While I think all of this research is cool stuff, I suspect that the medical researchers (or at least the journalists) are drastically underestimating the potential unintended consequences of these drugs/treatments.

I remember reading one critique about memory enhancing drugs. Basically, people forget things for good reason but since (at least at this point) the drugs cannot target specific memories, people were remembering a lot of negative things that they would have been better off forgetting.
