Patient L had been in a vegetative state for three years, showing no reaction to touch and no response to his family. After he was given the drug, he was able to talk to them. Patient G was also able to interact with family, answer simple questions and catch a baseball. Patient N "was constantly uttering random screams". After he was given the drug, the screaming stopped, and he started watching television and reacting to his family.
I'm not sure watching television should count as awakening from PVS, but it's still amazing. Wesley J. Smith wrote into First Things (curtsies to them) with the comment that this shows we really have no idea what's going on in the minds of those in PVS.
