<i>Drugs that could promote neural plasticity could potentially treat a wide range of neurological disorders, as well as boost the effects of other treatments under investigation.</i><p>Just for once, I'd like to hear one of these things say that the discovery could lead to mind blowing lifestyle drugs for everybody. Has it really become so politically incorrect to suggest that we might use science to enhance our lives instead of just helping sick people, or is it just lack of imagination?
So it sounds like if you want to increase the level of growth of new neural connection you would risk losing some (many) of the old ones have have formed. That would be an interesting tradeoff. Definitely somewhere to tread lightly.
