to have some anti-aging effects, according to a team at the Salk Institute in La Jolla, California. The drug known as J147 improves memory and cognition, leads to healthier blood vessels in the brain and improves other physiological features in laboratory mice. Basically, the drug seems to make old mice look young, says lead author Antonio Currais. The drug takes a different tack to treating Alzheimer's by focusing on the aging process and halting or even reversing it in some sense rather than targeting the amyloid plaques that accumulate in the brain and kill neurones.
