BBC: "Ketamine 'exciting' depression therapy"

BBC reports that Ketamine (considered a "dissociative anesthetic") has been shown to have some very rapid and dramatic effects on depression in early research studies. As the article describes, there are also potential side effects that are quite serious and "it's not about to replace prozac" anytime soon. They believe that in the future Ketamine itself will not be used, but understanding how it affects the brain will yield new medications with fewer side effects.
